Criteria for GRIHA rating 69
BUILDING PLANNING AND
CONSTRUCTION
An integrated approach to building planning and construction is required to achieve maximum
benefi t in terms of the environment. Appropriate interventions at the design and construction stages
are critical to any sustainable building. These interventions lead to reduced demand for depletable
resources and effi cient resource utilization. Options for recycling and reuse of waste adds to the
sustainability of the building as a system.
Conservation and effi cient utilization of resources
Appropriate interventions at the planning and design stage can save valuable resources (water,
energy, and materials) throughout the life cycle of a building. The following criteria aim to ensure
saving such valuable resources.
Criterion 10 Reduce landscape water requirement
Objective
To reduce the landscape water requirement so as to minimize the load on the municipal water
supply and depletion of groundwater resources.
10.1 Commitment
10.1.1 Design the landscape so as to reduce water consumption by 30% or more (up to 50%).
10.2 Compliance
The following documents are to be submitted.
10.2.1 Narrative demonstrating water saving measures adopted in the landscape plan.
10.2.2 Plan indicating the plants list, nature of species, and area covered.
10.2.3 Calculation of the water requirement after establishment for landscape in LPD (litres
per day) for each month due to variation in PET (potential evapo-transpiration rate).
10.2.4 Provide cut sheets of the irrigation equipment showing technical specifi cations, such as
fl ow rate and dimensions.
10.3 Appraisal (maximum points – 3)
10.3.1 Reduction in water consumption by 30%, as per clause 10.2.3 (1 point).
10.3.2 Reduction in water consumption by 40%, as per clause 10.2.3 (1 point).
10.3.3 Reduction in water consumption by 50%, as per clause 10.2.3 (1 point).
