ASHE Sustainability & Energy Efficiency 2

Question 1

Which ASHRAE standard provides the primary energy efficiency requirements for healthcare facility HVAC system design?

Accepted Answer

ASHRAE 90.1

Answer

ASHRAE 90.1 sets the energy efficiency baseline for building systems including HVAC in healthcare facilities.

Question 2

A hospital is evaluating demand-controlled ventilation (DCV). In which healthcare space is DCV typically NOT recommended?

Accepted Answer

Patient rooms requiring negative pressure

Answer

Infection control rooms requiring negative pressure isolation must maintain constant airflow and cannot reduce ventilation based on occupancy.

Question 3

What is the primary purpose of a building commissioning process in a healthcare facility?

Accepted Answer

To verify that systems are installed and operating as designed

Answer

Commissioning verifies that all building systems are installed, calibrated, and operating according to design intent and owner's project requirements.

Question 4

Which metric best measures the overall energy efficiency of a hospital's central chilled water plant?

Accepted Answer

Kilowatts per ton (kW/ton)

Answer

kW/ton measures the electricity consumed per unit of cooling delivered by the entire plant, capturing efficiency of chillers, pumps, and cooling towers together.

Question 5

A healthcare facility installs a cogeneration (CHP) system. What is a key operational advantage for energy resilience?

Accepted Answer

Provides simultaneous on-site generation of electricity and usable heat

Answer

CHP systems capture waste heat from electricity generation for space heating or domestic hot water, significantly improving overall fuel efficiency.
