Putting Ham Yard on the map

Ham Yard is just two streets north of London’s Piccadilly Circus. Named after The Ham, an inn from the early 1700’s, the cul-de-sac had a colourful history up until the Blitz, when it was flattened by bombs and left derelict.

Enter Tim and Kit Kemp, owners of the Firmdale Hotels Group, who saw the potential of this out-of-the-way site for their new flagship boutique hotel, Ham Yard Soho. With 8 hotels in the Group and £60m to spend, it was the perfect opportunity to further Kit’s enormous talent for interior design in a hospitality setting.

Great design in the guest areas and plant room

Launched in 2014, Ham Yard Soho offers 91 individually designed bedrooms, 24 apartments for hire and 13 retail outlets. There is also a gym, restaurant / bar, bowling alley and a theatre. Architects were Woods Bagot, London. The public spaces are endowed with artwork and objects from around the world, against a colourful background of unique fabrics and wall papers.

Plant room design was by Mecserve, Wallington. Heat generation is by 3 x LoadTracker XRGI 15G CHP units, backed up by 3 gas-fired boilers. Hot water at constant temperature is supplied to the DHW calorifiers, door curtains and air handling units. Hot water at variable temperature is supplied to the radiators, ceiling panels and towel rails.

Operation & Savings

The key difference made possible by LoadTracker units is their maximisation of running time. They can modulate down to 50% of full load in step with site electrical demand and can share load equally between all 3 units. The Ham Yard cluster thus has an operating range of 7.5 kW (1 unit at half load) to 45 kW (3 units at full load). As regards hot water matching, a 1,500 litre storage acts as buffer when demand is light and provides additional supply to deal with peaks.

Since entering service, all 3 LoadTracker CHP units have run regularly for up to 20 hours per day. By replacing expensive grid electricity with site-generated power, annual savings of around £28,000 are regularly secured.

Annual carbon dioxide reductions are around 79 tonnes.

An excellent example of multiple CHP installations in action.
