Building Performance Simulation

Description

Building simulations tools are an integral part of design processes for modern buildings. They are used to estimate the performance of building envelope, heating cooling and ventilation systems, and other relevant components and services. Moreover, they are used to assess influence of human behavior and control systems. The present course focuses on applying dynamic building simulations and gives an overview of possibilities and limitations related to their use. In the course, a dynamic building simulation tool IDA Indoor Climate and Energy is used (IDA ICE). The enables simulation of thermal behavior of buildings as well as airflow modelling. Moreover, IDA ICE comprises a daylight simulation module. Using IDA ICE the course participants learn to set up a model for building envelope, including models for walls, windows, solar shading and natural ventilation. The components representing internal heat sources, occupant loads (emission of heat and moisture) as well as artificial lighting etc. are used to define human activities and associated thermal and moisture loads. The participants learn how to use models for heating elements (water radiators, fan-coils), cooling units (air conditioners) as well as air handing systems and energy sources (chillers, boilers, heat pumps, district heating substations). The course introduces use of different control components (thermostat, PI controller). Regarding analysis of results, the participants learn to use IDA ICE’s result visualization module comprising tabular results, graphical time series, heat map plots and 3D visualizations. Besides the actual model set-up and use, the participants are introduced to basic design principles for sustainable and high performance buildings dealing with the climate context, orientation, shape and materials for building envelope as well as choice of climate conditioning systems.
