As sustainability takes center stage in modern construction, how we design and build our spaces is undergoing a major conversion. Today, understanding the difference between green and normal buildings can have a long-term impact on the environment, energy consumption, and overall efficiency. 

While conventional buildings focus on functionality and cost, green buildings prioritise resource optimisation, eco-friendly materials, and reduced carbon footprint. 

In this blog, we’ll explore the key distinctions between green and conventional buildings, helping you understand why sustainable construction is necessary for the future.

What is a Green Building?

Green buildings, also known as sustainable or eco-friendly buildings, are designed to minimise their environmental impact throughout their lifecycle, from planning and design to construction, operation, and even demolition. These buildings aim to efficiently use energy, water, and materials while promoting a healthier living and working environment.

Green buildings are constructed with sustainability at their core, focusing on reducing pollution, conserving natural resources, and enhancing the well-being of occupants.

Key Features of Green Buildings

• Energy Efficiency: Designed to use less energy through efficient lighting, HVAC systems, insulation, and often renewable energy sources like solar or wind power.

• Water Conservation: Incorporates low-flow fixtures, rainwater harvesting systems, and wastewater recycling to reduce overall water usage.

• Sustainable Building Materials: Utilises recycled, renewable, or locally sourced materials with a lower environmental impact.

• Improved Indoor Air Quality: Non-toxic paints, adhesives, and ventilation systems ensure healthier indoor environments.

• Efficient Waste Management: Encourages waste reduction during construction and promotes recycling and reuse of materials.

• Smart Design and Layout: Through thoughtful architecture, it maximises natural light and airflow, reducing dependence on artificial lighting and ventilation.

• Environmental Certification Compliance: Meets criteria set by recognised green building rating systems like LEED (Leadership in Energy and Environmental Design), GRIHA, or BREEAM.

• Reduced Carbon Footprint: Emphasises practices and technologies that significantly cut greenhouse gas emissions over the building's lifetime.

Unlike traditional structures, which often prioritise cost and functionality over sustainability, green buildings are carefully planned to minimise environmental impact and promote long-term efficiency. 

This focus influences everything from selecting materials and site planning to energy systems and waste management practices. As a result, green buildings differ significantly from conventional buildings. Let’s explore these key differences in greater detail!

Green vs. Conventional Buildings: A Detailed Comparison

Green and conventional buildings serve the same fundamental purpose of providing shelter and functional spaces; their design philosophies, construction practices, and long-term impacts on the environment and human health vary significantly. Let’s explore how green buildings stand out from their traditional counterparts.

Let’s examine these significant differences in greater depth.

1. Core Philosophy and Purpose

Green buildings are designed with sustainability at their core. Their main goal is to minimise environmental impact, conserve natural resources, and enhance occupant well-being. From the early design phase to eventual demolition, green buildings aim for low carbon footprints and energy efficiency.

On the other hand, conventional buildings are constructed primarily with the focus on immediate cost-efficiency and functionality. Environmental considerations are often secondary or overlooked. These buildings typically follow traditional architectural models without integrating sustainable principles.

2. Materials Used

Green buildings utilise eco-friendly, non-toxic, and often recycled materials. Examples include bamboo flooring, recycled steel, low-VOC paints, and sustainably sourced wood. These choices reduce the strain on natural resources and improve indoor air quality.

In contrast, conventional buildings commonly use standard construction materials such as concrete, bricks, steel, and synthetic paints, which may be cheaper upfront but often involve higher carbon emissions during production and potential health risks due to chemicals used.

3. Energy Efficiency

Energy consumption is one of the most striking differences. Green buildings incorporate energy-saving technologies such as solar panels, energy-efficient HVAC systems, LED lighting, and intelligent energy monitoring. These systems reduce reliance on non-renewable energy sources and lead to long-term cost savings.

Conventional buildings typically rely on traditional power sources and less efficient systems. As a result, they tend to consume more energy over time, leading to higher utility bills and a greater environmental burden.

Example: The CII-Sohrabji Godrej Green Business Centre in Hyderabad is a LEED Platinum-rated green building that saves up to 45-50% energy compared to conventional counterparts.

4. Water Management

Water conservation is a significant focus in green buildings. Features like rainwater harvesting, greywater recycling, water-efficient fixtures, and native landscaping help minimise water usage and manage resources wisely.

