ENERGY MATTERS
Optimize Your Facility With
High-Performance HVAC Technologies
Did you know
40% of energy
Buildings account for about
consumption.
Facilities as vast as airports provide many
opportunities to conserve energy and reduce
environmental impact while increasing safety.
High ceilings create dramatic
terminal spaces, but concentrates
the heat above occupants.
What if heat were radiating from the floor instead?
Heated air that escapes through
open hangar doors is an energy
drain.
What if you weren’t relying on air to heat your facility?
Removing snow and ice from
pedestrian walkways requires constant
vigilance to reduce risk of falls.
What if you didn’t let ice form in the first place?

BOOST PERFORMANCE
With Hydronic Radiant Systems
Water carries
3,500X more heat energy than air.
It may surprise you that something as simple as fluid flowing through
pipes – hydronics – can have a major impact on energy consumption.
Hydronic radiant piping networks installed in floors, walls or ceilings
circulate warm or cool fluid to condition interior spaces.
While air is essential for ventilation, it makes sense to handle most of
a building’s heating and cooling load with radiant, because water
transfers energy more effectively than air. HVAC designs that use a
hybrid radiant-forced air system are the most efficient.
Up to 35% energy
reduction
For heating and cooling in
airport terminals throughout
the world.
Less than 5-year ROI
Can be expected for most
radiant heating/cooling
systems in commercial
buildings including terminals; hangars may
breakeven sooner (research
underway).
Targeting Ø CO 2
emissions
Geothermal energy can turn
the vast property around
aviation facilities into energy
sources, contributing to
net-zero energy targets.
Radiant Heating and Cooling
By conditioning building surfaces, in-slab hydronic radiant heating and cooling systems
provide exceptional comfort with less energy than conventional air-based systems. You
will achieve the most favorable HVAC total cost of ownership by integrating radiant as the
primary heating and cooling source and downsizing the air-handling system.
The case for radiant is especially strong in spaces with high ceilings and lots of window
glazing, because it concentrates heat energy where the occupants are while minimizing
heat gains and losses. Hands down, radiant is the most effective way to heat hangars,
because the heat energy is held in the building structure rather than the air that quickly
escapes when hangar doors are opened.
Geothermal Energy
Geothermal systems exchange energy with the earth to heat and cool buildings at
a fraction of the operating costs of traditional HVAC systems. According to the
International Ground Source Heat Pump Association, ground source heat pumps
(GSHPs) can reduce energy consumption by up to 50%.
Based on our pioneering expertise in radiant systems, we engineered a superior
geothermal ground loop system. Our RAUGEOTM system extracts more energy than
convention ground loops, reducing drilling costs, and provides easy access and control
from a manifold located in your mechanical room or in an underground vault.
Radiant Integrated With Geothermal
Radiant systems require very moderate supply fluid temperatures, typically 100-120°F
(38-49°C) in heating mode and 55-60°F (13-16°C) in cooling mode. It’s precisely in
these temperature ranges that a water-to-water geothermal heat pump operates most
efficiently. This added optimization makes an already low-energy system work at
unprecedented levels of efficiency.

Snow and Ice Melting
From parking lots to crosswalks to sidewalks, the REHAU hydronic snow and ice melting
(SIM) system will help you create safer pedestrian zones. Around equipment such as
hangar doors and people mover tracks, ice-free surfaces will keep things running
smoothly.
Operating costs are lower than you might expect; hydronic SIM uses about half the
energy of electric systems and can be comparable to mechanical snow removal costs.
Advances in hydronic controls and smart controls that even integrate weather forecasts
continue to drive down costs. With further innovation, SIM systems under runways may
one day allow more on-time flights.
Pre-Insulated PEX Piping
Aviation complexes often have central heat plants, requiring heat energy to move
underground between buildings. Pre-insulated PEXa piping assures that the greatest
amount of energy gets to the destination. Coils of REHAU INSULPEX® are capable of
long, continuous runs that snake around obstacles, allowing contractors to complete
their work more quickly.
Up to 30% less
