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...

Residential and commercial buildings constitute one of the largest energy consumption sectors in industrialized countries. This paper introduces a flexible commissioning system for maximizing energy usage efficiency in large and complex buildings. The system exploits (i) a data management scheme that uses distributed wireless sensors networks for environmental monitoring, (ii) a data analysis f...

Existing buildings are responsible for more than 40% of the world’s total primary energy consumption. Current building management systems fail to reduce unnecessary energy consumption and preserve user comfort at the same time mainly because they are unable to cope with dynamic changes caused by user’s interaction with the environment. To cope with this dynamicity, we propose a software archite...

Recently, environmental issues have been the focus of much of the world’s attention. This has stimulated a response in many countries, which has led to a closer examination of energy conservation strategies for conventional fossil fuels. One way of reducing building energy consumption is to design buildings, which are more economical in their use of energy for: heating, lighting, cooling, venti...

Commercial buildings consume a significant amount of energy today and are slated to consume even more in the future. This consumption necessitates the use of carbon-producing fuels such as coal and natural gas, both of which have significant environmental impacts. While renewable energy sources remain promising, it is expected that most of the electricity generation will still use fossil fuels ...

buildings play an important role in the energy demand sector. due to the increase of environmentalconcerns and renewable energy sources restriction, lighting control systems will play an important role in the reductionof energy consumption of the lighting without impeding comfort goals. lighting control systems can control lightingconsumption according to the type of building, adequate luminanc...

The percent of energy consumed by plug load equipment in commercial buildings is on the rise. Research conducted in the past has included surveying plug load equipment, measuring plug load electricity consumption and equipment operating patterns, and studying plug load reduction solutions in office buildings, but plug load energy use across other building types is poorly understood. A universit...

Exploring changes of building energy consumption and its relationships with climate can provide basis for energy-saving and carbon emission reduction. Heating and cooling energy consumption of different types of buildings during 1981-2010 in Tianjin city, was simulated by using TRNSYS software. Daily or hourly extreme energy consumption was determined by percentile methods, and the climate impa...

In the wake of rising energy costs, there is a critical need for sustainable energy management of commercial and residential buildings. Buildings consume approximately 40% of total energy consumed in the US, and current methods to reduce this level of consumption include energy monitoring, smart sensing, and advanced integrated building control. However, the building industry has been slow to r...

Improving energy efficiency in buildings and promoting renewables are key objectives of European energy policies. Several technological measures are being developed to enhance the energy performance of buildings. Among these, geothermal systems present a huge potential to reduce energy consumption for mechanical ventilation and cooling, but their behavior depending on varying parameters, bounda...
