One of the key methods to improve the energy saving performance of a building is to apply advanced materials or components to the building envelope. However, the two parts of a building’s envelope, the transparent one and the non-transparent one, are usually investigated individually by...

The performance of a kind of shape-stabilized phase change material (PCM) was demonstrated in the Testing and Demonstration Platform for Building Energy Research. The results indicate that the use of PCM could lower the indoor temperature fluctuation and slow the indoor temperature’s decline...

The first Romanian passive office building has been constructed by the AMVIC Company in Bragadiru, 10 km south of Bucharest. The overheating rate and the cooling load are higher for a passive building than for a standard building. The internal heat sources and the maximum allowed indoor...

Latent heat thermal energy storage (LHTES) integrated active free cooling stores night time cold and serves as heat sink for cooling when demand rises. Passive buildings, albeit their advantages in limiting heat loss during winter time, are often paired with excessive internal overheating in...

A passive house is a cost-efficient building that can manage throughout the heating period, due to its specific construction design, with more than ten times less heat energy than the same building designed to standards presently applicable across Europe. This paper describes the thermal...
