Abstract:
In analogy to electricity transmission networks, this paper analyzes the concept of supra-regional district heating networks (SR-DHN), connecting a large number of actors. Using a back-casting approach, a SR-DHN is assumed to exist and thus, implementation challenges, such as economic feasibility and energy losses, are circumvented in the first step (but are analyzed in the discourse). The paper then analyzes, in an interdisciplinary qualitative manner and supported by a case study, what technical, operational, economic and legal issues must have been resolved. Results show that the heat transmission network, being the backbone of the SR-DHN, is an expensive infrastructure, but is likely to become economic in a non-fossil energy system. By decreasing the reliance on single waste heat sources, SR-DHN allows longer payback periods and can thus be an enabler for using industrial waste heat. However, involving many actors requires comprehensive contractual foundations. The derived hypothesis is that SR-DHN, which is predominantly fed by waste heat, shall be operated with lower temperatures in winter (feeding the return while minimizing expensive winter losses) and high temperatures in summer (enabling alternative usages while accepting high but inexpensive summer losses).

Abstract:
Abstract The circular economy, which minimises the level of environmental pollution, creates a promising background for sustainable development. The application of bioeconomics principles provides the use of by-products of agriculture, forestry, food waste, and wastewater as raw materials for electricity and heat. The objective is to analyse the prerequisites for bioenergy development as one of the circular economy areas. FGLS estimations are performed over the period of 2007–2018. The leading position in terms of bioenergy sphere growth is occupied by the European Union, followed by the countries of Asia and North America. The division of biomass into “traditional” and “modern” is discussed, where traditional biomass is mostly used for cooking and space heating in developing countries, while the EU is focusing on the development of second-generation (2G) biofuels when the biofuel is produced from non-food raw materials. It is estimated that the annual production of energy from renewable sources is about 225 thousand tons of o. e. in Ukraine. It is found that the legal field and the strategic directions of the bioeconomy in the European Union and Ukraine coincide, but the pace of development of bioenergy in Ukraine can be described as very slow. To increase the bioenergy potential, it is recommended to apply green tariffs, renewable energy certificates, and subsidies to energy producers.

Abstract:
Growing economy is a basis of public well-being, and its rapid growth is implemented on the expense of environmental quality; therefore, the harmonization of different aims and interests is one of the most important aspects of sustainable development concept. One of the priorities of sustainable development in Lithuania – the reduction of building and building materials industries’ impact on environment by increasing their eco and energy efficiency; consequently, the use of waste from renewable resources for the synthesis of chemical materials and production of building materials may reduce the usage of limited sources and emission of greenhouse gases. Such waste open up the opportunities to partially or fully replace traditional materials such as petroleum based polymers or cements which production emits many pollutants, uses lots of energy and natural resources. Nowadays, wood and agricultural waste are used for the production of biofuel; however, such heat source provides with short-term benefit. The use of the above mentioned waste materials for the production of bio-based thermal insulating composites would provide with long-term benefit and contribute to the improvement of currently targeted energy performance of buildings. During the study, it was obtained that the ratios of wood bark/rapeseed binder changes the main parameters of biocomposites. The obtained products are characterized by the density ranging from 329 kg/m3 to 378 kg/m3 and thermal conductivity – from 0.0665 W/(m·K) to 0.0781 W/(m·K). The compressive strength and short-term water absorption have shown that biocomposites can be used as a self-bearing structural materials due its sufficient strength which is approx. 2 MPa and water uptake varies from 20 vol.% to 40 vol.%.

