Pono Home is a Honolulu-based startup offering to "green" your home, making it more energy- and water-efficient. It's an interesting idea. After all, many of us know what should be done, but how many of us get around to doing it?

Sometimes we just don't know where to start. Oftentimes we procrastinate.

Part of what Pono Home offers is the convenience as well as the expertise of knowing how to green your home.  And they do it for you. (I would be perfectly happy to have someone else clean out the refrigerator condenser coils).

I'm a green columnist, so of all people, you would think I know how to green a home.

Getting a solar photovoltaic system was a big step in that direction.  But having a solar PV system isn't an excuse to just hog up energy in your home, either. I don't know everything. And the water bill only seems to be going in one direction these days — up.

There are plenty of great resources on the web, as well as free workshops by Hawaii Energy. Even HECO gives you plenty of tips through guides like "101 Ways to Save" and "Cool Tips" as well as in its monthly newsletter. For a guide on what to look out for in household cleaners and beauty products, the Environmental Working Group publishes guides posted free online.

Here are a few tips I didn't know (from Pono Home's learning resources link for energy efficiency):

>> Did you know storing potatoes with an apple help reduce spoilage? Or that you should leave tomatoes at room temperature with the stem facing down?

>> Did you know that keeping the fridge and freezer two-thirds full results in a 5 to 10 percent reduction in electricity use? (from greenlivingideas.com)

>> It's best to turn off fans when not in the room. Fans only cool you, not the room.

Till the end of February, Pono Home, one of the startups selected by clean tech incubator Energy Excelerator has an indiegogo campaign that allows you to get the service while contributing $20 to an environmental non-profit of your choice, including SEEQS, the Blue Planet Foundation, Sustainable Coastlines Hawaii, and others.

Rid-a-Fridge, fight hunger

Rebates (and free pick up services) are available from Hawaii Energy for getting rid of your old fridge. You can also opt to donate your rebate to Hawaii Foodbank.

Get rid of your old fridge and help feed the hungry in Hawaii at the same time.

Hawaii Energy is offering a $25 rebate for Oahu residents who donate aging refrigerators with free pick up. On Maui and Hawaii island, Hawaii Energy is offering a $65 rebate.

By simply checking a box on the rebate application form, you can donate your rebate to the Hawaii Foodbank. The promotion continues while funding lasts. If you want to keep your rebate, of course, you may.

Replacing your old refrigerator with a newer, EnergyStar one can result in savings on your overall electricity bill (even if you have PV solar). Hawaii Energy estimates that fridges more than 20 years old can cost $275 to operate on Oahu each year. On Maui, because electricity rates are higher, they can cost $320 to operate each year. And on Hawaii island, $355 to operate each year.

On Oahu, call 537-5577 and on Maui and Hawaii island, call 1-877-231-8222 to schedule a free pickup. Afterwards, complete your application and send it in. If you'd like to donate your rebate, just check the "I'd like to make a difference" box. You will receive your application during pick up, which must be postmarked within 60 days.

The Green Homes at Lualualei just got a little greener, with the addition of native plants in late October.

Volunteers planted several native Hawaiian plants at the affordable housing project's landscape, including ‘akulikuli, naio and ‘ohai, following a special briefing by Rick Barboza of Hui Ku Maoli Ola. The plants were specifically selected because they are native to the leeward Oahu area and do well in its environment.

The Green Homes at Lualualei, by developer R.J. Martin, are equipped with solar photovoltaic systems, a water purification system and insulation to keep the heat out. The community offers 25 affordable homes in all, priced below the median average. The three- and four-bedroom homes range from about $250,000 to $350.000.

Last summer, two families moved into the community.

Let's hear it for brand-new, energy-efficient fridges on the Friendly Isle!

A total of 60 EnergyStar refrigerators were delivered to Molokai residents earlier this week as part of Hui UP! 3.0, an appliance exchange program offered through a partnership between Blue Planet Foundation, Hawaii Energy and Sust‘AINAble Moloka‘i.

Molokai residents were able to swap in their old fridges for a high-efficiency model for just $250, considerably less than retail prices. Pick up of old fridges, recycling and home delivery was included.

Francois Rogers, Blue Planet's special projects director, says the foundation is hoping to reach as many as 300 households on Molokai.

Sust‘AINAble Molokai helped with on-the-ground logistics, with help from Sears, Makoa Trucking, Island Movers and Refrigerant Recycling.

