BPI-1200: Key Changes Equipment Diagnostics Unvented Heaters
Combustible Gas Detector CO measurement equipment Ambient CO monitor Diagnostics Spillage CO Measurements Action Levels Gas Leak Detection Unvented Heaters Indoor Air Quality & Ventilation

BPI-1200: Key Changes - Equipment
Combustible Gas Detector (CGD) – Section 7.1.1 UL 913, Class I, II, and III, Division 1, Hazardous (Classified) Locations Capability of detecting Lower Explosive Limit (LEL) Digital display of percentage of Lower Explosive Limit (LEL) and/or Provide an alarm when detecting combustible gas concentrations exceeding 10% Lower Explosive Limit (LEL) The Bacharach Leakator 10 that NYSERDA provided to HPwES contractors a few years ago does not meet the updated requirements. It’s only Class I not II and III. Highlight the need to confirm that equipment is UL listed to all Class structures. From Bacharach website: Leakator 10 is UL 913 Class 1, Division 1, Groups A, B, C & D ( Natural Gas - 5% by volume (50,000 ppm) 10% of NG LEL = 5,000 ppm Propane – 2.1% by volume (21,000 ppm) 10% of Propane LEL = 2,100 ppm

BPI-1200: Key Changes - Equipment
CO measurement equipment – Section 7.1.2 Equipped with nitric oxide filter (NOx filter) Ambient CO monitor – Section 7.1.3 Dedicated monitor while in work environment BA Standard only specified “Carbon Monoxide Tests CO shall be measured … using a digital gauge and measured in parts per million (ppm)” BA Standard did not specify that CO must be monitored continuously.

BPI-1200: Key Changes - Diagnostics
Combustible fuel gases – Section 7.3.2 Sample with CGD on each floor Action taken at 10% of the LEL Inform homeowner/occupants of unsafe levels Advise evacuation Auditor to leave home (all workers implied) Emergency service provider notified This will not be a procedural discussion, and certainly isn’t a comprehensive description of . The intent is to discuss changes in diagnostic testing requirements of the BPI

Indoor ambient CO – Section 7.3.3 Ambient air monitored at all times Action Levels Annex D / Table D.1.B allows for continued testing and auditing procedures to continue if CO levels are below 70 ppm. 70 ppm or greater 36 – 69 ppm 9 – 35 ppm Immediately terminate inspection Advise owner of elevated levels Occupants and auditor to evacuate building Open windows/doors Recommend opening windows/doors Emergency service provider notified Recommend that all possible sources be turned off Recommend appliance be serviced Annex D / Table D.1.B allows for continued testing and auditing procedures to continue if CO levels are below 70ppm.

Combustion Appliances – Section 7.9 Spillage assessment and CO measurement *Undiluted flue gases Appliance Type Spillage CO Measurement* Cold Vent except DWH 5 min after main burner Warm Vent and Cold Vent DWH 2 min after main burner Multiple appliances Retest all simultaneously firing appliances after 2 minutes Action Levels Annex D, Table D.1.A Section 7.9.5, Table 1 No longer limited to 60 seconds Highlight that CO is measured after 5 minutes of operation independent of vent temperature condition.

Action Levels: Spillage Combustion Appliances (Annex D,Table.1.A) Threshold Limits now comply with equipment ANSI Listing requirements. Air handler / Return duct leaks Inadequate mechanical room volume Excessive mechanical ventilation

CO Thresholds for Fossil Fuel-Fired Combustion Appliances (Section 7.9.5) 4 CO Air Free manual calculation Annex B Threshold Limits now comply with equipment ANSI Listing requirements.

Action Levels: CO Combustion Appliances (Annex D,Table.1.B) Threshold Limits now comply with equipment ANSI Listing requirements.