Conventional buildings generally lack such integrated water systems, often resulting in higher water consumption and wastage, especially in urban settings where water is already scarce.

5. Waste Management

Green buildings emphasise reduced construction waste, promote on-site waste segregation, and integrate composting or recycling mechanisms. Materials are carefully selected and managed during construction and operation to avoid excess waste.

In conventional buildings, construction and operational waste are rarely minimised or recycled efficiently, contributing to larger landfill burdens and environmental pollution.

6. Indoor Environmental Quality

One of the most human-centred advantages of green buildings is their focus on indoor air quality, thermal comfort, and natural light. They are designed to maximise daylight, improve ventilation, and minimise the use of harmful chemicals, leading to better health and productivity for occupants.

Conventional buildings often overlook these aspects, relying heavily on artificial lighting and ventilation, resulting in poor air quality, higher stress levels, and lower workplace satisfaction.

7. Long-Term Cost and Maintenance

Although green buildings may involve higher initial costs due to advanced technology and specialised materials, they result in significant long-term savings through reduced energy, water, and maintenance bills. They also tend to have higher resale value and qualify for green certifications, which can attract conscious buyers or tenants.

Conventional buildings are less expensive upfront, but incur higher operating and maintenance costs over time, especially with rising energy prices and potential penalties for not meeting environmental regulations.

8. Regulatory Compliance and Certifications

Green buildings often aim for certifications such as LEED (Leadership in Energy and Environmental Design), IGBC (Indian Green Building Council), or GRIHA (Green Rating for Integrated Habitat Assessment). These certifications validate the building’s sustainability standards and are increasingly valued by investors and stakeholders.

Conventional buildings may not seek or qualify for these certifications, and as green regulations tighten worldwide, they may face challenges in staying compliant in the future.

9. Environmental Impact

Ultimately, green buildings are a proactive solution to environmental challenges. They reduce carbon emissions, conserve biodiversity, and create healthier communities. Conventional buildings, by contrast, contribute significantly to global greenhouse gas emissions, urban heat islands, and resource depletion.

Example: According to the World Green Building Council, buildings are responsible for nearly 39% of global carbon emissions, making green construction a vital part of climate action.

10. Innovation and Technology Integration

Green buildings are at the forefront of smart and sustainable technology integration. They make use of IoT-enabled systems, automated energy controls, green roofs, building management systems (BMS), and even AI-based optimization for lighting, heating, and cooling. These innovations not only improve efficiency but also offer real-time data to monitor and reduce environmental impact.

In contrast, conventional buildings generally lag in technological adoption. They often depend on manual controls and outdated systems that offer limited adaptability and optimization. This results in reduced operational efficiency and higher long-term energy costs.

Example: The Infosys SDB 1 building in Mysuru is a powerful case study in smart green infrastructure. It uses radiant cooling technology with a 24x7 automated building management system, leading to a 50-60% reduction in energy consumption for air-conditioning compared to conventional systems. 

While the advantages of green buildings over conventional structures are evident, widespread adoption still faces several roadblocks. Let’s cover it in our next section!

• Even though these costs are offset over time through energy and maintenance savings, many developers and clients focus on short-term budgets.

2. Lack of Awareness

• Many property owners, builders, and even policymakers are still unaware of the long-term benefits of green building practices.

• Misconceptions persist that green buildings are only for high-end or luxury projects.

3. Limited Availability of Green Materials & Technology

• In some regions, it’s challenging to source eco-friendly materials, energy-efficient appliances, or skilled labour familiar with sustainable construction techniques.

• Importing such materials can further drive up costs and timelines.

4. Regulatory Gaps

• Not all countries or cities have strong policies or incentives promoting green construction.

• Where regulations exist, they may not be enforced effectively, reducing motivation for developers to adopt eco-friendly practices.

5. Resistance to Change

• Traditional building practices are well-established, cost-effective, and backed by decades of experience.

• Many contractors and architects hesitate to adopt new approaches due to unfamiliarity or perceived risk.

6. Certification Challenges

• Obtaining certifications (like LEED, BREEAM, or GRIHA) involves documentation, third-party assessments, and time-consuming processes.

• Smaller developers may avoid these complexities altogether.
