Building Regulations 2018 (BR18)

The 2018 version of the Danish building regulations - codes (BR18) update regulations from 2015 (BR15) and specify detailed requirements for building construction under the Building Act. The requirements of the building regulations are primarily designed to ensure building construction achieves minimum standards in fire, safety and health terms. Energy efficiency requirements are also included. Violation of the building regulations can result in a penalty in the form of a fine. These requirements apply to the gross areas of all storeys, incl. basements and useable roof spaces, enclosed balconies etc, external and internal staircases, stairwells, access balconies and lift shafts in each storey. Energy Requirements: Insulation, pipes and tanks optimally placed for sharing heat, ventilation systems meeting requirements for heat recovery in EU Regulation No. 1253/2014 U-Values (W/m2.K) Walls Windows Floor Roof All climate zones 0.3 1.8 0.2 0.2 Windows (kWh/m2/year) Solar energy gains All climate zones 33 Skylights The energy balance for windows and glazed walls must not be less than 17.0 kWh/m2/year The energy balance for skylights and glass windows must not be less than - 0kWh/m2/year. Air Leakage: 1.0 l/s per m2 of heated floor area at a pressure of ) at 50 Pa Space Heating System: Ventilation installations must incorporate heat recovery with a dry temperature efficiency of no less than 73% for all heat recovery systems, with the exception of liquid cooled batteries for which it is 68% (EU Regulation No.1253/2014). Heat pumps for heat recovery must have a minimum coefficient of performance of 3.6 in heating mode. Water Heating System: Domestic water systems supplied by a domestic ventilation heat pump must have a minimum COP (coefficient of performance) at the draw off point of 3.1. Lighting: No requirement Renewable Energy: Solar heating systems must be provided when the expected hot water consumption exceeds 2000l per day and able to meet 95% of demand Requirement to use renewable energy in new buildings and in substantial conversions and alterations, if cost effective. Cost effective measured as (lifetime in years x annual savings in DKK) / Extra investment ‰¥ 1.33 Compliance Software: SBi-Direction 213 Performance Compliance path: Dwellings, student accommodation, hotels, etc.. 30 kWh/m2/year + (1000 kWh/year divided by heated floor area) Offices, schools, institutions, etc.. 41 kWh/m2/year + (1000 kWh/year divided by heated floor area) Administration: Development Authority: Ministry of Transport and Housing/ Danish Transport, Construction and Housing Authority Implementation Authority: Local Authority Verification Authority: Local Authority Enforcement Authority: Local Authority
