The external walls are regarded as an important source for the thermal exchange between the outside and inside of a building. Despite the significance of building walls for energy savings, a large body of research has focused mainly on thermal comfort, environmental impacts, and economic costs of residential buildings. However, few researchers have addressed the thermal performance of common bu...

introduction reducing and optimizing energy consumption and consequently environmental pollution reductions, besides improving building performance providing occupants comfort conditions, make the building's concept closer to the concept of green building and sustainability. once the decision to build green has been made, one of the first steps in the green design process is to establish f...

in this research multiple-regression analysis with stepwise selection method was employed for investigating the effectof vertical building envelopes solar radiation (evr) on cooling energy consumption (e cooling) in residential sector.the high capacity of solar energy in semi-arid climate (shiraz) can provide a part of buildings required energy. dependson house orientations in two directions of...

In some climates, massive buildings made of stone, masonry, concrete, earth and … can be utilized as one of the simplest and most effective ways of reducing building heating and cooling loads. Very often such savings could be achieved in the design stage of the building and with a relatively low-cost. Such declines in building envelope heat losses combined with optimized material configurati...

nowadays, one of the greatest energy consumption sources in the world is recognized as hvac systems, which are used vastly not only for industrial productions but also for creating comfort condition in dwellings. since beginning of warm or cold season, we will need a source of energy to reach desirable thermal conditions inside a building. also, earth is naturally a great thermal source, which ...
