International Energy Agency energy related environmental impact of buildings Annex 31.

Annex 31 is a multinational project to support researchers engaged in determining how to measure the effects of buildings on their immediate, regional and global environments. Fourteen member countries of the International Energy Agency's (lEA) Implementing Agreement on Energy Conservation in Buildings and Community Systems are involved in the work, divided into 8 tasks. Tasks involve the development of ways to compare a diverse set of procedures, from those that merely score buildings according to a prescribed set of rules to highly detailed methodologies that attempt to measure the environmental loadings of a building during its expected lifetime. Data on environmental loadings resulting from buildings will be surveyed and analysed. A report will eventually be produced on the work of the Annex as a whole with some intermediate supplementary publications.
