Green Building Materials: Choosing Sustainable Options for Construction

Green building materials refer to products and materials that are environmentally-responsible and reduce negative impacts on human health and the environment. These include materials that conserve energy, water, and other resources and reduce pollution in all stages – from manufacturing to transport to installation and eventual disposal. Let’s take a look at some of the major green building material options available.

Bamboo Flooring

Bamboo is one of the most sustainable flooring options available due to its rapid growth rate and renewable nature. Bamboo regenerates quickly without the need for replanting. It is a grass that can be harvested every 3-5 years without killing the plant. Bamboo flooring is durable, moisture-resistant and has a beautiful grain. It is a great alternative to traditional hardwood floors. Some key advantages of bamboo flooring include that it sequesters carbon while growing, requires less land and water than trees, and the culm structure makes it very hardwearing under foot traffic.

Recycled Content Materials

Green Building Materials containing recycled content divert waste from landfills and promote recycling. Examples include products made from recycled glass, plastic, steel and aluminum. Insulation made from recycled denim or newspapers is a good option. Flooring tiles containing recycled glass, rubber or tire crumb are durable and help reduce landfill waste. Using recycled content materials has lower environmental impact than virgin materials as it reduces usage of fresh raw materials and energy for processing. It is a sustainable way of “closing the loop” in material usage.

Cork Flooring and Walls

Cork is a fast growing, renewable resource that is both insulating and soundproofing. Cork floors are comfortable under the feet and provide excellent thermal and acoustic insulation. They do not contain formaldehyde, are water resistant and very durable. Cork can also be used as an environmentally-friendly alternative to drywall on walls. It regulates humidity and temperature indoors and has antimicrobial properties too. Cork harvesting does not kill the trees and allows the bark to regenerate, making it a highly sustainable material.

Hemp-Based Materials

Hemp is a very versatile plant that can be used to create a variety of construction materials including concrete blocks, insulation, panels, plasters and paints. Hemp plants absorb carbon dioxide and release oxygen all through their growth cycle. Hempcrete is a sustainable insulating material made from hemp stalks/hurds, lime and water. It is mold-resistant, fireproof and provides better insulation than fiberglass or cellulose. Hemp fibers can be mixed in plaster or used to make lightweight panels for walls too.

Renewable and FSC Certified Wood

Wood from responsibly managed forests that have received Forest Stewardship Council (FSC) certification is an eco-friendly choice. Such forests are managed according to strict environmental and social standards that promote reforestation and biodiversity. FSC certified wood products are not associated with deforestation or destruction of natural forests. Green Building Materials materials like engineered wood, cross laminated timber (CLT) and glue laminated timber are climate-friendly wood options too. They use less raw wood material and can be reused or recycled at the end of their lifespan.

Non-Toxic Paints and Sealants

Opting for low or zero VOC (volatile organic compound) paints and wood finishes/sealants protects indoor air quality. VOC emit gases that can cause adverse health issues like headaches and breathing difficulties. Choose paints, stains and sealants with minimal or no toxic chemicals. Look for products certified by schemes like Greenguard, Eco-institute or Green Seal. Natural paints based on linseed oil, milk paint or clay have zero or low VOCs. Mineral-based plasters and paints ensure a healthier interior.

Energy Efficient Mechanical Systems

High efficiency HVAC (heating, ventilation, and air conditioning) systems, insulated ductwork and ENERGY STAR certified appliances significantly reduce energy consumption compared to standard products. Geothermal/ground source heat pumps, integrated solar PV and solar hot water systems also contribute towards clean energy usage. Using a ‘whole-building’ approach in design and choosing efficient mechanical equipment lowers operational emissions over the building’s lifetime. This has long term environmental and cost benefits too.

Construction and Demolition Waste Management

Careful planning is needed to reduce waste generation on construction sites. This involves sorting, diverting recyclable waste like wood, drywall, metals and concrete from landfill. Construction waste should be reused/recycled on-site itself wherever feasible. Using prefabricated components and modular construction techniques also minimize on-site waste. It is best to hire demolition contractors who can deconstruct buildings efficiently with maximum materials recovery at building’s end of life/renovations. This follows the construction waste management hierarchy – reduce, reuse, recycle, recover.

Green Building Certifications

Buildings can be evaluated and certified according to programs like LEED (Leadership in Energy and Environmental Design), BREEAM, Green Globes etc. Certification ensures the structure was designed and built using sustainable strategies and materials. It takes a holistic view of various green aspects – energy/water efficiency, materials selection, indoor air quality, renewable options used etc. Owners of green certified properties can benefit from cost savings, marketing advantages, health and productivity gains in the long run. Certification provides a framework for developers to deliver high performance green buildings.

With careful planning and material selection, Green Building Materials can have significantly lower environmental impacts over their entire lifecycle compared to conventional construction. Choosing sustainably sourced, non-toxic, recycled content and energy efficient building materials supports a greener built environment. Combining such materials with efficient designs enables construction of net zero structures having net positive impacts on climate change, resource usage and occupant well-being.
