Land Registry

Her Majesty’s Land Registry (Land Registry) was established in 1862. It is a nonministerial government department. It is responsible for keeping and maintaining the Land Register of England, registering ownership of land and facilitating property transactions. Land Registry installed M2G at their Peterborough site.

Sabien and M2G delivered

During the pilot, energy consumption and CO2 emissions were reduced by 15%. Payback was delivered in just 32 weeks. Annual CO2 savings of 7 tonnes have been delivered.  

Pilot Methodology

The test conditions and methodology were agreed with Land Registery. The pilot site was chosen by the client. The pilot was conducted over a period of 30 days. M2G can be configured to operate in either ‘Save’ (i.e. days when the M2G is operational and makes savings) and ‘Bypass’ (i.e. days when the M2G is bypassed and makes no savings) mode. A comparison of the boiler firing periods was made between Save and Bypass days. Variations in outside temperature were accommodated using industry standard degree day calculations.Ambient room and hot water temperatures were unaffected during the pilot period.

Sabien managed the pilot from start to finish, working closely with onsite engineers and third party stake holders.

What is M2G?

The M2G is an intelligent boiler load optimisation controller that improves the efficiency of each individual boiler. A unit, which can be retro-fitted to each boiler, monitors the temperature of the water in the flow and return every 10 seconds and the information is recorded with heat transfer rates at the first and second stage firings.

When a loading demand is made, the system automatically checks the latest data it has stored and decides whether it is more economical to retain first stage firing or to introduce a second stage firing. The result can be a substantial fuel reduction during less demanding situations while ensuring maximum capacity during heavy load periods.

Integrates with Building Management Systems

The M2G integrates seamlessly with the existing Building Management Systems. The majority of M2G installations are in buildings which have sophisticated Building Management Systems already in place.

15% savings delivered and payback in just 32 weeks

The M2G delivered energy consumption and CO2 emission reductions of 15%. Payback was just 32 weeks, annual CO2 savings of 7 tonnes have been achieved.
