covered by the codes, to meet
performance requirements
minimum energy performance
requirements (MEPs) that aim to Article 6: New buildings
minimise life-cycle costs. These MEPs
should be enforced, regularly
strengthened and take a holistic
approach that includes the building
envelope and equipment.

2.3: Improving the energy Article 7: Existing buildings
efficiency of existing Article 20: Information
buildings
Governments should implement a package of
policies to improve the energy efficiency of
existing buildings, with emphasis on significant
improvements to building envelopes and
systems during major renovations.
Policies should include:
•An ambitious timeline and renovation rate
for cost effective reduction of the energy
consumption in existing buildings;
•Mandatory minimum energy performance
requirements for the building as a whole,
including key building envelope components
and energy-using systems, to be achieved
during renovations of existing buildings.

• Energy audits, energy ratings and Article 15: Inspection of air-
certification schemes conditioning systems
• Incentives to encourage investments in
long lasting building envelope and system Article 16: Reports on the
improvements, and increased market inspection of heating and air-
penetration of new high efficiency conditioning systems

IEA Recommendation EPBD Requirements
2.5: Energy performance of
building components and
systems
Governments should establish policies
to improve the energy efficiency
performance of critical building
components, such as windows, and
heating, ventilating and cooling systems,
in order to improve the energy
performance of new and existing
buildings.
Specifically, governments should
implement a package of policies to
improve the overall energy performance
of windows and other glazed areas.

10. IEA Recommendations
EPBD Requirements
IEA Recommendation EPBD Requirements
• Minimum energy performance (overall
heat transfer coefficient) requirements
Article 4: Setting of minimum
for windows and other glazing that energy performance requirements
minimise lifecycle costs;
• Performance-based requirements or
guidelines that identify the maximum
share of glazed area that is appropriate
for specific building types.
• A requirement for window and glazed-
product manufacturers to provide
performance labelling, based on
standard test protocols and certified
product testing;
Set up a policy package to reduce
energy demand of heating,
ventilation and air-conditioning
(HVAC) systems.

11. IEA Recommendations
EPBD Requirements
IEA Recommendation EPBD Requirements
• Mandatory minimum energy performance
requirements for HVAC equipment and
Article 8: Technical building
systems that are designed to minimize systems
lifecycle costs;
• A requirement for HVAC product
manufacturers to provide energy efficiency
labelling and further energy efficiency
information for their products; and
• Information and training for building
designers, owners and others to ensure
that HVAC systems are appropriately
sized, installed, tested, and maintained so
as to maximize building energy
performance at least life cycle costs.
• Promote energy management and control
systems to reduce energy consumption
and better target energy-saving
opportunities.
