Standard Practice for Inspection and Maintenance of Commercial Building HVAC Systems

ASNI/ASHRAE/ACCA standard practice for the inspection and maintenance of commercial building heating, ventilation, and air conditioning (HVAC) systems. The document describes the minimum acceptable levels of maintenance in order to provide consistency and improve thermal comfort, energy efficiency, and indoor air quality.

 

Successful Measurement and Verification Strategies

Briefing document providing state ESPC program administrators—the individuals who oversee or provide ESPC technical support to their constituent state, local, healthcare, and/or educational facilities—with a selection of tested strategies to support successful M&V of ESPCs implemented in the state and local public sector.

 

NEMI Ventilation Verification Specification (for use in ongoing/annual assessments)

Ventilation Verification for Indoor Air Quality (IAQ) is a physical assessment of the existing Heating, Ventilation and Air Conditioning (HVAC) infrastructure. The Ventilation Verification Assessment establishes an HVAC system’s baseline for adequate ventilation. The specification allows school districts, building owners, and occupants to require Ventilation Verification within their buildings when not required by code.

Guideline 36-2021 -- High-Performance Sequences of Operation for HVAC Systems

ASHRAE Guideline 36, High-Performance Sequences of Operation for HVAC Systems, was created to develop and maintain best-in-class standardized HVAC control sequences. This guideline is all about the concept of “less is more.” Guideline 36 was created by ASHRAE’s Technical Committee 1.4, Control Theory and Application to maintain and publish best-of-class control sequences that meet or exceed the requirements of published ASHRAE standards such as 90.1, 62.1 and 55. These sequences are intended for use with fully programmable DDC BAS systems controlling variable speed/capacity equipment.
