Abstract:
In the European Union buildings are responsible for 40% of total energy consumption. Reducing energy use and the use of energy from renewable sources in the construction sector is an important measurement needed to reduce the Union's energy dependency and greenhouse gas emissions. The Energy Performance Certificates (EPCs) of a building is intended to declare and display the energy performance of the building, presented in a unitary synthetic form, detailing the main building characteristics and associated facilities resulting from the thermal and energy analysis. The Energy Performance Certificates (EPCs) is in fact an energy balance of the analyzed building. For a good cohabitation, in case of "Green Houses[i]" it is necessary to be anchored in reality, to be aware of the impact that a construction - used for living or for other activities- has on the environment.

Abstract:
Many university campuses in the United States are working toward their sustainable goals by adopting energy or green building policies, which require Leadership in Energy and Environmental Design (LEED®) certification for new construction and major renovation projects. Because LEED certification heavily relies on whole building energy simulation to demonstrate building energy performance improvement, it is often assumed that the finished buildings will achieve the predicted level of energy efficiency. This paper presents a study that compares the energy model predictions with actual energy performance of three LEED buildings on a university campus. The study shows that one of the campus LEED buildings consumed twice the predicted energy usage while causing a high level of occupant dissatisfaction. Further investigation reveals a variety of contributing factors for these issues and provides insights to improve green building policy and practice. Not only are the research findings important for this particular campus (Ohio State University) on its way to sustainability, they also have widespread ramifications for other university campuses.

Abstract:
The construction sector as one of the highest carbon emitters in the World has an international initiative for Green House Gas reduction. Green building certifications demonstrate performance, efficiency and economy in the constuction sector. The motivation of the research was to investigate whether Green certified buildings which fulfill the minimum energy standards do demonstrate high energy performance compared to energy efficient buildings and renewable systems. The hypothesis was to investigate that renewable energy source application could contribute to higher performance, against a typical efficient HVAC system (usually applied in commercial buildings) and a building aiming for Green certification, concerning mandatory energy efficiency requirement. The research scope was to investigate and evaluate various HVAC solutions using triple-criteria evaluation method for decarbonization: energy performance, carbon footprint and operation cost to formulate systematic solutions in the design phase of projects for wide audience with preferable and applicable results.

Abstract:
Leadership in Energy and Environmental Design (LEED) is a national set of standards put forth by the U. S. Green Building Council in 1994 that was intended to inspire building designers to plan greener, more sustainable buildings. LEED offers up to ten points for improved energy optimization performance. It should be noted that achieving these ten points is time consuming, complex, and expensive. This research is a case study that details the process of using a computer simulation study as a building energy optimizing tool in order to achieve these optional points. Determination is made as to how many LEED points can be obtained when basic strategies such as window performance and day-lighting are integrated into one energy optimized building design. The results show that well-established energy conservation methods achieve as few as two or three LEED energy points, thereby possibly offering a disincentive for designers to attempt this difficult challenge. These fundamental efforts to achieve energy optimized building design are the first steps toward high performance building design and offer a fundamental solution to the substantial, negative environmental impacts caused by buildings today.

Abstract:
Building energy certification is stipulated by law in the majority of the European countries. The intention of these regulations is to offer key performance indicators (KPIs) to relevant and interested stakeholders. Another motivation for implementing these calculation schemes was to compare the energy performance of different buildings. However, existing guidelines for building energy evaluation do not comprehensively outline the input data collection process and the derivation of substantial KPIs. Furthermore, practitioners do not share a common understanding of the approach to energy certificates, resulting in different practical methods and different interpretations of the calculation guidelines. As a result, the envisioned comparability between buildings is not ensured, as a number of studies illustrated in the past.This contribution focuses on a specific uncertainty in building energy evaluation input data, pertaining to zoning and usage assumptions. Toward this end, two case studies are presented. A number of existing buildings (typical Viennese building stock) were subjected to the Austrian normative energy certification calculation. Thereby, different scenarios regarding the zoning and usage profiles of the buildings were developed. On the one hand, the calculated performance of individual (residential) units was compared with the calculated performance of the whole building. On the other hand, calculations considering different usage assumptions in different zones within the building (detailed calculation) were compared to results based on generalized assumptions for the whole building. The evaluation of the case study buildings showed significant differences in KPIs, given different input data (depending on the case study, heating demand showed deviations up to 50%). The results emphasize the importance of a clear documentation of input data assumptions for building-related energy assessment.

