Case Studies




RE:SURE are a business operating 24/7, energy use was high and they identified a need to manage that cost better. After a considering various options. They appointed us to supply, install and commission a 43kW Solar PV system at their Cookstown office.

Solar panels were installed on a south facing roof, perfect for collecting as much sunlight as possible throughout the day.

We used a SolarEdge Inverter and system monitoring platform. This allowed both b4b renewables and the client to manage and monitor performance.

During a recent system performance review, we were able to calculate that the system is operating within 4% of optimum levels. Meaning the Solar yield was only 4% less than estimated on day one

Communal Geothermal Heating System, Randalstown

Communal geothermal heating system consisting of 2 No. Ecoforest B1 5-22kw ground source heat pumps in the plantroom linked to 6 x 140m boreholes.

Domestic Hot Water heated as a by-product of heating production using the impressive Ecoforest HTR functionality, lowering running costs.

System installation in the plant room provides all the heating and hot water for each apartment.

Design and installation of Roth Underfloor heating and MHRV System by our team in each apartment.

Having the main plant located in a serviceable plant room means our engineers can do the bulk of the servicing without having to access people’s apartments. No more boilers in apartments, flues to the outside, gas top-ups and no more harmful emissions.

This project is part of a wider decarbonisation scheme by the Rural Housing Association. The ambition is that these energy efficient new-build social housing developments will support the sustainability of local communities


Queen’s University Belfast


The Queens University Belfast (QUB) playing fields caters for a number of different field sports and a multitude of teams within each sport, so as you can imagine there is a high demand for unlimited hot water.

We installed and commissioned 30m² of Solar Flat Plate Collectors to provide hot water for the new playing facilities.

This involved mounting 12 panels on a purpose-built frame on a flat roof overlooking playing pitches.

We also supplied and fitted Copper Mapress Pipe work from roof level to connect to a 1500L pre-heat vessel in the boiler house.

This meant that the incoming mains water is pre-heated by the solar panels, significantly reducing the load on its gas-fired water heaters.

The QUB sports facility has not only reaped the cost benefits in the reducing its utility bills, but it has also made a positive impact on its carbon emissions which is a key objective in the University’s Carbon Management Plan.
