Holloman Air Force Base has undertaken several energy conservation projects to reduce energy consumption and costs, including retro-commissioning HVAC systems, replacing lighting with more efficient options, installing advanced metering, using treated wastewater for irrigation, upgrading stadium lighting, replacing outdated office lighting, expanding their energy management control system, and plans to install solar arrays at housing and develop a larger solar farm. These projects are estimated to save up to $500,000 per year in total and help meet federal renewable energy mandates.

- 2. $0.00 $100,000.00 $200,000.00 $300,000.00 $400,000.00 $500,000.00 $600,000.00 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Jan Energy Consumption FY‐2010 FY‐2010 Retro-Commissioning the Heating and Air Conditioning (HVAC) Systems When new buildings are constructed the HVAC equipment is tested and set to run at peak efficiency (commissioning). However, during the next 4-5 years the HVAC sys- tems tend to drift away from peak efficiency due to operation changes, building layout changes, and equipment failure. During the 2011 Fiscal Year the HVAC Systems were updated in the following buildings: Building 29‐ Headquarters Building 224 – Learning Center Building 588– Fitness Center Building 222—Personnel FY12 will include retro-commissioning the SPCS Command, GAF HQ, MXG Command, Child Dev. Center, and the Youth Center. Summer Peak Retro-commissioning would help regulate energy consumption during the peak summer months. Retro-commissioning, refers to the recalibration and replacement of failed equipment in the HVAC system to regain the optimal levels of energy efficiency. Retro-commissioning can save up to 20% in en- ergy costs. SAVINGS UP TO $90,000 PER YEAR
- 3. High Bay Lighting Replacement HAFB hangar buildings have cut lighting costs by up to 40% by going from HID High Bay Lights to T-5 Fluorescent High Bay fixtures with lighting sensors and natural daylight features. High Bay Lighting has been replaced in the F-22 and GAF hangars and various ware- houses totaling 1.2 million sq ft (22 bldgs). Why we need it : The Air force is mandated by the Energy Policy Act to reduce energy consumption by 30% by the year 2015 Combining new lighting technology and natural lighting will reduce Holloman’s energy consumption Project completed in FY2011 Lighting sensors automatically turn off lights or adjust levels depending on the available natural light. SAVINGS UP TO $200,000 PER YEAR
- 4. Advanced Meter Reading Electric and Gas Meters 2nd Phase Out to Contract for FY2012 40 additional building (.9 million sq ft) Advanced meter reading, or AMR, is the technology of automatically collecting energy consumption, diagnostic, and status data from energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting and analyzing. 1st Phase Completed in FY2011 54 buildings (2.6 million sq ft) Why we Need Advanced Meter Reading: ͏ Usage trend analysis will help pinpoint high energy use buildings and correct energy waste on base. ͏ Correct data for accurate billing and recognition of actual energy consumption will promote energy consciousness. ͏ This technology saves the base the expense of monthly trips to each location to read meters. v v “Smart Meters” Energy use and energy demand is sent from the building meters to a base station. This information is then transferred to computer servers and readily available for energy reports. AMR is done for all buildings measuring 35,000 sq ft or more. SAVINGS UP TO $250,000 PER YEAR
- 5. HAFB Golf Course Irrigation Water Conservation Plan Civil Engineering has constructed a supplemental irrigation source for the Golf Course to use treated effluent from the Waste Water Treatment Plant instead of potable water.. Using effluent water saves approximately 70 million gallons of potable drinking water per year and helps us meet our water conservation goal of 2% reduction per year since 2007. SAVINGS UP TO $117,000 PER YEAR Effluent water will be collected in a storage tank until water application during the irrigation cycle. This project reduces water consumption on Holloman AFB by 20%.. Project In-Place since Sept 15, 2011
- 6. Stadium Light Replacement West and Main Ramp The current lighting over the aircraft hangars was installed for security purposes over 40 years ago. Adjustments to the lighting layout will improve lighting and increase efficiency. Why We Need It: Cut the lighting costs at the ramp. Maintain security lighting to the Air Force stan- dards. Improve flight safety. Main Ramp West Ramp SAVINGS UP TO $80,000 PER YEAR The new lightings system have a more efficient layout using advanced lighting technology. This project will lower the lighting poles from 150’ to less than 70’.
- 7. Why We Need It: The office lighting upgrades can save up to 40% in energy costs. The 40 year old T-12 fluorescent technology will be replaced with the latest T-8/ T-5 fluorescent technology. The lighting upgrade project covered 2.2 million sq ft. (over 100 facilities) on Holloman AFB. 41% of the buildings on base (mostly offices) were upgraded to the efficient T-8 lighting. T‐12 Lighting 59% T‐8 Lighting 41% Lighting on Holloman AFB Replacing Inefficient Lighting Systems T-12 T-8 SAVINGS UP TO $150,000 PER YEAR
- 8. Upgrade and Expand the Energy Management Control System (EMCS) on the Base The EMCS is a centralized computer control system that controls the large heating and air conditioning system on the base. Why We Need It: Better control of the temperature setting within buildings when not in use. Help pinpoint maintenance issues. Control the temperature setting on the base. Upgrade the current software to the state of the art Air Force approved software The EMCS Project is design to expand the system to control up to 179 bldg. SAVINGS UP TO $500,000 PER YEAR
- 9. Soaring Heights Housing Roof-top and Ground Solar Arrays Holloman AFB offers an exceptional opportunity to take advantage of year-round sun, open spaces and homes able to accommodate roof mounted systems. Soaring Heights will generate electricity at a peak rate of ~ 1300 kw and reduce the consumption of electricity from the community’s electric grid. Why We Need It: Federal mandates require the Air Force to have 25% of their electrical power supplied by renewables sources by the year 2025 Combined, the ground solar array and solar roof mount systems could potentially reduce more 570 million pounds of carbon-dioxide . Proposal to install ground solar arrays on 2 sites within the soaring heights housing area: West Gate Array Mesquite Array A solar array would compliment the energy -efficient building design, materials and appliances throughout the new homes.
- 10. Is a Solar Farm the future of HAFB? The proposed idea is to build a solar electric ar- ray that would produce a minimum of 5 mega- watts near the Atlas Substation. Request for proposals will be posted upon completion of the Environmental Assessment Report and a market analysis on solar farm construction. The solar farm is projected to produce up to $4.1 Million of power per year. The solar arrays would help HAFB achieve this goal. Why We Need It: The Air Force is mandated by the Energy Policy Act of 2005 to have 25% of their electrical power supplied by renewable sources by the year 2025.
