Study Notes

Energy Conserving Design of Buildings

  • The main purpose of the guidelines is to conserve energy in building design.

Air Terminology

  • Exhaust air refers to air that is removed from a building.
  • Return air is the air that is circulated back to the heating or cooling unit.
  • Indoor air is the air inside a building, which may be a mixture of outdoor air and recirculated air.
  • Outdoor air is the air outside a building that is used for ventilation.
  • Ambient air is the surrounding air, which includes indoor and outdoor air.

Heating, Ventilation, and Air Conditioning (HVAC)

  • Air treatment is the process of controlling air temperature, humidity, cleanliness, and distribution.

Organizations and Certifications

  • ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) focuses on building systems, energy efficiency, indoor air quality, refrigeration, and sustainability.
  • A Certified Energy Manager (CEM) is responsible for managing and conserving energy in buildings.

Energy Efficiency

  • BEP stands for Brake Horsepower, referring to a pump's operation.
  • The ratio of heating or cooling provided to electrical energy consumed is represented by COP (Coefficient of Performance).
  • BTU (British Thermal Unit) is a unit of heat energy.
  • CECO stands for California Energy Commission, related to energy management.

Building and Definitions

  • A building is a structure with walls and a roof, designed for various purposes.
  • ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) is a professional organization focusing on building systems and energy efficiency.

Explore the purpose and guidelines outlined in the 2020 edition for encouraging energy conserving design of buildings, with a focus on reducing energy use while considering cost effectiveness, building function, occupant comfort, health, safety, and productivity. Learn about the minimum requirements for new buildings and major renovation of existing buildings.
