Why Zero Carbon Homes?

Costs of Achieving Zero Carbon
Some Design Implications for RPs
What is a zero carbon home?
A zero carbon home is a home that heats and lights itself through a
flexible combination of energy efficiency and renewable energy, and
may also make a contribution to cutting existing carbon emissions
elsewhere.
More technically, it is a home with zero net regulated carbon
emissions. ‘Regulated’ means regulated by the Building
Regulations, and covers space and water heating, fixed lighting and
ventilation, it does not include emissions from appliances or ‘white
goods’.
Why zero carbon homes?
Homes represent one quarter of the UK’s carbon dioxide emissions.
- The zero carbon homes policy mitigates emissions.
Consumer Perspective.
The Climate Change Act
Green Economy - it can also help leverage additional private
investment.
The Budget for 2013 reaffirmed the Government’s 2016 target.
Policy Detail
The zero carbon triangle - path to delivering zero carbon homes.
The zero carbon policy requires some of the carbon reductions to be
achieved on the site of the home, which is done in two stages:
– (i)Fabric Energy Efficiency standard (insulation etc), and
– (ii)Carbon Compliance (on-site renewable technologies and\or
additional fabric energy efficiency).
The remaining carbon can be abated off-site through ‘Allowable
Solutions’.
Approach to implementing zero
carbon homes
Staged Building Regs approach
Steps taken to date:
2010: Requirement for a 25% improvement on
Part L 2006.
2013: 6% uplift from the 2010 standard
2016: 100% improvement on Part L 2006 –
onsite level CSH 4.
Not cost effective to do all onsite.
The Consultation
Allowable Solutions Routes
1. Do more on site
2. Undertake own off-site
measures
3. Contract with a third
party ASP
4. Pay in to a national fund
Queens Speech and Outcome of
the Consultation Queen’s Speech - 4 June 2014 announced Infrastructure Bill.
Response to Consultation – Jul 2014 and seperately announced:
- On-site energy requirements at CSH Level 4
- Shortfall for zero carbon target met through carbon abatement
- Small Sites Exemption.
- No details on the level of a price caps.
- Government confirms that a national
design framework.
Pilot Projects
The HCA design and sustainability team is working with the Zero
Carbon Hub, local authorities and other partners to pilot options at 4
HCA sites:
- Hanham Hall,
- Peterborough,
- Graylingwell, and
- Whitehill Borden.

Small Sites Exemption Consultation
18 Nov 2014 to 7 Jan 2015
1. Site size, developer size or both?
2. If site size – what level?
3. If developer size – what criteria?
4. Exemption for energy efficiency?
5. Review period of exemption ie 5 years.

Exemptions for First Time Buyers.
ASV+C processes
The above will determine to overall size of the AS market.
