Transcript of LEED AP O+M IEQ Prerequisites and 1.1-1.5
Develop and maintain an IAQ management program based on the EPA's Indoor Air Quality Building Education and Assessment Model (I-BEAM)
LEED AP O+M
IEQp1 & c 1.3
#1-Prohibit smoking in the building and exterior smoking at least 25 feet from entries, air intakes, and operable windows, or
#2-Same as option 1 but add in designated smoking areas within the building that are designed to contain, capture and remove ETS. Provide periodic air testing,
#3-Prohibit smoking in common areas and, have exterior smoking areas at least 25 feet from entries, air intake and operable widows, Seal walls, ceilings, floors and vertical chases between rediential units and weather strip doors that lead to common hallways. Provide periodic air testing.
Implement a Green Cleaning Policy
Address the purchase of cleaning products and equipment
Establishes standard operating procedures
Standards for hand hygiene, safe handling and storage of cleaning chemicals, staffing and training requirements for maintenance personnel,
Continuous improvement program
Indoor Environmental Quality Overview- Prerequisites- Credit 1.5
Addresses environmental concerns related to indoor air quality, occupants' health, safety, and green cleaning practices
Establish minimum and increased indoor air quality (IAQ) performance to enhance indoor air quality in buildings. Contributing to the health and well-being of occupants
Minimum Indoor Air Quality Performance and Indoor Air Quality Best Management Practices-Increased Ventilation
Environmental Tobacco Smoke (ETS) Control
Prevent or minimize exposure of building occupants, indoor surfaces and
systems to environmental tobacco smoke (ETS)
Green Cleaning Policy
Reduce the exposure of building and maintenance personnel to potentially hazardous chemical, biological, and particulate containment, which adversely affect air quality, human health, building finishes, building systems and the environment
Documentation and Calculations
Indoor Air Quality Best Management Practices-Indoor Air Quality Management Program
Enhance Indoor Air Quality (IAQ) by optimizing practices to prevent the development of IAQ problems in buildings, correcting problems when they occur and maintaining the well-being of occupants
Provide capacity for ventilation system monitoring to help sustain occupant comfort and well-being
Indoor Air Quality Best Management Practices-Outdoor Air Delivery Monitoring
Install permanent, continuous monitoring systems that provide feedback about the ventilation system:
MECHANICAL VENTILATION SYSTEMS
Provide an outdoor airflow measurement device capable of measuring (and, if necessary, controlling) the minimum
outdoor airflow rate at all expected system operating conditions within 15% of the design minimum outdoor air rate.
MECHANICAL VENTILATION SYSTEMS THAT PREDOMINANTLY SERVE DENSELY OCCUPIED SPACES
Have a CO2 sensor or sampling location for each densely
occupied space and compare it with outdoor ambient CO2 concentrations.
NATURAL VENTILATION SYSTEMS
Locate CO2 sensors in the breathing zone of every densely populated room and every natural ventilation zone.
CO2 sensors must provide an audible or visual alarm to the occupants in the
space and to the system operator if CO2 conditions are greater than 530
parts per million (ppm) above outdoor CO2 levels or 1,000 ppm absolute.
Documentation & Calculations
High density=25 people or more per 1,000 square feet
Low density=fewer than 25 people per 1,000 square feet
High density mechanically ventilated spaces:
The CO2 level must be monitored for each space and the sampling location must be between 3 feet and 6 feet above the finished floor.
Low-density mechanically ventilated spaces:
The outdoor ventilation rate must be directly measured and compared with the minimum required ventilation rate.
Naturally ventilated spaces:
Monitoring CO2 levels in the occupied spaces in naturally ventilated buildings provides feedback to building occupants and operators so that they can adjust ventilation by, for example, opening windows.
Provide visual documentation of monitoring devices via floor plans,
schematics, elevations (where applicable) and mechanical schedules.
Track the calibration and maintenance of all airflow measurement
Be aware of and implement the manufacturer’s recommended
calibration for all monitoring devices.
