Air Quality in the Home: VOCs and Envelopes

Air Quality in the Home: VOCs and Envelopes

Recently, Charles spoke at “Living Well in Your Lifetime Home,” a workshop featuring three certified aging-in-place specialists and industry experts: Charles; Amy Homan Depoy, OT/L, founder and owner of Cardinal Care, LLC; and Gabby Koontz, principal of Rendered Homes. This event was sponsored by VPAS in partnership with Harrisonburg Parks and Recreation. What a wonderful opportunity to share with the community. 

While Charles discussed a wide range of designs and considerations, he highlighted indoor air quality as a very important design consideration for everyone. This is especially true as you age because you can become even more sensitive to poor air quality.

VOCs

There are many considerations when it comes to indoor air quality, and one is VOCs, which are present in all of our homes and potentially hazardous to our health.

VOC stands for Volatile Organic Compound. Many products used in home construction have these chemicals that are released into the air post-installation, called off-gassing. You might be surprised to know that VOCs are in every house and can be found in many common products including paints, lacquers, paint strippers, cleaning supplies, pesticides, building materials, printers, correction fluid, and glues. This is something to be taken seriously. VOCs can trigger asthma, eye irritation, cough, dizziness, and other adverse long-term health effects, and they are known to cause certain cancers. 

 

Envelopes and Energy-Efficiency

Concentrations of VOCs are often found to be higher indoors than outdoors (an obvious conclusion looking at air circulation and volume of space). To compound the problem, the level of these chemicals could even be higher in an energy-efficient’ home that does not have a dedicated fresh air system. 

This is because the more air-tight a building envelope is, the more likely it is energy-efficient. (A building envelope refers to the walls and other materials separating the indoor air from the outdoor air). Creating an airtight home reduces energy leaks at all the gaps and cracks in your home’s walls (around windows and doors, where materials meet, plumbing penetrations, and more). This traps the air inside the home and doesn’t allow in outdoor air. While this prevents energy loss (or gain depending on the season) it also prevents the house from “airing out.” Air pressure around the home and in the home also plays a part in that, but that is for another blog on another day.

 

What should you do?

So what should you do if you want to save money with an energy-efficient home and you want to decrease VOCs and their harmful effects? Is this a catch-22? As scary as this may sound, it is not all doom and gloom, and there are ways to mitigate the amount of VOCs you will come into contact with in your home.

  1. In the construction stage, carefully select products. VOCs can be found in many products including paints, lacquers, paint strippers, cleaning supplies, pesticides, building materials, and glues. We typically select products that have low to No VOCs in them for our clients when possible.
  2. Include a dedicated fresh air system integrated with the heating and cooling system. This will draw in conditioned and filtered air into your home rather than relying on leaks in your home for “fresh” air.
  3. Open your windows occasionally (if your allergies are not too triggered by the pollen levels).

Until products are no longer made with VOCs, these strategies will not eliminate 100% of VOCs, but they will diminish a known health risk to your family. 

7 Summer Energy Saving Tips

7 Summer Energy Saving Tips

The sun is shining down this summer and the weather is heating up out there. I’m suddenly more aware of my AC system… and the large amount of money it might be taking out of my wallet. These 7 tips can help you stay comfortable in the hotter temperatures and save money on your electric bill.

7 Tips to save energy and money:

  1. Adjust your thermostat up a few degrees. This is one we hear a lot. The Department of Energy recommends that you keep the temperature at 78 degrees while people are indoors. It may not be realistic to keep your thermostat set this high for everyone, but try raising the temperature by just a few degrees and see what it feels like. When the temperature inside is close to the outdoor temperature, the less your HVAC system needs to run, saving you money.
  2. Use those curtains! The sun beating through those gorgeous wide windows of yours can create significant heat in your house. On especially sunny days, draw the curtains and pull down the blinds to block the heat.
  3. Let your shrubbery grow. The shade from outside landscaping (or inside, pictured left) can block the sun from sunny windows. Plants who prefer full sun do well on the South-facing side of your house, the side that gets the most sun and heat. Their flourishing growth will block your windows from the hottest direction. Your plants will love you and you will feel more cool!
  4. Replace your HVAC filters. It can take about 2 minutes. Simple as that.
  5. Use a clothesline instead of a dryer.
  6. Take shorter, colder showers to save on the water and electric bill. Better yet, install a low-flow shower head.
  7. Use a ceiling fan instead of turning on the air conditioner. The air moving around the room improves comfort without using a lot of energy.

