Now, the sector is off track to decarbonize by 2050.
The road construction and maintenance industry consumes tons of carbon-intensive concrete every day to secure road-side and urban infrastructure. As populations grow this infrastructure is becoming increasingly vulnerable to impact from vehicles, creating an ever increasing cycle of damage and waste and ever increasing consumption of concrete ...
Sustainable construction aims to reduce the negative health and environmental impacts caused by the construction process and by the operation and use of buildings and the built environment. [1] It can be seen as the construction industry's contribution to more sustainable development. Precise definitions vary from place to place, and are ...
Green building (also known as green construction, sustainable building, or eco-friendly building) refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. [1]
Asphalt, concrete, glass and steel are among the most carbon-intensive construction materials. They account for nearly half of all U.S. manufacturing greenhouse gas emissions, according to the GSA.
A carbon footprint (or greenhouse gas footprint) is a calculated value or index that makes it possible to compare the total amount of greenhouse gases that an activity, product, company or country adds to the atmosphere. Carbon footprints are usually reported in tonnes of emissions (CO 2-equivalent) per unit of comparison.
Embodied carbon may be reduced in concrete construction through the use of Portland cement alternatives such as Ground granulated blast-furnace slag, recycled aggregates and industry by-products. Carbon-neutral, carbon positive , and carbon-storing materials include bio-based materials such as timber , bamboo , hemp fibre and hempcrete , wool ...
A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site [1] [2] or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows ...
