Priva helps harvest renewable energy in farm development

The software engineering tool that is part of the Priva building-management system has been used to control a variety of alternative-energy sources for holiday accommodation in Cornwall and enabled the system to be set-up with minimal special work. Four barns at Mesmear Farm, St Minver, have been converted to offer holiday accommodation, teenagers’ activity area, swimming pool, housekeeper office/residence and workshop. The building services for the project were proposed by systems specialist Murch & Baker Heating. Danny Baker of the company explains, ‘The farm owner was looking for an energy-saving solution and using our knowledge of energy-management techniques, we were able to offer a design that incorporated both building controls and renewable energy.’ The result was the installation of a geothermal heat pump, solar panels and a borehole providing all the site’s water, controlled by a Priva Compri HX4 controller.’ The heat pump is used to produce water at 45 to 50°C for space heating and up to 55°C for hot water from a ground temperature of 8 to 13°C. The solar panels are mainly used for warming the swimming pool, with any excess heat being diverted to the heat pump. Electricity for lighting is drawn from the National Grid, but plans for self sufficiency in this area are being discussed with Murch & Baker. The architect for the project was so impressed with the design submitted by Murch & Baker that another residential project is being discussed.
