A green building is a structure designed, constructed, and operated to minimize its environmental impact and create a healthy, sustainable space. The concept of green building, also known as sustainable building or eco-friendly building, emphasizes the efficient use of resources like energy, water, and materials, as well as the reduction of pollution and waste throughout the building’s life cycle.

Key Features of a Green Building:

1. Energy Efficiency:
   • Green buildings are designed to use less energy by incorporating energy-efficient technologies such as:
     • Insulation: Proper insulation of walls, roofs, and windows helps maintain temperature, reducing heating and cooling energy consumption.
     • Solar Panels: Photovoltaic panels can generate electricity from solar energy, reducing reliance on non-renewable sources.
     • LED Lighting: Energy-efficient lighting systems reduce electricity use.
     • Energy-efficient HVAC systems: Heating, ventilation, and air-conditioning systems are optimized for minimal energy usage.
2. Water Efficiency:
   • Green buildings incorporate systems to reduce water consumption and recycle water, including:
     • Low-flow fixtures: Such as faucets, showers, and toilets to minimize water use.
     • Rainwater harvesting: Collecting and storing rainwater for irrigation or non-potable uses like flushing toilets.
     • Greywater recycling: Reusing water from sinks, showers, and laundry for landscape irrigation.
3. Sustainable Materials:
   • Use of sustainable, renewable, and locally sourced materials is a key element in green building:
     • Recycled or Reclaimed Materials: Utilizing recycled steel, wood, or glass reduces the demand for raw materials.
     • Low VOC Materials: Using paints, adhesives, and materials with low volatile organic compounds (VOCs) ensures healthier indoor air quality.
     • Bamboo and Cork: These are sustainable alternatives to traditional wood because they regenerate quickly.
4. Waste Reduction:
   • During construction, waste reduction is achieved by:
     • Recycling Construction Waste: Reusing or recycling materials from the construction process.
     • Modular Construction: Prefabricated materials can be assembled with less waste and more precision.
5. Improved Indoor Air Quality:
   • Green buildings are designed to enhance air quality by:
     • Natural Ventilation: Designing spaces to allow air to flow naturally reduces the need for mechanical ventilation.
     • Air Filtration: Advanced HVAC systems with air filters help maintain cleaner indoor air.
     • Non-toxic Materials: Use of non-toxic finishes, adhesives, and furnishings to limit indoor air pollution.
6. Sustainable Site Development:
   • Site selection and development are crucial to minimizing the environmental impact:
     • Minimizing Land Disturbance: Building on previously developed land or using designs that reduce the impact on ecosystems.
     • Native Landscaping: Using plants that are native to the area reduces the need for irrigation and chemical fertilizers.
     • Urban Planning: Locating buildings near public transportation and amenities reduces the need for car travel.
7. Renewable Energy:
   • On-site renewable energy systems, such as solar, wind, or geothermal energy, help green buildings generate part of their own energy needs and reduce dependence on fossil fuels.
8. Waste Management:
   • Green buildings aim to minimize waste generation through:
     • Composting: Organic waste can be composted instead of sent to landfills.
     • Recycling Stations: Providing accessible recycling bins for occupants encourages proper waste segregation.
9. Stormwater Management:
   • Green roofs: Vegetative roofs help absorb rainwater, reduce heat absorption, and create green space.
   • Permeable Paving: Permeable surfaces allow rainwater to infiltrate into the ground, reducing runoff and helping with groundwater recharge.
10. Adaptability and Resilience:
    • Green buildings are designed to adapt to changing conditions, making them resilient to future environmental challenges. This includes designing buildings to withstand extreme weather conditions or changing energy requirements.

Benefits of Green Building:

1. Environmental Benefits:
   • Reduces carbon footprint.
   • Minimizes waste and conserves natural resources.
   • Improves air and water quality.
   • Helps reduce urban heat islands through green roofs and landscaping.
2. Economic Benefits:
   • Energy-efficient designs lead to lower utility bills.
   • Green buildings have higher property values and occupancy rates.
   • Incentives like tax credits or grants may be available for eco-friendly construction.
3. Health Benefits:
   • Improved indoor air quality promotes the health and well-being of occupants.
   • Use of non-toxic materials reduces the risk of respiratory issues and allergies.
   • Natural lighting and ventilation improve mental and physical well-being.
4. Social Benefits:
   • Green buildings contribute to the well-being of communities by reducing environmental impact.
   • They promote sustainable living practices and inspire eco-friendly innovations.

Green Building Certifications:

Several certification programs exist to rate and encourage sustainable building practices:

• LEED (Leadership in Energy and Environmental Design): A widely recognized green building certification system that assesses a building’s environmental performance.
• BREEAM (Building Research Establishment Environmental Assessment Method): A certification standard primarily used in Europe to evaluate the sustainability of buildings.
• IGBC (Indian Green Building Council): A certification for green buildings in India.
• WELL Building Standard: Focuses on the health and wellness impacts of buildings.