Abstract:
Eco-innovation and green technologies are key to Europe´s future and they are at the heart of the European Union (EU) policies. The EU´s economic prosperity and well being are linked to its natural environment and the global demand for renewable energy and resource-efficient solutions will be a source of new jobs and economic growth in the years to come. As the numerous practical examples from industry demonstrate, eco-innovation is a powerful instrument that combines reduced negative impact on the environment with a positive impact on the economy and society. Eco-innovation call attention to the positive contribution that the small and medium enterprises can make to sustainable development and a competitive economy. To step towards sustainable economic growth, there is a need for much more eco-innovations to appear in small and medium enterprises (SMEs). The aim of the paper is to present the results of empirical research aimed at SME´s involvement in eco-innovation activities in Slovakia and to compare them with the EU 28 average. Our analysis is aimed at five eco-innovation activities contributing deeply to the circular economy. That is a) waste recycling and minimizing waste generation; b) re-planned energy usage to minimize consumption; c) redesigning products and services to minimize the use of materials or using recycled materials; d) changes to the use of water to minimize consumption and to maximize water re-usage; e) usage of renewable energy sources. Identified will be the actual and perceived issues (problems, difficulties) encountered by Slovak SMEs with regard to undertaking eco-innovations. Based on the research results formulated are the implications for SMEs managers and policymakers in Slovakia concerned with the SME´s involvement in ecoinnovation. Our study is qualitative and descriptive in nature and most of the data is based on secondary sources. The data used to assess the SME´s involvement in eco-innovation activities come from the survey commissioned by the EC in the year 2016 with the aim to explore SME´s activities in relation to the circular economy (including the ecoinnovation activities) in the period of years 2014-2016. As to the Slovakia 383 SMEs operating in manufacturing, services and in the industry sector has been interviewed. The methods used in the paper are the methods of causal analysis, deduction, abstraction, comparison as well as synthesis.

Abstract:
Food and agricultural industries have an increasing need to develop and adopt novel and sustainable processing technologies with high processing and energy efficiency and less water usage and waste-water generation while, at the same time, delivering safe, high-quality processed food and agricultural products. The use of infrared (IR) radiation heating for food and agricultural processing represents a novel approach for various food thermal processing operations, including drying, blanching, disinfestation, disinfection, and stabilization. Relevant attributes of IR heating technology include high heat delivery rate, lack of need for a heating medium, reduced processing time, improved energy efficiency, and enhanced product quality and safety with a minimal environmental footprint. The author and his research team recently conducted systematic and innovative research on IR heating for food and agricultural product processing, which resulted in an advancement in the scientific knowledge of IR heating in food science and engineering and the development and commercialization of a series of patented processing technologies. The novel IR heating technologies improved food healthfulness, quality, and safety while saving energy and water. The focus of this article is the review of several innovative IR heating-based processing technologies that were developed, including IR dry-peeling, dry-blanching, and dehydration technologies for fruits and vegetables; IR heating technology for drying and roasting of tree nuts; and effective IR heating for simultaneously achieving multiple goals in rice postharvest processing.

Abstract:
In recent years with the exacerbation of energy shortage, water crisis increases around the world. With the continuous increase in the level of greenhouse gas emissions, the use of various sources of renewable energy is increasingly becoming important for sustainable development. Due to the rising oil price and environmental regulations, the demand of utilizing alternative power sources increased dramatically. Alternative energy and its applications have been heavily studied for the last decade. Energy and water are essential for mankind that influences the socioeconomic development of any nation. Pure water resources become more and more scarce every day as rivers, lakes wells and even seawater pollution rapidly increases. Solar energy is one promising solution to secure power and potable water to future generation. The process of distillation can be used to obtain fresh water from salty, brackish or contaminated water. Water is available in different forms such as sea water, underground water, surface water and atmospheric water. Clean water is essential for good health. The search for sustainable energy resources has emerged as one of the most significant and universal concerns in the 21st century. Solar energy conversion offers a cost effective alternative to our traditional usages. Solar energy is a promising candidate in many applications. Among the alternative energy sources used for electricity production, wind and solar energy systems have become more attractive in recent years. For areas where electricity was not available, stand alone wind and solar systems have been increasingly used. The shortage of drinking water in many countries throughout the world is a serious problem. Humankind has depended for ages on river, sea water and underground water reservoirs for its fresh water needs. But these sources do not always prove to be useful due to the presence of excessive salinity in the water. To resolve this crisis, different methods of solar desalination have been used in many countries. Distillation is a well known thermal process for water purification, most importantly, water desalination. Most of the conventional water distillation processes are highly energy consuming and require fossil fuels as well as electric power for their operation. Single basin solar still is a popular solar device used for converting available brackish or waste water into potable water. Because of its lower productivity, it is not popularly used. Numbers of works are under taken to improve the productivity and efficiency of the solar still. There are large numbers of PCMs that melt and solidify at wide range of temperatures, making them attractive in a number of applications. PCMs have been widely used in latent heat thermal storage systems for heat pumps, solar engineering and spacecraft thermal control applications. The use of PCMs for heating and cooling applications for buildings has been investigated within the past decade. The experimental results computed in the field of water distillation process using solar energy in the presence of energy storage materials sodium sulphate and sodium acetate are discussed in this paper. Keywords: solar energy, saline water, distillation, phase change material.

