The HPSB Guiding Principles for New Construction and Major Renovations
The Guiding Principles for New Construction addresses indoor environmental quality through ventilation and thermal comfort, specifically adherence with ASHRAE Standards 55-2004 Thermal Environmental Conditions for Human Occupancy and 62.1-2007 Ventilation for Acceptable Indoor Air Quality, as well as moisture control to minimize mold contamination and building damage. Optimizing daylighting, specifying low-emitting materials, and protecting indoor air quality during construction is made explicit. Prohibiting, through policy and signage, the ability to smoke within 25 feet of building entrances, windows and ventilation intakes is similarly advised.

The HPSB Guiding Principles for Existing Buildings
The Guiding Principles for Existing Buildings advises buildings be upgraded to meet ASHRAE Standard 55-2004: Thermal Environmental Conditions for Human Occupancy and ASHRAE 62.1-2007: Ventilation for Acceptable Indoor Air Quality among other IEQ best practices including moisture control policies, occupant controlled lighting, low-emitting material specifications, pesticide management, and environmental tobacco smoke control.

LEED for Existing Buildings: Operations & Maintenance (2009)
LEED Existing Building: Operations & Maintenance (LEED EB+OM) dedicates an entire prerequisite and credit section to enhancing the indoor environmental quality of the existing infrastructure. Implementing an assortment of Indoor Air Quality (IAQ) best management practices (BMPs) are encouraged, from increasing overall outdoor ventilation 30% to putting in place conscious management programs for both indoor and outdoor air distributions. Providing controllability of internal systems as well as access to natural sunlight is encouraged. Ensuring the IEQ of the existing building remains healthy through occupation with an effective green cleaning program is also a component of LEED-EB:O&M.

LEED for Commercial Interiors (2009)
Low-emitting materials that give off little to no harmful chemicals, such as volatile organic compounds (VOCs), are promoted in LEED for Commercial Interiors (LEED-CI) for creating a healthy indoor environment. Credits are further dedicated to providing individual controllability to 90% and 50% of the tenant occupants for the lighting and thermal systems respectfully.

LEED for New Construction (2009)
LEED for New Construction (LEED NC) highlights indoor environmental quality in a fully dedicated credit category. Construction has great effect on future IEQ. Credits are awarded for optimizing indoor air quality (IAQ) through the specification of low-emitting materials and pre-occupation flush outs. Monitoring carbon dioxide levels, employing permanent entryway systems, and increasing ventilation levels further contribute to a healthy IAQ. Providing individual control over both lighting and thermal comfort contributes beyond air quality to an overall healthy indoor environment.

Green Globes New Construction
Green Globes New Construction accounts for indoor environmental quality though the predesign, schematic design, design development, construction, contracting, and commissioning stages of the building project. Occupant well-being and a healthy environment are stressed through the evaluation of indoor and outdoor sources of pollutants as well as the accompanying acoustical conditions of the site.
Questions | |
---|---|
Is there a commitment to provide healthy indoor air? | |
Has an analysis been done of the local noise pollution levels and sources? | |
Is there a requirement that design criteria for the ventilation system meet ASHRAE Standard 62.1-2004, Ventilation for Acceptable Indoor Air Quality? | |
Is there a requirement that there be moisture control in the building to prevent mold? | |
Does the design integrate CO2 monitoring? | |
Are there local exhausts in areas where contaminants will be generated? | |
Has the Project Authority approved a building flush-out or bake-off strategy before occupancy? | |
Have practices been reviewed to minimize the noise effects on workers, the present occupants, and adjacent communities during construction? |

Is there easy access for cleaning and inspecting filters? | |
Are filters able to remove particles from incoming air (Efficiency Grade between 60% and 85% Dust Spot or a Minimum Efficiency Reporting Value (MERV) of 8)? | |
Is there a program of regular maintenance and cleaning of the cooling towers that includes monthly inspection for evidence of mold or slime? | |
Are there measures to prevent intake of exhaust fumes from the loading dock and parking areas? | |
Does the contract with the cleaning contractors specifically state that they are to use environmentally preferable cleaning materials? | |
