Green Roofing and Sustainable Practices
Green Roofing and Sustainable Practices
Green roofs are an eco-friendly construction technique that incorporates soil substrate, vegetation, irrigation systems, root barriers and waterproof membranes into an integrated structure.
Conventional roofs allow rainwater to run off quickly, contributing to flooding and erosion while discharging untreated sewage into waterways. By contrast, green roofs slow rainwater runoff by allowing it to soak into the soil, encouraging evapotranspiration, and encouraging evapotranspiration.
Benefits
Green roofs feature layers of vegetation and soil which provide extra insulation, helping reduce energy costs and extend membrane lifetime by shielding from direct ultra-violet radiation.
Green roofs help decrease rainwater runoff into sewer systems and thus decrease water waste, while filtering and purifying storm water, helping prevent pollutants from seeping into other streams or bodies of water.
Green roofs provide many environmental and economic advantages, as well as additional value to a building and its surrounding community. Aside from providing peaceful shelter for birds, insects and wildlife alike, they also add value to a building by increasing property values in its vicinity. Green roofs can also provide food-growing plants such as herbs and vegetables for restaurants that prefer farm-to-table delivery over refrigerated freight trucks or planes for their food deliveries; furthermore providing recreational spaces for residents who can utilize an additional outdoor area for recreation purposes.
Installation
Green roofs must provide drainage and protection with waterproof membranes, while supporting plants, irrigation systems, irrigation controllers, root barriers as necessary – while remaining as lightweight as possible.
Extensive green roofs typically consist of an extensive soil base made up of two to six inches of compost that provides the foundation for grasses, sedum (water-storing succulent plants), wildflowers and mosses suited to living on roof environments.
Intensive green roofs use deeper soil layers – sometimes up to three feet or one meter deep – in order to accommodate shrubs, bushes, and trees. These green roofs often take on the appearance of gardens; creating a place where people can relax or host events. Furthermore, intensive green roofs can also be used for growing vegetables, herbs, fruit trees, as well as for growing organic produce for restaurants aiming towards carbon neutral farming-to-table models.
Maintenance
Green roofs can help mitigate the urban heat island effect by absorbing rainfall and cooling the environment, as well as provide habitat and food sources for native plants, insects and wildlife.
Water quality improvement strategies include reducing stormwater runoff and increasing infiltration rates, as well as decreasing energy needed for cooling and heating buildings, greenhouse gas emissions, air pollution levels, and health concerns related to heat exposure.
Assuming your green roof requires regular inspection and cleaning, most maintenance can be accomplished through periodic cleaning and inspections. This should include clearing away any weeds or fallen leaves, checking whether the growing medium is undamaged, feeding once annually in March/April to provide plants with all of the nutrients they require, as well as inspecting an irrigation system to detect leakages that could occur due to overwatering of dense soil or extra strain on membrane.
Sustainability
Green roofs play an integral role in sequestering carbon and mitigating urban heat island effects. Evaporative cooling through plant transpiration and solar evapotranspiration helps lower cooling loads while providing habitats for birds, insects, and other forms of wildlife.
A green roof typically comprises multiple layers: water retention and drainage layer, waterproof membrane, root repellent layer, growing medium layer, filter cloth filter cloth thermal insulation thermal insulation support structure support structure support structure support structure roof support structure system that enables plants to thrive without causing structural damage to its roof support structure. This layering system allows plants to flourish freely without impacting structural integrity of roof support structure.
Green roofs can include anything from grass, drought-tolerant flowers, herbs or full-scale gardens of shrubs, trees and vegetables – perfect for restaurants that wish to adopt locally produced, fresh farm-to-table food rather than depending on refrigerated freight trucks or airplanes to bring supplies in. Rooftop gardens also present opportunities for community gardens that help decrease dependency on imported food while simultaneously increasing levels of social cohesion and self-reliance within cities.
