Required Texts (choose 1 or more):

1) Lehto, M.R. & Landry, S.J. (2013) Introduction to Human Factors and Ergonomics for Engineers 2nd Edition, CRC Press.
(Note: This book but gives a foundation to the discipline and it is also a required text for DEA3510. Some of the HW questions may be based on information in this book).

2) Bridger, R. S. (2008). Introduction to Ergonomics, 3rd ed. CRC Press, New York and London.
(Note: This is more recent book that is less comprehensive on the foundations of the discipline but also more expansive. Buying a second-hand copy or one from a bookstore such as from Amazon may be the least expensive way to obtain this book. NOTE: The book is very 'English'. Some of the HW questions may be based on information in this book. This book is also a required text for DEA3510).

3) Sanders, M.M. & McCormick, E.J. (1993) Human Factors in Engineering & Design 7th ed., McGraw-Hill, NY.
(Note: This is an old book but still gives the best foundation to the discipline and is used for the professional certifying examination. Buying a second-hand copy or one from a bookstore such as from Amazon may be the least expensive way to obtain this book. NOTE: You do need the 7th Edition and not an earlier edition. Some of the HW questions may be based on information in this book. This book is also a required text for DEA3510).

Indoor Air Quality readings:

Recommended Text (for further interest)

Hedge, A. 2016. Ergonomic Workplace Design for Health, Wellness, and Productivity CRC Press.

(Note: This book includes chapters on environmental conditions but discusses ergonomics in the context of many physical settings. It is not essential for the course but gives the context for the broader application of course materials).

Course notes:

Course Description:

Human factors aspects of ambient conditions in indoor environments are addressed. Emphasis is placed on understanding both key concepts and measurement techniques. Coverage includes thermal conditions, ventilation and air quality issues, lighting, and acoustics as these affect the quality of the indoor spaces in which we live and work.

Course Objectives:

This course aims to familiarize students with the human factors information necessary for creating good indoor ambient environmental conditions. Upon completion of this course the student should understand:

  1. key concepts in each of the major topic areas covered i.e. indoor climate (thermal conditions, ventilation and air quality), indoor lighting, and indoor acoustics.
  2. measurement techniques and be familiar with methods.
  3. how to conduct a human factors analysis of an indoor environment.

Course Format:

The course meets twice each week for a total of three hours. This time will be used for a combination of lecture, discussion, and class work. Where appropriate, guest speakers may contribute to the course. Class readings will be assigned. Course performance will be assessed using two homeworks, and two exams - a prelim.  before spring break and a noncumulative final exam during finals week.

Grading Scheme:

The following grading scheme will be used:
