Format changes to improve usability and readability: Lighting Modified requirements for exterior and interior lighting power densities to reflect new lighting levels in the IES Lighting Handbook.

Within asbrae sections of the standard, there are some variations to this. There are many controls that hot water systems need and each control has a different requirement.

Changes to Building Envelope include skylights, solar reflectance, thermal emittance, air barriers, and solar orientation. This edition of the standard has several new features and includes changes resulting from the continuous maintenance proposals from the public, including all of the Addenda to Standard Copy, paste, print, and annotate content with one click, and see interpretations, addenda, and errata in the context where they matter.

There are systems that can not be used and things that systems must have to meet the requirements. This is because there are many types of HVAC systems each with different requirements. Ansk rule changes were made to heat pump auxiliary heat, economizer shutoff, lighting controls, humidification systems, cooling towers, and the simulation of preheat coils.


The provisions of this standard apply to the envelopes of buildings, provided that the enclosed spaces are 1 heated by a heating system whose output capacity is greater than or equal to 3. Requirement that air-cooled DX cooling units with economizers have a monitoring system to determine that the air economizer is working properly. Views Read Edit View history. A building performance simulation is then performed on the proposed building design.

ANSI/ASHRAE/IES Standard 90.1-2016

Superseded Editions of Each one has different requirements to meet. The performance approach is also used to demonstrate design energy efficiency, often expressed as percent better than ASHRAE Standard The provisions of this standard do not apply to a single-family houses, multi-family structures of three stories or fewer above grade, manufactured houses mobile homes and manufactured houses modularb buildings that do not use either electricity or fossil fuel, or c equipment and portions of building stanvard that use energy primarily to provide for industrial, manufacturing, or commercial processes.

A few states do not apply any energy conservation standards for their government and commercial buildings. Significant technical content changes: A new Reference Standard Reproduction Tsandard 1 is provided at the end of the document. DOE issued a positive determination and notified states standwrd they should adopt Heating, ventilating, and air conditioning American engineering organizations.


The ECB is expressed in units of dollars. General and specialty contractors who must construct buildings in compliance with the Standard. Current status of adoption into energy codes is tracked by the Building Codes Assistance Project.

Streamlines the process of showing compliance. There are also requirements for pool heaters, pool covers, and heat traps for heated pools. Most states apply the standard or equivalent standards for all commercial buildings.

Each change analysis features the affected code and Standard sections and identifies the change as added text, a modification of the existing language, or deleted text. The standard you purchase will include the most up-to-date additions. There are also interior lighting controls that need to be installed for buildings larger than sqft.

Lighting also has many requirements asjrae follow, which includes the prescriptive requirements to determine the quantity of lights for the building.
