A major barrier to the adoption of Geopolymer concrete in construction is the lack of long-term performance data. Field testing has been undertaken to determine the behaviour of geopolymers in different service environments and address the gaps in knowledge.
Energy is needed in industry for a number of technologies and processes, including cross- cutting technologies such as steam, motors, compressed air, pumps, heating and cooling, as well as specific processes in energy-intensive sectors (Chemicals, Iron and Steel, Cement, Pulp and Paper, Non-Ferrous Metals, and Food).
Dutch cyclists rode down the world's first bike path made entirely of discarded plastic this week, in a move aimed at reducing the millions of tonnes wasted every year. The 30-metre (100-ft) cycling path in the 1,300-year-old northern town of Zwolle contains the equivalent of 500,000 plastic bottle caps and is estimated to be two to three times more durable than traditional roads.
Evaluating building design options with a focus on simultaneously minimising life cycle greenhouse gas emissions (GHG) and life cycle cost (LCC) is difficult due to a lack of comprehensive and accessible tools. An integrated approach where life cycle GHG and LCC performance can be balanced is essential in order to optimise a building's overall life cycle performance.
There is growing concern about the effect that buildings are having on the environment. Mitigation strategies tend to focus on one life cycle stage, usually the operational stage, leaving the other life cycle stages, such as manufacturing and construction, largely ignored.
The construction industry contributes around 18% of greenhouse gas emissions, 40% of depletion of natural resources, and 25% of wastes globally. To reduce these impacts, construction industries can adopt low-carbon alternatives for construction materials and waste minimisation strategies, including the recycling of construction and demolition waste.
This note presents a method to decompose life cycle inventories derived from integrated and mixed-unit hybrid life cycle assessment. The approach extends the decomposition method described by Wiedmann by diferentiating between impacts from industries, products and processes.
Certification of green building materials is a proven and effective way to incorporate, at large scale, products that are energy efficient, have minimal ill effect on indoor air quality, and/or have other green attributes into buildings.
With urban infrastructure in urgent need of revitalization, it’s time for new thinking about how the civic realm can better serve public needs and meet environmental goals. Chinatown Green Street, in downtown Washington, D.C., is a unique demonstration project that on one city block combines advanced “green,” “complete,” and “smart” street concepts.
Modularity is a strategy recognized by the academia and the industry, and modular architecture is argued to play an important role in the development of sustainable products. The objective of this article is to explore the intersection between modularity and sustainable design from the perspective of the product life cycle.
This report compares the fuel efficiency of 20 airlines operating nonstop flights between the mainland United States and East Asia and Oceania. It extends the previous transatlantic fuel efficiency methodology to the transpacific market.
