Temperatures are high, but these techniques will help you keep your energy costs low:
- Reduce HVAC System Operations When Building or Space is Unoccupied
- Minimize direct cooling of unoccupied areas by turning off fan coil units and unit heaters, and by closing the vent or supply air diffuser
- Turn fans off
- Install system controls to reduce cooling/heating of unoccupied space
- Minimize Exhaust and Make-Up Air
- Keep doors closed when air conditioning is running
- Properly insulate walls and ceilings
- install thermal windows to minimize cooling and heating loss
- Implement a Regular Maintenance Plan
- Check fans for lint, dirt, or other causes of reduced flow
- Schedule HVAC tune-ups (with us!) – the typical energy savings generated by tune-ups is 10%
- Replace air filters regularly
- Upgrade Fuel-Burning Equipment
- Install turbulators to improve heat transfer efficiency in older fire tube boilers
- Install automatic combustion control systems to monitor the combustion of exit gases and adjust the intake air for large boilers
- Install electric ignitions instead of prior lights
- Evaluate Boiler Operations
- Investigate preheating boiler feed water
- Adjust boilers and air conditioner controls so that boilers do not fire and compressors do not start at the same time but satisfy demand
- Use hot water from boiler condensate to preheat air
AEP Ohio’s gridSMART program proved greatly beneficial to our customers in the year 2011. Bruner submitted 60 rebate applications and earned our customers more than $300,000 in incentives. We look forward to topping those numbers in the year 2012!
It’s finally happened: T12 lamps will be phased out of production starting July 2012. This has been a long time coming since the U.S. Department of Energy’s fluorescent lighting mandate stopped the production of the magnetic ballasts most commonly used for the operation of T12 lamps in July 2010.
The Good News
There is large energy savings when switching from T12 to T8 lamps – up to 33% in energy costs per fixture. Even better news is that if you make the switch before July, AEP’s gridSmart program offers rebates for switching from T12 to T8 or T5 lights.
How to Prepare
Begin discussing your options for replacing your T12 lights. If you complete the T12 project or get the pre-approval in before July and then you have 90 day to complete.
Contact us! We can assist you in replacing your T12 lamps, and evaluating your energy consumption in the process. There may be even more savings out there for you!
If you’ve already switch out your T12 lights, check out our commercial energy savings e-book for more tips to decrease your energy consumption and your utility bills!
Providing mechanical solutions that save energy is what we do, but before our customers can agree to an energy conservation program, they first need to know the facts.
Early this week, Hilliard City Schools was presented with a rebate check in the amount of $111,622.42 from AEP Ohio’s Business Incentives program following an energy conservation program in conjunction with Bruner that began in early 2011.
The Hilliard City Schools project included the following energy efficiency measures:
- 40-ton chiller replacement at Scioto Darby Elementary
- T8 high-output, high bay lighting retrofits in 22 gymnasiums across the district
- Occupancy lighting sensors in all gyms and some cafeterias
- Parking lot lighting retrofit to inductive lamps
The projects represent an annual electricity savings of 728,000 kilowatts per year and an annual cost savings of $58,242.64.
To date, Hilliard has received the largest rebate check of any school district in Ohio. Following closely behind was Dublin City Schools, another project Bruner was fortunate enough to be part of, with more than $90,500.
To get started with an energy conservation program for your district or organization, contact Eric Kuns, VP of the Solutions Group, at (614) 334-9000.
As you can see, the benefits are clear.
The words “Go Green” are no strangers to your ears, your eyes, or your brain. This year, why not make a commitment to going green by implementing a Green Team in your office. Here at Bruner, our Green Team has been hard at work since October 2010 on three green initiatives: building upgrades, green office practices, and employee development.
Most recently, Bruner has focused on building upgrades. Our 30,000+ square footage warehouse has received both lighting and heating upgrades. A total of 160 lighting fixtures were replaced, resulting in a rebate submission of $7,600. All 400-watt metal halides were swapped for 234-watt T5 Hi Bay bulbs. Any T12 lights were exchanged for reduced wattage T8 bulbs. Bruner service technicians were responsible for installing high-efficiency heaters with programmable thermostats for all of our warehouse space to reduce energy consumption. With the energy they’ll save, the units will pay for themselves within 3 years.
What can you organization do to Go Green?
Did you know that in 2006, Energy Star reported that K-12 schools in the US spend more than $7.5 billion annually on energy? Energy costs are the largest operating expense for K-12 school districts after salaries and benefits. The good news is that taking measures to improve decrease energy usage can not only be done without negatively affecting classroom instruction, but it may even lead to a more ideal learning environment for students, as well as extensive cost savings.
There are several aspects of building performance that prove to be crucial in providing an environment conducive to learning. “Research has shown that a relationship between facility conditions and absenteeism, teacher turnover rates, and occupant health,” Energy Star reports. Fortunately, many aspects of an energy conservation program can improve the following factors, while cutting energy costs.
- Student safety and security can be improved with proper exterior lighting and adequate lighting in hallways and stairwells.
- It is also important to keep in mind that natural daylight has been shown to enhance learning and so should be utilized wherever possible without negatively affecting other important aspects of lighting design. Visual comfort depends on having an adequate amount of evenly distributed illumination. “Daylighting in Schools: Reanalysis Report,” a major study conducted in 2003 by the Heschong Mahone Group, found that on average daylighting improves learning by 21 percent.
- Indoor air quality can be bettered with ventilation as well as by removing the source of pollutants. High concentrations of these pollutants, like carbon dioxide (CO2), have been correlated with sickness and poor academic test performance.
- The temperature of educational facilities also has an impact on student performance. Cold temperatures reduce dexterity, whereas warm temperatures reduce alertness. Temperatures that fluctuate frequently and widely can hinder children’s ability to focus.
- Noise from outside the building, interior hallways, and building systems (such as fans, boilers, and compressors) can be a significant distraction to students. Being able to hear properly is important because up to 60 percent of classroom activities involve spoken communication.

These days, not attempting to save energy or “go green” is quite the faux-pas. So you request that your employees recycle their paper waste and you purchase ceramic coffee mugs instead of Styrofoam cups. But how else can your company cut down on energy? Evaluate your lighting situation.
LED lighting fixtures can save up to 85 percent of the electricity used by incandescent bulbs. Most of the energy emitted from incandescent bulbs is converted to heat instead of light; that’s why if you touch an incandescent bulb after it’s been turned on you will burn yourself. LED lighting also lasts up to 50 times longer than incandescent lighting.
LED lighting can save up to 50 percent of the energy used by CFLs and between 20 to 30 percent of the energy used by fluorescent tube lighting because LEDs don’t contain hazardous materials, such as mercury, like fluorescent tubes and CFLs do. LED lighting also uses solid-state technology, which allows effective dimming and eliminates flickering, unlike most fluorescent lights that cannot be dimmed and often flicker.
Where can you implement LED lighting? Practically everywhere! Options include: post-top lights, area lights, roadway lights, flood lights, and garage lights among others.
To top it all off, LED lighting can be part of your Energy Conservation Program with Bruner, and supply only a small portion of your every savings. Contact us today to see how LED lighting and other conservation measures can cut down your utility bills.
