What Glumac does

Glumac is a US-based engineering consulting firm that delivers mechanical, electrical, and plumbing (MEP) design, sustainability consulting, building commissioning, building performance and energy modeling, architectural lighting, and technology integration services to owners of large building and infrastructure projects. The firm is organized around six integrated practice areas (MEP Engineering, Sustainability Consulting, Commissioning, Building Performance, Lighting Studio, Technology Integration) and serves clients across six market verticals: Commercial, Advanced Technology, Education, Government, Healthcare, and Science & Technology. Project scope spans landmark buildings such as the Wilshire Grand Tower, Levi's and SoFi Stadiums, the SFO terminal complex, the UC and CSU higher-education systems, and Kaiser Permanente hospitals.

The technical stack rests on Autodesk BIM360 cloud-based 3D building information modeling, energy modeling (central plant, daylight, envelope, water, distributed energy resources), and specialty commissioning including retro-commissioning and monitoring-based commissioning. The firm holds deep credentials in LEED, WELL, and Living Building Challenge delivery and participates in the AIA 2030 Commitment, the Carbon Leadership Forum's MEP 2040 Challenge, and ASHRAE 241 working groups. Notable technical outcomes reported in source data include building-level PUEs as low as 1.10, 70% energy cost savings on a historic HQ renovation, 100% solar operation at a California state office building, and approximately 34% of LEED baseline energy use at a mass timber commercial development.

Glumac generates revenue through project-based professional services fees billed against custom scopes for engineering design, sustainability consulting, and multi-year commissioning contracts. The go-to-market is direct enterprise field sales, pursued through competitive bids, RFQs, and direct procurement with government agencies (notably the City of Los Angeles, State of California, and SFO), universities (UC system, CSU system, University of Oregon), and large healthcare, technology, and commercial owners (Kaiser Permanente, Amazon, Oracle, Nike). Marketing is centered on a long-running 'Sustainability Matters' thought-leadership blog, webinars, and USGBC/ILFI/WELL conference partnerships. The firm operates from ten offices across California, Oregon, Washington, Nevada, and Texas; since the early 2020s it has operated as a subsidiary within Tetra Tech's High Performance Buildings Group while retaining the Glumac brand.
