Brittany Heyman, Michael Weinstein, Benjamin Veilleux, and Michael Collins
3. Types of Green Roofs
Extensive
Require less maintenance
Able to be planted on sloped
roofs
Restricted to hardy
vegetation
Require a lesser initial
investment
Intensive
Require more maintenance
Require more structural
support
Flexibility in vegetation
choices
More cost effective in the
long-run
6. Energy Savings
Heat Island Mitigation
Block solar radiation in
summer
Trap heat in winter
Reduce heating and
cooling costs by
thousands of dollars
8. Service Life
Service life doubled by way of:
Reduction of expansion/contraction
Shielding from damaging UV rays
Protection from abrasion/physical wear
Reduced upkeep costs offset initial investment
9. Cost-Benefit Analysis
Higher initial installation cost
Lower maintenance cost
Saves cost in long term (heat retention)
Proportional relationship between roof area and cost savings
Tax deductible, whereas traditional roofs are not
