Making a House Green
Ali KnaakHonors Research Project
Fall 2009
To discover the most effective changes that can be implemented in a home to minimize environmental impact while still considering budgetary constraints
Collect and clearly report information on how specific investments effect energy bills and environmental impact; specifically the carbon footprints
use the data collected to educate the public and students at Presbyterian College about energy and sustainability
Objectives
Current Energy Sources
Alternate Energy Sources
Current Energy Usage
Alternate Energy Usage
The Moorefield House
30 year ‘pay off’ time period set Seven years is the standard for average homeowner
Inflation

Criteria for Environmental Analysis of the House
Ways to analyze the environmental impact are various and vast
Our definition only accounts for the carbon emitted during manufacturing and use
1kg of carbon = $0.2
