The Benefits Of a Roll-Out Green Roof

As either an architect or building owner, installing a roll-out green roof is an excellent way to improve a building’s visual appeal and reduce energy consumption while contributing to maintaining a healthy, green environment.

Green roofs employ water-wise gardening practices that capture and store rainwater on their surfaces, delaying its discharge into the sewer system and keeping waterways cleaner. This reduces peak loads on the sewage system while keeping peak loads to a minimum and keeping waterways cleaner.

Energy Efficiency

Green roofs can help reduce energy use, as vegetation helps lower building cooling loads and enhance thermal insulation, leading to significant savings on heating and cooling bills, saving both money and energy for utility systems.

Green roofs can help significantly decrease stormwater runoff by absorbing and retaining rainwater, helping reduce flood risk while decreasing storage requirements in sewer systems.

Green roofs can help reduce air pollution and greenhouse gas emissions by reducing power and cooling consumption while providing numerous health benefits for city dwellers by filtering out particles that contribute to asthma attacks or respiratory ailments.

For this study, 42 simulations were run across 6 cities worldwide (Almeria, Burgos, Madrid, Las Palmas de Gran Canaria, Seville and Barcelona) using both models A-B-C as reference models and two refurbishment scenarios: simply roofing replacement or an all-inclusive renovation of the thermal envelope.

Water Savings

Green roofs can capture and filter stormwater before it enters the environment, helping reduce combined sewer overflows, pollution levels, and flooding.

Green roofs differ from their conventional counterparts in that they take more time to absorb rainwater, thus slowing runoff. Furthermore, green roofs filter and trap pollutants such as phosphorous, nitrogen and cadmium.

Reducing air temperatures also helps control urban heat islands and bring down energy demand in the summertime.

A typical green roof consists of layers of plants, growing medium, filter fabric, drainage layer, root barrier and waterproof membrane, as well as leak detection and monitoring systems.

Reduced Noise

Roll-out green roofs add not only aesthetic value to buildings, but they can also help provide a more peaceful atmosphere by dampening noise from outdoor sources like aircraft, traffic and construction sites. Furthermore, green plants have been proven to help reduce tension and stress for residents within buildings.

Green roofs can also help improve air quality by reducing particulate matter and nitrogen oxide concentration in urban environments, as well as mitigating against “heat island” effects on buildings.

Studies have demonstrated that green roofs can reduce sound by 10 decibels compared to non-green roofs, thus increasing productivity while decreasing stress and other negative side effects for employees working in buildings with them.

Reduced Maintenance

Installing a roll-out green roof onto your building provides many advantages, including decreased maintenance costs and increased reliability.

Green roof maintenance includes regular weed control, fertilization, irrigation and plant replacement costs that can add up over time. However, these expenses can be offset by selecting appropriate plants and installing them properly.

Succulents make an ideal addition to roof gardens as they require very little water and soil for growth. Their low maintenance needs mean this easy-to-install option will save money over time.

An economical and eco-friendly option to add green roofs to any building is using sedum rolls. These pre-grown mats can easily be unrolled on top of the roof and cut to size if necessary, providing an economical yet eco-friendly roofing solution. Suitable for use in both commercial and residential buildings looking to reduce maintenance costs and create an environmentally-friendly roofing solution.
