Compact Fluorescent Lightbulbs (CFL’s) use less energy than standard GLS lightbulbs, last longer, are widely available and cost less than ever before. They have also been issued free to households over a number of years through funding provided by the ECC

This paper describes the current Welsh housing stock with a view to assessing the range of existing propertiesin terms of age, construction type and the implicationsfor mechanical heating and cooling of spaces. This work forms part of a larger project that will also involve the development of a series of computer models based on these findings, as well as the design, installation and performance monitoring of a domestic scale solar absorptioncooling system.

This project refers to the study and analysis of a central region of the city of Heraklion in Crete and the proposal of an installation of a light metal construction, aiming at the improvement of comfort conditions of the users of the region.

Energy savings inside buildings require a comprehensivedesign approach to balance bioclimatic strategies with the use of active systems.A climatic responsive building aims to mediate externalagents both to reduce climate loads and to create a healthy and comfortable indoor environment.The sensitive approach to comfort gives nowadays more chances to implement passive strategies and especially the use of natural ventilation.The residential settlement in Pieve di Cento is made with a general Masterplan designed according to sustainableprinciples.

By the new General plan by 2025 in St.-Petersburg it is planned to construct 130 million ??. M of the real estate (for comparison: now in city nearby 140 million ??.). From them nearby 50 million ??. The m is allocatedunder apartment houses, 30 million ??. M - under objects of socially-business purpose (hospital, school, hotel and trading complexes). Besides it is supposed to reconstruct 25 million ??. M industrial ????????and to add to the city real estate 25-30 million more ??. M due to development of an engineering infrastructure.

Looking for the energy efficiency improvement of the buildings, some countries are developing programs for the new or existent buildings to be more efficient. In Brazil, the research is to meet a very recently quality stamp, that is taking care to reduce wastes from the governmental public domain. This article proposes the analysis between the ?glass and wall surface temperatures and increase of classrooms radiance temperature, at Campinas City So Paulo State. For this methodology is adopted the Artificial Neural Network to simulate the variables.

Nowadays in view of the growing expectation of qualityurban spaces, planners, architects and developers concern about urban microclimate in the process of urban development. Under this context, the concept of urban climatic map (UCMap) has been introduced. UCMap is a tool for translating climatic knowledge into urban planning process. It can help urban planning professionals to understand and evaluate the effect of urban climatic issues on planning decision.

Following the study by V H C Crisp and P J Littlefair (CIBS, 1984)1 on Average Daylight Factor Prediction, the arguments for the use of average daylight factor as a design criterion are reviewed in light of new experimentalassessments.

This paper describes some of the thinking behind the thermal comfort provisions of the new European StandardEN15251 (CEN: 2007) which deals with all aspects on the indoor environment. The paper will present the evidence on which its provisions are based (focusing on thermal comfort) and the advantages they present for those concerned to design buildings which use the minimumof energy.

In urban canyons where, apartment buildings can be beneficial in terms of their close proximity to offices, shops etc, causing less traffic congestion and pollution, saving fuel costs and bringing people in close proximity to city centres. At the same time trying to accommodate people in city centres, leads to the development of congested and confined narrow deep apartments which have to be mechanically ventilated and artificially lit. To reduce costs, in 1962 designers began building narrow structures with light curtain walls and thin frames to increase daylight and natural ventilation.
