of 14 October 2020

supplementing Directive (EU) 2010/31/EU of the European Parliament and of the Council by establishing an optional common European Union scheme for rating the smart readiness of buildings

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Directive 2010/31/EU of the European Parliament and the Council of 19 May 2010 on the energy performance of buildings (1), and in particular Article 8(10) thereof,

ANNEX I

Calculation of smart readiness scores

1.

The smart readiness of a building or building unit reflects the capabilities of the building or building unit to adapt its operation to the needs of the occupants and the grid, and to improve its energy efficiency and overall in-use performance.

2.

The smart readiness of a building or building unit is determined on the basis of the assessment of smart-ready services present or planned in, or relevant for, the building or building unit, and their functionality level.

3.

The smart readiness of a building or building unit is expressed by a rating that derives from a total smart readiness score expressed as a percentage and that represents the ratio between the smart readiness of the building or building unit compared to the maximum smart readiness that it could reach.

4.

The calculation of the smart readiness scores is based on pre-defined weighting factors in line with Annexes III, V and VII, the value of which may depend on climatic conditions and other relevant aspects, such as the type of building.

ANNEX III

Weighting of impact criteria in key functionalities

1.

Each impact criterion set out in Annex II of this Regulation is considered for only one of the three key functionalities, as set out in points 2 to 4. For each key functionality, Member States shall define the respective weighting factors of relevant impact criteria.

2.

For the ‘energy performance and operation’ key functionality, the relevant impact criteria are ‘energy efficiency’ and ‘maintenance and fault prediction’.

3.

For the ‘response to user needs’ key functionality, the relevant impact criteria are ‘comfort’, ‘convenience’, ‘information to occupants’ and ‘health, well-being & accessibility’.

4.

For the ‘energy flexibility’ key functionality, the relevant impact criterion is ‘energy flexibility & storage’.

ANNEX V

Weighting of technical domains

1.

Each technical domain is weighted for each of the impact criterion and the weighting factors characterise the influence of the technical domain on the impact criterion.

2.

Technical domains’ weighting factors are expressed as a percentage, and for each impact criterion, the sum of the weighting factors of the technical domains equals to 100 %.

3.

| (a) | The climatic zone's energy balance for the weighting factors of ‘heating’, ‘cooling’, ‘domestic hot water’, ‘ventilation’, ‘lighting’, and ‘electricity’ technical domains along the ‘energy efficiency’, ‘maintenance and prediction’ and ‘energy flexibility and storage’ impact criteria; |
| --- | --- |

(a)

The climatic zone's energy balance for the weighting factors of ‘heating’, ‘cooling’, ‘domestic hot water’, ‘ventilation’, ‘lighting’, and ‘electricity’ technical domains along the ‘energy efficiency’, ‘maintenance and prediction’ and ‘energy flexibility and storage’ impact criteria;

| (b) | for all other cases: weighting factors that are either fixed or equally distributed. |
| --- | --- |

(b)

for all other cases: weighting factors that are either fixed or equally distributed.

4.

Member States define the climatic zones that are used, where relevant, in the determination of weighting factors. For this purpose, Member States may use, where available, relevant Union guidance.

5.

The weighting factors of technical domains may differ between residential and non-residential buildings for some impact criteria.

6.

Member States define the weighting factors and, for this purpose, are encouraged to use, where available, relevant Union guidance. They may also take into account possible impacts from climate change.

ANNEX VI

Smart ready service catalogue

1.

For the purpose of calculating smart readiness scores in accordance with the methodology set out in Annex I, Member States make available at least one smart-ready catalogue to be used by experts as the basis for identifying and assessing smart-ready services.

2.

A smart-ready service catalogue includes the list of smart-ready services to be considered for calculating the smart readiness score, related functionality levels, and corresponding individual scores for the impact criteria.

3.

The definition and any subsequent update of smart-ready catalogues reflect the current state of the art of smart-ready technologies.

4.

Member States are encouraged to provide guidelines to experts on the most effective way to identify and assess smart-ready services using, where available, relevant Union guidance.

5.

Member States may decide to make available several smart-ready catalogues, for instance for different building types.

---

ANNEX VII

Possible adaptation of the standard calculation process

1.

To avoid unfairly penalising a building or building unit, some smart-ready services may be omitted in the calculation of the smart readiness scores, in case those services are not relevant for that building or building unit.

2.

Member States define the conditions under which such adaptations are relevant and allowed.

3.

Weighting factors of those technical domains for which the (climatic) energy balance approach would be used under the standard calculation may be calculated on the basis of the consumptions as evaluated in the energy performance certificate of the building or building unit in question.

ANNEX VIII

Smart readiness rating

1.

The smart readiness rating is expressed on the basis of seven smart readiness classes, from highest smart readiness to lowest smart readiness.

2.

Each smart readiness class corresponds to a range of total smart readiness scores as follows: 90 – 100 %; 80 – 90 %; 65 – 80 %; 50 - 65 %; 35 – 50 %; 20 – 35 %; < 20 %.
