Breaking Down a BGE Energy Audit
Thursday, August 13 2020

 

Everything You Need to Know About a BGE Energy Audit

Often times homeowners don't know what a BGE energy audit is or how it can actually help with understanding more about your home.  

For starters, a BGE energy audit can help you avoid choosing the wrong solution to a problem around your home. An energy audit through BGE is a good place to start your home improvement priority list.  It is also a great place to start if you want a more comfortable home!

This article breaks it all down for you and shows you how getting the audit done can really open your eyes to a few unexpected things!


Why Do You Need a BGE Energy Audit?

A great way to significantly reduce energy waste is to tighten up the envelope of your house. When sealing is done properly your HVAC runs less, pests have a harder time getting in and you feel more comfortable.  Knowing where to look and how to accomplish improving your "building's shell" is the central focus of a BGE energy audit.  

A certified energy auditor will investigate areas of your home that typically do not see much "daylight".  It is the dark corners and small spaces that sometimes yield the most information.  Getting the service done just to have a trained pro to check out the attic or crawl space is well worth the small investment of $100!


What Kind of Service is a BGE Energy Audit?

Not every contractor in Maryland qualifies to perform a BGE energy audit.  Improving your home's building shell tightness is not as simple as adding more insulation.BGE Home Energy Audits Maryland

Energy auditors have to be certified as Building Analysts to identify what a house needs. Calculating the number of air changes per hour your house leaks air is part of  the assessment.  You can see examples of interesting things we find tied to air leakage here.

A BGE energy auditor evaluates your house as it stands now. The auditor accurately takes a "snapshot" of your home's energy performance.

Health and safety testing, pressure readings and an air leakage test are all data points needed to complete the energy audit.  Other evaluations depend on age, symptoms and preexisting conditions.


What does a BGE Energy Audit Test Around Your House?

Health & Safety Testing

There are several health and safety tests that are performed during a BGE energy audit.  You can expect the following:

  • Combustion testing of any gas appliances
  • Carbon monoxide testing
  • Gas line leakage testing

Air Flow Testing

Ventilation is an important part of healthy living and must be part of the overall plan to improve efficiency.

  • Measure exhaust fan ventilation speed
  • Blower door testing
  • Duct leakage testing

Take the important step of scheduling your BGE energy audit as soon as you can!  It's a steal at $100!
 

How Can a BGE Energy Audit Give You a Check-In on Your Home's Indoor Air Quality?

Indoor air quality is commonly misunderstood as a number calculated in particles.  Instead, it refers to getting fresh air into a home.

A BGE energy audit is a great way to determine what your indoor air quality "score" is and how to fix any deficits that may exist. A great way to figure out indoor air quality is to consider a common misconception.

A very good carpenter that works around houses every day once said to me during a discussion about air sealing a house:

"Well gee, don't you need to let the house breathe?"

This comment has a direct tie to indoor air quality.  The answer is, YES, of course.  But, what we need to discuss is the difference between uncontrolled and controlled "breathing".

With the use of sophisticated modeling software, data collected during the audit will calculate the required air changes per hour for each individual home that is inspected.  The assessment looks to tighten a building's shell, therefore calculations are made as the house stands now and projections are calculated if the house is tightened.

The great thing about the BGE energy audit is that you can find out your indoor air quality status now without getting any additional work done.  Some houses are too tight before any measures are taken and the occupants are happy to know there is a deficit and how to remedy the issue.  An energy audit consistently delivers the options for solutions which gives the homeowner complete control.

What does a BGE Energy Audit Look for on the Exterior of Your Home?

BGE Energy Audit Exterior InspectionA walk around the perimeter of your home by a certified auditor is an important part of taking a whole house approach to remodeling.  Uncovering issues that have gone unnoticed is an effective way to prioritize your home remodeling projects. 

For example, if there is a leak in the roof then it would not be wise to install attic insulation.  Damage to the insulation can occur if water is infiltrating into the attic.

Other areas of importance are drainage around your home, land grading, foundation type and condition, siding, windows, doors, HVAC and trim.  Looking at ventilation areas on the outside of the home will also help to prioritize your next home improvement projects.


How to Prepare for a BGE Energy Audit?

Pointing out comfort issues or other concerns to your technician is an important part of the audit. This way proper time will be set aside to investigate your specific concerns.

Here are the ways you can prepare and get the most out of your audit:

  • Write down any comfort issues by season
  • List any smells around the house you might have noticed
  • Think about any changes to insulation you have made since living in the home
  • Find out the age of your HVAC equipment
  • If you have a wood burning fireplace, clean out the ashes before the BGE energy audit
  • Get a copy of your BGE energy bill for the audit
  • Carve out about four hours of your time to have the audit performed
  • Clear any entrances to the attic, crawl space or other area that might need insulation and is hard to accessPreplist for BGE Energy Audit

What Can You Expect from a BGE Energy Audit?

