The latest BBR sets mandatory overall performance demands for dwellings and non-residential buildings that depends on the location and type of heating system employed. The code outlines prescriptive requirements for the thermal envelope and encourages efficient and thoughtful design of the energy consuming systems including, HVAC, hot water, lighting, auxiliary systems, as well as materials and products. Compliance is achieved through measuring the actual energy use of the (occupied) completed building and showing it to be less than or equal to the allowable energy frame.

Sweden has a long history of energy efficiency requirements for buildings, with the first prescriptive requirements being implemented in 1946. The first performance-based code arose following the EPBD in 2002. The latest BBR encompasses many dynamic aspects including low overall u-values requirements, mandatory energy measurement, Specific Fan Power requirements, performance requirements for buildings undergoing renovation and interim (2015) performance targets for most building types in preparation for the nZEB target of 2020.

Geographical Coverage

Sweden

Code set at:

National Level

Coverage of Building Code:

• Residential buildings
  • One family
  • Multiple family buildings
• Commercial buildings
  • Offices
  • Retail and wholesale
  • Hotels
  • Hospitals
  • Educational buildings
• Public buildings
  • Offices
  • Hospitals
  • Educational buildings

GBPN Climate Classification:

• Heating Based
• 3 climate zones, North - Very Cold/subarctic, Middle - Cold, and South - Cold marine, Cold. All are heating based.
  

Type of Building Code:

• Model code, frame or actual code:
  National Code.
• Performance Codes for Refurbishments:
  Performance based requirements based on calculated final energy and post occupancy energy measurement.
• Performance Codes for New Builds:
  Performance based requirements based on calculated final energy and post occupancy energy measurement.
• Energy Declaration:
  The two first categories of buildings must always have an energy declaration of less than ten years old, and after the recast of EPBD all buildings bigger than 500 sqr meters which the public can attend must declare energy use.

Basis for Energy Requirements:

• Overall performance frame:
  Most buildings are required to meet an overall performance frame and It shall be possible to continuously monitor the building’s energy use by a method of measurement. The method shall ensure that the energy use of the building can be read to enable calculation of the building’s energy use for the desired time period.
• Final Energy:
  The performance of final energy [kWh/m2 Atemp] is calculated using the measured values from heating and cooling energy, as well as energy used for the ventilation system, domestic hot water and for the property’s energy, including for example pumps and lighting in public spaces; all this is divided by the area [Atemp] of the building that is intended to be heated to over 10 °C.

Energy Uses and Functions Covered by the Code:

• Heating
• Cooling
• 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
• Renewable Energy (solar, PV, others):
  The building's specific energy use may be reduced by solar energy, No requirement in building regulations, but there are requirements in relation to electricity supply mix by RE certificates.

Enforcement Status of Code:

Mandatory

Type of Enforcement:

• Local enforcement
• Third party inspection
• Post Occupancy control

On-site Inspections Occur

Incentives/Rewards to Encourage People to go beyond Minimum Level?

Incentives and subsidies are administrated by Boverket and the statistics are published on the website www.boverket.se. and Energy Demonstrations by http://energimyndigheten.se/en/

Involvement of Stakeholders in the Development of Codes

During all work with revisions of the building code the stakeholders get a period in the middle to express their opinions.

Level of Training Provided to Stakeholders Following Implementation of Code?

The national board goes out to the municipalities and educates the public personnell and the education companies then they havet o educate the local stakeholders.
