The USGBC decided to force several v2009 projects into using tools they developed for LEED v4. Higher values are higher activity levels (Health Clubs are at 20 CFM/person). Using this methodology, the documentation required for EQp1 would include documentation showing that the alternate code is at least as stringent than ASHRAE 62.1-2007 (2004 for LEED-v2) in its entirety, confirmation that all of the mandatory requirements of the alternate code have been met, a narrative describing the engineered ventilation modeling approach, and evidence documenting that the plans have been approved by the local code authority. All of the above items are preventable and not in conflict with the language in the LEED IAQ Testing Requirements. Project eligibility 091123(pdf) Guidance for multiple single family homes(pdf) Registration for multiple single family homes(xls) Registration Video(YouTube) Affordable Home Program Detail(pdf) )For high-rise residential projects attempting to show compliance for EQp1 using positively pressurized corridors that are provided with excess outdoor air [above ASHRAE 62.1-2007 (2004 for LEED-v2) minimum requirements] that is to be transferred into each living unit either via undercuts in the entry doors, transfer air grilles, or some other means, the project team must document that all mechanically ventilated spaces will meet the minimum ventilation requirements of ASHRAE 62.1-2007 (2004 for LEED-v2) Section 6.2. The documentation must also clearly identify how the ventilation design has been engineered to meet the intent of ASHRAE 62.1 where the requirements of Section 5.1 have not been met. Also, Is there any updated "62MZCalc.xls" (Revised April, 2011) for 62.1 - 2007? 2. 6. Credit. For a space designed to be naturally ventilated, can operable windows or vents be used to satisfy the 62.1-2007 requirements? If using prescriptive compliance paths (Options 2 or 3), leave the Design energy consumption and cost values blank in the Target Finder website, and set the Design values equal to the Target values in this form. To get your plaque, start with the right toolkit. 17. This means you are now looking for a space type with a greater occupancy rate than you actually have. The Minimum Energy Performance Calculator for NECB 2011 ACP is an excel based tool to be used when projects are documenting compliance using the NECB ACP for LEED v4 BD+C and LEED v4 ID+C EA Prerequisite Minimum Energy Performance and EA Credit Optimize Energy Performance. Is outdoor air quality testing required in a space using natural ventilation? Our expert advice guides our LEEDuser Premium members and saves you valuable time. List the factors that contribute to maintaining good indoor air quality (IAQ): 1. LEED 2009 projects may use ASHRAE 55-2010 or ASHRAE 55-2013 in lieu of ASHRAE 55-2004 for EQ Credit Thermal Comfort- Design. —Rp, People OA: The values are based on MET (Metabolic) Rate which is covered in ASHRAE 55. 3. Credit. Add 2 transient occupants to the transient occupancy & FTE for the regularly occupied areas for purposes for WE credit 2 & 3 calculations. Additionally, LEED Interpretation 2208 (CIR ruling dated 6/25/2008) referenced in the inquiry, is indicated within the LEED Interpretation database as NOT applicable to the LEED NCv2009 rating system.In regards to naturally ventilated kitchens, natural ventilation systems designed in accordance with Section 5.1 of the standard do not need to meet the mechanical ventilation (exhaust) requirements of Table 6-4. 1. The applicant is requesting a waiver from the ASHRAE 62.1-2007 Section 5.1 natural ventilation prescriptive requirements for three rooms within the existing building. The same standard must be used for both credits. The entire space will be air conditioned to maintain ASHRAE comfort levels. The greater the difference in EVs the more OA you have to provide for the system. For over 20 years, GrayWolf’s highly advanced, professional indoor air quality (IAQ) meters and instruments have made proactive IAQ and green building surveys efficient and easy to conduct.. Measure key specific pollutants (e.g. ... Natural Gas heating is reported in the Minimum Energy Performance Calculator Performance Outputs tab for the Baseline Option 1. EQ credit 7: Thermal Comfort, Compliance with ASHRAE 55-2004 (The data center will be designed to meet ASHRAE TC9.9 recommendations on Thermal Guidelines for Data Processing Environments.) However, these occupancy counts are provided for typical core and shell project types. For spaces or portions of spaces that are ventilated using mechanical ventilation or a combination of mechanical and natural ventilation, the documentation must show compliance with the ventilation rates indicated in Table 6-1 of ASHRAE 62.1-2007 (2004 for LEED-v2) and the Ventilation Rate Procedure calculations indicated in Section 6.2, using appropriate values for zone air distribution effectiveness (Ez. Table 6-4 of ASHRAE 62.1-2007 indicates 100 CFM of intermittent exhaust should be provided for residential kitchens. EQ credit 2: Increased Ventilation 4. 5. The same standard must be used for both credits. a combination of natural ventilation with mechanical exhaust, or some other means of assisting the outside airflow through the openings and circulating it through the occupiable space), the following expectations apply:Compliance when the local ventilation code governing the project is ASHRAE 62.1-2007 (or 2004 for LEED-v2 projects): We understand that many local jurisdictions would not be willing to provide confirmation that your engineered natural ventilation approach meets the intent of ASHRAE 62.1-2007. PREREQUISITE Minimum Indoor Air Quality Performance To contribute to the comfort and well-being of building occupants by establishing minimum standards for Indoor Air Quality (IAQ). Not a member yet? Hot tips to give you shortcuts and avoid pitfalls. Principal. That is why we need to find a rough equivalent that takes the reviewer's judgement out of consideration. Required. The planned factory will have 1000 sewing machines and few finishing equipments among others. The following is what I can share with you about how the ventilation tool should be used; with EVs and the critical zone data provided to the ventilation designer. Is "v2009v4_Minimum IAQ Performance Calculator_v03" spreadsheet is the correct/right one for a project registered in February 2016 in LEED 2009? Many health and healthy building advocates hoped they would lower the allowable levels of formaldehyde, but due to industry uproar that did not happen. The project is designed to have about 60% of the building footprint as future tenant occupied datacenter space with the rest as support offices, shipping & handling office, corridors, restrooms, mechanical and electrical rooms. They are not as different as lighting, but the two standards try to address what is not easy to analyze by having other requirements built into the standard in other places. LEED v4 for BD+C: New Construction and Major Renovation Project Checklist Y ? I am trying to use the "v2009v4_Minimum IAQ pERFORMANCE cALCULATOR_V03" to demostrate compliance with the Prerequisite, however, I does not calculate "Ev" nor it indicates the critical zone for the calculation.

The project’s performance data is collected on a rolling basis throughout the year, with the “current score” displayed based on the most recent 365 days. Required. — Look for the critical zone, and then look at the difference between EVs for all of the zones. These spaces should be excluded for three reasons, 1. Australia’s Equipment Energy Efficiency (E3) program involves a combination of pure Minimum Energy Performance Standards (MEPS), responsible for about 80 percent of savings, and labeling or labeling combined with MEPS, which delivers the other 20 percent of savings. The CIR is asking for verification that they have selected the appropriate Occupancy Category for their project, given that it does not fall precisely within the categories listed in ASHRAE 62.1-2004. Collecting this data allows individuals to be aware of and promptly fix any deviations in indoor quality metrics. Looking for a simplified solution for demonstrating compliance with Minimum Indoor Air Quality Performance in LEED v4/LEED 2009? A LEED v4.1 O+M beta certification is based on the performance of the project space for a specific 1 year time period (365 consecutive days). For mechanically ventilated kitchens, the exhaust rates listed in Table 6-4 of ASHRAE 62.1-2007 are by definition required to be discharged to outside the building (per Section 3 air, exhaust: air removed from a space and discharged to outside the building). The entry points for both the Daylight and Acoustic Performance credits are lowered to encourage more projects to consider daylight and acoustic performance during design. 19. LEEDuser is supported by our premium members, not by advertisers. It is simply the zone with the lowest Ev—there will always be one in any system. The term critical means the zone you need to focus on when adjusting ventilation rates. May we use a more current version of ASHRAE 62.1 and ASHRAE 55? The old ASHRAE tool door was closed. LEED v4. Breathing zone outdoor airflow (V. bz) and/or system outdoor air intake flow (V. ot) shall be determined in accordance with Sections 6.3.1 through 6.3.5. Note, the exhaust requirements of Table 6-4 were clarified by ASHRAE through addendum O, which states "...exhaust requirements apply to all zones and/or systems regardless of the method used to determine minimum outdoor airflow rates (Ventilation Rate Procedure, IAQ Procedure, or Natural Ventilation Procedure)." 