Guests: Paul Hawken, Author, Blessed Unrest and Bill McKibben, Founder, 350.org.  Both these authors are well-established environmental activists. The presentation was conducted as a panel discussion with the moderator posing questions to the two. At the end there was audience participation. I thought it was a very interesting discussion on climate issues – both the politics and the science. Here is what I captured. In parenthesis I have introduced some of my own thinking:

• “Problem is that government policy has artificially increased consumption. There have been tax incentives for home ownership and government subsidies for freeways to get to all the homes. Thus, we have created a housing/work transportation design, which is very carbon-intensive (driving long distances) and now that carbon based fuels are expensive, it is an expensive design. Nevertheless, studies show people in cities have twice as many close friends as those in suburbia.
• Financial meltdown will take 10-12 years. (I have heard this before. It is not clear to me that without substantial changes to our economy that simply waiting will relieve our problems. The Great Depression was not relieved for 12 years until (more…)

When you are looking to spruce up your floors, there are several quick and easy updates that can increase your property value without causing you a lot of time and money. One of the main renovations that brings the best return on your investment is flooring.  If you are concerned of not being eco-friendly, you are in luck. There are a quite a few green flooring options available on the market that are pretty, durable, and that any future buyers will love.

Hardwood Floors

One eco-friendly alternative for hardwood is a salvaged wood floor. People are known to throw away old crates and barrels or to send to the dump remnants of older buildings like farmhouses. Instead, this wood can easily be cleaned, sanded and repurposed as a hardwood floor in your home. Once installed and sealed, these floors not only add character to your home, but they add the  beauty of the seasoned wood grain. Old wood can be found rather inexpensive at salvage yards.

Concrete

Most homes have a layer of concrete under their existing flooring. This concrete or a recently poured top can be turned into a great looking natural stone alternative. Etching and acid staining can color and seal the concrete into just about any shade desired. Concrete also works well installed over underfoot radiant heating systems.

Bamboo

Bamboo is great for floors. Depending on the way the graining lays, bamboo flooring can look just like wood floors, or it can have a neat textured or patterned feel. They are hard and resilient, and bamboo is grown like wheat, quickly in a short amount of time. Bamboo is also mildew-, mold-, bacteria- and water-resistant.  Make sure to look into the VOC levels of the bamboo floor and opt for the lowest possible, no need for breathing fumes from an “eco friendly’ product.

Cork

Cork is normally seen in bottles and as bulletin boards or sign hanging places on walls. Cork is designed to be resistant to mildew, bacteria, and mold. It also naturally repels moisture. The best part is cork floor is soft and warm on bare feet, which makes getting up in the morning a little easier and oh so pleasant.

Glass Tiles

Glass tiles make great floors. They are hardy and durable. They can be very slick, but texturing makes them less slippery. Many glass tiles are made from recycled materials, including bottles and jars. Just look for recycled written on the packaging.  Glass tiles make a beautiful, green choice.

Cork, bamboo, glass tiles, concrete, and salvaged wood are great eco-friendly flooring options. These are easily installed, and when you are selling your home, buyers will love the looks of them. Whichever flooring option you use, these environmentally friendly choices will add value to your home.

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…)

After World War II, houses and buildings were erected quickly and cheaply as a means to rebuild Germany. However, many people living and working in these houses and buildings soon became noticeably ill, with all signs pointing to the new buildings as the cause. It was this phenomenon that inspired the baubiologie movement in Germany, and has since been infused in other parts of the world as well. Below are the 25 principles of baubiologie.

1. Building site without natural and human-made disturbances
2. Residential homes away from sources of emissions and noise
3. Low-density housing with sufficient green space
4. Personalized, natural, human- and family-oriented housing and settlements
5. Building without causing social burdens
6. Natural and unadulterated building materials
7. Natural regulation of indoor air humidity through humidity-buffering materials
8. Low total moisture content of a new building that dries out quickly
9. Well-balanced ratio between thermal insulation and heat retention
10. Optimal air and surface temperatures
11. Good indoor air quality through natural ventilation
12. Heating system based on radiant heat
13. Natural conditions of light, lighting and color (more…)

Solar energy, more commonly defined by the energy geeks as “radiant light and heat from the sun”, continues to be harnessed for energy production. As you may be aware, most accountable renewable energy invokes the following:

• Solar Radiation
• Wind Power
• Wave Power
• Hydroelectricity
• Biomass

The problem is, only a fraction of the radiation gathered from the sun is really used.

Scientists have always used both light and heat from the sun to produce energy, however, they hadn’t yet discovered a way to efficiently utilize both simultaneously – Until now!  A device out of Stanford University is promising not just one production of the solar energy but two by being able to harness the power of both light and heat.

