Hi,
Based on Kingston's EPW file of Onebuilding, the CDD above 10 C is 6448. BTW, above 18 C is 3528.
Hope it helps.

Best,
-A.

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 days

Regards

Ahmad

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?