6. 6.3 Indoor Air Quality (IAQ) Procedure. EQ Credit 6: Controllability of Systems, Thermal Comfort- Yes, non-regularly occupied spaces are not applicable to this credit. If the performance approach is used, the Indoor Air Quality (IAQ) exhaust fan system must be specified as an input to the compliance software, and that system type reported on the performance CF-1R. The ventilation works out to 2,000 cubic-feet per hour (10x10x10 x 2); which equals 33-1/3 CFM (2000/60 = ~33.3). Where I donated 3000 hours of my personal time to the USGBC to develop LEED I learned much of this from the experts who developed the standards. LEEDuser’s checklists walk you through the key action steps you need to earn a credit, including how to avoid common pitfalls and save money. Add the peak 2 datacenter occupants to the average transient occupancy & FTE for the regularly occupied areas for purposes of SS credit 4 calculations. LEED v4.1 requires projects adhere to a compliance pathway in ASHRAE 90.1-2016. • LEED v4 projects may still choose a washer from the qualifying product list, if available. Building performance, such as ventilation and infiltration rates, is highly variable and has a direct effect on indoor air quality. Contaminants or mixtures of concern for purposes of the design shall be identified. Applicable Internationally. For projects utilizing bathroom or other exhaust to negatively pressurize the unit to draw in excess ventilation air from the corridors, if the primary makeup air source for the unit exhaust is designed to be provided through the apartment entrance/vestibule, the project team should sufficiently demonstrate that the makeup air is outdoor air and not relief air (or previously "used" outside air) from other occupied spaces in the building and that the exhaust operates continuously. On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. We would also like to know if re-circulating hoods are acceptable for both mechanically ventilated and naturally ventilated apartments, since we may have both in our project. Also, Is there any updated "62MZCalc.xls" (Revised April, 2011) for 62.1 - 2007? 2. Use either the “separate residential and nonresidential densities” or the “combined density” values. Have the spreadsheet calculate the equivalent CFM/SF for all the spaces and you can more easily find a match. Well, I see that I now have 1200 thumbs up. Updated to reflect the January 11, 2019 LEED v4 Building Design and Construction Addenda NC, CS, Schools, Retail, Data Centers, Warehouses & … Registration is completed online under "Register a Project". © 2020 BuildingGreen, Inc. All rights reserved except where noted. & As per CIR Ruling 1/29/2008 (referred in LEED NC 2.2 for credit EQ 8.1) - We consider the datacenter space as a non-regularly occupied space. 4.4 MEPS and Labeling. Table 1a. Most people are unaware of how the ASHRAE tool works as a design tool. Performance Results calculator on the ENERGY STAR website to generate the values. EQ Credit 7: Thermal Comfort, Compliance with ASHRAE 55-2004 (The data center will be designed to meet ASHRAE TC9.9 recommendations on Thermal Guidelines for Data Processing Environments. Cost tips to assess what a credit will actually cost, and how to make it affordable. ", Replace the text with "Breathing zone is the region within an occupiedspace between 3 and 6 feet above the floor. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies. The "Minimum Ventilation Rates in Breathing Zone" is the title of Table 6.1 and the values in the table are what ASHRAE determined would provide the proper ventilation rate in the breathing zone by using a simplified calculation approach. What I will explain below is how Dennis intended to tool to be used—as I remember it from around 2003 until today; I have used the ASHRAE tool as a design tool when helping mechanical engineers and owners solve compliance with LEED issue—we have never added OA when a ventilation design did not comply with LEED; we simply moved air around between zones.. — Enter your design zone ventilation rates for a system. For example, if the distance from windows or openings is more than 25 feet, is there an exhaust air fan located at the furthest distance from the windows that is inducing the outdoor air to flow through the space; is that exhaust fan flow equivalent to the outside airflow that would be required for the space if the Ventilation Rate Procedure were used? Preserving the buildings also contributes to our sustainable design efforts, but it has resulted in an issue with the prerequisite for indoor air quality. The CFM per SF (what is used by ASHRAE 62.1 Table 6-1, Minimum Ventilation Rates in Breathing Zone) is 0.33 (33.3/100). ASHRAE Standard 62.1-2007 or Non-U.S. Out intent was to explain such things in LEED to help designers do a better, and more sustainable, job when designing a building. The floor are works out to 100 square feet. 6.3.1 Contaminant Sources. 