Based on a report from the UNEP, United Nations Environment Program, the traditional building sector contributes about 30 per cent yearly greenhouse gasses worldwide. These gas emissions may double within the next two decades if we don’t move to using Hemp.
Hemp-centered construction projects both commercial and residential are already available throughout the globe, including America. The high cost of hemp-based construction materials can be attributed to the limited vendors in the sector, which implies shipping straw across long distances.
Hemp construction materials, manufactured using the crop’s stems, are becoming more popular because they provide healthier residential places. According to America’s GBC, Green Building Council, hemp plants are non-toxic feeds that offer multiple outstanding benefits.
Hemp stems provide two crucial byproducts to the building sector. Their stringy exterior offers a cost-friendly and sustainable option when searching for insulation materials. Bast fibre hemp insulation forms an air-proof with minimum loss of heat and won’t mold. Using this insulation allows a structure to autonomously meet LEED design energy efficiency parameters. Bast fibre Hemp insulation also exhibits top-tier fire resistance and great acoustic properties.
When the stalk’s chunky inner core of shives, shivs or hurds are sliced and blended with water and lime to form hempcrete, it doubles as great hempcrete walls. Load- and non-load bearing solutions for hemp construction materials are currently available on the legal market.
Buildings erected using hempcrete are extremely energy efficient thanks to their minimal thermal conductivity and high insulation properties, studies show that one hempcrete house is almost 80% more energy proficient than the traditional build. It also reduced CO2 carbon by about 8000 kilograms annually.
Hemp-centered finished products and insulation remain energy-efficient during their entire lifetime. Hemp materials also accrue added merits of lower air-conditioning and heating costs and better ventilation.
Hemp hurd prices are expected to decline as measures for hemp straw processing kick-off to purvey higher quality hemp commodities.
