EPBD

• The Energy Performance of Buildings Directive was
  approved by the European Parliament on December
  16, 2002.
• By January 4, 2006 the following will be
  implemented
• Methodology for calculating energy performance of
  buildings
• Energy performance requirements for new and
  existing buildings
• Certification system for energy performance of
  buildings.
• Methodology for inspection of boilers and
  air-conditioning systems.
• For items 3 and 4, an additional period of three
  years can be
• given to fully comply with the directive (i.e.
  article 15).

3
New buildings (article 5)

• Buildings shall meet the minimum energy
  performance requirements (article 4)
• Buildings with a total useful floor area gt1000 m2
  must ensure that the technical, environmental and
  economic feasibility of alternative energy
  systems are considered and taken into account
  before construction starts.

4
Existing buildings (art. 6)

• Buildings with a total useful floor area gt1000 m2
  undergoing a major renovation shall be upgraded
  in order to meet minimum requirements in so far
  as this is technically, functionally and
  economically feasible.

5
Energy performance certificate (art. 7)

• A building energy certificate for all buildings
  to be constructed, sold or rented out must be
  made available to the owner or by the owner to
  the prospective buyer or tenant. The validity of
  the certificate shall not exceed 10 years.
• The objective of the certificate shall be limited
  to the provision of information and any effects
  of these certificates in terms of legal
  proceedings or otherwise shall be decided in
  accordance with national rules.

6
Inspection of boilers (art. 8)

• The intention is to reduce energy consumption and
  to limit CO2 emissions .
• National systems for either (a) inspection or (b)
  assessment shall be implemented
• The overall impact of approach b) should be
  broadly equivalent to that arising from the
  provisions set out in a). Member states that
  choose option (b) shall submit a report on the
  equivalence of their approach to the Commission
  every two years.

7
Inspection of air- conditioning systems (art. 9)

• The intention is to reduce energy consumption and
  to limit CO2 emissions.
• National systems for inspection of
  air-conditioning system of an effective rated
  output gt 12KW will be established.
• The inspections shall include an assessment of
  the air-conditioning efficiency and sizing
  compared to the cooling arequirements of the
  building.

8
Independant experts (art. 10)

• National systems will enable
• Certification of building energy efficiency
• Drafting of accompanying recommendations
• Inspection of boilers
• Inspection of air-conditioning systems
• to be carried out in an independant manner by
  qualified and/or accredited experts, whether
  operating as sole traders or employed by public
  or private enterprise bodies.

9
Transposition (art. 15)

• Member States may, because of lack of qualified
  and/or accredited experts, have an additional
  period of three years to apply fully the
  provisions of Articles 7, 8, and 9.
• When making use of this option, Member States
  shall notify the Commission, providing the
  appropriate justification together with a time
  schedule with respect to the further
  implementation of this Directive.

10
Implementation in Norway

• The Ministry of Ministry of Local Government and
• Regional Development is responsible for
• implementing
• Methodology for calculating energy performance of
  buildings
• Requirement for energy performance in new
• and existing buildings
• Implementation will mainly be through amendments
• to Technical Regulation under the Planning and
• Building Act of 1997 (TEK). The task has been
• delegated to the National Office of Building
• Technology and Administration (BE).

11
Energy performance

• Proposed (2006) requirements of buildings kWh/m2,
  per year

• Total annual energy saving for new buildings will
  after the implementation of the new requirements
  be at least 250 GWh. After 10 years about 2,5 TWh
  will be saved. Most likely the redused energy
  requirement will be much higher because the
  estimate does not include existing buildings.

12
Energy performance

• Proposed (2006) requirements of buildings

• The efforts used to achieve more energy efficient
• buildings compared with existing regulations are
• Insulation lower u-value for windows
• Infiltration higher tightness
• Ventilation
• Lower SFP
• Heat recovery in residential buildings
• Higher demands on energy efficiency for heat
  exchangers
• Demand controlled room-temperature
• The abovementioned efforts are considered
• profitable.

13
Implementation in Norway

• The Ministry og Petroleum and Energy (OED) is
• responsible for the implementation of
• System for certification of energy performance of
  buildings
• The task has been delegated to Enova
• System for inspection of boilers and
  air-conditioning systems
• The task has been delegated to NVE

14
Certification system Mandate(Enova)

• First attempt to create a system for
  certification of new and existing buildings
• Implement a system that forms a complete
  information strategy on redused energy
  performance in buildings
• First draft ready February 2004, final draft
  summer of 2004.

15
Certification system Criteria(Enova)

• Make building energy consumption and expected
  energy costs visible
• Consider Norwegian needs in addition to the
  Directive
• Give information on energy flexibility, energy
  carrier and the buildings impact on its
  environment
• Understandable and user-friendly presentation of
  the information
• The information must be consistent and of high
  quality
• The system must be simple and cost effective to
  carry out and to administer
• Complete guide for new/existing buildings and for
  small/large buildings
• The information is registered and systemised to
  enable it to be transferred to a national
  database.

16
Certification system - Organization (ENOVA)

• The system needs to be simple and cost effective
  to administer, OED is its highest authority
• Avoid build-up of unnecessary public bureaucracy
• Operating tasks related to the organization need
  to be appropriate for competition
• The system should be made a natural part of the
  building process in order to give it the right
  status to be actively used by the construction
  industry to achieve better energy performance in
  buildings
• Qualification of independent experts existing
  systems administered by the National Office of
  Building Technology and Administration (BE) might
  be used or adapted
• Start with new buildings and phase in existing
  buildings as competence increases.

17
Labelling of residential buildings
Energy performance of new residential buildings
has mostly been overlooked, and there is little
focus on marketing residential buildings with low
energy performance. Enova proposes to implement
a voluntary framework for labelling of energy
performance, which will market residential
buildings with low energy performance. The
labelling will be based on the same philosophy as
EUs energy performance label (for example for
appliances), which has been very successful.
18
The future process (ENOVA)

• Draft for the system handed over to OED as basis
  for further internal work
• Coordination between BE, Enova, NVE and Standard
  Norway
• Future activities
• Creation and testing of certificate
• Survey of environmental factors
• Development of tools
• Development of organization model
• Assess postponement of parts of the project

19
The future process (BNL/NVEF)

• Official presentation of systems for
  implementation of EPBD for the industry before
  summer 2004
• Integration in the industry through active
  cooperation /reference groups

20
Expectations(ENOVA/ BNL/ NVEF)

• It is important to develop systems with a broad
  acceptance which are regarded as sensible and
  informative by developers, investors and tenants.
• Such systems will contribute to the development
  of buildings with better energy performance and
  increased flexibility.
• A well adapted system will be an important
  contribution to reach national goals for better
  energy performance and flexibility.
