The ‘Energielotsen’ (Energy Guides) in the Hannover region (around 672,000 inhabitants in proKlima municipalities) in Germany are architects or engineers who consult clients on energy efficiency measures for buildings during the whole construction or refurbishment process. Regarding new build, the programme provided financial support for around 300 very energy-efficient new homes from 2005 to 2010. In the area addressed by the proKlima fund, 3,255 new homes were constructed between 2005 and 2010 and proKlima has provided financial and technical support for 11.1% of them. In 2010 alone, almost 70 new buildings and more than 100 existing buildings undergoing energy-efficient refurbishment received financial support for Energy Guides.
‘Energielotsen’ (Energy Guides) are responsible for ensuring energy efficiency quality in planning by the architects and also for the good implementation, by working with the construction companies and contractors. An Energy Guide also works together with independent quality management companies (proKlima f, p. 9). These are architects and engineers who support the Energy Guide and check heating technology, ventilation technology, passive house building shell, cogeneration of heat and power, in residential and non-residential buildings (proKlima c/ proKlima e). Summarised, the Energy Guide informs, consults and supports clients throughout the whole planning and construction process in new build and refurbishment.
To qualify as an Energy Guide, the candidates have to fulfil certain criteria, including experience in the realisation of the Passive House standard and good knowledge about available financial incentives (proKlima d). The clients are supported with up to €500 for the consultation of an Energy Guide and if they finally build a Passive House, this will qualify for an additional grant of €6,000 (proKlima f, p. 9). In order to ensure compliance, evidence has to be provided that Passive House requirements are met: heating energy consumption does not exceed 15 kWh/m2/yr and the primary energy demand is not higher than 120 kWh/m2/yr.
The programme is implemented by the Enercity fund proKlima, which is a climate protection fund and a model for local, voluntary and co-operative implementation of climate protection. The Hannover municipal energy company Stadtwerke Hannover and the cities of Hannover, Laatzen, Hemmingen, Ronnenberg, Seelze, and Langenhaagen finance the fund. The unique fund approved grants of €45 million between 1998 and 2010 and induced reductions in annual CO2 emissions of ca. 93,500 metric tons (proKlima a, p. 35). Another €2.9 million were granted in 2011 (proKlima h, p.22), with expected annual CO2 emissions reductions of more than 7,000 metric tons. Selection criteria for setting up a specific programme are CO2 emissions reduction efficiency (€ per ton of avoided emissions), absolute CO2 reduction, multiplier effect and the innovation degree of the measure promoted (proKlima b).
In 2010, 1,622 applications for all of the proKlima support programmes were approved and proKlima invested €2.7 million in its general support programmes (proKlima a, p. 26-27). This is a decline compared to 2009 and is related to the cutbacks of federal grants and soft loans, which can be combined with proKlima subsidies. €0.15 million were granted for Energy Guides to 108 buildings undergoing energy-efficient refurbishment. Funding of the Energy Guides for the 67 new Passive Houses is not explicitly mentioned in the report (proKlima a). With €2.9 million in 2011, the overall figure was increased again (proKlima h, p. 22). In addition to the general financial incentive programmes, the Fund spends around € 0.8 million/yr each for (1) individual projects and (2) information campaigns and programmes.
There is also a German federal programme On-Site Energy Saving Advice (Germ.: Vor-Ort Energiesparberatung). However, it only subsidises two services from energy experts: building assessments and outlining modernisation options. The complimentary service of the Energy Guide Programme also informs clients about funding options (during the construction/refurbishment process), supports clients with the selection of the modernisation concept and with the application process for further funding options (proKlima k, p. 1).
The Enercity fund ProKlima wanted to promote the Ultra-Low-Energy Building concept of Passive Houses but noticed that investors and other market actors faced barriers in implementing this concept. Investors had difficulties in finding contractors capable of the required construction techniques, and there was a lack of quality control.
The ‘Energielotsen’ (Energy Guides) in the Hannover region in Germany is an energy advice and assistance programme, which helps clients to build their new home in an energy efficient manner, preferably in passive house standard. The service is also available for retrofitting of existing buildings, combined heat and power (CHP), solar (water) heating, and schools. The Energy Guides are architects or engineers who consult clients on energy efficiency measures for buildings during the whole construction or refurbishment process. The overall aim of the ‘Energielotsen’ programme is to provide the best possible energy efficiency consulting for the building or retrofitting process in order to guarantee compliance with a high building energy efficiency standard.
Energy Guides must assess the whole building in order to avoid lost opportunities. This covers, in principle, all passive design and active technology options. However, whether all recommendations are implemented is up to the investor.
‘Energy Guides’ is an advisory service for assisting investors in achieving energy-efficient building and refurbishment.
The aim is to achieve that Passive Houses are built. They require a maximum heating energy consumption of 15 kWh/m2/year and a maximum primary energy consumption of 120 kWh/m2/year.
Supply-side actors will benefit if they offer or can participate in the construction of energy-efficient and particularly Passive Houses.
In order to receive grants from the local proKlima climate fund, it is mandatory to assign an Energy Guide with the task of assessing the respective building. The clients may receive up to €500 for the consultation of an Energy Guide and if they finally build a Passive House, up to an additional €6,000 (for a single-family house) (proKlima f, p. 9). In order to ensure compliance, evidence has to be provided that heating energy consumption does not exceed 15 kWh/m2/yr and the primary energy demand is not higher than 120 kWh/m2/yr.
