RETIRED LEEDuser Expert 623 thumbs up April 28, 2014- 4:23 pm Nouran- Typically you'll have different manufacturers and sustainable criteria for components and hence need to enter items on separate lines to utilize the BDC Material and Resource Calculator. But if you are not utilizing sustainable criteria for furniture, I guess you could put it all on one line but they why would you include...

Very confused- Natural Ventilation

NC-2009 IEQc2: Increased Ventilation
posted by Jeff Potter on May 5, 2014, 11:42 am

Tony Ricketts Mechanical Engineer CJL Engineering LEEDuser Basic Member 25 thumbs up May 6, 2014- 8:45 am Jeff, I did a Preschool / Daycare NC project between Philly and Allentown with a similar situation, and our Increased Ventilation credit was rejected. I'm going from memory here, but their explanation was something along the lines of 'a project cannot utilize both natural and mechanical ventilation to meet the requirements of this credit. There is no need for the air conditioning system to be operational while windows are open and the space is being naturally conditioned, as this would cause...

correction for online reference guide

NC-v4 SSc4: Rainwater management
posted by Lyle Axelarris on May 8, 2014, 9:55 pm

I have subscribed to access for the online v4 Reference Guide, and I noticed a couple of mistakes in the example for this credit. I'm not sure how to provide feedback to USGBC regarding this, so I thought I'd try posting it here. In the Examples section, the Horton's equation is given as: Ft = fmin + (fmax – fmin) e- k t The "-kt" term is an exponent of 'e', but that does not come out clearly with single-line text. I suggest typing it as: Ft = fmin + (fmax – fmin) e^- k t The "^" is standard notation for an exponent in single line text. Also, the weighted...

Parking split for different tenants

CS-2009 SSc4.4: Alternative transportation - parking capacity
posted by Renaud Gay on May 26, 2014, 11:13 pm

I can't be certain it will pass, but it seems a reasonable approach. Along those lines, I think you can divide the spaces up per tenant if each tenant has specific assigned parking spaces. If it is general...

Parking Capacity includes capacity for Future Development

NC-2009 SSc4.4: Alternative transportation - parking capacity
posted by Sadie Martin on Jun 2, 2014, 12:53 pm

We are working on a project that is trying to jumpstart development in the city center. Our project is providing more parking then needed by the building so that future buildings nearby can tie into the parking garage instead of creating new surface lots. Has anyone had success with arguing for a case like this? If we receive a signed letter of intent from these future devopements saying that they will be tieing into this parking garage, could we only count the spaces that will be reserved for our building within our LEED documentation even though the entire garage is within our boundary? SSc4.4 ...
