only the health and freedom of our species, but access to the world in which the human spirit was

born.”“The Diversity of Life”

SCENARIO

NICMAR,PUNE

Today, green building is one of the fastest growing building and design concepts. Every month new magazines are popping up that report on this growing trend.

Architects, designers, and homeowners are becoming aware with the cost saving possibilities, energy saving emphasis, modern look, and the symbiotic relationship with nature that green buildings possess.

PROMOTIONAL PROJECTS :• Green Campus Day• Brochure• Posters and signs• Recycling centers• Environmental education• Awareness campaign• Green concept fostering competition• Festivals & Exhibitions.

PERCEPTION & REALITIES

NICMAR,PUNE

PERCEPTION REALITYPerception 1: Green buildings are costlier

The incremental cost would appear small if the baseline design is already at a certain level of good eco-design; it would appear huge if the base design has not considered green principles.

Perception 2: Green buildings have to be air-conditioned

Green building concepts and the LEED rating can be applied for non-air conditioning buildings. It has been applied on three such buildings in India viz., IGP office, Gulbarga and Hyderabad Institute of Technology and Management.for example – the envelop, lighting, roof insulation etc.

Perception 3: Green buildings take more time

Due to the Green building movement; now there is so much of capacity building that has happened in the country.

CLIMATE RESPONSIVE APPROACH

NICMAR,PUNE

In India we have a diverse and rich tradition in ‘Building Design’. In the Indian context, climatologically aspects have always been at the core of building design.

Pune region, with temperatures touching 40 deg cel, it is predominantly a hot climate. The traditional ‘Vaada’ has thick walls that prevent heat penetration. The use of stones, with a high thermal mass, in construction further helps to keep away the heat.

The plans of the old buildings are inward looking ,almost entirely block the hot air coming from outside.

Provision of cooling effect inside the house.

Today :

The target audience for green buildings is mostly the corporate sector. As we take up large scale, complex projects the list of requirements in utilities like air conditioners, elevators, pumping systems etc. is expanding rapidly.   The result is Energy Intensive buildings.

TODAYS APPROACH

NICMAR,PUNE

The United States Green Build Council (USGBC) is the foremost leader. They are the sanctioning body for LEED, the program with which points are awarded to various design applications within a building ultimately resulting in LEED certification for the building.

Whereas in India foremost leader in green building is Indian green building council (IGBC) and followed by GRIHA by TERI. The sanctioning body is LEED-INDIA. 

Use of other standards like NBC,ECBC,BEE,ASHARE while implementing.

WHAT TO DO?

NICMAR,PUNE

Objective

Scope & Limitation

To recommend for preparation of an application guide for green structure in tropical climate, which shall impart awareness and understanding of green buildings to every user in the most simplified manner. To attain this objective comparative studies of different green buildings have been done in the region of Pune & other regions of tropical climate.

Green building and sustainability in construction itself is a vast topic. Instead of giving examples and study of various green buildings, we are providing a reference guide for the construction of green building with respect to tropical climate which shall foster the knowledge about green building construction even to commoner.

SOLUTION

NICMAR,PUNE

Define application guide and use

The purpose of this guidance document is to provide direction when applying green building elements during construction.

Commercial development and various projects represent a great opportunity for sustainable planning and design.

We recognize that this market requires unique guidance in order to implement the sustainable structure with the help of availability of material and techniques. It also help to reach to the manufacturer of the product by the users.

Sustainable sites

SS2 Site development For physically

challenged

Development and construction processes are often destructive to local ecology. Fortunately, steps can be taken to reduce impacts on previously undeveloped lands and to improve site.

Almost any building can be made accessible to physically challenged ,so that ingress and egress to buildings by physically challenged maybe facilitated while preserving the desired design and effect of the architecture.

Water Efficiency

NICMAR,PUNE

Freshwater becomes increasingly scarcer due to urbanisation and available sources being rendered polluted and unsuitable for human consumption. Conservation of water, thus, is an inevitable recourse for sustenance of human life.

Power Flowers is the latest iteration of advanced wind power generation. These wind trees need less space. Less land intensive than even a pole-mounted residential horizontal axis wind turbine

Energy consumption can be dramatically reduced through practices that are economical and readily achievable. improving the energy performance of buildings lowers operation cost, reduces pollution generated by power plants and other energy producing equipment and enhances comfort.Most energy efficiency measures present and excellent rate of return

NICMAR,PUNE

Building material choices are important in sustainable design because of the extensive network of extraction, processing and transportation steps required to process them. Activities to create building materials pollute the air and water, destroy natural habitats and deplete natural resources.

Compressed Earth Block (CEB) The Auroville Building Centre has designed a press for CEBs, which is manufactured by Aureka, and sold in India, Africa and even Europe.In Auroville, the average results obtained with CEB at 5% cement are (±) 50 kg/cm2 .Local fired country bricks are at (±) 35kg/cm².

Ferrocement is a form of reinforced concrete using closely spaced multiple layers of mesh and/or small diameter rods completely infiltrated with, or encapsulated in, mortar. The most common type of reinforcement is steel mesh.Other materials such as selected organic, natural or synthetic fibres may be combined with metallic mesh.

CONCLUSION

NICMAR,PUNE

Synthesizing possibilities for building materials in the key areas of production, consumption, recycling, evaluation and regulation which might be of interest to those more generally concerned with either social change or ‘information age’ economic development strategy.

This enabled us to make an application guide comprising of the most efficient techniques which could be implemented while constructing any other green projects in future and in the same geographical context, which will be helpful to every individual who desires to construct the energy efficient structure.

NEED OF TIME…

resources is just as important as defense abroad. – Robert Redford.
