The first carbon neutral industrial buildings in London have been completed at the SEGRO Navigation Park Phase 2 in Enfield. Achieving carbon neutrality is also a first time achievement for SEGRO marking a continuing successful relationship.
The development consists of 173,130ft2 of Grade A warehouse and office space across three units which have all attained A+ rated EPCs and a BREEAM Excellent rating. Due to its excellent sustainability, the project was shortlisted in the commercial PV project category of the 2016 Clean Energy Awards.
The carbon neutral status was achieved by exemplary as-built air tightness, façade solar and thermal performance significantly in excess of the Building Regulations requirements, highly energy efficient M&E systems, LED lighting and photovoltaic panel arrays on the roof of the warehouse areas. The PV installation has a peak output of 535 kWp across the three buildings and is expected to offset approximately 240 tonnes of carbon per year.
The development comprises shell industrial space with the offices fitted out to a Category A standard. At an early stage the project achieved a pre-let with Camden Town Brewery taking Unit 1 as their new brewing headquarters. The overall development reached a successful completion in December 2016.
The project had its challenges, being adjacent to the River Lee Navigation, and being flexible to incorporate tenant variations to Unit 1 to meet Camden Town’s specific brewing needs.
As is usual with SEGRO developments, the scheme incorporated extensive landscaping to soften the overall appearance.
The refurbishment provides office space, along with the ground floor being granted A1 retail use. High-level exposed services were designed to give an industrial warehouse feel. The offices are heated and cooled by independent variable refrigerant flow (VRF) air source heat pump systems and illuminated by suspended linear LED fittings.
The building at 55 Colmore Row has been refurbished to offer 150,000ft² of high quality office accommodation, for which Watkins Payne supplied building services engineering, vertical transportation engineering, BREEAM duties and energy consultancy to achieve an BREEAM ‘Excellent’ and EPC B rating.
Nash House is located on the corner of Maddox Street and St George Street in London and was constructed in 1980s. The site is right in front of the Garde I listed Church of St George and stone throw away from famous Handover Square. Currently ground floor is occupied by a retail tenant where the lower ground, 1st floor to 5th floor is office accommodation.
Apex Tower located next to New Malden train station is a 15-story office development. At ground level an enlarged prestigious reception area is provided which leads to commuter facility with unisex showers and drying room. The refurbishment works is targeting BREEAM RFO ‘Very Good’ and achieved an Energy Performance Certification rating of ‘B’.
Watkins Payne reviewed a number of mechanical and electrical options with the team, focusing on retention of key central plant, overhaul and replacement of plant where required, and LED lighting to reduce energy and improve the office environment.
The office building is targeting Energy Performance Certificate (EPC) rating of A.
