Type of Building Code

Type of Building Code

• Cooling Based
• Prescriptive Codes
• Trade Off
• Performance Codes for Refurbishments
• Performance Codes for New Builds

  The EnEV is a performance-based code that requires a mandatory (equivalent model building) energy frame calculation to establish the expected primary energy consumption of residential and non-residential buildings.

• Energy Declaration
• Model / reference Building

  The energy performance requirement is based on an equivalent model building and measured as kWh/m2/year of primary energy.

• Mix of different models / Hybrids

Energy Covered

Basis for Energy Requirements

• Overall performance frame
• Final Energy
• Primary Energy

  The energy performance requirement is based on an equivalent model building and measured as kWh/m2/year of primary energy.

• Life Cycle Assessment considered (embedded energy)

Energy Uses and Functions Covered by the Code

• Heating
• Cooling
• Dehumidification
• Ventilation
• Airtightness

  For naturally ventilated buildings, n50 is 3.0h-1 and for mechanically ventilated buildings, n50 is 1.5h-1.

• Thermal bridging
• Hot water
• Technical installations
• Lighting

  For non-residential only, maintenance factor 0.6WF-0.8WF

• Appliances
• Design, position & orientation of building
• Heat recovery
• Passive solar
• Passive cooling

  Partially.

• Natural ventilation
• Solar protection
• Daylighting requirements
• Renewable Energy (solar, PV, others)

  Requirement of heat supply based on renewable energy 15 ~ 50% depending on the type of renewable energy and building.

• Local renewable sources
• Energy Offsets/Green Certificates

Enforcement

Type of Enforcement

• Local enforcement
  Not known at this stage.
• Third party inspection
  Not known at this stage.
• Central enforcement
• Accreditation of applicants
• Post Occupancy control
  Not known at this stage.

On-site Inspections Occur

• On-site inspections
• During construction
• Post completion
• Post occupancy

Certification to Support Enforcement of Code

• Energy Performance Certificate support BC
  EPC had been required since 2002 now use the Calculation Method since 2008.
• Positive labeling for building beyond the minimum BC level
• Existence of EPC register database at national level
• Inspection of boilers
  Regular inspection of boilers has been mandatory for many years, and in fact to a much greater extent and at shorter intervals than those provided for in the EPBD.
• Inspection of HVAC systems
  Every air conditioning unit with a thermal output of more than 12 kW also has to undergo an inspection by a specialist engineer every 10 years.

Penalties for Non-compliance

• None

• Imprisonment
  Not known at this stage.
• Refusal of permission to occupy
• Refusal of permission to construct
• Demolition
  Not known at this stage.

Measures Supporting Enforcement

Code History and Future Targets

• How far in advance are future targets set?

  2018, 2020
• Are stakeholders informed of future targets far in advance?

  Yes

Zero Energy Targets

• Are all end uses considered in the target?
• Is there a realistic roadmap towards ZEB
• National Target date for nZEB

  By 2020 buildings should be operating without fossil fuel. The German government has committed to reducing the primary energy demand of buildings by 80% by 2050. Achieving this reduction will require foremost efficiency improvements, with a first milestone of a 20% reduction in heat demand levels by 2020.

• Special Requirements for public buildings
