Green buildings provide many cost-effective and beneficial advantages to both the environment and their occupants, including energy cost savings and improved building performance. With pandemic attention on building efficiency increasing and rising energy prices mounting, green construction appears poised for growth.

Building green begins with choosing sustainable materials. Products made with sustainable content foster local economies while limiting shipping requirements and therefore saving energy consumption.

Energy Efficiency

Buildings account for an enormous share of global greenhouse gas emissions and energy, water, and material consumption; green buildings present an excellent opportunity to make significant cost-effective improvements across these categories.

Green buildings utilize innovative technologies such as phase change materials that absorb and release heat without external energy inputs or Trombe walls that capture solar energy during the day to conserve their energy usage. Green buildings also implement ENERGY STAR appliances, lighting, heating ventilation air conditioning systems; water efficient fixtures / low flow toilets as well as on-site renewable energy generation for maximum sustainability.

Green buildings strive to reduce waste through reduction, reuse and recycling. Their materials tend to be sustainably sourced, durable and require less transportation. Green roofs, stormwater management systems and landscaping practices that help mitigate rainwater runoff support groundwater recharge – creating lower greenhouse gas emissions while simultaneously improving water quality and decreasing waste disposal costs.

Indoor Air Quality

Green buildings promote best practices for air quality, including minimizing pollutants in the building and prioritizing ventilation strategies that prioritize human health. Green buildings also encourage non-toxic air-cleaning materials that help decrease exposure to harmful microbes, toxins, and volatile organic compounds (VOCs).

Studies have demonstrated the correlation between green buildings and improved indoor air quality (IAQ), which in turn directly improves occupants’ health, and LEED buildings; initial scientific evidence is limited but research on other green standards and health-oriented certifications continues apace.

Poor indoor air quality can have immediate adverse health impacts such as headaches, fatigue, nausea and respiratory ailments. Longer-term exposure can even increase risk for cancer and cardiovascular disease. Commercial and residential buildings alike face this global problem of air pollution exacerbated by outdated HVAC systems with inadequate ventilation or VOC-containing products and paints being sold within them.

Materials

Green building relies on selecting eco-friendly construction materials with great care, such as wool, cellulose, plywood, reclaimed wood and clay plaster with straw for strength while simultaneously minimizing environmental impacts.

Green materials provide a sustainable solution that reduces demand for virgin resources, and thus generate less carbon than their traditional counterparts.

Manufacturing and design practices that effectively utilize materials can reduce waste. Reusing and recycling save energy used to process, package and transport them.

Green buildings utilize low-emissions materials for insulation, windows and doors while limiting moisture infiltration into the building. Water-efficient landscaping uses rain gardens and bioswales that capture rainwater from streets and homes so it can infiltrate into the soil and replenish aquifers; rooftop solar panels or geothermal systems produce more energy than they consume, eliminating fossil fuel consumption altogether.

Life Cycle

Green buildings strive to reduce environmental impact throughout their entire lifecycle. These structures typically incorporate solar power, water conservation and non-toxic materials. Furthermore, green buildings take advantage of natural lighting as well as orientation strategies like strategically placing windows to take advantage of sunlight or windflow for cooling or heating purposes.

Green buildings play an integral part in mitigating greenhouse gas emissions and energy, water, and material consumption – these impacts must be reduced for sustainable development to occur globally.

Many green buildings use LEED or other internationally recognized programs to certify green construction, increasing public awareness while encouraging innovation in design, construction and operation.

Real estate investors have recently seen an increased focus on properties that meet green building standards as part of a growing trend to address investor and regulatory demand as well as ethical considerations. By investing in green buildings, investors can reduce risks while improving returns; for instance, green buildings typically have lower operating costs and require less maintenance than their conventional counterparts.
