Foreword

We all are aware that the resources we inherit from Mother Earth are limited. If we are to ensure their availability to future generations, we have to use them wisely.

The rapid urbanization and development of infrastructure is an inevitable and irreversible process. We have learnt now; that development can happen with the environment instead of against it.

Going green is going close to nature. Resources like sunlight, natural wind, and water, are essential for human hygiene. Science has revealed many secrets of nature. We understand natural forces like never before, and

know how to make use of them for a greener environment.

Government of India offers promotions and incentives for green buildings. We are proud that the proactive actions taken by multiple agencies providing guidance, and ratings, have started bearing fruits. Many green projects have been registered over past few years and their numbers are increasing every year. While the Government is active in this area, an initiative from an industrial association was missing.

I am happy to note that initiative taken by CREDAI Pune Metro to bring out this Green Building Manual is appreciable. The said manual goes beyond the level of awareness and provides the developers essential data, costing, and a rich collection of resources to get started with a Green Building project of their own.

I congratulate CREDAI Pune Metro for this initiative and hope that it will seed the tree of Green Buildings all over India very soon.

Preface

Dear Members,

In the past decade, real estate industry has experienced huge growth and development activity. Multiple medium and large scale building construction projects have come up to provide various types of housing needs. It is important that development activity is sustainable and hence, as a part of our mission at CREDAI Pune Metro, we have pledged to ensure sustainable development.

In order to promote sustainable development and to create awareness

on various aspects pertaining to Cost, Benefits, Laws, Certification, a dedicated team at CREDAI Pune Metro has come up with “Real Estate Developer’s Green Building Manual”. The manual explains how you can start working on the green building project right from site selection and architecture to environment-friendly materials and process. The manual talks about types of green ratings, application process, and the green rating success strategy. It is rich with reference information, including the documents and photographs needed.

In order to promote sustainability, and to protect our Mother Earth, let us all pledge to ensure that by year 2025 all buildings constructed in India would be Green Buildings.

I thank Pune Metro members for their valuable contribution to this manual.

The Green Revolution has already begun. Come join hands and let’s make a greener tomorrow.

Mr. Shantilal Kataria

President

1 What is a Green Building

1.1 Conventional Definition

A green building (also known as green construction or sustainable building) is designed and constructed such that it makes optimum use of natural resources and minimizes the overall negative environmental impact during its life-cycle.

With increasing concerns for growing environmental problems, the need to 'Go Green' is felt in the world at large. Developers too, are making an effort to contribute towards this 'Go Green' movement in their own way through their own work. They are bringing about this by constructing green buildings.

A green building design finds the balance between construction and environment. This practice expands and complements the classical building design concerns of economy, utility, durability and comfort. Thus, a green building is also known as a sustainable or high-performance building.

An ideal green building preserves most of the natural environment around the project site and yet serves its purpose. The construction and operation promotes a healthy environment by not disturbing the land, water, energy, and resources in and around the building.

2

1.2 Five Key Benefits

The main focus areas of a green building are Energy, Water, Sites, Materials, and Indoor Air Quality. We take a holistic perspective while working on them to conserve the environment.

Focus Areas of Green Building

There are great environmental, economic, as well as social benefits obtained from the construction of a green building.

1. The resource efficiency provided by green building shows a reduction in operational costs (especially at higher occupancy level), which redeems any additional project costs and continues to offer substantial long-term savings.

2. A green building needs less local power grid and water supply; therefore, there is lesser dependency on civic infrastructure.

3. A green building incorporates various environment-friendly techniques like renewable energy, enhanced daylight.

4. A green building design substantially reduces wastage of water by installing low-flow fixtures such as aerators; a flow sensor, dual flushing systems etc., and by recycling grey-water for flushing and landscaping, it further optimises the use of water. Further, by rain water harvesting, potable water can be used to recharge the ground aquifers so as to increase the water table.

3

5. A green building emphasizes natural ventilation so as to reduce dependency on artificial methods of cooling. Further, by using low embodied energy materials during construction, improves the quality of living and ensures healthy as well as comfortable living and work environment.

1.3 Principles of Green Buildings

When we discuss environmental conservation, we must consider the Four R’s of environment preservation. These are - Reduce, Recycle, Recharge, and Reuse. These four principles form the cornerstone of sustainable development.

Green Principle

Reduce

We know that natural resources are depleting so rapidly that unless we replenish them, soon there will be nothing left. Reduction means you use less, consume only as much is required, and produce less waste.

An example of this is the usage of Drip Irrigation. The use of water for plants can be significantly brought down by using Drip Irrigation instead of manually watering plants using tubes or buckets. Drip Irrigation also gives enough time to the plants for absorbing water, making them flourish.

Reuse Reduce

Recharge Recycle

2 Myths & FAQs

2.1 Myths

Myth: Green Building is capital-intensive and time-consuming.

Fact: When planned properly, a Green Building is neither capital intensive nor time-consuming. However, it does involve an initial additional investment of around 4%-7% of the construction cost. It can be recovered in the form of incentives and benefits.

Myth: I need to make significant changes to my organization to make a Green Building.

Fact: All green-certified developers can tell you that the organization structure need not change. Planning a green building will bring in clarity of thought and discipline to your team. This, in turn, will improve productivity and operational efficiency.

Myth: Customers are not willing to pay more for Green Buildings.

Fact: Based on customer interaction it is observed that customers are in fact more aware of the importance of Green Buildings. In fact, they are willing to pay a premium price. They see value for their children in a Green Building environment. They believe that practices like water recycling, waste segregation, and so on, make their children aware and form good habits. Further, they also realise that in current times of severe drought and power shortages, green buildings offer a sustainable solution.

Myth: The maintenance cost of green building (post-delivery) is very high.

Fact: The maintenance cost of a Green Building is inversely proportional to its occupancy level. All the infrastructure is designed for full occupancy. During the initial years, occupancy is a little less, therefore the cost may seem high. But, when the occupancy goes above 70%, the maintenance cost goes down.

For example, the cost of water tanker is Rs. 900/- per 10,000 Litres. However, if you use treated (recycled) water, this cost comes down to Rs. 300/- per 10,000 Litres. As the plants are used to their full capacity, the cost advantage goes on increasing.

2.2 FAQs

2.2.1 Cost-related

What is the percentage cost difference between a Green and a Non-green Building?

Answer: For a 3-star/Silver-rated Green Building and a Non-green Building, the difference in the construction cost is about Rs. 100/- per sq. ft. (approximately 2% to 5%)

What is the additional premium per square foot that I can get to my selling price?

Answer: The additional cost per square foot cannot be quantified. However, it will help you in attaining a better sales velocity and creating a brand differentiator in the current competitive environment.

What is the benefit to occupants?

Answer: Savings of 10-15% in Property tax (throughout the life of the building), better amenities, and better standard of living are the prominent benefits.

There is also reduction in energy bills for the entire life cycle of the project.

As an example: For a developer working in Pune, as per Pune Municipal Corporation (PMC) and Pimpri-Chinchwad Municipal Corporation (PCMC) rules; there is a rebate of 10 to 15% of development charges and premiums. This is converted to approximately to Rs. 30/- per sq. ft.

Note that these numbers can change according to the civic body rules in your city/town.

How does a Green Building compliment a smart city?

Answer: All principles of a smart city, such as Sewage Treatment, Rain Water Harvesting, and Solid Waste Management, are incorporated in the rating points of a Green Building. Therefore, a green building complements a smart city.
