Symposium Summary

Under the Energy Policy Act of 1992, the US Department of Energy (DOE) is required to regularly review each new edition of ASHRAE Standard 90.1 and make a determination as to its advancement in minimum building energy efficiency. Upon such determination, each State must then review their state energy code to ensure that it delivers building energy efficiency at least as good as the latest version of 90.1.

In 2021 DOE issued its determination that the 2019 version of the Standard offers greater energy savings over the 2016 Standard. State energy code reviews are now underway.

Varitec seeks to stay well informed about this ever-changing energy code landscape so we can support our customers with regular education programs along with our building and HVAC design support, a diverse array of equipment and mechanical systems offerings, and other services.

To further advance our committed education initiative, Varitec is conducting our first Sustainability Symposium. This event is intended to address many of the recent and upcoming changes to the building energy code landscape and to specifically address some of the unique Sustainability challenges we face in our built environment here in the desert Southwest.

Mr. Chris Mathis, Principal of Mathis Consulting, ASHRAE Fellow and Distinguished Lecturer and member of the 90.1 Development Committee at ASHRAE will present Why Buildings Matter an AIA accredited program addressing the diverse societal connections to building energy performance, as well as many of the current and upcoming 90.1 requirements. The Symposium will also include a presentation by ASU’s own AVP of FDM, and University Architect, Dr. Ed Soltero, titled “Fine Tuning Your Building to a Region’s Exigencies” addressing ASU’s experience of sustainable buildings installed in the desert Southwest. .

Between presentations, round-table discussions will be held between attending participants and speakers to gather facts on what local challenges are impeding the design of efficient buildings and HVAC systems. Building design and construction specialists will learn from our speakers why sustainable designs are necessary, and what practical field experience and lessons learned our market should be aware of to advance the cause of more efficient and sustainable built environments.

The Symposium will conclude with Chris Mathis presenting on The Challenge of Sustainability, blending the feedback from the roundtables into a provocative view forward for everyone engaged in building design and performance.

This Symposium is intended for everyone engaged in buildings and building performance, including engineers, architects, urban planners, building officials, building managers, policy makers, students, developers, contractors and more.
