vocs are volatile organic compounds that can evaporate from paints, solvents, adhesives, and other building materials. They can cause health problems such as eye irritation, respiratory distress, headaches, and cancer. Limiting the concentration of vocs in the air protects the health of construction personnel by reducing their exposure to these harmful substances12.

Recycling is a strategy that can be used during the building process and after occupation to reduce waste.
Recycling involves collecting, sorting, processing, and reusing or selling materials that would otherwise be discarded as waste. Recycling can save natural resources, reduce greenhouse gas emissions, create jobs, and lower disposal costs1 . Recycling can also help to achieveLEED credits in the Materials and Resources category by reducing the amount of construction and demolition waste generated by the project or by diverting waste from landfills or incinerators.

Resource depletion is a major environmental concern related to energy use. The extraction and use of non- renewable energy resources (such as fossil fuels) can lead to their depletion over time. This is why strategies that reduce energy use or utilize renewable energy sources are important in green building practices.

Green Seal is a third-party certification program that evaluates the environmental impacts of cleaning products and services. It has standards for various categories of products, such as cleaners, paper products, hand soaps, and floor care. Green Seal certified products meet rigorous performance, health, and environmental criteria. By using Green Seal certified products, projects can reduce the exposure of building occupants and maintenance personnel to potentially harmful chemicals, improve indoor air quality, and support sustainable purchasing practices.

Offering financial incentives is a strategy that can be used to address transportation in operation and maintenance under the Location and Transportation (LT) category. The LT category addresses the location and accessibility of a project site, as well as its impacts on transportation, land use, and community connectivity. One of the credits in this category is LTCredit: Alternative Transportation - Transportation Demand Management, which rewards projects that implement programs or policies that reduce single- occupancy vehicle trips and encourage alternative transportation modes, such as public transit, carpooling, biking, or walking. Offering financial incentives is one example of such a program or policy, which can provide benefits or rewards for the employees or tenants who use alternative transportation modes, such as subsidies, vouchers, discounts, prizes, recognition, or preferential parking1 .