BPI-1200: Key Changes – Unvented Heaters
Unvented heaters – Section 7.8.4 Check appliance for ANSI Z – Gas Fired Room Heaters-Volume II (ANSI Z ) label. Recommend removal of any unvented heater that is not listed to ANSI Z Verify that the heater input is a maximum of 40,000 BTUh, but not more than 10,000 BTUh where installed in a bedroom, and 6,000 BTUh when installed in a bathroom. Recommend removal of any unvented heater that exceeds the maximum allowable BTUh as specified in Section This will not be a procedural discussion, and certainly isn’t a comprehensive description of . The intent is to discuss changes in diagnostic testing requirements of the BPI

BPI-1200: Key Changes – IAQ & Ventilation
Whole-building ventilation – Section 8.2 Determine using ANSI/ASHRAE BPI – Annex I, Determining Ventilation Requirements

BPI-1200: Key Changes – IAQ & Ventilation
Project documentation shall specify improvements as required to reduce pollution sources and to provide adequate ventilation (ASHRAE 62.2) – Section 8.3 Recommendations are required for the following: Removal of indoor air pollutants sources identified in BPI-1100, Section 8.1, or implementation of other source control measures. Sealing, gasketing, or weatherstripping all leaks between an attached or tuck-under garage and the house, including specific leakage paths as identified in BPI-1100, Section 8.2. All exhaust fan or clothes dryer (with the exception of condensing exhaust dryers) vents terminate directly outdoors. Sealing of air handler units and ducts that are located outside the pressure boundary. R-8 insulation, at minimum, for ducts located outside the pressure boundary.

BPI-1200: Summary of Key Changes
NOT perform draft testing – only spillage Need to measure CO air free NOT compare the CAZ depressurization to any threshold values Need to measure CO ambient Gas leak detection Recommend removal of unvented heaters Ventilation requirements – ASHRAE Recommended improvements for IAQ & Ventilation BPI-1200 provides the “how to” guide for completing all inspections and diagnostic tests needed to test and analyze a home. These standards are intended to work in concert with each other to provide a complete framework for standardizing the approach to inspecting and testing homes for energy efficiency and overall performance.

ANSI/ASHRAE Standard

Educating Customers on Ventilation: Whole House & Local
Interview customer see Annex F (Homeowner/Occupant Questionnaire) BPI 1200 Standard Why ventilation system is needed Where indoor pollutants come from Ways to reduce pollutant sources Signs of indoor air quality problems Location and operation of the whole-building ventilation equipment When to use local exhaust fans Measure airflow on existing ventilation General overview on educating the customer on the foe Ventilation (whole house and local)

Kitchen and Bathroom Airflow
ASHRAE Kitchen and Bathroom Airflow The standard requires exhaust fans in bathrooms and kitchens to meet the following requirements: Kitchen: 100-cfm on-demand fan or a continuous fan rated at 5 air changes per hour, based on the volume of the kitchen. Bathroom with tub or shower: 50-cfm on-demand fan or a 20-cfm continuous fan. Note: If existing home is missing this ventilation or does not have the required flow, It’s possible to install a whole-house ventilation system that complies with ASHRAE 62.2 in such a home, as long as the whole house ventilation fan has a minimum airflow rating that is large enough to make up for the “local ventilation deficit.”

Whole-building Airflow
ASHRAE Whole-building Airflow Total Airflow requirement Calculation: cfm = 0.03Afloor (bedroom + 1) or (number of occupants) Whichever is greater is the number to use Standard Sizing Table: ASHRAE Standard Review of airflow calculations. Noting it uses area of floor not volume of home.

Whole-building Airflow
ASHRAE Whole-building Airflow Example 2200 sq./ft. home 3 bedroom with 6 occupants Note: Where higher occupant densities are known, the rate shall be increased by 7.5 cfm for each additional person. When approved by the authority having jurisdiction, lower occupant densities may be used. Number of bedrooms; not to be less than one. Remember this standard is a minimum ventilation guideline. Calculation A (2,200 x .03 ) (3 bedrooms + 1) = 96 cfm Calculation B (2,200 x .03) (6 occupants) 66 + (7.5 x 6) = 111 cfm Note that you can use either table or calculated value and this example would assume local exhaust is being met per the standard allows the full infiltration credit to be subtracted from the whole building infiltration requirement. Mention that the controller timer must confirm to the Standard, note that some controllers may meet the older standard.

