Type of Building Code

Type of Building Code

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

  Lithuania’s mandatory Technical Regulation of Construction is a performance-based code that requires an energy frame (reference building) calculation to establish the maximum allowable energy consumption of new residential and non-residential buildings.

• Energy Declaration
• Model / reference Building

  The energy performance efficiency of each building is evaluated solely using the reference building method, that is, a comparison between the normative, the reference and the calculated energy consumption value for each building.

• Mix of different models / Hybrids

Energy Covered

Basis for Energy Requirements

• Overall performance frame

  Maximum energy demand - The calculation method does not set any requirements for primary energy consumption values in buildings. The energy performance efficiency of each building is evaluated solely using the reference building method, that is, a comparison between the normative, the reference and the calculated energy consumption value for each building. The certification of buildings in Lithuania is based on calculations and building audits, but not on the measurement of energy consumption.

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

Energy Uses and Functions Covered by the Code

• Heating

  Values of various normative (N.h.s.) and reference (Rh.s.) efficiency coefficients of heating systems.

• Cooling
• Dehumidification
• Ventilation

  Specific efficiency co-efficients required for the mechanical ventilation systems with or without heat recovery. Ventilation related energy consumption is assessed only during the period of the year in which heating is used.

• Airtightness

  For naturally ventilated building, maximum n50=3 h-1, for mechanically ventilated buildings, maximum n50=1.5 h-1.

• Thermal bridging

  Linear value - 'ΨN 0.18

• Hot water

  Specific efficiency co-efficient required of hot water preparation systems and control devices, which depend on the type of system and fuel used. Energy consumption for domestic hot water and electricity is determined according to the default values, without taking the usage of individual tenants into account. Energy consumption during the summer is only assessed for domestic hot water and electricity use.

• Technical installations
• Lighting

  Included in the calculation

• Appliances

  Not known at this stage.

• Design, position & orientation of building

  Can be included in the calculation.

• Heat recovery

  Considerd within mechanical ventilation.

• Passive cooling

  Can be included in the calculation.

• Natural ventilation

  Useful area of a building with a natural ventilation system in steps of 0.01 m2must be included in the information presented for the certificate

• Solar protection

  Solar thermal gains calculated in performance calculation.

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

Enforcement

Type of Enforcement

• Local enforcement
• Third party inspection
• Central enforcement
• Accreditation of applicants
• Post Occupancy control

On-site Inspections Occur

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

Certification to Support Enforcement of Code

• Energy Performance Certificate support BC
  Mandatory for new buildings and when existing buildings are rented or sold, The certificates of energy performance of buildings can only be issued by the certified qualified experts of energy performance of buildings. The experts must conform to the requirements set in the rules, pass a training course and an exam, and obtain a certificate of qualification.
• Positive labeling for building beyond the minimum BC level
• Existence of EPC register database at national level
  Available at the Certification Center of Building Products (SPSC - Statybosprodukcijosserti␣kavimocentras).
• Inspection of boilers
  A regular inspection of boilers, working on non-renewable solid and liquid fuels, should be done every 2 or 3 years, depending on the boiler’s installed capacity. Heating installations with boilers with a capacity exceeding 20 kW and older than 15 years should undergo a one-off inspection of the whole heating installation - Inspectors are Energy Companies.
• Inspection of HVAC systems
  Air-conditioning systems with a capacity of more than 12 kW should be inspected every 3 years - Inspectors are Energy Companies.
