The societal challenges related to resources in sustainable construction include the impact of the construction sector on energy, CO2 emissions, material waste, water, and land use.

The barriers include disciplinary compartmentalization, constricted research timelines, and the current state of the art technologies.

In the US, 38.9% of the total energy use derives from the construction sector.

<p>The construction sector has a significant impact on CO2 emissions due to the energy-intensive nature of construction activities and the use of materials with high embodied carbon. For example, the production of cement, a key construction material, is a major source of CO2 emissions. Additionally, construction activities generate a substantial amount of material waste, including unused materials, packaging, and demolition waste. These factors contribute to the environmental footprint of the construction sector and highlight the importance of sustainable construction practices to mitigate these impacts.</p> Signup and view all the answers

<p>Existing barriers to the full realization of sustainable building technologies include disciplinary compartmentalization, constrained research timelines, and the reliance on current state-of-the-art technologies. These barriers hinder the widespread adoption and implementation of sustainable building technologies in the construction industry. To address these barriers, interdisciplinary collaboration and knowledge sharing among different disciplines should be promoted, research timelines should be extended to allow for comprehensive evaluation and development of sustainable technologies, and investment in innovative, advanced sustainable technologies should be encouraged to overcome the limitations of current state-of-the-art solutions.</p> Signup and view all the answers

<p>The construction sector exerts pressure on water resources through the consumption of water for construction activities, as well as the generation of wastewater and runoff during the construction process. For example, concrete production requires significant amounts of water, and construction sites often contribute to soil erosion and water pollution through sediment runoff. Additionally, the demand for water in construction can strain local water supplies, especially in regions facing water scarcity. These challenges underscore the need for sustainable water management practices and the adoption of water-efficient construction techniques to minimize the impact of the construction sector on water resources.</p> Signup and view all the answers

<p>Green building evaluation systems play a crucial role in promoting sustainable construction practices by providing standards and frameworks for assessing the environmental performance of buildings. These systems incorporate criteria related to energy efficiency, water conservation, material selection, indoor environmental quality, and site sustainability. By incentivizing and certifying buildings that meet these criteria, green building evaluation systems encourage the implementation of sustainable design and construction practices. The benefits of these systems include reduced environmental impact, improved occupant health and well-being, and long-term operational cost savings for building owners and users.</p> Signup and view all the answers

<p>The construction sector's impact on land use presents challenges in sustainable construction due to the extensive use of land for building development, infrastructure projects, and associated transportation networks. Construction activities often result in land fragmentation, habitat loss, and alterations to natural landscapes, which can have adverse effects on biodiversity and ecosystem services. Furthermore, urban sprawl and the conversion of natural land for construction contribute to the depletion of green spaces and agricultural land. For example, the expansion of urban areas can lead to the loss of valuable habitats and increased pressure on undeveloped land. Sustainable construction practices should aim to minimize the negative impact of construction-related land use by promoting compact, efficient development, preserving green areas, and implementing measures to mitigate habitat disruption and ecosystem degradation.</p> Signup and view all the answers
