BUS (Building Use Studies) methodology
The BUS methodology is the original method of evaluating occupant satisfaction and has been developed over the last 30 years. It is an established, tried and tested way of benchmarking levels of occupant satisfaction within buildings against a large database of results for similar buildings. Results can be used to create solutions to improve the occupant experience and optimise building performance.
The method was developed and refined during the 1990s when it was used for the seminal series of government funded PROBE building performance evaluation studies regularly published in the industry press. It has been used on the Carbon Trust’s Low Carbon Accelerator and Low Carbon Building Programme and also on the Technology Strategy Board’s Building Performance Evaluation programme.
Over 45 key variables are evaluated covering aspects such as thermal comfort, ventilation, indoor air quality, lighting, personal control, noise, space, design, image and needs. Twelve summary variables provide a snapshot of the overall building performance.
