This project is part of the Retrofit for the Future Programme, funded by the Technology Strategy Board. The aim of the project is to demonstrate how to achieve 80% reductions in the CO2 emissions of the existing housing stock. The project was restricted to family houses, as they represent the bulk of the UK existing stock.
Our Client, Peabody, wanted to assess how to treat some of their more modern housing stock, built in the 1970’s and chose a terrace of four dwellings in Elizabeth Close in Haringey. The principle that was adopted in the design was to solve the emissions reduction problem by carrying out works outside the dwelling where possible. To this end, it was decided to insulate the dwellings from the outside, replace the windows with high performance versions and because the remaining heating load is low, to replace individual heating systems with a communal system. The communal system will be housed in a small boiler room at the end of the terrace, and will feature a large hot water store fed from a shared solar thermal system mounted on the roof. A small Photvoltaic array is also needed to achieve the 80% reductions.
The main internal works is to remove existing systems and make good, and also to install a Mechanically Ventilated Heat Recovery system (MVHR). This will contribute to reducing the heating demand in the winter months and will provide background ventilation to the kitchen and bathrooms all year around.
The project gained Planning Permission in June 2010 and goes on site in August 2010. The project will be monitored by the Energy Savings Trust for one year after completion.
HTA ustainability & Innovation carried out the coordination of the successful bid to the TSB and the SAP and other energy calculations necessary for the bid. We are continuing in this role including consultation and energy saving advice to residents, and will remain involved during the monitoring and feedback stages of the project.
