Energy Saving Light changes across Campus

As part of Reaseheath College’s commitment to improving environmental sustainability the Estates team have been making changes to the lighting over several years and in fact are now in the second generation of changing light bulbs and fittings to be more economical in their usage.

In all new build projects and refurbishments, the College now use lower energy LED lights instead of the old style incandescent or halogen high-energy light bulbs.  LED bulbs and fittings have reduced energy running costs and are designed to last 20-50 times longer than traditional incandescent lamps, the potential savings associated with them can be huge.

As a general rule, LED light bulbs use around 10% of the energy of incandescent light bulbs, as indicated by their equivalent wattages.

Additionally, lights are replaced in areas where the College thinks significant savings in electricity usage could be made such as – Equine arena, Construction works shops, Engineering workshops, REAA building, the farm sheds and also the external street and building lights.

Below are examples of how the college has reduced energy consumption by exchanging light bulbs

 

FARM

	Location
	Robotic Milking	Data Centre Lely
Existing	1500W	1260W
New	960W	708W

So the farm has seen a 36% reduction in energy use in the Robotic Milking area and a 43.8% reduction in the Data Lely Centre.

 

EQUINE ARENA LIGHTS

 

EXISTING LIGHTS AVERAGE COSTS 

EXISTING LIGHTS	POWER	QUANTITY	HOURS PER WEEK	DAYS PER WEEK	WEEKS PER YEAR	ANNUAL HOURS	ANNUAL KwH
LOW BAY	400W	42	8	5	50	2000	33,600

 

NEW LED LIGHTS AVERAGE COSTS 

NEW LIGHTS	POWER	QUANTITY	HOURS PER DAY	DAYS PER WEEK	WEEKS PER YEAR	ANNUAL HOURS	ANNUAL KwH
LED	156W	42	8	5	50	2000	13,104

 

The lighting in the Equine arena energy usage has been reduced by a huge 61%.