2. A year ago that was over 12,000 thumbs up. The USGBC has turned what is supposed to be a ventilation design tool into a "LEED" compliance tool. Typically, we anticipate 1 technician for duration of 2 hours for 1 day, biweekly. Is there significant difference? In this case, the project team would be required to submit documentation showing that the intent of ASHRAE 62.1-2007 (2004 for LEED-v2) has been met with the project\'s engineered natural ventilation system. Table 6-2 in standard 62.1 include Ez values based on how well a ventilation supply delivers air into the breathing zone. It is also not allowed if combustion equipment (such as gas-operated forklifts) is operated in the space. Note: The indoor air quality procedure (defined in ASHRAE Standard 62.1–2016, Section 6.3) may not be used to comply with this prerequisite. For datacenter occupancy count: As per LEED CS Appendix, default occupancy for a datacenter space is not listed. (I was the vice-chair of EQ TAG when we first developed the prerequisite and credit for ventilation. Equivalent". 3. The occupation density is 20-25 persons per 1000 square feet. CEN Standards EN 15251: 2007 and EN 13779: 2007", Add a new Option title to read: "OPTION 1. Electric Vehicle Charging, 5%. After a project is saved, even if it is not registered and paid for, the registrant may see the project under "My Projects". Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both. For LEED points concerning regularly occupied spaces: As per CIR Ruling 1/29/2008 (referred in LEED NC 2.2 credit EQ 6.2) & ASHRAE 62.1 2004, page 4 - definition of occupied space: "An enclosed space intended for human activities, excluding those spaces intended primarily for other purposes, such as storage rooms and equipment rooms, that are only occupied occasionally and for short periods of time." You need to convert Rp in CFM/Person to an equivalent CFM/SF. 6.3.1 Contaminant Sources. This documentation must clearly identify how the natural ventilation requirements stipulated in ASHRAE 62.1-2007 (2004 for LEED-v2) Section 5.1 have not been met (e.g. It would be beneficial to the LEED reviewer if, included with the prerequisite submission, the applicant provides an explanation of their rationale for the selection. Compliance when the local ventilation code governing the project cannot be documented to be at least as stringent as ASHRAE 62.1-2007: If the documentation described above cannot be provided, then, for purposes of LEED Certification, USGBC/GBCI would serve as the Authority Having Jurisdiction [since the local code authority does not have jurisdiction over ASHRAE 62.1-2007 (2004 for LEED-v2) or a ventilation standard of equivalent stringency]. Robert Smith, in Energy Efficiency, 2013. Calculators to help assess credit compliance. 3. 6. Credit. We believe re-circulated hoods should be acceptable to meet the exhaust requirements based on ASHRAE 62.1-2007 section 5.17.3.2, but wanted to confirm since this is a prerequisite. If the total tenant occupancy count is not known, the Appendix 1 guidelines can be used. LEEDv4 IAQ Testing Summary.

Therefore recirculating hoods alone do not meet the exhaust requirements of Table 6-4 of the standard for mechanically ventilated kitchens. At peak we anticipate 2 technicians for the same duration. 2. The new window areas are insufficient to meet the prescriptive requirements and are specified and installed per university requirements. The main revision to MEP (Mechanical, Electric, Plumbing) credits is the updating of referenced standards. If you think you will do such equivalence often, it might make sense to make a spreadsheet out of ASHRAE 62.1 Table 6.1. Unfortunately, all of the above explanation is nowhere to be found in the ASHRAE standards which is what LEED Reference Guides do not mention any of it. IEQp1: Minimum Indoor Air Quality Performance Anticipated IEQc2: Increased Ventilation Anticipated 1 1 UCSD Telemedicine and PRIME-Heq (4036) Project ID: 1000003532 LEED for New Constructions LEED Certification Project Review Report July 02, 2012 2 of 14.

