In an era where climate change looms as the most urgent global concern, how are commercial building companies stepping up to reduce their environmental impact? Are they merely riding the greenwashing wave, or are they committing to lasting environmental change? As architects, builders, and consumers, it's crucial that we peel back the curtain and closely examine the sustainability practices of commercial building industries. In this blog post, we delve into this highly relevant issue encapsulating the intersection of construction, operation, and the environment.
It's no secret that the construction industry contributes significantly to worldwide emissions. A study from the Global Alliance for Buildings and Construction attributed nearly 40% of total global greenhouse gas emissions in 2018 to commercial construction. With another report predicting a rise in construction activities by 85% by 2030, the inevitable question stands: what is the implication for our environment?
This post will address these questions, providing a comprehensive insight into the environmental impact of commercial building industries, their sustainability practices, and whether they hold their weight in our collective bid towards an eco-friendlier future.
Understanding The Environmental Impact
Let's begin by exploring the elephant in the room — the significant environmental cost of commercial construction industries. According to the United Nations Environmental Program, construction-related practices, including materials extraction, manufacturing, transportation, and end-of-life management account for more than one-third of global energy use. Additionally, the industry is also responsible for countless water pollution incidents, noise pollution, and waste generation.
Moreover, built constructions themselves are responsible for about a quarter of worldwide carbon emissions, given the fact that they often consume significant energy for cooling, heating, and power supply. The increasing trend towards urbanization only amplifies these challenges, with city spaces contributing a substantial percentage of global carbon emissions.
The commercial building sector’s ecological footprint is undeniably large, presenting a challenge as well as an opportunity. The concern is that unless significant changes are implemented, both in construction methods and operational practices, the environmental toll is likely to increase exponentially.
Examining Sustainable Practices In The Commercial Industry
Acknowledging the environmental impact of their operations, many commercial building companies have now initiated "green" or sustainable practices into their line of work. The move towards sustainable design and construction encompasses a broad array of practices, from sourcing renewable and recycled materials, implementing waste reduction strategies, and incorporating energy-efficient technologies.
Schemes such as Leadership in Energy and Environmental Design (LEED) and Building Research Establishment Environmental Assessment Method (BREEAM) are growing in influence, attesting to a conscious, worldwide turning towards green construction standards. These certification programs recognize buildings that demonstrate environmental responsibility and resource efficiency from design conception through to operation.
Furthermore, an increasing number of commercial building companies are now committing to Net-Zero Energy Buildings (NZEB), which generate as much energy on-site as they consume over a year, effectively negating their carbon footprint.
The Pros And Cons Of Ecological Construction Practices
In implementing sustainable construction practices, there are both costs and benefits commercial building firms should consider.
The apparent benefit of green construction is the reduction in environmental harm. Over the long term, sustainable buildings are also cost-effective due to their enhanced energy efficiency and water use reduction, which can significantly reduce operating costs. Additionally, more eco-friendly buildings translate into healthier living environments, reduced waste, and stand as a public testament to the company's commitment towards tackling climate change.
On the flip side, the initial capital cost to build green buildings can be higher than conventional construction. There can be a shortage of green materials or a lack of know-how and technical skills within firms to implement sustainable techniques. Furthermore, in developing countries, regulatory structures might not yet favor green construction, posing challenges for building firms hoping to embark on sustainability journeys.
Case Studies Of Companies Paving The Way
Across the globe, numerous commercial building companies are championing the sustainability cause. One such exemplary firm is Skanska, the multinational construction, and development company that has committed to NZEB and is striving for 100% carbon neutrality by 2045.
Meanwhile, Australian construction giant Lendlease has committed to eliminating carbon from its supply chain by 2040. The company is already making strides in their sustainable practices, with many of their projects, including the International Towers in Sydney's Barangaroo district, gaining widespread acclaim for their significant ecological credentials.
What Can We Expect In The Future Knowledge
As societal awareness and government policies continue to push the sustainability agenda, the construction industry will need to adapt. More commercial building companies are likely to prioritize environmental sustainability in their practices to meet increasing client demands for green buildings and satisfy stricter regulations. While ecological construction practices might be considered as optional today, very soon they could emerge as the bare minimum!
Conclusion
The commercial building sector’s significant environmental impact is both a sobering reality and a hotbed for positive change. With skyscraping figures related to emissions, energy usage, and waste generation coupled with growing urbanization, the industry must pivot towards more sustainable practices.
While the adoption of eco-friendly construction methods and operation strategies marks a positive step forward, it is clear there's still considerable work to be done. The success of these efforts will largely depend on the collective commitment of commercial construction firms, policy-makers, and consumer populations in demanding and delivering greener buildings. In the grand scheme of things, the journey towards building a sustainable future, quite literally, continues to be built one green brick at a time.
