A2PB A2PBEER – Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting A2PBEER OVERVIEW Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting What’s it all about? ECCREDI Council, 9 th November 2017, Brussels 7

A2PB A2PBEER – Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting Background • Buildings are responsible for 40% energy consumption in EU (especially pre 1980) • In Europe public buildings represent 30% of non- residential buildings • Only 1% of existing buildings are retrofitted To achieve 2020 targets and beyond need to retrofit existing buildings ECCREDI Council, 9 th November 2017, Brussels 8

A2PB A2PBEER – Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting The A2PBEER Project Who is involved? Finishing FP7 Framework – February 2018 Many Successful Targets ECCREDI Council, 9 th November 2017, Brussels 9

A2PB A2PBEER – Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting Main Targets: 1. Demonstrate innovative Technological Solutions. 2. Best Practice Retrofit of public buildings in Spain, Sweden and Turkey. 3. Improve their energy performance by 50% 4. Integrate the results and lessons learned into Case Studies and Replicated in Social Housing. 5. Disseminate and exploit results through Training Workshops for building owners and managers, professionals and site managers. ECCREDI Council, 9 th November 2017, Brussels 10

A2PB A2PBEER – Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting Technologies 1. Envelope: External Ventilated Façade Internal Insulated Façade Smart Window 2. Intelligent Fibre Optic Light System 3. Solar Cooling & Heating Collector 4. Smart Dual Thermal Network ECCREDI Council, 9 th November 2017, Brussels 13

A2PB A2PBEER – Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting Design of External Ventilated Façade High performance thermal insulation materials that can achieve high thermal energy resistance, with a low thickness has become a technical challenge PVC clip supporting VIP Cladding (ceramic) Aluminium anchorage VIP panels protected with rubber Thermal pad Aluminium T‐Profile ECCREDI Council, 9 th November 2017, Brussels 14

A2PB A2PBEER – Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting Prototype: FINAL SOLUTION ‐BUCHTAL KeraTwin K20 solution: 1 • VIP Panels : nominal dimension 1100x600mm; thickness (30 mm) + rubber (3+3 mm, only on VIP large faces) + silicone like material 2mm thick to protect VIP edges • PVC clip supporting VIP panels (length as the VIP panel), H profile (central thickness 5mm, lateral thickness 3mm) 2 • Additional continuous vertical PIR‐M insulation (nominal cross‐section 40x36mm) 3 • Supporting structure • L 40/80/150mm aluminium profile, thickness 4mm, with thermal pad • T profiles (2mm) 4 • Cladding – extruded ceramic tiles ECCREDI Council, 9 th November 2017, Brussels 15

A2PB A2PBEER – Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting  Benefits – energy savings, costs, ease of installation, innovation etc.  Excellent thermal properties ‐ thermal conductivity λ=0,005W/mK  The insulation thickness lower in comparison to other systems ‐ 30mm instead of 200mm  The system is easy to install ‐ PVC clip integrating VIP into ventilated facade ECCREDI Council, 9 th November 2017, Brussels 16

A2PB A2PBEER – Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting  Evaluation  VIPs are integrated in the façade system. Carried out detailed thermal bridging assessment of the proposed architectural designs.  Thermal performance  The envelope material in the VIP is air and water‐tight (it is designed and manufactured to retain a vacuum within the VIP). Testing carried out to assess condensation problems, not only surface, but also interstitial condensation.  Condensation performance • The following performances have been verified: • Thermal performance • One‐dimensional U‐value, according to EN ISO 6946[2]. • 2‐3‐dimensional U‐value, when considering multidimensional heat transfer. • Solar heat gain coefficient (g equivalent for opaque envelope) • Condensation performance • Indoor surface condensation & mould growth risk. • Interstitial condensation • Overall mechanical performance of the façade ECCREDI Council, 9 th November 2017, Brussels 17

A2PB A2PBEER – Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting The need for the Technology External insulation systems are not always viable. For historical buildings with facades that are protected from alterations, alternative solutions need to be applied in order to improve thermal performance. An internal insulated facade solution is therefore necessary ECCREDI Council, 9 th November 2017, Brussels 18

A2PB A2PBEER – Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting Internal Insulated Façade The final solution consists of a continuous VIP layer adhered to the existing wall with a free standing standard plasterboard solution on the interior.

A2PB A2PBEER – Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting Considerations. Protection of the VIP from perforation The insulating qualities rely on the vacuum created around the silica core. The VIP must be protected from perforations both during installation and during its building use. HOW? RUBBER PROTECTION ON VIP OSB + LAYER OF MINERAL WOOL Integration of existing services and structures HOW? Provision of service space free of VIPs and vapour barriers with enough depth to incorporate elements Thermal conductivity of VIP = 0.005 W/m.K Thermal conductivity of perforated VIP = 0.023 W/m.K.
