The ASHRAE 90.1 standard relates to energy efficiency for:

Building-related provisions that aim to design new federal buildings so they achieve at least a 30 percent improvement over the ASHRAE 90.1 standards in terms of energy efficiency.

ASHRAA 90.1 is an important piece of legislation as it helps organizations reduce their carbon footprint and lower operational costs by encouraging responsible use of resources such as water, electricity, gas, and other sources used within buildings to meet minimum building performance requirements.

The standard covers various aspects including:

- Minimum levels for lighting power density

- Building envelope properties

- HVAC systems design

ASHRAA 90.1 also addresses commissioning procedures which ensure all new mechanical & plumbing (MEP) systems are properly tested and verified before being put into operation to guarantee they function as intended.

In summary, ASHRAE 90.1 is a crucial piece of legislation that has far-reaching implications for the construction industry by promoting energy efficiency through its various provisions relating mainly to federal buildings while also contributing towards sustainability goals at both national and international levels alike!
