“…The results indicate that green stratigraphy increases the thermal inertia on a traditional building, also, the thermal inertia of the opaque envelope of the air-conditioned buildings has a high influence on the energy transfer through the roof or wall in dynamic conditions [24] Green roofs provide a wide range of sustainability and ecological benefits while also enhancing the aesthetic qualities and architectural presentation of buildings [19]. Green roofs, like other sustainable strategies, have been successfully used in many countries around the world [25][26][27]. Studies have shown the effectiveness of green roofs in hot climates as well [28].…”

Green roofs may be considered a passive energy saving technology that also offer benefits like environmental friendliness and enhancement of aesthetic and architectural qualities of buildings. This paper examines the energy and economic viability of the green roof technology in the hot humid climate of Saudi Arabia by considering a modern four bedroom residential building in the city of Dhahran as a case study. The base case and green roof modelling of the selected building has been developed with the help of DesignBuilder software. The base case model has been validated with the help of 3-month measured data about the energy consumption without a green roof installed. The result shows that the energy consumption for the base case is 169 kWh/m 2 while the energy consumption due to the application of a green roof on the entire roof surface is 110 kWh/m 2 . For the three investigated green roof options, energy saving is found to be in the range of 24% to 35%. The economic evaluation based on the net present value (NPV) approach for 40 years with consideration to other environmental advantages indicates that the benefits of the green roof technology are realized towards the end of the life cycle of the building.

Sustainable drainage system site assessment method using urban ecosystem services

2016

The United Kingdom's recently updated approach to sustainable drainage enhanced biodiversity and amenity objectives by incorporating the ecosystem approach and the ecosystem services concept. However, cost-effective and reliable methods to appraise the biodiversity and amenity values of potential sustainable drainage system (SuDS) sites and their surrounding areas are still lacking, as is a method to enable designers to distinguish and link the amenity and biodiversity benefits that SuDS schemes can offer. In this paper, therefore, the authors propose two ecosystem services-and disservicesbased methods (i.e. vegetation structure cover-abundance examination and cultural ecosystem services and disservices variables appraisal) to aid SuDS designers to distinguish and link amenity and biodiversity benefits, and allow initial site assessments to be performed in a cost-effective and reliable fashion. Forty-nine representative sites within Greater Manchester were selected to test the two methods. Amenity and biodiversity were successfully assessed and habitat for species, carbon sequestration, recreation and education ecosystem services scores were produced, which will support SuDS retrofit design decision-making. Large vegetated SuDS sites with permanent aquatic features were found to be most capable of enhancing biodiversity-and amenity-related ecosystem services. Habitat for species and recreation ecosystem services were also found to be positively linked to each other. Finally, waste bins on site were found to help reduce dog faeces and litter coverage. Overall, the findings presented here enable future SuDS retrofit designs to be more wildlife friendly and socially inclusive.

“…Biodiversity roofs tend to use both plug-plants and seeds and often support local species that naturally invade the roof (Bates et al 2013) such as Buddleia, Chenopodium spp., Trifolium spp., tree species seedlings (Salix spp.) and various grass species.…”

“…These roof level habitats often naturally retard succession due to limitations of substrate depth, water holding capacity and nutrient availability (Olly et al 2011. However, such stresses might also maintain a higher biodiversity level if managed effectively (Benvenuti 2014), as dominating species can be removed (Bates et al 2013). …”
