Inventory pos and database

Keshav Prabhu

Edit Donor Information

Edit Store Stock

Resale Store Volunteer

Ring Up Customer

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


Resale store pos and database

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


Pos and database overview

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

Energy team objectives

Doug Crook

Energy Team Objectives

  • Five basic analyses were performed to reduce energy costs:

    • Cellulose vs. Fiberglass

    • Caulking wall joints

    • Attic fan

    • Window film

    • Future cost


Cellulose vs fiberglass

Assumptions

R-values

Cellulose: 38-40

Fiberglass: 31

Costs

Cellulose: $0.43 (labor + material)

Fiberglass: $0.41 (material)

Payback period

Approximately 1.5 years

Doug Crook

Cellulose vs. Fiberglass


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

Caulking Wall Joints


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

Attic Fan Analysis


Window film analysis

U-Value = 0.45 Btu/hr-ft2-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

Window Film Analysis

Information provided by ASHRAE Handbooks, Manco Consumer Hotline 800-321-0253 and www.3M.com


Future cost analysis

Doug Crook

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
