43 HVAC System Design Goals, Objectives and design philosophies

The design criteria established for the facility HVAC system as presented in this report aims to ensure a high level of cleanliness and comfort as would be essentially required and expected within the proposed buildings. Also, the system should conserve energy and be designed for minimum maintenance, efficient operation and reliability.

Space cooling is required to remove heat generated by solar radiation and transmission, lights, power and people. Ventilation is required in order to maintain a balance of oxygen, carbon dioxide and other gases. Air distribution is required in such a manner as to distribute air evenly throughout the conditioned space in order to maintain consistent temperatures and comfort levels without objectionable noise.

Functionality, operability and maintainabilityo To develop safe, reliable, maintainable, energy efficient and economical installation for

the project.

prevent water condensation.

44 Design approach

Since the building has many different functions, the design is to consider the requirements for each function separately. The functions as introduced in the introduction are: Female & male administration offices. Electric & Telecommunications rooms. Retail shops & food court. Library. Common area. Parking area.

For each of the above function areas, the parameters affecting the HVAC design has been evaluated, such as: Fire zoning & fire barriers. Occupancy density and profile. Heat load source. Envelope materials, insulation and forestation. Floor area and circulation.Preliminary heat load for each area has been calculated. HVAC system has been selected to meet design objectives and goals. The area may be divided into HVAC zones. Each zone is served by a set of equipment.
