5 Easy Ways to Increase Energy Efficiency and Save Money

Home losing heat through roof, windows and doorsWith winter approaching, The Green Cocoon has five easy ways that homeowners can use to increase energy efficiency and save money, besides using our fabulous spray foam insulation! As the weather gets cooler, your furnace will start to come on and that means you’ll be using more energy. Consequently, your heating bills will increase. Try these five easy DIY (do-it-yourself) projects to help cut down on energy loss and expenses.

Replace worn weather-stripping around doors and windows

Did you know that worn weather-stripping can create drafts and let cold air in? This puts a high demand on your furnace and takes away your comfort. Replacing it takes little time and is a low-cost, high-impact solution.

Caulk around windows to increase energy efficiency

Cracks and crevices are a source of heat loss. They can also be an entryway for water/moisture, as well as for undesired insects. Preventative maintenance, such as caulking, can improve energy efficiency and prevent costly repairs.

Change your furnace filter

A dirty furnace filter means less efficiency and that costs money! Check your furnace filter monthly and if it’s dirty, change it or have it changed. Moreover, have a technician come in and inspect the entire furnace at least once per year.

Update light bulbs to LEDs to save money

LED is a highly energy efficient lighting technology, and has the potential to fundamentally change the future of lighting in the United States. Residential LEDs—especially ENERGY STAR rated products—use at least 75% less energy, and last 25 times longer than incandescent lighting.1

An automatic thermostat increases energy efficiency and saves money

You can save money and increase energy efficiency on your heating and cooling bills by simply resetting your thermostat when you are asleep or away from home. You can do this automatically without sacrificing comfort by installing an automatic setback or programmable thermostat.

Farmers’ Almanac Says Get Ready for a “Polar Coaster” Winter

Farmers’ Almanac Says Get Ready for a “Polar Coaster” Winter

According to Farmers’ Almanac (Almanac), we are in for a “Polar Coaster” winter. The term was inspired by the ups and downs that are predicted on the thermometer. Consequently, we may not be able to get off “the ride” until April!  Moreover, now is a great time to start thinking about saving money by making your home more energy-efficient with The Green Cocoon’s eco-friendly building insulation.

Saving Money

How do you save money with The Green Cocoon? Let us explain.

In our blog post, “Invest in Insulation,” we analyzed the average heating and electricity bills in Massachusetts (where we are located). Furthermore, we wanted to give our readers an estimate of how much money they would save by investing in insulation. And, the answer is approximately $1,284 annually!

Additionally, here’s what you can do with $1,284:

  1. You can buy an average of three months’ worth of groceries for a family of four.
  2. You and your significant other could take a one-week cruise to the southern Caribbean from Boston.
  3. Fill the gas tank in your car for almost one year. Of course, this depends on car size and miles travelled.
  4. Invest it every year and after 30 years you would have over $100,000!

New Hampshire Known for Crazy Weather

If you live in New Hampshire, you are no stranger to crazy winter weather. According to NOAA’s National Centers for Environmental Information, the coldest temperature on record in New Hampshire  (-50°F) was on January 22, 1885. That was at the summit of Mount Washington. Likewise, many winters in New Hampshire bring snow, rain, ice, and chilly temps, which many of us enjoy! If you are an outdoor enthusiast, it means a lot of exciting outdoor winter activities.

Almanac’s editor Peter Geiger, said “Our extended forecast is calling for yet another freezing, frigid, and frosty winter for two-thirds of the country.” What does that mean for us this winter? We will experience colder than normal temperatures, and significant precipitation.

Use Eco-Friendly Building Insulation

In conclusion, don’t keep throwing your money out the window. The Green Cocoon has eco-friendly building insulation that comes in various forms. Contact us to learn more!

Invest in Insulation

Invest in Insulation


One question we always get asked here at The Green Cocoon is, “What is the R.O.I. (return on investment) on insulation?” Consumers want to know if the upfront cost is worth it and more importantly, how long it takes to see the payback. Let’s break this down and find out!

Energy Costs Analyzed

Energy costs vary per state, and since we are located in Massachusetts, we will use that state. The average winter heating bill for oil (most popular) is about $2,083 per year[i]. The average yearly electric bill is around $1,128[ii], and much higher in the summer months due to the use of air conditioners.  That comes to a moderate total of $3,211 annually.

Some of our customers have seen reductions in their heating and cooling bills of up to 75 percent, but for the sake of this example, let’s just say that by insulating your home you save 40 percent. That is a savings of $1,284 per year! If the average insulation job for a medium-sized home is around $6,000 (give or take a few thousand depending on size and material), it would take just under five years to get the return on your investment. After that, you are pocketing an extra $1,284 per year. Think of all of the things you could do with that money! What does that money equal?