Abstract:
Energy performance certification (EPC) of buildings results in a label for the buildings. Every label has to correspond to a fixed energy consumption per year. Energy consumption taken as a basis for the certification is to reflect efficiency of energy use in buildings and stimulate the occupiers to become more aware of the effect of their behaviour. The method of energy performance efficiency calculation is proposed and numerical values of annual energy consumption are elaborated on the ground of these two aims, European Union requirements and Dutch experience as energy performance efficiency indicators.

Abstract:
Energy certification of buildings in Serbia was introduced in 2011 and energy label depends on energy need for heating per unit floor area of heated space, calculated by the fully prescribed monthly quasi-steady-state method defined by ISO 13790. In the Republic of Serbia, most of families live in single-family houses built before the energy certification of buildings was introduced. Therefore, the estimation of energy performance of the existing buildings is important for labeling, and evaluation of energy saving measures and energy strategies to be implemented. This paper examines the applicability of monthly method defined by National legislation on the existing buildings stock in Serbia, by comparing it to the more accurate dynamic simulation method. Typical single-family houses are taken as a test case, since they are responsible for about 76% of energy consumption for heating. The results show that the dynamic simulation method estimates 21% to 54% higher energy need for heating, compared to the monthly method. Also, the monthly method estimates up to 13% higher savings by typical building envelope energy saving measures, compared to the dynamic simulation. This paper recommends improvement in procedures for calculation of building energy performance index to better assess energy consumption, effects of energy saving measures, and create solid background for developing and implementing of energy saving strategies.

Abstract:
Recent studies have identified that buildings all over the world are great contributors to energy consumption and greenhouse gas emissions. The relationship between the building industry and environmental pollution is continuously discussed. The building industry includes many phases: extraction of raw materials, manufacturing, construction, use, and demolition. Each phase consumes a large amount of energy, and subsequent emissions are released. The life cycle energy assessment (LCEA) is a simplified version of the life cycle assessment (LCA) that focuses only on the evaluation of energy inputs for different phases of the life cycle. Operational energy is the energy required for day-to-day operation processes of buildings, such as heating, cooling and ventilation systems, lighting, as well as appliances. This use phase accounts for the largest portion of energy consumption of the life cycle of conventional buildings. In addition, energy performance certification of buildings is an obligation under current European legislation, which promotes efficient energy use, so it is necessary to ensure that the energy performance of the building is upgraded to meet minimum requirements. For this purpose, this work proposes the consideration of the energy impacts and material resources used in the operation phase of a building to calculate the contribution of these energy impacts as new variables for the energy performance certification. The application of this new approach to the evaluation of university buildings has been selected as a case study. From a methodological point of view, the approach relied on the energy consumption records obtained from energy and materials audit exercises with the aid of LCA databases. Taking into practice the proposed methodology, the primary energy impact and the related emissions were assessed to simplify the decision-making process for the energy certification of buildings. From the results obtained, it was concluded that the consumption of water and other consumable items (paper) are important from energy and environmental perspectives.

Abstract:

The major climatic problem has been worsening extremely rapidly over the last decades and if no measures are taken soon, we will experience severe consequences over the years to come. It is therefore imperative to take instant actions to slow down the climatic changes that are also causing crucial health problems in different parts of the planet. The basis of this thesis is that both Energy Performance Certification (EPC), and Green Building (GB) aim to reduce carbon dioxide emission within the building sector which accounts for more than 40% of the total energy use both locally and globally. This thesis discusses and compares the environmental impacts made by Green Building and Energy Performance Certification in order to evaluate how different or similar they are in terms of energy performance efficiency of buildings.

