IEA Recommendations EPBD Requirements
IEA Recommendation EPBD Requirements
2.1: Mandatory building energy code and minimum performance requirements (MEPs)Governments should require all new buildings, as well as buildings undergoing renovation to features covered by the codes, to meet minimum energy performance requirements (MEPs) that aim to 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 efficiency of existing buildingsGovernments 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.

Article 20: Information

IEA Recommendations EPBD Requirements
IEA Recommendation EPBD Requirements
• Policies and measures to aid building owners and occupants to improve energy efficiency in existing buildings, such as:
• Energy audits, energy ratings and certification schemes
• Incentives to encourage investments in long lasting building envelope and system improvements, and increased market penetration of new high efficiency products;
• Training and other measures to improve the quality and reliability of building retrofit services;
• Information on financing options;
• A strong commitment by governments to improve the efficiency of public sector buildings.

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.
© OECD/IEA 2011
IEA Recommendations EPBD Requirements
IEA Recommendation EPBD Requirements
• Minimum energy performance (overall heat transfer coefficient) requirements for windows and other glazing that 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 provid e 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.
Article 4: Setting of minimum energy performance requirements
© OECD/IEA 2011
IEA Recommendations EPBD Requirements
IEA Recommendation EPBD Requirements
• Mandatory minimum energy performance requirements for HVAC equipment and systems that are designed to minimize 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.
