CRC2018 Tech Sessions

TECH SESSION 1A — 8:30 AM to 9:30 AM
Chris Mathis – Energy Efficient Windows and Fenestration

There are now thousands of new, different window and glazing technologies available to both residential and commercial building professionals. Many of these technologies have dramatic impacts on HVAC sizing, peak loads and thermal comfort. This presentation will provide attendees with valuable information concerning key performance indices necessary in making energy efficient fenestration product decisions. Implications on HVAC sizing, peak loads and human comfort will be addressed. Implications for existing and new buildings will be discussed.

TECH SESSION 1B — 8:30 AM to 9:30 AM
Hoy Bohanon – Applying ASHRAE Standards to Existing Buildings

Many ASHRAE Standards are design standards addressing the design of new buildings. Recently ASHRAE published Standard 100-2015 Energy Efficiency in Existing Buildings. Other standards such as Standard 62.1 and Standard 55 also can be applied to existing buildings and are referenced by various sustainability and energy certification programs. What parts of these standards apply to existing buildings and how can facility managers use them to improve their operations? What other ASHRAE Standards, Guidelines, and Publications are available to improve sustainability of our existing building stock?

TECH SESSION 2A — 9:45 AM to 10:45 AM
Chris Mathis – How Long Will it Last? Addressing the Challenge of Sustainability

This lecture explores some of the roadblocks, pitfalls and opportunities on the road to truly sustainable buildings. It invites the audience to question long held assumptions and habits in building design, engineering and construction, and challenges how we assess numerous building performance attributes. From energy efficiency to durability to life expectancy, we will explore some of the challenges necessary to establish meaningful product and building performance metrics. We will examine how these sustainability objectives fit in with ASHRAE’s minimum code standards (90.1 and 90.2), green building standards (189.1 and 189.2) and others.

TECH SESSION 2B — 9:45 AM to 10:45 AM
Hoy Bohanon – How to Implement DCV and Comply with ASHRAE Standards

ASHRAE standards 90.1 and 189P require demand control ventilation in some instances. ASHRAE standard 62.1 allows demand control ventilation but places restrictions on its application. Many existing installations do not comply with the requirements of ASHRAE Standard 62.1. What is required and what strategies and technologies can be used to meet the requirements of the all the standards?

TECH SESSION 3A — 11:00 AM to 12:00 PM
Chris Mathis – Energy Efficiency in Commercial Bldgs

Advances in commercial building technologies have made possible dramatically greater levels of energy efficiency in commercial buildings than ever before. From new lighting, fenestration and glazing technologies, insulation innovations, air sealing, advanced HVAC systems and new diagnostic tools all create new opportunities for anyone working with 90.1 and the commercial building industry. This presentation will provide attendees with new information about commercial construction technologies for both new and existing buildings. It will also address opportunities and challenges in meeting new energy codes and the many “beyond code” programs such as LEED, Green Globes and other green building programs.

TECH SESSION 3B — 11:00 AM to 12:00 PM
Hoy Bohanon – Commissioning, Operating, Maintaining Air-to-Air Energy Recovery Systems

How does one commission energy savings equipment such as air-to-air energy recovery? What are key performance factors that must be measured? When can you simulate and when must you measure? Devices addressed include air-to-air energy recovery plates and wheels, desiccants, run around loops, and water-side economizers.

TECH SESSION 4A—1:45 PM to 2:45 PM
Julia Keen – Ethical Decision Making – An Exercise in Application

In lieu of the traditional lecture style presentation, this is a structured interactive exercise. The participant will be provided a copy of both the ASHRAE and the Professional Engineering Code of Ethics. A methodology for ethical decision making will be introduced. Realistic ethical dilemmas from the practice of building design and construction will be presented. Based on the information provided and using the provided Codes of Ethics the participants will be asked to make their own decision, discuss this with their table, and then be lead through the decision making process as a group. The ethical dilemmas begin as fairly simple black-white analysis and are progressively made more complex during the session.

TECH SESSION 4B—1:45 PM to 2:45 PM
Mick Schwedler – Chilled water systems for YEA: What the Gen Xers and Baby Boomers have done wrong
