DTU wanted to build a sustainable building for the Civil Engineering department, and it was requested to use the Integrated Design Method. The first part of the analysis involved the study of requirements set by the costumer, and an early simulation of two of the rooms of the building. Having selected the building for the study, the team went ahead and started formulating a proposal for the solution that was expected to have the best overall performance based on more detailed investigations using the program IESVE. The study was limited to the design of the building’s envelope and services for ventilation, heating, cooling, and lighting in the building. IESVE was used to evaluate the energy consumption and indoor environment based on the design. After the simulation with IESVE, the results for the energy consumption were of 20 kWh/m2 for the entire building.