Conclusion:

Green building is an approach to construction that seeks to reduce the environmental impact of buildings while improving the health, comfort, and well-being of occupants. By employing energy-efficient systems, sustainable materials, and renewable energy sources, green buildings help address some of the most pressing environmental challenges.

CHAPTER 1

INTRODUCTION

1.1 GENERAL

The objective of the project is to select for modifying the design of General construction and services to suit LEED requirements – Green Building Concept so to save maximum energy and protect our environment.

Buildings annually consume more than 20% of the electricity used in India. Development shifts land usage away from natural, biologically-diverse habitats to hardscape that is impervious and devoid of biodiversity. Green Building practices can substantially reduce or eliminate negative environmental impacts and improve existing unsustainable design, construction and operational practices. As an added benefit, Green design measures reduce operating costs, enhance building marketability, increase worker productivity and reduce potential liability resulting from indoor air quality problems.

Energy conservation and Environment protection has received attention in India since mid 70s. The Impact of the energy conservation and Green Building efforts are felt at a very low pace, as the commercial energy consumption per capita is low in the country and efficient end use devices are costly. Recent rapid increase in energy demand, mainly in the industrial and the service sectors has created a renewed awareness about the economic advantage of energy conservation.

A structural change in the economy has led to expansion of the industrial base in the country, and subsequently the increase in demand of energy. Electricity generation sector has not expanded at a desirable level. This is also supported a renewed effort on Green Building Concept.

Also, the Globalization and knowledge based economy brought multinational companies to set up their offices in India. Their back end operations are critical and vision on Environment protection, Compelled these companies to adopt Green Building Standards while construction & developing their offices. In order to improve the sustainability of office technical infrastructure, Clients are now inclined to invest in Green Building Concept.

This project report aims to identify opportunity to improve building design and implement the same through tender documents and monitoring while execution of Construction works.

LEED in India

Following the formation of IGBC in 2001, the members realized the need to have a system to define and measure Green Buildings. The IGBC set up the LEED Core Committee to focus on the LEED rating to suit the Indian context.

The LEED India Green Building Rating System evaluates the environmental performance from a whole building perspective over a building’s life cycle, providing a definitive standard for what is called a “Green Building”.

The rating system is categorized into 5 environmental categories –

• Sustainable Sites
• Water Efficiency
• Energy & Atmosphere
• Materials & Resources
• Indoor Environmental Quality

2.0 LITERATURE REVIEW

2.1 GREEN BUILDINGS, ORGANIZATIONAL SUCCESS AND OCCUPANT PRODUCTIVITY By Judith H. Heerwagen, Ph.D.

This brief overview of business perspectives on facilities conveys several lessons for green buildings:

• Green buildings are relevant to business interests across the full spectrum of concerns, from portfolio issues to enhanced quality of individual workspaces (through improved ambient conditions.)

• The potential influence of green buildings is broad, research on green buildings should address a range of outcomes rather than focusing narrowly on just a few. Outcomes of interest to organizations include workforce attraction and retention, quality of work life, work output, and customer relationships.

• Green buildings can provide both cost reduction benefits and value added benefits. The emphasis to date, however, has been on costs, rather than on benefits. The need for more data on value added benefits underscores the importance of studies that focus on these human and organizational factors.

It is also important to recognize that the benefits of green buildings are more likely to occur when the building and organization are treated as an integrated system from the start. As pointed out by Cole (1999), it is entirely possible to have a “green” building with “gray “ occupants due to lack of systems integration and lack of training on how to use the technologies in the most efficient and effective way. Gray occupants are also more likely to be found in buildings that “green” individual systems rather than the environment as a whole or in buildings which focus primarily on technology to the exclusion of building features that wield their effects through social and psychological mechanisms. And finally it is possible for “gray” organizations to exist in green buildings, thereby passing up significant opportunities for high-level benefits resulting from resource efficiency and process innovation throughout the organization.

2.2 Green buildings and gray occupants by Cole, R. (1999)

This report provides data from conversations, focus groups, and surveys with both

members of the construction industry and local governments about their perspectives

on the barriers and incentives for green building in their communities, primarily, in the

Pacifi c Northwest. Nearly 500 construction industry members and just over 300 local

governments participated in the research, providing one of the largest — and perhaps

the fi rst — studies of the aggregated voices for both the public and private sector on

factors that aff ect green building.

The author recommendations fall in to four broad categories that involve in providing

• Marketing to increase public demand for green guilding
• Policies and processes to support financial payback for developers
• Information, Demonstrations and training to encourage to adaptation of Green building
• Support for current users of Green building and LEED certification to continue their use and advocacy of Green building

2.3 Distinguishing among green businesses: growth, green, and anomie by Weinberg, A.S. (1998).

Environmental social scientists have yet to deal with the growing phenomenon of green businesses. In particular, we need to have some response to the notion that green businesses are significant enough to require a shift in public policy support for enhancing their proliferation. We cannot do this, however, unless we have a better sense of what constitutes a “green business. “ I argue that one way to do this is by dimensionalizing green businesses. One way to dimensionalize green businesses is by how they manage the anomie that arises as organizations attempt to meet ecological goals with market means. The strategies that businesses develop to deal with anomie reveal central issues about how green ideas have been embedded within the organization.

