CLD Lighting Design Codes, Standards & Regulations

Question 1

ASHRAE 90.1 limits relate to:

Accepted Answer

Watts per area limits

Answer

ASHRAE Standard 90.1, "Energy Standard for Buildings Except Low-Rise Residential Buildings," sets minimum energy efficiency requirements for building design and construction. For lighting, it primarily establishes maximum allowable Lighting Power Densities (LPD), expressed as watts per square foot or square meter, for various space types. These limits aim to reduce overall energy consumption from lighting systems in commercial and institutional buildings.

Question 2

IECC governs:

Accepted Answer

Energy efficiency requirements

Answer

The International Energy Conservation Code (IECC) is a model code that establishes minimum energy efficiency requirements for new and renovated buildings. It provides comprehensive guidelines for building envelopes, mechanical systems, water heating, and, importantly, lighting systems. The IECC aims to promote energy conservation and reduce greenhouse gas emissions through efficient building design and construction practices.

Question 3

IES LM‑79 covers:

Accepted Answer

LED photometry

Answer

IES LM-79 is an Illuminating Engineering Society (IES) approved method for the electrical and photometric measurements of Solid-State Lighting (SSL) products, specifically LEDs. This standard outlines procedures for measuring total luminous flux, luminous intensity distribution, electrical power, efficacy, and chromaticity. It ensures consistent and accurate reporting of LED product performance data, which is crucial for designers and consumers.

Question 4

NFPA 101 requires minimum _____ along egress path.

Accepted Answer

1 fc

Answer

NFPA 101, the Life Safety Code, specifies minimum illumination levels required for means of egress (exit paths) to ensure safe evacuation during emergencies. It mandates a minimum average illumination of 1 footcandle (fc) at the floor level along the path of egress. This ensures sufficient visibility for occupants to safely exit a building, even during power outages when emergency lighting is active.

Question 5

UL listing indicates:

Accepted Answer

Safety compliance

Answer

UL (Underwriters Laboratories) is a global safety certification company that tests products and components for safety. A UL listing or certification indicates that a product has been tested and meets specific safety standards, reducing risks of fire, electric shock, and other hazards. It signifies that the product complies with recognized safety requirements, providing assurance to consumers and regulators.
