Teams organize and work as part of an integrative process by working in small groups and as a whole with iterative processes. The integrative process is a method of design and construction that involves the collaboration and coordination of all project stakeholders from the beginning to achieve the project’s sustainability goals1. The integrative process requires teams to work in small groups, such as subcommittees or task forces, to focus on specific aspects of the project, such as energy, water, materials, indoor environmental quality, and site ecology2. The small groups then report back to the whole team and share their findings and recommendations, allowing for feedback and integration among different disciplines and systems2. The integrative process also requires teams to work with iterative processes, which means that they repeat and refine the design and analysis cycles until they reach the optimal solutions that meet the project’s performance targets3. The iterative processes enable teams to explore various scenarios, test assumptions, identify synergies and trade-offs, and evaluate the life-cycle impacts of their design decisions34.

LEED BD+C: Multifamily Midrise is the appropriate rating system for residential buildings that are four to eight stories above grade1. Since the project scope includes 60% of the gross floor area, it meets the minimum program requirement of having at least 40% of the gross floor area certified2. The other rating systems are not suitable for this project because they either apply to different building types or heights23.

The best way to prevent a building’s indoor pollutant(s) is to eliminate or control pollutants at the source. Indoor pollutants are substances or particles that can adversely affect the indoor air quality (IAQ) of a building and the health, comfort, and productivity of the occupants. Indoor pollutants can originate from various sources, such as building materials, furnishings, cleaning products, combustion appliances, outdoor air, or occupant activities. Eliminating or controlling pollutants at the source can prevent them from entering or spreading in the indoor environment, which can reduce the exposure and risk for the occupants. Some examples of source control strategies are: using low-emitting materials, installing local exhaust ventilation, sealing combustion appliances, implementing green cleaning practices, and prohibiting smoking13. References: LEED v4 Green Associate Candidate Handbook1, EPA’s Indoor Air Quality3

Water closets, also known as toilets, are fixtures that use water to flush human waste into a sewer or septic system. The unit of measure for water closets is gallons (liters) per flush, which indicates the amount of water used for each flushing cycle. The water efficiency of water closets can vary depending on the design, technology, and regulation of the fixture. The LEED rating system encourages the use of water-efficient fixtures that reduce water consumption and wastewater generation12. References: LEED v4 Green Associate Candidate Handbook1, EPA’s WaterSense Toilets2
