About E.V.V.E.1
Mission


Independent and Europe-wide interest group aiming at the promotion of systems that
enhance energy and water savings in the residential sector

and carry out the service of consumption-based billing of energy and water costs
History

Founded in 1993, in Copenhagen, as „European Economic Interest Group“ (EEIG)
Organizational structure


15 member companies and two associated organisations
Represented in 9 EU Member States (Austria, Denmark, France, Germany,
Luxembourg, the Netherlands, Poland, Slovenia and Spain)

Why heating and hot water matter
Domestic homes use more than 80% of their energy for
heating and hot water
 Domestic
homes
are
responsible for 25% of the

 Ca. 80% of the energy used in
domestic homes are due to

Success factors
1) Pay-for-use
Tenant is the main beneficiary of Submetering: fair distribution of costs; transparency
and control over own consumption; savings outweigh the incurred costs; direct rewards
for further energy saving behavior
 Allocation of costs to tenants guarantees maximum energy saving
incentive
Countries with mandatory legislation show higher Submetering penetration rates, resulting
into higher energy savings’ levels

 Mandatory legislation allows to seize Submeterings’ energy saving potential
MS with strong Submetering legislation much easier perform on achieving EU 2020
energy efficiency goals6
3) Enforcement

 Enforcement tools including sanctions ensure effective implementation
(e.g. penalties for non-provided services)

Regular consumption information
Individual consumption data frequently provided by modern radio
technology
Consumption information shows individual cost-cutting potential and
enables tenants to change their heating and water consumption
behaviour
Online-based applications for detailed but clear consumption information
– or classical hard-copy information if preferred
Achieving sustainable change of consumption behaviour
“Only people who know their energy consumption can really
individually manage their energy consumption.”

Executive summary

More needs to be done if we want to achieve EU-wide energy efficiency targets for
2030 and beyond

Energy savings are necessary in the domestic housing sector, especially when it comes
to heating and hot water

With Submetering we have a solution in place which is easily deployable; it has
proved its excellence in the last decades

Submetering empowers the consumer/tenant to
consumption and contribute to energy savings directly

Submetering potential will be seized successfully if:

steer
his/her
own
energy

Costs are directly allocated to beneficiary of energy savings (tenant)

Submetering legislation is made mandatory in all MS

Enforcement of existing and future national legislation is ensured via
sanctions
Billing Information: easy step to realise additional savings on a low cost base
