This lady has been lying with a badly injured shoulder on an isolated footpath for an hour in Fen Ditton. Can she be prioritised? @EastAngilaAmb The Good Samaritans with her have already rung 999.
Talking heat policy and hybrid heat pumps on a cold day with @Baxiboilers Jeff House, and @energygovuk Laura Brassell (hybrid heat pump policy lead at DEZNS)
Why certifying design rather than actual performance good for energy efficiency in buildings. As demonstrated by BBP’s Rob MacWhannell - the slide shows similar energy performance whatever the building's EPC rating #NABERSUK #Build2Perform
Since study there are more low GWP refrigerants available but system efficiency must be taken into account. Summary - minimise refrigerant volume, reduce leakage rates, gather data, specify low GWP.

Claire Brierley shares @hoarelea comparison study on whole life carbon of MEP systems in offices. Refrigerant has big impact on embodied carbon. Original study here

In the opening keynote at CIBSE #Build2Perform President-elect Vince Arnold says building services engineers have a unique opportunity to shape buildings and communities, and the urban enviroments in which they exist. @CIBSE
5 years after signing net zero into law @CSkidmoreUK says Conservative approach is hugely damaging because of move to new oil/gas licences and jettisoning of world leading position on net zero. ‘It makes me angry this has been thrown away as part of a culture war’ @InstallerSHOW

Heat network policy session first up at @FutureBuildNow John Allison (left) DESNZ: ‘Heat Network Zoning provides confidence that heat networks are the right solution for selected urban areas. It doesn’t mean heat networks won’t be most effective solution outside heat zones’
.@FutureBuildNow as busy as ever. Managed to get in a quick game of golf on @CIBSE stand before first session on heat networks. All balls with 19 seconds left if anyone is competing.

One explanation for England’s stubbornly high number of daily Covid-19 deaths @CebmOxford – at Cambridge, England
The rolling average of deaths in all settings reporting has been paused while PHE applies a correction to its death total.
This was in response to questions raised by this article

Snow cover is disappearing, sea ice is melting and fires, including possible ‘zombie’ blazes, are raging. @afreedma @MatthewCappucci
