me if youmust. Fine for quick answers, to let me know that you are going to miss a class

2. Lecture Objectives Discuss the syllabus and ground rules
Describe scope of BES
Introduce the course themes
Introduce yourself
Address any of your concerns

3. Motivation for ARE 346N class
Who are you?
Why are you here?
What is your primary interest?
Structures
Construction engineering/Project management
Environmental Engineering
Building environmental systems (HVAC)
Something else

4. Structural vs. Environmental Systems in buildings4

5. 3D model – Biomedical Engineering (BME) Building5

6. 3D model – Biomedical Engineering (BME) Building6

7. 3D model – Biomedical Engineering (BME) Building7

8. 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?

9. Real world questions
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?

10. Buildings Responsible for ~40% of energy consumption
90% of our time we spend indoors
Construction is one of the largest industries in the world
Environmental systems are a central part of every building
Affect:
Energy consumption
Thermal comfort and IAQ
First cost

11. Course Objectives
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.
Define 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

12. Prerequisites Physics 103M and 303L ME 320: Applied Thermodynamics
I already took it
I have not taken it
I am currently taking it

13. Preparation for FE exam - Career in industry - step towards PE exam
Preparation for ARE 465
Capstone design seminar
Prepare you for BES portion
Background material
Resources
Calculation familiarity
Preparation for FE exam - Career in industry - step towards PE exam

14. Textbook
Tao and Janis (2004) 3rd or (2009) 4th Edition Too few examples
- I will add more
Some important area not adequately covered
- I will provide handouts
Very appropriate for those who want one textbook for ARE465 and won’t be doing BES after graduation

15. “References”
Trost, J., (1999), Efficient Building Design Series Volume 1: Electrical and Lighting, Prentice Hall.
Very good textbook
many examples
Cover only Lighting and Electrical systems
Library does not have it yet
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

16. “References”
Heating Ventilating and Air Conditioning Mcqusiton, Spittler, Parker (2000)
Common textbook for undergraduate HVAC class
Good descriptions
Many 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

17. “References” ASHRAE Handbook: Fundamentals.
IP or SI edition, hard copy or CD
In reference Library section
Note that it is much cheaper to become a member of ASHRAE to get this text.
Great and very complete reference
Few examples, very hard to read, inexpensive
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 - American Society of Heating, Refrigeration and Air-conditioning Engineers
- predominant BES Society
Inexpensive way to get textbook
Student Zone
For student application
