Question
This section of the code references ASHRAE standard 90.1 under the heading Electrical power. Although the Florida Energy Code does not explicitly say to provide automatic receptacle control, the reference to ASHRAE 90.1 does require it. Many professionals in the field do interpret that it is therefore a requirement in the Florida Energy Code. I was just looking for clarification on this topic for my own edification in case the question comes up in the future. Is automatic receptacle control a requirement in the Florida Energy Code?

The short answer is,Yes, it is required. Please see the attached commentary for more information
Commentary
The Florida Building Code, Chapter 35, contains the list of referenced documents and standards referred to throughout the code. Rather than place each and every referenced piece of information, around 500 of them, in the Code and be required to maintain and update that information, in addition to concerns regarding copyright laws, section 102.4, copied below from Chapter 1 of the 6th edition FBC makes it clear the specific sections referred to are considered to be a part of the FBC and complied with as if written in the book, This is why it is important for practitioners of the FBC to not only have the FBC, but, the referenced standards as well, or at least the portions of the standards that are referred to in the code.

The codes and standards referenced in this code shall be considered part of the requirements of this code to the prescribed extent of each such reference and as further regulated in Sections 102.4.1 and 102.4.2.
