Implementing nearly Zero-Energy Buildings in Poland, Romania, Bulgaria

Towards a national definition and roadmap

Published: 20/11/2012

European legislation on buildings and energy efficiency requires European Member States to develop strategies on how to progressively transform their national building stocks into an energy performing and climate neutral built environment. As of 2021, 'nearly Zero-Energy Buildings' will become mandatory for all new constructions. To facilitate this process and to demonstrate the technical and economic feasibility of the nearly zero-energy standard, BPIE commissioned Ecofys and local experts to undertake a technical and economic analysis of the situation in three Central and Eastern EU countries - Poland, Romania and Bulgaria - and developed holistic implementation plan for each.

The studies build on the previous BPIE report Principles for nearly Zero-Energy Buildings and evaluate through simulations whether and how the general assumptions can be transferred to the local situation in Romania, Poland and Bulgaria. Different technological solutions - using variants of improved thermal insulation, energy efficient equipment for heating, cooling, ventilation and hot water and considering renewable energy generation - were examined to develop different specific nationally adapted nZEB solutions for residential- and non-residential buildingsFor costs assumptions of the economical evaluations theactual situations at the construction and energy sectors in the countries have been considered.  Based on the simulation results, the study proposesconcrete national solutions for nZEB for the defined building categories, as well as policy implementation roadmaps towards 2020.
