Session #1 – ASHRAE Standard 189.1 and the International Green Construction Code

ASHRAE, in conjunction with the U.S. Green Building Council and the Illumination Engineers Society, developed Standard 189.1 for the Design of High Performance Green Buildings with the initial release occurring in 2010.  The Standard provides the minimum requirements for a high-performance green building, and was developed with the intent to provide a balance of environmental factors involved with designing, building, and planning for the operation of buildings.  Since the initial release, the Standard has continually evolved as a result of changes in the industry and in relation to other Standards such as 90.1 This session provides a detailed summary of the key changes that are being incorporated in the release of the 2017 version of Standard 189.1 and how this Standard will relate to the International Green Construction Code with the 2018 code cycles revisions.

Session #2 – CO2 Monitoring for Outdoor Airflow and Demand-Controlled Ventilation

A number of programs and standards that exist for buildings today specify the use of outdoor air monitoring.  Monitoring is to be done either based on CO₂ levels in the occupied space or actual measurement of outdoor airflow, depending on the space design occupancy and ventilation type (mechanical or natural).  Current standards or program descriptions do not provide detailed guidance for determining what level of CO₂ should be considered the maximum concentration to expect, and those that do provide guidance are generally based on a single value above the ambient concentration.  This session describes how to determine a level for CO₂ concentrations for an outdoor airflow monitoring program or as part of the upper control limit for a demand-controlled ventilation system.

Session #3 – Thermal Comfort as Related to Energy Consumption: What is the Balance?

Maintaining thermal comfort within an occupied building requires energy, thus optimized solution methods for balancing energy use with indoor environmental quality (adequate thermal comfort, lighting, etc.) are needed. Current building temperature control systems do not adequately take in account the adaptive capability of the occupants, but this concept can be used advantageously during implementation of demand response. Demand response programs commonly include temporary adjustments to space temperature set points and thus can affect the occupants’ thermal comfort perceptions. How to balance out the overall energy consumption and peak demand for cooling or heating within buildings with the need for maintaining adequate thermal comfort in the built environment is an issue important to system designers, building operators and society as a whole. This session provides an overview of the historical development of thermal comfort perception, the two primary approaches used to predict and evaluate thermal comfort, and how these are incorporated in ASHRAE Standard 55. Also covered is a discussion of how thermal comfort considerations can be factored into demand response measures, addressing the conflicting balance between energy consumption and thermal comfort, and a vision on how to possibly achieve an overall optimized balance.

Each Session is worth 1 PDH.

Program

• Presentation: The Interface Between Risk and Ethics
  The topic of ethics has always been difficult to address because ethics is often seen as fluid and difficult to quantify. The fluid nature of ethics is generated by the wide spectrum of individual perspectives, coupled with highly variable cultures and situations, thus making ethical decisions difficult to predict. Risk has many of the same attributes in that it can also be very fluid and difficult to measure or predict. The presentation looks at the relationship between risk and ethics while exploring some ways to place both into a common context so that viable strategies can be developed for both the firm and the individual.

Presenter

Presenter: Tim Wentz (ASHRAE Distinguished Lecturer and past ASHRAE President)

Tim is an Associate Professor of Construction Management at the University of Nebraska – Lincoln, where he teaches a wide spectrum of courses, including environmental systems, mechanical estimating, mechanical project management, professional practice/ethics and the senior capstone course. Tim’s professional focus is in teaching and undergraduate education, where he has participated in numerous committees and initiatives. He currently serves as an advanced team leader for the Peer Review of Teaching program, a College representative on the Student Success task force and is also currently chair of the College of Engineering Curriculum and Academic Standards Committee.

Tim has served the Society in many different capacities. He started his ASHRAE career in 1976 after graduating from the University of Nebraska and worked in a grassroots capacity for many years. He is a past president of the Nebraska Chapter, past RVC of Student Activities for Region IX, past DRC of Region IX and as Society president in 2016-2017. Tim also serves as Faculty Advisor of the Mechanical/Electrical Specialty Contractors (MESC) student chapter, which is an umbrella student chapter co-sponsored by ASHRAE, the Mechanical Contractors Association of America  (MCAA) and the National Electrical Contractors of America (NECA). He received an ASHRAE Technology Award in 1987, Region IX Chapter President of the Year, Region IX Hall of Honor in 2005, E. K. Campbell Award of Merit for Teaching in 2000, the Distinguished Service Award in 2013 and the Exceptional Service Award in 2015. Tim was named an ASHRAE Fellow in 2005.

Tim has also been very active in the Mechanical Contractors Association of America (MCAA), where he has served as a trustee for the Mechanical Contractors Education and Research Fund (MCERF) and is currently a member of the National Education Initiative (NEI) faculty and also on the Institute for Project Management (IPM) faculty. He was named the MCAA ‘Educator of the Year’ three times (2000, 2002 and 2004) and in 2009 was the recipient of MCAA’s highest award, the Distinguished Service Award, the first academic to receive the award.
