Sports facilities

The typical sports facility problem

• Draughts are unacceptable: athletes are lightly dressed and air velocity is regulated.
• At 9–15 m tall with extensive glazing, the temperature is anything but even.
• Fresh air has to be supplied to code for every person in the building.
• Quiet matters: equipment noise must not drown out training or competition.

Recommended models

Requirement	Model
Fresh air plus climate control	OXA FK
Energy-efficient ventilation	OXA AR
Heating the hall	OXA D
Summer cooling	OXA K

Worked example

A 2,600 m² indoor arena, 11 m high, up to 250 people, at 30 m³/h per person → 7,500 m³/h of fresh air.

• OXA FK-2 — 3 units covering supply air, heating and cooling.
• Air velocity in the 2 m zone stays at or below 0.25 m/s thanks to the conical opening of the diffuser.
• CO₂-based control: air flow rises only with the number of people actually present.

The investor’s view: a venue with OPEX under control

For sports facilities, energy efficiency is not an abstraction — it sets the hourly hire rate and how far a municipal budget stretches. Warm-air heating for a high-ceilinged hall plus CO₂-driven ventilation gives you a running cost per hour of arena time that you can actually manage.

• Noise capped at 60 dB — training and competition without a background hum; the arena in the case study measured 52 dB.
• CO₂-driven ventilation: fresh air follows occupancy, so an empty arena is not heating the outdoors.
• One set of kit for winter and summer: the OXA-FK series covers heating, cooling and supply air — less equipment on the books.
• Life cycle: EBM-papst and Belimo components with servicing twice a season make costs predictable over 10 years and more.

Case study

A 2,600 m² indoor sports arena, 11 m high: 3 × OXA FK. Measured noise in the hall is 52 dB, there have been no complaints about draughts, and ventilation runs off CO₂ sensors.
