There are a multitude of different tools and methodologies that can be used to assess a building's performance, some are well known such as SAP and BREEAM and others are lesser known being bespoke tools for an individual company. We have tried to collect a list of the tools and methods that are available in the UK and abroad but unfortunately may have missed some, if there are entries not mentioned then please let us know.
Please rate each tool/method below if you have used it. For discussion please use the section to the right. You must be logged in to the Connect platform to rate the tools.

CarbonBuzz is an RIBA CIBSE platform for benchmarking and tracking energy use in projects from design to operation. It is intended to encourage users to go beyond compliance of mandatory Building Regulations calculations and refine estimates to account for additional energy loads in-use. The platform allows users to compare design energy use with actual energy use side by side to help users close the design and operational energy performance gap in buildings.
A systematic way of undertaking an energy survey, reporting the results, and calculating likely savings from changes in use, technology or management. Useful at any stage in a building's life. The method is progressive and iterative, so you get useful results in relation to the effort you put in. A fullassessment (with all the associated fieldwork and enquiries) will typically take up to a person-week for a 10,000 square metre building. Detailed analysis and reporting can take longer, but only needs to be done if it proves important and cost-effective enough to do.
TM54 is evaluating operational energy performance of buildings at the design stage. The aim of the guidance is to enable designers to make better estimates of operational energy, identify the range of possible outcomes and therefore show how designs can be improved to deliver better on the predictions.
This is an evaluation tool that consists of an online questionnaire and structured workshops, which are designed to suit a wide range of people at almost any stage in the life cycle of a building.

OBU Pre-retrofit Survey
This retrofit project in Oxford targeted reductions in energy consumption of 85% by using an optimum mix of energy demand-reduction measures and well-proven zero-carbon technologies.
Office Productivity Network Survey
It is a questionnaire that asks building occupants to rate aspects of their work setting such as environmental conditions and office facilities. The main premise of the questionnaire is to determine how the variables listed might affect occupant productivity in the workplace. Has been condensed now due to the natural evolution of the technique. Each section contains a number of questions that asks respondents to rate variables against a scale. A detailed breakdown of time and task requirements is also asked for. The results are presented in a report with 'spider graphs'.

A relatively thorough examination of both hard and soft performances of a building by combining the techniques of walk-through survey; energy survey, occupant survey, discussions with occupants and management, and a pressure test. The published Probes were intended to look through the buildings surveyed and to disseminate findings to the industry, its clients, government and academe. The techniques are also applied in private consultancies to evaluate and improve both newly-completed and older buildings.
