The purpose of this paper is to introduce Energy Smart Tool, a new web-based building energyperformance benchmarking system developed recently by Energy Sustainability Unit of NationalUniversity of Singapore. It provides users with direct comparisons of their buildings energyperformance to other similar facilities, which helps to identify the position their facilities, and to setenergy saving targets. A general discussion of the benchmarking procedure is given.

The goal of this study, carried out on a wooden building, is to apply the methodology of identification inorder to obtain the physical parameters which characterize the thermal behaviour of the building. Theidentification of the system is the methodology of modeling the system starting from the experimentaldata.

As in other parts of the world, building legislation has been used since the 1980s by governmentbodies in the Arabian Gulf countries. These countries sought to reduce rising electrical consumption(6.7% per year) during the construction boom following the discovery of oil. Generally, however, theseearly regulations are limited in scope and have been implemented in a piecemeal manner across thedifferent countries.

In 1997 several countries ratified the Kyoto protocol and so engage themselves to take into accountthe global warming, promote the sustainable development and act in order to reduce emission ofgreenhouse gases. Within this context, energy in buildings is known to be one of the first greenhousegases emitting sector. Consequently, determination of steady-state thermal transmission properties foreach kind of faade components becomes necessary in order to evaluate accurately energy loss, todevelop and enhance new products.

The paper describes the transfer of technology appropriated from the social, economical andenvironmental point of view in schools at the province of Mendoza (South latitude 32, 53, Westlongitude 68 51, semi-arid climate) placed at the Southwest region of Argentina. The main aim of theinvestigation is to develop technologies which allow the maximum autonomy in terms of heating andlighting of the school buildings trough the use of solar energy.

This paper presents the energy and economic analysis used to determine cost effective requirementslevels to the thermal standard for buildings in Lebanon. The heating and cooling energy use fordifferent buildings types (18 buildings) according to the variation of envelop parameters was simulatedfor realistic cooling and heating schedules and five Lebanese climatic zones. Parameters investigatedincluded, construction type, insulation levels, window sizes and solar protection. The energysimulation program VISUAL-DOE.3 was used for the energy use simulations.

This paper focuses on energy performance compliance checks to the French EP-regulation RT 2000 and the way they are performed in Rhône-Alpes, Burgundy, and Franche-Comté. It gives an overview of the approach developed and used which consists in collecting

In March 2003 a “CO2 - Saving Potential when using Pipe Insulation” study [1], sponsored by Armacell - worldwide producer of flexible pipe insulation products, was published by the Centre for Environmentally Sustainable Buildings (ZUB) in Kassel. The aim

The present paper presents the results of the application of cluster analysis in the energy rating ofschool buildings. A complete program on energy and environmental quality of school buildings wasundertaken by NKUA in collaboration with the School Authority of Greece. The research was based onthe participation of 320 schools of secondary education from all the prefectures of Greece.

The mitigation of the heat island effect can be achieved by the use of cool materials that arecharacterized by high solar reflectance and infrared emittance values. Several types of cool coatings,both commercially available and prototype ones have been tested. Their spectral reflectance, infraredemittance and surface temperature measurements reveal that these materials can be classified ascool materials with the ability to maintain lower surface temperatures. Cool materials can be used onbuildings (roofs and walls) and other surfaces of the urban environment.
