Purpose Enhancing household consumption and reducing inequality are among the fundamental goals of many developing countries. The purpose of this study therefore is to disaggregate household consumption expenditure into food and non-food and, thus, decompose inequality into within- and between-groups. Design/methodology/approach The study adopts generalised entropy (GE) measures. Second, the study uses regression-based inequality decomposition to ascertain the determinants of inequality in food and non-food expenditure using household demographic and socioeconomic characteristics as covariates. Findings The results show that non-food expenditure is the major source of inequality in household consumption expenditure in both urban and rural areas with inequality coefficients of above 0.6 compared to about 0.4 for food expenditure. The decompositions also show that within-group inequalities for non-food and food expenditure are, respectively, 0.97 and 0.365 using the Theil index, while between-group inequalities for non-food and food are, respectively, 0.016 and 0.035. Furthermore, the regression-based inequality decompositions show that variables such as living in rural areas, household size, household dwelling and household dwelling characteristics account for the significant proportion of inequality in food and non-food expenditure. Originality/value The policy implication of the findings, among others, is that policies should focus on addressing inequality within rural and urban areas, especially with respect to non-food expenditure than in inequality existing between urban and rural areas. These non-food expenditures include expenditure in education, health, energy, accommodation, water and sanitation.

Full textAbstract:
As part of more stringent energy targets in Switzerland, we witness the appearance of new green-certified dwellings while many existing dwellings have undergone energy efficiency measures. These measures have led to reduced energy consumption, but rarely consider their impact on indoor air quality. Consequently, such energy renovation actions can lead to an accumulation of radon in dwellings located in radon-prone areas at doses that can affect human health. This study compared the radon levels over 650 energy-efficient dwellings in western Switzerland between green-certified (Minergie) and energy-renovated dwellings, and analyzed the building characteristics responsible of this accumulation. We found that the newly green-certified dwellings had significantly lower radon level than energy-renovated, which were green- and non-green-certified houses (geometric mean 52, 87, and 105 Bq/m3, respectively). The new dwellings with integrated mechanical ventilation exhibited lower radon concentrations. Thermal retrofitting of windows, roofs, exterior walls, and floors were associated with a higher radon level. Compared to radon measurements prior to energy renovation, we found a 20% increase in radon levels. The results highlight the need to consider indoor air quality when addressing energy savings to avoid compromising occupants’ health, and are useful for enhancing the ventilation design and energy renovation procedures in dwellings.

Full textAbstract:
Zhalantun city is located in a severely cold region of China. The cold climate and long winter bring challenges to the energy-saving design of rural dwellings in this area, while the poor economic conditions restrict the application of energy-saving technology. This paper aims to propose an optimal combination of passive design parameters by investigating, testing, and analyzing simulations of Zhalantun rural dwellings, which have a particular architectural pattern. Field measurements during winter show that the indoor temperature of a traditional house is low and fluctuates greatly, and the inner surface is prone to easy condensation. Through thermal comfort surveys, neutral and acceptable temperature ranges were obtained to provide indoor calculation parameters for an energy-saving design. Numerical simulations of heating energy consumption were conducted on the typical building models using DesignBuilder. The influence of different design factors on energy consumption was evaluated. Orthogonal experiments were designed to optimize a series of design parameter combinations to reduce the energy consumption of Zhalantun rural houses and to determine the sequence and significance of the effect of these design factors on energy consumption. Results show that the optimal parameter combination based on orthogonal experiments can obviously reduce energy consumption and have better economic benefits without considering mechanical methods. This can provide a basis for improved energy-saving designs and indoor thermal environments in such rural dwellings.

Full textAbstract:
Energy waste due to inhabitants' behavior in residential buildings has emerged as a potential research area due to the increasing worldwide population and growing energy needs. However, existing approaches for simulating energy consumption are mainly limited to office buildings and are based on static profiles. In this paper we propose a 4-step co-simulation methodology to assess how inhabitants' interactions with household appliances affect energy consumption. The approach is validated using a case study showing how human activities influence the energy consumption patterns of a refrigerator. The fridge was specifically chosen because it is a high energy-consuming appliance that is strongly affected by inhabitants' behaviors. In addition, modeling the fridge is nontrivial, and in choosing this appliance we show that it is possible to apply the approach to less complex appliances. A co-simulation approach is adopted with the fridge being physically modeled in Matlab and with human behavior being modeled in the Brahms language and simulation environment. The consumption distribution from the simulated scenario is compared with the actual distribution (using data from a consumption database), to find optimum values of tuning parameters with less than 10% variation. This methodology enables us to simulate how human behaviors affect energy appliance consumption.

