Retrofitting

If the heating is provided by electric resistance elements, the lower energy required to warm the space causes lower rate billing charges and lower peak costs as well. Utilities typically see a high peak in […]

In humid climates, a disproportionate amount of the energy of mechanical cooling is used in dehumidifying the air. A desiccant dehumidification system can often handle this latent load more efficiently, leaving the existing mechanical system […]

Duct insulation also helps to reduce noise in the ductwork. This noise is from two sources: (1) aerodynamic noise generated by the flow of air through elbows, turning vanes, takeoffs, and other components of the […]

Whenever there’s a difference in humidity between the conditioned space inside the building envelope and the atmosphere outside, there is a natural migration of moisture to the drier environment to equalize the humidity. The building […]

The fundamental operating principle of air-conditioning systems is to absorb heat from a space at the cooling coils, transport the heat outside by way of the refrigerant fluid, then discharge the heat to the atmosphere […]
