36 APPROACHES TO HEATING & RENEWABLES FOR THE FUTURE HOMES STANDARD ROUND TABLE REVIEW RECOMMENDATIONS FOR INDUSTRY & GOVERNMENT
• Abigail Woolf, UKGBC: Include and regulate embodied carbon. The functional PV limits could be slightly less than the notional limits to allow innovation.
• Dr Jaydeep Bhadra, CIBSE: Revisit the metric used; energy use intensity is a better metric.
• Ronny Reeves, WMS: Keep the homeowner at the heart; and would love to see us designing to 40°C fl ow.
• Richard Lupo, Shift Environment: Post occupancy evaluation; housing associations have really good data.
• Mike Jones, Garo Electric: It would be great if we could futureproof power distribution more.
MULTI-DISCIPLINARY
The round table was held in the historic surroundings of Asia House in London, and featured fi ve sponsor representatives offering real-world insights
current policy pathway allow for innovation in hot water production and demand reduction?”
He said manufacturers were launching sophisticated ‘modulating’ electric showers, but Recoup’s new product had been languishing in the Appendix Q process with DESNZ for around 18 months, with “no defi nitive end date.” On the plus side, he confi rmed that WWHR was being adopted by housebuilders large and more SME-scaled, from Bellway Homes to Greencore (who were present at the debate).
Ventilation
Larry Soper of Envirovent asked the pertinent question, in the light of our warming environment and increasingly air tight dwellings: “How will the Future Homes Standard change how we ventilate dwellings?” He said robust ventilation strategy remained the “forgotten service,” as it was “easier to put a cheap fan in or trickle vents.” The new version of Part F launched alongside the Future Homes Standard was a mixed bag, he said: “It will push a lot more in the competence.” Richard Lupo said that claims against social housing providers were a risk as overheating became more prevalent, in the wake of the new Part O. “We’ve had clients with residents doing disrepair claims because their apartments are too hot and they can’t cool them down.”Mike Leonard from Birmingham City University shared the view that the Future Homes Standard was in fact the ‘Current Homes Standard,’ and that in 20 years, “overheating will be as big a problem as underheating is today,” while Prof Jankovich suggested this timescale was optimistic, and that Part O “needed evolution.” Leonard agreed ventilation was the “Cinderella of the industry,” and a “different approach was needed from developers, whether it’s market-led or regulation led.” He said: “We need to be thinking about centralised systems, whole house systems; we owe that to the public really, because air quality has a big impact on health and wellbeing, and we should be producing not just energy effi cient homes, but healthy homes.”
Larry Soper attempted to manage industry expectations on the potential of cooling using heat pumps combined with mechanical ventilation on some domestic sites, due to noise impacts.
• Prof Lubo Jankovic, University of Salford: Embodied carbon needs to be regulated, PV effi ciency instead of fl oor area, and constant set temperatures instead of intermittent temperatures. Also, consider positive health consequences of MVHR, and use hourly assessment of performance not monthly average.
• Jonathan Cheng, Dandara: Focus more on quality; of design, install, commissioning, and delivering a system that works with the occupier, and is not so complex.v
• Nathan Tranter, Panasonic Heating & Ventilation: We want one heating zone for properties over 150 m2 water value, more effi cient.
– more
• Dan Jestico, Savills: Retain the ability for local authorities to go beyond FHS in the new NPPF.
• Mike Leonard, Birmingham City University: Put the customer at the heart of this journey.
• Larry Soper, Envirovent: Ensure whatever’s specifi ed in the design is what’s in the completed house.
• Greg Jones, Hoare Lea: Be very cautious about predicting energy use, and have scenario testing so users understand likely product performance.
• Ellis Maginn, Recoup Energy Solutions: Integrate innovation better into modelling: the Appendix Q pathway doesn’t feel fi t for purpose currently.
• Ian Pritchett, Greencore Housing: This is not the last set of regulations that we’ll see; so try to encourage a holistic approach and legislate outcomes, rather than technologies. Also, correct issues and update as quickly as possible.
Conclusion: getting buyers on board Delegates homed in on the need to educate homebuyers on new technologies, and manage expectations. This would be crucial not only for building the reputation of tech such as heat pumps, but also helping counter a lack of trust in the industry among the public. Jonathan Cheng of Dandara said we had to design around consumers’ needs: “We can upskill people to use their homes in a different way, because the technology is different; it’s more complex, there’s more to understand.” However, he added: “Should we take a step back and try to understand users’ expectations?” With the Department having expressly stated its will to “re-engage with industry,” our round table showed why they need to pay attention to such groups. As we look forward to HEM’s eventual launch, the centre needs to hear candid cross-industry views on real-world impacts, if it hopes to get it ‘right fi rst time.’
