Many temperature control systems believed to be operating optimally really are not. The building operating team usually does not access the temperature control system regularly enough to review its operation and efficiency. The building operations team can tune up and/or re–commission the building’s existing control system to improve efficiency. Some of the key issues to review to make sure that the control system is accessible and that the data are reliable include:
- • Do the building operators regularly access the control system?
- • Can the building operator review and make key changes on the control system?
- • Does the building control system have a graphic user interface?
- • Do all the various graphic models represent all of the HVAC systems in the building?
- • How is the computer system response time to commands and displaying information?
- • Are there communication issues between the control system and the HVAC devices?
- • Does the data for the HVAC systems make sense?
Secondly, focus on a few key operational parameters to improve operational efficiency would be:
- • Scheduling of the HVAC systems to match the building’s occupancy schedule
- • Free Cooling: Economizer set points and strategies should take advantage of times when free cooling makes sense to save energy
- • Simultaneous heating and cooling: Is a space or an airstream being heating and cooling operating at the same time when it is not needed?
- • Set-points: Review all set points for temperatures, air flows, static pressures, etc. to make sure they make sense
- • Control: Do the HVAC system appear to be controlling according to their sequence of operations? Are space temperatures achieved?
A regular inspection of the building automation system, addressing updates and set–points, has the potential to reduce operation costs.
What is the true cost of the EPA’s Clean Power Plan?
Questions remain. Will the EPA’s Clean Power Plan cost jobs? What will be the true cost for the proposed EPA’s
Clean Power Plan?
What will be the cost for the proposed EPA’s Clean Power Plan?
One study from the “Affordable Electricity: Rural America’s Economic Lifeline” released by the National Rural Electric Cooperative Association (NRECA) stated that more than one million jobs will be lost in 2021 if the EPA’s impact on Clean Power raises the cost of electricity by only 10%.
This job loss would equate to almost 500,000 of those jobs lost to the rural areas in America. The study details a devastating relationship between higher cost for electricity and the correlation to jobs lost.
A 25% increase in the cost of electricity in 2010 would result in a 2.2 million jobs lost. More than 890,000 jobs lost would be in the rural sectors.
In terms of GDP from 2020 to 2040, a small 10% increase in the cost of electricity results in a cumulative loss of $2.8 trillion and a larger 25% increase in the cost of electricity would be a cumulative $5.4 trillion loss.
The study indicates that on average 25% of the co-op households earn less than $25,000 a year which is 11.5% less than the National average income. The impact of higher cost for electricity would be on those who can least afford it.
The NRECA research indicates that the EPA’s proposed Clean Power Plan would have a 10% minimum increase to the cost of electricity. The NRECA represents more than 900 private, not–for–profit, consumer owned electric cooperatives, which provide service to 42 million people in 47 states.
This study highlights the real life cost of higher electricity prices of which must be understood by the political proponents of “clean power” and the EPA. Any modest gains in rural America would be wiped out with the higher electricity cost of such impact in the proposed EPA’s Clean Power Plan.
