    • Building Codes Project WORKSHOP CONSTRUÇÃO SUSTENTÁVEL “ CICLO DE VIDA DOS EDIFÍCIOS (SUSTENTABILIDADE E RESILÊNCIA) APA - 21/01/2010 Building Codes Project
    • Project team Building Codes Project Project Coordinator: Rui Vinhas da Silva (Associate Professor) Alexandre Fernandes Paulo Santos MBA project experts: Manuel Casquiço Anshuman Bhardwaj Dionis Arvanitakis André Silva (IST) Subramanian Parameswaran Building Codes Project
    • Data Base Analysis And Energy Efficiency Measures - for the Portuguese Residential Buildings Building Codes Project
    • Contents Information obtained from the Database Analysis  Current Energy Classification  Building classification by decade Identifying the Top Energy Efficiency Measures:  Quantitative analysis  Qualitative analysis Top Energy Efficiency Measures  Impact on energy classification Portugal-Market Drivers & Constraints Self Perpetuating cycle of imbalance Building Codes Project
    • Database Overview The database includes around 100,000 valid certificates. • Urban Apartment • Up to 3 floors building • T3 tipology • Over 110m2 • C class energy certification Building Codes Project
    • Currently 40% of the certified buildings have at least B- as its energy classification Energy Class Percentage of buildings per Energy Total certificates: 80,903 Class Building Codes Project
    • Relatively the highest inefficiency level lies in the 70’s % building energy class per decade 4,000 50% 50% 3,500 3,000 40% 40% 2,500 Number building 30% 30% certificates 2,000 per decade 1,500 20% 20% 1,000 10% 10% 500 0 0% 0% E F G A+ B B- C D E F G A+ A B B- C D E F G A+ A B B- C D E F G A+ B B- C D E F G A+ A B B- C D E F G A+ A B B- C D E F G B B- C D E F G A+ A B B- C D E F G 1950-1959 1960-1969 1970-1979 1980 - 1989 1990 - 1999 Building Codes Project
    • The energy efficiency of houses from current decade have improved and continue to improve % building energy class per decade 20,000 18,000 50% 16,000 40% 14,000 12,000 30% 10,000 Number building certificates 8,000 per decade 20% 6,000 4,000 10% 2,000 0 0% A+ A B B- C D E F G A+ A B B- C D E F G 2000-2005 2006-2009 Building Codes Project
    • Data Analysis – Outcome Experts recommendations focus on domestic hot water, insulation and solar systems Building Codes Project
    • Applying all the energy efficiency measures will result in 85% of the buildings being classified with at least B- Current Energy Post Classification implementation of EE measures EFFICIENCY MEASURES Building Codes Project
    • Technology and Environmental Analysis-PORTUGAL Analysis of Portuguese Technology and Environmental System Current Strengths Current Challenges  Focus on renewable energy  Difficulty in meeting EU stipulation  Building certification  Promotion policies for renewable technologies are not attractive for Portuguese consumers Future Prospects Future Challenges  Solar energy initiatives  Failure to meet Kyoto targets  Funding of environmentally friendly  Household income technologies Building Codes Project
    • Market Drivers and Constraints Building Codes Project
    • Economic/Financial Incentives for residential buildings Reducing the gap between the European and Portuguese practices in the field Building Codes Project
    • Subsidies act as policy instrument to help incentivize end consumers Beneficiarie Types s • Direct subsidies to the • End-use consumers private sector • Companies • Tax incentives • Mixed • Loans • Direct subsidy to the public sector • Feed-in Tariff • Other Building Codes Project
    • Heating and Insulation are the main focus of the financial incentives in Europe EE product s, 8% Heat pumps, 9% Boilers, 8% Water heating Refurbishment Ventilation 11% 5% 11% Lighting Heating, 22% Others, 21% 11% Glazing 26% Related EE labour cost Lowenergy 10% houses 16% Insulation, 25% Energy audit 10% Renewable energy, 6% Detailed distribution of the 21% As a percentages of the total incentives (Others) evaluated Building Codes Project
    • An isolated Financial incentives programme won’t generate the expected result • Generally, countries adopt a combination of financial incentives programmes. • Financial support is not the only focus of Governmental incentives. Educational campaigns and research and development also represent a main focus of the funds available for EE. • Requirements generally include an energy saving estimation of the measure to be implemented by a third party. Building Codes Project
