Impact of Thermal Model Resolution on Peak Heating Demand Calculation under Different Set Point Profiles (OR-16-022)

This paper presents an experimental and theoretical study of the dynamic response of low mass residential buildings and their respective space heating peak demands for different room temperature set point profiles, with a focus on the impact of thermal model resolution on the peak demand calculation. Experiments were conducted at two identically constructed and highly instrumented houses. The wood floor of one of them is covered with carpet. Their dynamic response to different ramping set point profiles is monitored and analyzed. Equivalent and physically meaningful RC network thermal models for the purpose of model based control are developed for a north zone of the houses.
