20 Chilled Beams
Beaming the light on sustainability
t is estimated that buildings account for 40% of the UK’s carbon emissions and their HVAC systems are major contributors.

Chilled beams can generate significant energy savings. As we look to achieve more with less and increase our buildings energy performance, chilled beams can play a major part in helping buildings become carbon neutral over the next 15 years
Commercial buildings are being increasingly encouraged to dramatically improve their overall performance and energy efficiency.
The European Commission in 2013 published a report on progress by member States towards Nearly Zero- Energy Buildings (NZEB). By the end of 2020 the goal is for Europe’s building’s to be NZEB rated and for all public buildings to be compliant two
years earlier in 2018. The technology is available, the industry is willing but can this be achievable in the timescale? Achieving energy savings in buildings is a complex business.
Buildings have many uses are susceptible to differing occupancy levels and subject to many changes. A building’s HVAC system is a fundamental component that can determine how effective the internal environment is and the impact on its occupants.
Chilled beam technology can offer enough flexibility to address a wide range of permutations for most indoor climates and can help building designers and owners meet legislative requirements without compromising on comfort, increased costs and performance. Chilled beams offer many advantages; their minimalist but functional design

allows for easy installation and the lack of motors, fans, filters, condensate pumps or other moving parts negates the need for costly maintenance.
Acoustically, beams are very quiet, reduce the need for ceiling voids and take little space.
In addition to reducing building costs, beams are also aesthetically attractive making them favoured in buildings which have pushed the design envelope. Functionally they provide a stable output and deliver a good cooling load while reducing the need for mechanical refrigeration.
Free cooling can also be achieved which further maximises a building’s energy efficiencies.
Flexible designs
Although energy savings are a key focus for many system designers, understanding