Abstract:
The energy used by building sector accounts for approximately 40% of the total energy usage. In residential buildings, 30-60% of this energy is used for space heating which is mainly wasted by transmission heat losses. A share of 20-30% is lost by the discarded residential wastewater and the rest is devoted to ventilation heat loss.   The main objective of this work was to evaluate the thermal potential of residential wastewater for improving the performance of mechanical ventilation with heat recovery (MVHR) systems during the coldest periods of year. The recovered heat from wastewater was used to preheat the incoming cold outdoor air to the MVHR in order to avoid frost formation on the heat exchanger surface.   Dynamic simulations using TRNSYS were used to evaluate the performance of the suggested air preheating systems as well as the impact of air preheating on the entire system. Temperature control systems were suggested based on the identified frost thresholds in order to optimally use the limited thermal capacity of wastewater and maintain high temperature efficiency of MVHR. Two configurations of air preheating systems with temperature stratified and unstratified tanks were designed and compared. A life cycle cost analysis further investigated the cost effectiveness of the studied systems.   The results obtained by this research work indicated that residential wastewater had the sufficient thermal potential to reduce the defrosting need of MVHR systems (equipped with a plate heat exchanger) in central Swedish cities to 25%. For colder regions in northern Sweden, the defrosting time was decreased by 50%. The temperature control systems could assure MVHR temperature efficiencies of more than 80% for most of the heating season while frosting period was minimized. LCC analysis revealed that wastewater air preheating systems equipped with temperature stratified and unstratified storage tanks could pay off their costs in 17 and 8 years, respectively.

A case study was thus carried out at an applicable local industry (brewery) to assess the feasibility of implementing the heat pump for waste heat recovery. Through analysis, the focus was narrowed down from a site wide audit, to a departmental breakdown and then eventually to a specific process; the wort boiler. Three different alternatives were investigated and the performance and economic viability compared; a simple waste heat recovery solution involving a vapour condenser (vq, a mechanical vapour recompression (MVR) heat pump and a thermal vapour recompression (TVR) heat pump. It was found that the MVR system yielded the greatest energy savings, followed by the VC and then the TVR system. All three systems had positive rates of return, with the VC and TVR systems being tied for first place.

Abstract:
Urban sprawl, global warming and overused landfills are conditions around the world today, and while people are concerned about these issues they have few practical solutions to them. This creative project seeks to devise a way for a specific sector of business (restaurants), to have a practical way to help reduce global warming and waste while utilizing unused or under-used land in urban areas. While life cycle models are available that address such issues as these, very few case examples are actually in use in this country. Based on existing life cycle models, this project will seek to reuse the wastes from a restaurant and recycle them into a garden/greenhouse (called an urban farm throughout this paper) which will produce food for the restaurant. The three main waste categories from the restaurant to be looked at are the organic kitchen food wastes, water and the heat that is always being expelled from the kitchen while it is operation. Additional ways to make a restaurant more sustainable will also be given. This project will show what the benefits are when a sustainable system is in operation.

