Understanding total emissions from cooling systems in urban buildings.

Résumé

Refrigeration, air conditioning and heat pump (RACHP) systems currently account for up to 19% of UK electricity use and over 7% of all UK greenhouse gas emissions. Under existing scenarios global warming and the trend towards urbanisation will result in increases in both cooling demand and the associated emissions. The UK commitment to reducing greenhouse gas (GHG) emissions by 80% by 2050 requires new and innovative approaches to the cooling of buildings: cooling loads must be reduced through optimisation of the building’s design and operation and new low carbon methods of delivering cooling developed. This paper is based on a research study to characterise the energy demand and carbon footprint of cooling in buildings. A new dynamic energy balance model and a software tool have been developed for estimating the energy flows and carbon emissions from all sources. These can be used to predict the impact of alternative building design concepts, different types of RACHP system and alternative strategies for managing the building.