A Photon Enhanced Thermionic Emission device, or PETE device, is not only a state of the art technology but could potentially reduce the costs for the production of solar power to the point of where it could be a real competitor against oil as a source of energy. This is great for two reasons: 1) the environmental aspect of having solar power being a big player in the energy game is huge considering that it’s a renewable and clean energy source and 2) therein lies a real competitor to the oil industry. This is not to mention it also could open the door to (more…)

So you’ve heard about it, with the passing of PACE (Property Assessed Clean Energy) , many homeowners, municipalities and home performance contractors had great expectations of easy and accessible financing for energy efficiency and renewable energy installations.  However, something happened…  Call it a glitch but PACE, as of today, is still not available.  There is a solution though.  Keep reading… 

An innovative tool for financing, PACE provided a solution to declining home values in much of the nation by offering financing that the homeowner repaid as a tax assessment rather than a mortgage lien.  PACE Programs were active or soon to be implemented in California and 22 other states.  

However, the Federal Housing Finance Agency (FHFA) that regulates Freddie Mac and Fannie Mae, declared that the PACE programs presented “significant safety and soundness concerns” to the housing finance industry on July 6, 2010.  This declaration closed the door on PACE funding.  Even though legislation and lawsuits are still pending against the FHFA, no funding is expected to be available before the end of the year from any PACE program.  Talk about taking the wind out of one’s sails. 

Although PACE funding is now unavailable homeowners still have many options. There are many (more…)

Did we even need to drill the Deepwater Horizon oil well to begin with?  Actually, no. There are over 100 million homes in the U.S. Most of them use energy inefficiently because they’re not well insulated, sealed and set up.  The energy contained in the biggest oil spill in U.S. history is equal to the energy that just 75,000 homes waste in a single year.

Seventy-five thousand homes represent less than 0.1 percent of all single-family homes in the U.S. or the number of homes in a single mid-sized U.S. city, like Providence, R.I., or Chattanooga, Tenn. Doing energy retrofits to make those homes efficient would save the equivalent of the entire Gulf Oil Spill every year on a permanent basis.

Comparing the Costs

No one really knows how much it’ll end up costing to clean up the disaster created by the Gulf Oil Spill. And when a final number is calculated, years from now, there’s no way that it’ll take into account the true extent of the environmental damage that the oil spill has created. But even in the preliminary estimates made before the oil has finished flowing, the cost is expected to exceed $40 billion.

How does that compare to doing 75,000 home energy retrofits? (more…)

First off, a few burning questions… Have high upfront costs derailed your renewable energy or energy efficiency projects? Would receiving positive cash flow from day one make your clean energy project more attractive? Are you worried that it may be difficult to recoup your investment in clean energy if you sell your property?

To resolve these issues and accelerate the implementation of energy upgrades to commercial and residential property, cities and counties across the nation are offering PACE, a new financing model for clean energy projects.

To learn more about how PACE works and how it can benefit businesses and homeowners, I recently spoke with Dennis Tsu, who manages Business Development for Commercial PACE with Renewable Funding. Based in Oakland, Renewable Funding is the leader in the turnkey administration of PACE programs.

What is PACE?

William Dinkel: Could you please provide a brief summary of PACE programs for our readers?

Dennis Tsu: First off, PACE is an acronym for Property Assessed Clean Energy. The basic concept is to allow residential and commercial property owners to borrow money from their local governments to use for making energy efficiency or alternative energy improvements to their properties, and then to pay that money back through a (more…)

A small bungalow front yard is reborn as a shady woodland oasis of natives centered by a naturalistic fountain accented with metal sculpture.  As you’ll read on, you’ll notice from the photo tour that this new garden shows that sustainable landscaping can be accomplished through DIY talent and on a shoe-string budget when working closely with a professional landscape designer.

The home owners of this Craftsman style home in College Park area of San Jose already prided themselves living a green and sustainable life style.  But there was still some unfinished business – their water thirsty lawn.  So they decided to say goodbye to their front lawn and concrete hardscape and figure out a way to design a new, water wise yard on a budget.  They were receptive to many sustainable suggestions including: turf rebate programs, lawn removal, water-wise irrigation, flagstone installation, planting natives and storm water management.

Fact is, if you have the time, patience and willing to learn, you can do a lot on your own.  Here is what I mean… Size of the lawn was 900 square feet.  For about $5 a square foot, I designed the plans and coached my clients through their installation.  They did the install themselves but I helped them locate materials and assisted them in receiving an $800 water rebate by removing their lawn.  Total cost?  (more…)

So Mary, how does it grow?  With wisely planted trees and shrubs, and many sunny days without rain in a row.  It’s called water-wise gardening my friends. 

Did you know an average Bay Area home uses almost 80% of its total potable water for simply watering the lawn and plants?  What would you say if you found out you can have a glorious looking landscape by spilling a drop instead of a bucket to water it?  Just imagine the water savings and your water bill at the end of the month.  In fact, read on and I’ll tell you where you can get a $1000 rebate for going water-wise! 

Don’t be afraid, “sustainable” landscaping doesn’t mean rocks and once a year blooming cactus. By understanding our climate zone, soil type, sun and shade conditions, and the water requirements of your site, you can have lush and beautiful garden if you practice some fundamental principles of water conservation. 

Why Landscape to Conserve Water? 

Drought is a part of the natural weather cycle of the West. Even though we have been able to import water from other areas, our population is rapidly outgrowing existing water supplies. In the years ahead, water conservation and water-wise landscaping will need to become a part of every westerner’s lifestyle. 

Use water conserving plants: The key is to choose plants that are (more…)
