Better energy management will result in substantial savings in the operating costs of facilities especially in the case of large building portfolios such as university campuses. Continuous energy management relies on a seamless energy performance evaluation process. But even then, it is hard to find an established and objective method for energy performance evaluation. The objective of this pap...

Significant amounts of energy are consumed in the commercial building sector, resulting in various adverse environmental issues. To reduce energy consumption and improve energy efficiency in commercial buildings, it is necessary to develop effective methods for analyzing building energy use. In this study, we propose a data cube model combined with association rule mining for more flexible and ...

in this paper, the electrical consumption of a research center building is derived of the bills, then with defining of fuzzy bus thermal coefficient objective function for heating, the amount of available heat selling to research center building consumer that is produced by biomass solar hybrid source is calculated. with the capacity determination of biomass solar hybrid source to provide therm...

Energy efficiency in office buildings for the tropical climate has been a subject of much discussion in the building industry. The Malaysia Energy Commission Sustainable Building, also known as the Diamond Building was built as the third Government Energy Efficient building after the Low Energy Office (LEO) and the Green Energy Office (GEO). It is located in Putrajaya, Malaysia which has a hot ...

Retrofitting measures in old buildings aimed at reducing energy usage have become important procedures meant to counteract the effects of climate change and greenhouse gas emissions. The aim this study is evaluate usage, thermal comfort, CO2 emissions an building by changing parameters such as orientation, shading systems, location, low film application, alternative supply form a geothermal hea...

The design of a building can provide the highest thermal comfort in the interior without any mechanical equipment and save energy to a large extent. The roof of a building is an important part for thermal loss. This research studies the thermal performance of 14 conventional roof structures in Tehran city by using designbuilder 4.5. It is found that the polystyrene block performs best compared ...
