IEA Recommendations EPBD RequirementsIEA Recommendation EPBD Requirements2.1: Mandatory building Article 3: Adoption of aenergy code and minimum methodology for calculating theperformance requirements energy performance requirements(MEPs) Article 4: Setting of minimumGovernments should require all new energy performance requirementsbuildings, as well as buildings Article 5: Calculation of cost-undergoing renovation to features optimal levels of minimum energycovered by the codes, to meet performance requirementsminimum energy performancerequirements (MEPs) that aim to Article 6: New buildingsminimise life-cycle costs. These MEPsshould be enforced, regularlystrengthened and take a holisticapproach that includes the buildingenvelope and equipment. © OECD/IEA 2011

  • 6. IEA Recommendations EPBD RequirementsIEA Recommendation EPBD Requirements2.3: Improving the energy Article 7: Existing buildingsefficiency of existing Article 20: InformationbuildingsGovernments should implement a package ofpolicies to improve the energy efficiency ofexisting buildings, with emphasis on significantimprovements to building envelopes andsystems during major renovations.Policies should include:•An ambitious timeline and renovation ratefor cost effective reduction of the energyconsumption in existing buildings;•Mandatory minimum energy performancerequirements for the building as a whole,including key building envelope componentsand energy-using systems, to be achievedduring renovations of existing buildings. © OECD/IEA 2011 
  • 7. IEA Recommendations EPBD RequirementsIEA Recommendation EPBD Requirements• Policies and measures to aid building owners and occupants to improve energy Article 14: Inspection of heating efficiency in existing buildings, such as: systems• 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 products;• Training and other measures to improve Article 17: Independent experts the quality and reliability of building Article 18: Independent control retrofit services; systems• Information on financing options; Article 10: Financial incentives and• A strong commitment by governments to improve the efficiency of public market barriers sector buildings. © OECD/IEA 2011 
  • 8. IEA Recommendations EPBD RequirementsIEA Recommendation EPBD Requirements2.4: Building energy labels or Article 11: Energy Performancecertificates certificatesGovernments should require building Article 12: Issues of energyenergy performance labels or certificates performance certificatesthat provide information to owners,buyers and renters.

  • 9. IEA Recommendations EPBD RequirementsIEA Recommendation EPBD Requirements2.5: Energy performance ofbuilding components andsystemsGovernments should establish policiesto improve the energy efficiencyperformance of critical buildingcomponents, such as windows, andheating, ventilating and cooling systems,in order to improve the energyperformance of new and existingbuildings.Specifically, governments shouldimplement a package of policies toimprove the overall energy performanceof windows and other glazed areas. © OECD/IEA 2011 
  • 10. IEA Recommendations EPBD RequirementsIEA 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. © OECD/IEA 2011 
  • 11. IEA Recommendations EPBD RequirementsIEA 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. © OECD/IEA 2011
