Time Series Analysis of Building Greenery Systems

Geun young Ahn

Abstract: Recently, greenery system is frequently applied on buildings and artificial grounds to improve urban ecological functionality. Green roofs can reduce surface water runoff, provide a habitat for wildlife moderate the urban heat island effect, improve building insulation and energy efficiency, improve the air quality, create aesthetic and amenity value, and preserve the roof's waterproofing. Specifically, architectural greenery is also known as an architectural language that can meet the sustainable design concept of architects. Therefore, this study is expected to establish the contemporary architecture as building, landscape architecture and the greenery technology. And this result will be used as a basic study to promote developing the advanced system based on the concept of consilience. The type of green roof system is generally divided into light-weight green roof and heavy-weight green roof and medium weight depending on building structure and permissible load of building in Korea. It is very important decision of green roof type for each building characteristics and properly management of green roof after construction. This study was conducted investigation of Index of Greeness and examining the time series for the final aim, landscape architecture conjunction simulation with building. It was carried out on five existing rooftop site from March in 2012 to October in 2013. Using CANON 450D with 18 ~ 55mm and Auto CAD ver.2010 program, landscape time series analysis of green roof were carried out. In this study, green roof planting type was divided into herbaceous plants group, shrub with herbaceous group and shrub and tree with herbaceous group. There was difference depending on management intensity in each type. Herbaceous plants group, is applicated generally low live-load building, had changes depending on irrigation management. Shrub with herbaceous plant group and arbor with herbaceous plants group, had differences by extensive or intensive management. Index of Greeness of two groups was recorded higher in intensive management than in extensive management, especially in summer and fall season.
