HVAC: Hospitals and health care facilities
1 AIA CES Learning Unit (LU) after passing a 10-question exam
Providing cooling/heating comfort and energy efficiency in hospitals and health care buildings is an ongoing challenge for mechanical engineers. Emphasis on building performance, indoor air quality (IAQ), and adoption of energy-efficient building codes is increasing. Designs are based on a host of variables beyond space type and understood loads including operating costs, first cost, life cycle cost, and measurement and verification (M&V) requirements.
Demand for historically typical HVAC technologies, such as variable-air-volume (VAV) and water-cooled chillers, is evolving to include a variety of systems. One case study will focus on chilled beams, and the second will focus on dual-path air handling units (AHUs).
- Explain the applicable codes and standards: ASHRAE Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings, California Title 24, ASHRAE Standard 189.1-2014, Standard for the Design of High-Performance Green Buildings, ASHRAE 170: Ventilation of Health Care Facilities, and International Energy Conservation Code (IECC).
- Acquire a basic understanding of the various heating and cooling technologies and systems, with an emphasis on air quality and efficiency.
- Analyze the pros and cons of heating and cooling technologies, specifically in hospitals.
- Compare HVAC systems via case studies of engineering projects.
