When to employ occupant satisfaction evaluation

The BUS Methodology is a powerful tool in the development of quality, user centered building design.

Optimising building operation

By identifying features that both work well and may be improved, operational buildings can be optimised so that they are more satisfying in occupation.

Communicating success

By evaluating occupant satisfaction consistently before and after an intervention (eg. office move or lighting upgrade), successes can be measured and visualised.

Challenging better design

From a study of a single building, to explorative statistical analyses across 10,000's of records, lessons are learned that challenge better design.

Achieving building performance labelling and certification requirements

The BUS Methodology is a recognised tool for post-occupancy evaluation that contributes towards the requirements of BREEAM, LEED, WELL Standard, NABERS and Soft Landings.

What to expect from the process

BUS Methodology surveys are usually tailored to each project. However, a typical process may follow the steps below.

1
Preparation

Select a BUS Methodology Partner to guide you through the survey process and advise on the key decisions. The BUS methodology is licensed only to trained and experienced partners. Our partners will guide you in the best way to carry out the surveys and interpret the results. You can choose from paper or internet based surveys. Best results are obtained when all questions are asked, but certain questions can be omitted as it is recognised that some are not appropriate in all situations.

2
Data Collection

Distribute an appropriate version of the BUS Methodology questionnaire.The questionnaire typically takes 5-15 minutes to complete. It contains up to 45 quantitative and qualitative questions and seeks views on aspects such as: Thermal comfort and ventilation, lighting and noise, personal control, space, design and image. In commercial buildings occupants are asked about their perceived productivity and how they travel to the building. In domestic buildings, occupants are asked about their lifestyle and environmental issues.

Data Analysis

Questionnaire responses for the building are compared to a benchmark building set from the BUS Methodology database

Results

Results are presented in a number of ways: Summary results give a snapshot view of overall building performance. Results for each question are reported using statistical tables, graphs and plots. Slider graphics with traffic light markers are used for ease of interpretation. Anonymised narrative comments are reported. Your BUS methodology partner can interpret the results and put them into context for your building.

The benchmarking process

The results to each survey are compared to standardised benchmarks derived from the BUS Methodology building performance database to provide an indication of how the building performs relative to it's peers.

Benchmark samples are usually selected of common use type and/or geographical region.

Origins

The BUS methodology has been created from thirty years of continuous development in building use studies.

The method was developed and refined during the 1990's, when it was used for the seminal series of Government funded PROBE building performance evaluation studies regularly published in the industry press.

Since 1995 the BUS Methodology was curated and managed by Adrian Leaman.

Arup acquired the BUS Methodology in 2009 and worked with Adrian to establish the BUS Partner Network in 2013.
