The Dynamic Perspective of the Energy Performance Certification (EPC)


The E-DYCE vision is to provide an energy performance labeling methodology, that will be closer to building operation condition, and will be able to defend its voluntary status, by the benefits it provides.

E-DYCE is aligned with current EPBD and nZEB definitions and can be applied to any building of any typology, location or smartness level. It aims to generate substantial savings of one energy class, by guiding the user to unlock the potential of free running operation of the building.


E-DYCE innovative approach will be combined with established and widely available tools, to create a methodology capable of implementing scalable, adaptable and accurate Dynamic Energy Performance Certification (DEPC).

The aims to achieve through the project are summarized into the following Strategic Objectives (SO):

SO1. To deliver a methodology for dynamic certification of buildings based on openly available resources and tools for technology and service providers, effectively creating an evolving, technology neutral ecosystem.

This will be made feasible through the creation of:

  • An input data collection architecture, capable of processing a wide range of input
  • A modular framework architecture, capable of featuring an information model for performing dynamic simulations in various data frequencies
  • A pool of accurate and clear feedback to provide to the user, for increasing the user’s awareness about the building operation

SO2. To generate substantial savings of 30kWh/m2 (+1 energy class) in buildings certified through a dynamic scheme, therefore benefiting owner, tenant and the service provider and thus incentivizing all three.


This will be made feasible through the generation of:

  • Significant savings by substantially improving building performance in a large scale and maximizing the diffusion of the results in the European Community

SO3. To leverage the savings generated and reinvest into energy efficient refurbishments and optimization, scaling up the number of buildings certified to the level that can provide policy makers with meaningful data.


This will be made feasible through the creation of:

  • Guidelines and best practices for the implementation of DEPC, through extensive demonstrations in a variety of building typologies and locations

In short, E-DYCE shall:

  • Create a technology-neutral methodology for dynamic labelling, based on maximizing the free running potential of the building and promoting the use of passive and low-cost solutions, instead of mechanical systems.
  • Provide for clear actions of the user and their diminishing effects on the energy consumption, to motivate and improve energy-related behavior.
  • Demonstrate and Validate the methodology, through implementing the developed DEPC in several buildings contributing to the Project.
  • Strengthen the collaboration between energy experts, authorities and building owners, to share the benefits of reliable dynamic certification.
  • Adapt to any level of building typology, climate, smartness and scale, through dynamic simulation of their performance
