Rooftop gardens are ideal for aquaponics. Harnessing the power of the sun can completely close the aquaponics loop, negating the necessity to use grow lamps. Here at Aquaponics NU we are utilizing highly-efficient LED grow lamps, that significantly reduces energy inputs, but where there is an opportunity to utilize rooftops, we always take it.
Spatially speaking, rooftops are ideal as they are a conventionally underutilized surface. By growing vegetables on rooftops we can also reduce heating and/or cooling expenses as the biomass creates a valuable insulating quality.
Aquaponics NU has experience in utilizing rooftops for agricultural ventures, starting with the roof of their office at Bryggen 93.
