Green Buildings: A Necessity for Sustainability in Construction

According to the 2022 Global Status Report for Buildings and Construction by the United Nations Environment Programme, 2021 marked a return to pre-pandemic construction levels in major economies. This resurgence, however, coincided with a more energy-intensive usage of buildings. Additionally, emerging economies increasingly relied on fossil fuel gases within their building operations.

Notably, the buildings and construction sector emerged as a significant environmental contributor. It was responsible for 37% of energy- and process-related CO2 emissions while accounting for over 34% of the global energy demand in 2021. These figures underscore the critical need for enhanced global adoption of mandatory building energy codes. Simultaneously, existing codes must be expeditiously aligned with the overarching goal of achieving zero emissions.

Nevertheless, a positive trend emerged amidst these challenges. In 2021, we witnessed a notable 19% upsurge in global green building certifications compared to the previous year. This increase indicates a growing recognition of the imperative for sustainable construction practices and their broader implications. The path ahead is unequivocal: The global buildings and construction sector must collaboratively undertake concerted efforts with stakeholders to attain decarbonization by 2050.

So, what are green buildings? – the innovative, sustainable solution that promises to meet the present’s needs and secure a better future for future generations!

Understanding Green Buildings

Green buildings, also known as sustainable or eco-friendly buildings, are structures designed, built, and operated with minimal negative impact on the environment while prioritizing the well-being of occupants. These structures are constructed using resource-efficient techniques, sustainable materials, and energy-saving technologies. The principles of green building encompass various aspects such as site selection, energy efficiency, water conservation, indoor air quality, waste reduction, and the use of renewable resources.

Benefits of Green Buildings

Environmental Conservation: Green buildings reduce energy consumption, lower carbon emissions, and minimize waste. These practices contribute to curbing climate change and preserving natural resources.

Energy Efficiency: One of the most significant advantages of green buildings is their energy efficiency. Incorporating solar panels, energy-efficient lighting, and advanced insulation can substantially reduce energy consumption, lowering utility bills and decreasing carbon footprint.

Health and Well-being: Green buildings prioritize indoor air quality, natural lighting, and ergonomic design. These elements contribute to improved occupant health, productivity, and overall well-being.

Long-term Cost Savings: Although the upfront costs of constructing green buildings might be slightly higher, the long-term cost savings in terms of energy bills, maintenance, and operational costs far outweigh the initial investment.

Market Demand and Value: As environmental consciousness grows, so does the demand for sustainable living and working spaces. Green buildings often command higher resale or rental values due to their perceived value and benefits.

Job Creation and Innovation: The shift toward green building practices fosters innovation and creates new opportunities for skilled workers and entrepreneurs, driving economic growth.

The Paris Agreement, Global Climate Goals, and Net Zero Emissions by 2050

The Paris Agreement 2015 is a landmark in the global fight against climate change. Concluded within the framework of the United Nations Framework Convention on Climate Change (UNFCCC), the agreement signifies a collective commitment of nations to limit global temperature rise to well below 2 degrees Celsius above pre-industrial levels, while striving for efforts to keep it below 1.5 degrees Celsius. Its core objective is strengthening the international response to the climate crisis by encouraging countries to submit voluntary Nationally Determined Contributions (NDCs) outlining their specific climate action plans. The agreement emphasizes not only mitigation of greenhouse gas emissions but also adaptation to climate change’s impacts and providing financial support to developing nations. The Paris Agreement symbolizes a collaborative, inclusive effort that bridges gaps between developed and developing countries, promoting a more sustainable and resilient future for all.

Moreover, many countries have aligned themselves to the challenge of achieving net-zero emissions by 2050. It is a paramount global objective aimed at curbing the escalating threat of climate change. This ambitious target entails balancing the amount of greenhouse gases emitted into the atmosphere with an equivalent volume removed, effectively neutralizing the impact on Earth’s climate system. To realize this goal, nations, industries, and communities must undergo a comprehensive transformation, transitioning from fossil fuel dependency to a blend of renewable energy sources, sustainable practices, and advanced technologies. This entails decarbonizing energy production and reimagining transportation, agriculture, infrastructure, and more. The path to net zero requires collaborative international efforts, innovative policy frameworks, substantial investments, and public engagement to accelerate the transition toward a cleaner, more resilient, and sustainable future for future generations.

The Role of Regulations and Certifications

Governments and organizations worldwide recognize the importance of green buildings and implement regulations and incentives to promote their adoption. Building codes, energy standards, and certifications like LEED (Leadership in Energy and Environmental Design) provide frameworks for designing and constructing green buildings, ensuring they meet specific environmental performance benchmarks.

The construction industry’s future undoubtedly lies in the hands of green building practices. By embracing sustainability and incorporating eco-friendly principles into construction projects, we can create a built environment that supports growth and development and safeguards our planet for generations to come. Our industry should abide by the UNEP’s 2022 Global Status Reports for Buildings & Construction recommendations, which state that the construction and real estate industries must implement zero-carbon strategies for new and existing buildings. Moreover, the building materials and construction industries must commit to reducing their CO2 emissions throughout their value chain. Fast-growing countries and economies need investment in capacity-building and supply chains that promote energy-efficient designs, low-carbon, and sustainable construction.