 

In order to accumulate as much facts and resources possible, research was done to find reliable internet sources and relevant books which took approximately two weeks. The rest of the ten weeks that were assigned for this project were spent writing this thesis while taking practical part in an Energy Performance Certification process and evaluation. There are three questions that this thesis is aimed to answer, which are:

-               How is Energy Performance Certification beneficial for our community welfare?

-               Why should owners/occupiers choose to transform their houses/buildings to Green Building certified constructions?

-               Is there a way of combining Energy Performance Certification with Green Building?

 

There are many benefits that our Swedish and European Community can gain from applying Energy Performance Certification of building according to the Directive, including reducing carbon dioxide emission and introducing alternative and renewable sources of energy. As to whether GB is better than EPC or vice versa, there is ultimately a very fine line that divides the two. When comparing new constructions of EPC with new constructions of GB the only benefits that can be gained from GB are firstly that the buildings are guaranteed to be completely environmental friendly, and secondly that the owner/occupier may choose between four different levels of certifications. Other than that, they both have many similar beneficial factors which make it difficult to a state if one of them is better than the other.

 

Lastly, it is very possible to combine the two into one complete standard, but only for new constructions. The energy performance of old existing buildings is much more difficult to improve due to e.g. the high costs involved or the cultural value of the constructions. Nevertheless, this may very well change in the further future when the rapidly improving technology within the building sector will hopefully contribute to finding cost- and energy-efficient solutions for existing buildings that will consequently contribute to GB and EPC being able to combine their regulations and make one single standard that can be applied in all the Member States, or if possible in the entire European Union Community.


De allvarliga klimatproblemen har förvärrats i oerhört snabb takt under de senaste decennierna och om inget görs snart, kommer vi att få uppleva allvariga konsekvenser under de kommande åren. Det är därför absolut nödvändigt att agera snabbt för att bromsa ner klimatförändringarna som också orsakat allvarliga hälsoproblem i många delar av jorden. Utgångspunkten för detta examensarbete är att både Energideklarationen och Green Building strävar efter att minska koldioxidutsläpp inom byggsektorn, som ansvarar för mer än 40 % av den totala energiförbrukningen i Sverige och utomlands. Detta arbete diskuterar och jämför Green Buildings och Energideklarationens påverkan på miljön för att sedan kunna evaluera hur pass lika eller olika de är när det gäller energiprestandaeffektiviteten av byggnader.

 

För att kunna samla så mycket information som möjligt gjordes en undersökning för att hitta pålitliga Internetkällor och relevanta böcker. Undersökningen tog ungefär två veckor. Resten av de tio veckorna som var tilldelade för detta examensarbete användes för att skriva denna rapport samt praktiskt delta i en Energideklarationsprocess samt värdering. Det finns tre frågor som detta examensarbete syftar på att besvara, som är:

-               Hur viktig är Energideklaration för vårt samhälles välbefinnande?

-               Varför ska fastighetsägare välja att bygga/omvandla sina hus till Green Building?

-               Finns det något sätt att kombinera Energideklaration med Green Building?

 

Det finns många fördelar för det svenska samt europeiska samhället med att tillämpa Energideklaration enligt Direktivet. Fördelarna inkluderar minskning av koldioxidutsläppen samt introducering av alternativa förnybara energikällor i byggnader. Dock är det i slutändan små faktorer som skiljer Green Building och Energideklaration åt och det är därför svårt att säga om den ena är bättre än den andra. Vid jämförelse av nya EPC konstruktioner med nya GB konstruktioner är den enda fördelen med GB först och främst att byggnaden är garanterad att vara helt miljövänlig samt att ägaren har möjligheten att välja mellan fyra olika certifieringsnivåer. Förutom detta, har båda två många likheter som gör det svårt att bedöma om den ena av dem är effektivare än den andra.

 

Det är dessutom mycket möjligt att kombinera dessa två till en enda komplett standard, dock endast för nya konstruktioner. Gamla befintliga byggnaders energiprestanda är mycket svårare att förbättra på grund av t.ex. för höga kostnader eller det kulturella värdet av byggnaderna. Å andra sidan kan detta mycket väl ändras i framtiden då den snabbt utvecklade teknologin inom byggsektorn förhoppningsvis kan bidra till att hitta kostnads- och energieffektiva lösningar för befintliga byggnader som kan i sin tur leda till att GB och EPC kombineras till en enda standard som kan tillämpas i alla Medlemsstater, eller även i hela Europa om möjligt.

