  Energy Efficiency and Long-Term Savings With accel-E™ Wall Systems

The Board of Directors for the Human Resources Development Commission of Allegany County, Maryland decided a new headquarters was the most cost effective solution for its needs. In particular, the organization needed its new headquarters to decrease its occupancy costs – something they could achieve by erecting a LEED®-approved facility that was both cost-effective and environmentally friendly.

That made the accel-E™ Steel Thermal Efficient Panel (S.T.E.P.) wall system an attractive choice for architect Gary Moshier.

“I have always liked products that give you a better quality building envelope, and this seemed like a good way to go,” said Moshier, a partner in Moshier Studio, which designed the facility.

The accel-E™ S.T.E.P. system overcomes many common causes of poor energy efficiency by fusing specially designed steel studs and expandable polystyrene (EPS) insulation together into a single continuous panel system. This eliminates air gaps and irregularities that can diminish the performance of conventional framing and insulation.

Slots in the framing members allow insulation to mold through the steel, which further reduces thermal bridging and heat transference, blocks air intrusion, and adds thermal resistance. As a result, the accel-E™ panels offer tested insulating values that far surpass traditional framing, sheathing and batt wall assemblies.

The S.T.E.P. system’s steel framing members are recycled steel, and are themselves recyclable. In addition, the EPS insulation does not shrink, settle, emit harmful gases, or contribute to diminished air quality. As a result the S.T.E.P. wall system contributes points to as many as four LEED® categories – a fact that influenced the HRDC board’s decision, according to Moshier.

“I think it was a combination of the energy performance, plus fewer joints for a more controlled joining system than other alternatives,” he said. “Plus the fact that these panels contributed to LEED points in the Energy Efficiency Category was a positive.”

The accel-E™ panels are available in 5 and 8 inches, and can be produced in virtually any height, limited only by the mode of transportation. The materials used in the panels resist mold and mildew. Developed and marketed by SYNTHEON Inc. (Accelerated Building Technologies, LLC), the accel-E™ system fully complies with both the 2006 International Building Code (IBC) and the 2006 International Residential Code (IRC).
