The approach of the building as a system in Time and its interrelationships with the environment, are presented as a “Matrix of Environmental Value (Ev)” that takes into account all possible aspects of “harmfulness – friendliness” towards the environment,

London’s urban heat island increases the mean air temperature which affects the demand for heating and cooling buildings. The simultaneous hourly air temperature in London has been measured continuously for a year. These data have shown that central areas

This paper presents an energy status study of a modern office building in the region of Xanthi. The results of the study are analyzed and evaluated with the use of appropriate software. Finally solutions are proposed for building’s energy rehabilitation.

This paper presents an analysis of some overlooked aspects in an environmental agenda for retail design. The work outline the analysis of the possibilities of maintaining low temperatures in an open-air markets stall space by using an appropriate shed and shading techniques and therefore avoiding direct solar radiation. Temperature difference of up to 100K was realised between shaded and un-shaded surfaces when some spot measurements were taken in the summer month of July (Ernest, 2004).

The performance of natural, mechanical and hybrid ventilation systems was monitored, using the tracer gas decay method, in three typical apartment buildings located in two street canyons, during summer period 2002 in Athens. The multi-zone methodology has been adopted based on the mass balance of two tracer gases (N2O and SF6) to define the air change rates. The air-exchange efficiency was determined for different ventilation systems, on the basis of the room mean age of air.

In order to perform detailed evaluation on the applicability of local dynamic similarity concept, which is described in Part 1, wind tunnel experiment was conducted under some conditions where the opening positions and the arrangement of buildings were changed in more complicated manner. As a result, it has been found that the discharge coefficient Cd can be predicted accurately from PR* for the most of opening positions, even if the approaching flow angle is varied or another building is standing near the opening.

This paper presents some results of the research project "Domestic Violence and Architectural Space", sponsored by several Mexican Governmental Offices and Citizen Organizations. One of the purposes of this project was to find the probable correlation between several physical characteristics of houses and violent behavior of their inhabitants. In this paper we report the results of the indoor climate exclusively.

Two approaches have been tested for cooling oil in a given location to temperatures well below the "normal" temperatures in that location. The first approach has been tested in Sde Boqer Campus, in the Israeli Negev desert. The soil was covered with a layer of pebbles, about 10. cm. thick, and watered in the mornings. The second approach was tested at A&M University in Tallahassee, Florida. Temperature measurements were taken of moist soil under a wooden shack on stilts, about 60 cm above the ground. Thus the soil under it was permanently shaded.

The architectural decisions for building that use natural ventilation should be taken in the initial stages of design when little information is available. A new approach is to compare the potential natural ventilation of known buildings in a new site and to adapt the design of the known example. The potential of natural ventilation may be changed by the barriers to its application: reduced wind velocity, higher temperatures, noise and pollution. Simple models, constructed on measurements, give an indication of the influence of these barriers.

This paper is a synopsis of the results of a research on form of wind towers. Wind tower is an architectural element in traditional architecture of Iran. It can be seen in cities with hot-dry and hot-humid climates. This analysis demonstrates wind towers' characteristics with emphasis on their morphology.
