5 21-22 September EU Regulation within building sector targets targets –A reduction in EU greenhouse gas emissions of at least 20% below 1990 levels –20% of EU energy consumption to come from renewable resources –A 20% reduction in primary energy use compared with projected levels, to be achieved by improving energy efficiency. Energy Performance of Buildings Directive A key part of this legislation is the Energy Performance of Buildings Directive (EPBD) which requires all EU countries: –to enhance their building regulations –to introduce energy certification schemes for buildings –to have inspections of boilers and air-conditioners.

6 21-22 September EU Regulation within building sector Energy Performance of Buildings Directive 2002 Directive 2002/91/EC of the European Parliament and of the Council of 16 December 2002 on the energy performance of buildings Eco-design of Energy-using Products Directive 2005 DIRECTIVE 2005/32/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 6 July 2005 establishing a framework for the setting of ecodesign requirements for energy-using products Energy End-use Efficiency and Energy Services Directive 2006 DIRECTIVE 2006/32/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 5 April 2006 on energy end-use efficiency and energy services Eco-design 2009 Directive 2009/125/EC of the European Parliament and of the Council of 21 October 2009 establishing a framework for the setting of ecodesign requirements for energy-related products Recast of EPBD 2010 DIRECTIVE 2010/31/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 19 May 2010 on the energy performance of buildings (recast)

7 21-22 September Recast of EPBD 2010 The aim of the recast is to clarify, strengthen and extend the scope of the current directive, as well as to reduce the large differences between Member States' practices in the building sector. Overall, its provisions cover energy needs for space and hot water heating, cooling, ventilation and lighting for new and existing, residential and non-residential buildings. 1.Key legal requirements of the new directive 2.Minimum energy performance 3.New, existing & 'Nearly zero energy' buildings 4.Energy performance certificates (EPCs) 5.Financial incentives and market barriers 6.Inspection of boilers and air conditioning systems 7.Public awareness and communication 8.Penalties for non-compliance FROM EPBD 2002

8 21-22 September EPBD 2010 and COOL-Coverings The methodology for calculating energy performance should be based not only on the season in which heating is required, but should cover the annual energy performance of a building. That methodology should take into account existing European standards (9) Methods for computing energy are addressed by Directive 2009/125/EC of the European Parliament and of the Council of 21 October 2009 (ECODESIGN) and Directive 2010/30/EU (energy- related product) (12) Not only new building (15) Particular attention to public building (24) Priority should be given to strategies which enhance the thermal performance of buildings during the summer period (25) Training for installers and builders

9 21-22 September EPBD 2010 and COOL-Coverings Article 2: […] Mandate to CEN for development of standard Article 5 The Commission shall establish […] by 30 June 2011 a comparative methodology framework for calculating cost- optimal levels of minimum energy performance requirements for buildings and building elements Article 9 – Nearly zero-energy buildings: MS shall ensure – by 31 December 2020, all new buildings are nearly zero- energy buildings; and –after 31 December 2018, new buildings occupied and owned by public authorities are nearly zero-energy buildings. ANNEX 1 Common general framework for the calculation of energy performance of buildings –The methodology for calculating the energy performance of buildings should take into account European standards and shall be consistent with relevant Union legislation, including Directive 2009/28/EC. –The methodology shall be laid down taking into consideration at least the following aspects: […] insulation, cooling elements

10 21-22 September EU Regulation for nanotechnology Resolution (2008/2208(INI) Nanomaterials European Parliament resolution of 24 April 2009 on regulatory aspects of nanomaterials NANOCODE of conduct C(2008)424 code of conduct for responsible nanosciences and nanotech-research Towards a European Strategy for Nanotechnology /actionplan.htm Directive 89/391/EEC Council Directive 89/391/EEC of 12 June 1989 on the introduction of measures to encourage improvements in the safety and health of workers at work Regulation (EC) No 1907/2006 Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), establishing a European Chemicals Agency NanoGeneric products

11 21-22 September NANOSAFE aims at developing risk assessment and management for secure industrial production of nanoparticles. (16/11/2010, Grenoble, France Nanosafe2010 International Conference on Safe production and use of nanomaterials) Regulation on nano for COOL-Coverings Scientific Committee On Emerging And Newly Identified Health Risks (SCENIHR) identified some specific health hazards as well as toxic effects on environmental organisms for some nanomaterials. SCENIHR furthermore found a general lack of high-quality exposure data both for humans and the environment, concluding that the knowledge on the methodology for both exposure estimates and hazard identification needs to be further developed, validated and standardised, The Commission is called upon to compile before June 2011 an inventory of the different types and uses of nanomaterials on the European market, to make this inventory publicly available and to report on the safety of these nanomaterials.

