The Eco Builders Guild \ South Sound Chapter has announced it will host the South Sound Green Tour on April 17th and 18th, 2010
The theme of the event will be Innovation – Education – Inspiration

It will be 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 should be up and running by January 1, 2010

South Sound Green Tour is looking for participants and sponsors. If you are interested in either contact me at info@laupenhomes.com. After January we you will be able to contact us directly at SouthSoundGreenTour.com

Quite frankly, it is not to much effort. Building technology has developed to a great extent since the passivhaus standard came into existence, and it is quite a bit easier to build a passive house now than it was 10 years ago. Most of the building material that you require are easily available. Passive houses are as comfortable to live in as any other homes and in fact are healthier and safer because of the building design.

Passive houses are more expensive to build than conventional homes because of the materials required between five and ten percent depending on size. However, over the long run, they have proven to be much cheaper. When you look at how much a conventional home costs in terms of heating, cooling, ventilating, electricity, and air conditioning – a passive house turns out to be a cheaper bargain.

Passive homes are not that uncommon either. Although it is difficult to find a completely passive house in the US – they’re common in the UK and across Europe. Closer to home, we have green homes that make use of some of the principles of passivhaus and add their own two bits to create an energy efficient green home. In Washington DC, we have architect and green builder Travis Price’s four story green home, just about 10 minutes from the White House. His house was featured on the Discovery channel’s World’s Greenest Homes – which, by the way, is a great show to see how much and how easily people can build green homes for themselves.

When you approach an eco-friendly contractor to build you an eco-friendly home one of the things he Is going to suggest (and carry out too) is the switch to solar electricity. Depending on your requirement, resources and the location, there are quite a few options you have when it comes to using solar electricity: You could install solar panels to generate total or partial capacity or you could buy it directly from your provider.

Your contractor will suggest that installing solar panels will be the most effective way to turn your home green. A better contractor, however, will suggest ways to make the best of the ambient sunlight you have for lighting purposes, so that you’re now powering other electrical appliances with solar electricity, and not so much the lights. This can be done by the Passivhaus standard which will entail constructing the home in such a manner that most of your rooms are lit up with natural sunlight, while ensuring that it doesn’t heat up the house unnecessarily.

The other things you want to discuss are appliances that save electricity: EPA certified one, CFLs, and the latest – LED lamps. Also, it is very important to ensure that you and the contractor carry out an energy audit of your existing house first in order to compare the savings your new house will generate.

Many of our customers want to shift to solar energy, but find the investment in a solar electric system too heavy. For such individuals, we often recommend going for solar water heaters to take care of the water heating requirements. This is relatively cheaper and easier to install, so you can save the environment and some cash too.

There is a basic difference between solar electric systems and a solar water heater. The former use the light energy of the sun and the latter, use heat energy. Thus, solar water heaters come sans the PV modules but with a solar collector which traps heat instead of light. There are 5 types of solar heaters available in the market:
1. Batch systems: For a 1-2 person household, low cost, temperate climate (not very cold winters), simple.
2. Thermosyphon systems: Passive solar system with no moving parts, suitable for temperate climate, less efficient and more expensive than active solar systems but very reliable, obtrusive in appearance. Fit for 3-4 person household.
3. Open-loop Direct Systems: Active solar system, the most simple of systems, heats domestic water directly in a storage tank, works well in temperate climates
4. Pressurized Glycol Systems: Closed loop system which heats up a non-freezing fluid and uses this fluid to heat up the water, suitable for regions with freezing temperatures,
5. Closed Loop Drainback system: Requires minimum maintenance, Works on similar principle as above, distilled water used as the heat transfer fluid.

Solar water heaters make a lot of financial sense and will drop your electricity bills or heating bills by almost 50%-80%. Add to this tax rebates and credits that you’re entitled to on purchase of a solar heater and the overall cost is reduced by a huge number.

Using solar energy in any form in your house contributes in many ways to preserving and bettering the environment, and also the quality of indoor air and the home itself. With the way the environment is going down and fossil fuel prices are going up, energy efficient homes are the only kind of homes that can sustain in the 21st century and beyond.
Therefore, be it solar water heaters, lamps or an entire solar electric system – solar energy is an important step and consideration in making your home energy efficient.

Often though, creating a completely energy efficient requires extensive remodeling, in order to take care of heating, cooling, lighting, plumbing, insulation, electrical appliances and other things. This may not be feasible for everyone, and sure enough, isn’t, for many of our customers. Therefore we generally suggest homeowners who want to shift to an energy efficient to start by just adding solar panels, and a simple solar electric system. This takes a lot of burden off the environment and also your own budget in a threefold manner:

1. You are no longer using electricity produced fossil fuels to power your home (which is not very energy efficient either)
2. Although your home is still inefficient when it comes to energy, at least you’re using clean, renewable and home-made energy to power it.
3. You’re taking some measures to introduce energy efficiency without burning a hole in your pocket.