Full textAbstract:
The objective of this paper was to compare primary energy consumption and energy efficiency during the operation phase of different types and combinations of water heating systems in single-family dwellings. Systems with an electric shower, liquefied petroleum gas heater, and solar heater with electric backup were analysed. The analysis was performed by means of computer simulation using EnergyPlus. Three Brazilian cities with different climates were assessed, i.e., Curitiba, Brasília and Belém. The systems were compared in terms of final energy and primary energy consumption. Results showed that systems with an electric shower, which have a lower water flow rate, led to lower primary energy consumption. The solar heating system combined with an electric shower was the option with the lowest energy consumption, and the solar heating system with a heating element in the storage tank was the option that consumed more energy. The systems were sized according to the requirements of the Brazilian energy efficiency labelling for residential buildings, and the efficiency level was compared to the results of primary energy consumption. The electric shower was found to be the third lowest energy consumer, but it was ranked the least energy efficient by Brazilian labelling, while systems with high energy consumption, such as gas heaters and solar heaters with a heating element in the storage tank, were ranked the most energy efficient. Therefore, a review of the requirements and methodology of the Brazilian energy efficiency labelling for residential buildings is recommended in order to encourage the use of truly efficient systems. Public policies that encourage solar heating systems should establish requirements regarding the configuration and sizing both the solar heating system and the backup system.

Full textAbstract:
In current research, building modelling and energy simulation tools were used to analyse and estimate the energy use of dwellings in order to reduce the annual energy use in multifamily dwellings. A three-story residential building located in Kabul city was modelled in Revit and all required parameters for running energy simulation were set. A Total of 126 experiments were conducted to estimate annual energy loads of the building. Different combinations from various components such as walls, roofs, floors, doors, and windows were created and simulated. Ultimately, the most energy efficient option in the context of Afghan dwellings was figured out. The building components consist of different locally available construction materials currently used in buildings in Afghanistan. Furthermore, the best energy efficient option was simulated by varying, building orientation in 15-degree increments and glazing area from 10% to 60% to find the most energy efficient combination. It was found that combination No. 48 was best option from energy conservation point of view and 120-degree rotational angle from north to east, of the existing building was the most energy-efficient option. Also, it was observed that 60% glazing area model consumed 24549 kWh more electricity compared to the one with 10% glazing area.

Full textAbstract:
Res-IRF is an energy-economy model of heating consumption in French dwellings developed at CIRED and calibrated against 2012. It is meant to project the evolution of the building stock and the heating demand by 2050 in response to socio-economic parameters, such as energy price and population, and public policies, such as thermal regulations or incentives for renovation. Res-IRF captures the relevant determinants of household decisions related to energy efficiency improvements and energy demand (sufficiency). The aim of the work presented in this report is to calibrate the model against a past year, to run it from this start date to 2012, and to compare the simulation results with observed data on this period. After an overview of the French residential sector in the last 40 years, this report aims at presenting the model and how it was calibrated against year 1984 and adjusted to the past situation of the building stock. Then, the results of a sensitivity analysis on key parameters of the model are compared to reality and it is discussed how the model can be improved to fit the data better. The main results show that the model accurately replicates the evolution of the building stock until 2012. However, the results do not fit well the data of repartition of heating fuels, especially for fuel oil and natural gas. This may be due to the structure of the model which allows fuel switch only for renovating dwellings; then it could miss possible fuel switches from fuel oil to natural gas without renovation due to the expansion of the natural gas network in France between 1980 and 2000. Furthermore, the actual unit consumption, which is a key output of the model, is well replicated by the model, with an error of 5 to 10%.Res-IRF är en energi-ekonomi modell av värmebehovet i franska byggnader utvecklad av CIRED och kalibrerad mot data för 2012. Det är avsett att förutsäga utvecklingen för byggnadsbeståndet och värmebehovet fram till 2050 med utgångspunkt från socio-ekonomiska parametrar såsom energipriser och befolkningsmängd, politiska beslut som regleringar rörande uppvärmningssektorn och incitament för renoveringar. Res-IRF fångar upp de relevanta faktorer som påverkar hushållens beslut relaterade till förbättringar av energieffektiviteten och energibehoven. Målet med arbetet som presenteras i denna rapport är att kalibrera modellen mot ett redan passerat år, att köra modellen från startåret till 2012, och att jämföra simuleringsresultaten med verkliga observationer för denna period. Efter en översikt över den franska bostadssektorn de senaste 40 åren, följer i rapporten en presentation av modellen och hur den kalibrerades mot året 1984 och sedan anpassats till det dåvarande läget i byggnadsbeståndet. Därefter jämförs resultaten av en känslighetsanalys av nyckelparametrar i modellen med verkligt utfall och en diskussion följer om hur modellen kan förbättras för att bättre passa verkliga data. Huvudresultaten visar att modellen på ett korrekt sätt avbildar utvecklingen av byggnadsbeståndet fram till 2012. Däremot ger resultaten inte god överensstämmelse vad gäller fördelning av bränslen, speciellt inte fördelningen mellan olja och naturgas. Detta kan bero på modellens struktur, som tillåter bränslebyte bara vid renovering; därmed missar den bränslebyten som görs utan samtidig renovering, som tillkommit på grund av utbyggnaden av naturgasnäten i Frankrike mellan 1980 och 2000. Vidare visar modellen god överensstämmelse vad gäller energitillförsel per enhet, vilket är en nyckelparameter bland resultaten från modellen. Denna parameter predikteras med ett fel av 5 till 10%.

