Step 3 – Following up

This phase consist of the following up the effect of the action package after it has been implemented. The energy use during at least one year after renovations is compared to the energy use before implementation of the action package. Profitability results are checked based on the figures from the measured energy use and the approved final costs for the action package are used.

Stage 3 is divided into the following tasks:

• Measuring energy use
• Checking profitability results

To ensure that the use of energy in a building can be followed up afterwards a plan for measurement and follow-up is formed already in Step 2 (sometimes already in Step 1). This means that installation of extra meters and measurement system needed for measuring electricity and heat energy use will be included to the design and tendering documents.
