Type of Building Code

Type of Building Code

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

  The OIB is a performance-based code that requires a mandatory energy frame calculation to establish the expected primary energy consumption of residential and non-residential existing buildings undergoing renovation (25-38% higher than new builds).

• Performance Codes for New Builds

  The OIB is a performance-based code that requires a mandatory energy frame calculation to establish the expected primary energy consumption of residential and non-residential building as well as existing buildings undergoing renovation (25-38% higher than new builds).

• Energy Declaration
• Model / reference Building
• Mix of different models / Hybrids

Energy Covered

Basis for Energy Requirements

• Overall performance frame
• Final Energy
• Primary Energy
• Life Cycle Assessment considered (embedded energy)

Energy Uses and Functions Covered by the Code

• Heating

  All building types - maximum of 54.4 [kWh / m2a] heating demand for residential buildings and maximum of 18.7 [kWh / m³ a] heating demand for non-residential buildings

• Cooling

  Non-residential only

• Dehumidification
• Ventilation
• Airtightness

  n50 is 3.0 & n50 is 1.5

• Thermal bridging

  Designs should be planned and constructed so that thermal bridges be minimized. In the case of two-dimensional thermal bridges must be maintained in new construction and major renovation of the ÖNORM B 8110-2.

• Hot water

  Included in overall calculation.

• Technical installations
• Lighting

  Included in overall calculation.

• Appliances
• Design, position & orientation of building

  Included in overall calculation.

• Heat recovery

  Included in overall calculation.

• Passive solar

  Included in overall calculation.

• Passive cooling
• Natural ventilation

  Included in calculation

• Solar protection
• Daylighting requirements

  Included in calculation

• Renewable Energy (solar, PV, others)

  When constructing new buildings with a net floor area of more than 1000 m2, alternative systems are used, unless this is technically, environmentally and economically efficient. Alternative systems are a) energy supply systems based on renewable energy sources, b) combined heat and power plants, c) district and refrigeration, d) heat pumps and e) fuel cells.

• Local renewable sources
• Energy Offsets/Green Certificates

Enforcement

Type of Enforcement

• Local enforcement
• Third party inspection
• 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
  Not known at this stage.

Certification to Support Enforcement of Code

• Energy Performance Certificate support BC
• Positive labeling for building beyond the minimum BC level
• Existence of EPC register database at national level
  Data held individually by each region up until 2011. Centralised system had been introduced recently
• Inspection of boilers
  The mandatory inspection report includes little information, comprehensive inspection reports will be introduced in the 2012 EPBD recast.
• Inspection of HVAC systems
  The inspection of air-conditioning (A/C) systems is still at an early stage.

Penalties for Non-compliance

• None
  Not known at this stage
• Fine
  Not known at this stage
• Imprisonment
  Not known at this stage
• Refusal of permission to occupy
• Refusal of permission to construct
• Demolition

Measures Supporting Enforcement

• Commissioning requirements
  Boilers and HVAC systems are required to be commissioned.
• Airtightness testing required prior to compliance
• Mandatory Computer Modeling
• Training of Inspectors
  Qualified experts are not obliged to attend recognized courses, but these are offered (see also chapter 2 “quality assurance” for experts issuing EPCs) and also used to a large extent: at least 1,500 experts already profit from the knowledge and the experience of others.

Values for New Buildings

Code History and Future Targets

• Are stakeholders informed of future targets far in advance?

  Yes

Zero Energy Targets

• Definition of nZEB/ZEB/Plus Energy etc
• Are all end uses considered in the target?
• Is there a realistic roadmap towards ZEB
• National Target date for nZEB

  2018 public buildings, 2020 all other buildings.

• Special Requirements for public buildings

Supporting Measures

• Supporting Certification Schemes
• Codes Free to Access?
