In this research, an analytical method for quantification of the thermal energy performance improvement for a building integrated photovoltaic double-skin façade has provided. The system has been suggested as a retrofit measure for an existing building in Tehran. The effect of thermal performance has been analyzed through computer-assisted developed code using engineering equation solver softwa...

Energy costs are notoriously uncertain but what is the effect of this on energysaving investments? We find that real-option frictions imply a novel equilibrium response to increasing but uncertain energy costs: early investments are cautious but ultimately real-option frictions endogenously vanish, and the activity affected by higher energy costs fully recovers. We use electricity market data f...

Taking the provincial capital, labor and energy as inputs, regional GDP as output from 1995 to 2007, the paper quantifies the vertical and lateral energy saving potential by introducing the radial adjustment and slack adjustment of DEA. The results show that by the vertical, the achievement of energy saving in 2007 is better than their respective historical performances. By horizontal, in 2007 ...

Escalators are a common method of transportation for people in commercial and residential buildings, for this reason its energy efficiency is usually a matter of concern. Typically, the design of energy saving systems to be used in them involves the control of their speed. In this situation, in order to estimate the achievable energy savings it is necessary to evaluate the escalator’s behaviour...

Finally, applies the above theory to the design of energy saving control system in X company’s office...

Design for sustainable behavior has become more important for product or service design considering environmental sustainability in the use stage. The goal of this work is to specifically help design for encouraging energy-saving behavior in selecting effective persuasive design strategies and game design elements by considering users’ differences. The work begins with screening commonly employ...

In order to reduce building energy consumption and make wall insulation materials meet fire protection requirements, the authors put forward a kind of saving model exterior under green nanomaterials. Mainly using PBECA calculation software. By setting up multi-component, multi-material method. The aggregate in light device modified by nanomaterials is simulated analyzed, agent area compared. ef...

China is one of the major energy-consuming and carbon-emitting countries. Promotion of efficient energy use is crucial in reducing energy consumption and carbon emission. Under external pressure and realizing the importance of energy conservation, many firms have adopted measures to save energy. Such measures entail active employee participation. However, employees often lack motivation and thu...

The exergetic analysis is a tool that has been used successfully in many studies aiming a more rational energy consumption to reduce the cost of processes. With this analysis, it is possible to perform an evaluation of the overall process, locating and quantifying the degradation of exergy. This paper applies exergy approach for analyzing the heat exchanger network design and refrigeration of M...

One of the most important methods of saving energy and providing indoor comfort conditions of buildings is the careful design of the façades. A “double skin glass façade” is optimally one of the best options that control the heat interaction between indoor and outdoor spaces. Two kinds of heating energy is usually transmitted through exterior envelope “conduction” and “radiation”. Double skin g...
