I've been using building=industrial to tag my workplace 
http://www.informationfreeway.org/?lat=7554979.16268&lon=-376067.709&zoom=16&layers=B000

There are also some building=school and builing=storagetanks in that area.

Render wise, the tiles at home layer will render anything tagged as a 
building.

mapnik doesn't seem to do any building rendering.

osmarender4 has the following building rules defined:

            <rule e="way" k="building" 
v="barn|warehouse|oast_house|tower|castle|monument|hall|shed|store|stadium">
                <area class='building'/>
            </rule>
            <rule e="way" k="building" 
v="barn|warehouse|oast_house|block|tower|castle|monument|hall|shed|store|stadium">
                <area class='building-block'/>
            </rule>
            <rule e="way" k="building" v="detached|semi|terrace|apartments">
                <area class='building-residential'/>  

The Map_Features page on the wiki doesn't list any building features, 
and it doesn't even make the "Proposed Features".

My suggestion to you would be to tag things with the most appropriate 
tags, if you use the building tag then it will be visible on the 
tiles at home layer now. My view is that putting this extra detail in will 
give maps generated and OSM in general that extra edge, that will make 
people say wow.

Remember that there is no such thing as incorrect tagging in OSM....   
(just tagging that doesn't get rendered)

Cheers
Chris
