The principal intention of the present study is the analysisof the both physical and social conditions of a rural community near to the City of Guadalajara in Mexico, with the purpose of establishing the environmental necessaryparameters to realize recommendations of energy savings in rural houses.By means of this project the feasibility appears of takingadvantage of the natural resources in a system of self-consumption and the rational exploitation of the natural resources.

Since 1999, several widely used building energy efficiencystandards, including ASHRAE 90.1, ASHRAE 90.2, the International Energy Conservation Code, and Californias Title 24 have adopted cool roof credits or requirements. We review the technical development of cool roof provisions in the ASHRAE 90.1, ASHRAE 90.2, and California Title 24 standards, and discuss the treatment of cool roofs in other standards and energy-efficiency programs.

Macroclimatic forces have been important factors ever since man first constructed shelter. Throughout architecturalhistory, local buildings have used great in providingthe most comfortable internal conditions possible within the exigencies and constraints of local climate.The habitual living way in Iraq is accurately reflected in the households organization, in their volumetric configuration,in the forms of useful locations they engender. Houses are compact with interior courtyard; the streets are sinuous and pass through houses volumes.

The consequences of the global climate change are perceptible even in Italy, where in the last 15 years the mean temperature values increased of 0.4 °C in the northern part of the country and of 0.7°C in the southern one. It is besides well known that the

In modern, extensively glazed office buildings, due to high solar and internal loads and increased comfort expectations,air conditioning systems are often used even in moderate and cold climates. Particularly in this case, passive cooling by night-time ventilation seems to offer considerable potential. However, because heat gains and night ventilation periods do not coincide in time, a sufficientamount of thermal mass is needed in the building to store the heat.

Heating and cooling buildings needs too much energy consumption; thing that is becoming rare and more expensive.Internal thermal comfort is essentially evaluatedaccording to bioclimatic conditions and energy consumption.So the aim of the study is to reach optimum thermal comfort conditions with less energy consumptionaccording orientation factor in semi arid climate.In order to point out the relationship between orientation and energy consumption a site investigation is undertakenin Constantine new urban extension called Ali Mendjelinew town.

The buildings’ environment plays a very important role in health matters and the quality of life. A series of experimental measurements were carried out in the residential sector of the greater region of Athens. Parameters influencing the indoor air quali

The paper describes a method to show how Building Simulation data can be interpreted to provide informationthat is of use to non-Building Simulation experts involved in the design of low energy Buildings.The method uses a heat balance simulation tool, Energy Plus, and focuses on analysing the inside surface heat balance breakdowns instead of only using the predicted overall cooling demand as would be usual.It relates the inside surface heat balance components to design parameters and the design scope for action, and presents results for the buildings response to the weatherseparately from t

The case study in question is that of the refurbishment of a building constituted by four school pavilions built in the post-war period of the 20th Century with very lightweight reinforced concrete arches and vaults. Different retrofithypotheses have been evaluated by the means of the ESP-r software tool, taking into account heating energyconsumption, summer free-floating temperatures, daylighting and space use.

After the terrible consequence of the Iraq –Iran war and recently USA attack over Iraq the urban green covering disappeared from large areas of the city, beside the extension of the building over the green areas. The negative effects of this phenomenon ov
