Funding for EcRoFit tool

A smart tool project for low-carbon building has received £1.5m European funding from the European Regional Development Fund (ERDF) and Birmingham City University (BCU).

EcRoFit, the result of two years of research into zero-carbon retrofitting by Dr Shadi Basurra and Professor Mohamed Gaber of Birmingham City University, will use the funding to provide a new tool for assessing energy efficiency and renewable energy use in domestic and non-domestic buildings.

Combining building simulation software, Artificial Intelligence (AI) models, a database of product and building specifications and a web portal, the iRet tool produced by the EcRoFit team will enable businesses to identify the most effective renewable energy solutions, retrofit solutions, balancing requirements for low carbon emissions, cost and occupant comfort.

Local suppliers of renewable energy and energy efficiency products will be able to use the portal to specify their products and add them to the iRet system.

Dr Shadi Basurra, of the EcRoFit project team, said, “Over the past few years, the UK government has identified six million houses built with inefficient solid walls that require improvement; Greater Birmingham and Solihull is recognised as one of the worst areas in the UK for energy efficiency in its housing stock. Policy initiatives such as the Green Deal Home Improvement Fund (GDHIF) have aimed to improve energy efficiency in homes.

“Typically, these schemes start with an assessment phase to determine whether – or not – the building will materialise its potential savings. Accordingly, if cost savings are achieved, the difference is paid back within a predefined time span, as an incentive. Given the large scale of any scheme related to increasing energy efficiency, in both existing and new buildings, and the capacity required to undertake energy efficiency assessments, it is inevitable to employ non-professionals to perform those assessments. It is feared that these basic and inaccurate calculations will influence the building energy performance and carbon emissions for many years to come.”

The EcRoFit project aims to support 80 energy assessors and retrofit supply chain with the iRet tool for better energy improvement decisions. With an average of 34.5 assessments made a year by an individual assessor, it is estimated that the total properties that can be retrofitted through 80 assessors is 256 properties per year. That is equivalent to a potential reduction of a total of 391.68 tonnes of CO2 per year.
