Dear all,

as our project meets the requirements of Path 4, we like to submit 4 Points in LEED online. For Option 4 under LEED v4 only 3 Points are available at the thresholds. Is it possible to earn 4 Points for Path 4 in LEED v4 by substituting the credit and if yes, how should we submit it in LEED online?

Thanks in advance and best regards,

We are planning to comply with the strategies A, B, C and F. The strategies A, B and C should not pose a problem. However, I am not sure about strategy F:

Work surfaces will be grey-white with a reflectance of 67%, but there will be no movable partitions. Will we still be eligible for the credit?

Hi! There are big medium and small meeting rooms featuring presentation walls. They all have direct lighting from above the tables. In the big and medium rooms there are multiple lamps which can be seperately controlled, whereas the small meeting rooms only feature one lamp per room without seperate control.

Is credit achievement impossible with this setup?

Thanks in advance!

Hello,

one of our projects is set to deploy automatic lighting controls depending on the actual daylight reaching a certain space. The interior lighting will be steplessly dimmed according to the current lighting situation. In addition motion detectors will switch the light on, only when persons are present. A manual overwrite is possible but only from two panels per floor, which means that not every space is visible from the panel it can be controlled from.

The way we see it, comfort is increased because the occupant doesn't need to move for the lighting to adjust to the actual needs and the dimming happens steplessly and not in the demanded minimum of three levels. Another advantage is energy savings.

Will this satisfy the credits requirements?

Thanks in advance!

Dear all,

is for Option 2 Prescriptive a glare control needed for a seating area with self-service in a hotel, even if the VLT x WFR is so low, that parts of the rooms had to be left out of the lighting zone? On the side of the design no glare protection is desired, but the floor area is too large to let it fall out of the credit completely. A simulation is only intended as a backup, but is not planned.

Regards and please excuse my bad english,

Hi,

I'm working in a project based in germany which is trying to achieve the credit for "Green power and carbon offsets". It's intended to buy electricity which is 100% renewable. The supplier isn't certified (green-e or EKOenergy), but by "TÜV Nord".

It is certified, that 100% of the electricity is renewable and can be traced back to the originating power source/plant. The certified company has to establish sustainable energy supply as a core issue /corporate goal. Any income generated by the higher price of certified electricity has to be used as investment into renewables and shall not be used to increase profits.

Is that enough to meet this credits requirements or has it to be EKOenergy-certified? The "guarantee of origin" shoeld be proved with this certificate, right?

There are different requirements lavatory faucets (Public vs. private (residential)). We are working on an office building that is not open to the public. The project designer is argueing that this means it is private.

Which is the correct minimum requirement for lavatory faucets? Is it public (i.e. 20% reduction on 1,9l/min) or is it private (i.e. 20% reduction on 8,3 l/min)?

Dear all,

in our office project we will use public lavatory restroom faucets that has infrared sensors which detects hand movement. So water only runs when it’s needed. In this case the default duration of 30 seconds are to much in my opinion. What do you think?

Dear all,

As many of you may know, up until now ROS such as office rooms (Office), Bedrooms(Residental), etc. are not required to be mechanically cooled and sometimes not even ventilated in european countires. When modeling, what would be the equivalent in the Baseline case model?

Let's say we go as per ASHRAE App-G TbG3.1-1.Section "b" (All conditioned spaces in the proposed design shall be simulated as being both heated and cooled EVEN IF no heating or cooling system is to be installed...). But what does it mean in practical terms?

OPTION A) Should be configure a Cooling system in Proposed case model the same as if would be in the Baseline case one (e.g. The same system type, fan control, cooling type, efficiencies, etc.)?

or

OPTION B) Or simply add these room areas to our actual Proposed case HVAC cooling equipment -without additional cooling capacity to the actual chiller-?

*The same question applies to the Ventilation, if it is being Naturally Ventilated...

Thank you so much in advance for your quick response.

Hi,

i have a question regarding the calculation of the daily average and peak total occupants, because we received a review commnt on this topic. I have no idea how to calculate it and i didn't find anything helpful so far. So, i'm sorry if this question already came up.

The project is a hotel and the rating system is LEED v4 BD+C: HP. We calculate the default occupancy according to Appendix 2 of the Reference Guide because the hotel operator didn't know how many employess there will be. According to the table there are 44 FTEs and 93 visitors, hotel guests were calculated according to the Getting started section (Hotel rooms *1.5 *0,6) and is 161. So, the review team askes for a description of the daily average and peak total occupants. My question is now, what are the mubers of the table of A>ppendix 2? Average or peak? And how can i calculate the avergae and the peak? I don't understand why there is no clear guidance about that. It is important for planning.

I'm thankful for any help and advice
