39 good ideas for better energy efficiency

Polarstern is helping the actors involved in the “Confederation: exemplary in energy” initiative communicate their commitment to greater energy efficiency and the transition to renewable energy. The 39 joint measures adopted by the initiative are also an inspiration for other organisations with ambitions in the field of sustainability.

The Federal Council intends to increase energy efficiency in the federal administration and parastatal enterprises by 25% between 2006 and 2020. The participating actors are planning and coordinating some of their measures within the framework of the Confederation: exemplary in energy initiative.

Currently the actors are the Civil Federal Administration, the DDPS, Swiss Post, Genève Aéroport, SBB, Skyguide, Swisscom, and the ETH Domain, which spans ETH Zurich, EPF Lausanne, the Paul Scherrer Institute, the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL), the Swiss Federal Laboratories for Materials Science and Technology (Empa), the Swiss Federal Institute of Aquatic Science and Technology (EAWAG) and the ETH Board.

The Confederation: exemplary in energy initiative plan has defined 39 joint measures in the three action areas buildings and renewable energy, mobility, and data centres and green IT. The following list gives a compact explanation of the measures and the relevant targets and indicators. You’ll find a full description of each measure on the “Confederation: exemplary in energy” website.

Action area buildings and renewable energy

1. Energy-efficient new and converted buildings
The actors’ strategies for buildings and sites are guided by best practice. For specific building standards they are based as much as possible on existing labels, such as MINERGIE-P-ECO.
For sites, strategies with an aggregate energy review are appropriate.

Indicator: standards existing, published and complied with.

Target: 100% compliance with the standards from 1 January 2016.


2. Analyses of potential of waste heat and renewable energy
The actors each draw up an analysis of potential. It is intended to show the extent to which waste heat could be utilised and renewable energy produced on their sites and in their buildings and what this would cost. The FOE is consolidating these analyses and drawing up a master plan called “New renewable energy in the federal government and parastatal enterprises”.

Indicator: analysis of potential available.

Target: analyses of potential available.


3. No new fossil-fuel powered heating systems
The actors no longer build any fossil-fuel operated heating systems in their buildings. This also applies explicitly when replacing existing systems. Justifiable exceptions are possible, for example for special sites or functions. In such cases renewable substitute energies such as biogas should be used or, as the second priority, emissions should be offset by CO2 reduction measures.

Indicator: newly-installed heating systems operated without fossil fuels.

Target: 100% from 1 January 2016.


4. Full cost accounting of energy efficiency
In order to evaluate energy efficiency measures, the actors use life cycle costs (LCC) or total cost of ownership (TCO) approaches. Investments in energy efficiency measures that pay for themselves over the life cycle of a measure are implemented. The application of the methodology is made public in a strategy paper.

Indicator: 1–2 case studies available.

Target: available from 1 January 2017.


5. Energy-efficient lighting
The actors now only procure lighting that is guided by the best practice principle, i.e. which is based on the latest and most energy-efficient technology. In the case of outdoor lighting, special attention is paid to nature-related issues, especially light pollution.

Indicator: internal standards available and complied with.

Target: 100% from 1 January 2016.


6. Energy-efficient cooling machines
The actors plan, procure and operate cooling machines to best practice standards: first of all, generation of heat /cold has to be designed integrally and, if possible, without a cooling machine (taking account of the annual heat / cold curve, use of waste heat, free cooling). If a cooling machine is nevertheless required, it has to be implemented according to the latest SIA standard; in addition, a greenhouse gas effect evaluation should be carried out.

Indicator: proportion of cooling machines procured in compliance with the requirements.

Target: 100% from 1 January 2016.


7. Energy-efficient sanitation facilities
Cold water alone is the standard for hand-washing and similar activities in toilet blocks and comparable facilities in new and renovated buildings. In addition, the actors now only procure sanitary ware in energy class A, except for showers (energy class B).

Indicator: internal standards available and complied with.

Target: 100% from 1 January 2016.


8. Energy-efficient electromotors
When installing (in new and replacement buildings) new electrical building apparatus (ventilation, airconditioning, cooling, sanitary), electromotors and other electrical apparatus (e.g. lifts, conveying equipment, compressors), the actors use the most efficient electromotors in each case (best practice strategy).

Indicator: internal standards available and complied with.

Target: 100% from 1 January 2016.


9. Building technology with operating optimisationregime
The actors subject their building apparatus to continuous operating optimisation (OO). Recognised measures for increasing energy efficiency are being implemented constantly. In addition, whenever a new apparatus is commissioned in a building, an acceptance procedure is consistently carried out; any defects are rectified.

Indicator: consumption of apparatus with a continuous OO regime as a percentage of total annual energy consumption.

Target: 60% (by 2020).


10. Procurement of green power and power from renewable energy
The actors will gradually increase their proportion of green power (naturemade star or equivalent) to 20% by 2020. The remaining power requirement should be met by no later than 1 January 2020 exclusively with power from renewable energy sources.

