ASHRAE Guideline 36

ASHRAE Guideline 36 provides best-in-class standardized, uniform sequences of operation that are intended to maximize energy efficiency and performance, provide control stability, and allow for real-time fault detection and diagnostics in a building's HVAC system. These control sequences provide various benefits: from reduced engineering, programming and commissioning time to energy consumption as well as improved indoor air quality and communication between specifiers, contractors, and operators. By starting with a better set of control sequences, it is possible to create a better specification which ultimately results in a better building.

Enhanced Desigo DXR VAV application supports ASHRAE Guideline 36

With the newest update to the VAV application, Desigo DXR Room Automation Controllers now provide owners, contractors and commissioning agents with the following features and benefits…

  • System Requests — Improve energy efficiency by optimizing the HVAC demands between the central system and multiple zones
  • Demand Control Ventilation — Provides good indoor air quality while delivering substantial energy and cost savings, especially for facilities with variable & unpredictable occupancy
  • Dual Maximum Reheat Sequence — Improves energy efficiency and occupant comfort
  • Time Averaged Ventilation — Saves energy by optimizing minimum airflow rates
  • Fault Detection and Diagnostics — Identifies inefficiencies with installed hardware (HVAC equipment and building automation devices [i.e. sensors, actuators, and dampers]) to proactively reduce energy usage and eliminate waste

 

Understanding the guideline and applying it to real projects

To help improve understanding of:

  • the history and future of ASHRAE Guideline 36
  • when and how ASHRAE Guideline 36 needs to be utilized in projects
  • the controls requirements of a project between different phases of design and construction
  • the best ways to apply Guideline 36 when creating a building specification for renovation and new construction projects
