This paper deals with the use of passive solutions to reach thermal comfort conditions in aneducational building under specific tropical climatic conditions. A case study of a green highschool building located in the French tropical island of La Reunion at an altitude of 600mwas used.

A global methodology is developed to optimize concepts for extremely low energy dwellings, taking into account energy savings, environmental impact and financial costs over the life cycle of the buildings. Energy simulations are executed with TRNSYS. The ecological impact is evaluated through a life cycle inventory of the whole building, whereas costs are evaluated through a cost-benefit analysis. The multi-objective optimization problem is solved with a combination of genetic algorithms and the Pareto-concept. Firstly the optimization methodology is presented.

The paper discusses the newly revised ASHRAE GreenGuide, particularly as it relates to thetopic of indoor environmental quality. The updated Guide includes a new chapter on LEEDGuidance for Mechanical Engineers and a new chapter on building systems Impact on theLocal Environment- both indoor and outdoor.

The simulation of a building as a whole offers an image of its behaviour, reflecting thecomplex relation established between the outdoor environment factors, the buildingcharacteristics, the use by its occupants, and the parameters which intervene in satisfying thecomfort criteria. This paper gives an overview of the use of building simulation in Romania.It focuses on summer comfort.

A growing interest has been addressed to multi-energy systems in buildings that involve theintegration of different energy sources to cover the thermal and electrical loads of thebuilding. A modelling approach to multi-energy systems in buildings based on the concept ofhybrid energy hub is presented. The model has been customised to be used in the conceptphase of the building design, either as a system simulation tool or as a system designoptimization tool.

The use of bioclimatic solutions in architecture has been for a long time in Europe aconsolidated procedure, especially developed in northern countries. In the last years, in Italytoo, It has been followed through a good policy to increase the construction of buildingsequipped with solar energy harnessing system; many architectural competitions expressly askfor passive solar architectonic solutions.

In mid-2002 the Friedberg architects’ bureau Bremmer, Lorenz, Frielinghaus, which had been successful in the architecture competition, was commissioned to plan the new construction of the main branch of the Hagen Sparkasse (savings bank). The Sparkasse ha

Novi Sad is capital administrative center of the Province Vojvodina, one of two towns with active oil refinery crossroad of transit traffic artery and until recently great industrial town! In this paper are presented data of imission for basic pollutant matters in the air of the town, microclimate and health condition of children and adult population according to permanent reports of health services for preschool, schoolchildren and physician in primary health care (general population) for the period 2002-2005.

Near-extreme solar irradiance, ambient dry-bulb and wet-bulb temperatures are fundamentaldata for determining the peak building cooling load. Design solar irradiance has beenseparately and independently selected by both ASHRAE and CIBSE. This may result in overestimatedcooling loads, and in turn over-sized air-conditioning systems. Hence, a statisticmethod based on probability theory and heat transfer principles was developed for rationalselection of the three coincident design weather data used for calculating peak cooling loadsin a building with thermal lag less than one hour.

Sitsang belongs to cold Region in china and heating energy consumption in winter is very large. There is fairly scarce petrochemical energy, and that the oxygen content in plateau section is lower, which makes combustion become insufficient, so the cost of conventional energy is considerably high. However, compared with other regions in china, the best advantage of Sitsang is that it possesses abundant solar energy resources.
