36 airportbusiness December 2018/January 2019 HANGAR DEVELOPMENT On that subject, while cost is always a factor, if choosing the traditional low-bid, wait-until-the-very-end-to-choose-a-general-contractor route, don’t be fooled by the lowest bid. In a low bid process, general contractors are not incentivized to provide the most realistic prices upfront, nor are the various subcontractors. This lack of incentive to provide realistic pricing is not as a result of any nefarious intent or deception, but rather, the result of the process set up for awarding the project. “As consumers ourselves, we tend towards ‘the insatiable desire for the lowest cost,’ but the lowest cost does not equal the highest value received,” adds Wenrich. As alluded to earlier, an inaccurate pro forma will further make the case for the FBO to select the lowest cost vendor- simply because it’s the one most closely matching the false assumptions. As the project matures however, the mistake of selecting the least expensive option is quickly laid bare- incremental costs begin to escalate, delays mount and finger-pointing begins. By that time, at least metaphorically, the FBO finds themselves in a dysfunctional relationship they can’t exit- because to exit the relationship means progress grinds to a halt and costs double when forced to start over. Sickeningly, a review of the original bids will only then reveal that the highest cost bid- the one not selected- was in fact accurate all along. In summary, choose an expert firm at the beginning, involve them in developing the pro forma on day one, and the result is not only the best value, but often the lowest cost. In our next installment in this series, we’ll discuss techniques for securing tenant commitments for the to-be-built hangar, long before construction commences.

While that’s great for storing multiple aircraft inside them, these unique designs lead to several facility management challenges. Energy costs, temperature control, air quality and safety/comfort issues can all arise in this environment. In an effort to mitigate these challenges, more and more hangar owners are installing high-volume, low-speed (HVLS) fans. HVLS fans can significantly improve the comfort and health of pilots, guests and mechanics. On top of that, they can save building operators substantial amounts of money by making existing heating and ventilation systems more efficient, while providing additional benefits in buildings with no air conditioning. HVLS versus other types of fans High-speed ceiling or floor fans can help increase air movement, but they have several disadvantages when compared to HVLS ceiling fans. HVLS fans can move larger volumes of air with a single fan covering an area up to 22,000 square feet. In fact, a single HVLS fan can replace as many as 10 to 20 floor fans, without any of the clutter caused by electrical cords on the ground. HVLS fans consume less energy than traditional, high-speed ceiling or floor fans and even produce less noise. New direct drive, gearless motors are available in some HVLS fan models that negate noise even more, which can be beneficial to aviators and mechanics who need to hear engines and props clearly while working on aircraft in the hangar. These types of gearless motor fans don’t use oil, so there’s no fear of a drip that might compromise aircraft or interfere with operations. HVLS Complements HVAC The long blades (up to 24-foot diameter) of HVLS fans spin much more slowly than a traditional ceiling or floor fan. Their unique blades are specially designed to capture the maximum amount of air and push it softly to the floor. In the summer, the gentle breezes created by an HVLS fan keep employees and visitors cool by quickening the evaporation of sweat. In winter, in a process called destratification, the fans take the warm air created by an HVAC system and pull it down from the ceiling to the floor level, allowing people inside to be more comfortable with a lower thermostat setting. Energy Savings Add Up A 24-foot diameter model uses 1,500 watts per hour for cooling and as little as 100 watts for destratification, making HVLS fans extremely energy efficient. This translates to operating costs of as little as a few cents per hour. During the winter months, HVLS fans can reduce energy consumption by up to 30 percent. When used to supplement air conditioning, the fans help lower the perceived temperature – which means thermostat set-points can be raised. Because energy costs are reduced roughly 4 percent for every degree the set-point is raised, a 3- to 4-degree increase in the set-point can reduce energy consumption by 12 to 16 percent. With year-round use, HVLS fans can pay for themselves in as little as 6 months. HVLS fans are capable of covering a large area and those benefits are only more pronounced in taller buildings, as the air it pushes toward the ground only widens in a conical shape. Rite-Hite