19 21-22 September Summary Eu Regulation –Within building sector –With relevance for COOL-Coverings –Within Nanotechnology sector Standard –EU mandate to CEN –Work sheet for Cool-coverings Patent search and innovative ideas

20 21-22 September Patent search First set of searches and patent analysis We have used the following Keywords: Insulation system, energy efficiency, envelope, coverings, ceramic tiles, coatings, paints, roof, nanotechnologies + NIR concept Ventilated facades

21 21-22 September Preliminary results for T1.1 Patent analysis We have made some general considerations –big gap between patents for traditional insulation and nano- based method –more nano patents in paints and coatings than tiles –Lots of innovations from far east (and Spain for tiles)

22 21-22 September Patent search refinement On the basis of a review of literature and considering patent search results we are identifying the most promising ideas and innovative products: –Infrared Reflective Inorganic Pigments, Ashwini K. Bendiganavale and Vinod C. Malshe (Retd) Prof. Paints Technology, University Institute of Chemical Technology, Matunga, Mumbai, , India –Energy-efficient house with IR barriers - in form of roof-space and wall layers –Pigments which reflect infrared radiation from fire, fire retardant –Selective emissivity coatings for interior temperature reduction of an enclosure –Coatings having low emissivity and low solar reflectance –Low-emissivity window films and coatings incorporating nanoscale wire grids –[…]

23 21-22 September Innovative ideas We have listed some examples of interesting ideas and technologies for paints and coatings DUPONT SolarCOOL INDEX SPA Construction System and Products Cool roofing material Database m#white%20coatings

24 21-22 September Innovative ideas od85.html od85.html As a Radiant Barrier: Stops heat from entering or escaping. Hy-Tech Barrier Coat is the ONLY radiant barrier paint that contains pure metal (aluminum) pigment, Hy-Tech insulating ceramic microspheres and NO mineral spirits or other volatile, flammable solvents. How It Works: Aluminum is highly reflective to infrared (IR) due to the high concentration of mobile electrons. Barrier Coat contains aluminum metal in the form of thin "Leafing" aluminum flakes which are highly reflective and reduce the penetration of IR radiation. reflective-paint.html reflective-paint.html "It's just unbelievable, we no longer have to wear wet scarves around our necks. It's now very comfortable." And testing confirmed the reason why. The underside of the uncoated roof recorded a massive 55.8°C. The underside of the roofing area coated with Insultec reflective paint measured 38°C. The product we use also CONTAINS NO CERAMICS which can break down quickly. The reason is simple. Insultec's Solar Cool heat reflective paints are made of a co-polymer compound containing inert pigments and special filters uniquely formulated to re-radiate 90% of solar infrared and 85% of ultraviolet rays back into the atmosphere, effectively stopping heat transfer through the roof. Depending on location, some industrial and commercial buildings will also benefit from applying Insultec's high insulating reflective paint to exterior walls to achieve a maximum reduction of heat transferring into the building. 24

25 21-22 September Innovative ideas coatings.htm coatings.htm IPS has developed paints and coatings for building applications, which reflect significantly more solar energy than standard paints with the same colour. This means less heat is lead into the house and finally less heat must be compensated by the air conditioning. Besides the aspect of energy saving the coating itself does not become as hot as standard paints, and this will increase the lifetime of the coating.

26 21-22 September Innovative ideas RLHY-13 Solar Reflective Heat insulating roof coating –RLHY-13 belongs to one type of the energy-saving thermal insulation coating, Its inorganic water-based paint, has a white slurry shape. After solidifying, its specific gravity only 0.46g/ml. –RLHY-13 is new heat-reflection thermal insulation coating, has features of heat insulation, waterproof, fire prevention, anti-corrosion. Heat reflection rate more than 90%, could reflect a lot of infrared. This coating has a thermal conductivity of 0.04W/m.K,so could prevent the infrared from heating the object and inhibit the thermal conduct from the sun and the infrared, then have a thermal insulation rate 90%. Application –Reduce oil tank's surface temperature about 30% –hot pipes to heat insulation,waterproof,anti-leakage. –on metal to prevent the metal from react with air and water, and prevent the metal from corrosion. –prevent condensation. –for thermal insulation purpose,could save 90% of losted energy. –Paint on the outdoor equipment, its waterproof and thermal reflection, reduce the temperature of the equipment.

27 21-22 September Innovative ideas Surf Cool can slow rising temperature by reflecting near-infrared rays of sunlight efficiently. It is effective for the heat island phenomenon that is a recent hot topic in the news. Surf Cool doesn't include any organic solvents and is environmentally friendly. Easy to use all-in-one water based paint coating –Just open the can and use as is. –No solvent odour, or fear of igniting. –Does not damage the asphalt surface. –Environmental friendly water based paint. Excellent Workability –Application with either a brush or roller makes application simple. –Can also be applied by a sprayer. Excellent Durability –Using degenerated acrylic resin, it adheres well to asphalt and mortar surfaces and excels in water-proof and weather resistance qualities.

28 21-22 September Innovative ideas ts/coating/coating_10.html ts/coating/coating_10.html ZEFFLE Infrared Reflective coating construction is a revolutionary construction method that adds the quality of heat shielding to the durability of fluorocarbons. Just painting on the roofs of factories and warehouses will contribute to energy savings by lowering indoor temperatures and reducing energy costs. Excellent weather resistance is found in fluoropolymer base coatings. Even when exposed to the wind and rain, the paint film maintains its beautiful exterior appearance for many years with no degradation.
