Morning All
The question Sidney ask is exactly why I am here. Until now the energy consumption was not a criteria for purchase. But as it is very big ISO requirement we are getting there. Clause 8.3 requires to set “criteria for evaluating energy performance over the planned or expected operating lifetime, when procuring energy using products, equipment and services which are expected to have a significant impact on the organization's energy performance.”
our consultant sent me example form from 50004 - here attached and off course that opened complains from manager "There is going to be a lot of information entered onto that form that will be of no use to anyone once it is written down and it will take a lot of effort to find some of that info out."
what do you guys use?
can someone please share what format works within your organization
thank you
One basically need to look at the efficiency of equipment in regards to energy consumption and answer a few questions Including:
How many hours a day the equipment will run
How many kWh will it use over that operating time
Figure your cost to operate based on current energy prices
What can be done to lower that cost thru changes in operation times, use of NEMA efficient motors, VSD, etc
Make sure the motor is the correct motor for what is being done
Make sure that PM is done - as most new equipment is running at about 70% efficiency due to PM not being done