ASHRAE 62.2 2013 Infiltration Credit
Using blower door test results we can determine the infiltration credit for adjusting the whole house ventilation rate. Infiltration credit (Qinf) = 0.052 x CFM50 x S x wsf .052 is constant from ASHRAE CFM50 Blower test results S number of stories factor wsf weather and shielding factor Use only the wsf from ASHRAE , there are 1100 wsf factors, which are found in table B1 ASHRAE

ASHRAE 62.2 2013 Infiltration Credit Building Height Factors
Sample of New York’s “wsf” weather and shielding factor Number of Stories Story Factor (S) 1 1.5 1.18 2 1.32 2.5 1.44 3 1.55 BPI-1200, Annex I.1.4 ASHRAE , Table B1 Use only the wsf from ASHRAE , there are 1100 wsf factors, they are found in table B1 ASHRAE Note building Height: “vertical distance between the lowest to the highest above grade points within the pressure boundary.” “vertical distance between the lowest to the highest above grade points within the pressure boundary.” EqLA = (CFM50 X 0.055)/144.

ASHRAE 62.2 2013 Requirements Alternative Compliance Path
Method of meeting local exhaust requirements in kitchens and bathrooms that do not have existing local ventilation. 20 CFM credit for 1 window in kitchen, or bath Local ventilation deficits will be added together, and (a portion) will be rolled into whole house ventilation requirements. Review the Alterative compliance and the sone requirements. Explain how we are going to review examples of this alterative compliance. Required Additional Airflow The total airflow deficit is the sum of all the final airflow deficits from the all bathrooms and kitchens. The required additional whole building ventilation airflow is equal to one-quarter of the total airflow deficit. A Sone is a measurement of sound in terms of comfortable hearing level for an average listener. The lower the Sone value, the more comfortable the listening environment. Sones are not decibels or volume, but rather how sound is "sensed". One Sone is the equivalent of a quiet refrigerator.

Measuring System Airflow
ASHRAE Measuring System Airflow Review the different types of air flow measuring devices.

ASHRAE 62.2 2013 Examples 90 cfm Whole-House ventilation REQUIREMENT
2000 sq./ft. home in Albany, NY 3 bedroom with 4 occupants 2 story with a Blower door of 1000 cfm50 Measured kitchen exhaust of 100 cfm & one bath with 50 cfm Whole house ventilation requirements with using infiltration credit: Total calculated - Infiltration credit = 90 – 42 = 48 cfm minimum required of whole house ventilation. Demand controlled - As long as the intermittent cycle runs at least every three hours, the adjustment is proportional. If the cycle is longer, there is a penalty. Infiltration Credit (Qinf) 0.052 x CFM50 x S x wsf 0.052 x 1000 x 1.32 x .61 41.87 cfm = 42 cfm CREDIT Calculation 0.03Afloor (bedroom + 1) (2000 x .03) (3 bedroom + 1 ) -> 90 cfm Whole-House ventilation REQUIREMENT From Table 4.1a 90 cfm Whole-House ventilation Note that you can use either table or calculated value and this example would assume local exhaust is being met per the standard allows the full infiltration credit to be subtracted from the whole building infiltration requirement. Mention that the controller timer must confirm to the Standard, note that some controllers may meet the older standard.

ASHRAE Calculator Will explain in later slides how and where they can get this calculator and others like it. Note that this calculator comes with video tutorials.

ASHRAE 62.2 2013 Examples Example 2 2500 sq./ft. home in Albany, NY
3 bedroom with 4 occupants 2.5 story with a Blower door of 2000 cfm50 No Kitchen exhaust & one bathroom (no fan) with a window Whole house ventilation requirements with existing ventilation using infiltration credit: The standard allows for a alternative compliance which allows to calculate a deficit for local ventilation and add this to the whole house ventilation system. In this example we have a deficit of -100 cfm and -30 cfm (50-20=30) total 130 cfm. This deficit is divided by 4 (130/4=32.5cfm). This deficit is added to the Ventilation requirement ( = cfm which is the require whole house and local ventilation rate. Total calculated – Infiltration credit = – 91 = 46.5 cfm minimum required whole house ventilation. Infiltration Credit (Qinf) 0.052 x CFM50 x S x wsf 0.052 x 2000 x 1.44 x .61 91.35 cfm = 91 cfm CREDIT Calculation 0.03Afloor (bedroom + 1) (2500 x .03 =75) (3 bedroom + 1= 4) 105 cfm Whole-House ventilation From Table 4.1a 105 cfm Whole-House ventilation Note that you can use either table or calculated value and this example would assume local exhaust is being met per the standard allows the full infiltration credit to be subtracted from the whole building infiltration requirement. Mention that the controller timer must confirm to the Standard, note that some controllers may meet the older standard.

