Shieldfield Towers
Newcastle
PAS 2035 SHDF retrofit of three high-rise residential towers in Shieldfield, Newcastle.
Location: Newcastle upon Tyne
Client: Equans
Specialisation: Residential Tower Retrofit
ECD Architects, appointed by Equans, is leading this retrofit project of three high-rise residential towers: Lort House, Pandon Court, and King Charles Tower. The retrofit aims to enhance the thermal performance and aesthetics of these towers, bringing sustainable upgrades and improvements to over 200 residential units. The primary goal of the project is to increase the energy efficiency of the towers, while also providing an aesthetic uplift. Key upgrades include new External Wall Insulation (EWI), enhanced roof insulation, new energy-efficient windows, updated ventilation systems, and rooftop Air Source Heat Pumps (ASHPs).
This comprehensive retrofit approach addresses both the exterior envelope and internal systems to significantly reduce energy consumption and improve resident comfort. The existing façades are being upgraded with EWI to improve thermal performance and reduce heat loss. In addition, the spandrel zones beneath the windows will be retrofitted with a new steel frame system (SFS) infill, improving both thermal and fire performance. The roofs will receive a Bauder roof insulation system, further enhancing the towers’ thermal envelope. The existing rooftop plant room enclosures will be overclad with a Snaploc standing seam system to provide additional weatherproofing. New double-glazed windows are being installed to improve insulation and daylighting. The ASHPs on the rooftops will provide a renewable energy source for heating, utilising external air to generate heat, reducing carbon emissions associated with traditional heating methods.
To modernise the towers’ appearance, the design strategy for the EWI includes a simplified color palette that maintains the identity of each block while introducing a distinct character through complementary accent tones. The aesthetic strategy, focused on a cohesive visual language, has been developed in consultation with local planners.
