Regional workshop WEC-ADEME “Evaluation of Energy Efficiency Policies in the MENA Region” organised by ANME with the support of UNDP Tunis, 15-16 March 2010 Compliance on Energy Building Codes Adel Mourtada EnergyEfficiency Expert ECOTECH Lebanon
1- Importance of energy efficiency in buildings in Southern MEDA countries
Building code Principal tool to reduce energy consumption in new buildings • • In Europe and USA : Long tradition with using building codes to ensure policy targets. • Building codes essential tool in Policy Mix to ensure energy efficiency of new buildings. • Building codes sets targets for buildings industry. • All MEDA countries have (or have started development of) thermal building code.
Perceptive approach: Compliance check • • Focus on component minimum acceptable performance • – Pass/fail criterion for one parameter per component • • Usually U-value • • Manufacturers can often certify performance of material and component. • – Plus inspection on site for construction phase.
Advantages of prescriptive approach • • Easy to apply • – Generally preferred by designers of small buildings • • Requires relatively little information • • Easily applicable to minor renovation • • Relatively easy to check
Whole-Building energy performance compliance path • • Move towards integrated, inclusive calculation • – All fixed services (lighting, heating, cooling, ventilation) • • More complex to apply • – More information to obtain • – Usually requires computerised calculation • • Easier to • – Make a mistake • – Hide an incorrect figure • • More difficult to check!
Tunisia Performance Approach Self certification supervised by accredited assessor Prescriptive Approach Self Certification By Architect or BE Building Permit Commission of permit Check of compliance
Turkey Private Building Self certification supervised by accredited control Engineer Public Building Self Certification Prepared by public Agency (Ministry of Housing) Building Permit Commission of permit Check of compliance
Turkey Private Building Inspection of construction by certified control Engineer Public Building Inspection of construction by Ministry of Housing Parallel inspection by Municipality If Compliance occupancy permit
37 Producers 92 Suppliers 16 Installers Thermal insulation market development • Enforcement of TS 825encourages the development of The market of insulation materials and widows double glazing Insulation material sales increase by 230% in three years (source ISOCAM) Prices decrease IZODER - Thermal Insulation. Water Proofing. Sound Insulation and Fire Protection
5- Status of enforcement and reasons for non-compliance in MEDA Region
Reasons For Non-Compliance • Municipal staff and building official have no history with Thermal Insulation Standards: • - Need to develop compliance infrastructure (responsibilities schemes, training…). • Manufacturers have no product rating systems: • Need to develop national energy rating systems for building envelope (windows) & Insulation materials… • Subsidies for energy prices. High pay back period. Owners have no interest to invest in insulation. • Need to move from bad subsidies to good subsidies • • Architects and Mechanical Engineers don’t have sufficient knowledge on energy efficiency building code. Installers don’t have practical knowledge of insulation technologies. • – Need infrastructure for training installers, engineers and for accrediting assessors and inspectors.
6. Conclusions • - The fact of having thermal building codes does not automatically lead to market change and to energy efficiency in buildings. • - Good implementation approach is based on a strict control scheme and should be well supported by the stakeholders. • - Such strict control scheme requires very substantial supporting measures. • - Government should start to monitor compliance (especially for public buildings).
6. Conclusions • Building official are more likely to check compliance and inspect construction if the have training. • Designers and construction companies are more likely to comply with the code if they know that everyone else must. • Manufacturers will provide energy-efficient products if they know that there is a sure market due to code enforcement. • Owners and developers are more likely to invest in Energy efficiency measures if they know that energy prices are going to increase in the future and if they there are subsidies for thermal insulation.