Prereq. — FYI: There will always be a critical zone in a ventilation system. Now, the likely reason that "other" is not (no longer) and option is that the GBCI/USGBC does not want their reviewers making judgement decisions if the "other" you have used is appropriate. performance approach. EQ credit 1: Outdoor Air Delivery Monitoring 3. Certification may be paid at time of registration. smaller operable window area, larger distance from operable windows or openings, etc.). Eagle One is the professional espresso coffee machine that becomes the center of the expression and personality of the coffee shop and the barista. EQ credit 8.1: Daylight & Views Is datacenter a non-regularly occupied space? After calculating the window ventilation areas, all but three of the rooms comply with ASHRAE 62.1 for natural ventilation. Y? The documentation required for EQp1 would include confirmation that all of the mandatory requirements of ASHRAE 62.1 have been met, a narrative describing the engineered ventilation modeling approach, evidence documenting that the plans have been approved by the local code authority, and some form of evidence that ASHRAE 62.1-2007 (or a later version of ASHRAE 62.1) is required for local building code compliance.Compliance when the local ventilation code governing the project can be documented to be at least as stringent as ASHRAE 62.1-2007 (or 2004 for LEED-v2 projects):If the local code requirements relative to ventilation are governed by an alternate code (any code other than ASHRAE 62.1-2007 (2004 for LEED-v2) or a later version of ASHRAE 62.1), then the project team must provide evidence that this alternate code is at least as stringent than ASHRAE 62.1-2007 (2004 for LEED-NCv2) in its entirety. You need to look at your design for your ASHRAE 170 spaces and find the best fit to model it using the ASHRAE 62.1 tool. 6.3 Indoor Air Quality (IAQ) Procedure.

Low values are for low activity (5 CFM/person is for most sitting). N; Credit. What I do when completing the LEED Form when I have a space where I am using a odd choice to provide an equivalent space type it to provide a brief explanation in the Special Circumstances text box. Premium members get: In the end, LEED is all about documentation. To establish minimum indoor air quality (IAQ) performance to enhance indoor air quality in buildings, thus contributing to the comfort and well-being of the occupants. USGBC has developed a Minimum Indoor Air Quality Performance calculator that can be used to demonstrate compliance with ASHRAE 62.1 in LEED BD+C, ID+C and O+M. Now I am trying to fill in the V2009v4_Minimum Indoor Air Calculator for multiple zone systems, because I have one system serving maybe two spaces under ASHRAE 170 or a mix of spaces, some under 170 and others under 62.1. I have tried explaining parts of the underlying basis of the ASHRAE standards as I learned them from real experts in the passed. But I think those comments are lost in time; they are hard to find of they are still around. Try it free », Mitchell Gulledge Engineering, Inc. We was primarily Steve Taylor and Dennis Stanke, with my developing the credit language for them in a way to get it included as part of LEED; a task harder than it have been. It also minimize the potential for reviewers to comment on use of an old version for compliance. And ASHRAE 62.1 is CFM-based. Add the following after the text for Case 2: Add the following language under Case 1: "Mechanical ventilation systems must be designed using the ventilation rate procedure as defined by ASHRAE 62.1-2007, or the applicable local code, whichever is more stringent.". They have 0.06, 0.12 and 0.18 (and one 0.48 space). Credit. Should I be using the one for 62.1 - 2010 though? Ideas for going beyond LEED with best practices. © Copyright U.S. Green Building Council, Inc. All rights reserved.

And, would the exclusion for the above points, be allowed? Based upon Appendix 1 of the LEED-CS Reference Guide, if the total tenant occupancy is known, this must be used for all calculations, as long as the gross square footage per employee is not greater than that in the default occupancy count. Option 1. The applicant is asking to exclude an area of the project, a datacenter that can be considered non-regularly occupied, from the calculations of various prerequisites and credits under LEED-CS. Our project is a mixed use facility with a combination of a high-rise (21-story) and mid-rise (6-story) residential apartment building. Without that information a designer cannot use the tool to improve a ventilation design. For this project, the proposed methodology is acceptable. The introduction of outside air into these spaces is problematic, and 3. The storage areas are intended for storage of frozen goods and are uninhabitable environments, only occupied occasionally and for short periods of time, as dictated by OSHA requirements.
