After The Energy Audit...






http://www.greenintegrateddesign.com/blog/after-your-energy-audit

If you have an energy audit done for your house, feel free to give yourself a pat on the back. You just took the very first step to a more efficient and comfortable home. 

But it's not over yet! You may have been given small verbal updates on the state of your house during the audit, but the true results don't come in until later. You should have a follow-up appointment scheduled soon after the initial audit, where you will be able to see your audit report in-depth and be able to ask questions about it. This is where you might receive a list of possible fixes for the found inefficiencies in your home. 


​The next step is to make a plan! Write down what issues you want to prioritize, and what solutions you want to use on them. ​A good portion of the expected work might require professional touches. But don’t think you can’t do anything yourself. Some quick DIY fixes, along with the additional fixes your home might need, can have your AC running in tip-top shape even as the summer heat rages on outside.

Home energy saving tips with a water heater timer


Lower your energy bills with a water heater timer. APS utility rates double during peak hours in the summer. SRP energy rates almost double during peak summer hours. This water heater timer shown by energy auditor David Byrnes of Green ID can turn off during peak hours, saving valuable kWhs. In Phoenix, it's impossible to get cold water during the summer anyways so why waste energy with your water heater. Save money and live happy with Green ID.

How To Perform A Variable Speed Pool Pump Calibration & Save Money On Your Energy Bills

As energy auditors and home performance contractors we often find variable speed pool pumps that have never had a proper calibration. Although we do install Hayward and Pentair variable speed pumps because of the great energy savings realized, a post-install calibration can be performed DIY. Here are some easy steps to follow to save money on your energy bills and get the most out of your variable speed pool pump.

APS Rebates for Home

APS has come out with great rebate programs and solidified their commitment to 1) energy retrofits upgrades like duct sealing and insulation, 2) renewable energy products like solar panels for electricity and hot water and finally for 3) switching out old appliances.  Each of these rebate programs are separate entities that sometimes get confused since they are always changing.  For example, APS solar rebate program has seen better days when solar electricity rebates used to be at $3.00 per watt.  Every couple of months for the last 2 years APS has dropped their solar rebates until the current amount of $1.45 per watt.  Now the best and most affordable way to get solar is through a solar lease program that significantly buys down the costs of solar panels.
Now the hot program is APS’s and SRP’s Home Performance With Energy Star.  This is a national Energy Star program to make homes more healthy, comfortable and efficient.  APS and SRP adopted the program to ensure a whole-home approach to reducing energy bills while keeping homeowners safe and with better indoor air quality.  APS requires a $99 energy audit be performed on a home to diagnose the causes of high energy bills, uncomfortable rooms or excessive dust.  Once the audit is complete a report will be generated using building modeling software that gives cost savings for each upgrade.  The APS rebates will help pay up to $1,000 (or more if you have two or more AC units) off the costs of the energy retrofit.  The rebates for the Home Performance With Energy Star program are broken down below.
Duct sealing 75% off up to $250 per unit.  For most homeowners, 20% of their heating and cooling bill is wasted from duct leakage.
Air sealing 75% off up to $250.  Air sealing work can be complex as your auditor must determine
Insulation75% off up to $250
Shade screens $1 per sq ft up to $250
APS has a great visual summary of their rebate program here.
APS rebates for pool pumps
$200 for variable speed pool pump.  Each pump has to be calibrated to your pool to ensure that it is not over turning your pool.  This upgrade will reduce your bills $200 - $350 per year.  APS also provides a $75 rebate for pool timers.
APS Rebates for AC units
Air conditioning systems have become more efficient from federal standards and better technologies.  Surprisingly, APS does not overlap its duct sealing rebates with its air conditioning rebates.  With every unit we install, we include a whole home duct seal to maximize the high efficiency AC unit with a properly sealed duct system, otherwise it’s like using an umbrella with holes in it.  APS will help you pay for a higher efficiency AC unit depending on the efficiency ratings.  In the AC efficiency world there is a SEER rating, the seasonal energy efficiency ratio, EER rating, the energy efficiency ratio, and HPSF or .  In Phoenix, the EER is a more important number to pay attention to because of how hot it gets here.  The EER ratio gives a better idea of how an AC will perform under very hot conditions (100 degrees) were the SEER rating gives an idea of performance under milder conditions (89 degrees).  SRP recognizes and awards a higher rebate with higher EERs in their AC rebate program, but APS does not.
APS also has a quality installation standard similar to the post test done for the home energy audits that has to be met when installing heat pumps and furnaces in the Phoenix area also.  Only APS qualified AC companies can apply for their rebate for you, but not all of them will perform a duct testing and sealing upgrade.  These rebates and companies are separate from the solar rebates and the home energy audit rebates.  All the APS approved AC companies are required to do a sizing calculation called the Manual J calculation.  You should ask to see the results from your own home to ensure this was done.  The AC rebate program also includes a check of the refrigerant charge to make sure that the unit is properly charged to manufacture specifications and a check of the air flow.  Below is a list of the AC rebates available from APS.
SEER 13 with EER 10.8 receives $175 APS rebate
SEER 14 – 16 with EER 10.8 receives $425 APS rebate
SEER 17 with EER of 10.8 receives $525 APS rebate
All units must be installed by and APS approved AC contractor.
All contractors must perform a Manual J calculation to properly size the unit (you should verify this since it is not something a typical contractor will do).
All contractors should properly charge the unit and check airflow.

