Present: Clare Murray (LevittBernstein & LETI), Tim Starley-Grainger (LBH), Helen, Stuart, Cara, Quentin, Joyce, Chris, Tim Root, Alan, Dermot, Norman
- Haringey’s DEN plans (see more detail in presentation)
- Tim S-G has worked at Westminster and for BEIS on local energy networks
- Heat represents 44% UK energy use and 37% of CO2 emissions. 85% homes use gas.
- In some places eg Wales, green gas and heat pumps could provide low-carbon heat to most homes. But this doesn’t work in high-density places like London.
- Alternatives? Stripping H2 from natural gas and storing the CO2 residue (but no known safe storage system); H2 from electrolysis when surplus electricity in summer – but it is only 50% efficient and storage is big problem; CHP is 37% greener than normal gas – but experience shows it isn’t used when cheaper gas-fired heating available; heat pumps, but also more costly to run than gas; or heat networks, but it’s a challenge to get low-C sources. Solar thermal works but is expensive.
- Haringey heat networks being built into Tottenham Hale developments, N Tottenham, Broadwater Farm (850 homes) and Wood Green. Will use gas initially but aim to connect to EfW.
- NLWA Energy from Waste would be low-carbon (the heat would just go to waste otherwise) but need £6m to build pipe to connect Meridian Water/ N Mid Hospital to N Tottenham, BWFarm.
- Clare Murray works for LevittBernstein but takes part in LETI. London Energy Transformation Initiative is collaborative research project of >250 people aimed at bolstering London Plan and its implementation through eg SPDs. Feeding into UK Green Bldg Cl report due this month. Zero Carbon standard in new London Plan will apply to developments of >10 dwellings.
Zero Carbon building – can look at in hierarchy: regulated emissions (Part L) (heat, light etc); regulated emissions + mains electricity usage via plugs; and then adding embodied emissions.
Implementation has been a problem – 35% reduction on Part L is claimed but often fails, CHP is installed but never used etc. Plus there is lack of capacity in boroughs to enforce.
New builds are typically much better, 2/3 demand is hot water and only 1/3 heating. Main difference between this standard at Passivhaus is triple glazing and air-tightness.
Big issue is how we learn – press for disclosure post-completion of how buildings work in reality.
Key policies to push for? Implementation of SPDs to near-Passivhaus standard; getting carbon offsetting right, so it incentivises work on site without punishing developments that are doing all they reasonably can (and thus discouraging them and taking money away from other necessary things like affordable homes).
LETI welcomes people to get involved.
We agreed that we should formulate some clear issues which we should push on, including carbon offset pricing, good implementation. To follow this up by e-mail conversation.
- Update on Zero 50 plan.
This should be sent to officers etc in summer and ready for public distribution in autumn.
“In the next six months we will:
- Launch the Cycling and Walking Strategy
- Launch the Climate Action Haringey Plan
- Complete and act on the ULEV Action Plan
- Review the cost of local carbon offsetting
- Launch the Affordable Energy Strategy
- Deploy the second phase of charging stations for EV’s.”
- Next meetings.
Agreed we should look at food issues, esp opportunities to reduce meat and dairy. To discuss by email inc who we could invite.
