Options Appraisal for a Lido Restoration

Drawing of refurbished Lido

PROJECT DETAILS

Date: April 2023 – November 2023
Location: Cumbria, England
Client: Community Group
Stage: Low carbon heating options appraisal

TRE have undertaken a geological assessment and options appraisal of low-carbon heating technologies for a community lido restoration project.

The assessment first analysed closed and open-loop shallow geothermal options, and open-loop and co-axial deep geothermal options. Air-source heat pumps, solar PV and solar thermal technologies were also considered as complementary and alternative use options.

In order to evaluate the contribution that each low-carbon technology option could make towards meeting the overall heating demand of the site, TRE quantified the heat demand of the lido itself, as well as the space heating and domestic hot water requirements of the proposed building redevelopments.

Our findings identified that a hybrid system of closed-loop ground source heat pumps and air-source heat pumps would deliver optimal cost and carbon savings for the client.

The recommended next steps by TRE are to carry out a detailed design phase of the heat pump design and borehole array and perform a subsequent techno-economic analysis to support investment decisions and funding applications, in the context of a feasibility study.
