The RES Group of companies is one of the world's leading sustainable energy developers.
The RES Group's pioneering 'low-carbon' headquarters in Hertfordshire is designed to be entirely self-sufficient in heat and power from on-site renewable energy installations, including solar panels, energy crops and a wind turbine. We were employed to design, supply, install and commission the Trend BMS system which plays a key part in the control and monitoring of the renewable energy processes within the building.
Electrical energy is generated both by the wind turbine and by the photovoltaic modules within the solar panel array. This electricity can be used either within the buildings, or sold to the national grid when there is an excess. Heat energy is generated from the solar panels and the biomass boiler. The generation of solar heat is dependent on the weather. When solar heat is available and there is a heating demand, the energy is used directly to warm the incoming air into the buildings. In the summer, when no heating is needed, the excess heat produced is stored in the underground Heat Store for future use.
The generation of heat from biomass is dictated by demand from the building, with the biomass boiler firing as required. The conventional natural gas boilers are used only when the demand for heat is greater than can be met by the solar and biomass sources. Cooling energy is provided by using water at around 12ºC pumped up from the 75m deep borehole. This is demand-driven, with the borehole pump operation being controlled by the level of cooling needed in the buildings.
