PRESIDIO OF MONTEREY, Calif. (Oct. 20, 2022) — A refurbished heating and air flow system on the Ord Army Neighborhood’s Publish Change not solely saves $43,000 in vitality prices yearly, but in addition makes the constructing extra comfy for purchasers and workers.

Richard Thorne, vitality supervisor for U.S. Army Garrison Presidio of Monterey, stated the venture is one among 4 vitality initiatives the garrison accomplished this 12 months that he expects will save taxpayers a complete of greater than $52,000 yearly. Whereas the garrison deliberate three of the initiatives effectively upfront, a easy remark led to the fourth — exhibiting it at all times pays to be looking out for vitality financial savings.

The PX venture is the most important of the 4 initiatives, and to perform the financial savings, contractors refurbished all the present heating and ventilating items that serve the primary PX retailer and adjoining mall shops, Thorne stated. Additionally they added new controls to the system.

“The items are from the late Nineteen Seventies or mid Nineteen Eighties and had not been overhauled in a really very long time,” Thorne stated. “It was ripe for an vitality venture.”

Given the cool temperatures in Monterey year-round, air con will not be obligatory, so the system pulls air from outdoors the constructing and distributes it inside, Thorne stated. The previous system ran all day, however the brand new system, which got here on-line within the spring, runs solely 20% of the time.

The brand new unit’s air dampers and controls modulate the fan pace and damper place to supply the correct quantity of air for heating, air flow and cooling, Thorne stated. Vitality financial savings comes from lowering the fan pace in heating and air flow modes.

The system’s computerized management panel permits operators to see if one thing is flawed with the system and repair it earlier than clients and workers even discover there’s an issue, Thorne stated.

As well as, the Army and Air Drive Change Service paid for the substitute of getting old fluorescent lighting with extra energy-efficient LEDs, Thorne stated.

“This vitality venture, together with the AAFES lighting venture, as resulted in virtually 30% vitality financial savings when evaluating FY22 to pre-COVID FY2019,” Thorne stated. “With the brand new controls and air dampers, the constructing is way more comfy and fewer stagnate.”

One other venture in Constructing 618, Munzer Corridor, an administrative constructing for the Protection Language Institute International Language Heart, concerned adjusting the heating and cooling airflow charges and the surface airflow for every variable air quantity zone field to the proper quantities, Thorne stated.

Thorne stated that any time technicians can lower a motor pace, it results in energy financial savings. “Even small adjustments in pace adjustments can lead to vital energy financial savings,” he stated.

As well as, workers usually go away the entrance doorways to the constructing open for an ocean breeze, Thorne stated, and this eliminates the necessity for a fan. “Once more, saving fairly a little bit of vitality preserving the fan off when it’s not wanted,” he stated.

These easy programming adjustments resulted in about 20% vitality financial savings evaluating FY2022 vitality payments to pre-COVID 2019 vitality payments, or a financial savings of about $3,000 yearly, Thorne stated.

One other venture at Constructing 4283, the Porter Youth Heart, saved about $6,000 yearly by adjusting the heating system controls to higher match the occupancy utilization, Thorne stated.

The heating system was approaching too early, Thorne stated, and the air techniques additionally got here on too early—pushing chilly air into the constructing till the heating system began.

To repair the issue, technicians up to date the system’s schedules to begin the heating system first, then the air system about half-hour earlier than occupancy, Thorne stated. Additionally they programmed in all of the federal holidays. Along with saving cash, the constructing can be extra comfy.

The fourth venture Thorne spearheaded himself after noticing {that a} fan on the World Café throughout the road from his workplace was at all times on.

“Throughout a latest espresso cease I requested the World Café proprietor in regards to the fan,” Thorne stated. “It seems the fan is managed by a easy change. The fan is left on to make sure the area will not be too sizzling within the morning. As soon as that kitchen will get going early, it takes no time earlier than the area is admittedly heat, particularly if there was no air circulation earlier than opening.”

Thorne submitted a piece request, and technicians will set up a easy programmable timer and reverse the fan’s airflow path to blow air into the area as a substitute of exhaust, Thorne stated.

The easy repair will scale back the fan vitality consumption by about 70% and save about $90 yearly, Thorne stated.
