Low Impact Development Demonstration.
Minimalist open air house design by Joachim Hagemann

Hawaiian based company Green Architectural Design created this open air 40x40 Hawaiian inspired pavilion. Made out of wood it is reminiscent of the kind of Hawaiian building frequently seen in the country side. It has a glass structure that affords an unimpeded view. Modular spaces can be expanded. Sliding doors on all sides give the impression of being an extension to living space

Hybrid Solar Air System

We understand that for most people, solar power is a mystery, therefore, it is our goal to provide the best information possible about our systems and how they can benefit the "everyday" user.

System storage requirements:

How much storage, in amp-hours, do you need? This will vary with the application and what part of the country you are in. As a rough rule for home solar systems, the total battery capacity (in amp-hours) should be three to five times your daily usage. 3 days is usually sufficient in most of the sunbelt states, 4 in most of the Midwest, in the East and Northwest, 4 to 5 days is better. If you are in a good wind area and have a wind generator, you can probably cut this down a day, but wind turbine output can be highly variable in many areas.

For backup power systems (UPS), the total capacity should be enough to cover about twice the longest anticipated outage. To figure how many amp-hours storage you need, take your average daily usage in watts and divide by the battery voltage. For example, if you use 5 kwh (kilowatt-hours) per day, and have a 48 volt system, then dividing 5000 by 48 gives you 105 AH. Since you do not want to discharge the battery more than 50% in most cases, you would need 210 AH. If you want to keep running for 4 days of bad weather with no sun, multiply that times 4, which gives you about 850 AH total capacity. UPS and backup power systems are the same, except that the times are often in hours instead of days.

How many Watt-Hours in a battery?: Watts are pretty simple - it is just battery voltage times amp-hours. A 12 volt 105 AH battery can supply (under perfect conditions and to 100% discharge) 12 x 105, or 1260 Watt-hours (1.26KWH).

The System may also be expanded by connecting extra batteries or extra systems to the post-terminals using jumper-cables. By “jumping” extra batteries the batteries capacity is increased, allowing for greater power storage.

The formula for finding wattage is very simple.

Watts = Volts x Amps


So lets say you have a 1000 watt stero system in your car. You wanna know how many amps that its sucking down.

Amps = Watts / Volts

Since a car battery is 12 volts: 1000W / 12V = 83.3 Amps.


Ok now lets say Uncle Jimbo has put in a 30 Amp breaker for his massive year round Christmas light display that his neighbors are threatening to sue him over. You want to find out how many watts of lights that Jimbo can put up before it blows the breaker.

Watts = Amps x Volts

Since house current is 120 volts: 30A x 120V = 3600 Watts or 3.6 Kilowatts
(Yipes Jimbo!)


Lets say a PSU puts out 17 amps and 204 watts on a certain rail. You want to find the voltage.

Volts = Watts / Amps

So 204W / 17A = 12 Volts.

Flexible Portable Power Generator. 5 minute set up time, 2 cases USD 4990.00

American made - The System is produced from as much American-sourced product and materials as is possible. Our buyers vigorously research the market landscape to find the best product from domestic companies, even though it often results in higher costs than imported materials.

Quality - American Made Products are often of higher quality than inexpensive imports, guaranteeing our customers a superior product,there is no "planned obsolescence" built into our system, and very little maintenance necessary to keep it functional.

Do I need a permit to use a Solar System at my house? It is a portable solar generator that does not require any approvals for use. It is a self-contained, turn-key system that is ready to operate right out of the box. Are there any Tax-Rebates or government incentives ? The answer to this question lies in the state in which you live. There is a great website that can be accessed by clicking here that has a plethora of information on it regarding State & Federal programs. OPERATION: How many persons does it take to setup a system? In most cases just one, and it is designed to be erected and functioning in less than five minutes. Disassembly is also less than five minutes by one person. Can I use it to power our house? The unit is a portable DC power generator, and not designed for direct connection to your home's AC electrical system without a grid-tie inverter. You could, however, power select appliances in your home using the system. For example, you could operate a refrigerator, television, radio, computer, and other devices.

Green design results in savings of total construction cost, an initial upfront investment of 100k in green building features on a 5 million project would result in 1 million savings over the life of the building.

New Project on Hamakua Coast

The new project is up country on the Hamakua Coast near the town of Pauillo. The site is on the side of valley that funnels up the ocean winds into the foothills of Mauna Kea. The house will look out, down the valley, to the ocean. It's beautifully quiet cattle country.

The design is based on a Kaloli 2 with an enlarged deck and built on a slab. The house will take advantage of the breezes coming up the valley with energy efficient sliding doors. The doors will also contribute to the daylighting of the house, reducing the need for electrical lighting.

The area had been bulldozed and we were supposed to be putting together the forms for pouring the concrete slab.

(Picture by Rachel Baddorf Copyright 2010)

We measured using a laser level and found that the surface wasn't even enough yet for a good slab. The bulldozer needed to be called in to go deeper for an even grade.

The project is underway and progressing.

Portable Power Generation will never be the same…

Our new system for the Kaloli 4.

The System has two axes of rotation that allow for maximum solar panel power production. The panels can be rotated on a horizontal and a vertical axis. It DOES NOT have the third axis that allows for the panels to be folded down against the Mast during inclement weather.

Three daily panel adjustments (aiming the panels at the sun) will yield a tremendous power gain over a static position.
The system employs a100 Watt solar panel systems, and the average maximum daily power production for the System is usually about one Kilowatt-hour, but depending on location and conditions, may occasionally exceed 1.2 Kilowatt-hours.
Once fully assembled,it weighs about 60 lbs. The construction is primarily T6061 Aluminum (aircraft-grade) and stainless steel. There are no tools required for assembly, and every removable component is leashed to prevent loss. The system can be used in the harshest of environments, and deployed for an hour or a week without regard for the weather.
It has a 5 year limited warranty on materials and workmanship and a 25 year power output warranty.
Both Systems are made in the U.S.A.
All systems are Field-Serviceable, and require very little maintenance and can be set up in a couple of minutes

Designed specifically for Recreational, Humanitarian, Residential & other "Light Duty" Applications...
...at 40% less cost!!

...and unlike many of our competitors,
it is Made in America!

A Sustainable building, or Green building is an outcome of a design which focuses on increasing the efficiency of resource use — energy, water, and materials — while reducing building impacts on human health and the environment during the building's lifecycle, through better siting, design, construction, operation, maintenance, and removal.
Green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment by:
Efficiently using energy, water, and other resources.
