Green buildings can be cost effective, healthy and supportive of their communities. Furthermore, they help fight climate change while at the same time being one of the best ways to lower greenhouse gas emissions.
Life cycle analysis (LCA) allows us to consider all of the effects associated with building processes from start-to-finish, making LCA an increasingly essential requirement in many rating systems.
Energy Efficiency
Energy efficiency is at the core of green buildings. Utilizing eco-friendly lighting solutions and renewable energy sources helps green buildings reduce operational costs while simultaneously decreasing their environmental footprint.
Studies continue to demonstrate the many advantages of energy efficient design go beyond reduced utility bills. By employing effective IEQ optimization strategies, energy-efficient buildings can help improve occupant thermal comfort, visual comfort, acoustics and productivity – increasing occupant comfort levels as well as productivity levels and ultimately making buildings more sustainable overall.
Green building technologies can help reduce energy use and enhance indoor environmental quality (IEQ). Such strategies include natural ventilation systems, daylighting techniques, passive design strategies, low-energy HVAC and lighting systems and biophilic materials integration.
Green buildings typically can achieve zero utility bills through renewable energy sources and taking advantage of tax incentives and rebates, however their upfront construction costs tend to be higher than conventional structures. Therefore, it’s essential that green building costs be carefully evaluated against their potential long-term savings as well as potential impacts on appraised value and resale prospects of your property.
Water Conservation
Water conservation is an essential aspect of green building that helps limit wasteful use. This may involve adopting dry construction methods that forgo irrigation needs; installing low-flow fixtures like faucets and showerheads; collecting rainwater harvesting rain; as well as employing other techniques to decrease potable water usage in buildings.
These practices help prevent depletion of local watersheds and aquifers, with the goal being that all used water from buildings is returned directly back into its source through green infrastructure or recycling technology, using different approaches as necessary.
An integral aspect of water conservation is avoiding chemicals that are hazardous to both human and environmental health. Pressed wood products like particleboard and medium-density fiberboard contain formaldehyde that offgases into homes over time; green buildings use long-lasting materials like natural linoleum flooring and tile, 50 year roof materials without emitting toxic substances into the environment, etc.
Materials
Green buildings aim to use non-toxic, renewable or recycled construction materials that are non-hazardous, non-polluting and renewable; such materials should also come from sustainable sources with lower carbon and emissions production processes – for instance bamboo flooring, reclaimed wood panels and hempcrete (an innovative concrete substitute made of recycled textiles) are examples.
Site selection is also key in green design, as it helps prevent flooding, wildfires and other environmental disasters from taking place. Furthermore, green buildings include passive survivability techniques which reduce energy usage while saving residents money on utility bills.
Many green buildings feature on-site renewable energy generation systems such as rooftop solar panels and smart grids for renewable power production, in addition to heat pumps, photovoltaic arrays, and other energy-saving technologies.
Indoor Air Quality
Occupants of green buildings enjoy healthier and more comfortable environments with improved air quality. These structures are created with occupant wellness in mind and often meet LEED or WELL certification standards.
Mold, mildew, bacteria and viruses flourish in damp, poorly ventilated indoor environments and can trigger allergies or respiratory illnesses in occupants. High-efficiency filters in ventilation systems along with regular maintenance help protect building environments and limit these biological contaminants’ entry into them, thus protecting occupants against their harmful impacts on health.
Other strategies for improving IAQ in green buildings include employing low-emission building materials, eliminating potential sources of pollutants and monitoring IAQ during construction and operation. Such strategies may result in significant decreases in harmful indoor air pollutants that exacerbate cardiovascular disease symptoms and asthma attacks or COVID-19 pandemic symptoms.
