What we design

Heating, cooling, ventilation, and controls — one coordinated mechanical design for Oshkosh healthcare. Engides delivers load calcs, equipment schedules, duct layouts, and ASHRAE 90.1 documentation that the Oshkosh building department reviewers approve, backed by Apex Grid Engineering's licensed engineers.

  • Controls sequences written for the Oshkosh operator, not just the submittal: economizer changeover, morning warm-up, and unoccupied setback logic that actually gets programmed.
  • Energy modeling and Title-24-style documentation for Oshkosh healthcare: our compliance forms match the drawings, so the Oshkosh building department energy review doesn't generate a second correction cycle.
  • the Oshkosh building department mechanical review in Oshkosh, WI zeroes in on load calcs, ventilation rates, and equipment schedules — our Oshkosh submittals carry all three with matching numbers across every sheet.
  • Oshkosh higher education need equipment that handles severe winters and lake effect without short-cycling: we select and stage systems for part-load efficiency, not just design-day capacity.
  • Heating and cooling load calculations for Oshkosh healthcare using severe winters and lake effect design conditions — envelope, occupancy, and ventilation loads modeled so equipment is sized right, not oversized by habit.
