Sabien helps IMechE reduce its carbon emissions
The Institution of Mechanical Engineers has reduced gas consumption for heating and hot water in its headquarters building by 17% following the installation of Sabien Technology’s MG2 intelligent boiler load optimisers. The savings are over and above those provided by the BMS and amount to a reduction in carbon emissions of 25 t a year. Payback is put at 2.7 years.
Head of energy Brian Robinson explains, ‘The institution is very focused on the energy consumption of its buildings, and we have reduced our carbon emissions by over 25% in the last two years. We initially asked Sabien to pilot the MG2s and demonstrate the savings that would be achieved. Following the success of the trial, the units are now playing an important role in minimising our energy consumption.’
MG2 intelligent boiler load optimisation differentiates between a genuine need for heating and a call for the boiler to fire simply to compensate for its own standing heat losses. This ‘dry cycling’ can be a consequence of boilers being oversized and occurs more often during relatively mild weather when boilers are operating under light conditions.
