Whitbread Premier Inn, Tolworth

Greengage acted as sustainability consultants and BREEAM assessors, from pre-planning through to post construction, on the recently completed, new build Premier Inn, located at 12 Kingston Road, Tolworth.

Achieving BREEAM ‘Outstanding’ with a Post Construction score of 87.69%, Tolworth Premier Inn is now the second highest BREEAM certified hotel, following Greengage’s earlier success with St Martin’s Lane hub by Premier Inn Hotel.

The development comprised the demolition of the existing buildings and construction of a new 137-bedroom hotel up to 8 storeys, including ancillary café, a ‘Thyme’ bar and restaurant with 110 covers.

The Premier Inn hotel was designed with high architectural merit, using quality and responsibly sourced materials. The exterior envelope comprised a mixture of materials including a Yellow Rustica Brick façade with accompanying Natural Copper Cladding Infill Panels and Aluminium Powder Coated Grey Windows.

With high scores obtained across all credit categories including 5 innovation credits, the hotel particularly excelled in its energy performance, achieving 22 of the 24 available energy credits. Air Source Heat Pumps (ASHP) with heat recovery technology were installed to provide space heating and cooling to all bedroom and public areas. With hot water being a major energy consumer for hotels and to maximise energy efficiency and minimise energy usage, hot water is generated primarily by CHP with a back-up of high efficiency direct gas fired water heaters with seasonal efficiencies of over 95%. The hot water systems selected have low NOx emissions to reduce the impact on the local environment.

In order to minimise the impact of the redevelopment on the local water infrastructure, water saving techniques were incorporated to help reduce site consumption. The water consumption (litres/person/day) for the Hotel, when compared against a notional baseline performance level, is reduced by a minimum of 50%. A key element of this performance is the installation of a grey water recycling system to provide 100% of all the WC flushing demand within the development.

Other sustainability initiatives which contributed to the BREEAM score were the biodiverse roofs, a comprehensive Building Management System and the successful diversion of 99% of non-hazardous construction waste from landfill. The hotel also has Secure By Design Accreditation.
