REHVA: Country reports from benchmark study on European regulations

  1. 1. Benchmarking Regulations on Energy Efficiency of Buildings Country reports Federation of European Heating, Ventilation and Air-conditioning Associations – REHVA April 30, 2010
  2. 2. Specific country reports France Norway Hungary UK Germany Italy
  3. 3. France Delivered by University of LaRochelle Prof Francis Allard
  4. 4. France RT2005 Principles The French regulation (RT2005) is based on the “3C” rules: • Consumption (including heating, cooling, domestic hot water, lighting and auxiliary equipments) •Cep< Cep ref * • Cep< Cep max** • Comfort (Summer comfort) (Tic < Tic ref) *** • Characteristic minimum values (target values for every components and energy systems linked to the building) • A Ubat (overall heat loss coefficient of the building) has also to be checked. • It is mandatory to all new buildings after 1st of September 2006 * The project should be compared to a reference building which is a theoretical building ,a twin building of the real one with the same geometry but using reference components and systems defined by the regulation. ** In any case a maximum value Cepmax is defined for each climatic zone. *** For every building without air conditionning, a maximum value of indoor temperature has to be checked in summer.
  5. 5. France: Cep max and Climatic zones Heating energy source Climatic Zone Cep max kWh/m2 year Fossil fuels H1 130 H2 110 H3 80 Electrical heating H1 250 H2 190 H3 130 Cep = 2.58 x C electricity + C other energies For residential buildings, Cep max does not include lighting and auxiliary equipments
  6. 6. France: Target values Component U max (W/m2K External Wall 0,45 Wall in contact with a non heated room 0,45 Floor on external space 0,36 Floor on crawl space 0,40 Roofs 0,28 Metalic roofs 0,34 Windows, external doors 2,60 Double façades 2,60 The thermal bridges are also limited by target values
  7. 7. France: Air permeability Q in m3/(hm2) for 4Pa Target value Default value Individual houses 0,8 1,3 Residential (multifamily) buildings 1,2 1,7 Others 2,5 3,0
  8. 8. France: Existing buildings Extension of RT2005 to existing buildings (2007) • mandatory for all building built after 01/01/1948 with more than 1000 m2 when the rehabilitation cost exceeds 25% of the market value of the building. • same methodology as RT2005: refprojet CepCep ≤ maxCepCepprojet ≤ initialprojet CepCep 7,0≤ non residential buildings Or use of technical reference solutions (for individual houses only) Either
  9. 9. France: Energy certificates • Mandatory for building sales from 1/11/2006 • Mandatory for building rents from 1/07/2007 • Established directly for new buildings within the regulatory control • Public display for existing public buildings with more than 1000 m2 since 2/01/2008. • Can be establish by • conventional calculation (with certified calculation tools) • energy bills of the last 3 years.
  10. 10. Presentation in 4 standard pages - Description of the buildings and main equipments - Evaluation of consumption in primary energy (heating cooling and domestic hot water (lighting in non residential) - Corresponding costs - Energy label +CO2 emissions - Recommandations and improvement solutions have to be defined France: Energy certificate
  11. 11. France: Main features Main features of the French approach to EPBD implementation are: • The regulation limits the total energy demand in terms of overall primary energy • The regulations limits the overall heat losses of the building (Ubat) • The regulation put a penalty on air permeability if it is not defined clearly • For individual houses technical solutions can be used directly without calculation • The calculation procedure is made using the same core programme given by CSTB. (simplified dynamic calculation with conventional climatic data). • A control based on random selection of buildings can be made • Energy certificate established by registered bodies
  12. 12. France: Accompanying Labels Buildings with specific performance can be awarded by a specific certificate called “label” • HPE labels (High Energy Performance 27/07/2006) • H.P.E : Cref - 10%, • T.H.P.E : Cref - 20%. • Renewable Energy Labels(HPE enr and THPE enr same condition as HPE but demonstrating the use of renewable energies) • BBC (Low Energy Building) • Cep < 50 KWh/m2 year with modulation following the climatic zones
  13. 13. France: Trends for a new regulation • A new regulation is planned to be set in 2012. • The technical groups are already working and the main elements would be: • Global extension of the regulation to new or retrofitted buildings without surface area conditions, • More restrictive target values: • Cep ref < 50 KWh/m2 year for new buildings • Cep ref < 80 KWh/m2 year for existing buildings • More restrictive conditions for air permeability, • More care for thermal bridges, • More care should be taken about summer comfort conditions • More stress about the integration of renewable energies.

Also the ventilation rate and indoor temperature set-point should comply with minimum values.
  17. 17. Norway: Main features Main features of the Norwegian approach to EPBD implementation are: • Strict minimum requirements for U-values & airtightness, near cost-optimal • The regulations limit net energy demand, thus ignoring the efficiency of energy delivery systems (e.g. boiler efficiency), and • The EP calculation standard is flexible (any software that is verified) and fixes input data related to occupant behaviour, including all heat gains (equipment, people, default lighting), hot water use, operating hours, set-point temperatures for heating & cooling, and minimum ventilation rates. • Self-assessment of energy labels is allowed. Qualifications are only needed for non-residential buildings (There will be penalties for misuse) • Inspection includes all ventilation systems (>12 kW), not only A/C systems
  18. 18. Norway: Main features The combined effect of these features has the following benefits: • It ensures robust building envelopes (long-term and uniform quality of all envelopes), more so than many other European countries • Virtually all buildings need balanced ventilation & heat recovery to comply. The regulations distinguish between air-to-air heat exchangers and air-to-air heat pumps in ventilation units, as the latter doesn’t reduce net energy demand. • Heat pumps and efficient energy systems are given due credit in the energy label (delivered energy). Renewable systems and heat pumps are regulated by minimum requirement of >40% RES, and promoted with a secondary energy label based on %RES. • Unbureaucratic energy labelling, no immediate bottleneck due to shortage of certified assessors • A building’s energy label is calculated fairly, assuming fixed ‘typical’ user behaviour and internal heat gains.

