Energy Design Review

An Energy Design Review is the most efficient way to reduce long-term operating energy costs at little to no additional investment costs for a new facility yet to be built. 

Who is it for?

  • for companies planning on large expansions or reconstructions or new developments of industrial facilities

What can you achieve with an EDR?

  • Reduced long-term energy expenses from the first day
  • Decreased long-term energy intensity and improved operational efficiency
  • Significant reduction of total cost of ownership (TCO = investment and operating costs)

While every architect and design team these days possess valuable knowledge for energy efficiency in the design of factory buildings, employing a specialist can significantly further reduce operating costs that easily cover the additional required investment in only several months and generate savings for the long-term.

The key is to make energy efficiency changes to your plant while the new plant is only in the design phase so the energy consumption of the factory is reduced to its optimum from the beginning

Typical examples:

  • Design engineers are usually asked to design a new building or installation at lowest investment costs possible while still complying with minimal design requirements. This can lead to a situation where an HVAC system is installed which despite its lower investment costs of, say, 20 000€ uses that same amount of money in increased annual operation costs compared to a superior system with better controls. In other words, an investment into the more expensive system has a payback of only one year and delivers significant savings each year thereafter. What seemed more expensive on first sight is actually a much more economic solution in the mid- to  long-term. 
  • Another example are air handling units which usually these days include efficient heat recuperation and low voltage high efficiency motors. The supplier is happy to have saved his customer significant energy costs with this state-of-the-art equipment. However, even this new installation harbors further potential for energy optimization once adapted to the specific production scenario it is used in and given that its controls allow for such fine-tuning. 

The key to successful energy management is to install the equipment, that you plan to invest in at your new facility,  with sufficient control features to make it adaptable to the given needs of production and to changing conditions such as season, lighting levels etc. This is what an EDR can provide you with before you commit to the investment. 


How the EDR process works

  • phase 1Kick-off and data collection (week 1)
    • Layouts, technical descriptions of buildings, services and appliances, production
    • Data of energy consumption of appliances planned for the building
    • Expected plant / processes utilization schemes
  • phase 2Available data assessment (week 2)
    • Establisment of the future energy baseline
  • phase 32days site visit (week 3)
    • Meetings with plant management and the design team for the new factory
    • Factory tour, familiarization with idnustrial processes and investment plans
    • Workshop discussing these processes and potential energy savings
  • phase 4Energy Design Review report (within 10 days)
    • Data evaluation and reporting
    • List of identified saving opportunities with individual savings calculation
  • phase 5Follow-up assistance (suggested within 5 days)
    • Incorporating clients feedback into the final report


What is the difference between an energy design review and a legal energy audit?

The difference is big. An energy design review is performed during the early phase of construction or reconstruction of a factory, whereas an energy audit involves halls which are already in operation. If you plan an expansion or construction of a new production hall, an energy design review is a very effective way of significantly reducing future energy costs. If your hall is already in use and you want to make energy savings, we advise you to use our service ‘Energy savings in industry - QUEST’.

Is the energy design review time-consuming?

As soon as we collect all the necessary data, an energy design review project can be completed within one to two weeks. For more details of its scope and process please read ‘How EDR works’.

When is it best moment to start an energy design review?

Generally speaking, the sooner the better. However, if an energy design review starts at a moment when the general design features of a building have not yet been determined, we cannot undertake an EDR. By contrast, if the start is just before or after the start of construction, it may be difficult to reverse some decisions that affect future energy consumption, and, at worst, there may be delays and cost overruns involving the whole construction. We are ready to discuss with you the best timing for conducting an EDR.