The Hui Up! program is a follow up to a CFL exchange program that replaced 36,000 incandescent bulbs on Molokai with Compact Fluorescent Lamps. As part of Hui Up! students from the Sust‘AINAble Molokai Youth Energy Team will visit the households and using hand-held energy monitors, they will measure the differences in energy usage.

Participants are expected to save an average of $374 a year (based on Molokai's electricity rate of 46 cents per kilowatt hour) on their individual electric bills. Collectively, over the next 10 years, 300 households would save more than $1.1 million in energy costs.

If you live on Molokai and are interested in participating in Hui UP!, visit blueplanetfoundation.org/huiup or call 560-5410.

The other day, I swung by the Re-use Hawaii warehouse to browse for recycled building materials.

photo[1]

The warehouse, at 200 Keawe St. (next door to the John A. Burns School of Medicine), first opened its doors in April 2010, and has since expanded.

Here, you can find everything from leftover, green tiles from the Wilson Tunnel to redwood lumber, windows, doors, cabinets, light chandeliers, drawer pulls, screws, hinges and even a few, occasional furniture pieces like a vintage office desk.

Cool, you could have a piece of the Wilson Tunnel in your kitchen or bathroom.

You can take a peek at what's available at this picasa link.

Re-use, a non-profit, specializes in deconstruction services, meaning it takes apart a home piece by piece, salvaging all reusable materials. It's a greener alternative  to demolition, which may be a quicker way to bring down a home, but ends up in the landfill.

The non-profit group has deconstructed hundreds of homes from Kahala to Kaimuki.

The warehouse also accepts tax-deductible donations of materials — but it's  best to check what they do or do not accept by calling or sending an email to info@reusehawaii.org first.

The last time I checked, they were accepting appliances less than 5 years old, screws, nuts, bolts, and tile measuring at least 25 square feet. They were not accepting cultured marble, aluminum sliding doors, hollow core slab doors, carpet or toilets. Glass, paint, office partitions, vinyl are also not accepted. Click here for more details.

Re-use Hawaii Warehouse is open from 8 a.m. to 6 p.m. Monday through Friday, and from 9 a.m. to 4 p.m. on Saturday. Visit reusehawaii.org or call 537-2228 to drop off donations.

Time to go solar

April 2nd, 2012

There's this Hawaiian Electric Co. commercial that ran at the start of the year, as part of a series of ads aiming to educate the public (and paid for with shareholder funds).

No, not the one where Jade Moon interviews HECO executive Robbie Alm. It's the one where Jade Moon interviews two HECO representatives — Ka‘iulani De Silva from education and consumer affairs and Blaine Cacho, an account manager.

The script goes something like this.

Jade Moon: "Does conservation really work?"

Ka‘iulani De Silva (smiling sympathetically): "We know high electricity costs are frustrating for our customers. But simple steps can amount to surprising savings."

"That's right," chimes in Blaine Cacho, matter-of-factly. "If you turn off the air-conditioner and let the tradewinds cool your home, you can save more than $1,000 a year."

While watching this commercial or whatever you call it, I found myself talking to the TV. "But we don't have any air-conditioning in this house! Not even a window unit!" I said.

Summers are sweltering in our house. We turn on fans and desperately open up all of the windows, wishing the tradewinds would flow through the house (if only it was built with the windows facing the right direction). The best solution seems to be an escape to the beach.

Our electricity bill currently averages about $200 a month, which is about $50 higher than it was a few years ago (along with everybody else's).

Then Jade asks Blaine about a second refrigerator and he says if it's a really old model, it could be using up plenty of energy. Removing it, he says, could also save you more than $1,000 a year.

"But we don't have a second fridge!" I said. We only have one fridge. It isn't fancy, but it's not one of the old models, either.

The HECO representatives, with pleasant, wanting-to-help smiles, dole out more tips. Washing your laundry in cold water can save more than $800 a year, adds De Silva.

"But we already wash in cold water!" I told the folks on T.V. "We've been doing that for years."

So seriously, what more can we do? HECO has a whole slew of publications with more energy-saving tips which you can find by clicking on "Energy Savings Toolkit." You have the "Power to Save" pamphlet as well as the "101 Ways to Save" brochure and the "Energy Tips & Choices" booklet. HECO does do a good job of putting out all these education pamphlets.

Still, our bill hasn't gone down much lately.

Did I mention that we already have a solar water heater and that we line-dry, too? Well, most of the time. On rainy days, we do resort to the dryer.

Lately, I've been walking around the house, flipping off the lights (yes, powered by energy-efficient compact fluorescents, mind you) and switching off various power strips at night, too. I bought an energy-saving "smart" power strip which keeps the DVD player from sucking out energy when it's not in use.

