  • Analysis of buildings' energy consumption by means of exergy method

    Among the objectives of the Directive 2002/91/EC and of the Council "Energy performance of buildings", Energy Performance of Building Directive (EPBD) the energy certification of buildings represents a fundamental role. The method here described starts from the LowEX tool, previously developed in the IEA ECBCS Annex 37 framework. By using the exergy approach, new (non-economic) indices could be ...

  • Exergy analysis combined with LCA for building envelope energy efficiency retrofit

    This article presents a kind of exergy analysis combined with LCA to evaluate the building envelope energy efficiency retrofit. A typical case in Ningbo city of China is analysed. The results show that it takes 15 years for the cumulative saved energy consumption in the use stage to equal the embodied energy of the newly added insulation materials in the product stage. Yet, it is impossible that ...

  • Life Cycle Analysis of Hazardous Waste from the Energy Conservation Measures in Existing Buildings

    AbstractThe budget used for the retrofitting of low energy efficiency equipment in building is normally paid by financially considering the internal rate of return and a simple payback period. The environmental view has not been considered typically. One of the overlooked aspects within the energy conservation measures is the managerial cost of hazardous waste from the removed low energy ...


  • LIFE CYCLE ANALYSIS OF HAZARDOUS WASTE FROM THE ENERGY CONSERVATION MEASURES IN EXISTING BUILDINGS: LIFE CYCLE COST EFFECT

    Abstract The budget used for the retrofitting of low energy efficiency equipment in buildings is normally paid after financially considering the internal rate of return and a simple payback period. The environmental view has not been considered typically. One of the overlooked aspects within the energy conservation measures is the managerial cost of hazardous waste from the removed low energy ...


  • A comparative analysis of building materials for sustainable construction with emphasis on CO2 reduction

    Building contributes almost 40% of CO2 emissions and is a major contributor to the green house gas (GHG) emissions. Different types of construction materials possess a wide variation of embodied energy and emit CO2 at different magnitudes during its life cycle. Selection of appropriate construction materials can considerably cut down ...

  • Benchmarking of low 'exergy' buildings

    An optimisation of the exergy flows in buildings and the supply structures related to them, similar to other thermodynamic systems, can help in identifying the potential of increased efficiency in energy utilisation. The low exergy (LowEx) approach entails matching the quality levels of exergy supply and demand to streamline the utilisation of high–value energy resources. This approach is the key ...

  • Exergy indicators in the building environment

    The objective of this work is the application of the exergy analysis to the building sector and the introduction of suitable exergy indicators. The indicators are tools which are representative of the system under study and provide reliability over time, information to policy makers and awareness of potential environmental problems arising from human activities. The application of the exergy ...

    Client: Upscale Custom Home Builder  Location: Florida Gulf Coast  Completion: Sept thru Oct 2007  Corrections Cost: ~$25,000 Key Project Team: Timothy Toburen Indoor Environmental Technologies (IET) was retained by the builder to determine the cause of excessive sweating ...

  • Energy, exergy, thermoeconomic and sustainability analyses of a building heating system with a combi–boiler

    The energy, exergy, thermoeconomic and sustainability analyses are applied to the building heating system with a natural gas–fired combi–boiler. The building area is considered as 90 m². Furthermore, the design and analysis of the natural gas installation of the building are done. Two different methodologies (Fine–HVAC and LowEx analyses) are used for energy analyses (heat loss and demand) of the ...
