Ontwikkeling energiekentallen utiliteitsgebouwen
report
In this research, commissioned by the Ministry of Infrastructure and the Environment, ECN determined the average gas and electricity consumption per square meter of floor space – or energy intensity – for 24 different building types within the commercial sector and a few industrial sectors. Several sources had gathered energy intensities for different building types in the past. Whether these figures were truly representative was unclear, because of the relatively small sample size in these sources compared to the entire building stock. In this novel study the problem of small sample sizes is overcome by combining a number of large primary data sources that were not previously connected and thus did not allow for energy intensities to be determined. We were able to determine not only energy intensities, but also the related bandwidth of intensities, due to the greatly increased population size in this study. Furthermore, the relationship between observed intensity figures with the year of construction and building size has been determined. ECN, in cooperation with EIB, has been working for several years to improve the data availability and data quality of the commercial sector as an input for energy-related studies. This present study significantly improves our understanding of energy use in the commercial sector compared to previous estimates; for example as reported by Sipma (2014).The data can be used for benchmarking, both by individual companies as well during energy scans. In addition, it can be used more generally for research that supports the development of energy policy in this sector. In the attachment [TNO-2019-P11713_UKsummary.pdf] the story behind the analyses is explained with four figures.
