Residential and commercial buildings accounted for about 68% of the total U.S. electricity consumption in 2002. Improving the energy efficiency of buildings can save energy, reduce cost, and protect the global environment. In this research, artificial neural network is employed to model and predict the facility power usage of campus buildings. The prediction is based on the building power usage...

Forced air distribution systems can have a significant impact on the energy consumed in residences. It is common practice in U.S. residential buildings to place such duct systems outside the conditioned space. This results in the loss of energy by leakage and conduction to the surroundings. In order to estimate the magnitudes of these losses, 24 houses in the Sacramento, California, area were t...

High demand for housing and land scarcity in the town area has increased provision of High-rise Residential Buildings (HrRB). HrRB different owners but shares same common facilities. Its facilities are generally prone to damages either from

Solar shading designs are important for reduction of building energy consumption and improvement of indoor thermal environment. This paper carried out a number of building simulations for evaluation of the energy performance of different shading devices based on incremental costs. The results show that movable shading devices lower incremental costs by up to 50% compared with fixed ones for the...

In order to maintain good performance and a timeefficient calculation period to simulate an entire urban environment, the simulation efforts for single buildings must be as simple as possible. By generalizing all heating load curves using particular density functions, the result is a heating density function for non-residential buildings considering particular constructions and individual occup...

To investigate the energy performance of solar shading devices, this paper carried out a survey on the current status of solar shading utilization in buildings in Ningbo and performed building simulations to evaluate the energy savings potential by adopting different solar shading devices. Results show that solar shading utilization in this area is not popular and effective, and should be consi...

reducing energy consumption and greenhouse gas emissions have become a worldwide necessity. iran has the sixteenth ranking position of global greenhouse gas emissions and its rate of growth is above global average. built environments are responsible for about 40% of energy consumption and it is generally approved that the greatest portion of built environment is dedicated to residential land us...

With the urbanization process of the hot summer and cold winter (HSCW) zone in China, the energy consumption of space and water heating in urban residential buildings of the HSCW zone has increased rapidly. This study presents the energy efficiency and sustainability evaluation of various ways of space and water heating taking 10 typical cities in the HSCW zone as research cases. Two indicators...

Abstract The US government has set a target of reducing CO2 emissions by 20% below the 2005 targets by the year 2020. Literature review reveals that residential buildings contribute over 20% of the total emissions mainly used for space heating, cooling, water heating and lighting. In hot humid climates, the concern is mainly for cooling and hot water that account for over 50% of the total resid...

this paper deals with evaluating the thermal behavior of exterior walls in dwellings of a particular place. today, there is a huge increase in constructing multi-storey apartment buildings and single-family houses in the city of yazd, a city with hot dry climate and a rich historical architecture in iran. unfortunately, the new methods that are used nowadays to make the envelopes of these dwell...
