1. Lecture Objectives: Discus Final Project Learn about Solar Systems
HW4 (final HW assignment)
HVAC system

2. Final Project Topics You need to form groups:
Maximum 3 members
Grad Students – individual projects
You need to visit me during this week
Office hours: Today, Wednesday, Thursday, and Friday
You need to prepare the project description
Till Tuesday next week (November 17th)

3. Final Project Topics Solar Systems Geothermal systems
Expand HW3 (PV and hot water)
Geothermal systems
Incorporated into the eQUEST
Building Envelope Optimization
Campus buildings, AEI competition, ….
HVAC systems
Lighting Systems
Specific building in eQUEST or other software
Modeling in matlab
Weep holes, attic temperature, façade systems,….

4. Solar hot water system

5. Geothermal Energy Systems (in combination with a cooling machine / heat pump)
Summer
Winter
In the summer, the earth acts as a cooling tower. The Cooling Machine loads the loop with heat, sending warmed water to be cooled by the earth
In the winter, the earth acts as the boiler. The Heat Pump extracts heat from the loop, sending cooled water to be warmed by the earth.

6. Envelope optimization
AEI Student Competition
A mixed use boiling in New York
Some other building, too

7. HVAC Systems Ventilation, Heat Recovery, Economizers,… AEI Student Competition Building or some other
Commercial buildings
Residential buildings
Saving % - depends on how much ventilation we have in the building

8. Results from Project 1 Example of building tune-up
A typical house in Austin New single family 2262 sf, 2-story home

9. Project Fixing Problematic Building at UT
Example of ECJ building

11. HW4 Solar systems

12. PV system
Silicon crystal base
Tin film

13. Hot Water Solar

14. HW4 Redefine house in Project 1 to be more realistic.
a) Find the optimum orientation and positioning angle for your PV solar collectors.
b) Size the PV system that will enable that your house became net zero energy house.
c) Add an electric hot water heater and calculate the new PV system size.
d) Size a hot water solar collector system for your hot water consumption.
e) Calculate the number of days when you need to use electric heater and how much energy is consumed by the backup electric heater.

15. eQUEST HVAC Models Predefined configuration (no change)
Divided according to the cooling and heating sources