If you had an audit through the program or plan to get one, you should be able to identify with several if not all of the following take-aways:

  • Your technician explained the BGE energy audit process
  • You will know how much insulation you have and how much you need
  • The technician answered all of your questionsBGE Energy Audit Blower Door Test
  • The technician showed you something that you did not realize about your home
  • Parts of the BGE energy audit were interactive
  • You part ways with your auditor feeling smarter about energy waste and more in control
  • A clear priority list begins to emerge with both wants and needs addressed
  • At least one do-it-yourself tip that will make an immediate impact on your energy usage/comfort
  • You remember the blower door test!
  • You felt a leakage point somewhere inside your house
  • Your home was left in the same way it was prior to the energy audit!

These are all signs that you have had an excellent BGE energy audit!
 

Who is Eligible for a BGE Energy Audit?

bge home inspectionIn order to qualify for a BGE energy audit, you must be receiving electric and/or natural gas service from BGE. 

The offer is not valid for new construction, multi-family dwellings or commercial buildings.  The special $100 fee for the audit is also only valid for your first audit under your BGE account at a specific address.


How to Participate in the BGE Energy Audit Program?

According to BGE the first step to get an energy audit is to select a participating contractor. You can schedule a comprehensive home energy audit with Hometrust here. The cost is $100 ($400 value).

Once the BGE energy audit is complete your home's data will get entered into the modeling software. The program calculates eligible rebates. It also calculates how much energy you can save if you get the work done as prescribed.

Incentives and Rebates Connected to the BGE Energy Audit

Are you are having a specific comfort or energy usage issue? Are you in the market for insulation, efficient windows and doors, a new water heater or new HVAC?

If you said yes, then the BGE energy audit program is an absolute no-brainer for you. Here is what the incentives cover in the way of high efficiency products and solutions:

  • Air Sealing and insulation
  • Heating and cooling equipment
  • ENERGY STAR® Windows and Doors
  • Hybrid heat pump water heaters
  • Duct Sealing
  • Smart Thermostats


BGE Energy Audit Instant Savings Measures

  • High efficiency LED light bulbs
  • Low-flow shower head fixtures
  • Low-flow sink aerators
  • Insulation for hot water heater pipe

Who is Qualified to Perform a BGE Energy Audit?

There are only a select few contractors in the state of Maryland that qualify to perform a BGE energy audit. An approved auditing company in the program has a very unique skill set.

There are two unique certifications that are critical to understanding the audit process and being accepted into the program. A contractor that carries a Building Analyst certification can identify energy issues. The Envelope Professional designation means that we also know how to fix problems.

Most contractors know how to sell you what you want and install what they sell. BGE energy audit approved energy firms know how to show you what you need and install it so it makes a difference.


Can a BGE Energy Audit Help Me Find Ways to Reduce Insects/Rodents In My Home?

An energy audit has one main purpose and that is to tighten the envelope of your home. This means to let less air leak in or out. Insects travel in and out through the exact same pathways.

The answer is yes! An BGE energy audit will look around your entire home to search for air leakage. When you take advantage of the available incentives to get the work done it will also help to reduce pests.


Will the results of a BGE energy audit save you money?

BGE Energy Audit

A comprehensive energy assessment through BGE will save you money - no questions asked! Upon completion of your initial inspection, the auditor will install energy saving measures. This will help you save right away!

On a grander scale, the answer gets more complicated. There are many factors that must be in the equation to determine an answer.

For example:

  • How long will you live in the home?
  • How much work does the home need?
  • What type of fuel do you use for heating and cooling?

A BGE energy audit is the absolute best way to figure out the answer to the question. In fact, that is the design of the program. The audit is the analyzation step. Information obtained during the audit can set a pathway to comfort and efficiency.


What Types of Recommendations Come Out of a BGE Energy Audit?

If you believe that improving comfort and efficiency is as simple as replacing windows or adding insulation to what you have then a BGE energy audit is something you should strongly consider.

A typical prescription for tightening up a house and making it more efficient will include things like caulking, air sealing and weatherization treatment to the attic hatch.  Walls that are accessible in the attic (kneewalls) may be recommended for treatment and the basement rim joist is a big opportunity in unfinished areas.

Each home is different and the "low hanging fruit" are different for each home.  A good energy auditor will find differences in the same model in the same neighborhood.  The audit takes a snapshot of your home's insulation levels around the house, reports on them and makes recommendations on how to improve the boundary locations.

Conclusion

Residential homes and commercial buildings account for approximately 39 percent of total U.S. energy consumption. 

Energy consumption within a building is made up of many parts and the building envelope is the single biggest factor in what part of the usage is waste.  The envelope serves as the barrier between the inside and outside. 

A BGE energy audit evaluates your home's envelope and looks for easy ways to tighten things up.  A BGE energy audit can lead to more home comfort and smaller energy bills.
