Building RegulationsImpact on the Heating
IndustryPresent and Future

• Dr Howard Porter
• Managing Director
• BEAMAEnergy
• Member of the Heating Strategy Group

2
BEAMAEnergy

• Trade association for the controls, metering,
  ventilation, electric heating and related
  industries.
• Managing several research projects for DTI,
  Carbon Trust and the European Commission
• Dr Porter sits on several heating industry groups
  including the HHIC, the partnership heating group
  and steering committee.

3
Heating Strategy Group

• Covers all types of domestic heating systems
• Membership of manufacturers, installers,
  merchants and energy suppliers
• Is the main body guiding the heating installers
  training
• Has in the past produced guidance such as CHeSS
• Advises the Partnership and the EST on heating
  related issues
• Chairman Peter Thom, of the IDHE, rep on the
  steering group Howard Porter, BEAMAEnergy

4
The Building Regulations

• A short history of its impact on heating
• 1996 Heating controls mandatory in new build
• 2003 Minimum efficiencies of gas boilers for new
  and existing build and minimum controls for
  existing build
• 2005 Minimum Condensing boilers for majority of
  installations
• 2006 Minimum performance criteria for all heating
  system types including controls for new and
  existing build
• 2010 ?????????????

5
Why has this happened?

• Increasing environmental pressures
• The 2006 Regs will reduce new build emissions by
  20-22 compared to 2002
• The 2010 Regs are expected to reduce this by a
  further 20
• Also the whole life carbon costs will be used
• Embedded carbon cost, carbon emitted during life
  and carbon used to recycle
• The heating industry is now making and will make
  significant contributions to the Governments
  environmental targets.

6
2005 -2006 changes

• Two changes in 9 months
• April 2005 the existing legislation amended to
  require condensing boilers in the majority of
  installations
• The boiler manufacturers, merchants and
  installers worked together to ensure a smooth
  transition thus far it is working!
• January 2006 the change of the whole of Part L to
  meet the EU Buildings Directive
• This will require minimum performance criteria
  for heating in new and existing buildings
• Minimum controls requirements for all heating
  types

7
Part L structure

• The structure of the ODPM documents will differ
  significantly to the present
• The ADL will be in 4 parts
• Domestic new build
• Domestic existing
• Non Domestic new build
• Non Domestic existing
• The structure of each document will also be quite
  different
• 1st Tier ADL
• 2nd Tier Joint Industry minimum guidance now
  to be an ODPM publication
• 3rd Tier Individual industry guidance, Good
  Practice Guides, Codes of Practice and standards

8
Structure of the heating industry minimum
compliance guide
9
Timescales and availability

• Expected to be published at the same time as the
  ADL
• Planned for Sept 2005
• Could be later
• Available as a whole document or by section
• On the ODPM website linked to many sites
• Published in sections
• Reproduced by industry licensed by ODPM

10
Beyond 2006

• The Consultation document for Part L gives some
  indications of the future
• A further 20 carbon reduction (42 reduction
  from 2002) for new build
• The inclusion in calculations of the embedded
  energy of manufacture and disposal/recycling
• The use of the Secure and sustainable buildings
  act to require more changes and upgrades for
  existing build
• In short compliance for traditional domestic
  building services products will be increasingly
  difficult even for condensing boilers!!

11
Existing Homes

• What can improve on condensing boilers??
• Solar thermal
• Underfloor heating
• Advanced controls
• Micro CHP
• Wood chip boilers
• Heat Pumps
• Integration of local renewables

12
New Build

• Very small space heating loads
• Most heating for hot water
• Small scale hot water focussed gas systems
• Innovative electric systems, heat pumps
• Ventilation/heat systems
• Fuel cells
• Micro CHP etc
• Solar thermal
• System and integrated approach required
• No one product alone will provide a complete
  solution

13
Examples for new build

• New 3 bed Semi built in 2011
• Space heating load of 1-2 kW
• Hot water load of 3-4 kW
• How best to provide this heat at minimum carbon
  cost, and build cost for developers and
  customers?
• Example gas based system
• Micro gas boiler, solar thermal, advanced
  controls, and mechanical heat recovery
  ventilation warm air space heating
• Example none gas system
• Very tight house, MVHR, limited direct
  electric/heat pump, solar thermal, very well
  controlled
• Controls and management of either system
  essential

14
Is there a role for buildings based renewables?

• Fuel cells could provide heat and electricity
• Micro CHP provides heat and electricity
• Photo Voltaic systems only electricity
• Small scale wind only electricity
• Will the Green electricity be sufficient to
  provide heat eg Mid day PV
• How will Long term green tariff contracts
  affect the assessment of possible solutions?

15
The effect of embedded energy

• The Regulations in 2010 are likely to include an
  assessment of the energy used for the manufacture
  and disposal/recycling of products backed up be
  the EUP Directive.
• With lower in use energy consumptions the
  embedded energy may become an important
  differentiator between systems
• Work underway in Europe to begin to assess the
  impact on some product groups

16
Regulatory tools need to be updated for a system
approach

• SAP/BREDEM, EE recommended and EEC methodologies
  need to be radically changed to assess accurately
  the carbon footprint of any system
• They need to be more flexible and allow
  combinations of products to be easily calculated
• How to get an accurate SAP assessment of an MVHR
  system, with a heating element, operating with a
  ground source heat pump supplying an underfloor
  heating system, with solar hot water and a small
  scale wind turbine and advanced controls
  managing all elements!!!

17
How to progress

• The heating industry is developing plans for 2010
• This will involve considerable co-operation
  between different products sectors AND Government
  departments and their agents
• Aiming to
• Deliver very low carbon emissions from domestic
  building services
• To be ahead of he game
• Maintaining customer satisfaction
• Proving a long term profit outlook for
  manufacturers

18
ESCO Directive

• The Energy End Use and ESCO directive has passed
  the first hurdle in the European Parliament
  very much to be welcomed
• Lots of media interest in particularly on the
  metering requirements
• Evidence shows that carbon reductions from
  display meters and innovative billing can be
  between 5-10
• Cost effective within 2 years
• Estimated savings per year in 2016 of 1.5Mtonnes
  CO2
• Much work required to implement the Directive
  into UK legislation
