What is a major advantage of using a green roof?
A green roof has many benefits at economic, ecological and societal levels. A green roof provides a rainwater buffer, purifies the air, reduces the ambient temperature, regulates the indoor temperature, saves energy and encourages biodiversity in the city. Green roofs are part of climate-proof construction.

What is an extensive green roof?
Although there are no precise definitions of them, an extensive green roof has a shallow growing medium—usually less than six inches—with a modest roof load, limited plant diversity, minimal watering requirements, and is often not accessible.
Why are green roofs energy efficient?
Thermal mass and insulation In Australia, one of the most valuable energy benefits of green roofs is their ability to reduce summer cooling demands. Their contribution to insulating and shading buildings can help significantly in reducing energy consumption and greenhouse gas emissions.
What is a benefit to having a green roof quizlet?
Green roofs protect roofing membrane from exposure to ultra violet radiation and hail damage. reduce energy demand on space conditioning and greenhouse gas emissions. helps buildings stay cooler bc less heat flows into building, meaning less heat transferring to air above and keeping temps lower.
What advantages do green roofs provide over standard low slope roof treatments?
What advantages do green roofs provide over standard low-slope roof treatments? The soil barrier between the roofing and the sun allows for extra UV ray protection.
What is the difference between an extensive and intensive green roof?
This is the easiest way to remember the difference – an extensive green roof probably has a shallow layer of substrate that covers a large area, whereas an intensive green roof often has a deeper layer of substrate, confined to smaller areas. As the number and variety of green roofs has increased, so has the diversity.
What is extensive roofing?
Extensive landscaped roofs are an ecological alternative to conventional surface protection or ballast layers such as gravel and pavers. They are lightweight and have a shallow build-up height. Suitable plants include various Sedum species, herbs and some grasses.
What is the difference between extensive and intensive green roofs?
Extensive rooftops are a popular choice with homeowners, as they require very little maintenance. Intensive green rooftops have more than six inches of growing medium depth and can facilitate high plant diversity. They function in the same way as traditional gardens, however they are found at a higher level.
How do green roof reduce energy consumption?
Green roofs do provide potential energy savings by improving building insulation characteristics. However, the green roof system’s growing medium and plants modified the heat flow and reduced the average daily energy demand to less than 5,100 BTU (2 kWh) – a reduction of more than 75 percent.
What are the benefits of green roofs quizlet?
What makes a green roof green quizlet?

Green roofs are part of climate-proof construction.
What are the pros and cons of geothermal energy?
Geothermal energy is one of the most efficient renewable sources of energy. It’s essential to weigh the pros and cons of geothermal energy to determine whether it would be worth embracing it relative to the conventional energy sources. Early American Indians utilized hot springs as their primary source of hot water.
Why are geothermal power plants good for the environment?
One of the best geothermal advantages is that it is environmental-friendly. Since geothermal power plants involve no combustion, it does not cause carbon footprint which can result in environmental pollution. Research shows that an average geothermal power can release approximately 122kg CO2 for each megawatt (MWh) of electricity produced.
How long does geothermal energy last on Earth?
Geothermal energy is a source of renewable energy that will last until the Earth is destroyed by the sun in around 5 billion years. The hot reservoirs within the Earth are naturally replenished, making it both renewable and sustainable. 3. Huge Potential