The Author aims at the following,

• Creating awareness of Green Building concepts
• Effectiveness of Green concepts
• Developing ideas on Green concepts

2.4 DESIGN, PRODUCTIVITY AND WELL-BEING: What are the Links? By

Judith H. Heerwagen, Ph.D.

The conceptual framework presented here suggests that buildings have potentially far reaching impacts on human well being and on organizational effectiveness. More research is certainly needed to verify and extend these connections. To begin, we need to shift our focus from thinking of buildings as real estate costs to thinking of buildings as an employee benefit – one that contributes significantly to health, performance, well being, organizational attachment. It is time to also look at how facilities can contribute to organizational well being. In doing so, we need to move beyond the bottom line. Management experts have identified a broad set of criteria against which an organization’s success is measured. The design profession must begin to look at buildings from this perspective and to design with these larger goals in mind. Although corporate image has always been a design goal, image has often been achieved at the expense of the workforce and of the surrounding community. Organizational success demands a more integrated approach, one that considers the building as part of a larger environment that includes not only the habitat on which the building sits, but the larger community as well.

Efficient use of community resources (water, electricity, land), pollution prevention and toxic reduction are key green design strategies that may well prove to be a vital link connecting the environment with people, organizations, and community livability

4.2 TARGET FOR GOLD RATING

It was decided post discussion with Client that is to proceed for Gold Rating and get design modified accordingly. We have informed Architects / Consultants to carry out the modification as discussed in the previous chapter of this project report.

Table – 4

LEED India Rating System and Certification Levels

As per above table, for new construction and to get Gold Rating minimum 39 Credits need to be achieved. During our design review meetings it was discussed with Architects about various points, preparing Green Building Norms (Parameter to Modify Building Designs). Accordingly, Architects has modified the design to achieve Gold Rating for the Project (Tata Communications Chennai) as mentioned below.

• Sustainable Sites (SS) 7 Points
• Water Efficiency (WE) 2 Points
• Energy & Atmosphere (EA) 12 Points
• Materials & Resources (MR) 14 Points
• Indoor Environmental Quality (EQ) 17 Points
• Innovation in Design (ID) 5 Points

Total points (Credits) can be achieved is 57 Credits i.e. more than what is exactly required for Gold Rating. However, in practical it will be difficult to modify many basic designs and site conditions as during construction, those suggested parameter won’t be possible to implement in totality. Team decided to focus on implementing the factors which can yield maximum credit with optimum cost.

4.3 INCORPARATION OF MODIFIED DESIGN IN THE TENDER

As elaborated in previous Chapters all design modification is to be incorporated in the Tender, so that building will be constructed accordingly. Hence achieving Gold Rating is mainly depends upon Implementation of works based on Green Building Concept (LEED), so incorporating modified design in tender is very much important.

Based on the Green Building Concepts, elaborative information were captured in the General Condition of Contract to explain contractors and contracts conditions are made to accept the norms of Green Concept.

Important site implementation points are

1. Erosion and Sedimentation Control details have been incorporated in the Tender General Condition of Contract, so that Contractor can implement those points during the construction.

2. Sustainable sites – Very luckily present construction land and locations is in primary location of city, hence approach to site, transportation from site to other parts of the city and level of land is matching with Green building norms.

3. Water Efficient Landscaping – as per Green Building requirement and discussed in the Design modification, necessary drawings has been incorporated in the tender to construct Sewage Treatment Plant, Rain water storage sumps, system to take recycled water from Sewage treatment plant to Landscape areas, Air-conditioning water reuse system by constructing Hot / Cold chilled waters storage tanks – so that portable water usage can be minimized.

4. Energy & Atmosphere – All HVAC Design and drawings have been made as per ASHRAE / ECBC and same has been recommended by Green Building norms. In the Air-conditioning system, use of less content CFC refrigerant is proposed, to reduce damage to Ozone layer.

5. Materials & Resources – In the General Condition of Contract, it has been clearly indicated that construction debris, waste need to stacked at designated place and how to re-use construction waste i.e. debris to use for filling so that these wastes will not be dumped at any outside land and damage the Environmental, Use of regional materials i.e. as per Green Buildings norms all major materials like Construction steel, Cement, Brick or Block are to be procured from local or maximum within 800KMs, recycling construction scraps i.e. steel scraps are to be given back to Steel manufacturing plants so that recycled steel can manufactured.

6. Indoor Environmental Quality – As per Green Building norms, the ASHRAE / ECBC standards are followed to maintain the indoor air quality. In the layout drawing, Air-conditioning for Cafeteria and Office space has been separated to minimize growth of micro organism in the Indoor air, prohibiting smoking in the building or having isolated smoking zone in the campus to control quality of air, ensured fresh air intake locations for AHUs are away from Toilet Exhaust points.

7. Innovation & Design Process – It was agreed to have better strategies to review design continuously while in tendering and construction stage, so to increase the Green Building Credit points and also implement better design even if it not specified in the Green Building norms.
