Sub Air System
Bro Hof’s greens will open earlier and close later in the season than at other Stockholm clubs. This is possible thanks to a system of flat drainage pipes below the greens, making it possible to heat, cool and dry the ground.
This very modern construction is not used anywhere else in this configuration. Bro Hof has three mobile herring-bone style subterranean pipe systems, connected to one surface drain per green. These can be used to either introduce oxygen or warm air to heat the greens, thereby making them ready earlier in the spring and extending the season in the autumn. At Augusta the pipes are used to cool the greens in the heat… but the pipes can also suck up water to dry out saturated greens.
