am looking for the building envelope requirements for Climatic Zone 5. As I
read table 5.5.5 (assuming a nonresidential building), the skylight can have a
U-value (of the assembly) up to 6.64 assuming it is made of glass However this
doesn’t give any meaning – since a U-value that high is almost
equivalent to the surface resistance factors (and nothing from the
glazing/gases etc.).<o:p></o:p></span></font></p>