Full textAbstract:
Energy including electricity plays a significant role in the economic development of a country as it enhances the productivity of capital and labour. Many of the developing countries are plagued with energy problems: predominantly by their over dependence on low quality, traditional fuel and the over reliance on imported commercial fuel-oil. Some of the problems associated with energy forecasting in developing countries may include lack/insufficient data. This study was conducted in two phases and begun with the reviewing of literature on energy and the different determinants of energy in a developing nation. Access to electricity is particularly crucial to human development as electricity is, in practice, indispensable for certain basic activities, such as lighting, refrigeration and the running of household appliances, and cannot easily be replaced by other forms of energy. Yet, many developing countries are faced with the challenge of providing adequate and modern energy services to its communities, which in turn is expected to improve the standards of living through increased income and employment generation. The second phase of this research was developing and modelling demand for residential electricity using secondary data. This task was challenged by the inadequacies in the quality and availability of data on the one hand and the unrealistic assumptions of many existing models used to predict energy consumption in developing countries on the other. The contribution of this thesis here was also to consider a wider set of factors that are traditionally used in energy modelling. Many previous studies had been focusing on income as a determining factor affecting demand for energy (for example, the energy ladder theory). However, this study found that there are many other factors such as the informal economy (activities within the economy that is not declared or included in the gross domestic product of a nation), urbanisation and transformation from rural to urban areas that may have a significant impact on how energy in the residential sector is demanded. It was therefore important to exceed beyond unquestioned assumptions of the orthodox belief and to focus on the processes of urbanisation and change as realities facing many developing countries. In order to develop a deeper understanding and analysis of the residential energy sector, this research offered a thorough examination of the literature on modelling techniques, their underlying theories and assumptions and the choice of variables and measurements. This led to the selection and identification of the factors influencing energy demand and helped determine the modelling techniques finally used in the thesis. In order to achieve the aims of the study, a mixed method approach was adopted. The use of quantitative (secondary and primary) data as well as qualitative (case studies, face-to-face interviews and semi-structured questionnaires) helped the researcher to test a number of established hypotheses and offer a deeper understanding of the questions in hand. Through using various statistical techniques the study was able to examine the relationship between different selected variables which can help forecast the demand for residential energy. Furthermore, with the use of a structured questionnaire survey of the households, socio-economic data were collected from 501 households in Ibadan metropolis in Nigeria which provided the premise for understanding factors other than income that are responsible for determining the type and level of energy consumed in households. The analysis involved the use of ordinal regression as households neither use the same fuel in the same combination or at the same level. In sum the thesis made the following contributions: i) a better understanding of households energy consumption which have implications for a successful energy analysis for households in Nigeria as well as other developing countries; ii) a tested methodology for analysing the determinants of household energy. The results showed that household income and price of energy do not have a significant effect on the consumption of energy in the household. It was rather factors such as the location of the property, the ownership status of the property and the expenditure spent on energy that seemed to be more relevant in determining the consumption of energy in the households. The evidence from the study suggests that there is divergence in the energy need of households and hence the different determinants for various fuels. The concept of energy ladder as suggested by earlier researchers was not confirmed by the findings. Instead the study supported the work carried out by Heltberg (2003) and confirmed that income alone may not be sufficient to determine the consumption of energy by a household. It was rather factors such as the location of the property, the ownership status of the property and the expenditure spent on energy that seemed to be more relevant in determining the consumption of energy in the households. This research also highlighted the importance of the various socio-cultural factors that affects the consumption of energy within the household, and in the same vein, it showed that economic contribution is not the sole determinant in the choice of fuel energy.

