ROOF GARDEN A terrace garden is a garden which is established on a terrace, roof, or patio, usually in a house where there is limited gardening space. These types of terrace gardens are especially popular in urban areas. (www.wisegeek.com) • Terrace gardens are commonly created at three different levels, which are: • On rooftop of a building. • Porches, window boxes, portico , balconies and such projected levels out of tower block, above the ground level • At the podium level, around the base or on roof of large basements. • The introduction of vegetation/ greenery in the urban fabric may help to relieve the ill effects of Urban heat island effect, pollution, global warming etc. • Green roofs – “Terrace Gardens” bring green spaces into urban areas while offering thermal benefits and energy savings for the user. • A major reason for the need of the terrace garden is the contribution they make to the building insulation and energy savings. UTILIZATION: •Planted roofs at the individual and the organizational level may become places of recreation.
• Extensive EXTENSIVE ROOF • Thin growing medium; little or no irrigation; stressful conditions for plants; low plant diversity. Overall depth:70-120mm Weight max:80-125kg/sq.m
Advantages: • Lightweight; roof generally does not require reinforcement. • Suitable for large areas. • Low maintenance and long life. • Often no need for irrigation and specialized drainage systems. • Often suitable for retrofit projects. • Can leave vegetation to grow spontaneously. • Relatively inexpensive. • Looks more natural. Disadvantages: • Less energy efficiency and storm water retention benefits. • More limited choice of plan.
• Intensive NTENSIVE GREEN ROOF • Deep soil; irrigation system; more favourable conditions for plants; high plant diversity; often accessible. Overall depth:150-1500mm Weight max:200kg/sq.m I
Advantages: • Greater diversity of plants and habitats. • Good insulation properties. • Can be made very attractive visually.
