WIMSEE extended

WIMSEE is a great chart that is referenced a lot as a way to remember the numbers of prerequisites and available point in each LEED NC section. I put it up a while ago in a post about InTheLEED.com, a great study resource.

I am making some adjustments to it to help me remember the ID opportunities and submittal phases of as well. They are not in beautiful ascending order as the rest of WIMSEE is, but when they are added to the table it makes a fairly simple visual for me to remember.

Please note that people have mentioned some discrepancies between people’s ID counts – especially in the SS section. I think this is due to the Alternative Transportation credits. I arrived at my seven by counting: SS2 – you can double the density of the project itself or you can double the base credit area and corresponding density; SS4s – alternative transportation management plan; SS4.1 – increase threshold of distances to public transportation and require high frequency of service; SS5.1 – increase threshold to 75%; SS5.2 – double everything; SS7.1 – 100% high-albedo surfaces or underground parking; SS7.2 – full green roof. Pat on InTheLEED counted all the Alt Trans credits as one. I believe, however, that two points are available. Someone please correct me if I am wrong. (Thank you reader ‘brandon’ for bring this to my attention in the comments).

Anyway, here it is:

WIMSEE extended

So then I use a little rhyming to remember the numbers…

206723: the order of id points available in WIMSEE.
Plenty (20) of tricks (6) can get you into Heaven (7). But you won’t be true (2) and free (3).

For the submittal phases, I do a more visual approach. I fill in all the ‘designs’ and ‘constructions’ which is fairly easy once you try it a couple times.

Then for the numbers, I put in all the p1’s first. Then I put anything with a .1 after it. Then 3,5,6. In the end I treat it like a series of steps. And I only have to remember a couple numbers for each step, so it’s not so bad. Hope this works for someone else too!

standards using the ‘G’ word

They’re addicted to this word. They all use it in varying forms with little unrememberable prefixes and suffixes that contribute to the green haze surrounding all environmental standards. Let’s try to clear some of this up.

Green Seal
Green Label
Green Label Plus
Green-e products
Green Score

you got any more? I can add them on.

Ok, we already covered Green Seal in the previous post. But we need a way of distinguishing these other ‘greens’ from each other.

Green Label – I visualize the label on the back of a rug or carpet sample when you go to Home Depot or something. And the Label is on the back of the carpet, where it meets up with the cushion. Green Label sets VOC limits for carpet cushions, as applicable in EQ 4.3: Low-Emitting Materials – Carpet Systems.

Green Label Plus – Well, ‘plus’ sounds a bit like ‘plush’, which helps you remember that we’re talking about carpets (because they always sell their carpet as being ‘plush’). Green Label Plus sets VOC limits for carpets, as applicable in EQ 4.3: Low-Emitting Materials – Carpet Systems.

Green-e products – Well, if the questions uses the word ‘products’, you’re fine because this is the only one that applies to electrical products. But it probably won’t – it will probably be talking about renewable energy of some sort. You just have to be sure to remember that this applies to GREEN POWER not on-site renewable energy. You can remember by thinking that the suffix ‘e’ kinda is used like the prefix ‘e’ on email. Something Electronic that is traded back and forth, as in credit EA 6: Green Power.

Green Score – The word ‘score’ makes me think there’s some kind of contest of race. What do people like to race? Their cars. A Green Score of 40 points is necessary to qualify a vehicle for credit SS 4.3: Alternative Transportation – Low-Emission and Fuel-Efficient Vehicles.

ASHRAE standards

Ok… I hate these things. But I WILL memorize them.
For this, I am going to use the rhyming numbers method (combined with a couple keywords here and there… you’ll see).

to remember that:
ASHRAE 52.2 is about filtration media (MERV) and correlates to credits EQ 3.1 and EQ 5,
I will first assign rhyming words to relevant numbers:
5-hive; 2-blue; 3-bee; 1-run; 5-dive
now I create a visualization with these words…
There’s a hive (5), with a blue (2) sky behind it. There’s a guy named Mervin (MERV filters). He sees a bee (3)!!! First he tries to run (1), but then eventually he has to dive (5) into the ocean to escape.
and this is roughly what I see…

Now the other ASHRAE standards. I won’t get into the image assembly for these, so you will have to use your imagination!

