Our first Open House Forum for 2005 is special in more than one way: first, it’s the first Forum we’re doing in collaboration with the TreePeople and second, it’s the long awaited opening of the home of Eco-Home™ Network Treasurer and Volunteer Coordinator, Jan Hoag, and her husband Ralph Zenger for an Open House Forum.

The home was built in 1921, with bedroom and dining room added in 1934. When Jan first saw it in October 1999, it was such a run-down fixer-upper that the realtor who showed it to her apologized afterwards, saying that if she had known what bad shape it was in she would never have shown it to her. What she didn’t know was that it was just the kind of challenge that would most excite Jan’s creative imagination.

By this time Jan had been a member of the Eco-Home™ Network for over 8 years and on the Board of Directors for 7, steeping herself in information about sustainble building and remodeling. She leapt at the chance to transform the humble little Altadena hideaway (only 950 sq. feet, plus detached guest room) into a small gem of eco-renovation. Occupied by Jan and Ralph and their two big dogs, Sam and Missy, it’s a shining example of minimizing the footprint of our buildings, a key principle in sustainable building.

Not that Jan or Ralph had heaps of money to invest in this project, but they had some, and Jan had watched the slow progress of the eco-renovation of the Eco-Home™ environmental demonstration home, and realized it took more knowledge and persistence than money to make a home sustainable.

After escrow closed in November and the place was hers, they proceeded, as time and funds allowed, to make the home more energy efficient with:

  • Wall insulation: cellulose insulation (processed recycled newspapers) was blown into the walls.
  • Ceiling insulation – ranging in R value from 13 to 18.
  • A radiant barrier in the attic. A radiant barrier is a reinforced heavy-duty aluminum foil sheet that is stapled to the roof rafters to reflect the summer heat, keeping the attic cooler.
  • A solar-powered attic fan, a gift from their solar installer, Wade Webb of SolarWebb, is mounted in the peak of the attic to blow hot air out of the attic through a screened vent. In the winter the fan is switched off to avoid heat loss.
  • Window film (owner-installed) on bedroom and office windows to reduce heat loss and one window in the living room that gets direct sunlight, to reduce solar heat gain.
  • Insulating honeycomb blinds in the bedroom and office windows for some insulation and a bamboo shade outside the living room which is lowered in the summer to keep from being blinded and/or baked. Preventing the heating solar rays from entering indoor space is more effective than blocking them after they have entered.
  • Insulating the water heater, which is outdoors, with a water heater blanket, and installing a a pre-made aluminum water heater shelter around it.
  • Wrapping the outdoor hot water pipes with insulating tape. (Note to other do-it-yourselfers: They first tried the pre-cut foam pipe insulation, but it kept coming off, possibly, they think, with the help of local wildlife.)
  • They knew from the beginning they wanted a whole house fan, and bought one on sale when Home Base went out of business, but for various logistical reasons it took a couple of years for it to get installed. What a difference!

A whole house fan is mounted in the attic, in an opening into the house. When turned on, the fan draws cooler outside air in through strategically opened windows (or even doors), into and through the house, and exhausts it out the attic. Obviously, for this to be effective, the air outside needs to be cooler than the air inside the house, which it generally is by the time they get home from work in the summer.

The other consideration is adequate venting in the attic, otherwise the motor will burn up. There is usually a chart on the box indicating the size of the fan, the size of the house it will work best for, and the attic ventilation needed. They got the smallest size available, and it is more than enough. Many homeowners install their fans themselves, and it’s not difficult, but, because of the oddness of their house and attic beams, they chose to hire someone who really knew what they were doing.

Jan and Ralph feel a definite improvement in the comfort level of the house both summer and winter after making all these energy efficiency improvements.

Floors
One of their first actions was to remove the old carpeting but so far financial constraints have blocked floor replacement, so they refinished the Douglas fir subfloor (a soft wood) with a water-based product. Initially, Jan and Ralph were very pleased with the result but it quickly started to show wear. Area rungs now cover a lot of the floor, adding aesthetic accents and warmth. Since this work was done, better water-based floor refinishes have come on the market, such as Street Shoe Basic and BioShield. (See references at end of article for more on water based floor finishes.)

They replaced the dirty old carpet covering the plywood subfloor in the detached guest room with carpeting made from recycled PET (soda) bottles. Jan remarks that it cleans up beautifully with a damp soapy cloth (or borrowed rug shampooer).

The kitchen floor is “real” linoleum obtained at Linoleum City in Hollywood where they have a large selection, and will do the installation. According to Jan, the hardest part was deciding on the color. “Ralph kept pleading color-blindness whenever the color issue came up,” she laughs. “I ended up walking around among the huge rolls of linoleum which were standing up like a forest, until one of them reached out and grabbed me (well, sort of).

“The dogs are able to run around on the linoleum without doing much noticeable damage, and it seems to clean up very well. The only problem is the few times I polish it with the Taski Vision Matte Acrylic floor polish provided by Linoleum City it looks great, but is too slippery for the poor dogs!”