Indoor Air Quality, Occupant Comfort and Green Cleaning
Many buildings are not designed with indoor environment quality in mind
Lacks occupant controls in lighting and thermal conditions
Affects energy consumption
chemicals outside the building can be brought in with outdoor air for heating and cooling
Promotes the following:
Managing air contaminants
Implementing green cleaning
Specifying less harmful materials;
Allowing occupants to control their desired thermal comfort settings; and
Providing day lighting and views
Improve indoor air quality through:
Systems effectiveness and monitoring
Building system upgrades and improvements
Three credits have exemplary performance
Know your standards!
APPA Custodial Effectiveness Audit
Three credits have PP
Create a policy that meets the LEED EBOM 2009 policy model
Interior smoking areas:
Must be clearly defined-an entire area cannot defined as a smoking area
A separate ventilation system must be installed and dedicated to this area
Negative pressure must be maintained in the smoking area
Choose tight construction
Seal any penetrations in the walls, ceilings, and floors in every unit
Seal all vertical chases adjacent to units
Equip all doors leading from residential units to common areas with weather stripping
Testing requires two standards:
Demonstrate acceptable sealing of residential units by a blower door test-ASTM Standard E 779-03
Use the progressive sampling methodology defined in the CA Residential Alternative Calculation Method Approval Manual.
All policies, regardless of building function, must prohibit smoking in the building.
DOCUMENTATION AND CALCULATIONS
Create a policy
Provide occupants details about the buildings non-smoking areas and the policy
Maintain site plans that indicate the on-site smoking policy area
Track and record testing data for any interior smoking rooms.
NOTE: This is the only prerequisite that is not eligible for a 10% floor area exemption. The whole building must comply with the ETS control requirements.
Follow IEQc 3.3 and 3.4 when reviewing purchases of cleaning products and equipment
Policy must adhere to the 2009 LEED for EBOM
Measuring CO2 concentrations to determine and maintain adequate
outdoor air ventilation rates in buildings is one recommended
method for achieving better indoor air quality.
Installing CO2 and ventilation rate monitoring systems requires an
investment in equipment, installation, annual calibration and maintenance.
However, these systems enable building owners, maintenance
personnel and occupants to detect air quality problems quickly, so that
corrective action can be taken.
Airflow monitors can help inform the commissioning agents and
the measurement and verification tools process to improve IAQ, while
minimizing energy losses.
Indoor Air Quality Best Management Practices-Reducing Particulates in Air Distribution
Reduce the exposure of building occupants and maintenance personnel to potentially hazardous particulate contaminants, which adversely affect air quality, human health, building systems and the environment
MERV rating is a measurement of filtration medium effectiveness
MERV ratings span from 1 to 16, with 16 being the highest level of efficiency
These are more effective at removing smaller particulates.
Documentation and Calculations
A maintenance plan is required.
teams must establish and follow a regular schedule for maintenance and replacement of filters
Log all maintenance and repair.
Keep product cutsheets or manufacturers information for all MERV 13 filters installed on all outdoor intakes
Indoor Air Quality Best Management Practices-Indoor Air Quality Management for Facility Additions & Alterations
To prevent indoor air quality (IAQ) problems resulting from any construction or renovation projects to help sustain the comfort and well-being of construction workers and building occupants
Requirements: Develop and implement an IAQ management plan for the construction and occupancy phases of facility alterations and additions and tenant improvements
Modify/maintain outside air intake, supply air fan, ventilation distribution system
Meet ASHRAE Standard 62.1- 2007
or, supply at least 10 cubic ft per min (cfm) of Outside Air (OA) per person
Mechanically and mixed-mode ventilated spaces
Exceed ASHRAE 62.1-2007 by 30%
Naturally ventilated spaces
Complete an airflow diagram in accordance with Figure 2.8 of the CIBSE Applications Manual 10: 2005, Natural Ventilation in Non-domestic Buildings
or, provide analytic modeling to demonstrate compliance with ASHRAR 62.1-2007, Chapter 6, in at least 90% of spaces
Determine breathing zone outdoor airflow for each zone
