/

02.01

Are building codes set as overall value, primary energy, environment (CO₂), reference building or other

The main indicator is the primary energy consumption; a CO₂ indicator must also be present (without requirement level) and the requirement in non-residential buildings is a function of a reference building primary energy consumption.

02.02

Requirements for energy performance of residential buildings in current building code

45 + max(0; 30-7.5 * C) +15*max(0; 192/VEPR-1) kWh/m².year

C= compactness
V= volume of the building-unit

02.03

Requirements for energy performance of non-residential commercial buildings in current building code

Cf table 2

At this point in time, with non-residential units we refer to offices and schools only.

C= compactness

The ‘X’ is a reference net heating requirement that has been designed for EPB-units whose poor orientation or compactness makes it unfeasible to enforce compliance with a net heating energy requirement of 15kWh/m².year

02.04

Requirements for energy performance of non-residential public buildings in current building code

Cf table 2

No specific requirement for public buildings, as every building must be NZEB

02.05

Is the performance level of nearly zero energy (NZEB) for new buildings defined in national legislation?

Yes

02.06

Nearly zero energy (NZEB) level for residential buildings (level for building code)

45 + max(0; 30-7.5 * C) +15*max(0; 192/VEPR-1) kWh/m².year

C= compactness
V= volume of the building-unit

02.07

Year / date for nearly zero energy (NZEB) as level for residential buildings (as indicated in 02.04)

2015 (Residential only)

02.08

Nearly zero energy (NZEB) level for all non-residential buildings (level for building code)

Cf table 2

02.09

Year / date for nearly zero energy (NZEB) as level for non-residential buildings (as indicated in 02.06)

2019 (offices and teaching buildings)

2021 (All other building uses)

02.10

Are nearly zero energy buildings (NZEB) defined using a carbon or environment indicator?

No, only Primary Energy Requirement in kWh/m².year

02.11

Is renewable energy a part of the overall or an additional requirement?

Is part of the overall requirement

02.12

If renewable energy is an additional requirement to NZEB, please indicate level

02.13

Specific comfort criteria for new buildings, provide specific parameters for instance for airtightness, minimum ventilation rates

Ventilation rate requirements: YES

• Residential (Annex XIX)
• Non-Residential (Annex XX)

Overheating: Yes, for residential units

In case of overheating, the temperature shall not exceed 25°C for more than 5% of the year

Defined in the execution order of 2007/12/21 fixing the requirements in matter of energy performance and indoor climate of buildings

03.01

Is the level of nearly zero energy (NZEB) for existing buildings set in national legislation?

No

03.02

Is the level of nearly zero energy (NZEB) for existing buildings similar to the level for new buildings?

Above a certain level, major renovation NZEB requirements are the 'same as for new buildings'. Other existing buildings should reach the target defined in the long-term renovation strategy.

03.03

Definition of nearly zero energy (NZEB) for existing residential buildings (if different from new buildings)

Same as new buildings with the PEC_max level requirement multiplied by 1.2

03.04

Definition of nearly zero energy (NZEB) for existing non-residential buildings (if different from new buildings)

Same as new buildings with the PEC_max level requirement multiplied by 1.2

03.05

Overall minimum requirements in case of major-renovation

For renovations with a less than 75% change in the envelope and replacement of all technical installations:

U-value requirement (Annex XIV): (Table 3)

Ventilation rate:

• Residential (Annex XIX)
• Non-residential (Annex XX)

Definition for units considered as new:

A greater than 75% change in the envelope and replacement of all technical installations

Requirements:

U-value requirement (Annex XIV) (Table 3)

Ventilation rate (Annexes XIX & XX)

Net Heating Requirement (for residential buildings only): 1.2 * max (15; X) kWh/m².year

Primary Energy Requirement (for residential and non-residential buildings): Same as new buildings with the PEC_max level requirement multiplied by 1.2

03.06

Minimum requirements for individual building parts in case of renovation

U-value requirement (Annex XIV): (Table 3)

Ventilation rate:

• Residential (Annex XIX)
• Non-residential (Annex XX)

Annexes of the execution order of 2007/12/21 fixing the requirements concerning energy performance and indoor climate of buildings

03.07

National targets for renovation in connection to Long Term Renovation Strategy (number or percentage of buildings)

All residential units will have to meet a PEC_max requirement of 100 kWh/(m².y) on average.

03.08

National targets for renovation in connection to Long Term Renovation Strategy (expected reductions and relevant years)

The target has to be reached by 2050 but the renovation will be planned from 2025 until 2050 in order to achieve this goal. In compliance with the EPC, renovation works must happen for each dwelling/unit every five (5) years from 2025 until the target is met.

04.01

Number of energy performance certificates per year (for instance average or values for of 3-5 years)

3,206 EPC/year for new building units

92 EPC/year for existing non-residential buildings

25,000 EPC’s/year for existing houses and apartments

Average (2016-2019)

04.02

180,070 of units with an EPC

Residential unit:

• New:            18,055
• Existing:       244,600

04.06

Additional training demands for assessors

Five (5) days + retraining sessions when requested by the authority.

Mandatory refresher training of five (5) days for EPB certificators (for existing residential buildings)

04.07

05.01

Is there a national definition of smart buildings?

No

05.02

Are there current support systems for smart buildings?

No

Analysis in progress

05.03

Are there currently specific requirements for technical building systems (for instance in building codes)?

Yes

05.04

Are there current requirements for automatics (for instance in building codes)?

Yes

 For control systems

05.05

Chosen option A or B for heating systems (inspection or other measures)

A

05.06

Number of heating inspections; reports per year (if option A)

Unknown

+/- 5,000 attestations/year after the installation of a boiler

The administration only receives periodic inspection attestations for installations that do not comply with the requirements.
This situation changes from 2020 onwards: all control attestations must be sent to the administration.

05.07

Chosen option A or B for cooling systems (inspection or other measures)

A

05.08

Number of air-conditioning / cooling system inspections; reports per year (if option A)

+/- 100/year

05.09

Is there a national database for heating inspections?

Regional database for the attestations of acceptances and periodic inspection (for periodic inspection, only when the installation does not meet the requirements.)

EPBD is a regional competence in Belgium.

This situation changes from 2020 onwards: all control attestations must be sent to the administration.

05.10

Is there a national database for cooling / air-conditioning inspections?

No real regional database

Given the 'small' number of facilities involved, administrative follow-up is carried out on the basis of an excel table.

05.11

Are inspection databases combined with EPC databases for registration of EPCs and inspection reports?

Not yet but scheduled
