Ecological & Environmental Benefits
With beneficial impacts on biodiversity, energy consumption, climate change mitigation, reduction of Albedo / Urban Heat Island Effect (UHIE), air and water quality, society derives significant short- and longer-term ecological benefits.
Green roofs can provide food, habitat, nesting opportunities or resting places for creatures displaced by urban development, such as spiders, beetles, butterflies, birds and other invertebrates - replacing lost habitat and potentially aiding planning applications.
The vast array of planting species that Blackdown are able to accommodate in the green roof design enables the green roof to blend into the surrounding natural environment, replacing the building's footprint.
Runoff quality is improved by reducing the velocity of runoff - mitigating erosion and restricting collected pollution - and by filtration of pollutants by the substrate, reducing pollutant seepage into ground waters.
Offsetting Carbon Emissions & Improving Air Quality
As vegetation consumes carbon during photosynthesis, green roofs positively remove emissions, helping arrest climate change. Air pollution levels are also reduced by the green roof's ability to trap particulates and capture gases.
Urban Heat Island Effect
Temperatures are known to be higher in urban areas relative to surrounding rural areas, due to the higher quantity of impermeable, reflective surfaces and increased density of population. Green roofs reverse this effect by returning moisture to the environment through evapotranspiration, reducing solar gain and improving air quality.
Recycled Materials Usage
Blackdown's substrate recipes are engineered to provide the requisite air, water and nutrient balance. Recycled crushed brick is used within the typical recipes. Indeed, Blackdown can develop substrate solutions to minimise site waste on redevelopment sites.
The wide range of benefits that green roofs provide can support Primary, Secondary and Tertiary education in a variety of subjects; including science, art, technology, geography etc. With safe access and use provision included, a green roof can provide an outdoor classroom that reduces the need for off-site trips.
