2014-02-07 16:18:26 - An example of British Land high-spec office development characterized by a strong focus on sustainability, above all in mechanical system design.
Designed by Bennetts Associates Architects and enjoying an outstanding Central London location, Marble Arch House is a mixed use development, comprising of 9.300 m² of offices, 4.500 m² of retail and ten residential apartments located in the adjacent 62-64 Seymour Street. The major component is office space, with large floor plates parallel to Edgware Road. Overall, the project adopts a confident modern aesthetic, in particular in the way it addresses views towards Hyde Park and solar control to the west-facing façade.
Extensive effort has been undertaken to minimize energy requirements and greenhouse gas emissions of the building through the adoption of the energy hierarchy aimed at: reducing the demand for energy, meet the remaining demands as efficiently as possible,
supplying energy from low-carbon or renewable sources.
Particular care has been taken for HVAC, that plays a key role in Marble Arch House, as in any other development.
The system is based on low emission gas boilers and two 2 Climaveneta high efficiency TECS chillers featuring magnetic levitation compressors, and serving a 4-pipe distribution system.
Air source units has been preferred by the plant designer Hoare Lea, following the concept of the whole building.Their reduced dimensions fit the limited space on the roof, optimizing green space and reducing aesthetic impact. Very low noise emissions of the units enhanced by an additional attenuation package, ensured the stringent acoustic emission targets of this project.
Air treatment is provided by high efficiency air handling units with thermal wheel heat recovery.
Given the necessity to ensure ideal space adaptability to the needs and specific requirements of future tenants, the designer has conceived a flexible system, especially as concerns internal distribution.
On each floor, HVAC options are integrated giving tenants freedom of choice between a traditional 4-pipe fan coil unit system, a passive chilled beam with displacement ventilation and trench heating system, a night time cooling option and an active chilled beam system. The Category A fit-out provides a 4-pipe fan coil solution to meet market demands.
