New Art Gallery - Heat Decarbonisation

Descriptions

The Council is looking to appoint a single competent principal contractor to undertake decarbonisation works at the New Art Gallery Walsall. The project comprises of the following items to be partly funded by Salix via the PSDS 3c: o Strip out and removal of the existing gas boilers. o Replacement of the inverted roof system with new warm roof deck on the 4th floor to provide a 20-year insurance back warranty. o Installation of new handrail system to the roof and bigfoot system for ASHPs. o Installation of new ASHP and Water to Water Heat Pumps. o Associated fire-stopping works. The Council procured expert consultants to undertake carbon auditing across its estate including leisure facilities. For the New Art Gallery the following measures have been recommended, funding permitting: o Installation of an air source heat pump. o Installation of secondary glazing. o Installation of tap flow restrictors. o AtkinsR?alis have made a strategic assessment of the economic and sustainable approach which is the installation of a renewable heating system (air source heat pump). The proposal is to install: - Install a Mitsubishi NX-N Range air source heat pump with a 400v 3ph 50 Hz Phase Power plus DOL starter. - Install an accompanying Mitsubishi EW-HT range water-to-water heat pump with a 400v 3ph 50Hz Phase Power output. - A structural survey has been undertaken identifying the lower roof of the Gallery as being the only suitable location for the air source heat pump to be installed. The loading of the unit is to be spread using a Big Foot load spreading system. - The annual forecast energy savings following the works is estimated to be 270,684kWh. - Reduce the carbon emissions by 86.04tCO2 per year based on the Salix PSDS 3C application. - The investment will provide an immediate impact on the heating and energy demands of the Gallery.
