40TW-h of energy was generated by wind power in the UK in 2015 A smarter laboratory Planning ahead to optimise energy use and improve occupant health and wellbeing A David Hamlyn Project Manager & Senior Engineer, RWDI David is an internationally- recognised specialist on the effects of climate on building performance, including wind and dispersion problems s we strive to create the next generation of sustainable, high-performance laboratory buildings, the health, wellbeing and comfort of occupants and neighbours is critical. Exhaust discharge and dispersion can cause discomfort and safety issues, as well as being expensive and energy- consuming to manage if not properly planned for. Designers must ensure hazardous or odorous exhausts do not re-enter the building air supply or negatively affect the building’s surroundings. For the long-term sustainability of these facilities, they also must implement R e a d o n l i n e at: u k s pa . o r g . u k / b r e a k t h r o u g h energy-saving techniques. The modern, smart laboratory should balance both aspects of design. How do you ensure both energy efficiency and safety? The first step is evaluating the laboratory’s surroundings. Although generic guidelines for stack design exist, these don’t guarantee safe levels at the building air intakes, and therefore understanding the potential aerodynamic influence of surrounding buildings and presence of existing intake and exhaust sources is critical to optimising new laboratory design.
