Indicators Of Energy Efficiency
In Cold-Climate Buildings
Inernationales Forschungsprojekt Berkeley
Laboratories, 1998
Auftraggeber : International Energy Agency
Koordination : Laurence Berkeley National Laboratories
The purpose of this project was to develop and test new and existing
indicators of a building's energy efficiency. Such indicators have
many applications, such as in screening tools for energy audits,
establishing measures of performance in energy-savings contracts,
and tracking improvements in efficiency. These indicators should
make it easier to identify houses that are truly energy efficient
and to assist in comparisons with other buildings. We approached
the problem by studying individual homes rather than aggregate statistics.
Other IEA projects are examining indicators from an aggregate perspective.
This project did not achieve all of its goals but the analysis of
individual homes provides insights and recommendations for compilation
and analysis of aggregate or national data.
We explored energy indicators from the perspective of a building
scientist. How does the choice of indicators affect the apparent
efficiency of specific homes? And since indicators are used to compare
performance, does a home's ranking change with the indicator? Most
important, do the rankings make sense? Here again, we wanted to
use our building science background to ensure that the indicators
and rankings make physical sense. These questions are best answered
through examination of individual houses rather than with aggregations
(that is, collections of houses) because detailed characteristics
are generally not collected for large groups of houses. Nevertheless,
an indicator that fails to accurately rank efficiencies of individual
homes is unlikely to succeed when comparing the entire housing stocks
of countries.