Abstract:
The purpose of the thesis is to determine the potential of lessening the high energy cost in the hospitality industry so that the industry could stay alive after a three decades of civil war in Sri Lanka. The hospitality industry is a significant contributor to the country’s economic growth. Tourism industry has much hope of recovering in the year 2010. Improved tourism would also benefit larger part of Sri Lankan population as they are directly and indirectly employed to serve the tourism industry. Sri Lanka has a high electricity production cost as it depends heavily on the imported fossil fuel. Survival of hospitality industry would depend on the manner in which the energy cost - the second highest overhead in hotels is managed. If the industry survives, Sri Lanka would receive more foreign exchange and thereby improve country’s foreign currency reserve which could contribute to high growth rate. As electricity production is mainly depending on thermal, the volatility of world crude oil prices is directly affecting the country’s electricity prices. However, low dependence on the grid would help the hospitality industry to mitigate the energy cost. As the electricity and diesel costs -the highest and the next - are considerable portions in energy cost in hospitality industry, the study aims to discuss the possible ways of mitigating such costs. Measurements done by the presenters found that the usage of electricity for air conditioning system does constitute most of the electricity consumption for a hotel whilst most of the diesel consumption is for thermal applications. If Air Conditioning (AC) can be operated without electricity and thermal applications could be operated using abundantly available alternative energy sources then the overall energy costs of hospitality industry could be reduced thereby making higher profits. This would ensure industry survives and country gets more foreign exchange.  Study and calculations done by the presenters proved that operating of generators only for electricity production is not viable, due to high fossil fuel cost, however if its high exhaust temperature which is wasted otherwise, could be utilized for operation of absorption chillier then the dependence of grid electricity for air conditioning could be minimized. Further studies also revealed that if water cooled generator is used for such purpose instead of air cooled, and then the hot water requirement of hotel also could be fulfilled, thus mitigating the dependence of fossil fuel which is used otherwise for hot water production. Study also revealed that if thermal energy could be fed with biomass- Sri Lanka being a tropical country is blessed with abundantly available biomass - then the dependency on the fossil fuel for thermal applications could be avoided. This would not only mitigate the second highest energy cost for hotels but also create less carbon foot print, more environmental friendly and produce less noxious exhaust gases thereby creating an advertisement to attract tourists who longing to support green hotels

Abstract:
Current global agricultural practices are recognized as unsustainable. The increase in overall human population as well as the global trend of rural to urban migration, partially as a result of historically and continual unsustainable agricultural practices, exacerbates the vicious cycle of poverty and hunger in developing countries. Furthermore, cities and regions in developed countries practice unsustainable food production, distribution and consumption patterns, and as a result, exceed their global ecological footprint (Rees 2009). Consequently, the world is facing a global food (FAO 2009) and water crisis (UN Sick Water 2010). Cities and Regions must learn to feed themselves to address local food insecurity as well as protect from the climate effects of increased urbanization, including the Urban Heat Island effect (UHIe) by optimizing and fully integrating the local ecosystem services of food, water and forest within a tightly woven compact urban form through the implementation of strategic urban and regional food system planning. Cities can mitigate climate change and reduce the UHIe, by implementing sustainable intensive urban agriculture approaches through policy and zoning interventions that include concepts such as intensively productive urban agriculture that includes green roofs, vertical farming and greenways as continuously productive and edible urban landscapes, referred to in this paper as continuously productive urban agriculture and forestation (CPUAF) in the private and public realm. A highly participative, adaptive systems approach is explored as the key to sustainability within an economic world order that included corporate social responsibility and social enterprise as the foundation for the integration of multiple synergies. An increasing body of evidence often links urban forestation with urban greenery initiatives, as a carbon sink to reduce UHI effects, to reduce GHG emissions and as a tool for urban beautification and place making (ISDR: 2009,109). Urban agriculture, through the production of local food is increasingly recognized as a means to reduce fossil fuel emissions by reducing transportation and production outputs, to provide a secure local food source, enhance biodiversity and educate the public regarding food source while fostering a sense of community, environmental awareness and stewardship. This thesis explores the links between intensive urban agriculture and forestation, and the relationship between climate change, and the UHI’s as an adaptation and mitigation process in global cities, implemented as a interconnected, integrated, holistic urban management approach that has a further benefit of providing food security and a sustainable and local urban food source.

