Full mechanical design for new construction and existing buildings — residential, mixed-use, commercial, institutional, and healthcare. Abyssinia Consulting acts as Mechanical Engineer of Record from schematic design through permit, tender, construction administration, and close-out.

Whole-building energy simulation (IES-VE, HAP, eQUEST) supporting code compliance, funding applications, and incentive programs — from early design guidance to permit and occupancy documentation.

Building commissioning services that verify mechanical, electrical, and automation systems perform as designed — protecting owners through construction and into operation.

On-site whole-building and suite-level airtightness testing with calibrated fan equipment — quantifying envelope performance for code compliance and funding programs.

Mechanical engineering for healthcare and public-sector occupancies — designed to healthcare ventilation standards and delivered within operating facilities.

HVAC and plumbing upgrades for occupied buildings — improving performance and reducing emissions without disrupting operations.
