It is frequently used as a baseline for comparison during energy retrofit projects or any project that employs building performance simulation. Plan examiners and field inspectors who must enforce the Standard in areas where it is adopted as code. Purchase Looking for the SI Edition? 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.
There are also many requirements on lighting that include exit signs and exterior lights. Others apply the standard or equivalent standards for all government buildings. Economizer requirements were added for more climate zones and smaller systems.
Retrieved from “Archived copy” PDF. This edition, which supersedes Standard Improved clarity on defining exterior walls, building ieana, fault assumptions for the effective R-value of air spaces, and calculation procedures for insulating metal building walls.
Significant technical content changes: Many lighting control requirements were added, including independent functional testing of lighting controls, occupancy and vacancy controls, exterior lighting controls, and whole-building shutoff.
ASHRAE – Wikipedia
Purchasers who select the redline upgrade receive both the current standard and the redline in print or digital format. The performance approach is also used to demonstrate design energy efficiency, often expressed as percent better than ASHRAE Standard The version of the standard provided in this preview includes all addenda that were approved by the Board of Directors as of January 1, Home Technical Resources Bookstore.
New buildings being constructed and the systems that run the new buildings would be covered by the standard. The HVAC system has many different requirements that have to be met.
Modeling rule changes were made to heat pump auxiliary heat, economizer shutoff, lighting controls, humidification systems, cooling towers, and the simulation of preheat coils.
Archived copy as title.
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 Ans provisions also apply to the following systems and equipment used in conjunction with buildings: Changes to Building Envelope include skylights, solar reflectance, thermal emittance, air barriers, and solar orientation.
Most states apply the standard or equivalent standards for all commercial buildings.
In the ASHRAE Board of Directors voted to place the standard on continuous maintenance, based on rapid changes in energy technology and energy prices.
Anssi stringency requirements for metal building roofs and walls, fenestration, and opaque doors. The climate zones have been reduced from 26 to 8 and the Lighting LPDs have been reduced as well.
Read-Only Versions of ASHRAE Standards
This baseline ECB is established using building performance simulation to model a building with the same size and program as the project building, built according to the prescriptive requirements of ASHRAE Lighting Modified requirements for exterior and interior lighting power densities to reflect new lighting levels in the IES Lighting Handbook. Looking for previous revisions? Dedicated outdoor air systems now include both efficiency and rating requirements for compliance.
Intended to be useful to numerous types of building professionals, including: Within the sections of the standard, there are some variations to this. The HVAC section has the most requirements because there are so many different types of systems.
