Kaisa Poikela and Jari Hannu are building their second house in Ritaharju. The two-story detached house, to be completed in September 2023, has been carefully designed based on the family’s previous experience. The construction and design process is a joint effort by the six-member family, and everyone has had a say in the outcome.

The rising electricity prices accelerated the Alajoki family’s, who live in a 200-square-metre detached house, plans to replace their electric heating system with district heating. Prior to replacing their heating system, their electricity consumption for domestic electricity and heating was over 30,000 kWh per year in a monitoring period of ten years.

Garam Masala Hall is a full-scale air dome owned by Oulun Jalkapallohalli Oy, located in Heinäpää Sports Center. The hall was completed in late 2020 and will significantly improve the conditions for winter football training in Oulu. The objective for the construction and maintenance of the hall has been to do it as responsibly as possible. This is also reflected in the energy choices made—the hall is heated with Oulun Energia's Onni - carbon-neutral district heating.

The Salo family’s heating substation had served their detached house bravely for 35 years. However, the substation’s retirement days were already at hand, as the estimated service life of a heating substation is approximately 20–25 years. Soon the Salo family heard a creak and bang from their hallway, when the old heat exchanger of the heating substation started to leak. This is when the Salos decided that it was time to replace the heating substation.

Senate Properties chose carbon-neutral district heating to achieve their own carbon neutrality targets. Senate has 20 sites in Oulu, which are now heated by Oulun Energia's carbon-neutral district heating - Onni.
