• Funded by the Nordic Council of
Ministers
• Nordic energy agencies joint
project 2015-2018 to be continued
• Goal: Develop a software platform
for MV&E using web crawler data
Nordcrawl – a Nordic project to explore
webcrawler as a tool for product policy
development and market surveillance
2019-03-13 5
A sophisticated tool for cleaning, sorting,
linking and analysing crawled data
1. Data on products,
stored at various publicly available web sites.
2. The web crawler engine and a temporary raw data storage.
3. A product data base containing processed data.

Allowing focusing on risk
• Finds retailer product pages where the energy
label is missing
• Extracts energy label image-link/image-
element
• Analyse => missing label or not

Policy evaluation:
Impact assessment of
MEPS and labelling
(Near)future developments
• Create module for ex-post evaluation of impact of ecodesign and
labelling, incl. market response to change in legislation
• Extend product coverage
• More sophisticated algorithms to identify non-compliance
• Refine the estimation of sales
• Integrate with the Database “European Product Registration for
Energy Labelling”
