manual control clarification for translucent glazing

Hi Elaine, yes, most translucent glazing will eliminate glare.  

Option 1 gives up to 3-4 potential credits and based on our experience, people that regularly create Option 1 scorecards will get 2 points on average (before optimizing), versus just 0.15 for Option 2. Simulation will also tell you if your 100,000sf space meets the daylight sufficiency requirement (which will depend on how deep the space is, number of clerestories, etc).  

Step 5 in the LEED Reference Guide states translucent and diffused glazing systems do not require glare control devices. So you can use translucent glazing in the clerestory.  My experience has shown that the rule of thumb of at least 10% toplighting area to floor area will get you close to having sufficient amounts of daylight in the space. Now this is a starting point and will need increased based on orientation and the VLT. I could not say whether your strategy would meet the credit requirements without alot more info. So many factors, geometry, orientation, other glazings, interior reflectances, orientation, climate etc.   Here is the other thing, if you did not put the daylight performance into the DNA of the design, that is design the space so that daylight provides a specific amount of the lighting requirements, then the end of the project simulations could cost alot of money and time to just show you have poor daylighting.
