Green buildings are part of sustainable urban development that contribute to mitigating climate change. They reduce energy and water usage as well as supporting more responsible supply chains.
Prioritize recycled and renewable materials to minimize demand for virgin resources, as well as low-VOC paints and finishes that improve indoor environmental quality.
Energy Efficiency
Energy-efficient building designs reduce upfront energy needs for powering a structure, cutting utility bills and environmental impact while simultaneously decreasing maintenance costs and prolonging its life span – an attractive feature both developers and occupants appreciate.
Energy conservation features use innovative materials and renewable resource incorporation to drive significant increases in building energy performance. Utilizing strategies such as optimized daylighting or passive design techniques allows buildings to function with reduced energy needs.
Green construction practices support a broader sustainability vision by taking an holistic view of material impacts from conception to disposal/recycling, including energy consumption, carbon emissions and water use.
Water Efficiency
Green buildings can help mitigate greenhouse gas emissions, energy consumption and water use caused by buildings worldwide. By conserving scarce natural resources and improving human health and wellbeing, these green structures contribute significantly to improved human health and wellbeing.
Outdoors, green buildings often utilize native and drought-tolerant landscaping (xeriscaping) to minimize their water use, while low-flow fixtures and appliances, onsite wastewater recycling systems and on-demand wastewater recycling can significantly lower potable water consumption.
Many green buildings also include rainwater capture and grey water recycling strategies to ease pressure on local water resources, while often including design features to return stormwater back into its source – for instance permeable landscapes and wetlands that recirculate stormwater directly back into its original source – making these strategies especially valuable in areas with limited freshwater supply.
Indoor Air Quality
Green buildings often prioritize indoor air quality by employing techniques such as source control, ventilation, air filtration and moisture management to achieve it. Indeed, IAQ plays an integral part of many certification programs like LEED, WELL and BREEAM certification schemes.
Green buildings use ventilation systems designed to continuously replace the indoor air with fresh outdoor air, thus lowering pollutant concentrations and helping regulate humidity levels, thus preventing mold and mildew growth that could compromise indoor air quality (IAQ).
Studies comparing IAQ in green buildings with that in regular (non-green) buildings have had mixed results. One such study reported that although residents in green homes reported greater satisfaction with IAQ, no significant differences in concentrations of PM2.5, black carbon, sulfur, ultrafine particles or formaldehyde were detected immediately post renovation between the two groups when measured immediately afterwards.
Materials
Green buildings go beyond being responsibly sourced; they use materials with reduced embodied energy through life cycle analysis (LCA), which analyzes products over their entire life cycles.
LCA helps identify alternatives to commonly used building materials with high carbon emissions, like cement and wood, such as plant-based foams or the innovative concrete replacement known as “ferrock”, made from waste steel silica.
Building industries are some of the most polluting, but this doesn’t have to be. Employing eco-friendly construction techniques allows manufacturing leaders to significantly lower long-term costs while meeting sustainability compliance standards.
Environmental Impact
Green buildings contribute to sustainable urban development by supporting environmental and climate goals of their locale. This means careful siting to avoid flood or fire hazards as well as encouraging alternative transportation modes such as bicycle sharing. Furthermore, they minimize energy, water and materials usage while simultaneously reducing waste production and pollution levels, and optimizing reuseability of building elements.
Green building also addresses site hydrology by incorporating rain gardens, green roofs and permeable pavement into their design to prevent polluted runoff and reduce potable water needs. They minimize irrigation requirements as well as use drought-resistant landscaping techniques that reduce their consumption of potable water supplies.
Green buildings can significantly benefit human health by optimizing indoor environments and reducing air pollutants that trigger asthma, allergies and other respiratory ailments. Self-reporting studies also indicate that employees working in green buildings tend to be happier and more productive than employees working elsewhere.
