Energy-efficient housing is at the forefront of the real estate market today, but very few people understand that this goes beyond turning off the lights at night and using spray foam insulation. Dedicated architects always try to incorporate innovative new designs into their buildings, and more recently a popular technique called green roofing is beginning to make waves in the construction world.

A green roof is exactly what it sounds like - a roof covered in soil where green vegetation can grow. There are many different reasons a living roof might be included in a building design. These structures can absorb rainwater for consumption, provide a habitat to animals and even become a rooftop park for office building workers. However, these forms need to incorporate a sustainable design to function properly.

First, the respective roof must be covered in a waterproofing membrane that will act as a buffer between the soil and roofing surface. Once the soil is laid down, irrigation channels should be dug into the earth to ensure that larger plants receive enough water if rainfall does not provide an adequate amount. In low-maintenance gardens, this is not necessary, as most of the plants will be simple species like grass and moss.
