By hitching their wagon to the horse of Standard 90.1, LEED-related hard costs are rising and becoming increasingly misaligned with low-margin project cost models based largely on minimum energy standards within the project’s regulatory context.

Baselines and benchmarks are both valuable. A project's performance narrative should use both deliberately. The baseline grounds the conversation in the specifics of the project. The benchmark situates the project in the larger context.

Precis Engineering + Architecture capped a year of growth by creating two new C-suite roles.

Both ASHRAE 90.1-2022 and the 2024 IECC are published and available for adoption. Adoption will vary by region, but the direction is clear: expectations for tighter, more resilient building envelopes continue to rise as more municipalities move toward these standards into 2026.

St. Louis-based Case Engineering, Inc. celebrates its 30^th anniversary, a new President/CEO, and the retirement of Founder/CEO Darrell Case, PE, LEED AP.

Recent studies have shown that CI alone may not be enough for a building to achieve its designed level of energy efficiency. It’s time to look beyond CI alone and consider a holistic approach to façade design.

Under the LEED v5 BD+C prerequisite EAp3 Fundamental Commissioning, there are five specific requirements regarding building envelop commissioning.

While Weather-Resistive Barriers (WRBs), flashings, and sealants perform reliably in controlled conditions, the true challenge arises at joints, corners, and penetrations—where distinct components and trades meet.

Precis Engineering + Architecture, an award-winning design firm with offices in Ambler, Pa., and Cary, N.C., has promoted Jeff Crozier, PE, LEED AP BD+C, CEM, to Project Executive

A closer look at infiltration in building enclosure performance. Infiltration can have a major impact on building energy use and indoor air quality (IAQ) by allowing unconditioned and unfiltered air to penetrate a thermal enclosure.
