First results from the TIMEPAC survey

- Published the

The TIMEPAC project is dedicated to supporting Europe’s decarbonisation goals, as established in the European Green Deal. As part of this effort, the project has launched a survey titled “GETTING READY FOR THE BUILDING RENOVATION WAVE,” and invites building experts to participate. The survey aims to identify any obstacles or barriers that may arise during the implementation of new Energy Performance Certificates in accordance with the revised Energy Performance of Buildings Directive (EPBD).

By taking the 10-minute survey, building experts can contribute to the development of the next generation of building certification tools, methods, and training required to support the renovation of Europe’s building stock. These new tools and methods will be available through the TIMEPAC Academy, which will be launched in the near future.

Join us in our mission to decarbonize Europe’s building stock!

Profiles of survey responders

As of May 2023, around 1,400 building experts have participated in the TIMEPAC survey thus far. The majority of the data collected comes from countries where  the TIMEPAC enhanced energy performance certification procedures will be tested: Austria, Croatia, Cyprus, Italy, Slovenia and Spain. Nevertheless, the survey is open to building experts from all EU countries involved in the renovation of the building stock.

Figure 1 Profiles of survey responders

As can be seen from Figure 1, the majority of respondents are professionals in building sector, including architects and engineers, professional certifiers, and energy auditors.

Current knowldge of building perfomance assessment tools and methods

We have analyzed the current level of knowledge of building experts from Austria, Slovenia, Croatia, Italy, and Spain in relation to the Smart Readiness Indicator (SRI), Building Renovation Passport (BRP), Building Information Modelling (BIM), and Level(s).

Figure 2 Current knowledge of building evaluation tools and methods

Overall, as can be seen in Figure 2, BIM is a well-known concept among building experts from all participating countries, whereas Smart Readiness Indicator (SRI), Building Renovation Passport (BRP), and Level(s) still appear to be unfamiliar to many actors involved in the building sector.

A more detailed reading shows that respondands in Austria have the most knowledge of building renovation passports, while respondents from Slovenia appear to have more knowledge of SRI and Level(s). In Croatia and Italy, knowledge of SRI, BRP, and Level(s) is relatively low. Participants from Spain have amonsgst the highest knowledge of BIM but also the least knowledge of SRI and maintain an above-average knowledge of Level(s) compared to the other countries.

Areas of needed support

Figure 3 Areas of needed support and training

Overall, while most countries and respondants are familiar with BIM, it is also an area where most support is requested to deepend this knowledge further in order to use it for energy performance assessment and certification. Many respondents would also like further support to understand building smartness assessments and building renovations passport procedures.

The upcoming TIMEPAC Academy will provide know-how that can help building experts acquire the necessary skills and knowledge to meet their needs. We encourage building experts from all EU countries seeking to renovate their building stock to participate in the TIMEPAC survey and benefit from the resources that the TIMEPAC Academy will offer. Your contribution is invaluable and will help us shape the future of building certification tools, methods, and training to support the decarbonization of Europe’s building sector. We would like to thank everyone who has participated in the survey so far, and we look forward to receiving more responses from across the EU. Together, we can make a meaningful impact towards a decarbonized building sector.


Building Information Modeling (BIM)

Building Information Modeling (BIM) – is a process supported by various tools, technologies and contracts involving the generation and management of digital representations of physical and functional characteristics of places. Building information models (BIMs) are computer files (often but not always in proprietary formats and containing proprietary data) which can be extracted, exchanged or networked to support decision-making regarding a built asset

Building Renovation Passport (BRP)

Building Renovation Passport (BRP) – consists of a roadmap indicating a sequence of renovation steps over several years instead in one go, with the objective to transform the building into a zero-emission building by 2050. It shall indicate the benefits in terms of energy savings, cost savings, greenhouse emission reductions as well as broader benefits (on health, comfort, resilience to climate change).

Smart Readiness Indicator (SRI)

Smart Readiness Indicator (SRI) – is used, a new indicator that assesses the technological readiness of buildings, interacts with their occupants, co-operates with connected energy grids and operates more efficiently


Level(s) – provides a common language for assessing and reporting on the sustainability performance of buildings. It is a simple entry point for applying circular economy principles in our built environment. Level(s) offers an extensively tested system for measuring and supporting improvements, from design to end of life. It can be applied to residential buildings or offices.