Full textAbstract:
This study examines the change in the space heating energy consumption and its associated cost and carbon emissions following retrofit energy efficiency upgrade. 3 to 4 week fuel consumption and temperature data were collected from some 1500 dwellings over two successive winters in 2001/2002 and 2002/2003. The case study dwellings were occupied by elderly householders or families with young children and were either awaiting or had received a combination of draught proofing, insulation and central heating measures under England’s Warm Front Scheme. The findings show that the Warm Front Scheme resulted in a mean increase of 1.6 °C in indoor temperature and a mean increase of 12 % in fuel consumption. Nevertheless, the switch from electricity to gas for space heating following the introduction of gas boilers resulted in a mean reduction in heating cost by 7 %. The scheme was found to have negligible impact on carbon emissions. Characteristic differences were observed with individual energy efficiency measures. Central heating resulted in the greatest temperature rise by 2.3 °C followed by insulation by 0.7 °C with a negligible impact from draught proofing. Clear evidence was found in householders increasing the demand temperature following the introduction of a central heating system while no evidence of this was found following the introduction of insulation. In terms of energy use, insulation resulted in a mean saving of 9 % but fell short by 74 % to 84 % from the theoretical prediction while central heating resulted in a mean increase of 29 % in the energy consumption. Draught proofing was found to have little impact on the energy use. When examined in terms of energy cost, insulation and central heating all resulted in mean cost savings of 13 % and 9 % respectively but falling short by 55 % to 72 % and 57 % to 82 % compared to their respective theoretically predicted mean cost savings. Insulation also resulted in mean carbon emissions saving of 13 % but fell short by 56 % to 73 % from the theoretical prediction while central heating resulted in insignificant carbon emissions saving. Combining insulation with central heating was found to be beneficial in terms of mitigating the energy consumption rise associated with central heating from 29 % down to 16 % while maximizing the temperature gain by as much as 3.1 °C.

This paper explains typical knee wall construction and insulation in homes in Indiana and demonstrates the energy inefficiencies caused by such methods. Literature research gives examples of possible opportunities for changing the standard methods of knee wall construction and insulation. The methodology of the study is explained, as is energy intensity (EI) — the main evaluation tool used in this paper. EI allows a researcher to compare homes of different sizes in different locations. Overall, the study shows that homes whose knee walls have an air barrier backing use less energy than homes without knee walls. Additionally, as expected, homes with improperly constructed knee walls use the most energy. Finally, the paper contains recommendations about what methods might be used to change the standard practices involved in building and insulating knee walls.Department of Urban Planning

The perception of thermal comfort is an important factor influencing the acceptability of residential heating strategies. The perceived thermal comfort may affect a person's inclination to try a strategy or to use it on a long-term basis. In the study, perceived thermal comfort was assessed in relation to room temperature, humidity, clothing worn, preferred room temperatures, personal control over the temperatures, and energy consumption. The relationships among these variables were examined for five families participating in a live-in study comparing five residential heating strategies. The strategies tested included closing off bedroom vents/doors, setting the thermostat at 65°F, and the use of a solar greenhouse and a woodstove as supplemental heat sources. The families lived in a retrofitted solar test house for a period of four to six weeks. The house was equipped with a computer which monitored 37 channels of information at ten-second intervals and recorded the data hourly. The data collected included temperatures in every room, inside and outside humidity, wind velocity, and other variables that interplay in comfort levels and energy use. The ten adult respondents completed daily and weekly questionnaires containing Likert-type scales of thermal comfort and checklists of clothing worn. The results suggest the following conclusions: 1) the use of a residential setting to measure thermal comfort under varying environmental conditions can be successfully accomplished, 2) psychological variables such as personal control should be considered and tested by persons involved in standards development for the thermal environment, 3) the ability and experience of the persons to use a strategy can affect the achieved energy saving benefits of the strategy, 4) personal preference in the amount of personal effort a person is willing or able to give will impact on the decision on whether to use certain strategies, 5) heating strategies that can produce a direct source of heat or at least some warmer areas were rated higher by the project participants, and 6) weather can play an important role in the effectiveness of the solar greenhouse as a heating source.Ph.

