10 HVAC & Energy Efficiency Fun Facts

A little knowledge doesn’t hurt anyone! We’ve been collecting fun facts about the HVAC industry over the past few months from various credible sources, and thought collectively they would make a masterpiece. So read on and you will probably find something out you didn’t know before!

1. Factors such as rightsizing, system updating, and types of refrigerant used can significantly affect HVAC efficiency.

2. An electronic air cleaner is 40x more efficient than a standard throwaway filter in removing unwanted particles from your home.

3. A variable speed heat pump can trim energy costs by as much as 40%.

4. You can increase the efficiency of your home by up to 30% by investing in proper insulation and sealing air leaks around windows and doors.

5. In NYC, it is estimated that poorly fitted air conditioners cost buildings $130 million to $180 million a year in extra fuel consumption!

6. An oversized HVAC system increases installation costs, wastes energy, and costs more in overall operating costs than a correctly sized system.

7. 75% of the electricity used to power home electronics is consumed while the products are turned off – so unplug and conserve!

8. The Romans were the first civilization to use any type of warm-air heating system.

9. The first air conditioner wasn’t for people’s comfort! The first modern air conditioner was invented by Willis Carrier in 1902 for a publishing company in Brooklyn. The machine kept temperature and humidity low so that paper didn’t expand and contract. Carrier never intended for his invention to be solely used for comfort!

10. The top 3 commercial energy uses in the US are: lighting, space heating, and space cooling.

Is it Greener to Retrofit than Build New?

We all know that building new green buildings is always a hot idea, but experts have been pushing the idea that retrofitting existing buildings with green upgrades provide more environmental benefits. Your first thought may be new = better however, there is now proof that these experts are correct from a report released earlier this year. The report found that it is unequivocally greener to retrofit an old building than construct a new green building, no matter how many high-tech bells and whistles are in the new construction. The report was drawn from “The Greenest Building: Quantifying the Environmental Value of Building Reuse” project which was commissioned by Preservation Green Lab.

Elizabeth Heider, chair of the board of directors at the USGBC said “The thought was in order to build green you have to build new.” However, the report numbers add up in favor of retrofits. The report states:

  • It can take between 10 and 80 years for a new energy-efficient building to overcome, through more efficient operations, the negative climate change impacts that come from construction.
  • Environmental savings from re-use are between 4 and 46 percent over new construction when comparing buildings with the same energy performance level
  • The negative environmental impact of retro green for human health was between 12 and 38 percent less than for new construction
  • When it comes to ROIs, retros showed a 19.2% increase in ROI versus 9.9% for new buildings
