What is the heat island effect?
Dense urban areas can often be a lot hotter due to materials such as asphalt that absorb heat and re-emit that heat back into the surrounding area.
What are green roofs?
building roofs retrofitted with some form of garden covering the surface
What's novel about NU GREENS?
Our plan consists of not just gardens, but edible gardens, where produce could be sold in local farmers markets, increasing accessibility to fresh produce.
Why is roof runoff bad?
Roof runoff can contain chemicals and pollutants and pollute the surrounding environment.
How many degrees can a green roof lower the temperature of a building?
up to 27 °F
Who would take care of the rooftop gardens?
We would establish a group of caretakers, opening possibilities for new co-ops or service-learning class partnerships.
How much of human caused CO2 do plants absorb globally?
about 25-30%.
70%
How is this kept cost efficient?
Because our plan would use an extensive model of interlocking modules, it would only cost $8-12 per square foot, a much cheaper option than other models.
Hot hot can Boston rooftops get in the summer?
150 °F or higher - this contributes to the heat island effect.
Why are green roofs important?
What types of plants would we use?
Hardy plants, such as legumes and nightshades!
How many tonnes of CO2 does cooling buildings emit annually?
The IEA estimated that, in 2022, this was around 1 billion tonnes.
What other universities have started green roofs?
Carnegie Mellon and Penn State (and others, too!)
Would NU GREENS have a return on investment?
Yes! In 6 years, Northeastern would experience a return on investment (ROI) with our plan.
