The Natural Spaces Domes Building System

The Natural Spaces Domes Building System is the only dome building system specifically adapted to the 5 different climatic regions of the United States. We are long time members and supporters of EEBA, The Energy and Environmental Building Association. Their innovative, well-respected building guides are backed by years of research in four nations: Canada, Norway, Sweden and the United States. The guides were created by Building Science Corporation, applying lessons learned from the construction of the Arkansas House, The Saskatchewan Conservation House and hundreds of houses built for Canada's R-2000 program and the U.S. Building America program.


Our involvement in over 1000 domes along with the EEBA guides has given us the information we need to adapt our dome system to the 5 major climatic regions:
Cold, Warm-Dry, Warm-Moist, Hot Humid and Marine Coastal.


Most other dome building companies ignore the differences in climate. Some even say you don't have to worry about condensation issues in colder climates. One competitor even says we don't know what we're talking about - all you have to do is install a heat exchanger and all your problems go away. How naive can you be! Back in the early 1980's we taught Energy Efficient Building Design 101 in the Minnesota State College System. But, we didn't say we knew it all. We built, we learned, we listened, we researched - and we used that information to adapt our dome building system, incorporating new technology and new materials.


In our 30+ years of building dome structures, we have learned
you shouldn't build the same structure in Minnesota as you
would in Houston, Texas.

Natural Spaces Domes started building a ventilated dome shell system in 1978, learning from 6 years of research, having built over two hundred fifty domes.

We saw problems with systems using materials that created vapor barriers on the exterior as well as the interior. Now we analyze climatic conditions and use "smart" vapor barriers or sometimes none at all.


We saw problems when bad building techniques were combined with waferboard, chipboard, OSB (Oriented Strandboard), Plystran and the like, allowing them to get wet. Now we only use plywood, 3/4" to 1-1/8" thick.


We saw problems using 2x4 or 2x6 construction limiting insulation thickness during a time when we needed to deal with the energy crisis and reduce our reliance on foreign oil. Now we use all types of insulation from fiberglass to recycled cotton to soft foam that uses American made soy bean oil.


We knew we wanted to drastically increase the energy efficiency of our dome so that it didn't meet just the minimum code requirement for 1979 (or even 2003). Now we build 15" to 21" thick dome shell systems with r-values from 44 to 71.


The following is an excerpt from the EEBA Builders Guide:

The three important changes in the way we build homes today interact with each other. This is further complicated by the effects of climate and occupant lifestyle. The interrelationship of all of these factors has led to major warranty problems that include health, safety, durability, comfort and affordability concerns. Problems are occurring despite the use of good materials and good workmanship.

We cannot return to constructing drafty building enclosures without thermal insulation, without consumer amenities, and with less efficient heating and air conditioning systems. The marketplace demands sophisticated, high performance buildings operated and maintained intelligently. As such, buildings must be treated as integrated systems that address health, safety, durability, comfort and affordability.

Quality construction consists of more than good materials and good workmanship. If you do the wrong thing with good materials and good workmanship, it is still wrong. You must do the right thing with good materials and good workmanship. The purpose of the EEBA guides are to promote the use of good materials and good workmanship in a systematic way, so that all the parts work together and promote good performance, durability, comfort, health and safety in an environmentally responsible manner.


At Natural Spaces Domes, the above excerpt serves as reinforcement to our basic philosophy - Solving building and environmental issues means we have to create advanced building systems while at the same time making the house healthy, comfortable and affordable for its occupants. A Natural Spaces Dome should be designed for the next century, not the last one.


Take a look at our dome building systems. Then talk to us about where you want to build, what you want to build and how you want to live. Our Natural Spaces Dome could make your dome dreams come true in a way you never imagined.
