About TIMEPAC

Towards Innovative Methods for Energy Performance Assessment and Certification of Buildings (TIMEPAC) is a Horizon 2020 research project.

Europe’s building stock covers some 25 billion square metres of floor space, of which 75% is residential. Therefore retrofitting plays a major role in achieving the climate targets set for 2050. The ongoing revision of the EU Energy Performance of Buildings Directive (EPBD) is therefore crucial for tackling climate change and energy poverty.

This is TIMEPAC’s starting point – turning goals into action by transforming the entire Energy Performance Certification (EPC) process. 

As valued as the EPC is, some doubt exists as to whether it actually reflects real building conditions. There is clearly a trade-off between the cost of issuing a detailed and tailored EPC and the willingness of customers to pay for it. Current EPCs are cheap, but they are not investment-grade documents and follow a static approach.

Our approach

Transversal Deployment Scenarios

TIMEPAC will improve the existing certification process across countries through Transversal Deployment Scenarios. Each TDS encompasses various stages of the EPC workflow (generation, storage, analysis, and exploitation), involving multiple stakeholders (research groups, energy agencies, ESCOS, etc.) and resources (data, tools, methods).

TIMEPACs approach will consider:

Generating enhanced EPCs with BIM data

Creation of guidelines for EPC generation from BIM data with the goal of increasing the quality adn realibility of EPCs

Enhancing EPC schemas through operational data integration

Expanding the set of energy performance indicators in the EPC in a bid to highlight the holistic approach in the assessment of the building.

Creating Building Renovation Passports from data repositories

Creation of procedures to trace the evolution of building refurbishment using different sources such as BIM, EPC, technical building inspections, building materials, and operation data.

Integrating Smart Readiness Indicators and sustainability indicators in EPC

Creation of a methodology for SRI and environmental sustainability indicators integration in the existing EPC schemes according to effort for data collection and impact for indicators calculation

Large scale statistical analysis of EPC databases

Development of a large scale analyse methodology to determine the energy balance of the building stock, energy refurbishment scenarios and data quality checking of the EPC databases

Deployment

Verification scenarios

The five Transversal Deployment Scenarios will be validated in four verification scenarios across six European countries (Austria, Croatia, Cyprus, Italy, Slovenia and Spain).

In each scenario, it will be demonstrated to which extend the enhanced procedures contribute to improve reliability, effectiveness, user-friendliness, cost-effectiveness, etc. with regard to existing procedures in the participating countries.

  • Improving certification with enhanced EPCs
  • EPC exploitation through advanced analysis
  • Building renovation scenarios from the analysis of enhanced EPC data
  • Improving building operation with enhanced EPC

The project’s results will be used as training materials for certification professionals in Europe. Materials and courses for a variety of contexts will be available via an online platform.
