ABSTRACT
Due to urbanization and industrialization, increased population is leading to shortage of green spaces. Due to
this the world started facing some problems such as – Urban heat island, carbon foot print, storm water runoff
etc. Living roofs and walls significantly contribute to sustainability by increasing energy efficiency of a
building, helping our cities to mitigate the effect of heat island, provide sound insulation, give us a new ecology
for various species and turn the wasted roof into various types of amenities. They are emerging as important
addition into the palette of construction techniques. This paper shows the benefit of Living roofs and walls over
conventional roofs and walls. Although Living roofs are initially more expensive to construct than conventional
roof, they can be more economical over the life span because of the energy saved and the longevity of roof
membranes. Green roofs are considered as a solution to improve the urban environment and are an ideal tool as
the building choice to increase the environmental sustainability in urban setting. This paper aims to deal with
living roof and wall techniques based on the strategies of sustainable development in architecture and its
impact on environment and finding solution to the barriers in implementation of living walls and roof.
Keywords : Environmental Sustainability, Living Roofs, Living Walls.
I. INTRODUCTION
Living roofs and walls plays an important role in
sustainability through its contribution to the natural
ecosystem. The objectives of this study are to identify
the barriers in implementation of green roofs and
walls and finding out suitable solution to these barrier
while implementation. Removing these barriers will
contribute not only to the aesthetics but also to the
environment.
A. Evolution of Vertical Landscape
History revels that purpose of vegetated roof were
diverse. The earliest documented garden in the 7
th
century B.C. was the hanging garden of Babylon In
Mesopotamia, near river Euphrates. They are called
Hanging Garden because of plants hanging down over
the year and looks like floating in the air. In more
recent times, Green roof were seen to be as turf roof,
which provide insulation and it keeps their home cool
in summer and warm in winter. After a lot of
researchers taken place, this phenomenon was
developed in Germany in 1960 which really help on
understanding green roof. After this, further research
on different components was carried out including
studies on root repelling agents, water proofing
membrane growing media, drainage etc. In India the
concept has gained popularity only in the
metropolitan cities where the horizontal spaces are
not meeting the environmental needs.