The paint used indoors is zero VOC Frazee ”Envirocoat) and/or ICI “Lifemaster 2000”. The “Envirocoat”, used five years ago didn’t cover as well as the ICI paint, which they have used more recently.

Appliances
All the major appliances are “Energy Star”, including their Maytag “Neptune” washer and dryer.

Water Conservation
A graywater system delivers the washing machine water to the fruit trees in the back yard via delivery pipes buried below ground that terminate in a gravel bed around each tree. A valve at each tree allows for flow control. Ralph and Jan installed the graywater system themselves, with pipe, joints and valves from Home Depot (except the main one at the washer). Jan claims it was fairly easy to install. According to her, “The hardest part was finding the right valve to enable them to switch graywater water delivery back and forth from the yard, during most of the year, to the sewer, during the rainy season.”

The vegetable garden (which cannot legally be watered with graywater) has a drip system on a timer. Jan apologizes in advance for her failure to plant a winter garden this year because of other demands on her time. The Eco-Home™ Network Board of Directors and many friends, relatives, and business associates of Jan’s can testify to the fact that their summer vegetable garden can produce an over-abundance of excellent organic food, having been the pleased recipients of much of its excess production over the years.

Nexwood Compost Bins
Compost developed in the Nexwood compost bins and worm castings from a worm bin are added to the vegetable beds to nourish the plants . The garden border is Trex, which, like Nexwood, is a recycled plastic/wood fiber board that will not decompose in our lifetimes.

The front yard is all drought tolerant landscaping. Maintenance consists mainly of cutting things back occasionally and trying to get rid of the ivy planted by a former owner. A lemon tree manages to thrive on few, but deep, waterings. Mulch is used to conserve water in the soil and discourage weed growth.

Recycled Plastic Decking
Jan and Ralph rate their Nexwood deck their best investment in exterior improvements. Nexwood is a hollow core recycled plastic/wood fiber board that looks a lot like wood, but never needs the maintenance wood does. Greasy stains are cleaned up with Oxyclean. Water alone takes care of regular dirt. “The deck makes the house seem twice as big as it is!” Jan enthuses.

Leftover Nexwood boards from the deck building inspired them to build Nexwood compost bins. The bin design includes slats that slide out of the front and sides of the three bins so compost can be easily moved around. The greatest benefit of using this material for compost bins is that recycled plastic lumber won’t decompose, so they’ll last “forever”.

The Splurge
Jan admits that they splurged, energy-wise, on an (outdoor) spa. “I had always wanted one for soaking after a day of yard work and gardening, and had set money aside specifically for that purchase.”

She had assumed that gas heating would be more energy and financially efficient, but was convinced by the spa salespeople that with the insulation under the spa shell, and the insulated cover, an electric heater was more practical.

Waste water from the spa is used to irrigate various trees and flowers in the yard. The Baqua Spa chemicals used are bromine-free and chlorine-free and don’t seem to adversely affect the plants.

Alternative Energy
Jan and Ralph agree that the purchase and installation of photovoltaic panels were their hardest decision and biggest expenditure. They were concerned that the large trees shading the west end of the house might shade the roof too much for the panels to be effective. And they weren’t going to cut down the trees! Discussions with several solar installers at various Eco-Home Member Open Houses convinced them that a photovoltaic system was a viable option for them with minor trimming of only one tree!

Ralph came up with the idea of refinancing their mortgage while interest rates were low, and incorporating the cost of a photovoltaic system and installation into the new mortgage. They chose Wade Webb of Solar Webb as their installer. He is local, was recommended, had been in business over 10 years, and was a very small company – just he and a helper did the installation themselves. They were very pleased with their choice.

The total cost for the 2kW system was $19,000; with the $8,000 rebate obtained through Southern California Edison, the actual cost was $11,000. A state tax credit for that year of $1,670 brought their final cost down to $9,330!

Their “net metering” set-up allows the electric meter to run backwards when Jan and Ralph’s rooftop panels produce excess energy, above and beyond what they’re using. The excess goes into the utility-owned power lines to power other homes. The utility’s purchase of their excess energy appears as a credit on their energy bill which they receive only once a year!

“We had a good time that first year keeping track of our energy usage and watching our meter spin backwards (except when the spa was on!)” Jan remembers. Although she claims, “We’re not nearly so obsessed now,” she is quick to announce that even with the spa kept hot most of the time, their electric bill for one full year was $178.00! This bill will be on display at the Open House!

Still to do:

  • Replace the old double hung single pane windows with dual-paned windows of the same style. “We’ll certainly do so when we win the lottery!” Jan smiles.
  • Install an “on-demand” water heater for the bathroom, since it’s a bit of a distance (even in this tiny house) from the water heater to the bathroom. The challenge is to figure out how to do it without blocking access to the gas meter.
  • Insulate under the floors and install new floors in the dining room soon, possibly of used hardwood.

Jan and Ralph hope to see you all there, so don’t hesitate, call right now to register for the event, as we will be limiting attendance to 150 people and that includes our membership and TreePeople’s as well.
