Experience-based knowledge centre on energy and buildings

The Danish Building and Property Agency will be a strong knowledge centre in public property administration and management of the public developer role. Building up of knowledge takes place through analyses, which are externally funded and which hang together with the overall strategy of the Danish Building and Property Agency.

The projects within knowledge building to be carried out in 2013 are:

  • an analysis of the experiences with energy renovation
  • an analysis of possibilities for optimising process energy
  • an analysis of possibilities for working with provisions of security in energy efficiency renovation projects.

Collection of experience

As part of the work with the government's energy efficiency renovation strategy, the Danish Building and Property Agency has received funds to conduct an analysis which is to assess before and after consumption with energy efficiency renovations and qualify conditions that promote and act as barriers respectively for energy efficiency renovations. The analysis will be conducted by external consultants.

Analysis of process energy

The Danish Building and Property Agency has already worked to reduce process energy consumption in fume cupboards. But there are many other technical installations, which result in great process energy consumption. As a part of the work in the energy efficiency renovation strategy, the Danish Building and Property Agency has received funds to conduct an analysis of the potential for reducing process energy consumption.

Guarantee of achieved energy savings targets

In connection with the Finance Act agreement for 2013, the Danish Building and Property Agency has been allocated DKK 2.5 million to develop and test new models for the implementation of energy savings with a guarantee obligation.

By far the vast majority of the energy efficiency renovations being carried out today take place without a guarantee that the conducted energy measures will actually result in the energy savings, which the contractors/advisors calculated before the start of the project. This trend has been known for a long time and has been confirmed by a new analysis conducted for the Danish Energy Agency and the Danish Building and Property Agency, which precisely points out significant discrepancies between the calculated and actually achieved savings.

In order to offset this, guarantee elements are used, especially in larger portfolios and long-term construction projects. Most prevalent are the ESCO and PPP models, where against payment, the supplier assumes the risk of achieving the planned energy savings. If the supplier does not achieve the promised savings, the supplier must cover the costs.

In order to ensure the developer's promised savings, the Danish Building and Property Agency is developing a number of guarantee models with the Danish Energy Agency, where contractors/advisors are held responsible for their promised savings. The guarantee models are not only to be directed at public building owners, but also be usable for cooperative associations/owner associations and private landlords. The models are designed as simple as possible, so that they are easy to use for the end-users.

Example of the PPP model

After the court reform in 2007, the courts and the Danish Building and Property Agency were facing an acute challenge in finding new premises. It was decided to build new court buildings in accordance with the PPP model, where the responsibility and risks, which are managed best by the PPP supplier and are normally the responsibility of the state as the developer in traditional project forms, are transferred to a PPP supplier.

The PPP supplier is responsible for the planning, construction of the building, compliance with the regulatory requirements, and etc. Additionally, the developer enters into a prolonged contract (typically 20-30 years), where the supplier is responsible for the operation and maintenance of the building. Together with the Danish Court Administration, the Danish Building and Property Agency prepared a detailed functional description of the requirements for the new court buildings. Here, an energy framework is established for example, which the PPP supplier guarantees to comply with throughout the contract period. 

PPP model works as intended

In spite of the fact that the buildings have not been in use for more than a year, the latest figures indicate that the energy frameworks will be complied with, which emphasises the strength of the PPP model. The PPP supplier has an incentive to comply with the contractual energy frameworks, if it does not want to have to pay a penalty for breach of the contract.

The positive difference between the calculated energy consumption and the current energy consumption is significantly more than expected for the court in Kolding, while the difference is also positive for the court in Herning. In both cases this can be traced back to the energy frameworks, which were established in the functional description.
