02.01

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

Overall value expressed in total primary energy and calculated with the reference building approach

 CO₂ are reported on EPC for information

02.02

Requirements for energy performance of residential buildings in current building code

Better energy indexes (listed below) than the corresponding values of the “reference building” 2015 (new values from 2021):

• Global EP_gl index [kWh/m²] (heating, cooling, hot water, ventilation services)
• Specific energy needs for heating and cooling
• Efficiencies of the technical systems (h_H, h_C, h_W, h_V)

Additional limits for the building envelope:

• H’T Transmission heat transfer coefficient
• Summer effective solar area
• Mass of external walls (or, alternatively, their periodical transmittance)
• U-values of inter-building walls/floors

RES integration (+10% for public buildings)

• 50% share for heating, cooling and domestic hot water
• 50% share only for domestic hot water
• Electric power installed per building footprint unit surface [kW/m²]: 0.02

In the case the required RES integration should not be feasible, the building has to respect a proportionally lower EP_gl limit value

• Minimum requirements are defined according to the 'reference building', being a virtual building which has the same localisation and is geometrically equivalent to that considered in the project, but with thermo-physical characteristics corresponding to the minimum energy requirements in force.
• EP indices are expressed in non-renewable and in total primary energy [kWh/m²].
• Energy parameters of the reference building are listed in Tables 2 and 3 of the Italian Country Report 2020.
• Summer effective solar area limits are illustrated in Table 5 of the Italian Country Report 2020.
• H’_T limits are illustrated in Table 4 of the Italian Country Report 2020.

Second-level major renovation:

• U-value of the concerned surfaces lower than the limit values 

• H'T mean transmission heat transfer coefficient of refurbished building elements lower that the limit value.

• Mean efficiencies of renovated technical systems higher than reference values.

First- and second-level major renovations are defined as follows:

First-level major renovation: 'refurbishment of at least 50% of the envelope and renovation of the heating and/or cooling plant of the entire building'.

Second-level major renovation: 'refurbishment of at least 25% of the external surfaces of the building with or without renovation of the heating and/or cooling plant'.

For U limit values - see Table 6

For H'T limit values – see Table 4

For mean efficiencies limit values - see Table 3

Minor renovation is defined a 'refurbishment of less than 25% of the external surfaces of the building and/or modification of the heating and/or cooling plants'.

For U limit values - see Table 6

For mean efficiencies limit values - see Table 3
