HOME- What would you prefer ?

A concrete jungle OR A greener one…. ?

Healthy Way….• We have been aware of the need to live in places that promote a healthy

way of life and therefore the well-being of people.• India’s antique heritage buildings have fully demonstrated how such

buildings were regarded and made.• With the advent of Industrialization there was an increase in pollution

and Global warming.• It lead to Environmental degradation on a large scale. Protection of our

eco system became the need of the hour.

This lead to the birth and need of Green Building concept!

Key Questions

1. Why “Green” Building?2. What is the difference between

“Green Building” and “Conventional Building”?

3. What benefits do we get by going “Green”?

Defining Green Buildings“Design and construction practices that significantly reduce, or eliminate the negative impact of buildings on the environment and its occupants with regard to site planning; safeguarding water use and water use efficiency; promoting energy efficiency and renewable energy; conserving materials and resources; and promoting indoor environmental quality.” (US Green Building Council)

What does Green Building Offer?

• Indoor Air Quality (IAQ) is one of the top 5 factor which cause environmental risks to public health. People spend 90% of their time indoors.• Indoor contamination levels can be 25 times

as high as outdoors.• Inadequate ventilation can further result in

biological contaminants.

Solutions: Eliminates sources of contaminated air and increases ventilation and fresh air to occupants.

Water Efficiency

· Water savings from:8Water-efficient fixtures and appliances8Water-efficient landscaping8Rainwater collection systems8Grey water reuse

· Benefits include:8 water bills8 volumes of wastewater8 energy costs for hot water

Employee Productivity

· Green buildings worker productivity

· Environmental factors impacting productivity

Indoor air qualityClimate controlLighting, esp. day lighting“Biophilic” features - Views, plants, etc.

Material Efficiency

Efficient use of building materials & land.

Environmental benefits· Saves “embodied” energy· Saves energy & water over life of

building· Use of non-virgin or recycled materials

8 Depletion of natural resources8 Mining & manufacturing pollution8 Durable materials last longer, costs

Energy Conservation

• Energy usage depends on the local climate, density of occupancy, occupancy schedule, orientation of the building and internal loads.• Proper design engineering and

planning would lead to energy savings.• Solar energy and Wind energy are

methods of improving the building into a greener one.

Green Building Rating Systems

It is the collective effort of Architects, Project Management Consultants, Building Design Consultants, MEP Engineers and Civil Engineers to design & construct a Green wonder.There are many organizations and their rating systems which help in achieving your dream towards a green project.

Let us now address the questions we raised…

1) Why “Green” Building?

Purpose:• To enhance a building’s overall performance while

improving comfort; indoor air; energy, water and materials efficiency.

• Energy savings in Green Buildings could range from 20 to 30 % and water savings from 30 to 50 % which considerably reduces cost.

• A green building may cost 5 to 10 % more to design & build than a regular building; but these cost can be recovered in just 2 years in power and water savings.

2) What is the difference between “Green Building” and “Conventional Building”?

• External Appearance: Both look alike• Functionality: Both are same

Differences:

1) Conserve natural resources2) Concern for human comfort, Indoor environment & productivity.

Difference Between Green & TraditionalAppearance of Green Buildings

• You design it to look how you want.• Carpet, furniture and windows do not have to look

different. They can look like traditional ones only they perform better and are healthier.

• Does not need to be high tech to be green.Time

• Green Buildings take the same amount of time to construct as regular buildings. More time may be required in the Design phase though.

Costs• Green Buildings do not have to cost more. With

planning they can be built at the same price or less.• Design fees may be higher in the beginning of the

project but the extra design work will lower the actual construction costs. In the end the building costs the same and fits in the traditional budget.

Sustainable Development

1) Environmental benefits: • Enhance and protect ecosystems and biodiversity.• Improve air and water quality.• Reduce solid waste.• Conserve natural resources.

2) Economic benefits: • Reduce operating costs.• Enhance asset value and profits.• Improve employee productivity and satisfaction.• Optimize life-cycle economic performance.

3) Health and community benefits: • Improve air, thermal, and acoustic environments.• Enhance occupant comfort and health.• Minimize strain on local infrastructure.• Contribute to overall quality of life.

3) What benefits do we get by going “Green”?

India’s Stand On Green Building• According to the USGBC rating system LEED

(Leadership in Energy and Environment Design); India ranks 3rd globally with 1657 LEED certified and registered projects as of April, 2014.• Indian Green Building Council (IGBC) has a

vision to usher in a green building revolution in India and to become one of the world leaders in green buildings by the end of 2015.• Through Green Build; India represents not

only growing benefits for human health and operational cost savings but also its potential to be part of the solution to a warming planet and rising sea levels.
