Newsletter June 2012


Dear Re-Commissioning community and interested readers!
Welcome to this first edition of the Re-Co newsletter. Whenever you will see this logo, most likely somebody from the Re-Co project is close by. 
The general goal of Re-Co is pretty simple: reducing energy cost through optimization of existing building technology systems and user behaviour. Our concrete target is 10% primary energy savings through no-or-low-cost measures. We focus on existing non-residential buildings, namely in the health sector, universities and office buildings. What is important to us as external consultants is to join forces with the building management and on-site technical personal. In other words: success in Re-Commissioning projects strongly depends on mutual trust, support and learning.
To achieve our goal, we build on 5 key components:
  1. Energy information systems,
  2. Data analysis and selected measurements,
  3. Optimization of existing building technology systems,
  4. Information and motivation of building occupants and
  5. Performance measurement or quality assurance instruments.

The Re-Co process follows a standard Plan-Do-Check-Act management cycle and is compatible with energy management systems as described for example in ISO 50001/EN 16001.  Stefan Plesser from edb provides some more insight on our understanding of “Re-Commissioning Services” later on.
In the Re-Co project, energy efficiency engineers, economists and marketing experts from 10 project partners are joining forces to develop Re-Commissioning services and markets in 8 European countries.

More concretely all Re-Co partners execute real world Re-Commissioning projects together with their national building partners. These pilot projects aim at demonstrating the technical feasibility and financial viability of the Re-Commissioning services in complex non-residential buildings. Klemens Leutgöb from e7 gives you an overview of pilot projects in the article about Re-Commissioning services in practice.
Secondly, Re-Co Project partners mutually support implementation of pilot projects with state of the art knowhow and experiences. The internal Re-Co expert platform facilitates capacity-building through open sharing, training, testing and advancing of Re-Commissioning strategies, tools and advice between project partners. Once finalized, the developed Re-Commissioning approach and lessons learned will be made publicly and will be promoted through reports, workshops, presentations and publications.
And last but not least, all partners execute a national or regional dissemination and networking strategy to spread Re-Commissioning experiences and good practice examples. The goal is to initiate further Re-Commissioning projects and to develop and strengthen Re-Commissioning services in Europe. our public internet platform. Over the course of the project you will find there descriptions of our pilot projects, downloads on our common Re-Commissioning procedure and we will report also on our lessons learned (including failures). And maybe we will even have a collection of links to great energy efficiency video clips. If you want to be updated, please provide us with your contact details, if you haven’t already done so. 
We hope you will find this and the future 3 editions of the Re-Co newsletter inspiring for your day to day energy efficiency business. For further details, you are welcome to contact your national Re-Co partner, whom you find listed in this newsletter.
Re-Co project – Re-Commissioning – Raising Energy Performance in Existing Non-Residential Buildings is supported by the Intelligent Energy – Europe (IEE) programme of the European Commission.


Buildings are complex systems. They are designed, built, operated and used by countless people over decades. It is therefore a huge challenge to keep these buildings running with optimal performance. And in fact: many buildings don’t! Research has shown energy saving potential in commercial buildings between 5 and 30% that can be used simply by improving the way they are operated and used. 
This is where Re-Commissioning – Re-Co in short – comes into play. Re-Co Services offer building owners a straight forward approach to make use of these “low hanging fruits” of energy savings. Following a clear methodology the building operations can be optimized cost effectively and without mayor investments for retrofits. These are the five steps of Re-Co Services for your building:
  1. Design: The Re-Co Services Consultant (Re-Co SC) creates a rough overview of the owners building stock and works out the individual strategic objectives for the building owner and corresponding success indicators. Objectives may be for example improving energy efficiency, reducing operating cost or improving user comfort. 
  2. Investigation: The Re-Co SC investigates the building stock, identifies high potentials and defines specific measures of improvement and a plan for their implementation. The owner will receive a clear calculation of costs and benefits of each measure to decide about the implementation. A concept for evaluation – usually a suitable technical metering system – is defined and installed.
  3. Implementation: The measures are being implemented. All cost and timelines are documented. At this point building operations are actually starting to improve!
  4. Evaluation: All measures are evaluated using individual approach according to the success indicators. The evaluation shows the individual cost effectiveness of each measure and the amortization of the whole Re-Co Service. You will be surprised how fast you can save money and improve your building!
  5. Continuity: Re-Co Services are intended to come and stay! The metering concept and the success indicators are great tools to continuously monitor the performance of your buildings, to maintain the savings and to even indentify further measures of improvement.
Re-Co Services use a comprehensive approach to optimize your building. And they have shown amazing savings in numerous cases by tackling a variety of issues in modern buildings. Here are just some of the options Re-Co Services offer to building owners:
  • Technical optimization: Complex buildings undergo changes in usage. By checking and adjusting set point, air exchange rates and schedules to the actual use energy consumption can be significantly reduced.
  • Coaching: Users can make a difference! Whether it’s a room temperature, quick ventilation via windows or shutting down the computer during lunchtime: a Re-Co coach can show your employees easy and effective ways to save energy and even improve comfort in the office!
  • Energy Administration: A Re-Co SC can help you to implement a cost-by-cause concept in your buildings. Accounting energy to the individual units of your company or renters gives clear information and saving opportunities to all building users.

There are lots of saving potentials you can indentify in your Re-Co project. And the biggest advantage is the payback time: since Re-Co Services target at low- or no-investment measures you will actually start saving money after less than three years!


The Re-Co project demonstrates that Re-Commissioning is working in building operation practice. This is done by the implementation of altogether 15 pilot projects covering all in the project participating countries.

All pilot projects are realised in comparatively complex buildings (hospitals, universities and one public buildings pool) addressing low-or-no cost measures in existing building technologies like HVAC, controls, electrical or compressed air systems with a comprehensive look at all consumption media (electricity, heating, cooling, compressed air and water).

Re-Commissioning in these pilot projects builds on 5 key components already mentioned in the introduction of this newsletter.

The pilots are implemented using a specific mixture of inputs from in-house personnel as well as external expertise from building technology consultants, which are part of the Re-Co project team. The terms and conditions of collaboration of internal and external experts are precisely defined in specific co-operation agreements.

All pilot projects have been already kicked off and a first handful of low-or-no cost measures in existing building technologies have already been identified. In their further process the pilots aim at implementing and verifying savings of at least 10% of primary energy without major investments (refurbishment, renewal, backfitting) in building technologies thus demonstrating the technical feasibility and financial viability of the Re-Commissioning process in complex existing non-residential buildings.

On the following 3 pages you are invited to make a short introductory tour through our pilot projects. And in our next newsletters we will let you know, what have we learned and what have we achieved. 






Re-Co approach is in the public still relatively little- known. Our survey on Re-Commissioning performed from March to May 2012 has shown that more than two thirds of people, who filled in the questionnaire, have not yet heard about Re-Commissioning, though after reading a short explanation of the Re-Co concept the fast majority of them has found it easy to understand.
Within the survey we have until now all together, through the web application and direct interviews, collected 181 questionnaires from 10 countries. 76,8% of all organizations which partici-pated in the survey find energy efficiency very or extremely important. You will be able of reading more information on the survey results in our next issue of the Re-Co newsletter in autumn 2012. Until then we would one more time like to thank all of those, who took their time to participate in our survey and thus giving us valuable information for our future work.
