Specific guidance for sub-metering of thermal energy in multi-unit buildings (implementation of Articles 9-11 of Directive 2012/27/EU on energy efficiency (updated version))
Upon request by the European Commission, a series of guidelines were published to support Member States authorities and building owners in implementing art. 9-11 of the Energy Efficiency Directive (EED 2012/27/EU) concerning the consumption of thermal energy for heating, cooling and hot water in multi-apartment and multi-purpose buildings.
The general idea is to ensure that users of such buildings have the right incentives and sufficient information to adopt energy-efficient practices. Inducing energy-efficient behaviour among building users should be seen as a complement rather than an alternative to actions aimed to improve energy efficiency at building level, such as improvements in the envelope or the central heating system.
More specifically, the guidance aims to:
- ensure that individual heat meters or heat cost allocators are installed in existing buildings (EED Art. 9(3) 2nd subparagraph) enabling consumption-based allocation of costs (EED Art. 9(3) last subparagraph), and
- ensure provision of consumption based billing and "frequent"/sub-annual billing information in respect of thermal energy for space heating, space cooling and hot tap water (EED Art. 10(1) & Annex VII).
The guidelines deal with the specification of building classes, and the assessment of the cost-effectiveness of action in respect of individual buildings ("building assessment"). The same approach is recommended both for testing/defining exempted building classes and for assessing individual buildings (as is required in open building classes). Guidance on the use of reference prices, the use of competitive prices discovered in the market, and the use of the current evidence base of research on energy saving. The guidelines also include recommendations for cost allocation and examples from regulatory practice.
