Hello Paul,It might be difficult to find the CDD of Jamica based on 10 C but you can calculate it if you have the mean daily temperature over 365 daysRegardsAhmadSent from my Galaxy

I am in the process of revising the Jamaica Energy Conservation
Code and would appreciate any advise on the captioned matter.?
Jamaica's current building code classifies it as being in zone 1
of the International Energy Conservation Code (IECC): which is
equivalent to the classification for Puerto Rico, U.S.Virgin
Islands, and Hawaii.? However the 2021 IECC has introduced a new
climatic zone '0' for extremely hot climates.? The previously
mentioned islands have retained the zone 1 classification.? So we
wish to confirm whether the same applies to Jamaica.
Based on the 2021 IECC definitions, their climate zones are
dependent on the range of cooling degree-days (CDD) above 10
degrees Celsius (C), as follows:
Zone?? Cooling Degree Days > 10 deg. C
0????????? CDD> 6,000
1?????????? 5,000 < CDD < 6,000
Jamaica's current code simply describes it's capital,Kingston, as
having cooling degree-days above 18 deg. C. that is greater than
3,235. ?Could any of you advise where I could find Jamaica's
cooling degree days above 10 deg. C., so that a decision can be
made as to which climate zone is applicable?
