Buzzing atmosphere this morning at @TheBristolCommons Festival of Commoning. The win-wins of rent controls, land disposal reform, pensions that support commons... Delighted to have been invited to be on the panel for the housing session. #CommunityOwnership #Recommoning
Previous project of mine back in my @berearchitects days is shortlisted for Residential Project of the Year at @CIBSEAwards tonight. Some impressive competition including the super geeks at @MaxFordhamLLP so fingers crossed! 🏆🤞 bere.co.uk/architecture/b… cibse.org/whats-on/cibse…
Very disappointed to see the Climate and Nature Bill not make it to vote today, and @UKLabour Gov for fighting it. Read the summary of the bill here (it's all sensible stuff): zerohour.uk/climate-and-na…
Incredibly disappointed that MPs didn’t get the chance to vote on the Climate and Nature Bill - a crucial piece of legislation to prevent climate breakdown & protect our natural world. But thanks to all those who backed it - I'll keep fighting for urgent climate action #CANBill
I & @MaximilianBloom have joined the (nerdy)-star-studded ranks of guests on the @ZeroAmbitions21 hosted by Dan Hyde & Jeff Colley talking about #VundaHaus & our innovative off-site manufactuered external wall insulation system for #retrofit! share.transistor.fm/s/85d4753a @KIN_co_uk
Great workshop yesterday with stakeholders from across #Westminster with @CityWestminster Retrofit Taskforce and @KIN_co_uk, and presenting on streamlining procurement in #retrofit to deliver better outcomes at lower cost
Awesome day with #Vundahaus (pitching our offsite EWI for retrofit) at #WeAreUndaunted The Greenhouse pitch day at the @Ri_Science. Alongside pitches from so many cool climate tech startups! Inc. net zero clay cement, recycled fabric fibre MDF, replica leather grown from DNA
Great to have such a full-house and insight-filled discussion at the panel discussion on tackling #retrofit at scale yesterday at #Futurebuild / #NationalRetrofitConference
TER and TPER should be kept separate and only used as ‘interesting to know’ numbers given they are constantly changing based on grid factors. Consider them dynamically updated metrics rather than anything to assess a building itself on. 9/9
If EUI is to be used for compliance, budget amounts can be used for currently 'unregulated' uses (aknowledging that occupant use can vary significantly). 8/9
The above 4 numbers give a simple but robust overview of the building’s performance as well as identifying how fabric, systems, and renewables are adding up to the overall performance (meaning poor fabric etc can’t be hidden). 7/9
3. EUI before renewables. This measures the energy the building uses at-the-meter. 4. EUI after renewables and energy storage. This measures the energy the building imports from or exports to the grid, measured at-the-meter. 6/9
2. Final energy use. This is how much energy the building needs inc heating/ cooling, hot water, ventilation/ ancillary/ fans, and other regulated/core building uses, & heat pump COP; exc 'unregulated' plug loads) 5/9
The best approach is using four metrics together: 1. Heating/ cooling demand. This is how much energy the building needs to condition it (inc the benefits of ventilation rate & heat recovery, but exc heat pump COP) 4/9
We need to move away from notional buildings for compliance and use better metrics (measuring as-built performance). Don't use TPER. We mustn't keep inc grid factors (which change constantly) in our compliance metrics). Generally FEE is useful, but not the whole picture. 3/9
There are some improvements proposed but mainly little tweaks. Big improvements are ruled out as not wanting to cause "disruption" to the industry. Year after year of consultations & minor changes is far more disruptive than 1 big progressive change. Or climate disaster. 2/9
When I thought @UKLabour couldn't get limper on environment theguardian.com/politics/2024/… On same day world 1.5C threshold crossed @GNDRising @sianberry Who's going to vote for a party who's 1 consistent feature is diligently avoiding standing for anything?
When the climate and young people are crying out for even more investment in a Green New Deal, delivering less than ever is not ‘pragmatic’ from Labour - it’s a collision course with reality and aiming your legacy at the bin before you even start.
I'm speaking at FutureBuild & the National Retrofit Conference on "Retrofit Design at Scale" with @Archima @loreanap & Nick Wilde. 13:30 - 14:15 on Wed 6 March on the Retrofit Stage at ExCel London. #Futurebuild2024 #NationalRetrofitConference24 #retrofit invt.io/1txbcsgsphg
@phplusmag @ecologicalbuild @G_B_Store @PorothermUK @KnaufUK @MarmoxUK @InternormUK @ThorsenJoinery @EcologyBS @BespokeBrickCo Really enjoyed working on this selfbuild project via @KIN_co_uk, helping Andrea and Sophia with the learning around passivhaus detailing and how to navigate the challenges and compromises driven my making the most spacially of the constrained site (and of selfbuild!).
Delighted to be moderating this amazing panel on delivering radical change in #construction to tackle #sustainability at #LondonBuild w/ the wonderful @Laura_Bar0n, Pablo Gugel, Rob McGill, Sam Bower & Craig Robertson. 16th Nov, 11-11:50, Olympia London: londonbuildexpo.com/speaker-invite
