Making your home more energy efficient reduces carbon emissions. Small savings from each home add up.

In 2011 - 2012, EUMV helped Mountain View residents keep 475 metric tons of carbon from entering the atmosphere — that's like avoiding the use of 50,000 gallons of gasoline!

With EUMV, we can create a healthier environment.

Why don't you support houses with solar PV?

If you have solar photovoltaic (PV) panels installed, you probably don't have a SmartMeterTM yet. PG&E started installing SmartMeters at homes with solar PV in late 2012 but the meters only record net energy consumption. To perform an energy analysis, we need both electricity production and total energy consumption, so for now, residents with solar PV panels are not eligible for the Energy Upgrade Mountain View program.

I'm a renter, can I still participate?

Yes! Energy Upgrade Mountain View is open to owners and renters living in single-family homes, apartments, condos and townhomes.

How do I know if I have a SmartMeterTM?

According to PG&E, SmartMeters have been installed in all Mountain View homes that are eligible. An easy way to check is to log into your online PG&E account. After you log in, you can access your SmartMeter data by clicking on the “My Energy” tab. If data is not available under this tab, you don’t have a SmartMeter. Alternatively, if you know where your meter is located, check to see if you have a digital or analog display. If it’s analog, you don’t have a SmartMeter. (If you don't have an online PG&E account, it's very easy to create one. Go to the PG&E account access page and follow the instructions for creating an account.)

I wanted an in-home visit but I didn't receive one. Why?

You will receive energy-saving recommendations based on your specific energy usage. Many of the recommendations you receive will be easy and free or inexpensive for you to perform on your own, so in-home support is not needed. A limited number of in-home visits may be performed for homes with energy irregularities or other unusual factors. If you have further questions, you can contact us at

How is EUMV different from Energy Upgrade California?

Energy Upgrade California is a statewide program that provides rebates for various energy efficiency upgrades to a home, such as making heating and/or cooling systems more efficient, installing insulation or performing other generally more complicated home upgrades. EUMV has the same goal as Energy Upgrade California — reducing residential energy use — but the City of Mountain View wanted to address more specifically how Mountain View residents use energy. Due to Mountain View’s mild climate, Mountain View residents use much less energy for heating and cooling than residents in other areas of the state. Because of this, EUMV offers alternate ways to save energy, such as reducing electricity usage from devices, such as televisions, that are always plugged in.

How do you decide which energy-saving solution is right for my home?

We use your Home Energy Profile to help decide which solutions are best. In some cases the selection is obvious: if more than 50% of your yearly energy use is for heating and cooling, your home will probably benefit from upgrading your HVAC equipment, insulation, or windows. In that case, Acterra will contact you with information on the statewide Energy Upgrade California program. However, other homes in Mountain View may be using more energy in the base load, variable load, or pool categories, in which case we will provide you with recommendations and savings information specific to these areas. If you have higher than average usage in more than one category, Acterra will provide you with energy-saving solutions for ALL categories that apply to your home.

What happens during an online audit?

Unlike other audits, where energy efficiency experts come to your house and investigate, most interactions for this audit will occur online, at a secure website managed by EUMV.
  1. EUMV’s online tool collects your energy use data from PG&E and then asks you to provide basic information about your home, such as size, age, number of occupants, thermostat settings, etc.
  2. EUMV’s online tool performs an analysis to segment energy use into different categories (seasonal, base loads, variable loads, etc.), compare your energy usage to that of similar homes, and provide simple recommendations for reducing your energy use.
  3. You select the energy-saving recommendations you will implement — and implement them!
  4. Based on your Home Energy Profile, an Acterra representative may contact you to offer further energy-saving solutions.
  5. You will receive monthly emails analyzing your energy trends, enabling you to track how much energy you’re saving.

What kinds of recommendations will you make?