Full textAbstract:
Installation and utilization of residential distribution transformers has not changed substantially over a long period of time. Utilities typically size their transformers based on a formula that takes into account broadly what types and how many dwellings will be connected.
Most new residential dwellings feature 200 Amp service per household with an anticipated energy demand of under 20,000 kWh per year. Average electrical energy consumption varies from state to state but averages to 11,280 kWh per year. Energy demand is expected to fall into a typical residential load curve that shows increased demand early in the morning, then decreasing during the day and another peak early to late evening. Distribution transformers are sized at the limit of the combined evening peak with the assumption that the transformer has enough thermal mass to absorb short overloads that may occur when concurrent loading situations among multiple dwellings arise. The assumption that concurrent loading is of short duration and the transformer can cool off during the night time has been validated over the years and has become standard practice. This has worked well when dwelling loads follow an averaging scheme and low level of coincidence.
With the arrival of electric vehicles (EV's) this assumption has to be reevaluated. The acquisition of an electric vehicle in a household can drive up energy demand by over 4000 kWh per year. Potentially problematic is the increased capacity of battery packs and the resulting proliferation of Level 2 chargers. The additional load of a single Level 2 charger concurring with the combined evening peak load will push even conservatively sized distribution transformers over their nameplate rating for a substantial amount of time. Additionally, unlike common household appliances of similar power requirements such as ovens or water heaters, a Level 2 battery charger will run at peak power consumption for several hours, and the current drawn by the EVs has very high levels of harmonic distortion. The excessive loading and harmonic profile can potentially result in damaging heat build-up resulting in asset degradation.
In this thesis I present a device and method that monitors pole mounted distribution transformers for overheating, collect and wirelessly upload data and initiate commands to chargers to change output levels from Level 2 to Level 1 or shut down EV charging altogether until the transformer returns into safe operational range.

Full textAbstract:
Energy demand reduction has become a global issue involving all countries, including China. As major energy consumers in today s society, the need for buildings to be built and operated more energy efficiently is well recognized. In 1995, the national standard on building energy efficiency in China (JGJ 26-95) was refined and updated to become the new residential Buildings standard (JGJ 26-2010) published in 2010. In the new version, many changes have been made to support the construction of more energy efficient buildings in China. For example, in the new standard, all buildings are highly recommended to install personal control on the heating system, such as by Thermostatic Radiator Valves (TRVs), together with pay for what you use tariffs. Previous practice comprised uncontrolled heating with payment based on floor area. In order to reduce building energy consumption, Chinese government has revised the Chinese building design standard. In the new guide the use of individual room temperature control is highly recommended for new and refurbishment buildings. However, evidence to quantify the extent to which this improvement impact upon on the building energy consumption is currently lacking. This thesis evaluates the impact of updated building design standards on thermal conditions and energy consumption in Chinese residential buildings. In order to evaluate the impact on the building energy consumption, two types of residential buildings have been chosen, one complying with the old Chinese building design standard, while the other complies with the new standard. The study was carried out in seven apartments in each type of building, a total of fourteen apartments and comprised with a longitudinal monitoring of indoor air temperature, outdoor air temperature, window position and energy consumption of each apartment. The impact of the new design standard has been evaluated in relation to a number of aspects, that include building construction, indoor thermal environment, occupant behaviour, thermal comfort and building energy consumption. It is concluded that updating the building design standard has had a positive influence on the building conditions and energy consumption. Furthermore, a thermal comfort survey was carried out in both new and old apartments according to updated standards. The results show that the Predicted Mean Vote (PMV) model has a efficiently adequate predictor of occupants thermal comfort in both type of apartments. Thereby allowing confirmation that the new control refine did not compromise on thermal comfort. The percentage of acceptable of occupants is higher in new apartments compared with the old apartments.

AbstractEnvironmental degradation, soil erosion, and desertification are some of the consequences of high rate of traditional biomass fuel use by households in developing countries. The critical issues to raise here are how can these households be encouraged to change their energy consumption behavior? What are the factors that cause the rampant use of biomass fuel in developing countries? How and to what extent can these factors be manipulated so that households in developing countries are encouraged to adopt clean energy fuel an alternative to the most widely used biomass fuel? Therefore, this chapter tries to find answer to the above questions raised, by carrying out an in depth analysis of households’ use of biomass fuel in developing countries using Bauchi State, Nigeria, as the case study. Cluster area sampling technique was utilized to generate the various responses, where a total number of 539 respondents were analyzed. The study estimated ordered logit model to analyze the factors that influence the movement of households along the energy ladder from nonclean energy to the cleaner energy. Furthermore, Ordinary Least Squares (OLS) model was estimated to analyze the impacts of socio-economic, residential, and environmental factors on biomass energy consumption. It was found that age of the household head and his level of education, income, living in urban areas, home ownership, and hours of electricity supply have positive and significant impact on household energy switching from traditional biomass energy use to the cleaner energy. Therefore, policies that will enhance household income and the increase in the availability of cheap cleaner energy will encourage households switching to cleaner energy sources thereby reducing the level of environmental pollution in the study area.

