The standard has been completely reformatted for ease of use and clarity. This standard provides the minimum requirements for energy-efficient design of most buildings, except low-rise residential buildings. Detailed illustrations and examples accompany each change.

This standard provides a minimum energy-efficient requirements for the design and construction of 1. Requirements were added for service water booster pumps and elevators.

There are many controls that hot ashraw systems need and each control has a different requirement. Modified requirements for lighting control to add additional controls in some space types and options to others to allow easier application of advanced controls. A draft of the standard was issued on June 21,to 5, industry stakeholders for public review.

This ieana because there are many types of HVAC systems each with different requirements.

The purpose of this standard is to provide minimum requirements for the energy-efficient design of buildings except low-rise residential buildings. General and specialty contractors who must construct buildings in compliance with the Standard. Other revisions affect the maximum fan power limits, pump head calculation, chilled water pipe sizing, radiant panel insulation, single-zone VAV, anwi supply air temperature reset.

The standard you purchase will include the most up-to-date additions. Lighting power densities LPD dropped slightly on average. DOE issued a positive determination and notified states that they should adopt Snsi technical content changes: 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with the same size and program as the project building, built according to the prescriptive requirements of ASHRAE Superseded Editions of Building Envelope Envelope verification in support of reduced air infiltration and increased requirements for air leakage of overhead coiling doors.

There have been multiple editions to it since. There are also many requirements on lighting that include exit signs and exterior lights. Energy recovery is required for many more HVAC systems.

Instructs the user in the application of: It is frequently used as a baseline for comparison during energy retrofit projects or any project that employs building performance simulation. Intended to be useful to numerous types of building professionals, including: Purchase Looking for the SI Edition? The proposed energy cost budget must be less than or equal to the baseline energy cost budget to achieve compliance.

Mechanical Large, electrically driven chilled-water plants are now required to be monitored for electric energy use and efficiency.
