However, without the proper knowledge, searching for a portable air conditioner can become an overwhelming experience. Between trying to figure out a plethora of acronyms like EER and BTU and wading through numbers all over the 1,000s, the confusion can multiply. But, with a basic foundation, a confusing and/or time consuming experience can quickly become a simple formula that leaves you lingering in the comfort and bliss of a perfectly cooled and de-humidified room.  And not only that, purchasing the right AC, the first time, will save you now and over the long run.

Basic AC Terms

“W”  – A “W” is a watt, which is the standard unit for measuring power.

“BTU” -  A BTU stands for British Thermal Unit and measures thermal heat energy. In terms of ACs, they will generally rank in the 1000s.

“EER” – EER stands for the Energy Efficiency Ratio of any given appliance and basically tell you exactly how much cooling your AC will be able to provide you based on the amount of electricity it’s using. The higher the EER rating, the less energy it consumes. As a basic rule, anything over 10 is deemed “good” in terms of energy efficiency.

You will often see “energy consumed” represented by a “W,” and EERs can also be listed as BTU/W.

This means if you (more…)

If you had to imagine the greenest home in California, what images would spring to mind?  Would it be some clay, dome shaped structure perfectly exposed to solar angles, or maybe an ultra chic, boxy looking modern beauty with massive windows facing a valley?  What if I told you that this home sits on a pretty standard residential street in Santa Clara and an untrained eye wouldn’t even notice any “greenness” about it if they drove by?

Meet the “Bluebird” residence.  This Earth Bound Home’s show house  is also the personal residence of founder David Edwards.  Rated as the Greenest Home in California by Build it Green organization, the original 1400 sq. ft. ranch style home was added to and remodeled, creating a 3100 sq. ft. 4 bedroom, 3 bath home with an office and workout room.   Awards range from Acterra’s Business Environmental Awards Built Environment Award to Build It Green’s South Bay Best New Home award for the 1996 Green Home Tour. Come with us on a video tour to explore all the ingenuity, design and careful choice of materials that went into this project.  (Also see a list of “green” features below the video.)

This home’s many green features include:

• Small 2.7 kw Photovoltaic solar electric panels provide all of houses electrical needs
• Solar thermal renewable energy systems
• An inexpensive and no maintenance Grey water system waters the only plants in the entire landscaping that require water, the clumping Bamboo.
• A 1400 gallon underground rainwater cistern collects rainwater every winter
• All FSC wood framing and FSC certified Brazilian Cherry Flooring
• Home built with Structural Insulated Panels(SIPs)
• 65% more efficient than Californias’ Title-24 Energy Efficiency requirements
• $155/year gas bill, $4/year electric bill, $132/year water bill
• 93%  recycling and reuse of building demolition debris
• Half of all windows were purchased from salvage yards, saving over $10,000 over new windows
• All doors on the first floor were salvaged, saving $3,000.
• All trim throughout the house was salvaged from old redwood decks, fences and the siding on old houses. It was milled on site and the shavings used as mulch on the landscaping.
• New One Lawn Synthetic Lawn contains no heavy metals and requires no maintenance or water. None of the landscape requires supplemental water and saves approx. 50,000 gallons of water a year.
• House uses 31,285 gallons of water a year, for 5 people. This is approx 84% less. than the average household uses(~110 gallons per person/day- including irrigation)

When most people think “green” homes they imagine solar panels and fancy energy saving gadgets.  It doesn’t have to be this way.  We invite you to explore with us a passive solar home in Saratoga (Bay Area) designed by a local architect Hari Sripadanna.  The home has achieved a LEED Gold rating and truly stands as a model for sustainability in our community.  After all, Hari bought parts of his house on Craigslist! 

Obviously, we could not cover all the fascinating details in the video so if you want to learn more, please read Hari’s comments and see design plans right below the video.  Enjoy.

by Hari Saripadanna (parts of the article was originally posted on the GAB Report):

With increasing popularity of green building and passive solar design, it is important to understand that sustainable design is more than a collection of credits. The key is to create synergy between building systems and practices that multiply each other’s benefit. One can create more value simply by choosing two or more complimentary sustainable design elements that play off of each other. The combined effect is more than the benefit when these design elements or systems are used alone. 

I would like to share with you some synergistic concepts used in the design of my house and show you how (more…)

In a market where hardly anyone is building green in San Jose, this newly constructed house in Milpitas area stands as a monument of energy efficiency and inspiration.  

It is about 35% more energy efficient than a standard home and prides itself on green elements like engineered lumber, radiant barrier roof, solar water heater, energy star furnace, extra thick insulation, excellent indoor air quality and much more.  

Come with us on a video tour and discover for yourself what makes this property truly unique.

