Indoor Environment and Energy Use in Historic Buildings - Comparing Survey Results with Measurements and Simulations

Increasing demand for energy efficiency places new requirements on energy use in historic buildings. Efficient energy use is essential if a historic building is to be used and preserved, especially buildings with conventional uses such as residential buildings and offices. This paper presents results which combine energy auditing with building energy simulation and an indoor environment survey among the occupants of the building.

Both when comparing simulations with measurements as well as with survey results good agreement was found. The two efficiency measures that are predicted to increase energy and thermal performance the most for this group of buildings were reduced infiltration and increasing heat-exchanger efficiency.
