Mara Baum Partner, Architecture & Sustainability DIALOG LEEDuser Premium Member 674 thumbs up August 30, 2010- 7:35 pm Energy modeling of green roofs is pretty complicated business. A lot of the conventional energy saving strategies for roofs-- e.g. insulation values-- don't adequately address the real energy benefits of the green roof. In other words, it's not really about insulation....

Mara Baum Partner, Architecture & Sustainability DIALOG LEEDuser Premium Member 674 thumbs up September 8, 2010- 11:55 am Great question. I don't think the troop transport buses would be eligible for this, because they're not open to all building users. The closest example I have found in LEED CIRs is that of an island-- you should take a look at the CIR ruling for v2.2 posted 7/13/2009. Your project might (?) qualify for this circumstance if the base is limited access and the one public bus line connects people to a larger transportation network. This seems like a little bit...

Question on LEED NC 2009 SSc8- For Option #1 on the interior lighting portion, is having an occupancy sensor alone installed on fixtures that have a direct line of sight sufficient to meet this requirement? The credit states the the fixtures need to be reduced by 50%, which is easily attainable by an occupancy sensor that cuts them by 100%. It also states they need to be off from 11pm-5am and if manually over-ridden, turn back off in less than 30 minutes. It would seem that if the time delay on the sensors was set to 30 minutes this would satisfy the requirement, however the 30 minute time limit...

The site boundary of our building is lined with quite tall and dense trees. Should these be incorporated into the footcandle calculations? If the trunk of the tree is inside the boundary (but the leaves are both outside and inside) and the tree prevents light leakage at vertical plane on site boundary, we believe that they should be. However, typical calculation software cannot model trees. Has anyone had any experience with this? Thanks. SSc8 ...

its a matter of survival and China in that respects seems to be a lot more aware of this than others in the west would believe. What we are doing is just making buildings a little less unsustainble...

Collection from LEED Buildings.Bottom line: you should be aware of the reporting requirements, and buildings could lose their certification if they don't make a good-faith effort to comply with that....

In performing the initial analysis of the Energy Star score for our building it has become apparent we are teetering on the line of a 69. Is it required to hold an Energy Star score of 69+ for an entire 12 month period before certification or can the score dip below 69 for a month and still go through certification if it holds a 69+ at the time (not having a year straight of 69+)? EAp2 ...

Implementing LEED requirements during construction is a balancing act: provide too little information, guidance, or follow-up and some things will fall between the cracks, but if you provide too much, the GC and subs can get overwhelmed, annoyed, tune out, or waste a lot of time. This problem is not unique to LEED- for large commercial projects the amount of information that goes into a set of construction documents, especially the specifications manual is mind boggling. And what is not said, but assumed to be "standard practice" could fill even more volumes. The quantity and location...

Ryan Gaylord Director CTG Energetics, Inc. LEEDuser Basic Member 49 thumbs up September 2, 2010- 1:04 pm Since there are special conditions that govern the parking allocations for your project, I would suggest submitting a narrative along with your credit documentation explaining the limitations for parking in the smaller lot closer to the building. If you simply cannot fit all of the required preferred spaces in this lot, it seems reasonable that these spaces could be located in the structure. As you suggested, the spaces in the structure would need to be located either on the ground level,...

Tristan Roberts Representative Vermont House of Representatives LEEDuser Expert 11477 thumbs up September 2, 2010- 5:47 am From your description, it sounds like the total resulting coverage would be 8' wide (for a 6' door) and 12' long in the line of traffic. Is that right? Sounds good to me in terms of the credit requirements.Be sure to address the indoor/outdoor issue that's been discussed in other threads here. Log in or register to post comments ...