What You Can Do With Savings

Here’s what you can do with $1,284:

  1. You can buy three months’ worth of groceries for a family of four.
  2. You and your significant other could take a one-week cruise to the southern Caribbean from Boston.
  3. Fill the gas tank in your car for almost one year (depending on car size and miles travelled).
  4. Invest it every year and after 30 years you would have over $100,000!

As you can see, insulation is well worth the investment. The question isn’t, “Can I afford it?” The question is, “How can you not?”

If you don’t have the money upfront for insulation, there’s no need to wait to start saving. Ask us about our interest-free financing options.

Hurricane Season Is Upon Us!

The hurricane season in New England is defined as June 1st to November 30th. However, 75% of the 40 tropical systems that have impacted our region in the past century have struck during the months of August and September. The last severe hurricane to hit Massachusetts was Hurricane Bob in August 1991. Bob, a Category 2 Hurricane, with winds between 91 and 110 mph, caused almost $1 billion in damage. Other hurricanes like Eduardo (1996), Bonnie (1998) and Bill (2009), threatened the Bay State, but veered out into the Atlantic as they traveled up the coast (www.mass.gov).

Insulation of the Future: The Green Cocoon Investigates Hemp

Insulation of the Future: The Green Cocoon Investigates Hemp

The United States demand for insulation is estimated to rise 3.7 percent per year to approximately $9.5 billion by 2021.[i] And with so much demand, new types of insulation are being tested for the future. We will focus on one—Hemp.

According to Green Building Advisor, “Two North American companies are producing insulation for residential construction from locally sourced hemp fiber. This gives builders an alternative to fiberglass, plastic foams, and other more conventional materials.”[ii]

Europe Has More Access to Hemp

In Europe, builders have access to hemp insulation, but availability has been limited in the U.S.  Some U.S. builders have toyed with a mix of hemp fibers and lime called “hempcrete.” But, because of U.S. laws, extensive use of industrial hemp has been blocked.

Hemp Batt Wall Insulation

One Canadian company capable of producing threadlike hemp insulation on a commercial scale is Montreal-based MEM Inc.  Not far behind producing hemp fiber insulation is a biomaterials supplier in Louisville, Kentucky, called Sunstrand. And, new on the scene is Nature Fibres, a Canadian company based in Quebec. [iii] The interesting fact about Nature Fibres is they moved into Asbestos, Quebec, to start up their business. The town was named after asbestos because of the former industry in town. But, due to the associated health risks, those manufacturing facilities are closing their doors.

Benefits of Using Hemp

The benefits of using Hemp for insulation are many. It is biodegradable and has a very long service life. “Walls opened up in France 50 years after construction showed hemp insulation looking essentially brand new.”ii Hemp is composed mostly of a natural fiber (88% hemp fiber and 12% polyester fiber) with no chemical binders and no VOC (volatile organic compounds) off-gassing. As a result, it allows water vapor to pass through it. and is naturally repellant to rodents and insects.

It is clear that with all the changes in the market and with regulations, the insulation industry needs to keep up with demand and changing times. The Green Cocoon is a company that looks to help people lower their carbon footprint by increasing their home’s efficiency. We do this while using the greenest products available on the market.

No Fossil Fuels Needed for Newton, Mass. Restoration Project

No Fossil Fuels Needed for Newton, Mass. Restoration Project

Newton, Mass. – The Green Cocoon, Inc. (TGC) was recently awarded an insulation project for a home in Newton, Mass. The original home, built in the early 1900s, is being fully renovated, gutted completely to the studs. Once completed, solar panels will be installed in the home and it will run on 100 percent electricity. Consequently, this house will not use any fossil fuels!

Closed cell spray foam was used on this project, specifically Gaco HFO (hydrofluoroolefin) spray foam. HFO closed cell spray foam is a reformulated version of spray polyurethane foam. But, the reformulated version has only a tiny fraction of the global warming potential of its predecessor.  HFO is a blowing agent and is an essential ingredient in spray foam insulation. It creates the tiny bubbles of trapped gas that slow the movement of heat and make foam such a good insulator with a very high R-value. But the most common blowing agent in spray polyurethane foam today, a hydrofluorocarbon, has a global warming potential (GWP) more than 1,000 times that of carbon dioxide. The newer type of blowing agent has a GWP of 1.[i]

“We have been using an eco-friendly closed cell spray foam for quite some time,” said Candace Lord, Green Cocoon Vice President. “It reduces excess waste and energy consumption in buildings by up to 50 percent while adding rigidity and strength to the structure. The R-value is over 7 per inch, and it has a greater resistance to the leakage of air and water vapor. It is a perfect vapor barrier in both summer and winter.”

The contract was awarded by Essex Restoration, a residential building and remodeling company in Wilmington, Mass. They have been working with TGC for over two years on restoration and renovation projects.
