Cut hospital emissions without touching patient safety.
Calculators, an engineering toolkit and vetted sources for facility managers and MEP engineers who run buildings that never close.
Eight calculators · 42 worksheets · EPA eGRID2023 factors · formulas published on the methods page · no account needed except to save a LEED project
Estimate = (MWh × (1 − reduction) − solar) × grid factor. Location-based Scope 2 only. See methods. For Scope 1 and 2 together use the full carbon footprint calculator.

Calculators
One question at a time: carbon footprint, EUI, chilled water efficiency, life-cycle cost, solar, refrigerants, anesthetic gases. Nothing is stored.

Plan LEED v5 prerequisites, points and evidence for your facility. The only place a free account saves anything.
Start a LEED projectStart where hospitals actually lose energy
Measure before you cut
Sub-meter chillers, air handlers, medical gas plant and operating rooms so savings are provable.
Measurement playbookOptimize chilled water and air
Plant sequencing, VFDs, resets and scheduling, with pressure relationships kept intact.
HVAC playbookRemove high-impact gases
Anesthetic agents, nitrous oxide leaks and refrigerants are Scope 1 emissions many hospitals never count.
Gases playbookAdd clean supply
Solar, storage and resilience planned together with your critical power design.