7 Spring Energy Saving Tips

7 Spring Energy Saving Tips

As Spring sweeps in, temperatures change and your house has different needs. Here are 7 Spring Energy Saving Tips that will help to lower your bills.

 

  1. Utilize Sunlight from Windows: On chillier spring days, save money on heating and lighting. Open the blinds and let that sunlight in in the middle of the day! Be sure to close your insulating curtains before sunset to trap the warmth inside so you don’t lose your gains as the sun sets.
  2. Utilize Window Blinds: Spring in Virginia has temperature ups and downs, so conversely, on hot days, save money on your AC bills by closing the blinds to the windows to block out the heat. Honeycomb blinds work best to stop heat gain into spaces.
  3. Program the Thermostat: On warmer days, set the thermostat higher when you’re gone to save energy. Remember if you have a traditional heat pump, more than a 2 degree change may cause your system to call for emergency heat which is very costly. If you have a newer system that uses a variable speed compressor this is not an issue.
  4. Hang Clothes to Dry: As the temperature warms up, string up a clothesline outdoors to use the sun’s heat instead of the dryer.
  5. Stop hand washing your dishes: Say no more! For larger loads, most modern dishwashers actually use less water. Letting dishes air dry can save more money and electricity.
  6. Replace your HVAC Filters on a regular basis: bonus points for having a performance contract with your HVAC company to make sure your system is running in perfect order.
  7. Assess your home: Check on air leaks, windows, insulation, water, etc. Read more about 5 things you can do for a spring house assessment here.

#EcoFriendly product round up!

#EcoFriendly product round up!

Choosing to live a more sustainable lifestyle can start by swapping out some of our everyday items for more eco-friendly options. We surveyed our team as to which are some of their go-to products they use in their own homes that help reduce their footprint. Check out this list and see if any of these items can be swapped out in your household!

  1. Stasher reusable silicone bags. A few of us use these great reusable bags for our snacks and small travel items instead of regular disposable bags.
  2. E cloth cleaners. Use these washable micro-fiber cloths for numerous cleaning surfaces around the house and ditch the disposable ones.
  3. Wool dryer balls. These eco-friendly dryer balls are a go-to product and are a great alternative to traditional dryer sheets.
  4. Nuuly clothing rental. This has been a fun new venture for Annie who appreciates the concept of reducing waste by renting different styles of clothes each month.
  5. Reusable Grocery bags and crates: A few of us try to make it a habit of keeping reusable bags in our vehicles so we always have them available. Cut down on using plastic bags and grab a few the next time you are checking out! Collapsible crates are also a helpful option to load heavier items without using extra plastic bags.
  6. Quality Reusable Water Bottles: when we aren’t guzzling down coffee, many of us have invested in insulated water bottles that cut down on single-use plastic water bottles.
  7. The best way to cut energy fast is to switch out your old light bulbs to LED. Charles says to use Cree bulbs.
  8. Refillable soap dispensers are a great way to cut down on singe-use plastics. As an additional design tip, look for decorative soap dispensers that coordinate with your bathroom or kitchen aesthetic. Companies such as the Grove Collaborative will deliver refills of your favorite soap and cleaning products to help you cut down on extra packaging.
  9. If a larger swap is possible, considering upgrading your HVAC to a ducted mini-split. Charles recommends this as an everyday item because it consistently keeps his house comfortable! This was an initial investment he made when moving into his older home a couple of years ago.
Taped ducts during construction protect your investment

Taped ducts during construction protect your investment

As we continue to see costs increase for construction it becomes even more important to follow proper protocol during construction. On a recent visit to a job site, I was thrilled to see taped ducts during construction protecting my client’s investment. If the ductwork is left open on the floor and walls then drywall dust and construction debris will fill those ducts, even if the system is not turned on. Then once the HVAC system is turned on dust and dirt will go through the mechanical system and hurt the durability and possibly destroy the brand-new HVAC system.

Seeing the ducts taken care of during construction speaks highly of the HVAC company and contractor and shows they not only understand the installation standards but care about the client. This simple practice does not take much time, but it is often not done. As we continue to see the cost of construction increase, it becomes even more important to protect the systems being installed. So remember: taped ducts during construction protect your investment.
