Abstract
The material and energy metabolism of the built environment stocks can be examined by use of a generic model framework that allows for a dynamic analysis where the stock's quantity, composition and quality are related to the demand for service provided to the population. The stock is classified by use of type-age matrices, according to what are the important functions, age structure and material composition of the stock. A mathematical model is demonstrated for calculating the relationship between annual stock size, annual stock change, past inflows and present outflows. This allows for quantification of the material and energy metabolism, in a system life cycle perspective, and its corresponding economic and environmental performance. Various aspects of the approach are applied to selected built environment stocks in Norway, and this paper documents part of this approach for building stocks and road bridge stocks.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
