CT1 New Nearly Zero Energy Buildings

CT1 supports the delivery of public new Nearly-Zero Energy Buildings (NZEBs), starting from the 2018-target and moving beyond current levels. Member States must implement NZEB requirements for new construction. Implementation for public buildings has started at the end of 2018 and will be a mandatory requirement for all new buildings by the end of 2020. The work under this Team will examine both energy efficiency aspects as well as the use of renewable energy in new buildings.

CT1 focuses on large and complex buildings and a special part is dedicated to public buildings. This work is closely linked to CT2 – Building Codes and many activities will be deployed as collaboration between the two teams. Specific attention will be given to definitions of NZEBs, definitions of nearby renewable energy sources and on how cost-optimality is implemented in the form of requirements for new buildings. Ventilation and indoor air quality will be an important element in the work with NZEBs.

This Core Team leads work and reports progress on the following articles of the EPBD:
• Article 2 – supporting the national application of the definition of NZEB
• Article 6 on “New Buildings”
• Article 9 on “Nearly zero-energy buildings”.

This includes application of the definitions, development of National Action Plans, and reporting progress in increasing the number of NZEBs.

The Core Team further supports work on development of calculation methodologies and cost-optimality for new buildings (Articles 3 and 5, and Annexes I and III), electro-mobility (Article 8a), certification of and finance for new buildings (Articles 10 and 11).

CT1 supports all articles and elements relevant for NZEB buildings. The key topics for CT1 include:
• Further development of the definition of Nearly-Zero Energy Buildings.
• Nearly-Zero Energy public Buildings from 2019.
• National action plans for NZEBs.
• Levels of Renewable Energy, nearby systems.
• Reporting on NZEB development.
• NZEB development beyond 2021.
