Full Project Narrative
Low Temperature Hot Water Heating
The new pavilion is provided with a dedicated heating system serving underfloor heating installed to both levels.
LTHW is generated via a roof mounted Mitsubishi Electric Air Source Heat Pump (ASHP) with associated buffer vessel; pressurisation unit; expansion vessel & circulation pumps located within the first floor riser cupboard.
Heating water is conveyed around the building through copper pipework complete with crimped fittings. All pipework is insulated with insulation and sealed to ensure a vapour barrier.
Ventilation Systems
Ventilation is limited to localised wall mounted extract fans providing a minimum air change rate to the WC areas.
Air Conditioning Systems
DX air conditioning is provided to the new ground floor gym within the infill extension. An internal fan coil unit is wall mounted within the gym sized to cater for the sensible cooling load. The associated condensing unit is located at ground level on the gym’s external wall.
Cold Water Installation
The pavilion cold water domestic services are provided via a combined cold water storage tank & booster set.
The cold water storage tank provides approximately 100 litres of actual storage.
The cold water booster set provides 0.803 litres/second @ 5 Bar, and is mounted directly to the tank.
Cold water domestic services are conveyed around the building through copper pipework complete with crimped fittings. All pipework is insulated with insulation and sealed to ensure a vapour barrier.
