According to the EPI Data Centre Professional (CDCP) Reference Materials, a core objective of a Business Value in an organization is to create value for customers and stakeholders1. This means delivering products or services that meet or exceed customer expectations, while also generating profits or benefits for the organization and its shareholders. Reducing costs, reducing the deficit, and increasing sales are possible ways to achieve this objective, but they are not the core objective itself.

Class D fires involve combustible metals or combustible metal alloys such as magnesium, sodium and potassium. These metals can react violently with water, air, or other chemicals, and require special extinguishing agents1

A computer room air handling unit (CRAH) is a device that uses circulating chilled water to remove heat from the data center environment. A CRAH consists of a fan, a coil, and a filter. The fan draws the warm air from the data center and passes it through the coil, where the heat is transferred to the chilled water. The chilled water is supplied by a chiller or a cooling tower, and the cooled air is returned to the data center. A CRAH is different from a computer room air conditioning unit (CRAC), which uses a refrigerant instead of chilled water to cool the air.

Physical separation is the most cost-effective method to minimize electromagnetic interference. Specialized shielding is more expensive and usually unnecessary if proper separation is maintained.

According to the Certified Data Centre Professional (CDCP) reference materials, ICT (Information and Communication Technology) equipment such as servers, switches, and storage devices generate sensible heat. Sensible heat is the heat energy that causes a change in temperature of the air but does not contribute to humidity or moisture content. This is in contrast to latent heat, which involves a change in moisture (humidity) in the air, such as from evaporation or condensation.

ICT equipment does not introduce moisture into the environment; it only raises the temperature of the surrounding air, making it sensible heat. Proper data center cooling focuses on removing this sensible heat load to maintain optimal equipment operating conditions. Latent heat loads, such as those from people or water leaks, are typically not generated by ICT equipment and are managed differently in facility design.

Radiant heat is a minor consideration and typically refers to heat transferred by electromagnetic waves (e.g., from sunlight or hot surfaces), not the primary mode of heat transfer from ICT equipment, which is primarily through convection (airflow) and is measured as sensible heat.
