Rooftops Provide Huge Opportunity For Solar Development

Los Angeles is a prime area for solar power, and its development space is growing. More than 12,000 acres are available on rooftops across the city, which could net families and business owners up to five gigawatts of power. This clean energy reduces oil dependency, helps the environment, and over time cuts energy costs. This broad new opportunity provides the perfect time for solar training.…

Correctly Sizing a Capacitor

I don't know how many times a technician has said that they installed a part based on what was on their service truck.  I have heard of technicians wasting money over-sizing contactors, cutting down air filters, and even using controlled substances to clear condensate drains!  Of course, these scenarios all get the job done, but I would argue the many reasons why not to do these.  The one thing that gets to me is when a technician doesn't verify they are installing the correct size dual run…

How Does Air Conditioning Work

Author Note: Here's
 a link to the original post on
 Energy Auditing Blog. Also, it was written to prove that a Mainer does understand air conditioning, at least for the 9 days a year we need it.

 

It's time to turn to cooling thoughts, even though Maine didn't actually get a winter this year. It's true; we had an…

Spending on PV Equipment in Q2’12; Strong Growth Forecast from 2013 - 16

With the modern innovations made possible through technological breakthroughs, now occurring almost daily, many are becoming increasingly concerned with the negative impact these modern conveniences have on our environment. Never has there been a higher demand for individuals who have gone through solar panels sales training and possess NABCEP Certification.



Most people, when posed with the question of how they can make a positive difference on the environment, are sure to mention…

Realistic Expectations and "The Occupied Zone"

How many times as a technician have you gone out to the same customer's home because of unrealistic expectations?  Some homeowners expect air-conditioners to work like an ice box, want you to size them for their big party on Fourth of July weekend, and expect you to show up at the drop of a dime when it doesn't meet their impossible notion.  Of course, this could be avoided by establishing a standard during the sales process or a little customer education.  I liked to talk about "The…

Solar Power Moving Forward at Light Speed

Just decades ago, solar power was an idea that had not yet reached its time. However, that has changed dramatically as the global community seeks alternative sources of power. The demand for solar energy rose 40% in just one year alone, making this renewable resource one of the fastest growing industries. The earning potential of businesses involving solar power could be astounding in the near future. Individuals qualified in the industry will no doubt have the advantage over their…

Editorial: Reflections on ACI

An industry's health is sometimes measured by the enthusiasm of its trade shows. Arguably, ACI is not a trade show, but it certainly is a bellwether for the home performance industry. And it rocked. By all measures, ACI was larger, broader, and more exciting than past conferences.

ACI continues to be a magnet for audiences ranging from contractors just starting out and receiving blower door training to engineers and building scientists. In this way, it serves as the premier…

Energy Efficiency Ratio (EER)

Energy Efficiency Ratio, or EER, is a way to exhibit how well an air-conditioner is operating based on the power being used.  Most homeowners are of course familiar with SEER, the ratio across an entire season.  Since SEER is tested at a "partial load", the EER is a more realistic number to use when figuring energy savings.  AHRI tests their EER of residential air-conditioners using 400 CFM per ton of airflow at 95F Outdoors / 80F Indoors and 67F Wet Bulb.  This compared to the SEER testing…

The Electric Car Market Expands

However, it appears that these two companies aren't the only ones trying to get in on the electric car market; it was recently reported that Hyundai Heavy and Magna-E Car Systems have come together under an agreement to develop next-gen lithium ion batteries. Their goals reach far and wide, as Hyundai hopes to have 30% of the electric car market in Europe and North America at some point or another.



With this many car-makers trying to make their way into the electric car industry,…

Energy Out West

The Energy Out West conference is held every other year and began in 1996 when a group of people doing weatherization work in the Northwest thought they could help each other do it better. The current president of Energy Out West (EOW) is Mimi Burbage, who should be familiar to readers of Home Energy and anyone in weatherization. Mimi brings that independent, Alaska, straight talk style to whatever she does, from heading the Alaska Housing Finance Corporation to her work for EOW.…

ACI National Home Performance Conference: Setting the Pace for Change

This year ACI held its largest ever national home performance conference in Baltimore, Md.  It was the largest in the number of workshop sessions: over 195 sessions, in 25 thematic tracks; with the largest number of exhibitors (115) and sponsors (48).  

The three themes stood out: a) keep it simple (from the homeowners perspective); b) there is no silver bullet; and c) HVAC is jumping into home performance, maybe not head first, but at least with both feet in a measured…

Non-Condensables? Are you sure?

  Non-condensables in a residential split air-conditioner can be, for most technicians, a pandora's box to diagnose.  Fortunately, there is a simple process that can identify this condition without spending hours and hundreds of dollars in virgin refrigerant.  I think we all are aware that R-22 has hit an all time high, so getting this right is more important than ever - if you want to retain your customer.

  There are several ways air and/or water vapor can enter a sealed system. …

President Obama calls for a strategy "that relies less on foreign oil and more on American-made energy"

A strong commitment to the development of alternative energy has been made by President Barack Obama. In a recent radio address, the President called for a strategy "that relies less on foreign oil and more on American-made energy". These renewable energy sources, which include solar and wind power, will not only help wean the U.S. from fossil fuels, but create thousands of new American jobs. Solar training of these workers will be an important part in expanding alternative energy…

How To Reduce Energy at Home

9 Steps to a More Energy Efficient Home and Lower Power Bills



How to reduce energy at home has gradually become a household desire as a result of high definition T.V.'s and homes the size of a castle. Throw in a struggling economy and the melt down of a nuclear plant and becoming more energy efficient seems like a great idea.

Our power bills rise as a result of increasing power costs and the need for more and more power to operate are power hungry homes and…
