1. Energy Savings Using a Direct Current Distribution Network in a PV and Battery Equipped Residential Building
Sammanfattning : Energy from solar photovoltaic (PV) are generated as direct current (DC) and almost all of today’s electrical loads in residential buildings, household appliances and HVAC system (Heating Ventilation and Air-conditioning) are operated on DC. For a conventional alternating current (AC) distribution system this requires the need for multiple conversion steps before the final user-stage. LÄS MER
2. Heat demand profiles of buildings' energy conservation measures and their impact on renewable and resource efficient district heating systems
Sammanfattning : Increased energy performance of the building stock of European Union is seen as an important measure towards mitigating climate change, increasing resource utilisation efficiency and energy supply security. Whether to improve the supply-side, the demand-side or both is an open issue. LÄS MER
3. The Non-Energy Benefits of Industrial Energy Efficiency : Investments and Measures
Sammanfattning : Improved industrial energy efficiency is viewed as an important means in the reduction of CO2 emissions and climate change mitigation. Various energy efficiency measures for improving energy efficiency exists, but even evaluated as cost-effective, there seems to be a difference between the energy efficiency measures that theoretically could be undertaken and which measures that actually are realised.

4. A Policy Analytical Approach of Assessing Energy Efficiency Standards and Labeling for Appliances
Sammanfattning : China is the world’s largest producer and consumer of household appliances, lighting and commercial equipment. China first adopted Minimum Energy Performance Standards (MEPS) in 1989. LÄS MER
5. The open absorption system : energy savings in different applications
Sammanfattning : The open absorption system is a technique that makes it possible to recover energy in different processes using moist air. In most applications the latent heat in moist air is difficult to recover because of the low temperature. Processes using outdoor air to carry away moisture therefore have high energy demands. LÄS MER