APS Solar Rebates
APS solar rebates are divided into solar electricity rebates and solar hot water rebates.  Solar electricity for my home was my dream growing up and has proven to be an attractive idea to thousands of homeowners across the Phoenix valley.  APS perhaps did not realize how attractive solar electricity would be since they have lowered their rebate amount dramatically since its inception.  As of May 2011, APS solar electricity rebate is at $1.45 per watt.  You can view their current budget and remaining monies available at the link below.
APS Solar Hot Water Rebates
After City and County applications have been approved, APS does random inspections of the installation.  The solar hot water system must be SRCC rated and have proof onsite.  The first 5 feet of your hot and cold water piping should be insulated to at least R-2.6.  The panels must be un-shaded during the day for the entire year.  The APS solar water heater rebates are currently at $0.50 per kWh of estimated first year savings (based on the OG-300 ratings), up to 505 off the system’s cost.  The OG-300 rating system is based on the manufacturer’s rating by the Solar Rating and Certification Corporation.  Also important to consider for solar hot water systems is the federal tax credit of 30% off the cost and Arizona state tax credit of $1,000, which makes solar hot water much more attractive.  Typical solar hot water rating systems are around 2,890 kWh per year.  An example rebate table is shown below.
Solar Hot Water Cost $5,400
APS Solar Rebate $1,445
 Arizona Tax Credit $1,000
Federal Tax Credit $1,620
Net Cost $1,335
Annual Savings $425
Simple Payback 3 years
APS Appliance and Tree Shading Rebate
APS also provides a $30 rebate to replace your old refrigerator and they will even come and pick it up for free.  Also, a understated home comfort and energy saving rebate APS offers is to plant external shading along your home to block direct sunlight.  The requirements of this rebate are that you attend a free tree shade workshop and can legally and physically plant shading trees along your home.  Visit the link below for more information.

Save Energy While on Vacation or Away for the Summer

A good number of the APS and SRP home energy audits I do are for eco-conscience snowbirds.  These residents typically reside in the Phoenix, Surprise and Scottsdale areas during the winter and go back north for the summer months.  Even though homeowners are only here for part of the year, many are still motivated to have the upgrades done because of comfort and air quality problems.  Other homeowners will have efficiency upgrades like duct sealing, air sealing and insulation work done because of the APS and SRP rebate program and to drive down energy costs.  During the homeowner interview, I am always interested to find out what each homeowner does to “summarize” their home.  For Phoenix’s permanent residents, the summer is a time many will take vacation for more temperate climates.  Either way presents opportunities listed below to save energy and money while away.
Tips for “Summerizing” Your Home While on Vacation
-          Turn the water heater off completely at the breaker or shut the gas line off.  At the least, set the dial to vacation mode to minimize stand by losses.
-          Turn the thermostat up to 90 degrees.  This will keep your home cool enough to not damage the structure or your belongings.
-          Fill gallons of water and place several throughout the house to add moisture over time.
-          Unplug energy vampire’s aka electronic devices.  TV’s will use more energy in stand by mode than when turned on.  Prevent wasteful spending by simply unplugging your electronics while away.
-           Keep window shades closed and sun screens on the exterior windows to minimize heat gain during the daytime.