Abstract:
The main aim of this thesis is  to demonstrate and critically assess life cycle approaches’ and environmental certification (EC) tools’ potential for supporting decisions for improved environmental performance in the building and real estate sectors. Using life cycle approaches, the thesis shows that for new build and renovation cases aiming for low operational energy use that embodied global warming potential (GWP) due to material production can constitute a large portion of a building’s lifetime GWP. Therefore life cycle based information about materials’ embodied GWP needs to be made available to and utilized by design process decision makers. It was also shown that applying the Swedish EC tool Miljöbyggnad was useful in highlighting potential positive and negative changes in indoor environmental quality arising from renovation packages aiming at significant operational energy use reduction in existing multifamily buildings. However such renovation packages are not profitable from a property owner perspective. Miljöbyggnad may be useful when designing policy instruments to overcome this.    The thesis also showed that EC and related environmental enhancements contribute to achieving property owners’ and tenants’ overall strategic objectives for value creation. For property owners this arises for example through lower energy costs and attracting desirable tenants. For tenants, value creation arises as support for internal and external environmental communication. For the further development of life cycle approaches’ and EC tools’ application to buildings and real estate it is important to consider how they can be adapted to consider ‘distance to sustainable’ targets referencing for instance the planetary boundaries approach. It is also interesting to investigate how valuation of buildings and real estate may be performed in a way that expands from the current narrow focus on the economic perspective to also include environmental and social perspectives.

Abstract:
The aim of this project was to develop a holistic approach to building-performance assessment without limiting it to energy use (usually expressed in kWh/m2/year), but rather include more parameters that represent the following aspects: Economic, environmental, and quality of service provided to the occupant/client. If it can be shown that buildings can be operated not only in an energy-efficient way, but also in a way that takes into consideration the needs of the occupants, a case could be built that a higher quality of indoor environment does not necessarily mean a higher economic impact. It is also important to show that having access to high-quality building-performance data leads to high-quality analysis and visualisation, and consequently to a chance to detect faults and improve building operation. To answer these questions, a large office building in Stockholm, Sweden was used as a case study. The building was equipped with energy meters and 1,700 sensor points, uniformly distributed over the occupied areas, that measured room temperature, duct temperature, occupancy presence/absence and supply airflow, in addition to other states. The data was processed using RStudio, and various types of visualisation plots were used, including carpet plots, masked scatter plots, bar plots, line graphs, and boxplots. The data pointed to some interesting results. First, just knowing the energy use is not sufficient for understanding the quality of the service provided to the occupants. Second, performing a thorough analysis of room unit data can detect faults. Third, using carpet plots for energy-data visualisation is effective for energy-use pattern recognition. Finally, visualising the building performance parameters in a parallel coordinate plot is a more informative representation of integrated building performance compared to the energy performance certificates typically used today.

