The global wave of urbanization has profoundly reshaped landscapes, impacting natural resources and intensifying carbon emissions. According to the UN, a staggering 55% of the world’s population currently resides in urban areas, a figure projected to surge to 68% by 2050. This projected figure signifies a future where two-thirds of humanity will call cities their home.
Examining Bengaluru’s swift urbanization, we see it ranked third among India’s most populous cities with 13,608,000 residents, marking a 3.15% increase from the previous year. Known as India’s Silicon Valley, Bengaluru attracts IT firms, startups, and global corporations. Oxford Economics anticipates it as the Asia-Pacific region’s fastest-growing city in 2023. This emphasizes the need for sustainable choices in our development projects.
However, this rapid growth presents challenges. The city’s infrastructure struggles with the rising population, causing traffic congestion, insufficient public transport, and urban discomfort. Moreover, as urban expansion outpaces infrastructure development, pressing environmental concerns like disappearing green spaces, pollution, and water scarcity have emerged.
In the real estate sector, many organizations are addressing the downsides of unchecked urbanization. Sustainable and energy-efficient building practices are gaining prominence, leading to various building styles like green buildings, traditional structures, and energy-efficient designs. This blog aims to comprehensively compare these three building types, highlighting their unique traits, benefits, and challenges.
In simple terms, green buildings are constructed with sustainability in mind, integrating strategies like renewable energy sources and responsibly sourced materials. This approach ensures sustainability throughout the building’s lifecycle – from conception and construction to preservation, renovation, and even demolition. The primary goal of a green building is to coexist harmoniously with its natural environment.
Incorporating recycled materials, efficient water systems, and reduced energy consumption.
Relying on sources like solar panels and wind turbines for clean power generation, minimizing environmental impact
Prioritizing occupants’ well-being through low-VOC paints and proper ventilation systems.
Implementing water-efficient fixtures, rainwater harvesting, and wastewater treatment technologies.
Extending sustainability to outdoor spaces through native plantings, permeable surfaces, and green roofs.
Significant reduction in carbon footprint, waste production, and reliance on non-renewable energy sources.
Lower energy consumption and operating costs due to efficient insulation, lighting, and HVAC systems.
Improved indoor air quality and access to natural light enhance occupants’ quality of life.
Greater resale and rental values due to sustainable features and reduced operational costs.
Higher initial costs, awareness challenges, and complexities in integrating multiple sustainable technologies.
Even though the initial investment for a green building may seem to be higher, in the long run, green buildings are not only a smart choice for the environment but also for economic benefits and society as a whole. It helps create a more sustainable and enduring future while providing benefits to both occupants and investors.
Conventional Buildings: Conventional buildings adhere to traditional construction practices that often disregard energy efficiency and eco-friendly considerations. Sustainable concepts are rarely incorporated, leading to structures that consume excess energy and resources.
Minimal Use of Sustainable Materials.
Lack of energy-efficient features and systems, leading to higher operational costs.
Established and understood by industry professionals.
Generally associated with lower upfront costs.
Outdated systems and inadequate insulation contribute to higher energy consumption.
Conventional buildings contribute significantly to greenhouse gas emissions, resource depletion, and waste generation.
These structures often lack durability and fail to withstand natural disasters.
The distinction between Green buildings and Conventional buildings lies primarily in their design, construction, and environmental impact. Green buildings emphasize sustainability, energy efficiency, and environmental responsibility, while conventional buildings follow traditional construction practices with less emphasis on these factors.
Buildings account for a substantial amount of energy-related Co2 emissions. According to the International Energy Agency (IEA), the operations of buildings account for 30% of global final energy consumption and 26% of global energy-related emissions. Thus it is important to design and invest in buildings that use energy proficiently. Energy-efficient buildings are designed to minimize energy consumption while maintaining comfort and functionality, benefiting both the occupants as well as the investor.
Lower energy usage for heating, cooling, and lighting, resulting in reduced utility bills.
Contributes to reduced greenhouse gas emissions and overall environmental footprint.
Despite higher initial costs, long-term energy savings provide a positive return on investment.
Prioritizes thermal comfort, lighting, and indoor air quality.
Many regions offer incentives for energy-efficient construction, promoting sustainable practices.
Incorporating advanced technologies and materials can lead to higher upfront expenses.
Specialized expertise might be required for implementing energy-efficient systems.
Some strategies could impose constraints on aesthetics or architectural freedom.
The concept of net zero energy buildings (NZEBs) is a relatively recent development; nonetheless, it is gaining popularity because of the immense benefits to our environment and sustainability.
Several countries are swiftly adopting NZEB principles and considering making them mandatory for new constructions within a few years. In 2021, the worldwide market size for zero-energy buildings reached $71.7 billion. Projections indicate that by 2031, this figure will surge to $403 billion, demonstrating a robust Compound Annual Growth Rate (CAGR) of 18.7%.
This signifies the swift transition from an innovative concept to an imminent standard in the construction industry. NZEBs aim to generate as much energy as they consume, often utilizing renewable sources to offset grid consumption.
Generates on-site energy through renewable sources, offsetting consumption
Minimizes carbon emissions and resource consumption.
Despite initial costs, long-term energy savings lead to reduced utility bills.
Prioritizes occupant comfort.
The Indira Paryavaran Bhavan in New Delhi, which was built in 2014, holds the distinction of being India’s first Net Zero Energy Building (NZEB). It was designed with smart energy-saving techniques and a powerful solar PV system of 930 kW capacity. This solar system generates around 1,491,000 units of electricity annually. Interestingly, the building’s total energy requirement is approximately 1,421,000 units per year.
Despite the potential benefits of utilizing solar power and tackling environmental concerns, only seven Indian states, including Delhi, have successfully constructed NZEBs so far.
The major challenge in setting up a Net zero energy building is a high initial investment and technical complexity. It is important to note Implementing and maintaining such systems can be intricate.
Green buildings aim to be environmentally friendly through energy-efficient technologies and sustainable materials, whereas zero-energy buildings (ZEBs) go a step further.
ZEBs strive to produce as much energy from renewable sources as they use over a period, like a year. This means they try to balance out their energy consumption by generating their own energy on-site, making them super energy-efficient.
So in simple terms, green buildings deploy sustainable methods in constructing a building, but a zero-energy building generates its own energy and uses sustainable materials for construction.
