In 2008, PKA decided to work actively to create properties with a healthy indoor climate, social qualities and a low climate impact. Towards 2020, PKA will reduce the portfolio’s climate impact by almost two thirds.
The average CO2 burden in 2008 was around 25 kg/sq.m. and the energy efficiency of the entire portfolio was 122 kWh/sq.m. On average, the properties had a D energy label.
To plan and execute a targeted campaign, a detailed overview of the properties in the portfolio was needed, in order to set optimum priorities for the action taken.
Furthermore, the projects would be executed as profitable energy-saving investments, as part of the general operation and maintenance, in cooperation and close dialogue with both residential and commercial tenants.
High demands were also made of the subsequent documentation of the energy-saving activities, in order to assess the actual effects.

Operation and maintenance
In collaboration with PKA, for all properties larger than 1,000 sq.m., full coverage with central energy management via Min Energi was established.
To ensure a detailed overview of the portfolio’s energy consumption, a database of existing energy labels, with dates, was created. The database is kept continuously updated.
For larger initiatives, such as roof, window and installation projects, the building dossiers are screened for potential energy savings. Energy savings are also incorporated in the ten-year operational and maintenance plans for the properties, so that energy efficiency is included and documented whenever measures are implemented.
On the basis of a reasonable distribution of financing between PKA and the tenants, there is dialogue with tenants on the establishment of joint projects to promote both indoor-climate improvements and energy efficiency in the properties.
In cooperation with DEAS’ energy partner, Ørsted, supplementary financing is available for all energy-saving projects.
DEAS is in ongoing close dialogue with PKA, including quarterly status meetings, just as DEAS annually documents energy savings data, among other things from energy management and changes in the properties’ energy labels.
During the first phase of the energy improvement measures in 2008-2015, the average annual CO2 load was reduced from 25 kg/sq.m. to 15 kg/sq.m., equivalent to a CO2 reduction of 40%.
The energy efficiency of the portfolio was improved from 122 kWh/sq.m. in 2008 to 113 kWh/sq.m. in 2015.
Moreover, the properties in the portfolio have improved from average energy label D to C, and the number of energy labels poorer than D was reduced to less than 30, equivalent to an area of less than 10% of the portfolio.
Continuous status reporting ensures that PKA achieves insight into and an overview of the energy efficiency improvements and that continued progress is made.
Goals for 2020: PKA has chosen to prolong and set ambitious new climate goals for the property portfolio, and is therefore continuing this extensive work as part of the company's sustainability strategy.
The goals for 2020 include, on average, for the portfolio:
- Further reduction of CO2 load to 8 kg/sq.m. in 2020.
- Improvement in energy efficiency to 85 kWh/sq.m. in 2020.
- Improvement in average energy labelling from C to B.