    • Subsidies program should be segmented to address the EE measures of old buildings 8 Norway 1) Different levels of 7 UK segmentation are applied 6 Slovenia among countries to 5 France concentrate their efforts in 4 Ireland Austria supporting specific building 3 Romania Sweden Czech R. targets. 2 Denmark Belgium m d n u E a e z v c s r Finland Bulgaria H t i 1 ungary Germany 2) Different levels of supports 0 are provided to different EE 0 1 2 3 4 5 6 7 measures. Number of subsidy programs Building Codes Project
    • Besides products, additional items associated to EE are integral part of Tax incentives programmes in EU Building Codes Project
    • Financial instruments targeting a combination of EE products have proved to be more effective Less frequently applied EE instruments in Europe Heating Insulation 1)Countries like France, Germany have L energy houses ow created subsidized credit programs E appliances/ products E m u E Glazing a e s r 2)Some financial products are also H pumps eat combined with other instruments Boilers 0 1 2 3 4 5 3)An example from the US: EE Mortgages Numbers of Financial incentives programs in Europe Building Codes Project

    • Marketing Assessment - for the Portuguese Residential Buildings Building Codes Project
    • There is a gap between Intent and Action in Consumer Behaviour... Intent Action 75% of Portuguese consumers claim to worry “Have you bought an environmentally friendly product in about climate change and 59% believe that their the last month”, only 17% of the Portuguese energy usage causes climate change. consumers responded with a ‘Yes’, Source: Attitudes towards Energy, Special EUROBAROMETER 295/Wave 68.2-TNS Opinion & Social, (PORTUGAL-2008) Portuguese consumers are aware of the impact they can have on Energy Efficiency but have not really translated their deeds into actions Building Codes Project
    • The ‘gap’ affects the buyer decision process, thus hindering adoption of EE measures... Top-most reasons for the ‘gap’: Source: LOGICA (based on TNS/Future Foundation research), PORTUGAL-2007 •Thermal •Thermal •Thermal •Thermal Insulation, Insulation, Insulation, Insulation, •Glazing, •Glazing, •Glazing, •Glazing, •Solar Thermal •Solar Thermal •Solar Thermal •EE Air •Heat Pumps •Heat Pumps •EE Air conditioner •EE Air •EE Air conditioner Buyer Decision conditioner conditioner Process: Source: Marketing Management 13th Edition, Kotler and Keller Building Codes Project
    • Whilst there are positive market drivers that will help in the long term, current market constraints also need our focus in the short-term... Building Codes Project
    • There is a need to segment the market, before marketing of EE measures, because there exists, a varying ‘referencing’ behaviour of customers... Technology Adoption Lifecycle: Early Adopters Early Majority Late Majority Innovators “CHASM” Laggards ` > Time -- > Building Codes Project
    • Energy Efficiency Measures - for the Portuguese Residential Action points Buildings Alexandre Fernandes Building Codes Project
    • Current project, shows that energy efficiency in buildings will require a stronger focus in some priority key areas Equipments • Improve Solar thermal penetration • Increase the number Proposal of high efficiency boilers •Higher efficiency in • Improve energy Level of Energy Efficiency Implementation efficiency in residential climatization systems Sector; • Average savings of €514 Building Envelope /household in the annual energy bill • Insulation • Payback : from 6 to11 years • Glazing Level of Energy Efficiency Building Codes Project
    • Road map to get a higher efficiency level in buildings Incentives and grants •Reduce price gap between High and low efficient products • Follow EU best practices 1 out of 10 ISSUE buildings Increase Communications and Research to become energy • Market research addresing energy efficiency in consumer benefits efficient (*) • Above the line communications residential in buildings by 20% Value Chain 2015 • Product availability in new trade channels, eg.: - DIY stores/Hipermarkets • New “added value” services (*) : Over B- energy class Building Codes Project
