Organic HVAC Systems

This morning after grabbing my first cup of joe at work I received a message from one of our community members John J. Jerabek alerting me to a research doc that NASA put together. So I hunkered down at my desk preparing myself for a 50 page report; to my surprise it was concise, to the point and contained some great information I haven’t seen before about going green at home.

The article John sent over talks about Bill Woverton, an environmentalist who worked with the U.S. military to find ways to clean up the mess left by biological warfare. One amazing finding that Woverton came across during his stint with the military was plants that could actually eliminate Agent Orange. Woverton left the military and soon after received funding from NASA to start running some new experiments which focused around the topic “If man is to move into closed environments, on Earth or in space, he must take along nature’s life support system.” i.e. plants.

Based on Woverton’s research at NASA and now his own organization Wolverton Environmental Services Inc., he published some of his findings in “How to Grow Fresh Air: 50 Houseplants That Purify Your Home or Office.” and “Growing Clean Water: Nature’s Solution to Water Pollution,” for consumers to start utilizing his findings in their homes. Woverton had many amazing breakthroughs but his recent research is what took me by surprise.

“On the home front, in a partnership with Syracuse University, Wolverton Environmental is engineering systems consisting of modular wicking filters tied into duct work and water supplies, essentially tying plant-based filters into heating, ventilation, and air conditioning (HVAC) systems. This whole-building approach has recently been licensed by Wolverton to Phytofilter Technologies Inc., of Saratoga Springs, New York, which is currently constructing a prototype of a system that is intended to clean the water and air circulation systems of entire buildings using the natural abilities of plants. The design includes units that are built into existing HVAC units. The plants can be placed throughout buildings, in atriums, or in roof gardens and then hooked into the building’s HVAC units through forced-air filters.”

Wolverton Environmental Services Inc. designed this sustainable ecosystem to show how a building’s circulation system and a rooftop garden could work in tandem to clean indoor air.

What’s so amazing about this system is that it directly ties making your home more energy efficient to the shell of your home. When you make retrofits or seal up the shell of your home, you’re reducing the amount of natural air flow through out the house. If a home is sealed too tightly you can come across major health issues such as the sick building syndrome. With Woverton’s findings he might be able to make homes more energy efficient by allowing a home’s shell to be sealed tighter without increasing the risk of health issues. Moreover his solution doesn’t call for more obtrusive materials in your home that increase your carbon foot print or energy consumption. Woverton has been discovering amazing technological advances by going back to the natural basics.

    I would like to see some actual pictures of this type of system working.  Seems far fetched to me.

    You can see a practical working example of a real life building using this approach very successfully at www.pbcnet.com

    Organic HVAC can give you better results.I would like to know more about this system.

    Has anyone tried to estimate the cost of a single family house HVAC system retrofitting? Would it be still money-efficient to retrofit existing systems or it would only make sense from the financial point of view to install such systems in new construction?

    We are a contractor in the HVAC industry. The thing I am always looking at is how will this effect our industry. There is always a new thing coming out. However is it easy to install. Meaning how much training is involved and will there be any at all.  I can understand new construction but how about rebuilds.

    In modern buildings the design, installation, and control systems of these functions are integrated into one or more HVAC systems. For very small buildings, contractors normally "size" and select HVAC systems and equipment. For larger buildings, building services designers and engineers, such as mechanical, architectural, or building services engineers analyze, design, and specify the HVAC systems, and specialty mechanical contractors build and commission them. Building permits and code-compliance inspections of the installations are normally required for all sizes of buildings
