The renovation scheme closes the gap between the existing systems for certification of new and existing buildings. With the application of this system, buildings that have undergone renovation can now be certified. The requirements are based on those of new buildings, but also take into account the special features of renovation projects – the focus is on core renovation. In addition to ecological and economic aspects, user comfort plays an important role – for example in acoustic, thermal and visual terms, which has a major influence on the performance and motivation of workers.
In addition to office and administrative buildings, we would like other types of use to participate in the initial application phase. As with the new building systems, different applications of the renovation are also applicable:
The basis for the scheme Renovation, Version 2016 (SBV16) are the schemes for buildings, such as office and administration buildings, Version 2015. In other words, apart from a few criteria (including the tools provided) specially adapted for SBV16, the criteria (and tools) of Version NBV15 (currently only in German language) must be applied.
If the modernisation measures exceed the demarcation regulations for existing buildings, certification after renovation must be carried out. This is the case if the following modernisation measures were carried out in the last 3 years (either a or b):
a) 50 % of the facade and roof surface (energetically effective) + a significant change (generation and distribution) to ventilation, heating or cooling.
b) 25 % of the facade and roof surface (energetically effective) + two major changes (generation and distribution) to ventilation, heating or cooling.
Renovated buildings with mixed-use can also be submitted for certification. The usual demarcation regulations for mixed-use from new construction are to be applied.
As with the existing new construction certificates, the awards will include platinum, gold and silver.
Since "renovation" is very similar in content to the schemes of the 2015 Version (german), the audit can be carried out by all trained DGNB auditors for buildings.
All documents relevant to the audit are available on request from René Traunspurger firstname.lastname@example.org.
The project registration for the pilot phase of the scheme "renovation of office and administration buildings" has been open since May 2016.
At present, we can provide you with the criteria and tools for the scheme "renovation of office and administration buildings", Version 2016 is within the scope of the pilot phase. However, the system can be easily transferred to other types of use. We will be happy to create tools for you on request.
The DGNB Scheme for existing buildings is based on the actual use of the property being evaluated. This simplifies the documentation process considerably compared to the certification of new construction projects. The certificate for existing buildings remains valid for three years, and re-certification is a simple process.
An economically efficient building operation with focussed investment planning is only possible, if transparent data for the building is available. DGNB Certification provides the information and data needed for a sustainable optimisation strategy.
In order to ensure that older buildings can also benefit from a DGNB certificate for existing buildings, the following rules apply to the application of the individual schemes:
For existing buildings, there is also the option of seeking a pre-certificate before obtaining the full certificate. It allows for estimated values to be given for the criteria that are influenced by, for example, modernisation measures. The pre-certificate is valid for 18 months. In order to obtain a full certificate, only the estimated values need to be verified in the course of certification. The values that have already been verified in the course of the pre-certificate do not need to be verified again. The full certificate is valid for three years.
The main differences to the certification of new constructions are:
The criteria for renovation projects or existing buildings are currently only available in German. If you have any questions our certification team will be happy to provide you with information.
