The Structural Insulated Panel Association (SIPA) announced the winners of the 2025 Building Excellence Awards at its annual meeting in San Juan, Puerto Rico, January 27th - 29th. Now in its 23rd year, the trade association’s offsite construction award program recognizes standout residential and commercial projects that illustrate the thermal performance, design flexibility and resiliency of structural insulated panels (SIPs). To meet increasingly tough building and energy codes in all climate zones, a growing number of industry professionals are choosing SIPs to deliver a nearly impermeable building envelope that prioritizes the comfort, health and safety of the homeowner or future building occupant.

“The adoption of forward-thinking building materials and construction methods is a critical component of the global transition plan to a lower-carbon future,” Jack Armstrong, Executive Director and COO for SIPA said. “That’s where turnkey building envelope systems like SIPs come into play—building with SIPs is the most efficient way to deliver a superior structure. This year’s Building Excellence Award winners are a true testament to the qualities that have become synonymous with SIPs, and to the commitment of the industry professionals who are ensuring a more sustainable future.

The Building Excellence Awards gives SIP builders, designers and manufacturers an opportunity to showcase exemplary residential and commercial projects completed the year prior. To be eligible for an award, SIPs must be used on at least 50 percent of the building envelope, determined by square footage of the exterior walls and roof. This year, the Building Excellence Award judges evaluated each project for its creative use of SIP construction, its overall design and structural engineering innovation, and its commitment to environmental sustainability.

In addition to the building categories listed below, entries that demonstrated eco-efficiency, health, resilience and renewable energy were considered in the high-performance (HP) running for that category.