In Smart and Sustainable Planning for Cities and Regions, 129–40. Cham: Springer International Publishing, 2021. http://dx.doi.org/10.1007/978-3-030-57764-3_9.
Full textAbstract:
AbstractThe influence of urban density on household electricity consumption is still scarcely investigated, despite the growing attention to building energy performance and the electrification of heating systems advocated at the European level. While the positive correlation between urban sprawl developments and the increasing of marginal costs of public infrastructures, services, amenities, public, and private transports are known, there has been little research on the relationship between urban form and electricity consumption in residential building stock. The present work aims to contribute to filling the gap in the existing literature, presenting the early results of ongoing research on the role of urban form in the household electricity consumption in Italy and, consequently, the related energy costs. The building typology and, in general, the structure of urban dwellings, is crucial to forecasting the electricity requirements, taking into account single housing units and their spatial composition in multi-family homes and neighborhoods. After a brief literature review on the topic, the contribution presents empirical research on the electricity consumption at the municipal level in 140 Italian cities, analyzing the diverse consumption patterns under different conditions of urban density to verify whether there exists a significant statistical correlation between them. The analysis confirms that there is a statistically negative correlation between urban density and the log of electricity consumption, even if its incidence is very limited. Further investigation may highlight whether there exists a threshold for which this relationship would be reversed, explaining the higher electricity consumption in dense metropolitan areas.

Full textAbstract:
This chapter is on the use of the Sustainable Development Goals (SDGs) for the achievement of green economy in Nigeria with the specific aim of assessing the performance of key issues in the SDGs. Five goals SDGs 6, 7, 11, 12, and 15 for water and sanitation, safe human settlements, renewable energy, sustainable consumption and production, and ecosystem, respectively, are selected for assessment for the green initiatives and the economy. Budgets on economic and social services follows the pattern theory: that government allocates and reallocates at will without cognizance of the population's interests. The assessment holds the fact that only two of these goals are being met somehow—renewable energy and clean water—and not necessarily because of the need to achieve the goals but as part of private sector and dynamic market initiatives, clearly indicating failures for the others. For the most part, Nigeria failed in the areas of ecosystem, good human settlement, and responsible consumption. The chapter suggests the encouragement of entrepreneurial initiatives, the initiation of new policies on green economy, and the enforcement of regulations already in place to power the economy.

Full textAbstract:
According to the National Energy Balance (1), the electricity consumption in the residential and commercial sector represents thirty-three percent of the total consumed in the country. Most of the energy is consumed during the summer, when it is necessary to use air conditioning to maintain comfort conditions inside buildings. This aspect takes relevance in warm-dry climates, where a deficient design of building envelope and a wrong location of windows can increase the thermal loads producing an extra load to air conditioning systems and high costs by electricity energy consumption. For this reason, adequate design strategies and thermodynamic concepts have to be applied in order to make dwellings comfortable. Two dwellings are simulated and analyzed, the first one is made of regional materials like traditional concrete block walls, reinforced concrete roofs and economic finishes, the second one is proposed with a green roof and insulation in walls. The heat gains through the different constructive elements have been obtained, to analyze their impact on global thermal comfort and the electricity energy consumption of air cooling systems. Also, an exergy analysis has been applied to analyze exergy efficiency of air cooling systems and the influence that the building envelope can have in them with the proposed changes. The minimum exergy expenditure of air conditioning systems required to achieve comfort conditions inside dwellings could be a useful benchmark for the comparison of various dwelling designs.

Full textAbstract:
Abstract The objective of this paper is to perform an energy optimization study using pinch analysis on the Heat Exchanger Network (HEN) of a Crude Distillation Unit to maximum heat recovery, minimize energy consumption and increase refining margin. The heat exchanger network (HEN) considered comprises exchangers from the pre-heat section of the atmospheric distillation unit, which recovers heat from the product streams to incrementally heat the crude oil feed stream before entering the furnace. This paper illustrates how to perform a detailed HEN retrofitting study using an established design method known as Pinch Analysis to reduce the operating cost by increasing energy savings of the HEN of an existing complex refinery of moderate capacity. Analysis and optimization were carried out on the HEN of the CDU consist a total of 19 heat exchangers which include: process to process (P2P) heat exchangers, heaters and coolers. In the analysis, different feasible retrofit scenarios were generated using the pinch analysis approach. The retrofit designs included the addition of new heat exchangers, rearrangement of heat exchanger (re-sequencing) and re-piping of existing exchangers. Aspen Hysys V9 was used to simulate the CDU and Aspen Energy Analyser was used to perform pinch analysis on the HEN of the pre-heat train. Several retrofit scenarios were generated, the optimum retrofit solution was a trade-off between the capital cost of increasing heat exchanger surface area, payback time, energy / operating cost savings of hot and cold utilities. Results indicated that by rearrangement (Re-sequencing), the pre-heat train can reduce hot (fired heat) and cold (air and cooling water) utilities consumption to improve energy savings by 8% which includes savings on fired heat of about 4.6 MW for a payback period of 2 years on capital investment. The results generated were based on a ΔTmin of 10°C and pinch temperature of 46.3°C. Initial sensitivity analysis on the ΔTmin indicated that variation of total cost index is quite sensitive and increases with increase in ΔTmin at the temperature range of 14.5-30°C, however total cost index remains constant and minimal at a temperature range between 10°C-14.5°C for the CDU preheat train under study. In addition, the implementation of the optimum retrofit result is straightforward and feasible with minimum changes to the existing base case/design.