ASHRAE 55 – thermal comfort – EQ 6.2 and EQ 7s
We’re with our friend again and there is still a hive (5). Again he has to dive (5). But this time it’s not so comfortable (Thermal Comfort). He accidentally hits some sticks (6) on his way down and loses a shoe (2). But don’t worry; he goes to heaven (7s).

ASHRAE 62 – ventilation – EQ p1, EQ 2, and EQ 6.2
There are some bricks (6) in a pile. Next to them is some glue (2). Some crazy person is building a wall in front of the vents (ventilation) in his office. When asked why he is doing it, he replies that he has to (required- prerequisite) and that he is not just doing it for fun (1). The other people in the office are so mad that one woman throws her shoe (2) at him. The other employees steel away the bricks (6) and glue (2).

ASHRAE 90 – energy and lighting – SS 8, EA p2, EA 1
There’s a glass of wine (9) next to the bed (0-zed). There’s a woman with no energy to get up and turn off the light (energy and lighting). She demands (pre-requisite) that her boyfriend do it instead. He also doesn’t want to get up, so he throws his shoe (2). Then he says, ‘That was fun (1)’!

p.s. – Added by Allison to ASHRAE 90 – “So they sleep soundly (SS) for 8 hours.” (Thanks, Allison!)

Please excuse all the shoe-throwing references, but Bush rarely gets mentioned these days.

3. How do you earn the ID credit for this?

answers:

1. ‘78, got a date. 2:12, we stick like glue. 29, now he’s mine.’ This little rhyme helps me remember the numbers in order, with 78 SRI applying to low-sloped roofs, 2:12 being the determining slope, above which – SRI 29 applies.

2. Either the SRI for 75% of the roof has to meet the 78/2:12/29 criteria OR you have a 100% green roof OR you do a combo of these two strategies where the total roof area = (area of SRI roof × 75%) + (area of green roof × 50%)

possible questions for SS 6.2

possible questions for SS 6.2:

1. What strategies could help remove pollutants from stormwater?

2. It’s possible to reuse stormwater for non-potable water purposes such as what?

3. What’s the most effective way to reduce stormwater runoff volume and treatment?

4. What should BMP’s (Best Management Practices) include to ensure that 80% of TSS are treated in post-development?

5. Where pervious pavement is employed what information is required for the submittal?

answers:

1. Non-Structural ‘SwaDis Perv’: ❶ vegetated swales ❷ disconnection of impervious areas ❸ pervious pavement. Structural ‘RainMan Pond’: ❶ rainwater cisterns ❷ manhole treatment devices ❸ ponds

2. Landscape irrigation, fire suppression, toilet and urinal flushing, and custodial uses.

3. Minimize the amount of impervious area. Strategies included in SS 6.1 – ‘Harvest your veggies before the pervious roofing causes clusters of ponds at your feet!’.

4. BMP’s are considered to meet the criteria if… ❶ they are designed in accordance with standards or specifications from a state or local program that has adopted these performance standards ❷ there exists in-field performance monitoring data demonstrating compliance with the criteria. Data must conform to accepted protocol, e.g. TARP). Just remember, they always want standard and verification.

Submit a list of BMPs, including a description of each BMP and the percent annual rainfall treated.

possible questions for SS 6.1

possible questions for SS 6.1:

1. They could give you an example project with an existing imperviousness greater than 50%, and then give you the runoff rate and quantity from before the development. Then the question would be to calculate the post-development runoff rate and quantity to qualify for SS 6.1.
Example A: A project site has an existing imperviousness of 80%. The pre-development runoff rate is 100 cfs and the pre-development runoff quantity is 10,000 cf. What must the post-development runoff rate and quantity be to earn SS 6.1?

2. What strategies could help mitigate a site impervious area?

3. It’s possible to reuse stormwater for non-potable water purposes such as what?

4. In a project with an existing imperviousness less than 50%, and what is required in order to earn this credit?

5. A project team wishes to use pressurization in order to harvest rainwater for irrigation. What other items must be addressed by the team based on adding this feature?

