Renewable Energy Case Study

Renewable Case Study

Merlewood, Cumbria

“Merlewood” close to Grange-Over-Sands in Cumbria is a Lakeland home of the Holiday Property Bond. The first phase which became operational in May 2011, involved the conversion of the house into 9 apartments and a leisure centre.  The second phase comprises of 46 new build apartments which are due for completion in the summer of 2012.

The site is served by a 500 KW biomass boilerWoodchip is sourced locally and delivered from a local depot.   The boiler is fed via a leaf spring /auger system from the adjacent chip store.   The chip store is positioned within the landscape to allow delivery vehicles to tip directly into the store via a simple key switch powered lid.

After some initial commissioning issues the boiler has been operating at part load without issue. Heat from the boiler is delivered to a large thermal store.  Heat is then distributed around the site via pre-insulated below ground pipework into a series of plate heat exchangers and multi-energy tanks which generate domestic hot water and low pressure hot water. Oil fired boilers provide back-up and peak lopping. 

The Client needed a financially viable “green” solution to the non-availability of natural gas to the site. The relative cost of woodchip compared with oil indicates a “payback” during years  6 to 7 without RHI (renewable heat incentive).  The build is compliant under Part L.

3D Modelling - Canizarro Hotel, Wimbledon

This 300 year old 4 star boutique hotel in Wimbledon has 46 individually designed bedrooms. In order to create more internal dining space and to maximise the view out onto the garden area, it was proposed to enclose an existing ornate portico adjacent to the dining room, with a glazed façade and to provide heating to the space.

Building Control requirements were that the CO2 emissions from the building as a whole would not be increased by the new high performance glazed facade. In order to demonstrate this, the whole building was surveyed, the plant and system information gathered and a 3D building model was created for both the existing arrangement and the proposed enclosed portico arrangement.
