The paper reports on a series of short projects undertaken in the course of the 2006-07 academic year as part of the AA School’s Masters Programme in Sustainable Environmental Design. The objective was to explore the architectural potential of adaptive co
The goal of this study was to suggest a low-density typologyfor commercial buildings to be applied in the cultural and climatic context of Athens, Greece, with minimal demand for conventional cooling. More specificallya typology of double enclosure was studied with self-contained structures sheltered within an outer shell. The research develops through studies of built examplesin Athens and analysis of the parameters affectingthermal comfort and adaptability. Dynamic thermal simulations were used to gain understanding of the energybehaviour of the double enclosure typology.
The paper provides a technical discussion on the developmentof zero energy building design strategies in the UK. Two building simulation software (TAS and TRNSYS) are employed to investigate various facade parameter studies as well as a solar service system. TAS building simulation is used to assess the effectiveness of passive strategies by taking building materials, window sizes and shading devices into consideration. TRNSYS is used for the investigation of the feasibility of using solar domestic hot water system in UK.
Commercial buildings with large exposed glazed façades require solar shading devices in order to protect occupants from uncomfortable direct glare. Automated window blinds can be used to reduce direct glare, while regulating the transmittance of daylight
Bioclimatic approach gives attention to the design of roof since it is commonly the building element which is most exposed. Some of the most favorable roof coolingtechniques are roof ponds which appear to influence the thermal behavior of roof through different processes including evaporation, radiation and conduction.
Sustainable development means that any encroachment into the ecosystem must be done in such a manner that the survival of future generations is not threatened in any way.In simple terms this means that we should leave the world for our children a better place that we found it.The notion of Sustainability in building and urban developmentrefers to the effects of building on the environmentin all their phases from the production of building materials to the use of ecologically sound and non-toxic substances in building and finally to the eventualdemolition of the buildings.It includes factors
Different types of thermal activation of building structuresare increasingly utilized in buildings including BIPV, multifunctional PV facades with controllable daylight/solar gain features and integrating thermal and electrical output.
This presentation projects the potential of mass interwovenwith other aspects of Bioclimatic Design, with the objective of energy conservation and utilization of renewable energy resources for indoor comfort.The variable of mass and its effect on other variables and parameters in building simulations are outlined and discussed.
As the EPBD related regulations can not cover all possible kind of new technologies, Member States have to develop “principle of equivalence” procedures, in order to allow the assessment of the systems not covered by the standard calculation procedures. This paper will first discuss the overall context, followed by a description of the approach used in several countries. Then, a brief summary of related international projects is given. Finally, there is a more in depth presentation of the approach proposed in Belgium.
A methodology approach in order to simulate numerically(CFD) a greenhouse equipped with fan and pad evaporative cooling system is presented. Using the main aspects of evaporative cooling systems in terms of heat and mass transfer, the flow and boundary conditions of the simulation model are identified integrating both the external and internal climatic conditions. The crop (tomato)was simulated using the equivalent porous mediumapproach by the addition of a momentum source term.
