Type of Building Code

Type of Building Code

• Cooling Based
• Prescriptive Codes
• Trade Off
• 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
• Model / reference Building
• Mix of different models / Hybrids

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.

• Primary Energy
• Life Cycle Assessment considered (embedded energy)

Energy Uses and Functions Covered by the Code

• Heating

  Heat loads have to be calculated.

• Cooling

  Included in the energy efficiency category calculation according to RakMk D5, when the building has a cooling system.

• Dehumidification

  Necessary air circulation in buildings equipped with ventilation can be controlled, for example temperature, carbon dioxide concentration, or humidity.

• Ventilation

  Calculations required.

• Airtightness

  n50 equal to 2.0 is used for reference building heat loss in Finnish Building Code. For EPC, n50 of 4 is considered unless the measured value is dfferent. Air change rate in new apartments should be at least 0.5 h-1.

• Thermal bridging
• Hot water

  Specific rating DHW dm3.(m2a) and kWh/(m2a) - Depends on the type f building

• Technical installations
• Lighting

  Lighting calculations are required

• Appliances

  Not known at this stage

• Design, position & orientation of building

  Can be included in the overall calculation and achieve credits

• Heat recovery

  Calculations required

• Passive solar
• Passive cooling
• Natural ventilation

  Calculations required

• Solar protection
• Daylighting requirements

  Calculations required

• Renewable Energy (solar, PV, others)
• Local renewable sources
• Energy Offsets/Green Certificates

Enforcement

Type of Enforcement

• Local enforcement
  Municipal building inspection.
• Third party inspection
• Central enforcement
• Accreditation of applicants
  Certificates for new buildings will be provided by the principal designers of the buildings. For existing buildings, the energy certificate may be issued by a qualified expert, energy auditor or property manager. When a qualified expert issues an energy certificate, it is called a "separate energy certificate".
• Post Occupancy control

On-site Inspections Occur

• On-site inspections
• During construction
• Post completion
• Post occupancy
  Not known at this stage.

Certification to Support Enforcement of Code

• Energy Performance Certificate support BC
  For all new buildings, certificates must be presented when applying for a building permit. The certification of new buildings began in early 2008. New buildings constructed in strict accordance with the requirements of the Building Regulations 2012 would typically fall into energy class C. As of January 2009, all existing buildings must be certified when sold or rented.
• Positive labeling for building beyond the minimum BC level
• Existence of EPC register database at national level
• Inspection of boilers
  Partially -voluntary requirements at this stage.
• Inspection of HVAC systems
  Partially -voluntary requirements at this stage.
