Energy Saving Case Studies Using LED Lights

Hospitals & Clinics

Whilst lights are generally used 24/7 in these institutions and facilities, it will be noted from the table below that the total saving over 1 year (at a low rate of R1.20/kWh) is a staggering R 48,9 Mil. The total reduction in CO2 emission amounts to 49,000 Tonnes per annum and a saving of approximately 68,6 Million Liters of Water.  

Businesses:
In the case study for the company Plastique (see table below), it was noted that apart from paying for the replacement cost of the LED lights from the savings in year one, the company saved a further R 15,000 in electricity cost in the first year.  A total saving of R 195,000 over the next 5 years without taking electricity tariff hikes or maintenance into account. Needless to say, it is a substantial saving for any small business.

It is fair to conclude that in most instances, the Return On Investment for replacing or retrofitting conventional lights with LED technology, is seldom more than 24 months. Savings over a five year period renders a LED upgrade an essential and responsible action towards reducing carbon emissions and water usage.

The case studies below prove to be a significant effort towards a GREEN economy.