Tese de mestrado integrado, Engenharia da Energia e Ambiente, Universidade de Lisboa, Faculdade de Ciências, 2019
O consumo energético do setor residencial representa cerca de 30% do consumo global de energia. Parte deste consumo de energia é relativo a sistemas de aquecimento e arrefecimento, para proporcionar condições de conforto térmico ao utilizador, necessário ao seu bem-estar. A quantificação e caracterização do consumo energético em edifícios pode ser utilizada como material para estudos em cenários de utilização, previsão de comportamento energético, mapeamento de pobreza energética e estudo de impacto de políticas energéticas. Uma das soluções já testada para a caracterização do consumo energético foi a elaboração de um modelo estocástico, que gera dados sintéticos com base nas características de desempenho energético de uma amostra reduzida. Estes dados além de necessitarem de uma atualização, carecem de tratamento focado na vertente regional (NUTS III) e nacional, bem como no contexto e no ano de construção da habitação. O objetivo primário relativo ao tema proposto passa pelo tratamento e análise dos dados em bruto provenientes da Certificação Energética de Edifícios feita pela ADENE - Agência para a Energia no âmbito do Sistema de Certificação Energética, cujo conteúdo são dados relativos à certificação energética de cada elemento da amostra de edifícios residenciais, como parâmetros físicos e indicadores de desempenho energético. Outro objetivo é a criação de um modelo computacional que permita caracterizar e analisar diversos parâmetros do parque residencial, possibilitando também uma análise combinada de vários desses parâmetros. O programa a desenvolver pretende atribuir um certo nível de rapidez na obtenção de resultados através da automatização dos processos de análise. Através desta caracterização será possível comparar as variáveis em função da região ou do ano de construção, assim como a avaliação do impacto de medidas de política energética, o progresso realizado na área de certificação energética ou a disparidade regional da certificação energética. A metodologia implementada baseia-se essencialmente no modelo de análise e caracterização estatística. Este modelo está a ser desenvolvido no software MATLAB. A parte em foco nesta primeira abordagem ao trabalho foi o código desenvolvido, sendo que toda a análise será aprofundada numa segunda parte do trabalho. Os dados relativos ao Sistema de Certificação Energética fornecidos pela ADENE – Agência para a Energia estão organizados em ficheiros de informação diferenciada, com a informação de cada entrada correspondente a um certificado energético, divididos em ‘Geral’ e ‘Envolvente’. Contêm uma série de informações sobre o certificado de cada uma das habitações, relacionados com a localização do mesmo, características estruturais, zona climática, necessidades de energia e índices de desempenho. O tratamento destes dados pelo modelo computacional desenvolvido veio a mostrar ao longo da sua elaboração uma panóplia de resultados, que foram utilizados para responder a perguntas colocadas. O parâmetro sobre o qual recaía cada pergunta foi inicialmente caracterizado num âmbito nacional, de modo a aferir sem distinção de contexto (novo, existente ou grande intervenção), ano de construção ou região NUTS III e que constituem os três tipos de filtros disponíveis. Após o enquadramento foi possível observar, através da análise por variável, a disparidade entre ambientes urbanos e rurais no qual é destacada a área útil do pavimento, sendo que esta é como seria de esperar maior em regiões tipicamente rurais. A surpresa está na área de pavimento útil que para o ‘Algarve’ e a ‘Grande Lisboa’ uma distribuição de probabilidade equiparável, apesar de uma muito maior densidade de alojamentos em ‘Grande Lisboa’. Foi possível observar através do ano de construção e contexto o impacto nos indicadores de desempenho energético que a alteração da Legislação foi tendo ao longo dos anos, como é o caso da transmitância térmica das janelas e do coeficiente global de desempenho energético, mostrando a forte contribuição para um melhor desempenho energético do edificado português.
The global energy demand is partially due to the energy demand in the residential sector, which represents 30%. Part of this energy demand in residential buildings is related to heating and cooling systems, so the user can achieve conditions for thermal comfort. The quantification and characterization of the energy consumption in a building stock can be used as information to predict consumption behavior, to map energy poverty, usage scenarios and as impact study for energy policies. The Residential Building Stock in Portugal has not been deeply characterized yet, so a computational model, which provides a rapid and easy study of the database available to the date could potentially be helpful to identify construction and energy related patterns. To address the need for characterization and analysis, a computational tool was built using MATLAB. This tool arrangement and data treatment requirement will be further explained so it can be modified if needed. The data is part of the Portuguese Energy Performance Certification, which first implementation dates from 2006, proceeded by an update, in 2013. The questions one can analyze about the Residential Building Stock are extensive, therefore the most pertinent questions will be answered during this work, as to understand the evolution of the Residential Building Stock in time and space, using this analyzing tool. Every question studied had its national sample characterized to frame it. The answers to the questions showed that energy performance related parameters, Energy Certification Coefficient improved over the periods, in particular the periods when a regulation was introduced or updated. This proves that energy performance regulations had a positive effect on the Residential Building Stock towards the concept of nearly-zero energy buildings (NZEB) on private households in 2020.

