The building sector accumulates approximately a third of the final energy consumption. Consequently, the improvement of the energy efficiency in buildings has become an essential instrument in the energy policies to ensure the energy supply in the mid to long term moreover is the most cost-effective strategy available for reducing carbon dioxide emissions This paper is studying the main objecti...

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 ...

The living standard of Chinese residents greatly improved during China's current economic development. However, residential building energy consumption has also grown quickly. Therefore, it is critical to carry out building energy conservation in residential premises to ensure both building comfort and controlled energy consumption. Digital technology, an effective tool, could help designers co...

Building information modeling can help in predicting the energy efficiency in future based on dynamic patterns obtained by visualization of data. The aim of this study was to investigate the effective parameters of energy consumption using BIM technology which can evaluate the buildings energy performance. First, three forms of general states in the building were modeled to evaluate the propose...
