Introduction - Questionnaire on the usage of data from the EPC-procedure

Logo Project EPC4SES

The EPC4SES project aims to use data from the creation of energy performance certificates for the creation of digital twins. EPC4SES Partners represent five countries – Austria, Germany, Norway, and Spain. Our flyer may be downloaded here

The questionnaire is structured into the application segment regional planning heat, one part for the the operation of heat related applications, and one for the application field power, which might be filled in alone.

tablet application

Digital twins use the building component characteristics, eventually measured values like meters or wall temperatures or assumed user behaviour to predict the energy demand of buildings. Thus data acquired during the process of getting the energy label is used saving energy or allowing use of renewable energy, when dimensioning the energy system or operating it.

In the following questionnaire we would like to ask you to help us to evaluate applications for digital twins and to find new ones that will work with data from the energy labeling process. But the building data may also be used for strategic decison taking, involving the erection of networks or the regional planning for renewable energy.

The project has taken up speed, also since new papers already include EPC as data source.

Within the project EPC4SES, we would like to know about your situation and expectation, before specifying tools for supporting the use of EPC data for digital twins of buildings.

If you want giving feed-back on a tool which is allowing to calculate the energy efficiency and allows us to use the building data, please visit this Link (in German only) Thank you.

Data protection and data security

Do not enter person related or relatable data. The server-generated information about the browsing client is stored, but the IP-address truncated to make data anonymous. Data is stored in a password protected database at the server of the ISP using SSL-secured upload. Usage of the aggregated data is made only for the ERANet REGSyS project, individual answers are published anonymously only.

Application Field Heat Regional Planning

This application simulates the energy demand over the year. Sensor data are not necessary for this. Depending on the application, annual totals are the result of the simulation.

1 : What applications do you see for digital twins of buildings?

You might select more than one item...

Analysis of the current or potential regional climate friendliness in the field of building energy
Investigation of the possibility of energy-autonomous regional cells
Preliminary planning the shift to renewable energy
Checking feasibility of new types of cooling/heating networks (low temperature, three pipes etc.)
Any other applications which you favour, please describe below

1a : Any other application that comes to your mind for regional energy planning?

2 : The authorities or subcontractors commissioned by them can access the data of the housing and building registers, where (for example in Austria) certain energy relevant information is also stored. Regionally there are databases for this purpose, which contain even more detailed data. Furthermore, 3D GIS (CityGML) data can be used. Do you see a possibility to connect both data sources, EPC databases and 3D GIS data?

  Yes
  Rather Yes
  Rather No
  No
  Don't know
