Finland

Summary

The D3 is a performance-based code that requires a mandatory energy frame calculation to establish the expected monthly final energy consumption (E-luku energy weighted factor) of residential and non-residential buildings. The allowable final energy frame is set to kWh/m2/pa and depends on the type of building. The code addresses thermal envelope requirements and energy using in the calculation, including, HVAC, hot water, lighting, heat recovery and bio-climatic design.

Finland has had prescriptive energy efficiency requirements for buildings since the 1990’s. The first performance-based code is the latest 2012 code installment. The code and supporting policies encompasses dynamic aspects including, very low maximum u-values established relevant to climate, air-tightness testing, well-established EPC programs and incentive schemes, special efficiency requirements for public buildings and the implementation Passive House standards by 2015 for residential buildings.

  • 4 climate zones: 1 - Cool, Dry, Marine, 2 - Cold,Dry, 3 - Very Cold, 4 - Subarctic.

Type of Building Code

Type of Building Code:

  • Model code, frame or actual code:
    National Code
  • Performance Codes for Refurbishments:
    Partially.
  • Performance Codes for New Builds:
    The D3 is a performance-based code that requires a mandatory energy frame calculation to establish the expected monthly final energy consumption (E-luku energy weighted factor) of residential and non-residential buildings.
  • Energy Declaration

Energy Covered

Basis for Energy Requirements:

  • Overall performance frame:
    The calculation methodology is described in the building regulations. It must be used for calculating energy consumption when issuing energy certificates for small residential buildings. When applying for a building permit or issuing energy certificates for other building types (new buildings), EN standards, other more detailed calculation methods and simulation tools can also be used.
  • Final Energy:
    E-luku energy-weighted factor - The energy label for new buildings is always based on calculated final energy consumption. The scale in the energy certificate is an absolute value (kWh/m2.year). There are ten different scales for ten different building types - Energy Report required. Annual energy consumption must be calculated using monthly calculation.

Energy Uses and Functions Covered by the Code:

  • Heating
  • Cooling
  • Dehumidification
  • Ventilation
  • Airtightness
  • Thermal bridging
  • Hot water
  • Building parts (lifts, pumps etc)
  • Technical installations
  • Lighting
  • Design, position & orientation of building
  • Heat recovery
  • Passive solar
  • Passive cooling
  • Natural ventilation
  • Solar protection
  • Daylighting requirements
