SAV plays key role in reducing carbon emissions from town regeneration scheme
Nearly 300 apartments in Phase 1 of the Barking town regeneration project are connected to a district-heating network by SAV heating and hot-water modules as one of the main measures to reduce carbon emissions by 32%. Another measure is the on-site generation of electricity using renewable energy.
The 10-year plan involves the district-heating mains being supplied by Barking Energy Action Network. Waste heat from the local power station and fuel derived from refuse processed at a local plant will also make contributions. Any further heat required by the individual networks will be generated locally using the most efficient low-carbon technology.
Special ultra-compact versions of the SAV modules were developed for this project, measuring only 680 mm high by 400 mm by 400 mm.
The units for this project generate hot water as required, so there are no storage losses, and hot water is instantly available without the need for a separate storage cylinder or clarifier.
Indirect versions of the module to be used in Barking have a second heat-exchange module that acts as an interface between the hot-water main supply from the boiler and the circuit in the dwelling. Heat can thus be taken efficiently from the central boiler, while maintaining a ‘sealed system’ condition for individual apartments.
When hot water is required at a tap or shower, energy is diverted from the heating circuits — an approach that is much more efficient at times of peak demand.
Also helping to maximise efficiency is constant modulating control.
Every unit for this project will have a built-in energy meter with a radio link so that it can be read remotely using a handheld Bluetooth receiver.
Building-services consultant is Atelier 10, and the SAV units will be installed by CPC Ardmore.
