Energy performance certificates for multiple buildings – how to organise the data and process?

For multiple buildings, the main challenge is often not the calculations themselves, but collecting consistent and up-to-date data. We explain how to prepare a property register, standardise documentation, allocate responsibilities and deliver the work in waves. A well-organised repository supports not only the current certificates

Energy performance certificate vs building energy audit in Poland – what is the difference?

An energy performance certificate and a building energy audit may concern the same property, but they answer different questions. The certificate is primarily a formal description of the building’s energy performance, while the audit supports the assessment of measures and investment decisions. This comparison shows

What data and documents are needed to prepare an energy performance certificate for a large building?

For a large building, providing only the floor area and heating source is not enough to prepare a reliable energy performance certificate. Up-to-date data on geometry, building envelope, technical systems, use and modernisations are needed, while the required documentation depends on the complexity of the