6. What records must be submitted for this credit?

answers:

1. The requirements of Option 2 of this credit say that the post-development rate and quantity must be 25% less than the pre-development values to earn this credit. We can remember the requirements of Option 2 by the simple math equation: 50 / 2 = 25 (over 50% is option 2, which requires 25% less runoff).
Example A: The post-development runoff rate must be under 75 cfs, and the post-development runoff quantity must be under 7,500 cf.

2. ‘Harvest your veggies before the pervious roofing causes clusters of ponds at your feet’. ❶ stormwater harvesting ❷ vegetated filter strips or bioswales ❸ pervious paving materials ❹ green roofs ❺ clustering development ❻ retention ponds ❼ smaller building footprint

3. Landscape irrigation, fire suppression, toilet and urinal flushing, and custodial uses.

4. Create a stormwater management plan that prevent the post-development runoff rate and quantity from exceeding the pre-devlopment values for 1-yr, 2-yr, and 24-hr design storm OR implement a stream channel protection strategy and quantity control strategy. Remember a math equation similar to the one for Option 2… (50 / 1 = 50), where in projects with lest than 50% imperviousness, following the requirements of Option 1, you must maintain  or better the same value.

5. Commissioning of the system, because a pump for the pressurization will consume energy and anything consuming energy must be commissioned. And the conveyance system to keep the rainwater from being connected to potable water. For questions like this, as well as synergy questions, you can go through a small checklist of things to consider when capturing and reusing stormwater runoff. ‘WDD.CPP’ ❶ water need ❷ drawdown ❸ drainage area ❹ conveyance system ❺ pretreatment ❻ pressurization. And of course commissioning is just an extra you should always think about.

6. Pre and post development runoff rates and quantities and a narrative describing project conditions, measures taken, and controls installed.

possible questions for ss 5.2

possible questions for ss 5.2:

1. Given a local zoning requirement and the size of a project, how many total acres of open space must the project contain to qualify for this credit?
Example A: On a 20 acre project, local zoning requires 4 acres of open space. How many total acres of open space must the project contain to qualify for this credit?

2. If an area has no local zoning requirements, how would a project achieve this credit (for example military bases, and some college campuses)?

3. What are some methods or strategies for increasing the amount of open space?

4. If a project has received credit for SS 2, and is attempting to achieve this credit as well, what allowances does it get?

5. Do wetlands count as open space?

6. How do you achieve the ID credit?

answers:

1. Where a local zoning requirement exists, you must exceed it by 25%. I remember the 3 options with a dimension – 25’20. 25% reduction on any existing zoning requirements; foot = area of building footprint for places with no zoning; and 20% of site for places with incomplete zoning.
Example A: In this case, instead of 4 acres, you would be required to reserve 5 acres as open space to get the credit.

2. Maintain open space equal to the building footprint. Use 25’20 again to remember options.

3. site the building to minimize disruption to ecosystems, install a vegetated roof, share facilities, install pedestrian hardscape.

4. vegetated roof areas can contribute to calculation AND pedestrian-oriented hardscape areas can contribute (as long as 25% of the open space is vegetated).

5. Wetlands only count as open space if the side slope gradients average 1:4 (vert:horiz) or less and are vegetated.

6. double the amount of open space required. so instead of 25’20, you would have 502’40 where: in option 1, you must exceed zoning requirements by 50%; in option 2, you must double the building footprint; and in option 3, you must provide open space 40% of site area.

possible questions for ss 5.1

possible questions for ss 5.1:

1. What are the various site disturbance limits for this credit?

2. What is included in the definition of the ‘building footprint’?

3. What strategies should be used to limit site disturbance?

4. Given an example previously developed site, how much of the site area needs to be protected or have vegetation restored to qualify for this credit?
Example A: A 1,500,000 sq.ft. previously developed site has a building footprint of 500,000 sq.ft. How much of the site needs to be be protected or restored?

