As the UK Building Regulations demand better insulatedand more airtight new buildings, a potential cooling requirement is emerging in new build dwellings in the UK, leading to an increase in the market for domestic air conditioning systems in this country.At the same time, current strategies at a European and National level are starting to focus on the use of renewableand low carbon energy sources, aiming at energy security and reduction of carbon emissions.Solar thermal cooling in small scale residential applicationsis of particular interest due to the major electrical energy supply proble

Throughout architectural history, local buildings have used great in providing the most comfortable internal conditions possible within the exigencies and constraintsof local climate.In Iraqis climates, accelerating airflow through induces evaporative cooling and across spaces, ensuring that directsunshine cannot penetrate the building and the thermalcapacity of massive structure is used to insulate and take up heat during the day and release it at night when it is cooler.

which is a typical residential building in the South MediterraneanSea. The house type is also representative for second home. It is a two-storey house that is assumed to be located in Rome.The objective of the research is to compare indoor comfortconditions of two kitchens (in which internal gains are defined taking into account a traditional use of the kitchen in Southern Italy) with different window configurations,natural ventilation and solar shading strategiesto avoid overheating in summer.Both rooms have the same floor area and the same total window area.

One of the main elements to consider in urban space design is the modification of the microclimate in order to improve the thermal comfort conditions of people livingin urban spaces.Sometimes it is very important to design very specific conditions for particular activities, time of days and season of the year. Design for thermal comfort requires therefore tools to provide an assessment of energy flows between townscape elements - persons and therefore an understanding of comfort conditions.

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.
