buildings and the phase-out of inefficient
fuel-based lighting.

Building Energy Codes
Mandatory building energy codes and minimum
energy performance requirements
Governments should require all new buildings, as well as buildings
undergoing renovation, to be covered by energy codes and to meet
minimum energy performance requirements (MEPs) that aim to
minimise life-cycle costs. Energy codes and MEPs should be enforced,
regularly strengthened and take a holistic approach that includes the
building envelope and equipment.

New Buildings
Blocks of Flats
160 dwellings

Passive House Technology
15 kwh / m² per year
Payback = 9 – 10 years
Buildings stay
for 50 – 100 years !

Aiming for net zero energy consumption in
buildings
Governments should support and encourage the
construction of buildings with net zero energy
consumption and take initiatives to make such
buildings commonly available in the market when
economically viable based on a life-cycle cost
analysis.
Policies should include:
 Objectives for market share of net zero energy
consumption buildings in all new construction by
2020.
 The use of net zero energy consumption buildings
as a reference for mandatory MEPs in future
updates of building codes.
© OECD/IEA 2011
Improving the energy efficiency of existing
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 renovations.
Policies should include:
 An ambitious timeline and renovation rate for cost-effective reduction of
the energy consumption in existing buildings.
 MEPs for the building as a whole, including key building-envelope
components and energy-using systems, to be met during renovations.
© OECD/IEA 2011
Building energy labels and certificates
Governments should require
building energy performance labels
or certificates that provide
information to owners, buyers and
renters.
© OECD/IEA 2011
Package of policies for windows
and HVAC products
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 overall energy performance of new
and existing buildings.
© OECD/IEA 2011
Do it right in the first place
Specify high performance envelope
Assess optimal building size and use
Maximize passive HVAC and daylight
Consider building orientation, shape,
thermal masse
Install efficient equipment

• All countries have developed and implemented new energy
efficiency policies
• Energy savings opportunities still exist.

The IEA Policy Pathways
© OECD/IEA 2011
Current IEA work program on
buildings
 Global buildings energy policies
trends
 Worldwide mapping of building
policies
 Estimation of energy savings potential
per country
 Policies and Technologies for low
energy buildings
© OECD/IEA 2011
Key messages
 Work together (industry, policy-makers,
academia, NGOs)
 Share proven practices (developing countries,
emerging economies, developed countries)
 But don’t copy/paste
 Make buildings energy efficiency part of the
solutions to local/national priorities
 Consider local climate, material & behaviour
