1. Influences from Building Energy Efficiency Refurbishment on a Regional District Heating System
Sammanfattning : Improving energy performance of existing buildings is an important part in decreasing energy use and in turn reduce the greenhouse gas emissions caused by human activity and the primary energy use.To be able to evaluate how energy refurbishment influences the greenhouse gas emissions and the primary energy use a wider system perspective is needed that puts the building in its context.

2. Building Energy Efficiency Measures in District Heating Systems
Sammanfattning : Improving energy performance of existing buildings is an important part in decreasing energy use and in turn reducing greenhouse gas emissions and primary energy use. To be able to evaluate how energy refurbishment influences greenhouse gas emissions and primary energy use a wider system perspective is needed which puts the building in its context. LÄS MER
3. Energy efficiency measures in the built environment - some aspects to consider in Sweden
Sammanfattning : The traditional energy system as we know it today will change in the future. There is a worldwide concern about the global warming situation and there are different actions implemented to limit the consequences from, mainly, the use of fossil fuels. LÄS MER
4. Life cycle assessment and life cycle cost analysis of a single-family house
Sammanfattning : The building industry is responsible for 35% of final energy use and 38% of CO2 emissions at a global level. The European Union aims to reduce CO2 emissions in the building industry by up to 90% by the year 2050. Therefore, it is important to consider the environmental impacts buildings have. LÄS MER
5. Life-Cycle Energy and Carbon Implications of Wood-Based Products and Construction
Sammanfattning : Forests can be an important element of an overall strategy to limit the atmospheric concentration of carbon dioxide (CO2) that contributes to climate change. As an integral part of the global carbon cycle, forests remove CO2 from the atmosphere as they grow, and accumulate carbon in tree biomass. LÄS MER
