Energy Efficiency

The math works out something like this: the original HVAC system in our example burns 8 fuel units per minute and runs for 12 minutes per hour, so, it consumes 96 fuel units per hour.  The upgrade unit that the HVAC contractor recommends as a replacement consumes 10 fuel units per minute but runs for just 10 minutes per hour so it burns 100 fuel units per hour.  Unfortunately, warm air still rises to the ceiling so a few months later the HVAC contractor returns to install an additional $1,000 accessory air circulation device that runs continuously and consumes just 15 fuel unit per hour.   Now, you finally feel like your new, $10,000 HVAC system is working; but, your new system is consuming 115 fuel units per hour when your old system was consuming just 96.  Well, there are 8,760 hours in a year and your thermal conditioning costs have just risen by 20%.  Add to that the fact that average energy costs generally rise from 4% – 8% per year and it is clear that a considerable financial mistake has been made.

What would actually have worked better, cost half as much to purchase and effectively reduced energy consumption is a new HVAC system that burns just 2 fuel units per minute and runs for 40 minutes per hour circulating air constantly.  It would consume 80 fuel units per hour, cost just $5,000 and would meet your heating and cooling load while decreasing your thermal conditioning costs by 17%.  In all honesty, during periods of record breaking heat, the system may only cool to 78 degrees and during record breaking cold spells room temperature could be 62 degrees.  That is just a day or two per year!  The HVAC industry says you must be constantly capable of meeting that maximum potential demand.  What do you think is right for your building and your budget?

Energy efficiency is right for every building and every budget!  Energy efficiency is right for our country as it reduces our dependency on imported fossil fuels.  Energy conservation is, quite simply, the civic and moral responsibility of every American.  When people stop wasting energy everybody wins; so, why aren’t we paying more attention to energy efficiency when we design buildings and select their mechanical systems?  It is because the industry that we go to for answers to these questions provides us with a biased view of what is right for our buildings.  That bias is generated by the profit potential of that industry.   Would an HVAC contractor that is proposing a new furnace for your building tell you that just a small investment in insulation would enable your existing furnace to effectively heat the building?  Would an HVAC contractor that is proposing a new AC for your building tell you that just a small investment in window tint or awnings would enable your existing AC to effectively cool your building while running less and reducing energy consumption costs?   An energy efficiency consulting firm like Energy Liberty Corporation would definitely explain these options to a property owner.  An energy efficiency consultant does not care whether or not the HVAC contractor “makes the sale”.  An energy efficiency consulting firm is entirely focused on the best interest of the property owners that it serves.
