Phase 1 of this project involved the design and construction of a new manufacturing facility with R&D and offices for this Plymouth-based company. Situated within the International Business Park at Derriford, the project has been driven by an RDA requirement to achieve BREEAM ‘Excellent’. The accommodation comprises a manufacturing area of 31,807sqft, with support facilities of 18,040sqft wrapped around two sides. The site also accommodates a large service yard, staff and visitor parking and elements of external plant.
The plan depth of the office spaces was kept to less than 7m, providing efficient natural lighting and ventilation. The building incorporates various systems for managing and reducing energy use. A VRF system uses the heat recovered from cooling to preheat the hot water supply. This system individually and efficiently controls the heating, cooling and ventilation of the various office spaces whilst occupants can also open windows during the summer. The large production facility roof provides a 120kWp PV solar array with a predicted 9-10 year payback period. Rainwater is harvested from the roof for use in flushing toilets and urinals and storm water is attenuation on site below a permeably paved car park, all reducing the burden on the local drainage network.
To further reduce energy use, daylight and occupancy sensors efficiently control the lighting of the office spaces. Together with auto isolation and timer controls, the use of energy and water are both carefully controlled. The cladding materials were selected on the basis of longevity and ease of maintenance whilst also attaining the necessary BREEAM credits. Landscaping has been designed with habitat generation in mind as well as providing screening and site microclimate modification.
For phase 2, planning permission was granted in September 2017 for a further 1500m2 warehouse and 2500m2 of production and office space, in response to a growing market demand.
