Exmouth Market low energy / passivhaus

In progress
Exmouth Market, Passivhaus retrofit


The scheme at the end of Exmouth Market is a mixed use façade retention development, incorporating a new Passivhaus roof top extension. The scheme is intended to revitalise the north end of the historic Exmouth Market in Clerkenwell, London, and is due to start on site in January 2012.

The scheme extends the brickwork façade of the corner site, but replaces the dilapidated single-storey infill buildings with two new commercial units on the ground floor (108m2) and five residential apartments above (308m2).

Behind the existing facade, the lower apartment floors will have energy saving fabric improvements with internal insulation and upgraded windows. All apartments will be built towards the Passivhaus standard with the penthouse reaching the full certified Passivhaus standard. The specification of the penthouse will include wall-to-wall triple glazed Passivhaus-certified sliding windows with retractable summer shading, thermal-bridge free super-insulated building fabric, solar thermal hot water heating and heat recovery ventilation. All other apartments will incorporate similar strategies. These measures will maximise energy efficiency and ensure excellent indoor air quality even when the windows are closed in winter. Ecological planting covers the roofs and upper terraces, providing outdoor amenity space and reducing the visual impact of the new building on the historic streetscape.

The scheme for the Debenham Trust is part of the continued improvement of Exmouth Market and is seen as an opportunity to develop a low energy strategy for other refurbishment projects. It is planned that the project will go to tender early in 2011 and the Debenham Trust intends to retain these units for rental as part of their ongoing investment in Exmouth Market.