Since 2010, monthly bills have risen by 50 percent, says Alm, almost all of it due to oil. In the wake of the tsunami in Japan, oil has largely replaced nuclear energy, causing prices in the Asia Pacific region to skyrocket.

The cost of electricity is only going one way – up. You know what I think? I think it's time to go solar. The federal and state tax credits are still available, and there's still enough room in plenty of neighborhoods without HECO's concerns about destabilizing their circuits.

Do you know how much solar PV there is on your street? You can look it up on this map.

Stay tuned.

My Bokashi Bucket

February 20th, 2012
By



Here is my Bokashi Bucket, filled with apple, banana peels and rice.

Here is my Bokashi Bucket, filled with apple and banana peels, old rice and macaroni.

Since writing about Throw To Grow, I've decided to give the Bokashi Bucket a try.

The Bokashi Bucket, in case you haven't heard of it, is an anaerobic composting system that ferments your food waste (including meat, dairy and bones) into rich, gardening soil. It's basically a 5-gallon bucket tucked inside of another one with a spigot that you can keep indoors in your kitchen.

Each One Teach One Farms entrepreneur Jim DiCarlo sells the bucket systems at Haleiwa, Ala Moana and Hawaii Kai Farmers' Markets. You can also find them at Kale's Natural Foods and the North Shore Organic Gardening in Waialua.

If you're handy, you could probably pick up two buckets from Lowe's, Home Depot or City Mill and make the system yourself, except for the activator mix (basically bran mixed with molasses and microorganisms), which is a more involved process. Jim sells a jar of the mix for just $5 at farmers' markets.

What I like about it, so far, is that it seems easy to use.

I keep my bucket on a little step stool in the kitchen, next to the trash can. Once a day, or once every other day, you take your food scraps, open the lid up, toss them in and close the lid again. When the food scraps are at about three inches, you take your jar of bokashi activator mix (basically bran mixed with microorganisms and molasses) and sprinkle some on top.

I wouldn't say it's completely odorless. Hopefully I'm doing it right, but there is definitely a sort of sweet and sour, pickled smell every time I open up the bucket.

It's not pleasant, but it's not horribly unpleasant, either. My husband says he can tell every time I open the lid, because he gets a whiff, but it usually goes away after we turn on the kitchen ceiling fan for a few minutes.

So far, I've thrown all kinds of stuff in the bucket — orange peels, avocado and banana peels, apple cores, celery, ginger, egg shells, old pasta, old rice, a whole head of lettuce that went bad, a whole box of granola cereal (that some ants had gotten into), a whole rotisserie chicken carcass and salmon skin.

The word "bokashi" has turned into a verb in our household. Now I say, "Are you done with this? Should I bokashi it?"

My bucket is about half full, so far. When you open up the bucket, you won't see any transformation of the food yet. Apparently that happens after it all goes into the ground.

So far, so good.

Some things that are good to know: You want to only add fresh, not rotten (or moldy) food or it will smell. It's a good idea to place a paper or ceramic plate on top to basically compress all the air down. It's best also to keep the bucket away from sunlight.

For more tips on using the Bokashi Bucket, go to eachoneteachonefarms.com/bokashi.

We have a worm composting bin, as well, in the garage, and usually I put on gloves to open the lid, move aside the shredded paper, before tossing in food scraps. Separating the worms from the vermicompost is a messy chore in itself (I make my husband do it). What's nice about the worms is that you can throw moldy stuff in there. What I find challenging is that we usually have way more food scraps than the worms can process (since we just started with a small starter kit, which took a year to grow into a small bin). I often wonder whether it might be good to invest in  a Can-O-Worms system that can take more food waste.

The bucket doesn't take up a lot of space, but seems to be able to handle the volume. So far it's not too much of a hassle to throw the food scraps in there. My dog sniffs the bucket lid with interest every time I open it, but she's not too interested in digging through it (thank goodness). I can't wait to see how this all works once the bucket contents go into the ground. Will keep you posted.

Here's a cool video from Kasha Ho at Kanu Hawaii explaining how she tried out her Bokashi Bucket: Bokashi "Unbucketing" from Kasha Ho on Vimeo.

Another green home

Another green home has been built  on Oahu.

This one – a five-bedroom, two-story family home in Kaneohe — is the first in Hawaii to be certified at the gold level by the National Association of Home Builders (NAHB) Another home in Kailua achieved the bronze level.

It seems as if the list is growing.

