Green buildings are constructed and operated to maximize resource efficiency. This means minimizing carbon emissions that contribute to global warming; decreasing natural resource extraction and energy consumption; as well as limiting waste creation.

Environmentally conscious building strategies offer numerous business advantages. Reduced operating costs, healthier environments for occupants and resilient construction that minimizes business interruption risk are just some of the tangible advantages that environmentally responsible practices bring to manufacturers and commercial businesses alike.

Energy Efficiency

Green buildings use sustainable technologies to maximize energy efficiency. For instance, photovoltaic solar panels create on-site electricity while strategically placing windows allows daylighting to add interior illumination and reduce heating costs.

Attic homes use recycled materials like steel repurposed from shipping containers or tires, and avoid toxic building products such as Portland cement, toxic wood preservatives, PVC plastics and lumber harvested without adequate environmental considerations. They may also incorporate more natural ventilation systems to reduce dependence on city water systems while improving indoor air quality.

These innovations make green buildings more environmentally-friendly, helping prevent climate change while providing organizations looking for balance between sustainability and performance. Benefits can include lower operational costs and improved occupancy levels.

Indoor Air Quality

Reducing energy use in green structures is one element of sustainability, but ensuring good indoor air quality should also be prioritized. Breathing polluted air over extended periods is known to lead to health complications like silicosis, asthma and cardiovascular disease – three potentially serious consequences of breathing polluted air for too long.

At home and work, VOC minimisation and improved ventilation reduce air pollution levels significantly and have been shown to improve cognitive functioning and productivity among occupants.

Selecting low-emission building materials such as paints with low Volatile Organic Compound (VOC) content and furnishings helps minimise off-gassing that contributes to poor indoor air quality. Utilizing smart systems that monitor temperature, humidity and pollutants helps ensure high indoor air quality without excessive energy use. In urban areas, natural ventilation methods like ventilated facades or cross-ventilation corridors may be integrated to move fresh, clean air around continuously within buildings.

Materials

Green design centers around using materials with lower embodied energy; often this involves recycling or reusing existing building materials in construction projects.

Glass with high recycled content or solar panels with lower carbon emissions can have a great environmental impact compared to new materials with higher embodied energies, while using natural resources which regenerate rapidly reduces energy usage further.

Some green buildings aim for recognized certification standards; others find environmental performance via vernacular wisdom such as passive ventilation strategies based on local building traditions, bamboo construction that sequesters carbon during growth or rammed earth walls that regulate temperature without using mechanical systems. Whatever their strategies, green buildings demonstrate that architectural ambition and environmental accountability can coexist harmoniously.

Water Efficiency

Building sector emissions contribute significantly to global greenhouse gas emissions and consumption of energy, water and materials; yet they provide one of the greatest opportunities for cost-effective improvement measures.

Green building techniques and technologies aim to reduce their building’s environmental footprint through strategies such as site selection, design, construction materials selection and utilization, operation optimization and waste reduction.

With limited freshwater supply around the world, water efficiency measures must be implemented into green buildings to achieve sustainability goals. Such measures may include using energy-saving appliances and fixtures; installing rainwater harvesting or greywater collection systems; or recycling/reclaiming used or recycled water. Taking these into consideration during conceptual stages of design projects will help designers and owners meet sustainability goals more easily.

Resilience

Everybody experiences setbacks and difficulties of various magnitudes in life, from minor problems such as not getting into college classes or declining promotions, to catastrophic disasters like hurricanes and terrorist attacks. Resilience comes from many sources – optimism, strong relationships, diet/exercise habits that align with values, etc. – so we can adapt and move on quickly when life throws us a curveball.

Green buildings provide resilience through cost efficiency and strategies that reduce risks to people and operations in an extreme weather or disaster event. Energy-efficient buildings with storage or generation capabilities can significantly lower utility prices while mitigating impacts on air quality locally.

Homes featuring resilient construction techniques may qualify for the National Green Building Standard Green+ RESILIENCE certification, providing an efficient means of third-party recognition of sustainability features including resilience.
