Introduction Key design features of high performance houses are investigated for improving energy efficiency in cold climates. Referencedwellings with typical constructions and system designs are compared with high performance houses using the best technology available . Greenhouse heating applications have an important effect on yield, quality, and the cultivation time of products. Solar energy is an attractive substitute for conventional fuels for passive solar agricultural greenhouses and active heating of greenhouses. The solar greenhouse has been designed in order to reduce heat losses and increase useful solar gains on a daily and seasonal basis. Solar thermal energy can be stored as sensible heat, latent heat, heat of reaction, or a combination of these. In most storage systems, it is stored as sensible heat in materials such as water and rocks. In latent heat storage systems, the latent heat accompanying a phase change material is used for thermal energy storage. Most of the greenhouse heating demand can be supplied by latent heat st