5. How can you earn the ID credit?

6. If a project has already earned SS 2 credit, what are its special allowances concerning this credit?

7. Can a project with a zero lot-line on a greenfield site still earn this credit?

answers:

1. 40 feet beyond building perimeter; 10 feet beyond surface walkways, patios, surface parking and utilities less than 12 inches in diameter; 15 feet beyond primary roadway curbs and main utility branch trenches; and 25 feet beyond constructed areas with permeable surfaces. Lots of numbers to remember here; helps me to think of the visual with the zeros on the ends and the 5s in the middle. Then use – ‘10,15,25,40: Walk down the road to permeate the perimeter’ – to remember the limits.

2. The ‘building footprint’, as defined by the reference book, is “the area on a project site that is used by the building structure and is defined by the perimeter of the building plan. Parking lots, landscapes and other non-building facilities are not included in the building footprint”.

3. ‘suscup’ strategies: ❶ Stacking development ❷ Underground parking ❸ Share facilities ❹ mark Clear construction boundaries ❺ Utilize plant experts ❻ Prohibit invasive plants

4. For previously developed sites, 50% of the area of the site (excluding the building footprint) must be protected or restored (*see 6 below).
Example A: the answer is 500,000 sq.ft.

5. Only if it is on a previously developed or graded site, you can earn the ID credit by protecting or restoring 75% of the site (excluding the building footprint).

6. If a project has earned SS 2, then a vegetated roof surface may apply to the calculation. In this case 20% of the site area needs to be covered with native plants (as opposed to 50%).

7. no

possible questions for SS 4.4

possible questions for SS 4.4:

1. What qualifies as ‘preferred parking’?

2. What are the 4 options for achieving this credit?

3. In a project where no local zoning requirements exist, how would you calculate the number of parking spaces needed to achieve this credit?

answers:

1. ‘Preferred Parking’ is defined in the reference book as “parking spots that are closest to the main entrance of the project, exculsive of spaces designated for handicapped, OR parking passes provided at a discounted rate”.

2. All you need to remember is that there are 4 options and you should always do the least possible with 5% preferred parking reserved.
❶ do not exceed minimum local zoning requirements for parking AND provide preferred parking for 5% of total (carpools) – non-residential only
❷ if the project provides parking for less than 5% FTE, provide preferred parking for 5% of total (carpools) – non-residential only
❸ do not exceed minimum local zoning requirements for parking AND provide infrstructure and support for carpooling – residential only
❹ no new parking

3. Under the requirements of Option 2, where no local zoning exists, the project must provide parking for less than 5% of the FTE occupants, with 5% of those spaces being reserved for ‘preferred parking’. Always calculate the FTE for the largest shift of a series of non-overlapping shifts.

possible questions for SS 4.3

possible questions for SS 4.3:

1. What are the three compliance paths for this credit?

2. In order for a fuel-efficient vehicle to be valid in contributing to Option 1 of this credit, what standard must it meet?

answers:

1.❶ provide low-emission and fuel-efficient vehicles for 3% of FTE occupants AND preferred parking for them ❷ provide preferred parking for low-emission and fuel-efficient vehicles for 5% total parking capacity ❸ install alternative fuel refueling stations for 3% total vehicle parking capacity
So, in short, cars for 3% FTE, preferred parking for 5% total, stations for 3% total. Remember it in order by chanting – ‘353 FTE’. That helps you remember the order of the percentages, and the fact that it starts with the figure as a portion of FTE occupants. For the 5 and 3 at the end, you know it’s between preferred parking and alternative refueling stations. Clearly it makes sense that it’s easier to assign the higher percentage -5- to preferred parking and 3 to stations.

2. A Green Score of 40 or more OR Zero Emission Vehicle as determined by the California Air Resources Board.

possible questions for SS 4.2

possible questions for SS 4.2

1. Given the building type and number of Full Time Equivalent Occupants, how many showers are required?
Example A: A commercial building has 1500 FTE occupants. How many showers are required to earn SS 4.2?

2. Given the building type and number of building occupants, how many secure bicycle storage spaces are required?
Example B: A 5-story condominium project has an estimated 2000 building occupants. How many bike storage spaces are required to earn SS 4.2?

