In our presentation we will discuss basics of BACnet, some of the types of BACnet and how these were used to create BACnet/SC, a secure type of BACnet. We will discuss BACnet/SC, its features, network requirements and security requirements. We will also discuss public key encryption which is how BACnet/SC provides its security.

ASHRAE Guideline 36 “High Performance Sequences of Operation for HVAC Systems” was published in 2018 and updated in 2021. It provides standardized sequences of operation for common HVAC equipment found in commercial buildings, including central plant, air handling units, and terminal units. It aims to deliver direct benefits that include reduced design effort, reduced programming and testing...

10. NREL’s Zero Energy Analytics and Dashboard

Stephen Frank (National Renewable Energy Laboratory)

The National Renewable Energy Laboratory’s (NREL's) Research Support Facility (RSF), constructed in 2011, was designed as a zero energy building and achieved LEED Zero Energy certification in 2020. Recently, NREL developed a new dashboard for monitoring the RSF’s ability to maintain zero energy operation through major building changes related to COVID and remodeling. The dashboard engages...