Abstract:
Aufgrund von steigenden Energiekosten und einer sukzessive steigenden öffentlichen sowie politischen Forderung nach Umweltbewusstsein und Nachhaltigkeit, ist die Effizienzsteigerung von Gesamtsystemen einer der treibenden Kräfte für innovative, technologische Neuheiten geworden. Besonders bei der Entwicklung von verbrennungsmotorisch angetriebenen Fahrzeugen wurden z.B. durch die Hybridisierung von Antriebssträngen, die die Rekuperation von kinetischer Energie ermöglichen, Technologien zur Energieeinsparung etabliert. Da bei Verbrennungsmotoren ein hoher Anteil der im Kraftstoff gespeicherten Energie technologiebedingt als Abwärme im Abgas verloren geht, bietet die Wärmerekuperation ein weiteres hohes Potential für weitere Einsparungen. Diese ist z.B. mit Hilfe von thermoelektrischen Generatoren (TEG) möglich, die einen Wärmestrom direkt in elektrische Energie umwandeln. Zur effizienten TEG-Systemgestaltung ist ein hoher Temperaturgradient über dem thermoelektrisch aktivem Material notwendig, der wiederum zu kritischen thermomechanischen Spannungen im Bauteil führen kann. Diese werden zum einen durch die unterschiedlichen Temperaturausdehnungskoeffizienten der verschiedenen Materialien und zum anderen durch die mechanische Anbindung auf der heißen und kalten Seite des TEG verursacht. Somit liegt ein Zielkonflikt zwischen dem thermoelektrischen Systemwirkungsgrad und der mechanischen Festigkeit des Bauteils vor. In dieser Arbeit wird mit Hilfe einer mehrkriteriellen Parameteroptimierung eines vollparametrisierten FE-Modells des TEG in ANSYS WORKBENCH eine Methode vorgestellt, den thermoelektrischen Wirkungsgrad bei gleichzeitiger Reduktion der thermomechanischen Spannungen zu optimieren. Zur Optimierung kommt dabei ein genetischer Algorithmus der MATLAB GLOBAL OPTIMIZATION TOOLBOX zum Einsatz. Der Modellaufbau wird in ANSYS WORKBENCH mit der Makro-Programmiersprache JSCRIPT realisiert. Als Ziel- und Bewertungsfunktionen wird die mechanische Belastung jedes Bauteils im TEG ausgewertet und dessen elektrische Leistungsdichte berechnet. Die Ergebnisse zeigen, dass mit Hilfe der vorgestellten Methodik eine paretooptimale Lösung gefunden werden kann, die den gestellten Anforderungen entspricht.

Abstract:
För att tillgodose framtidens växande behov av energi och samtidigt bidra till en långsiktigt hållbar energitillförsel krävs resurs- och energieffektivisering inom flera sektorer. Inte minst inom industrin som år 2016 stod för mer än 50 procent av det globala energibehovet. Tillvaratagandet av befintliga resurser såsom spillvärme från tryckluftsproduktion är en möjlig effektiviseringsåtgärd. Till grund för examensarbetet ligger ett önskemål från koncernen Sandvik AB att utreda besparingspotential och kostnader för reinvestering i en av industrins kompressorcentraler, Götvalsverket. Reinvesteringen avser två nya kompressorer vars spillvärme integreras i industrins befintliga närvärmesystem och möjliggör för minskade resurs- och energikostnader samt utsläpp av CO2. Arbetet syftar till att analysera olika kompressorlösningar utifrån ett ekonomiskt och miljömässig perspektiv. Detta görs med hjälp av insamlad data, känslighetsanalyser och lönsamhetskalkyler med tillhörande LCC. Målet är att kunna besvara olika frågeställningar rörande total investeringskostnad, energi- och resursbesparing samt utsläppsreducering. Två fall av produktion undersöks, dels vid drift enligt Götvalsverkets befintliga produktionstid och dels med en optimerad drifttid för kompressorenheterna. En litteraturstudie har också genomförts där flera studier visar att tryckluft är ett dyrt alternativ för energiproduktion och att implementering av effektiviseringsåtgärder, däribland återvinning av spillvärme, därför kan vara väl grundade investeringar. Även andra fördelar kan kopplas till energieffektivisering, exempelvis förbättrad produktion och arbetsmiljö för anställda. Resultatet av arbetet visade att särskilt ett kompressoralternativ stod ut från de övriga ur både en ekonomisk- och miljömässig synpunkt. Detta alternativ erbjöd inte den billigaste investeringen men däremot var mängden återvunnen värme så pass mycket större än för andra alternativ, att energibesparingen minskade återbetalningstiden drastiskt. Tillvaratagande av befintliga resurser som spillvärme, tillsammans med industrins minskade energianvändning, anses vara en nödvändighet för att kunna säkerställa välmående hos både människor, djur och natur i framtiden.
In order to meet the growing demand for energy in the future, while contributing to a long-term sustainable energy supply, resource and energy efficiency measures are required within several sectors. In 2016 the industry sector accounted for more than 50 percent of the global power demand. The use of existing resources, such as waste heat from compressed air production, is a possible efficiency measure.  Behind this thesis work is a request from the Sandvik AB Group to estimate savings potential and reinvestment costs in one of the industry's compressor centers, Götvalsverket. The reinvestment refers to two new compressors whose waste heat is integrated into the industry's existing district heating system and allows for reduced resource and energy costs as well as a reduction of CO2-emissions.  This work aims to investigate different compressor alternatives from an economic- and environmental perspective. This is done using collected data, a sensitivity analysis and profitability calculations with an attached LCC-analysis. The aim is to answer various questions regarding total investment cost, energy and resource saving as well as emission reduction. Two cases in production are investigated. The first according to the existing operation hours in Götvalsverket and the second case with an optimized operating time for the compressor units.  A literature review has also been conducted where several studies show that compressed air is an expensive alternative to energy production and that implementation of efficiency measures, including waste heat recovery, can be well-founded investments. Other benefits can also be linked to energy efficiency, such as improved production and an improved work environment for employees.  The result of the work showed that one alternative in particular stood out from the other compressor solutions, both from an economic and environmental point of view. This option did not offer the cheapest investment but the amount of recovered waste heat was much larger than for the other alternatives and therefore, energy savings reduced the payback period drastically.  The utilizing of existing resources such as waste heat, together with the industry sector’s reduced energy consumption, is considered a necessity in order to ensure the well-being of people, animals and nature in the future.