Your online energy-saving recommendations will vary depending on your home and energy usage patterns. Energy use varies considerably from home to home based on many factors. A key benefit of this program is its ability to break down your energy use into categories and provide a chart of the different categories (also called an “energy profile”), so you’ll know where your energy is being used. You can make smarter decisions about how to conserve energy when you know where your energy is going.
  • Some residents may need help managing electric base loads, so we will make recommendations like unplugging unused electronics or using “smart” power strips—and we will give you detailed instructions on how to do so.
  • Some residents may need help managing electric variable loads, so we will make recommendations like upgrading lighting and electronic systems. These homes may also qualify for a free in-home display device that shows the home’s electricity use in real time. Acterra will provide these devices at no cost and help set them up in your home through PG&E’s Home Area Network program.
  • Some homes may be identified as using an unusual amount of energy for heating or cooling, and they will need further analysis of their heating, ventilation, and air conditioning (HVAC) systems. If so, we will refer you to the statewide Energy Upgrade California program.
  • Some homes may have features like pools, spas, fountains, or whole-house systems that can be made more efficient, and we will provide appropriate energy-saving solutions and referrals for these systems.

I’ve heard about other energy efficiency audits. How do EUMV's online audits differ from those?

There are many kinds of energy efficiency audits available and we know it can be confusing. They often differ based on the emphasis of the audit. Research shows that an increasingly high proportion of residential energy use goes toward base loads (appliances and electronic systems that are drawing power all the time, even when they aren’t being used, like TVs, set-top boxes, and hot water recirculation pumps). Lots of energy also goes toward intermittent plug loads (e.g., refrigerators and pool pumps). The primary focus of an EUMV audit is to analyze energy use in these categories and identify simple and cost-effective opportunities to reduce this electric waste.

Other audits you may have heard of focus primarily on identifying opportunities to improve heating, ventilation, and air conditioning (HVAC) systems, based on in-home inspections and expensive diagnostics like blower-door tests, duct blasters, and thermal imaging. These audits make sense if a majority of the home’s energy goes toward heating and cooling. If our software finds that your home is a good candidate for this type of advanced audit, we will refer you to the statewide Energy Upgrade California program.

What happens if I’m offered the in-home electricity monitoring device?

Acterra will contact you to let you know that you’ve qualified for a free in-home, real-time electricity display device. We will act as a conduit between you and PG&E’s Home Area Network program to help you install the device in your home. The cost of the device and installation assistance will be covered by EUMV. You will still have access to the EUMV Navigator so you can track how much energy you’re saving based on changes you’ve made as a result of having the in-home display device.

Will someone come to my house?

Generally not. Unlike other audits where energy efficiency experts need to explore your house from crawlspace to attic, most interactions for this audit will occur online at a secure website managed by You may also hear from Acterra representatives by phone or email to provide you with additional energy-saving solutions. This additional follow-up could include an Acterra “Green@Home HouseCall” if appropriate. Ultimately, our goal is to help you save energy and money through easy and inexpensive actions that you can take on your own.

How much time does the online audit take?

Depending on the complexity of your home, the online audit may take anywhere from 15 minutes to an hour. You will learn as you go, and there is no need to answer all questions in one sitting. Through the audit, you will be provided with a prioritized list of recommendations based on your energy usage breakdown. Of course, it will also take some time for you to perform these energy-saving actions. Many of these actions can be completed in just a few minutes, but others may take more time, such as purchasing and installing a device. Acterra representatives will be available to answer questions, provide further information on more complicated recommendations, and offer additional energy-saving solutions. If you ever have questions regarding your Home Energy Profile or implementing your recommendations, you can contact After you finish your audit, you will receive monthly emails that track your energy use and savings.

Will my data be safe? Who else will see my information?

Your data will be held in strict confidence on a secure server and will only be used to help you reduce your energy use. Only those directly involved in the audit process, such as Acterra and HEA staff, will have access to your answers. The PG&E login information you've provided does not give EUMV access to your bill payment information, so even if you have registered a bank or credit card with PG&E for automatic payments, we have no access to it.

Because City money is being used to fund EUMV, the City of Mountain View will receive summarized results at various stages. However, all personally-identifiable information (name, address, etc.) will be kept confidential.

What do I need to do to prepare for the online audit?

Nothing. Once you’ve enrolled in the program you will receive an email with a link to your EUMV account where you will enter the information requested.

What happens if I need help?

You can get help from an Acterra staff member by phone at 650-962-9876 x380 OR by email at
