Kalz, D E; Pfafferott, J; Herkel, S and Wagner, A (2009) Building signatures correlating thermal comfort and low-energy cooling: In-use performance. Building Research & Information, 37(4), pp. 413-432. ISSN 0961-3218
Abstract
A detailed analysis of thermal comfort in summer is presented for eleven low-energy, mixed-mode, non-residential buildings and one residential building in Germany, applying the comfort standards EN 15251:2007-08 and EN ISO 7730:2005. The thermal comfort ratings are related to the cooling energy use and the efficiency of generating the cooling energy. The buildings employ environmental heat sinks (for example, the ground, ground water, rainwater, and the ambient air) together with thermo-active building systems. This reduces the primary energy use of buildings without compromising thermal comfort. For comparison, an office building cooled in summer by night ventilation only is also studied. Comprehensive monitoring with fine time resolution occurred, accompanied by evaluation of the building performance based on measurements of the energy use for cooling and auxiliary equipment, the performance of the environmental heat sink, thermal comfort, and local meteorological conditions. The investigated buildings demonstrate that low-energy cooling with appropriately designed environmental heat sinks can be an energy-efficient concept for non-residential buildings without an adverse effect on occupant thermal comfort.

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