Abstract:
AbstractGlobal climate change impact is predicted to affect various sectors including the energy demand and supply sectors respectively. Combating this impact will require adoption of both global strategy and localized actions. The use of low carbon strategy based on renewables is a global strategy, while waste management of biodegradable materials through the use anaerobic technology to meet energy demand is a local action. Nigeria is among the vulnerable countries to global climate change impact; this is even more aggravated by its dependence on fossil fuel usage as well as poor waste management, which two, contribute significantly to greenhouse gas emissions. This chapter presents analysis of purified compressed biogas production, a waste conversion option, as a local action to meet rural household energy demand and contribute to global strategy of reducing climate change impact. It discusses both technical and business model approaches to upscale a laboratory experimental procedure for biogas production through anaerobic digestion using vegetal wastes. It shows that using anaerobic technology can achieve efficient waste management and at the same time generate energy that can be used to achieve avoided emissions for climate change impact reduction. The study also concludes that upscaling the project will be sustainable for rural energy augmentation as it produces clean and renewable energy, reduces the use of fossil fuels, provides jobs for skilled and unskilled labor, and generates new return streams.

Abstract:
Sustainable (environmentally friendly) modern construction is not limited only to use of natural and environmentally friendly materials. The concept of the construction is an important factor and that is applied to local materials, especially if they come from renewable sources. The sustainable (environmentally friendly) building principles, methods of construction from straw, the essential building requirements for construction from straw are discussed in the article. Straw as a building material used for a very long time, but this usage is often associated with certain mistrust, fears: the building will burn, the mice, rats are attacking, etc. Straw building uses raw materials which are agricultural waste. Buildings constructed from straw decompose in the end of their lifecycle and the construction waste in the area of construction is biodegradable, consequently, it is not necessary to take them away to a landfill. The evaluation of the global and Lithuanian experience of using straw and the structures in which straw are used shows, that the essential requirements can be provided if the straw and timber-framed buildings with straw as a heat insulating material are constructed properly, they use to meet the essential requirements according to the Law on Construction and the European Council and Parliament Regulation No 305/2011.

Abstract:
The development of sustainable, cost-effective, reliable, efficient and stable materials and methods for continuous fresh water production is crucial for many regions of the world. Among the many other options, graphene nanoflakes seem to be good option to solve the global water problem due to their low energy cost and simple operational process to purify waste water. The produced water can be used for drinking, agriculture, gardening, medical, industrial and other purposes. Most of the nanofilter-based multifunctional fresh water systems do not require large infrastructures or centralized systems, and can be portable to remote regions for efficient water treatment. Graphene was discovered as a single-layer of isolated graphite atoms arranged in 2D hexagonal shape, making it the thinnest and strongest material known to date. Despite its intriguing mechanical, thermal and electrical properties, usage of graphene for different industries has not been investigated in detail. The present study investigated the availability and practical use of graphene inclusions for desalination of salt water to produce fresh water. In the present study, graphene was added to 3.5wt% salt water (similar to sea water) at different percentages. Graphene has a high absorption capability to convert solar energy into heat to enhance the evaporation rate of salt water. The graphene inclusions can also be used to remove bacteria, viruses, fungi, heavy metals and ions, complex organic and inorganic compounds, and other pathogens and pollutants present in various water sources (e.g., surface, ground water, and industrial water).

