EPC data quality

description: The present deliverable, D1.3, relates to the work performed in Task 1.3 of TIMEPAC. Task 1.3 is part of Work Package 1 (WP1), which is aimed at carrying out a comparative study of the elements involved in the energy performance certification (EPC) data flow devised in TIMEPAC, i.e., generation, storage, analysis and exploitation. Work Package 1 concerns the context analysis that supports the EPC workflow; it allows to identify potential improvements, vulnerabilities, threats and risks related to the upgrade of the already existing energy performance certification schemes. Task 1.3 focuses on one of the EPC data flow elements, namely the EPC data analysis. In this task, deficiencies and potential improvements of current EPC data quality across participating countries are identified.


On the national/regional level, the TIMEPAC partners analysed and compared the EPC data − in terms of input and output data − and collected the necessary information to analyse the input data quality, in terms of data sources and ways of data determination. Information on the existing certification tools and/or protocols to validate the EPC data is provided, as well as the current procedures, methods, instruments that detect essential data quality issues in the participating countries/regions (i.e., Austria-Province of Salzburg, Croatia, Cyprus, Italy-Regione Piemonte, Slovenia, Spain-Catalonia).


A methodology was followed to collect and compare data between the involved countries/regions, based on the use of a data collection sheet and comparison tables. The data collection sheet was structured in such a way to gather information from partners through a bottom-up approach that follows a comprehensive collection of the available data.


The comparison tables were suitable to compare the information provided by the participating countries/regions (cross-country comparison) on the following research topics: “EPC data availability”, “Data source and determination”, “Input accuracy”, and “Overview of applications”. The tables are interrelated, i.e., the information coming from a table affects or is related to the subsequent one. In addition, the starting point (“EPC data availability”) and the ending point (“Overview of applications”) are strictly related to the elements of the EPC data flow placed just before and after the EPC data analysis, i.e., the EPC storage and the EPC exploitation, respectively.


The outcomes of the context analysis on the EPC data quality and availability inform the Transversal Deployment Scenarios (TDSs) of TIMEPAC that are aimed at developing and delivering new methods to implement enhanced EPC schemas in WP2. The potential improvements outlined in Task 1.3 and the related TDSs are listed as follows:



	
To expand the set of energy performance (EP) indicators in the EPC (operational data, costs, IEQ aspects, etc.) (TDS 2),
	
To integrate the Smart Readiness Indicator (SRI) in the EPC (TDS 4),
	
To create guidelines for EPC generation from Building Information Modelling (BIM) data (TDS 1),
	
To enhance EPC with information from inspection of technical building systems and other building related data (TDS 3),
	
To foster the generation of EPCs from BIM models (TDS 1),
	
To improve the accuracy and reproducibility of the whole EP assessment procedures (TDS 2),
	
To check quality of the EPC data (TDS 5),
	
To generate Building Renovation Passport (BRP) from EPC data (TDS 3),
	
To exploit the EPC for carrying out energy balances of the building stocks (TDS 5).