Indicator: 1. green power as a percentage of total consumption, 2. power obtained from renewable energy as a percentage of total consumption.

Target (not including rail traction power): 1. 20% (by 2020), 2. 80% (by 2020).


11. Mobility concepts for buildings
From now on, the players only construct new buildings with more than 50 permanent employees when there is an overriding mobility concept, and take the traffic volume into consideration already when choosing the location. The concept comprises minimum requirements for opening up areas with public transport (PT) and non-motorised traffic, as well as measures to reduce induced traffic and promote energy-efficient mobility.

Indicator: new buildings (> 50 permanent jobs) as a percentage of all new buildings (> 50 permanent jobs) with a mobility concept.

Target: 100% from 1 January 2016.


12. Creation of ecofunds
The actors each create an ecofund of their own. These ecofunds are financed out of the reimbursement of the CO2 and VOC levies and out of further reimbursements of monies in connection with environmental incentive levies, provided that these are not to be used by law or under a performance agreement for other purposes, or from other financing sources. The ecofunds finance measures in the energy or environmental sector.

Indicator: % of reimbursed environmental incentive levies that flow into the ecofund

Target: Vehicles used for < 2 hours per day are incorporated into the vehicle pool.


28. Provision of charging stations for electric vehicles
Parking spaces at larger sites are equipped with charging facilities for ordinary electric vehicles, for example electric cars, electric scooters and e-bikes. In new buildings, plans must ensure the subsequent installation of charging stations for electric vehicles.

Indicator: % of sites (> 500 employees) with charging facilities for electric vehicles.

Target: 100% (by 2020).


Action area data centres and green IT

29. Full cost accounting of energy efficiency in procurement
The actors assess and select for a predetermined specification their IT infrastructure according to the total cost of ownership (TCO) approach, including energy consumption. Energy consumption must be disproportionally overweighted here, unlike with the purely TCO approach.

Indicator: % of the IT appliances evaluated according to the description of measures in new calls for tender.

Target: 100% from 1 January 2015.


30. Specifications for new servers and new data centre hardware
The actors systematically call for joint state-of-theart specifications when procuring new servers and further data centre hardware. The state-of-theart specifications are based on existing labels (for example, 80 PLUS Gold-Label or ENERGY STAR Programme Requirements for Computer Servers) or standards.

Indicator: % of compliant servers and further hardware in the data centre in new calls for tender.

Target: 100% from 1 January 2015.


31. Highly energy-efficient data centres
The actors implement the most energy-efficient concepts and technologies in the data centres’ infrastructure systems (ventilation, cooling, uninterrupted power supply, lighting).

Indicator: average PUE value (power usage effectiveness) over all of the data centres. The PUE value is defined as the ratio of the total electrical energy consumption of the data centre to the energy consumption of the IT equipment.

Target: < 1.3 by 2030. (In new and larger data centres, smaller PUE values are expected, while best efforts are expected in smaller data centres).


32. Pushing passive cooling solutions in data centres
The actors push the use of energy-efficient passive cooling solutions without cooling machines by using the air conditioning range permissible for servers as per current standards. As first measure, in existing data centres with conventional cooling, the cold operating temperature is raised to at least 26 °C.

Indicator: 1st part: existing data centre surface area with temperature
> 26 °C; 2nd part: data centre surface area with extended temperature range or with passive cooling.

35. Monitoring and evaluation of new technologies
The actors monitor or evaluate new technologies with energy-efficiency potential and operate a technology board within the Confederation: exemplary in energy initiative.

Indicator: number of technologies evaluated.

Target: at least 1 per year.


36. Promotion of waste heat recovery
The actors promote the feeding of their surplus heat from civil IT production into district heating grids, provided that suitable heat customers exist and a contractor is prepared to take on the project in full. Financing, planning, construction and operation from the heat production site are a matter for the contractor.

Indicator: % use of surplus waste heat.

Target: 50% by 2030 (data centres of > 250 sq. m.).


37. Promotion of economy mode at computer workstations
The actors ensure that, when not in use, computer workstations switch to the idle state after a predetermined time.

Indicator: % of workstations with active power management.

Target: 90% by 2015.


38. Promotion of energy-efficient printing solutions
The actors optimise the number of printers per employee and implement modern printing solutions in the office area, such as the follow-me-printing function. As a result, printer operation is optimised and paper and power can be saved.

Indicator: no. of employees per printer; kg of paper per employee.

Target: 100 employees per printer or at smaller sites a maximum of 1 printer by 2020; 5 kg of paper per employee per year (= approx. 1,000 A4 sheets) by 2020.


39. Promoting re-use of appliances
The actors promote re-use of old, but still-serviceable, equipment by passing on old PCs to specialised companies, aid agencies or by giving them to employees. Equipment that has to be disposed of is processed only by certified recycling companies. (In order to ensure energy efficiency, the actors can define additional criteria, for example that only equipment less than 8 years old should continue to be used.)

Indicator: guidelines for recycling no-longer-used equipment are available.

Target: 100% by 2015.