Esta dissertação tem como principal objetivo analisar as principais diferenças entre a regulamentação atual prevista para as frações habitacionais (REH) e a regulamentação anterior (RCCTE), de forma a avaliar qual o impacte das alterações na metodologia de cálculo e na classificação de desempenho energético. A motivação para a realização deste trabalho deve-se ao facto de há vários anos na minha vida profissional proceder à realização de estudos de desempenho térmico de edifícios, emissão de certificados e pré-certificados.
In August 2013, with the publication of Decree-Law 118/2013, the National Energy Performance Certification System and Indoor Air Quality in Buildings (SCE – Decree-Law 78/2006); the Regulation of Temperature Control Systems in Buildings (RSECE – Decree-Law 79/2006) and the Regulation of Thermal Behaviour Characteristics in Buildings (RCCTE – Decree-Law 80/2006) were revised. Decree-Law 118/2013 of 20th August, approved the System for Energy Certification of Buildings (SCE), which integrates the Regulation on the Energy Performance of Residential Buildings (REH) and the Regulation on the Energy Performance of Services Buildings (RECS). The new regulations introduced changes in the applicability, organization, systematization and methodology. This document aims to analyse the differences between the current regulations provided for houses (REH) and the previous regulations (RCCTE) in order to study what are the main changes in the calculation methodology and energy performance rating. The motivation for this work is based on energy certificates to existing and new buildings that I have made in the last years of my professional life.

Abstract:
Internal heat gains from occupants, equipment and lighting contribute a significant proportion of the heat gains in an office space. Usage of ICT in offices is growing; on the other hand, their efficiency is also improving all the time. Increasing energy efficiency in buildings have led to the situation, when new, well insulated office buildings, with high internal gains within the working hours may cover low heating energy demand. Such buildings, even in heating dominated countries, such as Lithuania, often also suffer from overheating during the winter heating season. The paper presents the analysis of energy demand of the office building for various plug loads (ICT equipment) internal gains scenarios and demonstrates its influence on buildings energy performance. Simulation results enable to conclude, that when assessing sustainability and energy bills of the building, plug loads play a very important role. Meanwhile, assessing just energy performance influence is very small. Energy performance certification results show, that plug loads may influence energy performance label just for buildings corresponding A+ and A++ labels).

Abstract:
The Earth is faced to decreasing of energy resources due to increasing of energy consumption. This reason accelerates the global warming which leads the Earth to a place in which quality of life is reducing year by year. A considerable portion of total energy consumption is used in residential sector in the world. The usage of energy in residential sector effectively ensures large amount of energy saving. Nowadays, the buildings have been aiming to design which consume low energy and supply high comfort. In order to design energy efficient buildings, all the designing parameters which include passive systems must be taken into consideration together considering versatile interior and exterior conditions. In this study the energy efficient building was described and the applications were explained for the sample building. The office building designed to obtain LEED certification was taken into consideration as a current application in Turkey and it was modeled using TRNSYS simulation program during the year. The heating and cooling loads were calculated. According to results some suggestions were recommended for reducing the heating and cooling demands of the office building and any suggestion was simulated and analyzed for the designed building.

Abstract:
Building energy performance regulations and standards around the world are evolving aiming to reduce the energy use in buildings. As we move towards zero energy buildings, the embodied energy of construction materials and energy systems becomes more important, as it represents a high percentage of the overall life cycle energy use of a building. However, this issue is still ignored by many regulations and certification methods, as happens with the European Energy Performance of Buildings Directive (EPBD), which focuses on the energy used in operation. This paper analyses a typical house designed to comply with Irish building regulations, calculating its energy use for heating and how water with the Irish national calculation tool, which uses a methodology in line with the EPBD. A range of measures to reduce the energy performance in use of this typical house are proposed, calculating the reduced energy demand and moving towards a zero energy demand building. A life-cycle approach is added to the analysis, taking into account the differential embodied energy of the implemented measures in relation to the typical house base-case, annualizing the differential embodied energy and re-calculating the overall energy use. The paper discusses how a simplified approach for accounting embodied energy of materials could be useful in a goal to achieve the lowest life-cycle energy use in buildings, and concludes with a note on how accounting for embodied energy is a key element when moving towards zero energy buildings.

