Zero Energy Buildings
Structures To Go, a Structural Insulated Panel (SIP) manufacturer in Port Angeles, WA, provides building kits and completed buildings.  Visit  The company has manufactured and delivered dozens of these strong, energy efficient buildings.  Read about their debut in the Fall 2005 Olympic RE News.

This "pop up" building can be erected in less than 30 minutes, deployable with a roll-deck truck to anywhere anytime.  A compartment below the roof stores emergency supplies, lifting poles, trim pieces, and other hardware used in placing this building in a temporary field application for emergency management.  [see left]

The Port Townsend office of Olympic Energy Systems has occupied this SIP building for over a year.  The annual electrical energy usage of this 8 x 12 building can be met with a 1200 Watt grid-tied solar electric system, including heat!  The energy efficiency of the 4 inch SIP walls, roof, and floor allows for heating with less than 8 KWh per day in the middle of winter. The life cycle cost of this building, including building construction cost and electricity from solar, is about $50 per month, over the expected 25 year service life of the solar electric system.  You can not find rent that cheap.  The building should remain another 25 years or more.  [see below]

This 8 x 8 is built with 2 inch SIP wall panels fabricated with mahogany plywood,  ON SALE at $2,195.

Zero Energy Buildings

Olympic Energy Systems has an interest in these buildings, as they allow for the cost-effective development of Zero Energy Buildings.  We are putting three basic principles to work:

  • Optimized Space (minimal square footage)
  • Energy Efficient Materials (i.e., use of SIPs)
  • Solar Energy Systems (appropriately sized)

A typical specification for these SIP buildings includes:

BUILDING SIZE (8 x 12, 16 x 16, 16 x 24, etc.),
SIP PANEL WIDTH (2, 4, 6, 8, 10, or 12 inch nominal),
ROOF TYPE (Three Tab, Metal, Other),
DOORS & WINDOWS (Quantity, Size, and Location)

Frequently Asked Questions...

Q: Are building permits required?
A: Structure size, use intent, and your county or city codes are determining factors.  Plumbing and electrical DO require permits.  Buildings permits may be exempted due to size and intended use.

Q: Are SIP materials and buildings green?
A: They are environmentally friendly to produce, very energy efficient when in service, and can be recycled.  This material is also free of formaldehyde off-gassing.

Q: What is the R-Value (insulation value)?
A: 6 inch nominal floor and roof panels are R-23 and 4 inch nominal wall panels are R-16, both avoiding the thermal block present in standard framing.

Q: Do the structures require a foundation?
A: Most of the building kits come with a floor structure that attaches to pressure treated skids.  The skids can be attached to pier pads and leveled with post brackets.  If a concrete floor is desired, the insulated floor will be omitted from the kit and walls can be attached to the concrete floor.

Q: What site preparation is needed?
A: A level surface on to which to locate the building.  With the use of pier blocks, an inclined surface can be used.

Q: Can the placement of windows and doors be changed?
A: Window, Door, and Wall panels are all interchangeable to any position around the building and more can be added at additional cost.
