Mechanical
Heating and Cooling
-
Heating and cooling is the control of temperature and humidity of an environment to make it comfortable for habitation.
​
Air Distribution and Diffusion
-
Air distribution is a part of ventilation required to create the optimum indoor environment. A balance is must be found between “draft” and “stagnant” air distribution environments.
​
Ventilation
-
Ventilation is the process of "changing" or replacing air in any space to provide high indoor air quality. The New Zealand building code requires ventilation is achieved in habitable spaces.
​
