  1. nZeh working towards net zero energy affordable homes Information session on Energy Efficiency in the Building Sector 7th October 2013

  2. nZeh a collaborative research project bringing together stakeholders in the sectors of Building construction Sustainable development to design, implement and monitor a prototype affordable near net-zero energy residential home

  3. What is a net-zero energy home? An energy efficient, grid connected unit enabled to generate energy from renewable sources to compensate its own energy demand so that its net energy consumption is ZERO.

  4. Through the study of a new build prototype affordable home, the cost implications and potential for energy efficiency within the local context is better understood. nZeh will help advance the industry’s knowledge and assist with both new constructions, retrofitting of existing buildings and the achievement of near self-sufficiency at district level where possible. LOCAL CONTEXT…….

  5. In 2005 homeownership rate was at 75.2% ……This has led to above normal housing price growths and a supply that exceeds the needs…… Camilleri, D., A Long-term Analysis of Housing Affordability in Malta, 2010, Emerald 72,150 vacant dwellings Malta Today, 7th July 2013

  6. At-risk-of-poverty at 15% and increased by 1.5% compared to 2005 Ministry for European Affairs, Programming of European Funds for Malta 2014 2020, Public Consultation Document, 2013, pg.8 Affordable housing costs should not exceed 35% of gross household income Camilleri, D., A Long-term Analysis of Housing Affordability in Malta, 2010, Emerald Affordable property rate in 2008 was 508 Lm/m² (1184 €/m²) Camilleri, D., A Long-term Analysis of Housing Affordability in Malta, 2010, Emerald In 2002 10 – 40% of households had affordability problems Structure Plan for the Maltese Islands, Housing Topic Paper, 2002, pg. 56 cl. 2.2.86

  7. 2020 national energy targets max 5% increase in GHG emissions compared to 2005 levels 10% of energy from renewables 22% or 0.24 Mtoe reduction in primary energy European Comission, http://ec.europa.eu/europe2020/pdf/targets_en.pdf

  8. 35% Domestic Said, G., 2013, Electricity Consumption in Households, Energy Efficiency Initiatives Conference 10.7% of households use renewable sources Said, G., 2013, Electricity Consumption in Households, Energy Efficiency Initiatives Conference In 2009 only 0.016% of the total electricity generation was produced from renewable sources Yousif, C. 2012, Maltese Environmental Law An Introduction, Session 5 Renewable Energy

  9. Legislation Policies Goals PL Electoral Manifesto, 2013 Ministry for Resources and Rural Affairs, 2009, A Proposal for an Energy Policy for Malta Ministry for Tourism, the Environment and Culture, 2012, National Environment Policy, Progress Press Strategic Plan for the Environment and Development (SPED), 2012 Programming of the European Funds for Malta 2014 2020, Public Consultation Document, 2013 DIRECTIVE 2002/91/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 16 December 2002 on the energy performance of buildings L.N. 376 of 2012 BUILDING REGULATION ACT (CAP. 513) MALTA RESOURCES AUTHORITY ACT (Cap. 423) Energy Performance of Buildings Regulations, 2012 • New buildings should meet minimum energy performance requirements • Major renovations of existing buildings above a certain size should be regarded as an opportunity to take cost effective measures to enhance energy performance. • By 2020 all new buildings will be designed to consume zero net energy • Improve quality of urban areas • Promotion of energy efficiency in dwellings and implementation of more energy efficient buildings • Providing professional advice regarding methods and ways to reduce energy consumption in dwellings

  10. Project Objectives • Provide direction and assistance in meeting international obligations • Encourage development of affordable housing • Raise standards of housing provision for a better quality of life • Tackle energy poverty

  11. Project Participants Kamratal-Periti Housing Authority The Institute for Sustainable Energy The Faculty for the Built Environment Building Industry Consultative Council Ministry for Energy and Conservation of Water Malta Environment and Planning Authority Malta Developer’s Association Malta Resources Authority Architecture Project Other Consultants (Building Services Engineers, Environmental Engineers, Economist, Sociologist, Communications & Marketing strategist)

  12. Approach

  13. Estimated Potential Savings Anticipated electrical energy consumption in 2013 – 2,937,000 MWh, Enemalta Corporation, Electricity Generation Plan 2006-2015 Domestic sector responsible for 35% of energy consumption - 1,030,000 MWh If 10% of dwellings are zero energy – 10% saving Potential energy savings of 103,000 MWh per year

  14. Atika is part of Velux Group’s efforts to strengthen relations with strategic partners in the construction sector, to initiate discussions on issues such as future housing concepts, healthy buildings and sustainable city development… Home for Life, VKR Holdings…..With Home for Life, VKR Holding aims to bring carbon-neutral houses to the masses Soleta zero Energyrepresents, The Foundation for Inventions and Sustainable Technologies – Justin Capra…In order to introduce you to this revolutionary concept, we built SoletazeroEnergy One prototype The HOUZE corporate team, a public-private partnership with the city of Houston, is comprised of third-generation builders, developers and marketers with combined expertise in all aspects of housing, energy, technology and real estate development.

  15. ATIKA ...for Mediterranean climates Daylighting Passive heating in winter Insulation Shading screens Natural controlled ventilation Orientation and positioning of windows Solar water heating, space heating and space cooling

  16. Benefits • Direct cost savings from lower energy consumption • Better environment and quality of life • Owners of low energy houses value the non-energy benefits even more than the cost savings themselves • better air quality • higher comfort levels • a better house - easier to sell • taking responsibility for the environment and future generations
