DGNB certification of commercial property

Hirschsprung Hus, located at Bredevej 2 in Virum, North Zealand, was originally constructed as a tobacco factory in 1951. Since then, the property has been extended, and served as a domicile building until 2011, when it was converted into a multi-user building. Hirschsprung Hus currently comprises six leases, with a total area of 17,500 sq.m.

Situation

PKA focuses on continuously improving the properties in their portfolio, so that the properties fulfil future requirements and continue to be attractive leases. PKA therefore wished to utilise the considerable potential to optimise Hirschsprung Hus by investing in an improved indoor climate and lower energy consumption, in conjunction with a conversion of the property in 2011.

In order to visualise and concretise the high standard and degree of sustainability of the property, PKA wished to DGNB-certify the property under the "properties in operation" certificate.

Problem

To achieve DGNB certification, the building must be evaluated on the basis of a number of criteria within the five main areas in DGNB: environmental quality, economic quality, social quality, technical quality and process quality. The areas must be validated individually and must all achieve sufficient points for the overall property to be certified.

At the time of certification, Green Building Council Denmark was still developing a pilot project, and the certification manual had not yet been finalised.

Solution

Certification / auditing Energy consulting

DEAS performed the certification work which included gathering documentation concerning the property within a large number of areas, including environmental impact, finances, condition of the climate screen, indoor climate and flexibility.

In conjunction with the pilot project for Green Building Council Denmark, DEAS occupied a consultant role in testing the pilot manual, optimizing it, and testing the manual on Hirschsprung Hus. The role included handling calculations, data collection and certification of the property.

Result

In December 2016, Hirschsprung Hus achieved gold certification in the sustainability class under the DGNB certification scheme. Certification was granted on the basis of a number of green solutions, such as the installation of LED lighting and reduction of heat impact from windows. The solutions ensure low energy consumption, reduce climate impact and create a pleasant indoor climate for the benefit of the tenants.

The effects were shown by the audit through the documentation and calculation of the collected data. 

This certification means that Hirschsprung Hus now commands a stronger position in the competition with other commercially leased properties when vacant premises arise. PKA has achieved clear evidence of the building's sustainability and documentation that the property is attractive to current and future tenants. They have also achieved even greater and more detailed insights into the property.

In conjunction with the DGNB certification, DEAS energy engineer Lotte Krusegaard was also nominated as auditor within the category "properties in operation".

Two stages to certification

DEAS offers certification of properties in operation. The process has two stages. 

  • Stage 1: We screen properties to identify whether they are suitable for DGNB certification. Their status and areas of improvement are studied in order to achieve an overview of the improvements necessary to achieve certification.
  • Stage 2: If the screening result is positive and certification is realistic, we can make the investments required to achieve certification in a specific class. We then undertake the actual certification.
