This paper describes an introduction to a simple modelling tool for designers of environmentally sensitive buildings.
The theoretical basis of the program is explained with examples given of typical program output.
The package can be used as an environmental simulator of a building's energy consumption and energy‐related carbon dioxide emissions. It is specifically designed to help meet the more stringent requirements of the Building Regulations for Fuel and Power L2 Approved Document, April 2002.
The designer can explore building size, shape, fenestration, orientation and fabric thermal properties to minimise a buildings' environmental effect. Aspects of heating, lighting, and natural and mechanical ventilation with heat recovery systems can also be investigated. The spreadsheet is best used to check that buildings will comply with the regulations or used as an early design aid rather than a detailed design simulator of building performance. The program should therefore be of particular interest to architects, building surveyors and building control officers rather than building service engineers.
Describes an innovative approach to thermal design.