This beauty is a five year project by Green Earth Construction, a Milpitas based and family run company.  Sylvia Leung and her husband had a vision to go green 15 years ago and are finally able to marvel at the fruits of their labor.  In addition to what you’ve seen on the video, keep in mind that the home is wired for solar and if one decided to invest into solar panels, one’s utility bills for the most part of the year could be virtually zero.  Now that’s a good number, isn’t it? 

Building green normally commands higher costs so perhaps the most pleasant detail about this home is that when considering a dollar per square foot basis, the home is priced comparably to a 25 year old home.  If you like more details, you can find all the info under Featured Listings on http://GreenHomeParter.com.  Feel free to contact me directly with any questions. 

We all know by now that toxins in our home can affect our general health but did you know that flame retardants in the house can lower your chances to have kids?  If you are a male then pay attention.  And if you are a female who has a male than also pay attention…  Recent studies show that flame retardants, found in 96% of all house dust, can seriously lower a male’s chances of being a fertile stud.  

Surprisingly, flame retardants are found in furniture padding, draperies, electronics equipment and plastics.  These flame retardants end up in dust and then inside of us.  

Flame retardants using PBDE (polybrominated biphenyl ether) were phased out in 2004 because of their hormone altering or endocrine disturber effects.  Instead of PBDE, the industry has gradually upped the use of the organophosphate based flame retardants, TDCPP (tris (1,3-dichloro-2-propyl) phosphate) and TPP (triphenyl phosphate).  The problem is, they still may also have hormone altering effects. 

A lot of our concern has been about levels of endocrine disturbers in pregnant women and resulting hormonal problems in infants and children. But what about getting pregnant in the first place?  Is there something going on with the male contribution side of things? Why have male testosterone levels and semen quality seen a downward trend?  Very likely that part of the reason is (more…)

Let’s face it, no home is truly green without supporting the health of its inhabitants.  With a rise of cases where more and more people, and especially our children, are developing allergies, asthma, and chemical sensitivities, many are looking for solutions in the the quality of their indoor air as never before. 

Want to hear some awesome news?  We have an abundance of options to keep our in-home air as fresh as the Amazon rain forest.  OK ok, maybe not like the Amazon, but close.  Come with us on a tour of non-toxic and sustainable materials to learn some things you can do to give your lungs a break that they deserve.

Some say that remodeling green is an incredibly joyful adventure.  Some feel that planning, choosing, and fighting with one’s spouse over the colors and materials is more painful than waxing ears.  Whatever your position is, these tips will make your experience more enjoyable.  Most of this advice comes from experience or friends in the community.  

When remodeling green, avoid making these mistakes: 

1.  Getting excited about eco-chic materials first and busting your budget.  It’s hard to resist starting with items like recycled glass countertops  or FSC  certified cabinets but do focus on upgrading you home’s energy efficiency first.  Start with things like water tightening you walls, insulation, windows, furnace and solar water heater.  If you have money left, go for the updates that make your nest more fun and cozy.

2.  Going overboard on upgrades for the neighborhood.  Significantly over-improving only feels good until you’re trying to sell your home.  If you only knew how often an overpriced home simply sits on the market because the homeowners are trying to recoup their fortune that they spent on remodeling…  Depending on the price range, few buyers will likely pay extra $30,000 – $50,000 above neighborhood market price, even if your home is a model of energy efficiency.

3.  Failing to take a holistic approach.  Often, when you change your home’s one component, it affects all others.  For example, (more…)

Hello, is anyone home?

“There’s a sound outside the front door… And I know it’s just the wind… But it makes her snuggle up just a little bit closer… And it starts things happening again… 

Steamy windows — zero visibility… Steamy windows — coming from the body heat… Steamy windows –  Steamy windows.“ 

No, this is not a new poem conjured up by a drunk Realtor over the weekend, it’s a Tina Turner song .  Remember it?  Actually, if you’ve heard it enough times it will spontaneously start playing in your mind upon the sight of steamy windows.  That’s what happened to me while walking the neighborhood the other night.  I noticed very steamy windows of the house, just dripping with moisture.  Now if it was just a bedroom window, then hey, good for them, right?  Normally, that steam will be gone in 15 minutes anyways.  But when you see this in the living room window, candles lit, fireplace burning, pot cooking you can’t help not to wonder – how can they possibly enjoy breathing that stuff?   

Actually, it seems that with all the focus on energy efficiency many times we miss the most important issue of it all – Indoor Air Quality (IAQ).  Not only it directly affects our health, we can not have a truly green home without addressing the air that we breathe inside.  

EPA says our homes are actually packed with pollutants.  Some pollutants cause health problems such as (more…)
