Abstract
The effect of energy efficiency measures is generally evaluated for one or only a few houses. While the energy and environmental optimization of a particular building design is crucial, this cannot easily draw generic conclusions for future building designs. A method is presented for considering the effect of building geometry in simplified energy and life cycle assessment studies. Based on architectural and functional considerations, realistic ranges were determined for the parameters describing the geometry of 'technically feasible' buildings and their relationships. These parameters include floor area, the number of storeys, the perimeter-to-floor area ratio, the ratio of the building envelope adjoining neighbouring heated buildings, the window ratio and frame factor, the density of partition walls, and the roof slope. An algorithm is developed for the random generation of a large building sample based on the realistic ranges of these geometric parameters. By analysing the results, it is possible to calculate the expected value, standard deviation and confidence interval of the sample. The application of the method is shown in an example. The cumulative non-renewable energy demand is calculated for the whole life cycle and for different building types.

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