  23. 23. Hungary: Main features Main features of the Hungarian approach to EPBD implementation are: • The requirements are in force since 1st of September, 2006. • The requirements have three different levels: building elements, building as a whole, building and service system together. • The requirements of building elements does not garantee the compliance with the requirements of the building as a whole. • The fulfilment of the specific heat load requirement does not garantee the requrements regarding the building and the services system together will be fulfilled. • The requirements of primary energy needs are given as function of surface to volume ration for 3 building categories. • The requirment mainly are not specified in details, the main goal to fulfil the three levels of requirements.
  24. 24. Hungary: Main features Main features of the Hungarian approach to EPBD implementation are: • The Ministerial Degree 7/2006 includes the requirement that for buildings over 1000 m2 floor area the feasibility of use of renewable energy must be checked. • The EP calculation sofware is given (commercial). • The mandatory certification of existing buildings will be start in 2011. • The qualification requirements have been determined by the Chamber of Engineers. Certification may be issued by licenced experts after having passed the exam (with min BSc degree). • The mandatory inspection of heating and air-conditioning systems will be start in 2011.
  25. 25. UK Based on material and interview by Mr Derrick Braham
  26. 26. UK • UK has been very active in improving the energy efficiency of buildings and the government regulations have been tighten in short intervals. 2002 – 2006 - 2010 • The plans is to revise and tighten the regulations in 2013 – 2016 – 2018 - 2020
  27. 27. UK 2010 regulations • The 2010 revision to the UK regulations are due to be published in the next month or two, for implementation on the 1st October 2010. They are expected to require a further 25% CO2 reduction in the buildings total emission simulation. • To make things even more interesting in the immediate future for both Architects and their HEVAC consultants, the 2010 regulations will also specify that a further 25% CO2 reduction that will be required in the 2013 Regulation revision.
  28. 28. CO2 emissions as criteria • UK is the only EU country that uses as regulatory basis the CO2 emissions – see table below in the notes section • Limits for CO2-emissions kg/m2 are given by building type and used also as basis of energy performance certificate • However, there is pressure towards primary energy criteria also in UK
  29. 29. CO2 emissions in UK 1. Fuel 2. CO2 emission kgCO2/kWh 3. Natural gas 4. 0,194 5. LPG 6. 0,234 7. Biogas 8. 0,025 9. Oil 10. 0,265 11. Coal 12. 0,291 13. Anthracite 14. 0,317 15.

Grid displaced energy (generated in the building) 24. 0,568 deducted form the total building emissions 25. Waste heat (including industrial processes) 26. 0,0188
  30. 30. Display Energy Certificates in UK (DECs) • DECs show the measured energy use of a building (fuel and electricity). • DECs were introduced in 2008 as part of the EPBD and dsiplayed in public buildings. • Plan is to extend DECs in 2010 to all commercial buildings, and in 2013 to all non-domestic buildings, data in DECs to be revised annually. • DEC includes also recommendation for the improvements. These recommendations shall be revised every 7 year. • A data base of DECs is collected and summaries made publicly available. • The quality of DECs is controlled by government with a statistically significant sample (app 5 %). • Experience from DECs is extremely good. They also show wide differences between calculated certificates (EPCs) and measured energy use values in DECs.
  31. 31. Carbon reduction commitments in UK • CRC is an EU initiative from 2008. It has been now successfully applied in the UK in the entities in which the energy bill in more than 500 000 pounds per year. • The principle of the applications is the follows: • All similar type (including use) of buildings/factories and other energy users are first categorized. • Then they are ranked by the use of the energy. Then a medium user is defined. • All those using more than medium user have to pay penalty, and all those using less than medium user get subsidy. • The total net cost is zero.
  32. 32. Germany
  33. 33. Germany – development of regulations
  34. 34. Germany -sanctions and penalties (1) The German energy decree defines in § 27 the following regulatory offenses: • missing inspections or inspections carried out by unauthorised personnel • installation of boilers without CE label • lacking insulation of heating pipes • inappropriate control system for heating system • incomplete, incorrect or delayed energy performance certificate • issuing of EP certificates by unauthorized personnel • incorrect or lacking confirmation by construction companies regarding the compliance with EP requirements for major renovations and renewed building components or systems
  35. 35. Germany -sanctions and penalties (2) The corresponding penalties are defined in the Energy Saving Act of 2009 (Energieeinsparungsgesetz – EnEG) [11]. Here, penalties between € 5,000 and € 50,000 are defined for: • regulatory offences against the thermal protection and energy efficiency of building systems requirements (EP requirements) and regulatory offences against the inspection of building systems and the installation of heating control systems: 50,000 € • regulatory offences against the issuing of EP certificates (missing, delayed, incorrect or issued by unauthorised personnel): 15,000 € • regulatory offences against the compliance check procedure
  36. 36. Germany -sanctions and penalties (3) There are also regulatory offences against the Renewable Energies Heat Act as defined in § 17 of the act. Here the offences are divided into: • not covering or not correctly covering the generated energy by renewable energy (as required); • not providing (not correctly or in time providing) the proof for covering the generated energy by renewable energy; • presenting an incorrect ratio of the covered generated energy by renewable energy; • not keeping the proof for at least 5 years.
