2. CPS demonstration 1) What is my dog’s name? Sparky Rex Fido Spot
Garfield

3. Motivation Who are you? Why are you here?
2) What is your primary interest?
Structures
Construction engineering/Project management
Building environmental systems (HVAC)
Design/CAD
Something else (specify)

4. Real world questions
It is 4pm on the day before you need to submit the plans. Your mechanical engineer comes to you and tells you that that the structural change that you approved will cost $50K in additional ducts and equipment. What do you do?
A salesperson tells you that changing your dropped ceiling and roof insulation strategy is guaranteed to save you 1/3 of your building energy costs. Your roofing contractor tells you that it is impossible to build the roof in the specified manner without causing moisture problems. Who should you believe?

5. Buildings Responsible for ~35% of energy consumption
90% of our time is spent indoors
Construction is one of the largest industries in the world
Environmental systems are a central part of every building

10. Course Objectives By taking this class you will be able to:
Describe the role of building environmental systems in building planning and design
Research and critically analyze claims about building environmental systems made by salespeople, subcontractors, and building designers
Calculate building heating, ventilating, and air conditioning loads and specify HVAC equipment for residential and light commercial construction.
Acquire design requirements for building electrical systems and design basic systems
List characteristics of different lamps, describe building lighting designs and their consequences and demonstrate knowledge of lighting design principles
First is overall theme – relevant to everyone
2nd also relevant to everyone
example of mechanical engineer resisting your change
Project manager- knowledge of planning for BES stages
4 main areas – HVAC, electrical, lighting, plumbing
Noise control and acoustics – if we have time

11. Preparation for ARE 465 Capstone design seminar
Prepare you for BES portion
Background material
Resources
Calculation familiarity

12. “Textbooks”
Trost, J., (1999), Efficient Building Design Series Volume 1: Electrical and Lighting, Prentice Hall.
CPS remote. Available for checkout from the library or for purchase from the bookstore.
Textbook: Tao and Janis
-Good reference source
-(relatively inexpensive)
-fewer errors
Stein and Reynolds- comprehensive, but many errors
BES bibliography – continuously adding to the list with commentary
ASHRAE – professional organization – the reference

13. Why CPS?
Educational literature suggests that it improves student learning
ASEE paper
Student responses in CNS indicate it helps learning
Active, participatory classroom
(students, UT)
Class Key: R2710P487
Serial Number: From Remote (i.e. 1030F4)

14. Dr. Siegel should use CPS for this class in the future

15. 5) Have you used CPS in a class at UT before
Yes in Physics
Yes in Engineering
Yes in something else No

16. Textbook for HVAC portion of class
No ideal textbook
You need to get one of the following three books

17. ASHRAE
2001 ASHRAE Handbook: Fundamentals. IP or SI edition, hard copy or CD
In reference section of Engineering Library
1997 editions on 2 hour reserve
Note that it is much cheaper to become a member of ASHRAE to get this text.
We will use IP units
Great and very complete reference
Few examples, very hard to read, cheap (to ASHRAE student members)
Most appropriate for those who want the industry-standard reference and intend on having BES be a part of their future

18. ASHRAE Membership ASHRAE is predominant BES Society
IESNA, NFPA
Cheap way to get textbook
Student Zone
Student application
Needs my signature (part of assignment zero)

19. Tao and Janis (2004) 3rd Edition
Just arrived in July
Improved over previous version, but still far from perfect
Some (but not enough) examples
Some outdated material
Some confusing descriptions
Some incorrect (or hard-wired) formulae
Good complement for Trost textbook for first portion of class
Most appropriate for those who want one textbook for ARE465 and won’t be doing BES after graduation

20. Mcqusiton, Spittler, Parker (2000)
Common textbook for undergraduate HVAC class
Good descriptions
Most examples
Much more in-depth than we will use
Not used for HVAC design classes here at UT
You should get this if you want a readable text on HVAC and have the initiative to fine the relevant sections yourself
Complements ASHRAE Fundamentals
