Green buildings go beyond current building codes by using premium materials that are more durable, cutting maintenance and replacement costs while prioritizing healthy ventilation and natural sunlight for increased mood-boosting.
Traditional building materials emit formaldehyde and other chemicals which may be hazardous to human health. Green builders employ products which emit far fewer emissions or other pollutants.
Energy Efficiency
At the core of green building lies energy efficiency and reducing its environmental footprint. This includes using renewable sources like solar panels or wind turbines, using natural lighting and ventilation systems to lower energy consumption and making smarter material choices during construction.
Green buildings may utilize technologies like phase change materials that store and release heat at different points throughout the day, or Trombe walls which absorb sunlight during the day and emit it later at night – these innovations help conserve energy while providing more comfortable work environments for their occupants.
As energy efficiency technology becomes more readily accessible and affordable to implement into new and existing structures, companies are beginning to reap the financial advantages associated with green buildings – reduced utility costs and operating expenses can both lead to savings that can be substantial, especially if an analytics-driven building management system is used that ensures HVAC and lighting controls are set according to real-time occupancy data. This can increase savings considerably.
Long-Lasting Materials
Use of durable and long-lasting materials is at the core of green building. This reduces replacement needs and energy costs associated with procuring and transporting new materials to sites. Furthermore, this helps preserve nonrenewable resources while mitigating environmental impacts associated with extraction, creation and processing.
Sustainable projects also emphasize using locally available materials (reducing transportation energy costs), recycled and refurbished goods, natural or renewable materials and biological compounds that form within structures to serve practical functions like self-mending concrete and living walls, etc. Emissions testing of products is an integral component of selecting green building materials and required by many green rating systems such as LEED, Green Globes, WELL or the Cradle-to-Cradle standard.
There is now more available information regarding the health, sustainability and wellness characteristics of various building materials – often referred to as product transparency data – than ever before. While manufacturers provide this data directly through their websites, using dedicated sources like Mindful Materials or UL Spot may be more efficient for this type of research.
Indoor Air Quality
Green buildings during construction use large volumes of outdoor air to flush away odors and toxins produced from new materials, such as flooring, paints, caulks and sealants used. This helps create an air quality conducive to work until its ready for occupants.
Once a building is complete, its occupants must ensure its environment meets high indoor environmental quality (IEQ) standards. Green building design programs usually include IEQ requirements such as providing adequate fresh air intake, restricting access to sources of VOCs and formaldehyde emissions, controlling relative humidity levels and temperature, among other criteria.
Initial scientific studies demonstrate that occupants of green buildings report greater satisfaction with IEQ compared to conventional buildings; however, these studies contain limitations that make it hard to ascertain which design elements contribute most directly to improved IEQ and health – most studies rely on self-reports from occupants rather than performing any sort of matching between groups of buildings.
Water Efficiency
One of the primary components of green construction is minimizing natural resource usage during building processes. This can be accomplished in various ways, including using recycled building materials and decreasing energy use.
Implementing sustainable water systems into green buildings is another means of achieving environmental sustainability. Greywater systems collect and treat waste water before using it for non-potable uses such as toilet flushing or gardening irrigation; rainwater harvesting systems collect rainwater harvesting.
Many green buildings also employ low-flow plumbing fixtures such as shower heads and urinals that use less water, while sensors detect any leakage or when no one is using it. Furthermore, several green buildings employ innovative technologies like bi-facial solar panels or building integrated photovoltaics that serve both as aesthetic features and power generators to reduce carbon emissions as well as our dependency on traditional power sources.