ASHRAE Calculator Explain the alternative compliance and note the timer setting along with how the standard leaves it up to the contractor to locate the ventilation system and also what type of ventilation system to use.

Applying ASHRAE 62.2 2013 to NY HPwES
Contractor must offer the option of mechanical ventilation according to ASHRAE procedures. Customer must be educated in the effects of the mechanical ventilation approach, including any required maintenance, and be receptive to installation.

Applying ASHRAE 62.2 2013 to NY HPwES
In all instances the contractor must prioritize air sealing activities that: Isolate attached garages from the conditions space Isolate unheated attics from the conditioned space Isolate pollutants from the conditioned space Create air flow patterns that are conducive to fresh air distribution throughout the dwelling

BPI-1200 Implementation in the HPwES Program

Implementation: Timeline
January 1, 2016 Recommend removal of unvented space heaters that exceed maximum allowable BTU/hr New standards for spillage assessment Elimination of requirement to test draft Ventilation recommendations according ASHRAE New projects started after May 1, 2016 must comply with BPI's new testing requirements. Ambient fuel gas and pipeline testing Ambient CO readings and actions

Implementation: Forms
Post-Installation Health and Safety Test Results Use existing form until an updated one is released Indicate that CO is air free as necessary by adding AF after the measurement

Implementation: MIG The MIG is intended to serve as a consensus based, standardized, minimum work specification, as defined by NYSERDA and program contractors. Once established, the MIG provides the “playbook” for both the contractors and the program to agree upon what constitutes acceptable work, and minimize the subjectivity.

Implementation: MIG Review
NYSERDA has begun a review of the Materials and Installation Guidelines (MIG) used for the Home Performance with ENERGY STAR and EmPower New York programs. The review team consists of NYSERDA Quality Assurance and Program staff, Implementation staff from Honeywell and CLEAResult, BPI staff and contractor representatives. The goals are as follows: Review concerns expressed by participating contractors and revise accordingly Incorporate BPI 1200 requirements Identify current requirements that would better be identified as best practices, allowing for greater innovation Clarify when BPI requires that contractors implement measures, and when BPI only requires that contractors evaluate measures Edit and correct as needed There is an active MIG review initiative going on Pat Dundon has provided significant insight to foam related applications and Kelvin should be issuing a technical memo on this in near future. Although he will revisiting the entire document he will release memo’s on each independent section and he will ask for insight from a rotating contractor base.

Implementation: MIG Revisions to Date
Slope Ventilation The MIG does not allow for dense-packing slopes with ventilation. This determination was made in consultation with NYS Codes officials, DOE, and experts in the field, in recognition of the importance that slope ventilation be included with this measure. NYSERDA is generating a technical bulleting to be reviewed by NYS Codes. Once this is reviewed and finalized NYSERDA will issue a program notice to all participating contractors.

Asbestos and the Use of a Blower Door The presence of ALM does not necessarily preclude the use of a blower door in a dwelling. However, the presence of suspected friable asbestos-containing building materials that are damaged or in a deteriorating condition disqualifies the home from blower door tests, duct pressurization tests or any activity that could potentially introduce asbestos fibers into the living space. Blower door tests must not be conducted if suspected friable asbestos-containing materials are at risk of being drawn into the living space. *Vermiculite is friable and can become airborne with little disturbance.

