In order to specify the lighting power density according to table 9.6.1, what is the definition of "Fine material storage"?
The power density of "medium/bulky material storage" is much lower.

Good question. Not sure there is a firm defintion. Did you check the User's Manual or maybe the IESNA Lighting Handbook? For me fine material would be small items, especially those that require the ability to read something with somewhat small print on them but maybe that is my aging eyes talking as I definiately need more light to read small print the older I get.

In the User's manual v. 2016 I have found this, but it isn't a definition: "Assume that the building described in Example 9-L is used as a warehouse for bulky items and that the space contains large storage racks".
What do you think if in the storage there are cardboard boxes?

Big boxes? Small boxes? Large lettering or small lettering? Without a definition you would need to be able to justify the selection you make especially if selecting the higher value. One way to decide - use the conservative approach. If you are unsure pick the lower value as it will not attract additional scrutiny.

Do the required savings for this prerequisite (and credit) need to come only from building energy, or also process loads?
Our project doesn't have enough energy savings to earn the prerequisite. Can we get there by incorporating onsite renewables?
Our proposed design has insulation R-values that are below those prescribed by ASHRAE 90.1-2010. Can we still meet the prerequisite?
