24. Combustion minimization
To reduce occupant exposure to combustion-related air pollution from heating and transportation sources.
Although wood and gas fireplaces have aesthetic benefits, they can also be detrimental to indoor air quality. If not effectively sealed off from the living space, they can contribute harmful combustion byproducts such as carbon monoxide and particulate matter. Carbon monoxide has 210 times the binding affinity for hemoglobin compared to oxygen, and thus prevents oxygen from being delivered to the body, leading to hypoxia—lack of oxygen delivery to body tissues that can cause nausea, loss of consciousness and death. Carbon monoxide leads to about 170 non-automotive fatal poisonings in the U.S. every year.
The following are forbidden in regularly occupied spaces:
All combustion equipment used in the project for heating, cooling, water-heating, process heating or power generation (whether primary or back-up) must meet California’s South Coast Air Quality Management District rules for pollution:
Signage, visible from pick-up, drop-off and parking areas indicates:
To reduce particulate matter emissions from both on-road and non-road diesel fueled vehicles and construction equipment, the following requirements are met:

The EPA notes that under certain conditions, combustion appliances such as heaters, ranges, ovens, stoves, furnaces, fireplaces, water heaters and clothes dryers can release contaminants into the home that can seriously damage health.
The South Coast Air Quality Management District Rule 1110.2 (amended 9/7/2012) establishes requirements for gaseous- and liquid-fueled engines for the purpose of reducing emission of oxides from nitrogen, VOCs and carbon monoxide.
The South Coast Air Quality Management District Rule 1111 (amended 9/5/14) establishes requirements for natural gas fired, fan-type central furnaces for the purpose of reducing emission of nitrogen oxides.
The South Coast Air Quality Management District Rules 1121 (amended 9/3/04) and 1146.2 (amended 5/5/06) establish requirements for emissions of nitrogen oxides from residential natural gas-fired water heaters and large water heaters.
The South Coast Air Quality Management District Rules 1146.1 (amended 11/1/13) and 1146.2 (amended 5/5/06) establish requirements for the reduction of emissions of oxides of nitrogen from boilers, process heaters and steam generators.
USGBC's LEED v4 Pilot Credit 75: Clean Construction requires non-road diesel engine vehicles on site that are 25 horsepower and greater to comply with the US EPA Tier 4 PM emissions standards, or a local equivalent.
USGBC's LEED v4 Pilot Credit 75: Clean Construction requires 95% of all diesel engine contractor/subcontractor vehicles meet the requirements set forth in the US EPA model year 2007 on-road standards, or a local equivalent.
USGBC's LEED v4 Pilot Credit 75: Clean Construction requires all equipment, vehicles and loading/unloading to be located away from air intakes and operable openings of adjacent buildings.
