Transcription

1 Low Energy, Low Carbon Buildings: Current and emerging developments for buildings other than dwellings CIBSE CPD Series 8 February 2012 Martin Vaughan Assistant Principal, Architecture /Building Standards, Dept. of the Environment, Community and Local Government

2 Overview 1. Energy rating in Ireland: experience to date for buildings other than dwellings. 2. Recast Energy Performance of Buildings Directive (EPBD) 3. Building Regs. Part L - Non Domestic 4. Making it Happen 5. Future Focus / Key Challenges

3 Status December 2011 Non Domestic 8019 BERs on public register 247 BER Assessors Display Energy Certificate (DEC) 306 Valid DECS to date 179 Registered DEC Assessors

7 Recast Energy Performance of Buildings Directive Directive must be transposed by July 2012; New requirements begin from 9 Jan 2013 at earliest Robust BER system in place under original EPBD: 280,000 valid BERs currently in place for Dwellings 8,000 valid BERs currently in place for non-domestic buildings Transposition Plan and new SI being finalised for consultation by end 2011

8 Recast Energy Performance of Buildings Directive Key Additional Requirements Art 5 Cost Optimal Regulation Consultancy to identify cost optimal standards early in 2012 Report to EU Commission by 30 July 2012 Art 7 Energy Refurbishment of Buildings subject to 25% of surface area undergoing works TGD L currently addresses existing buildings; future Part L amendments will reflect new terminology Art 12 Mandatory reference to BERs in advertising from 9 Jan 2013 Enabling provision in new SI; practical guidelines to be published by SEAI

9 Recast Energy Performance of Buildings Directive Key Additional Requirements (Continued) Art 13 Requirement to display energy certificates extended to decreasing Floor areas and increasing scope of Buildings: Buildings Occupied by Public authorities and frequently visited by public 1000 m2 (current) 500 m2 from 9 Jan m2 from 9 Jan 2015 Non-domestic buildings frequently visited by the public and over 500m2 from 9 Jan 2013 Existing approach to DECs for public buildings currently being reviewed before deciding on new approach; proposals will be included in public consultation. Art 9 Nearly Zero Energy Buildings i.e. Buildings with a high energy performance where the very low amount of energy required should be to a very significant extent be met from renewable sources including onsite or nearby Outline plan for Ireland s transition to nearly zero energy buildings will be included in Recast EPBD Transposition Plan

10 Planning & Development Alternative Energy Systems feasibility study mandatory for new buildings and encouraged for existing buildings Exemptions for small scale renewable technologies for residential dwellings, industrial buildings, business premises and agricultural holdings Sustainable Residential Developments in Urban Areas-Guidelines for Planning Authorities -provides for energy efficient design, orientation and district renewables where appropriate

11 Buildings Other than Dwellings: Indicative Roadmap What s next? Timeline Part L 1 % Improvement Baseline 40% 60% Nearly Zero Energy Framework 1 Energy and CO2 Performance is calculated using Non domestic Energy Assessment Performance (NEAP) Software to EN 13790

12 Buildings Other than Dwellings Full review of Part L /TGDL in 2012/2013 Broad approach of review to make the requirement contained in the Regulations more specific to tighten the performance levels specified in TGD L to recognise that a range of factors contribute to the overall energy consumption of buildings and to retain flexibility and options for designers/specifiers/owners

13 Buildings Other than Dwellings RFT for consultancy now being finalised: Scope: To identify ambitious & realisable energy/co2 performance targets for next and future revision of Part L make the maximum practicable contribution to Government energy/co2 targets, be comparable with the best in Europe;

14 Buildings Other than Dwellings Consultancy Tasks Analysis of Current Regulations and policy and comparison to other MS Identification of typical buildings and a design and analysis of packages of measures to be modelled. Modelling of these packages of measures to achieve step improvements in energy performance of buildings. (N.B. Feasibility and Cost/benefit) Recommendations on targets, improvement of NEAP parameters and proposed revisions to TGD L.

15 Buildings Other than Dwellings Timeframe for Review Consultants appointed in Q2 Consultants report by end Q4 BRAB recommendations to Minister early 2013 Public consultation/eu notification - 3 months Revised Part L/TGDL before end 2013

16 Making It Happen Publications on selecting, installing, commissioning & maintaining systems for dwellings but useful guide to other buildings particularly small non-complex buildings, e.g. DECLG/SEAI/Homebond s Limiting Thermal Bridging and Air Infiltration Acceptable Construction Details DECLG/SEAI s Heating and Domestic Hot Water Systems for dwellings Achieving compliance with Part L Technical Guidance Document F Ventilation DECLG/SEAI s Installation and Commissioning of Ventilation Systems for Dwellings-Achieving Compliance with Part F (currently open for consultation) NSAI s draft SR 50-2:2010 Code of practice for building services - Part 1: Domestic plumbing and heating (To be published 2012) NSAI s draft SR 50-2:2010 Code of practice for building services - Part 2: Solar panels (to be published 2011) SEAI Harp Database

17 Making It Happen Installer / Certifier schemes, e.g. Part D certification Agrement or equivalent approved systems Agrement approved installer schemes for; Cavity Wall Insulation External Wall Insulation NSAI s Window Energy Performance Scheme NSAI s Air tightness testers Scheme NSAI s Thermal Modellers Scheme (imminent)

18 Making It Happen Building Control reforms Mandatory certification by designers/builders on commencement Mandatory certification by responsible person on completion Lodgement of drawings Regionalisation of Building Control function Development and Support of Building Control Authorities

19 Challenges/Opportunities Challenge Maintaining momentum in current economic environment Advancing Standards/Regulations for Buildings Other Than Dwellings and inclusion of Cost Optimal methodology Ensuring robustness and reliability of new renewable technologies and retrofit approaches Ensuring construction standards meets design specification for low energy buildings Improving occupier interaction in using and operating low energy buildings Increasing scope of and compliance with requirement to display energy certification Action Recast EPBD, Programme for Gov. & national competitiveness provide drivers for change Immediate priority-development of regulations to progress Development of product certification schemes, installer training schemes, national standards and codes of practice Robust commissioning procedures, upskilling workforce, simple designs, product certification and verification. Handover/User manuals, simple controls, smart meters Awareness; Integration with energy mgmt plans.