Abstract The world is fast changing and so is the energy mix. A global clarion call by scientists inspires an immediate action to circumvent the visible effects of climate change or face the damning consequences in the coming few years. Scientists and environmental lobbyist are campaigning against the consumption of fossil-based fuel and mounting more and more pressure on the international financial bodies including calling on government around the world to refrain from further financing of fossil fuel projects. This is surprisingly gathering momentum on regular basis, thereby posing existential threat to third-world oil producers, which are largely dependent on royalties and tax revenues from crude oil and other natural resources in order to sustain their economies. The future trends warn of a looming dooms day when these remaining reserves may no longer be able to attract the requisite funding necessary to develop them, let alone explore them. Besides Niger Delta, most other petroleum basins in Nigeria are highly under-explored but presumed to have significant hydrocarbon resources, albeit mainly gas. For that reason, these basins and their resources do not yet count in the nation's wealth of booked resources. It is believed the country can also benefit from significant amounts of oil discoveries that are invisible to conventional technologies or intentionally bypassed in natural recovery methods. These could present less costly alternatives to uplift the nation's reserves booking and in so doing minimize uncertainty involved in deep water or frontier explorations. Nigeria should therefore aim to ramp up its capital investment to boost oil & gas production in the next couple of years so as to harness th abundant discovered resources whilst there is still time to do so. To take advantage of Nigeria's vast portfolio of hydrocarbon resources, the nation must explore strategic policies aimed to enhancing exploration and production interests while simultaneously expanding other value chains and promoting the investment in alternative or renewable energy. It must expediently exploit the remaining reserves so as to make the most of what it has. Then the wind fall from that exploitation can be ploughed back into the economy to facilitate the implementation of large-scale alternative energy projects as it plans to eventually substitute the fossil fuel energy. This paper presents some thought-provoking but radical ideas of how this can be achieved in the near term.

Full textAbstract:
Energy consumption is an important issue and has become a great concern during last the few decades, where most energy consumption is utilized for conditioning buildings. The solar chimney is a natural ventilation technique that has the potential to save energy use in buildings as well as maintain comfortable indoor quality. The objective of the current study is to examine the effects of the wall-solar chimney on airflow distribution and thermal conditions in a room. In the current work, computational fluid dynamics was used to model a solar chimney. The time-dependent conservation equations for mass, momentum and energy were solved with the k-ε turbulence equations using ANSYS Fluent. Previous literature, that utilized numerical modeling to study the solar chimney for different dimensions of chimney geometry, only considered a two-dimensional solar chimney with one-directional heat transfer. In the current study, the solar chimney was modeled three-dimensionally for a more realistic simulation of actual flow and thermal condition of the room. Experimental and numerical data from literature were used to validate the current model, and the results agreed very well. The current study showed that the flow in the solar chimney system can be either laminar or turbulent depending on the parameters of the system, and that the effect of the chimney inlet is more significant than that of the air gap on the flow regime. This study also developed a new characteristic Rayleigh number Ra* relating the chimney inlet and the air gap, which showed good consistency with the prediction of the flow regime. The investigations on Ra* and the flow regime indicated that the flow becomes turbulent for Ra* ∼ 0.8 × 108. Lastly, the potential improvements of the designs were discussed by observing the flow and thermal condition of the room.

