Brussels, 16th February 2016

Mandatory versus Voluntary

MANDATORY

• Use legislative means to “force” building owners to improve energy performance

• Trigger points need to be carefully considered

• Can be perceived as heavy handed

VOLUNTARY

• Relies on overcoming consumer inertia to take action based on attractiveness of the offer

• 30+ years of experience shows achievable renovation rates only ~ 1% p.a.

Six trigger points

for

mandatory renovation

1. Within a Specific Timeframe

• Germany – In place for 10 years, the Energy Saving Ordinance contains obligation to improve energy performance (subject to cost-effectiveness) by 2015

• France – 2015 Energy transition law includes obligation for private residential building owners to renovate their buildings by 2025 where the primary energy consumption exceeds 330 kWh/m2a (= classes F & G).

2. When undertaking maintenance work

• The French energy transition law includes requirements for upgrading the energy performance of external façades and roofs when maintenance or improvement work is planned on the respective building components.

3. When renting a property

• United Kingdom - From April 2018, private residential and non-residential properties in the lowest two classes, F and G, will need to be improved in order to be let out to tenants.

• Flanders Region of Belgium - Since January 2015, residential properties need to meet certain minimum requirements for roof insulation

4. At change of building use

• Denmark - minimum energy requirements for building components in case of change of building use. Examples are:

– conversion of an outbuilding to accommodation

– conversion of usable roof space to accommodation

5. When changing a boiler

• Baden-Württemberg, Germany – options when changing a boiler (chart):

• Bolzano, Italy -renewable energy sources must provide 25% heating and 60% hot water.

• Requirement can also be met through energy efficiency measures

6. When extending a building

Italy - various regions and cities have introduced mandatory building performance upgrades in case of extension:

• Autonomous Province of Bolzano

• Region of Valle D’Aosta

• Trento Province

• Torino city

Mandatory Renovation - Recommendations

• 3% annual renovation requirement for central government buildings (EED article 5) should be extended to ALL public buildings.

• Over time, buildings in the lowest energy performance classes should be deemed unsuitable for occupation. Options include: – Sale or rental of a property could become conditional on meeting

minimum energy performance requirements – All buildings could be set a minimum energy performance threshold

target (varied according to building type) within a given time frame

• Social housing should be in the top quartile energy performance • Any extension, change of use or addition to existing buildings

should be conditional on improving the overall energy performance.

• Change of heating or cooling equipment, or undertaking maintenance work on the building should be accompanied by a requirement to improve building energy performance

Five best practice cases

of

voluntary schemes

1. Stroomversnelling (NL)

• Agreement between social housing sector, construction companies, government and banks.

• Renovation of social housing to net zero energy at no cost to tenants

• Installed within 10 days.

• Energy performance guarantee of 30 years.

2. KredEx (Estonia)

• €72M revolving fund for renovation of apartment blocks

• Combines EU funding (ERDF) and state support, backed by state guarantee

• Loans + Grant linked to renovation level

• >1000 buildings renovated since 2009

• Average saving on energy bills = 40%

3. KfW (Germany)

• Long-standing, large scale support programme for building energy performance improvement

• Annual public budget (all buildings) ~ €1.8 bn/a

• Largest per capita renovation scheme in Europe (€16/person p.a.)

• Support geared towards level of renovation

• “KfW Efficiency House” an established brand

• Very low interest loans (~0.75%)

4. Habiter Mieux (France)

• Large scale national programme targeting fuel poor and low income households

• Aims to renovate 50,000 dwellings p.a.

• Min. 25% energy saving (actual to date > 40%)

• Energy Efficiency Ambassadors used to identify low‐income households

• Supported by energy suppliers as part of their Energy Efficiency Obligation

5. Carbon and Energy Fund (UK)

• Dedicated expert service for UK public sector.

• “Ready to wear” Energy Service PerformanceContracts for complex building renovation.

• Guaranteed savings.

• Streamlining of procedures accelerates thetendering process by up to one year.
