Södra Climate Arena in Växjö

The requirements for this elaborate sports hall in Vaxjö in Sweden was very demanding: compact wooden structure, all‐glazed southern facade, four tennis courts, height 9,0m to the north. The building had to have a two‐story section to the south with reception, café, conference room, fitness, locker room, and technical facilities. The floor area of 3,600 m² and completed by 2012.

Excellent presentation in English about the Södra Climate Arena in Växjö presented at the Passive House Conference in Hanover in 2016 by Simone Kreutzer describing the technical details about the building structure and building system.

The building is equipped with ventilation system compromising of 2 air handling units with high maximum air volumes (1 600 l/s and 1 300 l/s) with rotating heat exchanger certified for passive houses and preheating and cooling with four boreholes. Tennis hall unit recirculates air from tennis courts. All air handling is demand-controlled (humidity controlled in the shower area, CO2 controlled in conference rooms, CO2 and temperature controlled in the hall). Heating is provided by district heating.

This report presents measurements of energy consumption during one year of operation (September 2013 – August 2014) as well as evaluation of the tenant’s experience and the operating technician’s observations in the building.

The measured values are not typical year corrected but correspond to the actual readings. To remove emissions from new material and new furniture, it has been decided to ventilate the building a little more during the first year of operation. Therefore the follow-up to year two was expected.

Report by Joakim Norén and Oskar Räftegård from 2015.

Temperatures and relative humidity have been recorded at various locations in the hall over two years. Purchased district heating and electricity during the period was based on data from charging meters obtained from the energy supplier. The project also studies how the occupancy of the hall affects the climate’s variation over the day. The measurements show that the environment in the hall at the tennis courts is even. After adjusting the heating system in December 2012, the temperature has been at a minimum of 17.4 ° C in winter and a maximum of 22.6 ° C in summer. The measurements also show that there is a clear correlation between the temperature diurnal variation and the number of tennis courts booked. Need for purchased energy is low, especially district heating. The building uses about 40 kWh / m2Atemp, year electricity and about 13 kWh / m2Atemp, year district heating. District heating demand in addition to baseload is mainly due to the outdoor temperature, while electricity use depends on both use (number of courses booked) and outdoor temperature.
