HVAC Upgrades

Replacing old boilers and heaters with high efficient equipment and updating a building's HVAC system will result in significant savings on your energy bill and make your space much more comfortable.
In most cases, heating and ventilation make up the majority of a building's energy use.

What is it?

HVAC refers to the three disciplines of Heating, Ventilating, and Air-Conditioning. Heating can be accomplished by heating the air within a space, or by heating the occupants directly by radiation. Ventilating maintains an adequate mixture of gases in the air we breathe, controls odors, and removes contaminants from occupied spaces. Air-conditioning refers to the sensible and latent cooling of air.

Heating, ventilation and air conditioning (HVAC) systems supply fresh air and condition the indoor air temperature and humidity of a building. HVAC systems are one of the largest portions of a buildings energy use and increasing their efficiency is a key component of reducing energy consumption in the building sector. High efficiency HVAC systems can be achieved through proper integration of heating, cooling and ventilation sub-systems for a specific building type to eliminate drafts and wasted energy.


Taking Action

According to the Whole Building Design Guide, HVAC system upgrades have the potential to save 10-40% of a buildings conventional costs, energy use, and GHG emissions. Furthermore, these reductions can be directly translated into significant savings in electricity and gas bills for the building owners and/or tenants. High efficiency HVAC systems also deliver cleaner and better quality air resulting in better indoor living and working environments, reduction of sick building syndrome, and better living comfort and productivity.

Maximizing energy efficiency with HVAC systems is a two-part process. The first step is to replace or update inefficienct equipment and control systems. The second equally important step is to practice ongoing monitoring of equipment performance and perform timely maintenance to ensure that the HVAC system continues to operate optimally.

Though they are grouped together under the same acronym, each component of HVAC has specific requirements and opportunities for saving energy. It is important to note that energy savings in one area have the potential to positively or negatively impact energy savings in another. Therefore understanding the whole building design and the interactions between all components is crucial to achieving optimal energy efficiency and is a key component of a high efficiency HVAC system.
