NEF has been busy helping to solve a series of technical issues linked to delivering Energiesprong in the UK.
Energiesprong (meaning ‘energy leap’ in Dutch) is a form of retrofitting homes with dramatically better energy and carbon performance, tied to a performance guarantee so that tenants and owners can be confident about future running costs and carbon emissions. The retrofit work can usually be completed in one week, without residents having to move out.
NEF has been busy helping to solve a series of technical issues linked to delivering Energiesprong in the UK. We have developed a Domestic Hot Water Calculator to assess the demand for hot water in retrofit homes and to explore the most efficient ways to generate hot water in line with the Energiesprong performance guarantee.
We have developed a simple Occupant Satisfaction Questionnaire so that social housing providers can benchmark tenant satisfaction before and after energy retrofit work. We have also written a lay-person’s guide to the Energiesprong Performance Specification, so it is easy for non-specialist tenants and others to understand the outcomes of this form of retrofit.
NEF has also prepared four technical Briefing Papers, on:
1. Overheating risks and CIBSE’s Technical Memorandum 59
2. Electricity profiles for estates and groups of buildings (‘After Diversity Maximum Demand’, in the jargon)
3. Monitoring equipment needed to support Energiesprong work
4. Small Power Loads and the Energiesprong allowance for plug-in loads
