Reduce Your Carbon Footprint Simply by Updating Your Fireplace

The typical American household produces a carbon footprint of an estimated 48 tons per year— approximately doubling the global average. We are a nation in need of an environmental makeover, starting in the home.

Lowing your carbon footprint may seem like a daunting task, seeing that humans themselves are made up of carbon. Many may wonder how they can reduce their household’s carbon footprint without sacrificing their entire lifestyle.  One relatively simple way to lower your carbon footprint, as well as make your home more environmentally friendly, is to start with your fireplace.

Gas Log Systems versus Wood Burning: A Question of Efficiency

The Environmental Protection Agency (EPA) claims that America has more than 12 million wood stoves and fireplaces in homes present-day, 9 million of them being outdated and not up to the EPA’s standards. These burn at a rate that’s 50% less efficient than updated systems.

Thus, gas-burning fireplaces are largely more environmentally friendly and more efficient than their older, wood-burning counterparts. The EPA also claims that replacing your older fireplace will cut your need for wood by two-thirds, which effectively saves you a lot of time, money, fuel, and resources.

Emissions

Your car isn’t the only thing that has emissions—fireplaces have emissions as well.  While both wood and gas-burning fireplaces release emissions into the air, gas systems do so in a massively less significant portion. It’s been found that natural gas fireplace systems can have much less of an impact than wood— with 99% less pollutants. This huge cutback in emissions means your gas-burning fireplace will produce less unhealthy pollution in your home, as well as outdoors. It will also cut Creosote build up in your chimney, which is a highly flammable byproduct of burning wood in your fireplace; not to mention that you’ll no longer have to deal with pesky soot or ashes. A good rule of thumb is: the lower the emissions, the higher the efficiency.

Health Benefits

Not only does replacing your wood burning fireplace with a gas burning one reduce your carbon footprint, but it can also reduce health risks. A gas burning fireplace will naturally reduce wood smoke pollution, which has been linked to cancer, asthma, and a slew of other health issues. This simple change can make a big difference in your family’s health.

Vented and Vent Free Gas Burning Fireplaces

There are two types of gas burning fireplaces: vented and vent free. Each have pros and cons depending on what you’re seeking for your household. Venting gas-burning fireplaces, for instance, will expose one to less Carbon Monoxide (CO) and Volatile Organic Compounds (VOC), but they do not produce as much heat as vent-free systems, nor or they as efficient. Still, both options are considered to be safer and more efficient than older, wood-burning fireplace systems. Regardless of which you chose, fireplace experts suggest installing CO detectors in any gas installation.

Vented or not, replacing your outdated, wood-burning fireplace with a gas-burning system is not only financially savvy, but is also a simple and safe way to:

  • Lower your carbon footprint
  • Reduce the health risks associated with burning wood
  • Bring your home into a more environmentally-friendly and efficient way of life

Thus, hopefully you’ll stop to consider how you can make a difference in your own home, simply by reconsidering something as small as your fireplace.

West MI Home Nears Zero Energy – One Thing Missing

We reached back out to Sam Pobst to take a look at his LEED Platinum home and he sent us his latest utility bills of energy use vs energy produced. You can review it here.

What we found was that from Aug 13 – Aug 14 he had roughly used about 3,000 KWHe (heating and cooling) of energy over what he produced.

“In our original energy model we had included a solar hot water collector which we never installed.  This would have generated about 10% of our total energy requirements for the home, and put us slightly energy positive.  I hope to install it one day, but it is not in the budget yet,” says Sam.

We also asked Sam to talk a little bit about the ROI versus a conventional home built in Michigan. He says, “The ROI with all of the technology we implemented I estimate at about seven years.  The PV has a payback of three years largely because of the EARP grant, the tax credit, and my labor to install it.  The cost premium for the Serious 925 windows over a standard Energy Star window is less than two years.”

EARP or Experimental Advanced Renewable Program is a program from consumers energy where homeowner’s and business owners can be selected to receive almost double the going rate for the electricity sold to the grid.

“I have somewhere around $20,000 invested in the insulation and sealing of the building envelope.  I can’t say what the payback on this is because I don’t know what the baseline cost would be for code built construction.  This includes all of the insulation, extra framing, and the extra plywood sheathing.  Assuming a code built home with 2×6 construction, a quarter of the insulation, and OSB sheathing, would cost at least half this much, I estimate that the payback is around ten years for this.  This payback continues for the life of the home which I estimate to be around 200 years if well maintained,” remarks Sam.

Sam’s home was a targeted passive house but he never made it. Below he details how he surpassed some areas of the program but not in others.

He says, “While we did not meet the heat demand requirements, we more than met the air infiltration requirements, and we devastated the actual primary energy demand by over half.”

                                                    Required                  Actual

Heat demand                           4.75                             6.47

Pressure result                         0.6 ACH50                0.44 ACH50

Primary Energy Demand    38 kBTU/ft2yr            17.5 kBTU/ft2yr

“Based on these metrics, and what I heard at the last PH conference, a restructuring of the organizing principles of PH to weigh these three critical PH components to arrive at a score make more sense,” says Sam.
