re: vegetated roofs, the bad synergy is the significant load that soil imposes (if used) which will increase structural requirements such as amount of steel.

(glad I could contribute 2 cents worth that has not already been superbly covered on this site)

re: Parker’s mention of, and link to, the USGBC Technical Manual. Thanks for the link. I was able to download, though I don’t think I’m a USGBC “member” as I don’t work for a member company – which is a lousy arrangement if USGBC is really trying to disseminate info to help people understand good environmental practices.

which gets to my sincere thanks to Pat and this website –> it is definitely the BEST resource – and in the spirit of helping the environment, it’s terrific that this info here is free, rather than throwing up yet another expensive roadblock to doing the right thing.

Cheers to you.

I dumped that link in lieu of http://www.sla-bangkok.com, and my study forums got axed.

Here is what I have so far:

Synergy A—>B also means B—->A. Please understand that in some cases I just described A—–>B which was already a lot of work.

(! means MAJOR CREDIT SYNERGY)
(* means COMPLEX CREDIT SYNERGY)

- SSp1 with SSc5 and SSc6!
- SSc1 with SSc2 and SSc4 (and more)
- SSc2 with SSc1, SSc4’s, SSc8 (and more)
- SSc5.1 with SSc6!, SSc7!, WEc1! (and more)
- SSc5.2 with SSc5.1!, SSc6!, WEc1! (and more)
- SSc6.1 with SSp1!, SSc5!, SSc7!, WE’s! (and more)
- SSc6.2 with SSp1!, SSc5!, SSc7!, WE’s! (and more)
- SSc7.1 with SSc5, SSc6 and EAc1
- SSc7.2 with SSc6!, WE’s!, EAc1! (and more)
- SSc8 with EAp2, EAc1(op.1)! and EAc2
- WEc1 with SSc5, SSc6, SSc7, WE’s (and more)
- WEc2 with SSc6, WEc3 (and more)
- WEc3 with SSc6, WEc2 (and more)
- EAc2 with EAp2, EAc1(op.1)! and SSc8
- EAc5 with EAc1,EAp1 and EAc3
- EAc6 with EAc1 and EAc2
- MRc1 with MRc2*
- MRc2 with MRc1*
- MRc3 with MRc5
- MRc5 with MRc3
- MRc7 with IEQc4.4
- IEQc1 with EAp1, EAc1, EAc3, IEQp1, IEQc2 and IEQc6.2
- IEQc2 with EAp1*, EAc1*, EAc3*, IEQp1, IEQc2 and IEQc6.2
- IEQc3.1 with EAp1, EAc3, IEQc5
- IEQc3.2 with IEQp1, IEQc3.1, IEQc4’sand IEQc5
- IEQc5 with IEQc3, IEQp1, IEQc2 and IEQc6.2
- IEQc6.1 with EAc1*
- IEQc6.2 with EAc1*, IEQc7.1* and IEQc7.2*
- IEQc7.1 with EAc1 and IEQc6.2
- IEQc7.2 with EAc1, IEQc6.2 and IEQc7.1

We could work later on a revised list that will include:
Synergy A—>B AND B—->A for the picky ones.

Hope this helps!

Are there any more synergy examples available elsewhere on this site or anywhere else?

I’m sorry to say that there has not yet been a list of the ASTM standards for the NC Exam on this website. It’s a good idea though, so here it is for you:

ASTM E1903 “Phase II Environmental Site Assessment.” (SSc3)

ASTM C1371-04 “Standard Test Method for Determination of Emittance of Materials Near Room Temperature Using Portable Emissometers.” (SSc7.2)

ASTM C1549-04 “Standard Test Method for Determination of Solar Reflectance Near Ambient Temperature Using a Portable Solar Reflectometer.” (SSc7.2)

ASTM E408-71 “Standard Test Methods for Total Normal Emittance of Surfaces Using Inspection Meter Techniques.” (SSc7.2)

ASTM E903-96 “Standard Test Method for Solar Absorptance, Reflectance and Transmittance of Materials Using Integrated Spheres.” (SSc7.2)

ASTM E1918-97 “Standard Test Method for Measuring Solar Reflectance of Horizontal and Low-Sloped Surfaces in the Field.” (SSc7.2)

ASTM E1980-01 “Standard Practice for Calculating Solar Refletance of Horizontal and Low-Sloped Opaque Surfaces.” (SSc7.2)

ANSI/ASTM E779-03 “Standard Test Method for Determining Air Leakage Rate by Fan Pressurization.” (EQp2)

NOTE: you don’t necessarily have to waste your time with memorizing all of the crazy names for each of these, as far as the exam is concerned. Just know which ones go with which credit.

I hope this helps, and thanks – I’m sure others will find this useful too.

Good luck and let me know if you have any more questions. Cheers!

Here are the reasons why I believe the statements are not entirely correct.

In cold climates (like Minnesota)snow fall on an existing pervious parking area usually disappears on its own before snow on the adjacent, darker colored, impervious suface. Manual snow removal from this pervious surface has seldom been necessary.

If pervious paving systems are installed properly, snow plows will not damage them (if operated properly). Proper operation includes installation of skids or wheels on the shovel to keep it lifted slightly off of the paver surface.

If bad drainage occurs around a pervious surface, then the pervious surface location was a bad choice (someone didn’t do a proper site analysis), the paver bed was improperly prepared, or runoff from an adjacent area is being improperly directed to the pervious surface. Runon to a pervious surface should never be allowed unless it is a deliberate part of the drainage design (which for most pervious systems is NOT the case). Additionally, siltation also should not occur if the pervious system was properly designed and on-site conditions remain consistent with the design conditions. Most pervious systems seldom need vacuuming, even after years of operation – again, so long as runon is not allowed and the pervious system has ben properly installed in an appropropriate location.

Just my 2 cents. Obviously we are being tested on what the LEED study materials say. Hopefully these types of discrepancies will be cleared up over time as we all become more familiar with sustainable design practices and materials.

I just found out that you commented on Our Green Journey a few days ago — thanks! I am going to be studying for my LEED AP, so this blog will definitely be of great help. Keep up the great work!