Steam and Hydronic Heating Pipe Insulation Upon review and in consultation with BPI, it is not their intent to require heating pipes to be insulated on every job, but rather that the potential benefits of the measure be considered with the customer. NYSERDA recognizes that a contractor and customer may agree on a workscope that does not include the measure. NYSERDA finds as follows: Contractors must identify the potential benefits of insulation of steam or hydronic heating pipes in unconditioned areas or semi-conditioned areas (such as basements). Uninsulated steam pipes in unconditioned or in semi-conditioned areas can negatively impact the performance of a steam system. When there are performance problems with a steam distribution system, it is strongly recommended that a contractor encourage the customer to insulate the steam pipes in these areas both for energy savings and system maintenance. NYSERDA will be providing further guidance on this issue in the near future. Potentially table this slide

Implementation: MIG Questions
Core Sampling This is the process of weighing samples of wall insulation to ensure that the proper density has been achieved. This practice is not required of contractors; it is employed on occasion by the Quality Assurance team, and may be considered a “best practice” for contractors. Contractors are encouraged to assure proper insulation densities and depths by performing area and volume calculations and “bag counts”. This has come up in the past in other meetings.

Implementation: MIG Question
Mold like substance in the Attic In situations where more than 10 sq. ft. of mold like substance exists in the attic, contractors may proceed with measures that may impede mold growth, such as: Air sealing and insulating the attic floor. Eliminating the source of moisture. However abatement should be handled by an appropriately trained and certified Mold abatement contractor

Attic Hatches The MIG will continue to require attic hatches with an R-value of R-14 or greater. Alternatives with a lower R-value may only be considered in situations where the construction of the attic (for example, cross-bracing) impedes the use of a hatch with the required R-value. Existing or installed attic hatches must be weather-stripped and insulated but not permanently sealed. If access to the attic is created that must be permanently sealed (such as access through drywall, or situations where the contractor insulates the attic through a vent), the contractor must provide pre- and post-photos of the installed insulation..

Water Heater Control Marking Marking the previous location of the water heater temperature setting will be treated as a “best practice” rather than as a requirement.

Implementation: QA Inspections
Quality Assurance Inspectors review projects via BPI-1200 and the MIG. Contractors are notified of inspections if the customer consents Scheduled based on the homeowner’s availability View this as value added and encourage customers to agree to the QA inspections Overall inspection rates are viewed as an annual rate and inspections might not be evenly spread throughout the year. 10-20% of jobs inspected. The QA team questions the customer and allows them to invite the contractor to be present for all inspection. If you’re not notified or requested to attend it means the customer has declined their participation in the QA visit

Job Score Reports (JSR) Issued after every QA inspection Does NOT require action Scoring Scale: 0-100 Assessment Quality: 10% Work Quality: 70% Health & Safety: 20% Scoring system information is set to be delivered to the contractor base as soon possible. NYSERDA has tasked their QA team for QACSS user guide and scoring information.

Corrective Actions Reports (CAR) Requires resolution in 30 days Photo documentation of Health & Safety corrections required Where do you upload the signed document to resolve the CAR

Clarifying and Disputing Results QACSS has a mechanism to dispute items on your CAR can be done at the action item level. If you need specific instruction please contact your account manager. The information provided will be reviewed and a decision will either be made or additional information may be requested. Encourage AM outreach

Internal QC Avoiding CARs
Have contract in hand at test-out Check to make sure that EVERYTHING contracted for was provided and/or installed. Bring test-in data sheet to test-out Test-out data can be compared with test-in data to help resolve questionable test results. Give crew/installers a copy of deliverables (contract with pricing removed) This empowers them to make sure everything on the contract is fulfilled. QC checklists may be forth coming from NYSERDA as a guide or best practice but don’t let that stop you from starting your own and implementing it with your staff.

Possible Misconceptions
Myth The Contractor Help Center used to track contractors for punitive reasons. Fact The Contractor Help Center was created to provide a more timely, efficient means of communication. Tickets are used to identify common concerns and training needs, so that they can be addressed.

Possible Misconceptions
Myth Negative feedback increases QA inspections. Fact Constructive feedback is welcome and encouraged. If you feel that your company is being over inspected let us know. Feedback increases QA inspections Contractors are leaving the Program

Clearing Up Misconceptions
Myth Contractors are leaving the Program in overwhelming numbers. Fact There has not been a noticeable drop in participating contractors. NYSERDA is taking a stronger stance on contractors not meeting their participation agreements especially when it involves not resolving QA CARs and customer concerns.
