How Do We Choose a Passive Solar House Design?

The Small Home, Big Decisions series follows Jennifer and her husband, Tyler, as they build a self-reliant homestead on a piece of country property in northeastern Kansas. The series will delve into questions that arise during their building process and the decisions they make along the way. The posts are a work in progress, written as their home-building adventure unfolds.

After setting our house design priorities, Tyler and I discussed the easiest way to design our custom house. We thought about hiring an architect with a specialization in passive solar design, but ultimately heeded the sage advice of our contractor, Jeff Wooster, and started perusing online house plans. We were assigned to find some house plans that we liked that incorporated passive solar features, and then we’d have custom plans drawn with any modifications we had to the plans. Basically, by doing our best to incorporate passive solar design features, we would forgo a formal drawing session with a specialized architect — and forego the cost, too. (I promise to write a post about choosing a contractor, and also promise to write more posts about the continuing house-design process. It is a long, yet fun and important, conversation.)

Before we looked online, we needed some background in passive solar principles and environmentally conscious building materials and designs. We want to build an energy-efficient home, and also want to pay attention to the environmental footprint of the materials and building process.  So, we thumbed through several books and MOTHER EARTH NEWS articles:

    Making Better Buildings by Chris Magwood — Compares green-building techniques and materials, includes really useful charts to help you decide on the building type and process that will work best for you.
    The Solar House by Dan Chiras — A how-to guide to passive heating and cooling systems.
    The Sun-Inspired House by Debra Rucker Coleman — Specific information about passive solar and energy efficiency.
    Passive Solar Design Basics by David Wright — Just like it says, this article covers the basics of passive solar design.
    Passive Solar Design: Creating Sun-Inspired Homes by Megan E. Phelps — An interview with architect Debra Rucker Coleman about what to consider when building a passive-solar home.

Then, we turned to the best research tool we know: Google. I know, it doesn’t sound incredibly romantic or anything, but we Googled “passive solar house plans” and then “small home with open floor plan,” and found a surprising number of options. The plan we based our own home on most heavily is shown above, and we found it at The Plan Collection website, listed below. Many of the results were pretty worthless, but we ended up combining features from several plans that we liked from the following sites:

    America’s Best House Plans — Sounds silly, but you can search for “green” and “passive solar” designs.
    David Wright, Architect — A collection of plans (we liked the cabins page best) from the Solar Environmental Architecture Group.
    EPlans — You can do a quick or advanced search for various factors, including green features.
    Sun Plans — The tag line says it all: Sun-Inspired Design.
    The Plan Collection — Not specific to passive solar, but you can sort by size and style of floor plan.

Hi, I'm also in the home planning stage, well, dreaming stage I guess. I noticed in the plan you choose, your plumbing fixtures are as far apart as possible. Depending on where your water heater is, you'll waste a lot, trying to get hot water to each tap.The kitchen needs small amounts of hot water most frequently so locate the heater close. I think a plan with a central utility room, with kitchen, laundry and baths surrounding it would be more efficient. A room with open framing(easy access to plumbing and electric), that's large enough for future changes and maybe solar inverters,batteries. You can be almost certain there will be changes through the wonderful years to come. Good luck.
