Modelling Methodology

With our wide range of building performance simulation software, we perform computational modeling and simulation for optimizing the design and renovations of high-performance buildings. At SBD Lab, we perform building performance simulations using the EnergyPlus (DesignBuilder) program. Our simulations are validated through monitoring and field measurements of energy consumption and thermal comfort metrics.

The laboratory is equipped with various data acquisition /logging systems for different types of temperature, humidity, airflow, turbulence, illumination intensity and CO2 sensors, envelope air tightness (Blower Door), and infrared camera. Our methodology relies first on monitoring case studies and conducting audits to characterize the building construction, energy systems, and occupant behavior. Secondly, we create the simulation model and validate it based on the monitored data. We have a long experience with benchmarking different building typologies.
