A design oriented indexing system for energy use and indoor climate

An assessment concept is being developed for iterative design of office buildings withintegrated energy and indoor comfort solutions. An indexing system has been devised thatincorporates environmental effects of energy use with thermal and atmospheric indoor climatein a score on a common scale from 0 to 100%, called the Eco-factor. Only the operativephase of the building life cycle is considered. Only indoor climate aspects that are closelyinter-related with energy use are considered: Thermal comfort and Indoor Air Quality. TheEco-factor is calculated by scoring functions based on physical properties. This paperdescribes how indoor climate is incorporated in the Eco-factor method.
