SAINT PAUL SUSTAINABLE BUILDING POLICY
BACKGROUND
SAINT PAUL SUSTAINABLE BUILDING POLICY
Background
• Indoor environmental quality (IEQ) is an essential
part of providing a healthy and comfortable
environment for residents and employees.
• The Saint Paul Overlay has four indoor
environmental quality sections:
– Ventilation requirements
– Construction Indoor Air Quality (IAQ)
management plan
– Selection of low-emitting materials
– Thermal comfort
SAINT PAUL SUSTAINABLE BUILDING POLICY
Ventilation requirements
• Exhaust pollutants
• Mitigate negative health effects
• Manage moisture
SAINT PAUL SUSTAINABLE BUILDING POLICY
Construction IAQ management
• Manage dust and pollutants created during
the construction process.
• Minimize exposure to construction hazards
both to the occupants of the building and
workers during construction.
SAINT PAUL SUSTAINABLE BUILDING POLICY
Low-emitting materials
• Limit the amount of pollutants entering the
indoor environment.
SAINT PAUL SUSTAINABLE BUILDING POLICY
Thermal comfort
• Thermal comfort requirements set limits on
radiant temperature, air temperature, and
humidity, based on building type and a variety
of other factors.
• Intended to provide a comfortable indoor
environment for most occupants.
SAINT PAUL SUSTAINABLE BUILDING POLICY
Specific requirements: Indoor
environmental quality
• ASHRAE standards 62.1 and 62.2
– Define appropriate rates of ventilation
– Commonly incorporated into sustainable building
standards
SAINT PAUL SUSTAINABLE BUILDING POLICY
Specific requirements: Construction
IAQ Management
• During-construction:
– Establish a plan of construction IAQ management
– For buildings occupied while under construction,
follow the SMACNA IAQ guidelines
– Includes specific requirements if not outlined in
guideline or rating system
• Post-construction IAQ management: requires
a pre-occupancy “Building Flush Out” period
SAINT PAUL SUSTAINABLE BUILDING POLICY
Specific requirements: Low-emitting
materials
• Limit the amount of Volatile Organic
Compounds (VOCs) including formaldehyde
present in building materials.
– Primarily achieved through product selection,
typically of paints, adhesives, wood products,
carpet and other interior finishes.
SAINT PAUL SUSTAINABLE BUILDING POLICY
Specific requirements: Thermal
Comfort
• ASHRAE Standard 55
– Defines the range of indoor thermal
environmental conditions acceptable to a majority
of occupants.
SAINT PAUL SUSTAINABLE BUILDING POLICY
GENERAL REPORTING
REQUIREMENTS
SAINT PAUL SUSTAINABLE BUILDING POLICY
General reporting requirements:
Ventilation
• Use the Indoor Environment Quality
Worksheet found at:
– www.sustainablebuildingpolicy.umn.edu/saintpaul
• Include a list of spaces found in the project,
their required ventilation rates per ASHRAE 62
and the ventilation rate as designed.
• Submit the completed Worksheet to DSI and
PED
SAINT PAUL SUSTAINABLE BUILDING POLICY
General reporting requirements:
Construction IAQ management Plan
• Submit the required IAQ construction
management plan.
– Indicate in bid and construction documents that
compliance with the Construction Indoor Air
Quality Management Plan is required.
– The Template for construction IAQ management
plan is available at
www.sustainablebuildingpolicy.umn.edu/saintpaul
– Submit completed plan to DSI and PED
SAINT PAUL SUSTAINABLE BUILDING POLICY
General reporting requirements:
Low-emitting materials requirements
• List the products which have been specified for the
the project, along with product type and and method
of verification of compliance ( please list the
database of compliant materials in which the product
appears, or the certification that the product has
recieved).
– Template for Materials Selection Log available at
www.sustainablebuildingpolicy.umn.edu/saintpaul
– Required for products listed under each rating system, specific
requirements vary.
– Submit completed log to DSI and PED
SAINT PAUL SUSTAINABLE BUILDING POLICY
General reporting requirements:
Thermal comfort
• List all spaces in the building, their designed high and low
temperature set points during occupancy, air speed and
relative humidity, verifying that they are within the required
comfort zone for compliance with ASHRAE 55. For spaces
where mean radiant temperature or other indoor comfort
factor may be an issue, list strategies to maintain indoor
surface temperatures within 20 degrees Fahrenheit and
mitigate other comfort factors.
– Template available at
www.sustainablebuildingpolicy.umn.edu/saintpaul - note that this is a
shared template with the ventilation requirement.
