Exemplary Performance for Lab Building

Hello Julia,
Could you be more specific with your question? I don't understand why your situation is unique and/or the view factor can't be applied to it just as is stated in the study (page 50)?

Answers:
1.Yes, that is what the occupant will be typically doing in the space.
2.60" would be sufficient.
3. Since option four requires a decent amount of work to demonstrate compliance. I would suggest that if you do not have a 3d model built of the project in which you could capture images from different positions, i would defer this to the construction phase and take actual pictures. Since the study nor credit requirements state a specific method in documenting this, i would look at covering the the best, medium, and worst case positions in the space. With 3d models you can set up the camera parameters before you place it. This would be one method of establishing the cone of vision as noted in the study.

Use the actual images and compare them back to the ones presented in the study.

If your not sure that the project would even meet the requirements of option for, then you would need to at least look at the worst position in the space.

I'm attempting to document this credit for a Dialysis suite with large windows on three sides to woods and a lake. The patients are in chairs, hooked to the dialysis machine both of which are on casters. Staff attend to the patients and do paperwork in the back of the room. After reading the study, I think I can reasonably assign the View Factor. It is the proving part and I do have photos that is becoming harder to guess at. The study doesn't really quantitatively state how they rated the primary and break views. Here are my thoughts and questions.
1. Patients primary view is in front of them even though they are not working on a monitor. But the chair and dialysis machine move and we are expecting the chairs to be angled towards the windows. All the drawings show the chairs parallel to the main run of windows. Do we rotate chairs in anticipation of primary view?
2. Break view for patients then is what? Can we assume a 60 degree turn of the head? Can we then further assume that they will choose a break view towards the windows?
3. And staff, yes they have computers but patients are their primary view. Also as they work with different patients, this view changes. Do we measure both primary and break views as outlined in the study even when the amount of computer time is more in line with break view time? Can we quantify the amount of time staff is at their workstation versus working directly with patients and average them? What about the time staff spends in ancillary spaces doing things like getting medications and dealing with trash?

I'll wrap up by saying this space should absolutely meet the definition of quality view.

You could document exemplary performance with the other options just as easily rather then trying to prove your reason for you choosing the view factor. A space with 3 sides of vision glazing and great views sounds like easier options.

I've never seen, nor do i believe you will need to provide images and calculations clearly separating break and normal view. B

Since you'll be using images, take one from the patient chair with them looking forward, then another with looking at the window. Provide a floor plan indicating the location of the image and the direction taken in. Chairs should be orientated how'll they be used. Don;t over think it.

In regards to the staff, just pick the one location where they will be the most. Just like a hospital, a nurses station would be the spot to take the image from, not the patients bed side, not the exam room etc. You'll go nuts trying to figure out everywhere a nurse goes during their shift.

This is all based on your description and what i imagine the space to be. Send me images if I'm assuming something wrong.

Todd,

Thanks for the advice. We did document this credit successfully and documented the EP as well. The results were interesting on views were interesting and it came out to LEED math. We ran all 4 scenarios and had results from 89% to 94%. We did not actually earn the Quality Views EP. (There was one person too many in another portion of the building.)

Susan

congrats
