Architectural Team Objectives Materials list program POS and database program Keshav Prabhu

Program Attributes Capabilities – Many different styles of homes – Cost comparison between vendors Limitations – Electrical, plumbing, and HVAC Keshav Prabhu

Materials List Input Keshav Prabhu

Materials List Output Sections – Quantity buy – Quantity O/H (out of house) – Material description – Piece cost – Total cost Keshav Prabhu

Inventory POS and Database Purpose – Track inventory in the Habitat resale store – Track material donors – Provide user with point-of- sale terminal functionality Status – Gathering requirements – Creating tables in database Edit Donor Information Edit Store Stock Resale Store Volunteer Ring Up Customer Keshav Prabhu

Resale Store POS and Database Resale store sells donated building materials not used by Habitat Inventory tracking and cash register system is required System must be intuitive so volunteers can be quickly trained Keshav Prabhu

POS and Database Overview Keep track of donated materials – Donor name – Item donated – Quantity – Cost estimation PC used to run database and cash register applications – Cash register application will modify database and track sales – Handheld barcode reader – Label printer Keshav Prabhu

Energy Team Objectives Five basic analyses were performed to reduce energy costs: – Cellulose vs. Fiberglass – Caulking wall joints – Attic fan – Window film – Future cost Doug Crook

Cellulose vs. Fiberglass Assumptions – R-values Cellulose: Fiberglass: 31 – Costs Cellulose: $0.43 (labor + material) Fiberglass: $0.41 (material) Payback period – Approximately 1.5 years Doug Crook

Caulking Wall Joints Assumptions – Reduces air infiltration by 15% Infiltration through walls accounts for 20% of total infiltration No reduction in R- value of insulation $30 to caulk a house Results – Average Savings = $10.27 Doug Crook

Attic Fan Analysis Assumptions – Flat roof (no tilt), no solar absorption – Ambient temperature Results – Reduction of air conditioning energy costs = $14.50 – Operating cost = $30 – Modification not recommended Doug Crook

Window Film Analysis U-Value = 0.45 Btu/hr-ft 2 -F U-Value dependent upon distance between window and film Simulated from Nov 1 to March 1 $8.97 per roll of film Average of $27 per home (3 rolls) Reoccurring cost each year Doug Crook Information provided by ASHRAE Handbooks, Manco Consumer Hotline and

Future Cost Analysis: Natural gas price outlook:.2% cost decrease per year Electricity price outlook:.5% cost decrease per year Electricity consumption outlook: 1.1% increase per year Source of information: linked from Doug Crook

Future Cost Analysis: Typical Habitat for Humanity house showing total analysis (both electrical and natural gas combined) for current and future energy costs. Doug Crook
