Energy Efficient Design (Spin II)



Traditionally energy management has been seen as an activity that begins in the operating phase of a project. However, Energy Management Standards, such as ISO 50001, envisage a lifecycle approach to energy management. The lifecycle approach could be defined as the processes applied in the design, procurement, construction, commissioning and operational phases of a project that minimises its energy consumption.

The Energy-Efficient Design (EED) Methodology assists investors to design, construct and commission projects so that they consume the least amount of energy during their subsequent operation. It also places operational-phase energy-management on the design agenda.

The EED Methodology provides investors with a framework to ensure that energy management is addressed at the earliest possible stage, to realise the greatest energy-saving potential with the shortest payback thus complimenting the lifecycle approach envisaged in Energy Management Standards.  

The Energy Efficient Design (EED) Special Working Group (SWG)

In developing the programme of work for this SWG, its members sought to address why energy-efficiency technologies and best practices have not achieved their true potential. The key weakness identified was that design projects are not organised, nor are the design processes in place, to deliver optimum EED. This Special Working Group (SWG) sought to provide a framework for design activities to deliver the most energy-efficient design.

Benefits of the EED Methodology

The benefits of applying this methodology are documented in a number of SEAI-sponsored case studies. Energy-saving potential of up to 50% has been achieved on some projects when compared with business-as-usual design practices.

The benefits of applying the EED Methodology include:

  • It minimises energy consumption in the operational phase.
  • It reduces capital costs in both utilities and processes.
  • It addresses operational-phase energy management during the design phase.
  • It is a knowledge-based and knowledge-generating process that will ensure competitive advantage.
  • It can be readily integrated into existing project and design procedures.

The cost of implementing the EED Methodology in the demonstration projects ranged from 0.2 to 1.0% of overall project cost, with no impact on project schedule and payback of less than one year in most cases. This excludes the benefit of any capital expenditure avoidance.
