Quality transit in LEED refers to public transportation modes that reduce greenhouse gas emissions and provide access to diverse destinations. Bicycles are considered a type of quality transit in LEED, as they meet the criteria of being low-emitting, fuel-efficient, and having a high ridership capacity. Taxis, motorcycles, and single passenger cars are not considered quality transit in LEED, as they have higher emissions, lower fuel efficiency, and lower ridership capacity than bicycles.

Explanation
According to the U.S. Energy Information Administration, space heating accounted for about 32% of energy use for all U.S. commercial buildings in 2018, followed by ventilation and lighting, each at about 10%1. Space heating is the largest single energy end use in U.S. office buildings as well2.

Optimizing daylighting and ventilation is the best answer because it can create synergies across multiple LEED topics. Daylighting can reduce lighting energy demand, improve occupant comfort, and support quality indoor environments. Ventilation supports indoor air quality and occupant health.
When considered early through an integrative process, these strategies can influence building orientation, glazing, shading, HVAC design, lighting controls, and energy performance. Local materials mainly support Materials and Resources and may not affect several categories. An energy model is valuable, but it primarily evaluates energy performance; it does not directly deliver broad sustainability outcomes by itself. Delaying sustainability decisions is incorrect because LEED success is strongest when goals, synergies, and trade-offs are evaluated early in design. Early integrated decisions help avoid costly redesign and missed credit opportunities.
