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.

This study examines, by means of energy simulation softwares, the thermal behaviour of a real heavy masonrybuilding designed with a full application of bioclimaticstrategies, located in Mediterranean climate; the results are then compared with the performances of a twin building, which differs for one single feature, that is thermal mass.

The objective of this work is to demonstrate through a case study of a Shopping Centre in Portugal how daylighting and Passive Solar Strategies can be efficient in this kind of buildings, always characterized by large transparent areas and, in consequence, with enormous heat gains that cause overheating problems, especially in summer. Different strategies will be showed applied to a real case. The Shopping Centre in analysis has considered, since the first phase of the design process, natural ventilation, daylighting and others efficient strategies.

The solar cooling plant in the Rethymno village Hotel supplies cooling energy to the dinning room as well as it supplies hot water to its central Domestic Hot Water (DHW) network. The solar cooling system is based on an absorption type machine, LiBr/H2O, able to be generated at the level of 80oC, since it is of single effect. The favorable environmental impact of the installation is highly important since the oil displacement by the solar energy yields to high CO2 emissions reduction.

This paper describes major elements of the design of three low-energy solar homes in Canada. Two of these are part of a demonstration program. The major features of the houses are: 1. direct gain passive solar design that emphasizes utilization of distributed thermal mass in the south-facing part of the ground floor; 2. a building-integrated photovoltaic-thermal (BIPV/T) system; 3. a two-stage ground-source heat pump with ECM (electronically commutated motor) fan used to heat/cool air in the house or an air source heat pump using BIPV/T air as the source to heat a storage tank; 4.