3. Given the building type and the number of full-time and part-time occupants, how many showers are required?
Example C: An office building with 180 full-time employees and 40 part-time employees (at 20 hours per week) has 30 peak period visitors per day.

4. If a project choses to use shared showering and changing facilities, how close to the building entrance do they need to be?

answers

1. I personally hate TV… mainly because I hate the ads. First, we need to remember that the option for commercial buildings in this credit requires that 5% of all building users (at peak) must have a place to store their bikes. Then, by remembering our funny phrase, ‘commercials are smelly’, only 0.5% of the FTE occupants actually take a shower once they arrive. So you just have to remember the number 5 at two different orders of magnitude.
Example A: Since 0.5% of 1500 FTE occupants is 7.5, and we can’t have 7.5 showers… we round up to 8.

2. For residential buildings (which are far less smelly), 15% or more of the building occupants must have bike storage spaces.
Example B: 300 spaces required.

3. Calculate the FTE occupants using the formula below, and then calculate 0.5% of that many occupants.
Example C:
180 full-timers (180 × 8 hours/day) = 1440 manhours ÷ 8 hour workday = 180 FTEs
40 part-timers (40 × 4 hours/day) = 160 manhours ÷ 8 hour workday = 20 FTEs
so, 200 FTEs × 0.5% = 1
peak period visitors do no count.

4. 200 yards.

possible questions for SS 4.1

possible questions for SS 4.1:

1. What are the 2 compliance paths for this credit?

2. How close does a building’s entrance need to be to a rail or bus line?

3. How can you earn the ID credit for the Alternative Transportation Credits 4.1-4.4?

4. What documents should be submitted for this credit?

5. If a project is located more than the minimum distance from a bus or rail line, is there a way to still achieve this credit?

answers:

1. Develop within ½ mile of a commuter rail, light rail, or subway station OR develop within ¼ mile of  ≥ 1 stop for ≥ 2 public or campus bus lines. You can remember this with the math equations, (rail = stop × 2 bus lines) and (½ = ¼ × 1 × 2).

2. Remembering our equation (½ = ¼ × 1 × 2), ½ from a rail line OR ¼ from at least 1 stop on at least 2 bus lines.

3. By instituting a transportation management plan that quantifiably reduces auto use.

4. Vicinity drawing showing site location and rail or bus lines.

5. Yes, provide shuttle buses to the public transportation.

possible questions for SS 3

possible questions for SS 3:

1. What standard can be used to document that a site is contaminated?

answers:

1. ASTM E1903-97 Phase II Environmental Site Assessment, a local VCP (Voluntary Cleanup Program), or a local/state/federal designation as brownfield. Remember the numbers of the ASTM by thinking that 1903 to 1997 is almost a century; it is shy 3 years on each end and 3 is the number of possible documentation routes to obtain this credit.

possible questions for SS 2

possible questions for SS 2

1. Straight up question – what are the two options for meeting the requirements of SS 2?

2. What is included in the development density calculation?

3. What is a density radius calculation used for?

4. How many times can services be counted?

5. What documentation is required for this credit?

6. How do you earn exemplary performance for this credit?

answers

1. Remember the principles of the options from the name of the credit: The first option is  the density of where you chose to develop; the second option is the connection to community services. Another thing that may help is just reciting the numbers – 60,000 and (½ of 5). 60,000 is the minimum development density in sq.ft. per acre for Option 1. And  (½ of 5) doubles for both requirements of Option 2 – within ½ mile of a residential zone with at least 10 units per acres AND within ½ mile of 10 basic services. Remember, always on a previously developed site.

2. According to the reference guide, “both the project density and the densities of surrounding developments must be considered… Include all properties in the density calculations except for undeveloped public areas such as parks and water bodies. Do not include public roads and right-of-way areas.”

3. to define the properties included in the development density calculation

4. All services can only be counted once, except restaurants which may be counted twice.

5. gross building area and project site area

6. must meet one of the following: ❶ project has a density double that of avg density in calculated area ❷ avg density in area twice as large is at least 120,000 sq.ft per acre
