SIPLOCK Steel & Zero-Energy Design

 

SIPLOCK. 21st Century Future Proof Design

Monolithic & Structural Steel I-Beam Construction

 

Monolithic Steel Construction & Zero-Energy Design.

 

Structural Steel provides unmatched strength, durability and integrity for single and multi-story structures. Roof, wall, steel columns and concrete footings are designed to be a single monolithic structure.

 

The monolithic steel design makes it nearly impossible for hurricane force winds to uplift its roof assembly.  Hurricane winds would need to uplift the entire structure for serious damage to occur. Highly unlikely!

Add the best available energy technology and resources.                                                               

Heat Pump, Geothermal, Co-Generation, Solar, Wind, PV and ERV technologies.

 

SIPLOCK is indistinguishable from conventional structures.

Perfectly square, level, flat and true. All loads go to steel columns.

Walls and roofs accept any siding, roofing and trim materials.

 

 

 

 

 

SIPLOCK Is simply Better

 

26 Gauge Galvalume Steel SIP

 

Hurricane, Tornado, Earthquake, Fire, Flood, Termite, Vermin, & Mold Resistant.

All-in One Wall & Roof assembly.

SIP wall and roof panel insulation is continuous from footers, eaves and roof ridge.

SIPLOCK is a structurally sound, load-bearing SIP with EPS thermal insulation.

SIPLOCK is clad, both sides with 26 gauge steel & Galvalume corrosion protection.

 

Three key design considerations for a passive house.

 

  1. Super high R insulation. (Whole wall R-value)(Critical Requirement)
  2. Minimize Thermal Bridging
  3. Airtight Envelope

Thermal Bridging in a wall assembly.

 

Oak Ridge National Labs has stated that the individual R-Value of each product, they evaluated, had very little to do with the R-value of a complete wall assembly.

Other studies indicate, more than 30% of a buildings heat loss or gain is from conductive thermal bridging.

In tests, a wood wall assembly had significant thermal bridging and air leaks from studs, corners, windows and doors. A wooden roof assembly could expect worse results because of rafter studs, roof and soffit vents.

R-Value is a measure of resistance to heat loss by conduction, convection, and radiation of various building materials.

 

 

Flir, a company that makes thermal imaging cameras, has some great shots of thermal bridging in action on their website. Here’s just one example showing the cold 2×4’s in a wall:

A schematic representation of what thermal bridging looks like in a typical residential house. The yellow at the studs, and the rim joist locations is not a pretty color for a building scientist, or a homeowner. Even worse, the low quality windows outlined in red represent even more heat loss, low interior surface temperatures and an increased potential for forming interior condensation.

 

Thermal bridging can be responsible for 30% of heat loss and heat gain.

Wood frame studs have a lower insulating value than the batten insulation between them, and if the studs are directly in contact with the inside and outside of a wall, they can act to conduct heat in and out, resulting in added high-energy costs.

Richard T. Bynum writes in Insulation Handbook:

 

In a typical wood stud wall, the wooden studs are thermal bridges, and will create a cold area (compared with the insulated cavity) where the stud meets the interior sheetrock. This is illustrated in the infrared image above where the cold spots created by the studs show up as dark lines. These cold spots compromise the insulation and lower the effective average R-value of the whole wall. In addition to lowering the total R-value of a wall, the cold spot can lead to condensation problems. If any moisture did manage to get into the wall cavity, the cold wood stud near the sheetrock would be the first surface where water vapor would condense into liquid form.

Currently, most wall R-value calculations are based on experience with conventional wood frame construction, and they do not factor in all the effects of additional structural members at windows, doors and exterior wall corners. Thus they tend to overestimate the actual field thermal performance of the whole wall systems.

 

Since the R-value of the insulation material alone does not accurately indicate the average R-value of the whole wall system, Bynum describes three methods for measuring R-values:

 

According to the 2006 IECC, the design effectiveness of all high-energy efficient construction directly affects the HERS rating.

 

Clear wall R-value: This is the R-value of a wall with just studs and does not include the framing included in windows, doors and exterior corners.

 

Center of Cavity R-value: This is the R-value estimate of the area of the cavity space between studs that contains the most insulation.

 

Whole wall R-value: This is an R-value estimation that includes both the clear wall estimate of R-value and takes into account additional framing like windows, doors and exterior corners.

 

Bynum makes the statement that for some conventional wall systems, the whole wall R-value is as much as 40 percent less then the clear wall R-value.

ASHRAE tests indicated: A six-inch stud wall, 24 inch on center with R-19 fiberglass batts tested out with an R-Value of 13.7. Nearly 33% less as a completed wall assembly than the fiberglass insulation.

The high R-Value of an insulation material, in a wall or roof assembly, does not equal the total thermal efficiency rating.

Note: We excluded the following negative factors affecting the total wall R-value.

They include

  1. Thermal Bridging of firing for wallboard
  2. Air Leakage at corners, lintels and plates.

 

CBS wall construction has very little R-value compared to other construction methods.

SIPLOCK Air-Tight design.

 

Oak Ridge National Labs stated that 40% of heat loss or gain is due to air leakage!

Conventional construction methods suffer considerable heat gain and loss through cracks, poorly weatherized windows, doors, roof ridge, soffit and crawl area vents. Conventional construction methods promote air leakage from electric wall outlets, kitchen, bath and clothes dryer venting.

Conventional construction methods waste energy, promote mold and spore growth by the installation of HVAC ducts within non-conditioned vented attics, crawl spaces and basements.

 

SIPLOCK design eliminates energy-wasting air leakage and air quality problems.

SIPLOCK eliminates air-leakage, which contribute, to high temperatures, humidity, condensation, rot, mold and spore growth from leaky attics, crawl spaces, rim joists and sill plates.

SIPLOCK eliminates heat gain or loss from air infiltration.

SIPLOCK airtight closed envelope design eliminates the number one cause of uncomfortable interior humidity, drafts and condensation from roof ridge, soffit and crawl area vents.

 

Energy Savings.

 

In an independent energy survey, according to the Structural Insulated Panel Association (SIPA), an 180,000 SF senior living facility in Florida is saving thousands of dollars each month. HVAC costs have been verified at $0.025 (2 ½ cents) per SF.  

A 28,000 SF residence has recorded HVAC costs of $0.018 (1.8 cents) SF.

 

A passive house could expect to use about 1.36KWh per square foot of HVAC conditioned space per year.

In Florida, for example a Siplock Energy Star rated 2700 sq. ft. home could consume about .42 Kw per hour for HVAC you could expect about a $25 monthly cost for HVAC. 2011 Florida Electric average rate is 12 cents per KWh.

 

A similar home in NY would be about $65 monthly for heating and cooling.
