Energy Efficient Energy Efficient Solar/ Green Buildings Solar/ Green Buildings
• Designed to provide internal comfort with much less consumption of conventional fuel; results in savings of recurring and capital costs
• Design depends on direction & intensity of sun & wind, ambient temperature, humidity etc. Different designs for different climatic zones.
• Key features: Orientation, double glazed windows, window overhangs, thermal storage walls/ roof, roof painting, ventilation, evaporation, day lighting, construction material etc.
• Active solar thermal and photovoltaic systems can also be incorporated.
• Additional cost could be up to 10% with annual savings of energy up to 30 to 40%.

Programmes of the MinistryProgrammes of the MinistryThe Ministry has been promoting solar passive
buildings in the country for more than two decades through◦ Research and development activities◦ Demonstration of solar passive buildings◦ Supporting workshops, training programmes, orientation
courses, etc.◦ Supporting to bring out technical literature
Initial efforts (during mid-eighties) led to construction of solar passive buildings in three climatic zones of the country viz. Houses at IIT Delhi (Composite), Hostel at Jodhpur (Hot and dry), and Extension of a dispensary at Srinagar (Cold and cloudy).
Developments under Ministry’s Developments under Ministry’s R&D ProjectsR&D Projects
Development of tools for architecture design and simulation (TADSIM) for solar passive buildings (IIT Bombay).
A study on Energy Efficient Buildings in India (TERI)
A manual of Solar Passive Architecture (SEC and IIT Bombay)
Development of the course material on Solar Passive Architecture for inclusion in the curricula of Bachelor of Architecture (Council of Architects and IIT Delhi)
Developments under Ministry’s Developments under Ministry’s ProjectsProjects
Production of a set of two CDs entitled “Knowledge Bank for Sustainable Buildings” and “Energy Efficient Buildings in India” (TERI)
Handbook on Energy Conscious Buildings (SEC and IIT Bombay)
Assessment study for energy supply of solar passive designed buildings in Himachal Pradesh (SEC and HPSCST&E)
National Rating System for National Rating System for Green BuildingsGreen Buildings
Building rating systems becoming popular for promotion of green buildings. In India, US based LEED in operation.
A National Rating System - GRIHA developed in association with TERI
Applicable to AC/ non-AC & intermittent cooled buildings & suitable for different zones of the country
Developed & modified through interactions with all stakeholders. Compatible with NBC 2005 & ECBC 2007
System to help in assessing predicted performance of buildings over their entire life cycle
Operates on 100 point marking system. 43 points pertain to energy & waste management.
National Rating System for National Rating System for Green BuildingsGreen Buildings
Buildings to be star rated based on evaluation during pre-construction, building design and construction, and building O&M stages.
Points scored Rating50–60 One star61-70 Two star71-80 Three star81-90 Four star91-100 Five star
The main aim of the programme is promotion of solar/ green buildings
It is a dynamic system taking cognizance of various feed backs from live projects through◦ Technical Advisory Committee, which is formed to
provide technical guidance on updation of GRIHA◦ National Advisory Council, formed to advice and give
directions to the National Rating System System is incentivized by the MinistryCommercial and institutional buildings including
housing complexes with minimum built area of 2500 sq. m. are covered
5 million sq. m. of built area targeted during 11th Plan

Reduced energy consumption without sacrificing the comfort levels
Reduced destruction of natural areas, habitats, biodiversity & reduced soil loss from erosion
Reduced air & water pollution with direct health benefits
Reduced water consumptionLimited waste generation due to recycling and reuseIncreased productivity, enhanced image &
marketabilityProjects need to be registered with GRIHA
Secretariat.
Seed funding for GRIHA Secretariat90% of the fee for projects rated 3-star having
built up area up to 5000 sq. m. and for projects rated 4 star having built up area above 5000 sq. m. to be reimbursed by MNRE
