Refurbishing the existing housing stock: priorities and unintended consequences
There are around 26 million dwellings in the UK and around two million non-domestic buildings, the majority of which will still exist in 2050. At present, these dwellings represent around 27% of the UK’s CO2 emissions and their poorly insulated fabric means they are both difficult and expensive to heat. It has been calculated that this may annually have led to between 25,000 and 30,000 cold related deaths in the UK. By simply refurbishing to much higher insulation and airtightness standards, this would reduce the operational energy required just to heat our buildings by more than 60%.
This seminar will be split into two parts. During the first part, delegates will be given an overview of the UK housing stock, and drivers for insulating it, including brief case studies of successful low-energy fabric efficiency upgrades. There will then be examples of unintended consequences of fabric upgrades, such as, ‘take back’; buildings becoming overheated; fabric damage; interstitial condensation with internal wall insulation; and, air quality issues (IAQ)). The seminar will also look at the principles of phased step by step upgrades, taking into account whole building performance, and it will suggest clients’ possible upgrade ‘triggers’ as opportunities, such as the replacing of a kitchen being the ideal time to look at internal wall insulation and water efficient appliances.
The second part consists of individual workshops with a given retrofit case study:
Delegates will critique and highlight possible unintended consequences of a case study’s retrofit
Delegates will propose alternative strategies for refurbishment
Extracts from the STBA’s Responsible Retrofit Guidance Wheel will be used to help assess and propose refurbishment strategies and retrofit checklists from the second edition of The environmental Design Pocketbook.
