Knowledge is power. And from a design standpoint, knowledge can harness power. Read this month's bulletin and you too can let the force be with you. Alright enough with the Jedi talk...but this is some future forward stuff.

What's GHP?

Ever heard of Natural Gas Heat Pump Air-Conditioners (GHP)? They've been utilized globally for over two decades and have proven to be an energy saving and sustainable alternative to electric systems. Maybe you've heard of them, maybe you haven't, however this technology has been specified for private, public and government applications throughout Asia and Europe for decades. You read that right. Decades.

The rest of the world is already in tune with GHP, so why has the U.S. market been so slow to pick up on this energy-saving technology? The network of knowledge has been slow, but Mariano Engineering got wind of this product in 2003 through working with IntelliChoice Energy - the exclusive distributor of NextAire™ Gas Heat Pumps, a product line for North America.

Let's look at the advantages of GHP in the market; design flexibility, easy installation, low sound levels, the ability to work well in multiple zones, and of course, it's energy efficient and environmentally sustainable.

Design Benefits: One GHP system can replace multiple outdoor electric condensing units and gas furnaces. Precious square footage is also saved, when compared to chiller-boiler systems, because GHPs do not require cooling towers or mechanical rooms. And they operate quietly at less than 57 decibels. If exterior visual appeal is a design priority, the system can be conveniently located up to 400 feet from the building - out of sight.

GHP has a smaller equipment footprint which allows architects limitless opportunities when planning and designing spaces. This means more open and flexible floor plans and pleasing rooflines.

How? GHP can have ducted or ductless air handlers to accommodate any plan or placement requirements. There aren't any roof penetrations for exhaust venting, and combustion air openings are unnecessary. Enabling simplified piping design, which reduces or eliminates soffit cost. Also, units are well suited for retrofit, as well as new construction applications for commercial and residential structures.

What's the Cost? GHP running and maintenance costs can be as much as 30% less than an electric heat pump, with power consumption up to 80% less. Which results in saving water, given that a 1/2 gallon of water is consumed for every kilowatt of electricity produced - 8,000 gallons of water can be saved by using just one GHP.

Energy efficiency, outstanding environment advantages, and energy cost savings to building owners and operators. Using natural gas as its primary fuel

Want to Make Clients Happy? Overall, GHP reduces construction costs, provides significant LEED points, and there's a reduction of maintenance servicing over the life of the building. It's an energy-efficient and carbon conscious choice.

 8Ways to be Rock Star Cool!  


1.  Get LEED points for green-building certification using GHP

2. Show you care. Offer clients a cost-efficient system that's easy to maintain

3. Look Ma! No cooling towers or mechanical rooms! (magically free up square footage)

4. Be thoughtful. Design multi-zone temperature controls for the comfort of everyone in the building

5. Reduce noise pollution. GHP has a low sound level when running

6. Truly innovate. Optimize construction potential by taking advantage of ductless and ducted capabilities

7. Have Mariano Engineering design an all-in-one, space-saving unit that can dually heat and cool

8. Ask your engineer to be the biggest loser - to reduce a building's HVAC system electrical demand by 80% 

Yoda would be proud.
