Tasks of Directorate IV/4 – Energy Efficiency and Buildings
• Implementation of Directive (EU) 2018/2002 amending Directive 2012/27/EU on
energy efficiency into national law: In this context unit IV/4 deals with the
national law on energy efficiency: Bundes-Energieeffizienzgesetz, BGBl. I
Nr.72/2014 (EEffG) and with the energy savings by Bundescontracting according
to § 16 EEffG.
• Co-ordination of implementing Directive (EU) 2018/844 amending Directive
2010/31/EU on the energy performance of buildings.
• Co-ordination of the national “heating strategy” (Wärmestrategie).
Tasks of Directorate IV/4 3

History of Bundescontracting
• 1997 Pilot project “Energieeinspar-Contracting”
• 1999 Energy Performance Contracting including 46 public school buildings (2
pools)
• 2002 Ministry council decision called “Bundescontracting 500” for the government
buildings
History and regulatory framework

5. bmnt.gv.at
Regulation
• Energy Efficiency Directive , Art. 5
• Implementation through the national Energy EfficiencyAct, Par. 16
− Energy savings of 48.2 GWh in buildings owned and used by the government
have to be achieved between 2014 and 2020
• Measurement plan defining measures needed to achieve the energy savings
target
− Energy contracting (~ 30 GWh of energy savings)
− Energy management (~2 GWh of energy savings)
− Renovation and floor reduction (~18 GWh of energy savings)
History and regulatory framework

6. bmnt.gv.at
Current projects and achievements
• 29 pools and 276 building units
• EUR 18.3 million total annual energy costs (electricity and heating)
• EUR 3.6 million annual average guaranteed energy savings
• 19.53% energy savings target
• 13.25 t annual CO2-emission savings
Achievements 6

Definition “Bundesgebäude-Contracting”
• This model is aimed at reducing energy demand and CO2 emissions in
governmental buildings.
• Contract between federal agencies (or government) and ESCOs to achieve
guaranteed energy savings in the period of 10 years.
• 80% of saved energy costs are used to cover the investments in energy savings
measures.
• 20% of saved energy costs are returned to the building user.

Project details – main definitions
• Pool -> grouped buildings, located in different places but in the same region; the
same or similar building type
• Building unit -> one or several buildings standing together
• Baseline -> energy demand for space heating and electricity of a pool and building
unit; it is the starting point for the calculation of the energy savings guarantee
• Revision -> substraction of all energy savings which will be achieved not by the
contractor
• Navigator -> monitoring software for invoice

Conclusions
• Energy Performance Contracting is a good model
− Increase energy efficiency of the systems
− Save energy costs and CO2 emissions
• Bundescontracting is the first step towards optimal building energy efficiency
• Having an optimized operational management thanks to the Bundescontracting,
there is a good ground for a building renovation into an “intelligent building”
Conclusions

13. bmnt.gv.at
Recommendations (I)
• Building users and their motivation and involvement is very important
− Contractor has to motivate using individual support and consulting, workshops,
newsletters, excursions, hotline
• Define comfort temperature parameters and implemented technologies before
the start of the project
• Contracting is like a marriage
− All stakeholders should share a common undestanding; expectations must be
clarified at the outset
− Good communication between contractor and building user is essential
Recommendations 13

14. bmnt.gv.at
Recommendations (II)
• What happens after the contracting period?
− Who takes over the responsibility for the systems?
