Aldwych Quarter benefits from Waterloo’s air distribution
Waterloo Air Products plc has supplied an extensive range of air distribution products for the multi-million refurbishment of Bush House – former home of the BBC’s World Service.
The 300,000 sq. ft. landmark office development comprises four buildings; Bush, Strand, Melbourne and King House. Collectively known as the Aldwych Quarter it occupies a strategic position on the north side of the Thames with excellent links to the City and West End.
The re-developed site provides high-specification offices and ancillary space constructed around a campus-style environment. Each building features contemporary finishes and services within the constraints of the site’s Grade II listed building status.
Much of the building’s interior was outdated and its obsolete services delivered poor energy performance. A new HVAC system was installed comprising a combined heating and cooling system to all zones provided by a ceiling mounted four-pipe variable air volume fan coil system. Air cooled packaged water chillers and CHW pumps are located at roof level within dedicated pump rooms.
The environment of each building had particular design parameters to consider. Internal design temperatures in the summer are 22°C ± 2°C and 21°C ± 2°C in the winter, based on external design conditions of 30°C dry bulb and 20°C wet bulb in the Summer and -4°C dry bulb in the Winter months. Ventilation rates in the offices were based on 6 l/s per m² based on occupancy of one person per 10m². Maximising performance and energy efficiencies were a major focus for Kato Kagaku Company Limited, the building’s the Japanese owners.
Waterloo supplied an extensive number of CS linear slot diffusers, DF louvred faced diffusers and plenums throughout each building. The small format continuous slot diffuser series set the industry standard in terms of aerodynamic and acoustic performance. The series offers excellent low flow rate air diffusion characteristics and high air handling capacity and is particularly suited to variable volume applications.
Flexibility characterises the ‘D’ multi-core diffusers, which are suitable for any commercial project which requires a high quality diffuser that can be integrated with various ceiling types. Five frame styles are available with 14 different air pattern control core designs for vertical and horizontal diffusion.
“The importance of air distribution and the dynamics of air movement should not be underestimated. A successful air distribution system combines thermal comfort performance with energy efficiency. Well planned distribution ensures there are no hot or cold spots, thus providing a comfortable user experience,” adds Rick Edmondson, Waterloo’s chairman.
Waterloo has been involved in a number of prestigious award winning projects and its involvement in the Aldwych Quarter demonstrates why the company is entrusted with projects that combine heritage buildings with the best air distribution systems available.