Abstract:
The developing communities in their path for rapid development is endeavoring to make all necessary and appropriate measures to enhance the efficiency of energy utilization and increase the beneficiation of the energy resources. The energy production, transmission, distribution and utilization efficiency becomes a vital factor and measure of national development. Governmental organizations were established earlier to be responsible for energy planning and efficient utilization, information dissemination and capacity building as well as devising the necessary codes and standards. Throughout the Nation, energy resources are widely used and consumption rates are in general exceeding the International accepted values. Energy rationalization and audit exercises were developed and monitored by Governmental Authorities, Universities and Research centers through the past two decades with a definitive positive energy reduction and beneficiation. The development of the relevant codes for Residential and Commercial Energy Efficiency in buildings is underway through the governmental bodies responsible for the research and development in the building Technology sector and is the umbrella under which the National and Unified Arab Codes are developed and issued. A proposed new Energy Performance in Buildings Directive (EPBD) would fulfill the following main targets of energy performance directive: 1. “Legestilative authorities shall ensure that, when buildings are constructed, sold or rented out, an energy performance certificate is made available to the owner or by the owner to the prospective buyer or tenant, as the case might be. … 2. The energy performance certificate for buildings shall include reference values such as currant legal standards and benchmarks in order to make it possible for consumers to compare and assess the energy performance of the building. The certificate shall be accompanied by recommendations for cost-effective improvement of the energy performance…” The following steps shall be required for the energy certification: 1. Develop methodologies for energy declaration of the buildings. 2. Develop reference values (key numbers) and /or systems for benchmarking. 3. Provide a labeling system for selected buildings. 4. Describe an energy signature for the building.

Abstract:
The way that buildings are designed and constructed today has a negative impact on building energy consumption. Facade components are essential in determining the building energy demand during the operational phase. This paper aims to investigate what role the building façade plays in improving the energy efficiency of a low rise office buildings in a Mediterranean climate. Verification of the façade energy performance for one of the Eastern Mediterranean University buildings in Northern Cyprus, namely Rector’s Office Building is the second phase of the study. To conduct the present study, a literature review is used, as well as, an analyze for a group of contemporary low rise office buildings with LEED certification from the Mediterranean climatic zone is achieved to attain the investigation and to set the verification checklist. The study has established the important role that building facade can play to reduce the annual building demand for energy in the Mediterranean low rise office buildings through a set of strategies. Different techniques were used to apply these strategies. According to the verification, the study revealed an attempt to achieve an energy efficient building through the façade design by using specific techniques. Some suggestions have been recommended in order to improve the facade energy performance for this type of buildings.

Abstract:
This paper presents a comparison of concept stage computational model predictions to capture how building energy consumption is affected by different climate zones. The California State University, Fullerton (CSUF) Student Housing Phase III, which received a Platinum Leadership in Energy and Environmental Design (LEED) certification for the Building Design and Construction category, and its performance in a LEED California Nonresidential Title 24 (NRT24) and ASHRAE 90.1 climate zones is used as a case study to illustrate the method. Through LEED approved simulation software, the standard compliant energy simulation models are compared to the occupancy scheduled models along with the actual energy consumption in different climate zones. The results provide insight to how variables within student dormitory life affect total building energy usage. Total amount of energy consumed per area is one new factor providing understanding into occupancy trends. This new data set reveals more understanding regarding how and where the energy is consumed to maintain a comfortable learning environment.

Abstract:
As an increasing number of buildings aspire to significant energy reduction and higher Leadership in Energy and Environmental Design (LEED®) certifications, it is clear that non-regulated process loads are the single greatest remaining opportunity in high performance design. Historically outside the purview of state and national energy design standards, the performance of transformers, elevators, escalators, process systems, and consumer information technology underscore a significant challenge and rising opportunity. This paper examines the impact of non-regulated loads on high performance buildings, ranging from first cost to energy performance and occupant behavior.

