The flexible, efficient office building

The project analysed two main office building types – high-rises and low-rises – and calculated a number of parameters, using the simulation program BSim. Calculations showed that the overall building design and orientation effect is moderate compared with, for instance, use of daylight control and low-energy lighting, computers, etc. Considerable energy savings can be achieved by use of natural ventilation in the summer, thus only using mechanical ventilation with heat recovery during the day in the winter. Open-plan offices result in a better indoor climate and lower energy consumption than cubicle offices
