Green buildings employ advanced insulation, windows and energy-saving appliances to lower energy costs while taking advantage of renewable sources to decrease fossil fuel dependency.
Low-flow fixtures, graywater systems and xeriscaping are key strategies for water reduction, while green builders strive to build near transit lines and amenities in order to minimize driving distance.
Energy Efficiency
Buildings account for an excessive amount of greenhouse gas emissions, energy use and depletion of natural resources. Green buildings present an opportunity to mitigate these negative impacts by employing technologies and materials which improve efficiency and sustainability.
These include high-efficiency appliances; lighting and windows; insulation; heating, ventilation and air conditioning (HVAC) systems; WaterSense labeled fixtures, as well as renewable energy such as solar panels, wind turbines or geothermal heating that can all contribute to creating eco-friendly buildings.
Utilizing green building products, like recycled content materials and low VOC paints and adhesives, helps limit exposure to toxic chemicals found indoors, helping improve occupant health and wellbeing with decreased symptoms of asthma, allergies, stress and depression as well as self-reported improvements in productivity.
Indoor Air Quality
Indoor air quality (IAQ) refers to the level of pollutants within an enclosed building or structure’s interior environment, including particulate matter, carbon dioxide levels, volatile organic compounds and odors. A healthy IAQ environment should be free of these contaminants to provide occupants with a healthy and safe environment; poor IAQ may lead to respiratory illnesses, allergies or fatigue leading to long-term illnesses such as respiratory or fatigue related illnesses.
Green buildings prioritize IAQ by employing strategies that reduce outdoor pollution, minimize conditions for pollutants to thrive and provide efficient ventilation. This strategy includes selecting low-emission building materials, adhesives, paints and furniture as well as regularly replacing filters in order to maintain optimal filter efficiency.
Some activities, like smoking, using unvented appliances and redecorating can release pollutants intermittently into the environment. When these pollutants build up in spaces without adequate ventilation they could contribute to health issues like asthma, allergy attacks, headaches and fatigue – making green buildings prioritize air quality in order to create healthier and more productive environments for their occupants.
Durability
Sustainable building begins with choosing long-lasting materials like bamboo, reclaimed wood and recycled steel that last longer. By eliminating frequent replacement and repair needs and saving both waste and money throughout its lifespan, green building allows homes or offices to become greener more quickly.
Green materials contribute to reducing our carbon footprint, since they’re produced locally. Supporting local businesses while cutting energy consumption by cutting transportation costs are all benefits that come from choosing local products and materials.
Early research has indicated that occupants in green buildings tend to report higher levels of indoor environmental quality (IEQ) and health outcomes than occupants in conventional buildings; however, these studies rely heavily on self-report surveys without considering other variables that might skew results such as knowledge that the building is green or having small sample sizes which increases likelihood of Type II error. As this field develops further, it will become essential to develop high quality metrics that provide meaningful comparisons between green and conventional buildings when it comes to health effects on human health impacts between conventional and green buildings as well as conventional impacts on human health impacts from green and conventional buildings compared to conventional ones.
Life Cycle
Green building practices and technologies can have a substantial effect on a building’s life cycle, from materials sourcing and installation, to energy use for powering it all. To measure these impacts accurately, life cycle assessment (LCA) techniques must be utilized.
LCA (Life Cycle Assessment) is a holistic methodology which takes into account cradle-to-grave impacts, such as energy use, global warming potential, water use, air pollution levels, land degradation and waste disposal. LCA calculations rely on mass balance of building materials used in its construction that have been standardised according to geographical location; as well as energy used for extraction, processing and transportation as well as emissions generated during logistics or recycling or disposal efforts.
Operational Green Buildings allow their occupants to make an impactful statement about how much they value the environment they inhabit, by using facilities and interacting with systems of controls designed to minimize impact. This may include strategies like location efficiency, structure design efficiency, energy efficiency materials efficiency indoor environmental quality enhancement operations maintenance optimization.
