Environmental impact assessment of nearly zero energy building

The European Commission’s Energy Performance of Buildings directive requires all new buildings to be nearly zero-energy according to the given time frame. The ministry of environment is responsible for the preparation of the nearly zero energy building (nZEB) legislation. During the preparation an impact assessment of the legislation is also done. In this project the environmental impacts of the nZEB proposal are considered and analysed. The main changes in the forthcoming legislation are related to energy efficiency requirements for the new buildings.

  • Requirements for the energy efficiency rate (E-value)

  • Energy balance calculations (for instance, the inclusion of renewable energy in E-value calculations)

The project had two aims:

  • Look into the main environmental impacts of the nZEB legislation proposal. The main focus is on energy consumption and the related greenhouse gas emissions and primary fine particles in the time span from 2020 until 2030 and even until 2050.

  • Consider and compare the impacts of different requirement and energy balance options on the emissions.