Full textAbstract:
ABSTRACT Domestic utilization of natural gas in Nigeria is being hampered by the poor developments in the natural gas sector over the years, with low level of electricity (generation) consumption per capital, weak legal, commercial and regulatory framework amidst poor infrastructural developments in natural gas as compared to that which exists for oil. Nigeria ranks the second in gas flaring and shows low volumes of domestic gas utilization, consuming only about 11% out of the 8.25 billion cubic feet produced per day in 2014 despite its natural gas resource endowment. This paper examines the determinants of domestic utilization of natural gas in Nigeria from 1990-2013. It investigates its relationship as a function of price of natural gas, price of alternative fuels, foreign direct investment, volumes of gas flared, electricity generated from natural gas sources and per capital real GDP. Going further, it forecasts its likely growth rate for a short-term period, using an econometric methodology of ordinary least squares and an ARIMA model, it estimates the relationship between the variables and uses the historical trend to forecast into the future. The result of the study showed that the determinants jointly explain the pattern of domestic gas utilization in Nigeria by 98%. Individually, per capital real GDP, electricity generated from natural gas sources and changes in the volume of domestic utilization of natural gas was found to have a positive and significant effect on domestic gas utilization. Further, the forecast values show evidence of a slow but gradual increase in utilization pattern in the near future from 2015-2020. A best-case scenario of an increase of 0.15% and a worst-case scenario of a decrease of 0.14% was presented. In conclusion, having identified significant influences on domestic gas utilization patterns in Nigeria it is imperative that the government uses economic instrument to enhance the utilization patterns in Nigeria by improving economic activities and developing the power sector which shows significant influence in domestic natural gas utilization patterns.

Full textAbstract:
The security of energy supply has become an important issue for energy-dependent countries due to increasing energy demand and energy input prices in recent years. Therefore, energy-dependent countries have developed energy safety strategies to reduce dependence. However, the environmental problems that occur because of the increase in energy consumption, countries had to adopt an economic development process, sustainable development strategies taking account of environmental factors together with economic growth. Thus, an energy input and optimal energy policies have become increasingly important. This paper investigates the real energy efficiency by decomposing the structural and production activities and energy consumption changes of MINT countries, namely, Mexico, Indonesia, Nigeria and Turkey for the period of 1990-2014 utilizing Logarithmic Average Division Index Method. The results show that Mexico uses energy more efficiently among the countries. Mexico is followed by Indonesia, Turkey and Nigeria, respectively.

The rapid increase in global communication infrastructure in developing countries has drawn significant attention to the telecom sector. However, the dismal performance of the power sector in some countries like Nigeria poses a great challenge to the telecom industry which requires a reliable, efficient and environmentally friendly energy supply. Unstable electric grids, an erratic power supply, non-availability of trained and skilled personnel, and a prohibitive cost of site maintenance cumulatively have increased the need to harness abundant renewable energy sources, such as solar and wind. A comparative study of the viability of solar-diesel hybrid against diesel-only generator systems in powering a base station using the cost of kilowatt hour (kWh) self-generated electricity and levelised cost of energy (LCOE) was undertaken using data from some sites located in the Southwest (SW) and the Northeast (NE) regions of Nigeria. Homer Pro Software was used in data analysis. The results obtained showed that with a hybrid energy system (solar and diesel generator), there were 79% savings in fuel consumption, 83.2% savings in operation and maintenance cost for the hybrid energy system in the SW. The savings on fueling as a result of the use of hybrid systems was 86%, and the carbon footprint reduction was 76%. Furthermore, the cost of operation was reduced by 51% for Northeast. The LCOE for the solar hybrid system was determined to be $1.44 for NE1A and NE1B while that of NE2A was $1.46 and NE2B $1.47.

Full textAbstract:
This research paper provides a regional review of the state of electricity access in Sub-Saharan Africa (SSA), focusing on installed capacity, electricity generation, the growth of renewable energy, electricity consumption, government investment, public financial flows, and several major initiatives. The study contrasts electrification between 1990 and 2010 with recent efforts and identifies countries that are consistently making progress and those that lag. The analyses show signs of progress on scaling up SSA power infrastructure and increasing electricity access, particularly in the Eastern and Western sub-regions. The installed generation capacity expanded at an average rate of 2.43 GW/year between 2005 and 2015. Renewable energy is growing, particularly solar, wind, and geothermal; about 9.7 GW of renewable energy capacity was installed between 2010 and 2016. Over this period, the net electricity generation in SSA increased at 9.1 TWh/year, more than double the historical average growth of 4.02 TWh/year (1990–2010). In general, the study found that rates of electrification across the entire region are more than twice the historical rates, and an average of at least 26 million people are now gaining access to electricity yearly. Nevertheless, progress is uneven across SSA. As of 2016, almost half of the population without electricity access live in Nigeria, DR Congo, Ethiopia, Tanzania, and Uganda. Quantitative analysis suggests that about 70 million people in SSA would have to gain access every year from 2017 to achieve universal access by 2030. Overall, SSA countries with national programs on energy access supported by policy/regulatory framework and infrastructure investment are making progress.
