Each one has different requirements to meet. Digital Collections —Need company-wide access?

Retrieved from “Archived copy” PDF. This is because there are many types of HVAC systems each with different requirements.

This standard provides a minimum energy-efficient requirements for the design and construction of 1 new buildings and their systems, 2 new portions of buildings and their systems, and 3 new systems and equipment in existing buildings and b criteria for determining compliance with these requirements. The provisions anai 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.

Each section of the building envelope, Roof, Walls, and Floor have different requirements for each of the mandatory provisions.

Standard 90.1-2016 — Energy Standard for Buildings Except Low-Rise Residential Buildings

There are systems that can not be used and things that systems must have to meet the requirements. There are also requirements for pool heaters, pool covers, and heat traps for heated pools.

Some sections have mandatory provisions, simplified approaches, or trade-off opportunities. Purchase Looking for SI Edition? The standard would also apply to additions to existing buildings and their systems as well as alterations to an existing buildings system.

The version of the standard provided in this preview includes all addenda that were approved by the Board of Directors as of January 1, New buildings being constructed and the systems that run the new buildings would be covered by the standard.

The Performance Rating method used for calculating building energy performance ratings for certain building rating systems and incentive programs.


The building envelope has to be categorized into 3 different categories of conditioned space which are a nonresidential conditioned space, b residential conditioned space, and c semiheated space. This standard provides the minimum requirements for energy-efficient design of most buildings, except low-rise residential buildings. DOE issued a positive determination and notified states that they should adopt It does not include any addenda, interpretations, or errata approved after this date.

Gain access to the most critical updates, the real-world application of those changes, and why they originated. It offers, in detail, the minimum energy efficiency requirements for design and construction of new buildings and their systems, new portions of buildings and their systems, and new systems and equipment in existing buildings, as well as criteria for determining compliance with these requirements.

ASHRAE – Wikipedia

Lighting Modified requirements for exterior and interior lighting power densities to reflect new lighting levels in the IES Lighting Handbook. There are some states that use other energy conservation standards for all commercial buildings and some other states that use a combination of the ASHRAE The scope was expanded to include defined industrial processes, which in the edition includes only economizers for data centers.

Changes to Building Envelope include skylights, solar reflectance, thermal emittance, air barriers, and solar orientation.

This edition, which supersedes Standard 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 A new Reference Standard Reproduction Annex 1 is provided at the end of the document. Intended to be useful to numerous types of building professionals, including: Product manufacturers, state and local energy offices, policy groups, utilities and others.

Increased stringency requirements for metal building roofs and walls, fenestration, and opaque doors. One-column format for easier reading Exceptions separated, indented, and set apart with a smaller font size Italicized defined terms Changes to table formats to provide contrast between rows Dynamic PDF navigation Structural changes: Subscriptions are also available for a local network to provide affordable access for your entire office.

It offers, in detail, the minimum energy-efficient requirements for design and construction of new buildings and their systems, new portions of buildings and their systems, and new systems and equipment in existing buildings, as well as criteria for determining compliance with these requirements.


The pipes that hold the hot water need to be insulated and there are certain insulation requirements for each system type and piping material. The provisions also apply to the following systems and equipment used in conjunction with buildings: Daylighting and associated lighting control requirements were added.

A building performance simulation is then performed on the proposed building design. The HVAC section has the most requirements because there are so many different types of systems. Modified requirements for lighting control to add additional controls in some space types and options to others to allow easier application of advanced controls. Each system must meet the manufactures sizing guidelines. It is an indispensable reference for engineers and other professionals involved in design of buildings and building systems.

Minimum efficiency requirements for many types of HVAC equipment were revised.


Many lighting control requirements were added, including independent functional testing of lighting controls, occupancy and vacancy controls, exterior lighting controls, and whole-building shutoff. This edition comprises numerous energy-saving measures and incorporates changes from more than addenda.

Restrictions were placed on overhead air heating. Building Envelope Envelope verification in support of reduced air infiltration and increased requirements for air leakage of overhead coiling doors. 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.

A draft of the standard was issued on June 21,to 5, industry stakeholders for public review. This allows it to be updated multiple times in a year.
