Prathima Venkatesan Point of Sales Database Purpose Track inventory and donors in the Habitat resale store Increase the organization and maintainability of the resale store Status Completely functional Waiting to be integrated

Prathima Venkatesan Resale Store Resale store sells donated building materials not used by Habitat System must be intuitive so volunteers can be quickly trained

Prathima Venkatesan POS Database and Overview Keep track of donated and sold materials Donor name Item donated Item type Quantity Cost estimation Future additions to the database Bar-coding system Label printing system

Donnie Austin Energy Team Projects Set-back Thermostat Thermal Imaging Scan CO Testing Past Projects and Implementations

Donnie Austin Set-Back Thermostat  Programmable thermostats can lower energy use in home  Modeled in Energy-10 software package

Donnie Austin Set-Back Thermostat

Donnie Austin

Thermal Imaging Scan Requested by Habitat for Humanity of Lafayette to look at effects of changing insulation and drywall materials Two-story rehab house on Green Street evaluated with new and old wall materials

Donnie Austin Thermal Imaging Scan Slight improvement found (1-2°F) in walls Heat loss through windows, doors and corners (common)

Donnie Austin Carbon Monoxide Testing Problem Habitat was concerned that the design of the house was causing a problem with CO build up Dryer Exhaust may create a vacuum Hot water heater has an open flue House too ‘tight’

Donnie Austin Testing Tested two houses Max CO level was 3ppm Max allowable concentration in living area is 9ppm (ASHRAE) Testing concluded no CO problem in design Carbon Monoxide Testing

Donnie Austin Carbon Monoxide Testing Conclusion Possible for dryer to cause this problem If appliances are operating correctly and efficiently, no CO will build up

Donnie Austin Past Projects and Implementation Set-back thermostats in place Central air installed in all new homes

Brian Waller Team Conclusions Energy Team Setback Thermostat: $50 - $80 savings a year CO Testing No problem Thermal Image Scanning Great ability for the future

Brian Waller Team Conclusions Arch/Web Team POS Database Continuing next semester to completion Materials List Continually updated corresponding to each house Tutorials Updated, revised, and improved next semester
