INTRODUCTION

Urbanisation has been the most prominent global trend of the last decade. It is expected that 40% of India population will be urban by 2030, as against 30% currently. This is going to create a huge demand for infrastructure including housing. The shortage of urban housing stood at 18.8 million units in 2012 and is expected to grow with a CAGR of 6.6% to 34.1 million units by 2022. The Government of India has taken several steps to address this demand, one among many being the Housing for All' or Pradhan Mantri Awas Yojana (PMAY) scheme which aims to bring pukka house to every family in urban cities by 2022.

In line with its philosophy and with the purpose of taking sustainability to the masses, GRIHA has developed a new rating variant called as "GRIHA for Affordable Housing" which is aligned to the PMAY. With the help of GRIHA AH rating, many low-income households shall be able to reduce the operational costs and GHG emissions by improving their resource efficiency. The rating would evaluate the environmental performance of residences holistically over its entire life cycle. The rating thus provides a definitive standard for what constitutes a 'green building' as it is a dedicated assessment cum rating tool, and a pre-fed calculator based system.

CRITERIA AND THEIR WEIGHTAGE:

GRIHA for Affordable Housing rating is a performance-oriented system where points are awarded for meeting the intent (appraisals) of the criteria. Each criterion has certain number of points assigned. Compliances, as specified in the relevant criterion, have to be submitted in the prescribed format. While the intent for some of the criteria is self-validating in nature, there are other criteria such as facilities for construction workers, environmental awareness, energy and water metering, etc. which need to be validated on-site through due diligence visit conducted by GRIHA Council during construction. The points related to these criteria (specified under the relevant sections) are awarded after verification through monitoring, validation, and submitted documents/photographs to demonstrate compliance. GRIHA Affordable Housing rating system is a 100 point system consisting of 30 criteria categorized under six sections such as, Site Planning, Energy & Occupant Comfort, Water Savings, Waste Management, Sustainable Building Materials, and Social Aspects. Out of these 30 criteria, four are mandatory and eight are partly mandatory, while the rest are optional. Each criterion except for the mandatory criteria; has points assigned to it. It means that a project intending to meet the criterion would qualify for the points. Different levels of certification (one star to five stars) are awarded based on the number of points earned. The minimum points required for certification is 25.
