Eco-Bat: A design tool for assessing environmental impacts of buildings and equipment

This paper presents the features of Eco-Bat, a computer program developed to assess the environmental impacts of buildings, including construction materials and energy consumed, during its life cycle. The methodology used to evaluate environmental impacts based on a life cycle assessment (LCA) approach, compatible with ISO 14040 standards, is detailed. The data are mainly extracted from an environmental impacts database, Ecoinvent, which contains values for the manufacturing and elimination of numerous materials as well as other processes. Two applications are presented to illustrate the possibilities offered by Eco-Bat. The first one is a comparison of different variants of building facades. The second example shows the analysis of a whole building including its energy consumptio

IMPROVE ::enhancing demand-side energy reduction through informative billing strategies

In Switzerland, most of the information available on the energy bills corresponds to the minimum legal requirements imposed by national regulations. Such a scarcely understandable information does not motivate consumers to reflect on their level of energy consumption. A more user-friendly information presentation on the energy bill may induce increased awareness, laying the grounds for behaviour changes required to achieve the goals of the Energy Strategy 2050 of the Swiss Federal Council. The aim of the IMPROVE project was to explore how both consumers and energy utilities evaluate and perceive the importance of introducing enriched information on the energy bill to encourage households to reconsider their energy consumption levels

Methodology for cost-effective energy and carbon emissions optimization in building renovation (Annex 56): methodology and assessment of renovation measures by parametric calculations

Buildings are responsible for a major share of energy use and have accordingly been a special target in the global actions for climate change mitigation, with measures that aim at improving their energy efficiency, reduce carbon emissions and increase renewable energy use. IEA-EBC project «Cost-Effective Energy and Carbon Emissions Optimization in Building Renovation» intends to develop a calculation basis for future standards, which aim at maximum effects on reducing carbon emissions and primary energy use. Thereby, the project pays special attention to the renovation of existing residential buildings and to cost effective building renovatio

Methodology for cost-effective energy and carbon emissions optimization in building renovation (Annex 56)

"Energy in Buildings and Communities Programme, March 2017"Buildings are responsible for a major share of energy use and have been a special target in the global actions for climate change mitigation, with measures that aim at improving their energy efficiency, reduce carbon emissions and increase renewable energy use. The IEA-EBC Annex 56 project «Cost-Effective Energy and Carbon Emissions Optimization in Building Renovation» intends to develop the basics for future standards, which aim at maximizing effects on reducing carbon emissions and primary energy use while taking into account the cost-effectiveness of related measures. The IEA EBC Annex 56 project pays special attention to cost effective energy related renovation of existing residential buildings and low-tech office buildings (without air conditioning systems).info:eu-repo/semantics/publishedVersio
