Implementation of on-site inspections
As part of the funding programme ‘Bundesförderung für effiziente Gebäude’ (Federal Funding for Efficient Buildings)
Topics: Energy efficiency, Funding, Buildings, Redesigning buildings and areas
Our mission: on-site inspections for quality assurance
With its on-site inspections, dena makes an important contribution to quality assurance in the Energy-efficient and Sustainable Construction and Refurbishment and Federal Funding for Efficient Buildings funding programmes. In this manner, dena supports the Federal Ministry of Economics and Energy, the KfW Group and the Federal Office of Economic Affairs and Export Control throughout Germany. dena has been carrying out on-site inspections for the Energy-efficient and Sustainable Construction and Refurbishment programme since 2013 and for the Federal Funding for Efficient Buildings programme since 2021.
The funding programmes promote energy-efficient buildings in refurbishment projects or new construction. dena sends experts on-site to ensure that the subsidised measures meet the requirements.
Our approach: implementation of random inspections of sites
dena has been tasked with the coordination, documentation, implementation and analysis of the on-site inspections. Once completed, the subsidised projects are randomly checked through on-site inspections. They are a component of the quality assurance of the funding programmes.
A typical on-site inspection is carried out in three steps:
- The funding recipients receive a letter from the KfW Group and the Federal Office of Economic Affairs and Export Control informing them of their inclusion in the spot-check with a request for further information.
- In the second step, independent energy efficiency experts commissioned by dena review the implementation status of the subsidised project on-site.
- Then dena processes these results and forwards them to the KfW Group and the Federal Office of Economic Affairs and Export Control. These organisations inform the building contractors of the results of the inspection.
Our milestones
- 2013–2026: Key findings from on-site inspections are incorporated into the further development of funding programmes and quality assurance measures. Information on common errors and difficulties is published.
- 2013–2024: The proportion of construction projects in which on-site inspections have identified deficiencies has declined over the years. This demonstrates the positive impact of the various quality assurance measures.