Abstract:
Sustainability is an issue of great importance in the building and energy sectors. In the United States, about 40% of total energy use is in buildings, 30% of raw materials are used in buildings, 30% of waste outputs come from buildings, 30% of greenhouse gas emissions are attributed to buildings, and 12% of potable water consumption occurs in buildings. Thus, there is a great necessity for the rapid deployment of highly sustainable buildings that are aesthetic and reliable. Solar houses are highly sustainable and can be designed to be reliable by using streamlined technologies, providing as much power as needed, and by minimizing the energy usage within the building. The US DOE Solar Decathlon offered a great opportunity to test these criteria which were at the same time the fundamental elements taken into consideration when designing the Santa Clara University (SCU) solar house in 2007 [1]. In this research the SCU solar decathlon solar house energy and thermal performances were analyzed. The energy and thermal loads were modeled using EnergyPlus™ software which helps to perform detailed modeling of the energy and thermal performances of buildings. The conditioned space of the building consists of two rectangular shaped zones, the living room and the bedroom, which together are approximately 45ft along the east-west direction and 11ft wide. Wood framing with R-19 insulation, made from recycled jeans, was used for the walls. The roof and the floor are constructed of a bamboo wood frame with foam insulation. Daylighting was maximized through active windows (i.e. electro-chromic), energy efficient appliances were incorporated along with solar thermal air conditioning, heating and hot water. Performance parameters for the mechanical systems were developed from conventionally available technologies and the control set-points were based on DOE Solar Decathlon 2007 (SD07) guidelines [1]. The thermal energy design decisions for the house were based largely on a combination of the solar decathlon contest requirements and that technologies were sustainable and commercially available. The house was tested in Washington DC in October 2007 during the competition and performed excellently well ranking at the top in the following categories: energy balance, thermal comfort, and hot water. Data collected during the event provide the unique opportunity of validating the simulated energy and thermal performances of the house with weather file created from the real-time weather data. The created weather file is used to run new simulations of the SCU SD07 house, from these results we can assess the accuracy of the simulation program used. If accuracy is high enough, annual simulations are executed to demonstrate how the house would perform under extreme climatic conditions in different regions.

Abstract:
High thermal efficiency of LNG liquefaction plants is of importance in order to minimize feed usage and to reduce CO2 emissions. The need for high efficiency becomes important in gas constrained situations where savings in fuel auto consumption of the plant for liquefaction chilling and power generation can be converted into LNG production and also from the standpoint of CO2 reduction. This paper will provide a comprehensive overview of waste heat recovery approaches in LNG Liquefaction facilities as a measure to boost thermal efficiency and reduce fuel auto-consumption. The paper will cover types of heating media, the need and use of heat for process applications, the use of hot oil, steam and water for process applications and direct recovery of waste heat. Cogeneration and combined cycle approaches for LNG liquefaction will also be presented along with thermal designs. Parametric studies and cycle studies relating to waste heat recovery from gas turbines used in LNG liquefaction plants will be provided. The economic viability of waste heat recovery and the extent to which heat integration is deployed will depend on the magnitude of the accrual of operating cost savings, and their ability to counteract the initial capital outlay. Savings can be in the form of reduced fuel gas costs and reduced carbon dioxide taxes. Ultimately the impact of these savings will depend on the owner’s measurement of the value of fuel gas; whether fuel usage is accounted for as lost feed or lost product. The negative impacts include the reduction in nitrogen rejection that occurs with reduced fuel gas usage and the power restrictions imposed on gas turbine drivers due to the increased exhaust system back-pressure caused by the presence of the WHRU. When steam systems are acceptable, a cogeneration type liquefaction facility can be attractive. In addition to steam generation and hot oil heating, newer concepts such as the use of ORCs or supercritical CO2 cycles will also be addressed.
