What We Do?
Perfect Green Group’s three operating divisions each bring a different blend of expertise, technologies, services and people to the table. Each one is designed to form a sustainable standalone business in its own right. They also work together, broadening the group’s total expertise and coverage of the green technology spectrum.
Who We Are
We have our roots in engineering: originally developing and installing heating, ventilation and air conditioning systems. As customer demand for green energy soared, Perfect Green extended its range of zero carbon heating and generation systems. We now provide a full suite of green energy technologies:
- Ground source heat pumps (GSHP)
- Air source heat pumps (ASHP)
- Solar thermal panels (SHW)
- Solar photovoltaic panels (PV)
- Combined heat and power
- LED Lighting
Our teams have worked on a wide range of public sector, commercial and residential projects; including schools and colleges, industrial and agricultural buildings. Read more
Our client had a requirement set by Bristol City Council to install a system which generated a minimum of 11,388kWh/yr. The neighbouring buildings are higher than our installation so we had to carefully 3D model the system to ensure it achieved the target, taking into account the shading affects. We also ensured the panels were strung so the lower row of panels were on a separate MPPT tracker to the upper row.”
Beacon House, University of Bristol
Our client had the requirements of BREEAM rating of Excellent and an EPC rating of A for this project. To help achieve this target we installed a 33.35kW solar PV system, split across the fourth and sixth floors of the building. The split level circular design of the building posed a number of challenges with regards panel layout and shading issues from the higher roof. We worked closely with the client to ensure the system worked both technically but also aesthetically, as parts of the system are overlooked by a roof terrace.
School of Governance, University of Oxford
Our client had a requirement from Plymouth City Council of a 15% carbon reduction from renewable energy. This system was designed to be capable of producing a heating only load of 130kW at a temperature of 45°C to circulate to the heating system. This was based on the specification requirement of each unit to be able to achieve 75% of the peak load if required.
