The design team and project partners enlisted to reimagine the new Summit House, which is more than double the size of the former structure, were met with a unique set of opportunities and challenges: revitalizing the sky-high attraction while adhering to the highest green building standards.
Failure to properly insulate below-grade can be a costly misstep for the design-build sector. Materials like expanded polystyrene (EPS) rigid foam insulation are a cost-effective solution, affording proven moisture resistance, long-term thermal performance, and compressive strength.
A new study from the Alaska University Transportation Center, University of Alaska Fairbanks, recently reported on R-values measured on insulation removed from below-grade applications in harsh climates. This supplements data from two previous similar research projects. All the three studies reported the in-service R-values per inch of extruded polystyrene (XPS) and expanded polystyrene (EPS) insulation installed under roads and airport runways with the time in-service ranging from one to 31 years.
High-performing commercial buildings are becoming popular because of evolving codes and stricter standards for occupant safety, comfort, and energy efficiency. One can achieve high-performing building envelopes by combining various cavity insulation solutions, such as foam sheathing and insulation behind brick, stucco, concrete, and other cladding systems.
Today, the design-build sector is increasingly specifying tapered expanded polystyrene (EPS) insulation solutions to comply with codes—many existing buildings that are being retrofitted require the slope to be altered to meet regulations—as well as save time and money on the roof.
