3D Modelling Case Study

Renewable Case Study

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.

Both models were run through a CO2 emissions calculation to produce a BRUKL report and Energy Performance Certificate (EPC)in accordance with the requirements of Approved Document L2B.

From this the required thermal conductivity performance of the new glazed facade was determined.

The two BRUKL reports / EPCs were then compared to show an overall decrease in CO2 emissions resulting from the new facade and a detailed report compiled for submission to Building Control.

With the new facade, the building’s EPC rating reduced from 91 to 88 (within band D).
The success of this project was due to the commitment from the team to survey the building in sufficient detail to produce the 3D models and the close relationship with the Architect in ensuring that the glazing specification proposed was sufficient to meet the requirements resulting from the calculations.

Renewable Energy - "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 boiler.  Woodchip 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.
