1 Accomplishment and recommendations of standardization Dr Ed Suttie

2 CONTENT 1. Task 2.1: Buildings Code, EPBD analysis and standardization 2. Deliverable 2.1 Assessment of national building codes, EPBD implementation and standards identified Analyse how building codes across Europe take into account energy efficiency, RES and in particular the energy efficiency improvements of envelopes, lighting and HVAC systems of existing buildings 2014 and 2015 issues 3. Deliverable 2.2 Accomplishment and recommendations of standardization Proposals for improving or new regulations and rules Engage in discussions with standards, regulators and expert bodies Presentation at international conferences and expert meetings

3 CONTEXT Trajectory of Energy Savings 2020 a contributing study to Roadmap From 2013 barriers

4 ENGAGING WITH STANDARDS, REGULATORS AND POLICY MAKERS Examples of dissemination activities (conference, workshop, standards meeting and exhibition) required actively presenting knowledge from Ecoshopping project orally, as poster or as an exhibition stand. D8.1 fully details all dissemination activities. In terms of standardization discussion we focus on the commercial and expert events where presentations and meetings with building owners, construction professionals, policy makers, standards delegates (technical experts) and regulators were held. These 49 engagements occurred in Austria, Belgium, Croatia, Germany, Finland, Hungary, Italy, the Netherlands, Romania, Spain and the United Kingdom.

5 Changes during the project lifetime e.g. RES The membership of the European Heat Pump Association has grown which reflects the increase in deployment of heat pumps as key measures of RES in buildings. In 2015 the European Heat Pump Association (EHPA) quality label included Austria, Belgium, Czech Republic, Finland, France, Germany, The Netherlands, Poland, Slovakia, Sweden, Switzerland and the United Kingdom. In 2017 Hungary, Italy, Portugal and Spain are joined and cooperating. This coalescing is reflected across other equipment technologies and the formation of European wide associations accelerates the process and promotes the implementation of European Standard approaches, sharing learning, technology platforms and makes it possible to move forward on wider aspects of national EPBD implementation.

6 CHANGES DURING THE PROJECT LIFETIME E.G. LOW CARBON REFURBISHMENT OF BUILDINGS UK Carbon Trust s guide to achieving carbon savings from refurbishment of non-domestic buildings Ensure that a planned refurbishment delivers carbon savings, in addition to meeting its other objectives Provide clear, practical guidance based on real world experience

7 Changes during the project lifetime e.g. Standards Over 1000 European Standards that connect directly to energy efficiency and the retrofitting of non-domestic buildings. The main Standards Committees in Europe that have generated revisions and the new standards that impact on Energy Performance in Buildings come from CEN/TC Project Committee - Energy Performance of Building project group A further five CEN technical committees have been assigned the task of developing the required standards: CEN/TC 89 - Thermal performance of buildings and building components CEN/TC Ventilation for buildings CEN/TC Light and lighting CEN/TC Heating systems in buildings CEN/TC Building automation, controls and building management ISO family, under the general title Energy Performance of Lifts, Escalators and Moving Walks. Best practice, in the form of CIBSE guide D: Transportation systems in buildings

8 Concerted Action Energy Performance in Buildings

9 NEEDS Whole life costs: An improvement in the deployment of whole life cost approaches to the retrofit solutions and the savings that they accrue in terms of lower energy bills. Harmonised best practice performance criteria Missing best practice specifications for the renewable technologies Best practice guidance for daylighting in non-domestic buildings Building controls are one of the most effective solutions in realising energy savings. EN should be used as the methodology. Lowering carbon impacts: Best practice guidance on low carbon refurbishment of nondomestic buildings structured around a roadmap for the refurbishment process. For the owner there is growing evidence that the market rental value /m2 associated with green buildings can be higher than less-energy efficient buildings. Electricity price varies across Europe and will have an impact on motivation to fit energy efficient technologies. A consistent means of presenting the whole building through life environmental impacts would be of value.

10 SUMMARY A more holistic approach to communicating the benefits and options for energy efficiency implementation is needed. Adoption of energy efficiency measures in buildings at retrofit stage can present significant barriers: Additional costs compared to a cosmetic refresh of a shopping centre which may involve painting and some new highly noticed components e.g. doors Understanding and communication of savings to owner occupier Selecting and specification of appropriate technology solutions for the specific project Knowledge and awareness of energy efficient retrofit technologies and solutions that are available Skills and workmanship of integration of technologies and then successful piloting and snag fixing Skills and knowledge regarding operation and maintenance of energy efficient technologies and equipment The performance gap

11 Better buildings Used better (operational) 1. Landlord-tenant divide 2. Shortage of whole life costing approach at all stages 3. Lack of perceived material value in developing low carbon buildings 4. Lack of ability in supply chain to deliver truly low carbon buildings 7. Lack of motivation due to transaction costs, lack of awareness/information, or lack of transparency in building performance 8. Immateriality of energy costs/savings 5. Non-compliance with Building Regulations 6. Slow refurbishment cycle

12 SUMMARY the Ecoshopping Project has helped to: Integrate knowledge sharing to facility improvement in building control standards Tackle some of the barriers to engaging in an energy efficiency refurbishment or retrofit project Integrate an approach for comparative assessment of building performance Highlighted the need for standardized approach or harmonised guidance on whole life costs, best practice performance criteria, low carbon retrofitting, best practice specification for renewable energy systems Pilot integration of energy performance and building product environmental impact data to provide through life impacts
