A project I am working on meets all the requirements for the design (no cooling tower, no use of the latent heat of the evaporative cooling of water, no cooling from a District cooling system). There are a few core and shell spaces that, although there is no cooling tower in the design, the proposed energy model shows that a cooling tower serves these shell spaces in order to model them as neutral in the proposed and baseline energy model.

The intent of this credit is met as there is no cooling tower but technically the proposed energy model shows some cooling from a cooling tower as a technical work-around so that no energy savings can be gained from these spaces. Does anyone have thoughts on if this will affect the compliance of this credit?

LEED requirement says that Lighting for any presentation or projection wall must be separately controlled. Our project have small multiple meeting room where hanging on the wall TVs are used for presentation. As meeting room are small (4-6 person capacity), the engineer don't plan to design separate control for presentation wall. Besides, as presentation tool is a TV, lighting adjustment can be made on the TV to optimise visibility of the screen while occupants have enough light to take notes. Is it essential to have Lighting control for presentation wall? Tks

Hello,

The LEED v4 NC Schools guide stipulates that dishwashers must be Energy Star certified as well consume less than 6.0 liters/rack. For dishwashers with multiple programs or modes, does the consumption requirement need to meet the dishwasher's automatic setting or the heaviest consumption setting?

As an example, if dishwasher has a setting for heavily soiled items, does that need still need meet the <6 litres/rack? =

Thank you in advance!

Hello,

Regarding the "Signage Program" option for the Green Building Education innovation credit, I was wondering if it would acceptable displaying the project's sustainable features and achievements through a number of TV screens permanently installed in several locations of the project site. 

Thank you for your attention.

Kindest regards,

We have a project on a university campus that uses pooled parking. The project boundary is relatively tight to the building and we have figured out the share of this building's parking stalls based on area of the building vs. total building area on campus. 

How do we achieve this credit? I have seen the question regarding off-site parking and understand that we have to include them in the calculation. Is the parking area just the area of a standard stall multiplied by the 42 spots that are the project's share? Do we plant shade trees in a portion of the parking area?
 

Hi everyone,

We have a student housing project that is located within a university campus which has shared parking with the rest of the campus. There are some existing EV charging stations on campus. 

1. EVSE do not have location requirements.

a. Can we use existing EV charging stations (which meet the technical requirements and not already designated to a LEED project) towards the credit? If we do this, will the spaces be reserved for the building occupant's use only, even if it is far away from the building?

b. If we provide new EVSE charging stations, do they have to be located near the project building? 

2. Page 56 of the reference guide under "Total Vehicle Parking Capacity" states, "if parking spaces are shared among two or more buildings ("pooled" parking"), determine the share of this parking allocated to the project. Include this number of spaces in the total parking capacity and provide rational for the parking distribution if necessary." 

What is an acceptable way to determine the share of parking allocated to the project?

a. Do I ask the owner to guess and provide a narrative explaining rational?

b. (project building area / total campus building area) x total no. campus parking spaces

c. (project occupancy/ total campus occupancy) x total no. campus parking spaces

d. other?

3. Do preferred parking spaces, EVSE , (and carpool spaces) have to be reserved for use by the project building occupant's use only? 

thank you for your time!

I was wondering if anyone can shed some light on whether it would be acceptable to conduct a Design Charrette over the course of 4 days, as opposed to a 4 hour charrette in one day? Of course, we would comply with the 4 hour minimum charrette and have all of the stakeholders attending each of the meetings.

I would really appreciate a response.

Thank you,

With the LEED Canada 2009 versions, projects had to achieve the certified level prior to ean the Regional priority credit (RPc)points. 

I cannot find any statement in the reference guide that confirm or infirm this requirement.

In LEED v4, can a project count on RPc points to achieve Certified level?

All mention of establishment periods refer to the no potable water/irrigation case (WEc1 Option 2), but what about for Option 1, 50% non-potable water use reduction?

If a 50% reduction in potable water use for landscaping is demonstrated using the LEED calculation or WaterSense Water Budget Tool* (WEc1 Option 1), is it acceptable to include additional temporary irrigation for 2 years** for the purpose of establishment? 

*LEED Interpretation ID#10440

**The 2 year establishment period for Option 2 is from CIR 1311.

Hello, 

We are working on a CI project that changed the toilets only few years ago with 6lpf. Less than 3 years.

We can not change only the tank of these toilets so we would have to change it all.

We installed very low flow fixtures everywhere: urinals changed to 1.89 lpf, 1.89 lpm kitchen sinks, 1.3 lpm bathroom sinks and 5.7 lpm showers. Despite all these efforts, it is impossible to obtain 25% savings (we have 24,48%).

The owner of the building thinks it's ridiculous to change the toilets that have just been changed and we do not quite disagree with his point. In addition, the plumber told us that the building piping is not designed to receive less water and that this could create a lot of clogging problem and even breakage.

Is there any way we can reach 25%? 

Thank you!
