The aging of the building stock in most cities highlights the relevance of refurbishment to achieve sustainability. Current refurbishment practices are often short-sighted and do not encompass holistic strategies beyond energy saving. This research study aims to analyze the factors involved in roof refurbishment versus current decision-making determinants. The objective is to identify the barriers that hinder their implementation and to find arguments to support roof renovations. A multicriteria analysis, which considered environmental, economic and performance factors, was employed to select optimal roof refurbishment solutions. This study evaluated five solutions. With interviews held with construction professionals and a survey of experts and homeowners, the preferences and criteria for making decisions about roof refurbishments were analyzed. Simulation tools were then used to estimate the energy savings, payback periods and environmental impact for a representative building in the study area. The results were extrapolated to a neighborhood level. The results highlight the importance of considering factors, such as weight, cost and user preferences when selecting suitable refurbishment solutions. The findings not only estimate the potential energy savings and carbon emission reductions in the area but also underscore the relevance of roof refurbishments for prolonging a building’s life span to contribute to sustainability.

“…Almost all of these green roofs aim to improve indoor thermal environment of midsummer (Iijima 2008 (Pearlmutter and Rosenfeld 2008). In contrast, the watered-soil layer on a roof can indeed be used as an effective means of evaporative cooling and has the particular benefit of producing this cooling during the hottest hours (Al-Turki et al 1995;Pearlmutter and Rosenfeld 2008). In addition, plants in green roofs prevent watered-soil from evaporating for cooling.…”

Urban green spaces, which are important for human and wildlife in the urban area, have changed into man-made spaces. Increased urbanisation has had and continues to have a negative impact on urban green spaces, and affects the urban microclimate as represented by 'Urban Heat Island (UHI)' phenomena. Especially, habitat fragmentation can be extreme within urban ecosystems, and fragments of natural vegetation may be too small or even too isolated to support some species. Therefore, the networks, which offer habitats and corridors that help conserve biodiversity, are also important to maintain the ecological services of a sustainable urban landscape, as well as total green area. However, there are rarely enough open spaces due to urban densification. This is why rooftops of buildings, which had not previously been regarded as spaces for planting for vegetation, have been utilised as a type of open space, and so green roofing has become one of the gradually developing fields of urban ecological engineering. This present paper aims to explore the potential of rooftops as habitats of urban wildlife comparing cases in Japan and UK, and pave the way for a preservation of urban biodiversity under restricted urban environmental conditions. As a result, it was suggested that Japanese green roof industries consider the concept of brown/biodiverse roofs instead of extensive roofs with sedum or lawn. At the same time, intensive roofs should be efficiently installed to provide 'stepping stone' in urban areas not having enough open space. If possible, however, to create habitats on the ground is more preferable than on the rooftop due to accessibility. Finally, if impervious spaces (e.g., concrete and asphalt) are replaced with pervious spaces (e.g., green area or brownfield), it is significant for not only urban biodiversity but also UHI.
