Follow on Google News | RE:NEW Risk management tool for low-energy housing retrofitThe Greater London Authority (GLA) established the RE:NEW Support Team, funded by the European Investment Bank (EIB) and operated by Capita to help local authorities and housing associations in London assist their residents by retrofitting homes.
By: Six Cylinder Ltd The Greater London Authority (GLA) established the RE:NEW Support Team (https://www.london.gov.uk/ The assessment toolkit includes a triage risk matrix to plot retrofit measures against each other with respect to the degree of their technical risk. Each retrofit measure has its own inherent risk rating and a rating when combined with any other measure. A risk score from 0, indicates measures have little or no impact on one another, whereas 3, indicates measures have inherent vulnerability and require careful design and execution. The matrix also shows which measures should be considered together, and which should never be used in combination. At the design level, the matrix enables you to assess which measures work well together and which combinations will have inherently higher risks and may require specialist support to ensure that this risk is mitigated. An example might be a housing association planning to upgrade a housing estate to make it more energy efficient. The designer has advised a set of measures including external wall insulation, loft insulation and draught proofing and the installation of mechanical ventilation with heat recovery (MVHR). Each of these initiatives has inherent risks in isolation. However, in combination, the risks can be amplified. The insulation improvements will mean there is a higher risk of under-ventilation, which could lead to condensation problems and air quality issues. As such, it is vital to ensure that the new mechanical ventilation system provides adequate ventilation to the entire home. The matrix and risk assessment process allows the design to continue safely and efficiently from the earliest possible stage. The assessment toolkit also includes Retrofit Watch Points, a list of high-level considerations for the Assessment, Design and Installation and Handover Stages of the project, as well as plain-English tips for key things that need to be considered with each retrofit measure.
