However, little is done to design this surface to benefit the public sphere. Instead, the facade of a building performs either as a component that focuses only on the quality of comfort for interior occupants, while ignoring effects on the exterior of the building, or as an identifiable aesthetic for the building＇s owners, This essay proposes the rethinking of the building facade as a steward of outdoor pedestrian welfare, and the conception of public health as an added function of the building envelope- a concept that may fall into the jurisdiction of public works. If the huge total surface area of a city＇s buildings is thought of as part of the city＇s infrastructure, then its public contribution may not only make outdoor areas comfortable, clean, and enjoyable, but also help to alleviate the bigger problem of rising temperatures in cities.展开更多

With the aggravation of city pollution, construction of ecological corridor has been put on the agenda of urban ecological construction, against this background, "2 rings and 17 radial lines" of Zhengzhou City were planned. This paper analyzed the plan from the perspectives of role of urban green corridor, planning principle, characteristic building and greening of building facade, and exploration of green corridors integrating pathways, bikeways, bus harbors and green island gas station.展开更多

In this view, maintenance has functional value and greatly contributes to increasing quality in environments. With reference to maintenance phase and residual value of building products upon dismantling, the present manuscript investigates a set of technological packages of quality and technical value referred to two alternative facade systems available for recovery actions on Italian council buildings--the ETICS （external thermal insulation composite system） and the external cladding system--complying with one thermal-insulation strategy, but different in terms of service life duration. Preservation of technical value and value increases are strictly related to maintenance quality and efficiency. Volume of investments in maintenance is not the only parameter to be considered to assess facade-system-management quality. Time-accurate economic assessment requires the entity to be related to periodical checks on performance quality in the building system and in its parts. Effective technical data to draw up consistent estimates and appraisals are rarely available in literature. With all that stated above, the present manuscript aims at introducing technical data related to drawing up reliable cost estimates and effective appraisals in terms of economics, quality and environmental sustainability. Conclusions will be drawn from the end of the manuscript.展开更多

Since the interest restoring the environmental integ- rity of urban areas continues to increase, new developments in construction practices with beneficial environmental characteristics take place, as vertical greening systems. Applying green fa?ades is not a new concept and can offer multiple benefits as a component of cur- rent urban design;considering the relation be- tween the environmental benefits, energy sav- ing for the building and the vertical greening systems (material used, maintenance, nutrients and water needed) the integration of vegetation could be a sustainable approach for the enve- lope of new and existing buildings.展开更多
