Buildings data and tools

BPIE contributes, and has contributed, to the development of several tools within the framework of EU-funded projects and more.

Database of grey-box model parameter values for EU building typologies

The database developed by the Horizon 2020 project AmBIENCe collects information and data on the parameters needed for both the Energy System Impact Assessment and the creation of performance models. The database provides information about the building stock segments’ reference building, as well as information on the building stock segments themselves.


Ground breaking tool measures energy savings across portfolios of buildings, which could be used to replace inaccurate ‘deemed’ estimates of energy savings, creating a foundation for energy companies to contract for energy savings instead of fossil fuels.

HotMaps Building Stock Analysis

The data collected in the building stock analysis are used as starting point to calculate the useful energy demand (UED) for space heating (SH), space cooling (SC), and domestic hot water (DHW) for each EU28 MS down to its local level.

EUCalc Transition Pathways Explorer

The EUCalc Transition Pathways Explorer allows you to run your own emission scenarios, powered by the EUCalc model, and directly visualise its effects. Based on the ambition level you choose for each sector, the EUCalc model projects the energy and material use, greenhouse gas emissions and the consequent societal, environmental and land use impacts.

ExcEED platform

The ExcEED project -which stands for European Energy Efficient building district Database: from data to information to knowledge – takes the pulse of the actual energy consumed by last generation of buildings.

The EEFIG DEEP Platform

The EEFIG DEEP platform is an open-source initiative to up-scale energy efficiency investments in Europe through the improved sharing and transparent analysis of existing projects in buildings and industry.


ENERFUND is a tool that rates and scores deep renovation opportunities and enhances public awareness in building retrofit potential.

HRE Thermal Atlas

The model is a geographic representation of heating and cooling demands in the 14 countries, excess heat potentials, prospective district heating networks, availability of renewable energy resources such as geothermal, solar irradiation, biomass and more.

FROnT consumer tools

The tools provide both support on cost estimation of renewable energy technologies and on decision making about installing and replacing parts of heating and cooling systems.


MURE (Mesures d'Utilisation Rationnelle de l'Energie) provides information on energy efficiency policies and measures that have been carried out in the Member States of the European Union. The information is accessible by query in the database. The distribution of measure by type can be visualized through radar graph.

IEA Policies & Measures Database

The IEA’s Policies and Measures Database provides access to information on past, existing or planned government policies and measures to reduce greenhouse gas emissions, improve energy efficiency and support the development and deployment of renewables and other clean energy technologies.

GBPN Policy Comparative Tool

What are the main components needed to develop ambitious and dynamic building codes and supporting packages? Experiment with this tool to find the combination of elements that can help move the building stock in your region towards zero energy.


Eurostat is the statistical office of the European Union situated in Luxembourg. Eurostat offers a whole range of important and interesting data that governments, businesses, the education sector, journalists and the public can use for their work and daily life.


The TABULA WebTool has been developed within the framework of the Intelligent Energy Europe projects TABULA and EPISCOPE. The objective is to disseminate the general idea of national residential building typologies to building experts from European countries.


BuildingRating is an online hub for building energy and water benchmarking policies. It provides useful tools and resources that shed light on building performance in jurisdictions throughout the world.

ENTRANZE Online Scenarios

This tool provides the results of alternative scenarios of development of the building stock and its energy demand in the EU-28 up to 2030.


This tool, developed in the framework of the H2020 project ENTRANZE, provides an in-depth analysis of the structure and dynamics of buildings and related energy systems in the EU.

CommONEnergy Data Mapper & Scenario Tool

The data mapper is an online tool which represents a quick, easy and tailor-made access of national and comparative international indicators on the commercial building stock.

CommONEnergy Integrated Design Process

The tool provides designers, owners and managers relevant information to start a shopping centre retrofitting process. It collects information about malls’ archetypes and specific technology features, as well as climate, social and urban contexts.

CommONEnergy Economic Assessment Tool

Developed under the CommONEnergy project, the Economic Assessment Tool is a convenient and useful instrument to estimate the energy saving potential and economic benefits of retrofitting of shopping malls.

ZEBRA2020 Scenario Mapper

This tool shows scenarios of the market transition to nZEB (nearly Zero Energy Buildings). It analyses how current building standards and other policy settings affect the building stock transition and corresponding energy demand targets of the building sector until 2050 and how more ambitious policies could change this transition.

ZEBRA2020 Data Tool

Developed in the framework of the EU funded project ZEBRA2020, this tool shows energy efficiency trends in buildings and display information on nZEB buildings.
