January 2014: Maui’s Cool Catchment

A Novel Collection System in Maui: From Air Conditioner Drip to Garden Water

Warren Jessop of Maui Catchment Service has designed and installed a HOG water catchment system for air conditioning condensation  – a use that demonstrates the multi-functional adaptability of the tanks.

“If you have plants around the building, why not water them with the AC condensate?” asks Jessop, who was looking to move water from a potential problem spot to “where it could do some good” hydrating thirsty plants with his pressurized (non-gravitational) HOG install.

Jessop’s client, Volcano Maui Group, LLC owns a three-level commercial office building in Lahaina, Maui. A basement-level private parking lot is available for tenants. The condensation generated by building’s AC systems (12 in total) is collected and discharged via one main pipe into in a rain drainage sump located below the basement parking lot, where the presence of the water presents various maintenance issues.

The solution? Plumb the AC collection pipe to a  four-HOG system, and use a pump to redistribute the water via pipes and drip irrigation to the yellow hibiscus, red ginger, multi-colored crotons, night-blooming jasmine and other plants growing outside in the gardens of the exterior parking lots.

Maui_car_garage1The catchment system is installed around a central elevator shaft, the location of which made the narrow HOG tanks the best choice for the job. This HOG installation collects water for distribution without restricting driver access or maneuverability in the underground parking lot.

“Rainwater HOG [tanks] make it easier to catch the water without taking up a lot of space,” says Warren Jessop, who sees the HOG air conditioning catchment system as a replicable model for other commercial buildings.

Maui_car_garage_cheat_sheetThe ‘primary port’ tank (shown above) serves as the collection point from which the air conditioning water is dispersed across the four-unit system, as well as the distribution point from which the water is pumped out.

“The tanks are drip free,” reports Jessop, who installed a 5′ tall 3/4″ PVC pipe inside the ‘primary port’  tank which sends out the water with the help of a pump. It is accessed via a piggy-back float switch in the tank that sends irrigation water out automatically once the reservoir reaches a certain level. Pipes along the ceiling lead the water to a drip-irrigation system for the outdoor vegetation.

Maui_car_garage_frontTransforming unwanted air-conditioning waste into water-savings is just one out-of-the-box (or maybe we should say, around-the-box) way that HOGs, with the guidance of an educated systems-installer, can save the day.

Maui Catchment sourced the four HOG tanks from Green Builders Depot.

January 2014: B.U.G. (Beautiful.Useful.Green) Design

Insights and Tools for Creative Thinking

HOG Designer, architect and innovator Sally Dominguez is mid-course Winter semester at Stanford teaching a continuing studies class on Insights and Tools for Creative Thinking.

We’re sharing it here in our B.U.G. section because the classroom setting articulates and teases out some of the values that Sally brings to HOG as co-founder and designer. The class is an expansive and exciting illustration of where our core values of innovation and sustainability can lead.

left brain right brain
Why is it beautiful? This class full of creative chaos, group projects and outside-of-the-box problem-solving is at capacity with 48 students (about a 50/50 split between traditional/non-traditional students and men and women) and shows the applicability of creative thinking in manufacturing, business and beyond.

Why is it useful? Sally brings an outsider perspective to the classroom and finds herself in good company with philosopher Jacques Derrida, writer and neuroscientist Jonah Lehrer, maker and architect David Heatherwick, writer of The Toaster Project Thomas Thwaites, and artist Banksy, among others. Ultimately, through hands-on exploration and creative play, participants will leave with a personalized tool kit for the creative prompts, approaches and useful disrupters that best suit each person.

Find inspiration with Sally’s Creative Insight crib notes here.

Why is it green? Students cozy up to William McDonough’s game-changing Cradle to Cradle philosophy, learning how it applies to them. From sessions including reconsidering negative space, thinking backwards, re-thinking what you have, and assemblage and deconstruction, sustainability is taken as a base point and used as a benchmark and goal.

The Whole HOG: Oct/Nov 2013

Water-centric Green Design News

After a historic dry stretch here in California, the skies are full of sweet, sweet rain. Almost as full as our October/November newsletter, brimming with two months worth of water news! We check in with some familiar folks: following Team ASUNM to Irvine, California as they compete in the Solar Decathlon, and visiting a GREENheart Building installation in the Chicago suburbs that showcases the versatility of our HOG tanks in the hands of an experienced builder.

