Data on nearly zero energy buildings (NZEBs) projects and best practices in Europe

Abstract

This data article refers to the paper “Assessing Nearly zero energy buildings (NZEBs) development in Europe” [1]. Data linked with this article relate to collected best practices NZEBs throughout Europe. Data on building geometry, year of construction or renovation, primary energy consumption, saving percentages, renewable production, heating demand are provided.Data allow an overview of the status of most commonly implemented efficiency measures and renewables in NZEBs. In particular, data are available in relation technologies, such as heating, domestic hot water, lighting, renewable sources, ventilation, cooling. Heat recovery efficiency data are also collected. U-values are detailed for roofs, walls, floors, windows. Further data can be visualized in relation to technologies costs, cost of construction and maintenance.
