Low carbon buildings programme phase II and its
implications for the second phase of the energy
efficiency commitment/carbon emissions reduction
target

• Mike Newell
• Low Carbon Product Manager

5
Low Carbon Building Programme

• LCBP provides grants for micro generation
  technologies for Householders, community groups,
  schools, the public sector and businesses
• The programme is UK wide and will demonstrate how
  Energy efficiency and micro generation will work
  hand in hand to create low carbon buildings
• Stream 1 grants apply to smaller projects for
  home owners
• Stream 2 grants apply for medium to large scale
  projects and are available to public, not for
  profit organisations

6
LCBP Key Objectives LCBP - Technologies

• Achieve reductions in the cost of micro
  generation technologies
• See micro generation technologies demonstrated on
  a wider scale
• Achieve greater visibility of these technologies,
  leading to an improved understanding by the
  general public as a result of their installation
  in a wide range of buildings

• Solar Photo voltaic
• Solar thermal
• Wind turbines
• Pellet stoves
• Wood fuelled boilers
• Ground source heat pumps

7
LCBP 2 Grant levels and current take-up at the
end of Yr1

• 50 grants available across all the technologies
  for new applications
• 8.6million committed with 40million still
  available

8
92 percent of funding still available for GSHP

LCBP Nominated Suppliers CERT Obligated Energy
Suppliers

• LCBP
• Framework supplier tenders to establish the
  routes to market
• Applicants bid for any or all of the technologies

• CERT
• Energy Suppliers have an obligation to deliver
  the carbon savings under CERT as part of their
  licence to supply energy

11
Proposed key changes for CERT - Ofgem

• Ofgem have also made a number of key changes to
  the administration of CERT
• Changes to the delivery mechanisms
• Changes to the number of measures suppliers can
  distribute
• Changes to the measures suppliers can claim as
  qualifying action

12
Proposed key changes for CERT - Ofgem

• Qualifying action is an action that promotes a
  reduction in the carbon emissions for the purpose
  of
• Achieving improvements in Energy Efficiency
• Increasing the amount of electricity generated or
  heat produced by micro generation
• Reducing energy consumption

13
Proposed key changes for CERT - Ofgem

• Innovative Qualifying action in CERT
• Market transformation qualifying action - is an
  action which was not approved as a qualifying
  action under The gas and electricity (Energy
  Efficiency Obligations) Order 2001 and which is
  expected to achieve a significantly greater
  reduction in carbon emissions than other
  qualifying action of that type.
• Demonstration qualifying action is an action
  which might reasonably be expected to promote a
  reduction in carbon emissions where it has not
  been possible to determine a specific carbon
  saving

14
Proposed key changes for CERT - Ofgem

• Additionality suppliers must demonstrate
  additionality as follows
• Social Housing Suppliers should seek a
  declaration form signed by the partner
  organisation
• Retail Schemes Suppliers should provide EPoS
  data from their retail partner.
• Alternately if EPoS data does not exist a
  marketing plan should be submitted to Ofgem
• Microgeneration suppliers need to prove that
  measures installed in new build properties are
  additional to those required under law (e.g.
  Merton Rule)

15
Proposed key changes for CERT - Ofgem

• Microgeneration
• LCBP Ofgem are proposing that suppliers use the
  current LCBP framework for the first year of
  CERT. The UK Microgeneration certification
  scheme (UKMCS) (or an equivalent European
  standard) will then be used after this period to
  accredited installers and technologies under CERT
  to ensure high standards for both technologies
  and installers are maintained.
• The UKMCS scheme has a range of technologies
  currently accredited and the majority of these
  can be funded by suppliers under CERT
• Working groups are currently developing the
  technical specifications for each technology with
  DEFRA.

16
Proposed key changes for CERT - Ofgem

• Microgeneration
• Where a saving cannot be established for a
  particular technology suppliers can have this
  measure approved under Demonstration Qualifying
  action
• Merton Rule suppliers schemes must be
  additional to the percentage of on-site
  renewables required by each individual local
  authority
• Suppliers are strongly encouraged to install
  all eligible insulation measures in a property
  before installing micro generation.
• CERT funding can be provided alongside LCBP and
  SCHRI schemes in England, Wales and Scotland
  suppliers only claim the percentage of savings
  they have funded

26
LCBP II and its implications for the second phase
of CERT

• Continuation of the LCBP accreditation list for
  year 1 as UKMCS is established
• All manufacturers and installers could play a
  part in the market by working with an energy
  supplier and are not eliminated for a one off
  tender process
• Technologies and products can change over the
  period of CERT giving flexibility for the MG
  market to grow and develop
• Funding will be based on the carbon saving
  potential of the technology and will favour
  biomass and ground source heat pumps

• Background
• Field Trial Objectives
• Data Collection and Analysis
• Project Timeline

31
EST Heat Pump Field Trials

• Background
• EST has experience developing and managing
  monitoring projects of energy efficiency
  installations in domestic households
• Insulation ventilation rates condensing
  boilers low-energy lighting domestic hot water.
• Micro-wind field trials
• Results have been used to set energy savings for
  lighting and insulation in SOP/EEC/CERT.
• The key objective of all EST monitoring work is
  to inform the consumer.

EST Heat Pump Field Trials

• 3 Key Objectives
• To illustrate the factors that influence the
  performance of in-situ domestic heat pumps.
• To determine the level of energy consumption,
  heat generation, and associated carbon savings in
  real installations (Measured by SPF and COP).
• To illustrate the customer experience and
  perceptions of the technology.

34
EST Heat Pump Field Trials

• Scope of Field Trials
• Include both ground and air source installations.
  
• Include a wide range of installation scenarios
  (based on property type household geographic
  distribution, etc.)
• Include a range of manufacturers products.
