We will all agree, that when it comes to home operating costs and maintenance, little else burns as large a hole in our pockets as heating and cooling. HVAC is one place where homes lose a lot of greenery – in terms of money, and in terms of the carbon footprint they add. Therefore, when we remodel homes, a lot of homeowners want to know how to restructure their HVAC systems, to make their homes (and their pockets) greener. Our answer to them – mini split systems.
Most homes run on centralized HVAC systems that use ducts and sometimes pipes to control temperatures indoors. While these systems are quite alright, they are not always feasible when you are attempting a remodel, especially if you are adding an extra floor or room space or making major design changes. Restructuring the entire duct and pipe system adds considerably to the cost. Mini split systems make it easy to manage indoor temperatures without any major construction or uprooting.
Mini split systems are also called ductless systems and are available for heating and air conditioning purposes. These systems come with three parts, which can be very simply explained as: one part which is mounted indoors to maintain air and temperature, one part outside which handles the condensing and compressing and a third part linking both parts with suction wires, electrical wires, drain and refrigerant tubing. This entire system can be fitted with minimal inconvenience and construction and works efficiently to heat/cool/condition as per your requirements.
The amazing thing about them is their efficiency. Bonneville Power administration just did a study that found that mini splits can be as high as 450 % efficient. For every $1.00 you spend you get $4.50 worth of heat. Nothing else on the market even comes close. Back that up with a supper insulated house and your heating bill will become a non issue.

The ECO-Builders-Guild
South Sound Chapter
Presents
The South Sound Green Tour
Innovation – Education – Inspiration

April 17th and 18th, 2010

A community event to celebrate green innovations through education in sustainable building and inspired living.
This year’s tour will showcase the greenest homes and buildings in our area that incorporate significant use of solar or other renewable energies, new and reclaimed materials, low energy consumption and water conservation technologies, and sustainable design techniques.
Educational sessions will be held at various locations and feature real life topics on how to build and live greener. See our website for more details – www.SouthSoundGreenTour.com The site will be running by January 1, 2010

The Cooper project that we have been building will be one of many homes and businesses that will be open to the public for the weekend. Mark your calenders and join us, it should be a great time

The Northwest Eco Building Guild is an alliance of builders, designers, suppliers, homeowners, and partners concerned with ecological building in the Pacific Northwest.

A vital organization, our mission is to provide leadership in education to transform the built environment and build a sustainable society.

The main reason we’ve included LED in our recommendations, is because they’re quite eco-friendly, compared to all other options. LED produce much more light per watt of electricity. To be precise they produce around 18-22 lumens per watt, much higher than the incandescent and fluorescent lamps. This means they use less power to produce more, which cumulatively adds up to a lot of energy savings. In fact, the US DOE estimates that if LED lighting were used on a large scale, it would convert to savings of $265 billion, reduce electricity demand for lighting purposes by 33% ; and avoid the set up of 40 power plants across the country.
Also, every time you turn on the lights, you’re contributing to CO2 emissions to the tune of 196 pounds per year, for every light bulb in your house. LED lamps bring this to just 63 pounds every year. LED lighting is also non-toxic, it does not contain mercury like fluorescent lamps and thus recycling them is less hazardous. A few other benefits:
• LEDs are extremely small and are available in different colours. This goes well when you try to get creative with lighting in your house.
• LEDs can be dimmed quite easily. Repeated on-off cycles don’t damage LEDs the way they damage other lights. Thus, using LEDs for Christmas lighting is the ideal option
• They’re shock resistant, not fragile like usual bulbs.

Although not new, structural insulated panels (SIP) have recently garnered more attention than ever, thanks to the builders’, manufacturers’ and homeowners’ interest in green building and energy efficiency. With a view to energy efficiency, SIP is a good option. If you’ve ever been involved with any kind of construction in any way, you will notice that builders often use what look like large boards in place of conventional stick frames. Essentially, they’re replacing traditional house envelopes with SIP – and the best part about SIPs is that they can be used in place of any building material. SIPs are used in place of exterior walls, roofing material, floor boards and insulating the foundation.
The most obvious benefit of SIPs is that they have excellent insulating properties. A house built with one of the first ‘versions’ of SIPs in 1937 is still standing, after years of withstanding Wisconsin’s severe climate. The house was dedicated by then First Lady Eleanor Roosevelt and is currently used as a day care centre by the University of Wisconsin. Since then, SIPs have gone through many changes. The SIPs today play a significant role in reducing a house’s energy consumption requirements – particularly heating requirements, are quite low on maintenance and high on durability leading to lower operating costs and are easier and more efficient to construct. The only possible drawback that we might consider is their suitability over the long term in Northwest wet weather.

We had been looking for some beams to use on the living room and dining room ceilings and finally found some old growth beams in Seattle. The beams were originally installed in the Packard building, which was built in 1910, to house a Packard Auto dealership. From what we have learned, the building had at least two businesses occupy it during it’s 98 year life., the Packard car dealership and the Foley sign company. The building was torn down in 2008 to make way for new multi-use retail and residential building. A demolition company salvaged the lumber from the building and we were able to purchase a few of them.

As you might imagine, the beams needed a little work. We took them to Quality Solutions, a carpentry shop owned by Mike Anderson here in Olympia. Mike has the right equipment for cutting and planning large lumber like this. We started by cutting the beams down to the size we wanted, which was 8″ X 8” We then ran them through a planner to get all four sides smooth. From there we took them back to the house to finishes prepping them.

Using a hand power planner with a special curved blade, we proceeded to cut gouges into three sides of the beams. After that was completed, we sanded the beams with 60 grit and then again with 120 grit sandpaper. Then we coated them with a dark stain to contrast with the pine T&G boards we had already installed on the ceilings. After cutting the beams to fit between the walls and wedged them into place we crawled into the attic and secure them. We did this by laying 4X4’s across the top of the trusses bottom cords and then screwed ten inch long lags into the beams.

The end result is beautiful. It also fills good to know the beams have been given a new life ready to go for another 100 years.
