Project activities

Key activities of the RePublic_ZEB project include:

Analysis of the public building stock and definition of reference buildings

Data collection and analysis of energy consumption for the public building stock in each target country, including heating, Domestic Hot Water (DHW), cooling and lighting. This analysis is closely linked to the RePublic_ZEB goals and will mainly use data from IEA, IEE and EASME, previously known as EACI (e.g. DATAMINE). The national data analysis conducted will enable a cross-country comparison in order to produce energy performance benchmarks for various types of public buildings, based on use, size and operation. These reference buildings will be used as prototypes to develop a range of standard cost effective measures (“packages of measures”). This will allow partners to draw up a target group of public buildings, to be used as case studies, in order to assess the impact of adopting a mix of measures during renovation and / or refurbishment.

Coordinated by: Black Sea Energy Research Centre (BSERC)



Assessment of the status quo and analysis of opportunities for refurbishing public buildings towards nZEB

This activity will identify the most suitable building technologies available on the market to reach the nZEB target for the public building stock. An analysis of the existing regulatory frameworks will look at identifying barriers, drivers and current best practice, as well as integrate results of previous EU projects (e.g. ENTRANZE, Annex 52 and Annex 53). In order to create a valid set of interventions, input and cooperation from industry professionals will be required. The most suitable building systems and technologies will be organized into “packages of measures" which will be further analysed in the next activity.

Costs/benefits analysis of the “packages of measures” for the refurbishment towards nZEB

This activity will assess the reference buildings and “packages of measures", in view of their energy and cost saving potential. Each partner is responsible for defining and applying the most appropriate methods and tools to determine the fossil fuel and renewable energy requirements and associated costs for each “package of measures”. The overall aim is to increase confidence within the construction industry and offer a user friendly tool to select the most suitable and cost optimal technologies. Being able to clearly demonstrate saving potentials should enable and encourage builders to promote nZEB refurbishment processes to public building owners.

A cross-country comparison will be conducted to identify any uncertainties and allow a sensitivity analysis to be completed. As part of testing the results a review of previous EU projects (e.g. Annex 52 and Annex 56) and studies (BPIE: Implementing the cost-optimal methodology) will also be completed.

Coordinated by: Politecnico di Torino (POLITO)



Strategies and guidelines towards nZEBs

This activity focuses on promoting and developing guidelines to accelerate the refurbishment of the public building stock towards nZEB standards. The target audience for these best practice guidelines includes the construction industry, housing organizations, owners of large building stock and developers. The promotion activities will be accompanied by a set of policy recommendations to facilitate the implementation of nZEB standards in each country. The proposed nZEB definitions and roadmaps will be developed in conjunction with the respective policy makers. Adopting a bottom-up approach will support the practical implementation of nZEB renovation initiatives and result in measurable results.

Communication and dissemination

The dissemination activities will facilitate the circulation of information and the exchange of options and ideas between partners in order to assist the projects’ strategic planning. The overall aim is to increase the visibility of the project results on a local, national and European level through a series of targeted dissemination actions.
