The Industry Hotspot: Hospital Building Energy and Anesthetic Gases

Energy and anesthetic gases dominate operations

Healthcare facilities have high emission intensity from energy-intensive operations and specialized medical emissions. Hospitals consume substantially more energy per square meter than typical commercial buildings due to continuous operation, HVAC requirements for infection control and operating room air quality, medical imaging equipment (MRI, CT scanners), and sterilization systems. Surgical anesthetic gases including desflurane and sevoflurane have very high global warming potential. Nitrous oxide used for anesthesia and analgesia also has significant warming impact. Medical waste including infectious materials requires incineration generating combustion emissions. Purchased medical supplies and pharmaceuticals create substantial Scope 3 footprint from manufacturing. NetNada tracks facility energy by department and use type, monitors anesthetic gas consumption by operating room and procedure, calculates medical waste disposal emissions by method, and aggregates purchased supply carbon footprints.

Health Care Delivery FAQs

Common questions about carbon accounting for this industry

Why are hospitals so energy-intensive compared to other commercial buildings?
Hospitals consume substantially more energy per square meter than typical office buildings due to operational requirements: Continuous operation: Hospitals operate year-round with minimal downtime unlike offices with evening and weekend closures. HVAC intensity: Infection control requires specific air change rates, temperature, and humidity. Operating rooms demand high air changes with HEPA filtration. Negative pressure isolation rooms for infectious patients. Medical equipment: MRI machines, CT scanners, imaging systems, and laboratory equipment run continuously. Sterilization: Autoclaves use steam for surgical instrument sterilization. Hot water: Patient care, cleaning, and sterilization require substantial hot water. Typical: Hospitals may consume two to three times energy per square meter versus office buildings. Track energy intensity trends and benchmark against peer hospitals by bed count and services offered.
How significant are anesthetic gas emissions and can they be reduced?
Anesthetic gases have very high global warming potential creating meaningful emissions despite small mass consumption. Desflurane has highest warming impact. Sevoflurane and isoflurane moderate impact. Nitrous oxide significant warming potential. Emission reduction strategies maintaining patient safety include: Low-flow anesthesia: Reducing fresh gas flow rates from conventional to optimized levels substantially decreases agent consumption while maintaining adequate anesthesia. Clinical studies confirm safety. Agent selection: Using sevoflurane instead of desflurane, or total intravenous anesthesia with propofol for suitable cases. Regional anesthesia: Nerve blocks and spinal anesthesia for appropriate procedures avoiding general anesthesia entirely. Waste gas capture: Experimental systems capturing exhaled anesthetic for destruction or reprocessing. Engage anesthesiology departments through education and protocol development. Track anesthetic emissions per surgical case as performance metric.
Should hospitals report Scope 3 emissions from purchased medical supplies?
Yes, Scope 3 Category 1 (Purchased Goods and Services) typically represents substantial portion of hospital carbon footprint often exceeding operational Scope 1 and 2. Purchased supplies include: Medical devices and instruments: Single-use devices, surgical instruments, implants with manufacturing emissions.