The spacious, five-bedroom home replaces a single-story, three-bedroom home built in the 70s.

Mokulua Woodworking Ltd. built the home, in partnership with Archipelago Hawaii, which designed the home.

While partially deconstructing the home, Mokulua salvaged the beams for reuse and sorted out plastic, cardboard, and wood for recycling, as well as metal and wood scraps. The crew created only one 40-foot dumpster of waste, compared to the average of four to six dumpsters for a project of this size.

The Arakawa family (with three kids and a mother-in-law) live in the home. Owner Kenny Arakawa says when thinking about the new home, he wasn't necessarily interested in being "green," but that he knew a solar PV system made sense. But it turned out building green fit into the budget, which worked out well — and will result in long-term savings on energy and water.

Green features include: A custom-designed 4.8 kw solar PV system powered by 15 panels (installed by RevoluSun), LED-recessed lighting throughout the home, Energy Star appliances, pre-engineered structural  beams, and recycled trim, drywall and flooring. The driveway leading up to the home is terraced, allowing water to drain back into the earth instead of hitting concrete and flowing into the street.

The inside of the home features zero-VOC paint, laminate flooring made of 80 percent post consumer product, carpet with recycled fibers. It's been insulated with ecobatt, so it's also nice and cool.

Though there is split-air-conditioning, the family won't need to turn it on too often, with the breezes flowing throughout the home.

Mokulua Woodworking says it was able to frame the home using pre-engineered beams and trusses, which minimizes the number of lumber cuts needed for regular homes. Also, what I found interesting - its goal was to pour down the foundation as fast as possible (12 days) to minimize runoff.

Like the New Hawaiian Home in Kaimuki, there is a generous, covered lanai area which serves as an outdoor dining room, leading out to the yard.

The home is  Mokulua's first to be certified as green, although it says it's been building similar standards in other homes all along - getting the certification requires paperwork. Mokulua intends to build many more certified homes.

It's nice to see the trend is catching on in Hawaii.

A public open house showcasing green features of the gold-level home is scheduled for 10 a.m. to 3 p.m. on Saturday, July 30, 45-610 Huinawai Place. A $10 donation benefits Habitat for Humanity. You can talk-story with Mokulua, Archipelago and other contractors about how to build a certified green home, plus what tax benefits you can qualify for.

Jane and Jerry Mount are the lucky owners of the Green Playhouse.

The custom-built keiki playhouse, built by Pai‘ea Millwrights and Philip K. White & Associates, was auctioned off in May at Hawaii Nature Center's green gala.

The playhouse is made of recycled redwood, cedar, fir and luan. It's outfitted with a small photovoltaic panel on the roof to power a bubble blower on the composite Trex lanai. It also has a rain catchment bucket to help water the little WikiGarden.

It's a way to show keiki sustainable living.

"Hawaii is a place where we have the option to build very lightly and still have some comforts," said Logan Pai‘ea White, founder of Pai‘ea Millwrights. "Refinement can always be added through emphasis on design, functionality and creativity. The playhouse is a model of these values."

To win an award is one thing, but to see the real-life application of your hard work is a reward in itself.

Greenboy Design, a team of students from the University of Hawaii at Manoa's School of Architecture, is one of two finalists in the U.S. Green Building Council's 2010 Natural Talent Design Competition.

The team — which is made up of doctoral architecture students Frank Alsup, Sanphawat Jatupatwarangkul, Tuan Tran and Ramo Khem — will actually see their design for a single-family home built in New Orleans' historic Broadmoor district. The home is currently under construction.

The challenge was to create an affordable, energy-efficient home in a neighborhood under redevelopment. While incorporating green building principles, the team also maintained respect for the Broadmoor aesthetic, which won approval via a community vote held earlier this summer.

The 816-square-foot, two-bedroom home is on a challenging lot — narrow and rectangular.

Greenboy Design designed a contemporary, LEED Platinum home with an elevated deck surrounded by garden space and parking below. A covered patio becomes an extension of the interior living space, while the rear patio adds space to the master bedroom.

The team did a rigorous analysis of local wind patterns and daylight to figure out how to best bring natural ventilation and light into the home, added insulation beyond what was required, and planned landscaping that uses native ardisa for ground cover.

The design, of course, includes hurricane straps and tie downs, along with storm shutters for the windows that lock in place.

The team competed against more than 360 design submissions throughout the U.S. Final winners will be selected at Greenbuild's October conference in Toronto. More information about the 2010 Natural Talent Design Competition can be found at www.usgbchawaii.org.
