BACKGROUND
After the village of Denholm in the Scottish borders lost its previous primary school to a fire, the Scottish Borders Council set out upon a visionary journey to create a simply wonderful and environmentally mindful replacement.
ECOLOGICAL
Architect Ray Cherry of the Scottish Borders Council has devised a replacement scheme very much in keeping with the local area. The new build school incorporates the latest, proven ecological technology from ground source heat pumps and solar panels to the Greyflow® fire sprinkler system.
The Greyflow® fire sprinkler system makes use of harvested rainwater within its design. From an environmental standpoint, harvested water is becoming increasingly important in new build schemes, and it is estimated that only 9% of the water used at school need be of drinking water quality.
GREYFLOW® FIRE SPRINKLER SYSTEM
The council architects elected to incorporate a Homesafe Greyflow® fire sprinkler system as part of its ecological remit. There is less reliance on mains water as rainwater is collected from the roof and is filtered prior to being stored in an underground tank.
This water serves both the toilets and the sprinklers. The sprinkler pipe work provides the distribution network for the rainwater harvested toilets. In turn, the toilets at the end of each sprinkler line serve to check the system is live and also guard against water stagnation.
Altogether, the sustainable Greyflow® fire sprinkler system is generally a more self-sufficient, more cost-effective and more reliable option.
MAINTENANCE
At hand-over, all the staff at the school benefited from an explanatory talk on their Greyflow® fire sprinkler system. The pumps are being run and tested on a daily basis and the water in the system is continually moved and refreshed.
The system is maintained once a year under contract, with free call-out. Additionally, the filters are checked and cleaned twice a year. All attending Homesafe engineers have been CRB checked.
