Standards are guidance documents developed by groups

that have (hopefully) studied the area and are making

recommendations. Thus, standards are not legal

requirements unless something or someone else has madethem a requirement.

Standard setters include the American Society of

Refrigeration and Air-conditioning, Engineers (ASHRAE),

Illuminating Engineering Society of North American (ISENA),

and American Council of Governmental and IndustrialHygienists (ACGIH).

Legislation

AEE/ Certified Energy Manager CEMAEE/ Certified Energy Manager CEM DD -- 33

Legislation is a law and thus the subject matter covered is

required legally. Legislation must be passed by some

governmental authority to be a law.

Often legislation is somewhat vague and the manifestation or

full explanation of the requirements must be written in "codes.

In US, the Resource Conservation and Recovery Act (RCRA)

is a very famous federal law.


4/16

Codes


Codes are the manifestation (or written legal requirements) of

legislation.

Legislation and codes may and often do draw from standards.

For example, many state building codes draw their technical

strength from ASHRAE 90.1.

Egyptian Organization for Standardization and Quality Control (EOS)under the Ministry of Industry and Mineral Wealth (MIMW). The mainfocus of EOS is in the areas of standardization and quality control

General Organization for Exports and Imports Control (GOEIC) under theMinistry of Supply and Trade (MST). The main objectives of GOEIC are:

The examination of exports and imports

Preparation of the associated statistical reports and analysis regardingexports and imports

Preparation of financial balances regarding exports and imports

Issuing imports permissions
