@g__j Let’s cut the red tape. Utilise to optimise …. in this instance. Whereas minimise to optimise in demand.

You can’t run an efficient renewables-heavy, distributed energy system without price signals to match supply & demand, drive investment to the right places Wind & solar are v cheap- but not if we have to pay them to switch off, or build an unnecessary & unfeasible amount of grid

@kenbone44 Thanks for sharing. I wonder if there’s much difference in carbon emissions in this strategy e.g grid carbon peak/ good COP vs grid carbon off peak/ less good COP.

@betateachpod @MarkSiddallRIBA @AR_Clarke @_heatgeek @JeremyClimas @glynhudson @Protons4B @Johnny__Hancock @NIBEEnergy Compact unit with direct electric rad top up?

@MarkSiddallRIBA @AR_Clarke @_heatgeek @JeremyClimas @glynhudson @Protons4B Hi Mark, have a chat with @Johnny__Hancock from @NIBEEnergy about exhaust air stuff. May not be right for this project but will give you ideas for the future. Johnny was on the podcast not long after you I believe

I’m working on a 3 bed retrofit property with a space heating peak load just under 2kW. Mindful of SCOP, which heat pumps are small enough for this? Any tips would be appreciated @AR_Clarke @_heatgeek @betateachpod @JeremyClimas @glynhudson (Aware of @Protons4B recent thread)

@SallyGodber Oops

@EsTresidder The cost of panels is very low currently that I think even at smart export guarantee tariffs (4.5p/kWh) they could pay for themselves in about 12-15years 🤞. Much of prelims (scaffold etc) already covered. I’ll let you know how I get on…..when I can afford it also😅

@RupertDaly Yeah agree wider decarb good motivator but at this stage I need to make sure it pays for itself in 💰 too, to justify taking the interest free loan for money we no longer have. 🤣

Looking at quotes for solar PV and battery. We've got a good SSE facing roof, no shading, but our electricity use is so low (4,000 kWh/y I'd estimate, but hard to know as only been back in the house 5 months) that I'm not sure it'll stack up financially.

@dan_grey @Damon_BPHR Good to know re: EV chargers. 👍

@RupertDaly @Damon_BPHR All EV chargers are load-balancing by law now, so this is never a problem

And so it starts… the path to electrification and decarbonising has just got a hell of alot harder.

@55n @WeAreSussed @HolmesMiller @MaxiConstruct ‘We’re going to need a smaller fan’… great to support this project through the site phase as part of @WeAreSussed. Awesome result is equivalent to a 10% reduction in residual space heating demand - equivalent to 100mm less insulation to all walls! I.e. Quality can reduce costs!

Airtightness testing recently at the Sciennes project we're working on under the @WeAreSussed banner. Designed by @HolmesMiller and built by @MaxiConstruct Excellent results!!!!

@EsTresidder @GreeningHampsh1 @betateach @fridge_girl @JurajMikurcik @WolfgangFeist Could you use a waterless dry trap same as MVHR?

@GreeningHampsh1 @betateach @fridge_girl @JurajMikurcik might know what to do here, or @WolfgangFeist. How did you guys make the condensate drain airtight on your air to air minisplit units? I totally hadn’t clocked this, thanks @GreeningHampsh1 !

SVP airtightness done. Fiddly cos so close to batten but managed to get some Vana wiggled in there first and pressed down with a blade before finishing off with spare Extoseal.

Where are global emissions heading and where should they be going to keep #globalwarming well below 2C and 1.5C? Today, @UNEP released the 2022 #emissionsgap report. A look at the key messages but caution, not much good news ahead 🧵/1

@TimMeek8 @JurajMikurcik Pretty sure this was painted black. Has the west coast exposure stripped it back?

@JurajMikurcik I wonder when we lost our confidence in colour? Could it be that natural has moral overtones? Perhaps what Bachelor calls ‘Chromaphobia’ is a consequence of ideas migrating north? Interesting.

@MarkSiddallRIBA @Michael_Dougall @55n @johngilbertarch @LovetoRide_ @Heritage_Meisie @ChrisMorganJGA @Drew_Carr_ About 3yrs but not frequent use tbh. It’s an earlier model so I think they fixed a few things on V3 with the additional gear and drum brakes. Good fun but best on fairly moderate inclines or flat and cruising. And works well with train commute. Doubled in price though!!!!

@RupertDaly @Michael_Dougall @55n @johngilbertarch @LovetoRide_ @Heritage_Meisie @ChrisMorganJGA @Drew_Carr_ @RupertDaly how long have you had the 1/2 bike, what what’s your review? Cooed with hills?

A Friday cycle ride and lunch in Shawlands with @johngilbertarch team as part of #lovetoride #CycleSeptember.

@PassivhausTrust @AnnMarieFallon_ @ArchitypeUK Couldn’t agree more! A big ticket item which needs considered early in design affecting material, labour, sequencing and programme…..potentially long term maintenance costs too🤔

Form factor really matters! Really useful to hear insights from the different phases of the Agar Grove #Passivhaus scheme during our 1st #PHTMasterclass on Large & Complex projects. @AnnMarieFallon_ @ArchitypeUK Sign up for the Masterclass series: bit.ly/PHTlargecomplex

@edeninsulation @AndrewMcQuarrie Good to see this trend emerging though I wonder if isoquick type floor is still a good way to go just with timber instead of concrete? timbatec.com/en/aktuelles/m….

@AndrewMcQuarrie The reduced amount of concrete makes it more eco friendly but in this form it does work more expensive an Isoquick slab for example. Worked well on site though as we had a nice level platform to build the walls on.

We were in Herefordshire last week erecting a #passivhaus timber frame where we also supplied the ground floor sitting on a pre installed pile a steel support. Having not supplied insulated ground floors before, this is the first of 4 jobs current job’s requiring them, new trend?

@thermalimageguy What a waste of time,money, material and energy!. The current ‘outcomes based funding model’ should hopefully mitigate this for future schools. I wonder if there could be a similar mechanism for retrofitting this one. 🤔

Gaffer tape holding the air tight layer together - that’s it. Now dried out and no longer effective, (if it ever was) - 2 years after this £9m school in central Scotland was built. Scotland’s shame, no adequate inspection. Nobody cares. I’ve messaged various green & snp….

@ElrondBurrell @SustainableTall Thanks @ElrondBurrell and @SustainableTall. I’ll be talking about this and comparing the great work by colleagues @johngilbertarch to deep retrofit #Passivhaus Glasgow tenements on Wednesday passivhaustrust.org.uk/event_detail.p…

Glasgow flats originally built in 1969 refurbished to reduce energy use by 80%. One resident said “I haven’t switched on my heating for two years as there is just no need” #RetroFirst glasgowlive.co.uk/news/glasgow-n…

@the_woodlouse This is a fantastic resource. Thanks for posting @the_woodlouse
