Portsmouth Naval Base Gas Works

A full review of all gas safety shut off systems within living accommodation and catering blocks to ensure compliancy and to reduce breakdown tasks where the gas system needs manually resetting, then replacing, as necessary. systems (Solenoid valves, extraction systems, gas detection units, forced ventilation interlocks, ect.) and a full review and replacement of obsolete/broken equipment, and replaced with up to date, compliant safety equipment. The short-to-medium term strategy for the NPC for Level 3 Sub-elements shall be based on a hierarchy of solutions that best reflects the future of the particular buildings concerned, for example. 1. Electric Heat Pumps (high temperature, CO2, heat pumps, cascade etc.) 2. Hybrid Heat Pumps (gas fired and air source) 3. Conventional gas fired boilers The solution for a particular building should be based on the following criteria. 1. Opportunity for a district heat network linked to other buildings 2. Pay-back period (given the potentially short asset lifecycle) 3. Thermal performance of the building and requirement for building fabric improvements e.g. double glazing and insulation 4. The requirement for pipework and emitter upgrades 5. Available footprint for internal/external plant 6. Spare capacity in electrical distribution boards, where applicable 7. Lead-time of equipment and installation/commissioning period 8. All works to be kept in alignment with Net Carbon Zero (NCZ) Strategy
