HVAC: Heating, Ventilation, and Air Conditioning.

The starting point is carrying out an estimate both for cooling and heating depends on the exterior climate and interior specified conditions. However before taking up the heat load calculation, it is necessary to find fresh air requirements for each area in detail, as pressurization is an important consideration.

In modern buildings the design, installation, and control systems of these functions are integrated into one or more HVAC systems. For very small buildings; contractors normally select HVAC systems and equipment. For larger buildings, building services designers and engineers, such as mechanical, architectural, or building services engineers; analyze, design, and specify the HVAC systems. Specialty mechanical contractors fabricate and commission them.

The scope of work is to improve the energy efficiency of the HVAC equipment installed in the buildings owned by the City of uMhlathuze. This will be a refurbishment project as the current installed equipment is inefficient and would need to be replaced. The HVAC equipment will be upgraded with the objective of making the HVAC systems more efficient. Old equipment will be replaced with new and modern equipment. Malfunctioning systems will be repaired whilst inefficient technologies will be replaced.
