Choosing an environmental system can be a costly and risky exercise. It is not always possible to predict whether comfort targets will be achievable, or whether the running costs and maintenance will be higher than first envisaged.
Nine out of ten designs modelled recently in BRE's environmental chamber failed to achieve client requirements for occupancy satisfaction.

BRE provides an independent and impartial service that assesses the performance of heating, ventilating and cooling systems and advises on their suitability. We carry out physical modelling (using large full-scale or scale mock-up models), standard test procedures and stie investigations. Recent projects have looked at the performance of refrigeration systems with alternative refrigerants, displacement ventilation, chilled ceilings and controls for boilers, fan coil and vav terminals.

Indoor climate and equipment tests are carried out in BRE's environmental test chamber. This is a versatile facility that provides both qualitative and quantitative data on most aspects of indoor air movement, thermal energy balance and hvac performance.

Michael Swainson, senior designer at BRE's hvac engineering and test capability. He's waiting to answer your questions on the design, development and operation of physical test rigs of building hvac systems. He also has experience of monitoring whole building systems, specifically aimed at the production of high quality data for the validation of numerical models.
