Energy sustainable development through energy efficient heating devices and buildings
Energy devices and buildings are sustainable if, when they operate, they use sustainable (renewable and refuse) energy and generate nega-energy. This paper covers three research examples of this type of sustainability: (1) use of air-to-earth heat exchangers, (2) computer control of heating and cooling of the building (via heat pumps and heat-recovery devices), and (3) design control of energy consumption in a house.
Application of COMIS software for ventilation study in a typical building in Serbia
Abstract Good exchange of air between rooms inside a building and outside is extremely important to achieve air quality inside the building. For a typical building in Serbia, this phenomenon is investigated by the software package COMIS (Conjunction of Multizone Infiltration Specialists). It is found that natural ventilation by infiltration cannot achieve good air quality inside the investigated building during summer.
COMIS v3.1 simulation environment for multizone air flow and pollutant transport modelling
Abstract COMIS simulates multizone air flow and pollutant transport. It has been developed in an international context at Lawrence Berkeley National Laboratory (LBNL) and within International Energy Agency (IEA) Annex 23. At the end of Annex 23, the Swiss Federal Laboratories for Materials Testing and Research (EMPA) took over the co-ordination of further developments, and—together with Centre Scientifique et Technique du Bâtiment (CSTB)—the maintenance of COMIS. In January 2001, the “COMIS v3.1 with IISiBat v2.4” package was released, and is available now from CSTB. In this paper, the main features of the COMIS simulation engine, and the latest improvements are presented. An example demonstrates the use of COMIS. Pollutant transport and impact evaluation with the new version are discussed. The coupling of COMIS with the thermal simulation program TRNSYS is discussed.
