Vixctoria’s State Library saves $60,000 a year through energy efficiency

VICTORIA’S STATE LIBRARY REAPS THE BENEFITS OF ENERGY EFFICIENT TECHNOLOGY
PACE, By Hartley Henderson   6 October 2011 Over the last ten years the push for energy efficiency has been rapidly gathering momentum, particularly in relation to productivity improvement and reduction of carbon emissions.

During a recent visit to Australia from Low Voltage Drives headquarters in Finland, ABB group vice president, Pekka Tiitinen, pointed out that 65 percent of all energy consumption at industrial sites goes through motors, and that the biggest challenge is ignorance of the scope for savings…. “Some 50 percent of carbon reduction comes from energy efficiency improvement from renewable energy and other non-fossil, plus carbon capture storage,” he said.

“Australia is a front runner in legislating for energy efficiency and recognising the benefits of energy appraisals for industry and large buildings.

In industry, cost/benefit analysis demonstrates that big savings of up to 50 percent can be achieved, with payback typically in one to two years and sometimes even five to eight months. “The easiest way to add more electricity capacity, is to improve the energy efficiency that would release existing capture in new consumption. Nowadays, more and more systems are playing a key vital role in that.”…

The State Library of Victoria was founded in 1854 and is a reference and research library for over one million visitors a year.

It holds more than two million books and occupies an entire city block of two hectares, comprising reading rooms, galleries, exhibition spaces, conference centre and cafe. Jussi says that an energy appraisal carried out at the library concluded that significant energy savings could be made by replacing the existing HVAC flow control, which used throttling valves, with variable speed drives..

Jussi advises that by using 15 ABB standard drives for HVAC, from 5.5 kW to 55 kW, energy savings of between 30 to 60 percent were achieved across the various applications. “With combined motor ratings of 400 kW and 24/7 plant operation, the total energy consumption was reduced by 1,800 MWh annually, saving the library nearly $60,000 per year. Payback, including maintenance savings, was achieved in just 14 months,” he said…. http://www.pacetoday.com.au/news/victoria-s-state-library-reaps-the-benefits-of-ene