Full text
Abstract:
Municipal solid waste from Lee County and Hendry County is processed at the Lee County Solid Waste Resource Recovery Facility (the “Facility”). Lee County (the “County”) owns the Facility, which began commercial operation in December 1994. The Facility’s current permitted capacity is 1,320 tons per day (tpd), provided by two 660-tpd boiler units, at a reference waste of 5,000 Btu. Covanta Energy of Lee, Inc. operates and maintains the Facility under the terms of a Service Agreement with the County that runs through 2014. Covanta also designed and constructed the Facility. The expansion of this Facility will be the first new construction of a municipal waste combustion (MWC) unit since the New Source Performance Standards were adopted. Despite the County’s comprehensive recycling program, the amount of solid waste the County delivers to the Facility has increased each year since the Facility began operation, primarily due to population growth. In 1999, this amount reached the Facility’s guaranteed annual capacity of 372,300 tons. In 2000, the Facility processed over 392,000 tons of municipal solid waste, while the County landfilled nearly 44,000 additional tons of processible waste. Current population projections for Lee and Hendry Counties suggest that processible solid waste generation will continue to increase, reaching nearly 550,000 tons by 2010. Rather than landfilling processible waste generated in excess of the Facility’s current capacity, it is the County’s intention to expand the Facility by adding a third 660-tpd boiler unit which would increase the Facility’s permitted capacity to 1,980-tpd. The original application for the Facility’s Power Plant Site Certification anticipated such an expansion, including provisions for a third 660-tpd MWC unit. Certain provisions for this third unit were incorporated into the Facility’s design and construction as well. These included providing the physical space for the third unit, the physical space for an additional flue for the third unit, and sizing the tipping floor, refuse pit, and certain common equipment for three units. The expansion will require a second turbine-generator unit and expanded switchyard, an extension to the existing turbine-generator building, as well as the addition of a third boiler unit and air pollution control equipment. The expansion will also require modifications to certain equipment and systems common to all boiler units in order to meet the additional capacity requirements of the expanded Facility. As of February 2003, the County is waiting for the Florida Department of Environmental Protection to issue a draft PSD Air Permit and is on scheduled to go before the Power Plant Siting Board in September 2003.

Abstract:
Commercially available photovoltaic (PV) modules and systems often fall short of meeting the performance ratings specified by the module manufacturers or system designers [1]. This has resulted in reduced performance and low system availability, some system failures, and generally, a lack of confidence by systems users. Hence, a need for an independent accredited laboratory to conduct the testing and certification of PV modules and systems has been indicated by the PV industry, electric utilities, and other system users and owners. To meet this industry and user need, the Florida Solar Energy Center (FSEC) has started a PV testing and certification program. The FSEC PV testing laboratory and certification program have been accredited by the American Association for Laboratory Accreditation (A2LA) and approved by the PowerMark Corporation (PMC, www.powermark.org ), which is the certification body of the PV industry in the United States. The FSEC program currently covers three areas: (i) PV module power rating certification, (ii) Stand-Alone PV system performance evaluation and certification, and (iii) Grid-Connected PV system design review and approval. The PV module power rating certification is central to these three areas of the FSEC program, as illustrated in Figure 1. The details of the FSEC PV testing laboratory accreditation and certification program are described in a previous paper [2].

Abstract:
The aerospace industry is beginning to grapple with the reality of certifying electric aircraft (EA), signaling the maturing of the field. Many players are ramping up their activities to respond to imminent technical, safety, and regulatory requirements. While there are gaps in EA knowledge as well as the processes for certifying them, some leading standards development organizations (SDOs) such as SAE International, ASTM International, and RTCA—ably supported by representatives from regulatory agencies—are stepping in to address many of these issues. Of special importance are the new rule changes in the normal category (14 CFR Part 23, Amendment 64) that shift from a prescriptive philosophy to “performance-based rules.” Regarding system knowledge, there has been a trend in the use electrical energy to power systems that have long employed mechanical hydraulics. In the new EA paradigm, these components will be employed at criticality levels not previously witnessed in conventional aircraft, calling for a specific set of certification demands. Unsettled Issues Regarding the Certification of Electric Aircraft tackles the certification challenges faced by EA manufacturers in both the small (normal) and large (transport) categories, addressing technical, business, and process issues.