Funding, to a large extent, depends on the complexity of the building project. The more ambitious the energy savings are planned to be (after the project is finished), the higher the costs for the Energy Guide. However, funding also increases with increasing complexity.
Germany’s state owned bank, KfW, also provides further incentives for investors. Again, more ambitious projects receive better loan or grant conditions. Read more in the bigEE good practice policy example on the KfW programmes.
Germany’s Minimum Energy Performance Standard is stipulated in the Energy Saving Ordinance (EnEV) and calculated with the Reference Building Method. Depending on various criteria (e.g. size, location) a building needs to pass certain thresholds. Based on the EnEV, a system was developed that classifies minimum performers from best performers. Both, proKlima and the KfW provide funds via this scheme. It is also linked to the Energy Performance Certificate.
Following the concept of the Energy Guide, proKlima also introduced Electricity Guides and Photo-Voltaic Guides.
The fund that proKlima administers and distributes for energy efficient refurbishment measures is replenished with around €5 million per year. This equates to €3.9 million coming from Stadtwerke Hannover AG, which is the public utility company of the region, €1 million from the local city government of Hannover and ca. €200,000 from some smaller municipalities. The lion’s share of the fund coming from the utility company is always from revenues of the preceding year.
The website also points to various online-calculators so that users can assess their electricity bill enabling them to find energy saving potential on their own. More personal advice is available at the Enercity Expo Café.
The effects of ProKlima (or its projects) have been evaluated. They comprise programmes for existing and new buildings, renewable energy, schools, CHP, non-residential buildings and electricity guides. It is estimated that €2.6 million resulted in investments of €33 million. In addition, 260 jobs were secured or created. Moreover, 50% of the added value remains in the region of Hannover and the wider area of Lower Saxony.
Compared to traditional energy advice schemes that only provide recommendations before the investor’s decision and try to stimulate the latter, the Energy Guides are highly innovative in the repeated assistance carrying the investor through the implementation of the project to ensure energy efficiency success and quality.
The most innovative aspect of the policy package is probably that funding is - to a large extent - generated through revenues by the public utility company: Stadtwerke Hannover AG.
The following pre-conditions are necessary to implement Energy Guides (insert name of the policy type):
Agencies or other actors responsible for implementation
The programme is managed by the Enercity fund proKlima.
Funding is provided by proKlima, which receives €3.9 million from Stadtwerke Hannover AG, €1 million from the local city goverment of Hannover and ca. €200,000 from some smaller municipalities. The lion’s share of the fund coming from the utility company is always from revenues of the preceding year (proKlima (g)).
For all its buildings-related schemes, ProKlima relies on the calculation methods required for the German Minimum Energy Performance Standards and Energy Performance Certificates for buildings.
In 1998, several local institutions signed the ‘ProKlima Co-operation Agreement’ and, thus, institutionalised ProKlima – The Enercity Fund, which is responsible for the general administration and implementation of projects in the region.
The proKlima team then developed a proposal for the Energy Guides programme and estimated the savings and costs. Each year, the Board of theproKlima fund decides on priority projects based on greenhouse gas emission reductions achievable per fund used in the projects and programmes. Following the positive decision on the Energy Guides programme, the team implemented it.
The Energy Guides measure does not have a particular energy savings target.
Actors responsible for design
ProKlima fund (local Energy Efficiency Fund and Agency)
Actors responsible for implementation
ProKlima manages the project and is responsible for providing Energy Guide grants to investors. The actual on-site visits are done by the Energy Guides who are engineers or architects with additional qualifications.
ProKlima keeps track of the buildings they support with grants and of the energy savings and greenhouse gas reductions compared to reference buildings that would just have met the requirements of the German Minimum Energy Performance Standards (EnEV).
The impacts of ProKlima (or its projects), have been evaluated. They comprise programmes for existing and new buildings, renewable energy, schools, CHP, non-residential buildings and electricity guides. It is estimated that €2.6 million resulted in investments of €33 million. In addition 260 jobs were secured or created. Moreover, 50% of the added value remains in the region of Hannover and the wider region of Lower Saxony. The total energy savings and greenhouse gas reductions for all programmes are also evaluated on an annual basis.
For Lower Saxony the policy has additional labour market effects. 260 jobs have been saved or created. 50% of added value remains in the region.
proKlima did not publish energy savings from the Energy Guides scheme separately.
In total, ProKlima approved grants of €45 million between 1998 and 2010 and induced reductions in annual CO2 emissions of ca. 93,500 metric tons (proKlima a, p. 35). Another €2.9 million was granted in 2011 (proKlima h, p. 22), with expected annual CO2 emissions reductions of more than 7,000 metric tons.
3,255 new homes were constructed between 2005 and 2010 and proKlima provided financial and technical support for 11.1% of them. In 2010 alone, almost 70 new buildings and more than 100 existing buildings undergoing energy-efficient refurbishment received financial support for Energy Guides.
For 2011, ProKlima approved 89 projects and funds for Energy Guides of €76,509 for existing buildings. 88 new buildings, which needed to meet the passive house standard, received ProKlima grants (ProKlima (h)). While the total is not provided in the source, the grant for Energy Guides for new buildings was at the maximum €500.
Data is only available for ProKlima as a whole. ProKlima invested €2.6 million which led to additional private investments of €33 million (ProKlima (i)).
