Abstract: The Drake Landing Solar Community (DLSC) is a master planned neighborhood in the Town of Okotoks, Alberta, Canada that has successfully integrated energy efficient technologies with a renewable energy source. The 52-house subdivision has space and water heating supplied by an innovative system which includes solar energy captured by an 800-panel garage mounted array, a borehole thermal energy storage system (BTES) for seasonal energy storage, and short-term thermal storage (STTS) tanks acting as a central hub for heat movement between collectors, district loop, and BTES. The system was designed to achieve a 90% annual solar fraction after 5 years of operation. A computer simulation was completed during the design phase to determine the appropriate sizes of the different components and the expected solar fraction for the project. Since completion of the construction of the subdivision, monitoring data has been collected for the entire system and this data is being used to calibrate the model constructed during the design period. This paper will discuss the original modeling of the solar district system and the calibration of the model with the measured data.
