1. Energy Saving Climate Control System (ESCCS) Team: Sean Jacobs, Brad Nissenbaum, Colin Tracy Advisor: Professor Anderson

2. Mission Statement Environmental - Relieving stresses caused by increasing energy demands Economic - Saving the consumer money through decreased energy use Engineering - Use sound engineering practices in order to meet goals and satisfy consumer demands.

3. System Outline Temperature is measured Based on User Settings, Room Environment is adjusted Control system is used to adjust fan operation, lighting, and electrochromic glass Thermostat and User Input dials Control System Monitors and Adjusts Room with Electrochromic glass climate and light changes

4. Deliverables A model enclosure demonstrating the functionality of the ESCCS All documentation regarding circuit schematics, parts list, testing results and project costs User’s manual

5. System Block Diagram

6. System Logic

7. Description of System Logic After initialization, the current temperature is measured. The user temperature is compared to the current temperature, and the next action in order to meet the desired temperature is decided based on this comparison. Wait times are incorporated in order to take into account small temperature changes.

8. MDR Deliverables Assembled test enclosure with sensors Interior lighting PV panel Ventilation fan Some preliminary test data Refined plans for remainder of project

9. Assembled Test Enclosure Our test enclosure is fully assembled with lighting and fan installed. The sensors have been selected, and we can begin initial testing of heat levels in our prototype living space.

10. Enclosure Design and Materials Polyisocyanurate foam insulation sandwiched between ¼ inch plywood. 70 Dergee tilt on front panel

11. Power system We decided that in order to minimize our expenses, we would recycle the solar panel and charge controller from an SDP project from two years ago.

12. Sensor Selection Our temperature sensors were selected with desired temperature range of 5-35 C with a small error and a low power consumption. Sensors are digital.

13. Microchip Selection Our microchip was selected with low power but with enough pins to collect all necessary data and comparators to calculate the needed changes for our system.