Two separate reports highlight water’s value and risks to the U.S. water system from aging infrastructure to water-guzzling energy production methods. We’re back to the world of whimsy, and clever design with Lampbrella, featured in this month’s B.U.G. Design section. Come on and dive in, the water’s fine!

Oct/Nov 2013: An Ingenious Array for a Green Roof in the Chicago Suburbs

GREENheart Buildings Inc. Designs a Water Capture System for a Residential Green Roof

What happens when homeowners want to feed a green-roof with harvested rainwater, but their downspouts and gutters head straight down to the ground? Well, the Alexander/Fuoss family called in Michael Ruehle of GREENheart Buildings Inc. to design an ingenious (and partially hidden) HOG system to capture rainwater and pump it back up to the rooftop garden. Take a photo tour with us!

Eight HOG tanks have been installed at the Alexander/Fuoss residence in the suburbs of Chicago. The front of the house, though, shows no sign of the owners’ water-wise installation.

It’s only at the back of the house, behind the garage, that we see the first array of four HOGs that will be used for soaker hose irrigation of the garden. The mounting bar has been extended should the family decide to add two more HOG tanks to this modular unit.

The backyard garden, with newly planted vegetation, holds secrets of its own. Four tanks are installed underneath the deck. Captured rainwater heads north with an assist from a gravity feed pump to water the green roof above.

The HOG tanks are under the deck and stairs. Concealed behind the green plant at right is a clear hose with a screen insert that allows the owner to see the water level in the HOGs.

GREENheart Buildings has made a complicated solution look simple. We’re especially impressed with the installation that feeds this rooftop garden. Water is captured from about 1/4 of the total roof area, fed to four concealed HOG tanks under the deck, and pumped back up to irrigate the three garden areas on the roof.

Highlights, for us, from the Alexander/Fuoss residential install include:

1)This ingenious install of HOG tanks includes two separate modular set-ups for one home. One system is installed horizontally, the other vertically – a nice display of what is one Rainwater HOG’s primary strengths in the rainwater tank market, a solid, elegant design that allows for multi-purpose, modular installs in tight space.

2) Basic common sense features for increased ease of use for the owners, like a manual timer pump and the screen insert for checking HOG water levels. It’s this kind of attention to detail that distinguishes a high-level installation.

For example, on his choice of pumps, Michael Ruehle explains, “A simple manual timer was chosen to allow the owner to set the pump to run for 5 to 10 minutes when the green roof actually needed irrigation, and then shut off. The owner checks the water level before running it. An automatic scheduled timer was ruled out because a) the plants might not need watering and b) it would be difficult to ensure that the pump wouldn’t run when the HOGs are dry.”

Thirsty U.S. Energy Production on Collision Course with Climate-Imperiled Water Supply

The “Water Constraints on Energy Production” produced by the Civil Society Institute (CSI) sounds the alarm for a significant collision between  thirsty energy production practices and an increasing beleaguered U.S. water supply.

The CSI report notes: “Currently, 97 percent of the nation’s electricity comes from thermoelectric or hydroelectric generators, which rely on vast quantities of water to produce electricity … Water is increasingly becoming a limiting factor on U.S. energy production and a key obstacle to maintaining both electricity output and public health and safety. The constraints range from insufficient water supplies to meet power plants’ cooling and pollution control needs—a challenge likely to be exacerbated by climate change, population growth, and competition from other sectors—to the high costs of energy-related water contamination and thermal pollution.”

We found this report, prepared by Synapse Energy Economics for the CSI, on the American Clean Energy Agenda site. Dive in for more info..

TEAM ASUNM Brings their SHADE Home to the Solar Decathlon 2013

After scoring high marks at The Solar Decathlon 2013 (and receiving 6th place in engineering), the takeaway for Team ASUNM is, not unexpectedly, increased confidence in their green building skills and knowledge. Through designing and building their net zero-energy home SHADE, the students of Arizona State University and the University of New Mexico have a hard-won knowledge and appreciation of innovative building techniques to  prepare them for careers as green building professionals.

Thanks for taking HOG along for the ride, Team ASUNM!

After the Solar Decathlon, SHADE will travel to Albuquerque and Santa Fe, where it will be showcased at the New Mexico state capitol for six months. It will then return to Phoenix, Arizona, where it will stay for three years as a part of the city’s Phoenix Renews development plan. The home will be a centrally located model for sustainable living in a developing neighborhood where other houses will be encouraged to go green.
