Summary

Model-based predictive control (MPC) offers significant opportunities for building operation. However, it must overcome several obstacles to facilitate its widespread adoption. One of these obstacles is the lack of user-friendly weather forecast tools tailored for the implementation of MPC in building operation. This paper discusses the development of a weather forecast tool targeting this issue and a preliminary assessment of its accuracy. This tool uses raw forecast data from the Canadian national meteorological service as an input to create tables of data with a prediction horizon of 48 hours. High spatial resolution data makes it possible to obtain forecasts for a very specific geographic location. A post-processing treatment is used to obtain estimates of solar radiation on different planes of interest, such as façades, roofs or building-integrated photovoltaic installations. The forecast data can be obtained automatically at 6-hour intervals. An overview of the tool and its features is presented. An estimation of the accuracy of the weather forecasts is carried out by comparing predicted weather data with actual measurements in Canadian sites. Finally, possible future upgrades for the tool are discussed.
