Having a municipal utility in town, Wellesley is better positioned than other communities to transition to clean electricity. Two thirds of the Town of Wellesley's energy is from non-emitting sources, making moving to electric in our community, the healthy way to go.

Transitioning away from gas is critical to meet the Town's, State's and Federal emissions reduction goals.

Please try something new and do better for the next generation. 

ANother Net Zero Home

4/19/2024

Thanks Green Needham for this story!

Right down the street in Needham there is another example of net energy home. These super energy efficient houses generate enough solar power to provide all the electricity needed for the home’s heating, cooling, hot water, cooking, and other electrical systems.  

Green Needham has already profiled one family’s process of deciding to build a zero net energy home and condo neighbors who retrofitted their 1860-sq.-ft units to drastically reduce the carbon footprints. Now let’s take a look at another Needham home and learn more about the building techniques that create a home with no carbon emissions and no utility bills. 

The construction of this home, which uses the most energy-efficient technology currently available, differs from traditional construction methods in several important ways.

It’s all in the envelope! The builder is paying great attention to the “envelope” of the house, the exterior shell that separates the home from the outside world. Energy efficient houses have tight envelopes to minimize the flow of air and moisture between the home and the outside. When the airflow in and out is minimized, a house needs much less heating and cooling, which saves energy and reduces costs. 
​
To achieve a tight envelope, the builder has created a continuous exterior wrap of foam over the house studs and foundation, to keep heat from migrating through the framing to the outside world. The wall framing uses a special stud called a T-stud. T-studs have spaces in the center to allow spray foam insulation to flow through the stud itself, which further helps to keep heat from leaking to the outside. In addition, the builder has installed triple pane windows that open like casement windows and provide a tight seal when closed.

But won’t the house be too tight? Haven’t we been hearing about the importance of fresh air and ventilation? But no, an envelope cannot be too tight. A home with a tight envelope keeps the air quality healthy using ventilation and air filtration systems. A leaky house allows heat to escape and moisture and air contaminants to enter the home. A tight house manages the flow of air and filters it as it enters the home to ensure that the air is as healthy as possible. 

No fossil fuels! The house is powered entirely by electricity. Most, if not all, of the home’s electricity will come from a rooftop solar system. Because the house has a tight envelope, its energy needs will be modest for its size, and the electricity generated by the solar panels is likely to be sufficient. The home’s HVAC system will be a geothermal heat pump, powered, like the rest of the house, by the solar panels. In a geothermal system, water circulates in underground pipes, capturing the constant temperature of the earth below, and transferring the warmth or cooling to the building. Geothermal is the most efficient HVAC system currently available, and it has the lowest carbon footprint of any HVAC system.

Energy Efficient Details. Finally, the home has many interior features that will increase its energy efficiency and the comfort of the family members. The house uses radiant floor heat in all living areas and the HVAC system has separate controls for each major room. The interior walls are well-insulated, which keeps the house quiet and allows the family to heat and cool only the areas that are in use. The plumbing drain incorporates a heat exchanger called a Power Pipe. This ingenious device captures some of the heat energy that goes down the drain when you are doing laundry or taking a shower. The captured energy, which is normally wasted, is used to preheat the water flowing into the water heater so the heater doesn’t have to work as hard.

This beautiful home is large, but the same technology can be used in a house of any size. The advanced construction techniques and HVAC system allow any house to use less energy for heating and cooling. And the low energy use makes it much easier, in turn, to install a solar system that is large enough to power the home.

​The upfront costs to build this energy-efficient home are slightly higher than traditional construction, but the additional cost will be recouped over time, as an energy efficient building is economical to run. Think of your monthly utility bills. The goal for this home is to reduce that monthly expense to zero. These technologies are easier to install when a home is first built, but some of them, such as solar panels and electric HVAC systems, can be added during renovations or when systems need to be replaced. Moving toward net-zero housing is beneficial for both the homeowner and the environment!

Major Cost Savings When converTing to electric from oil

4/1/2024

 
Picture
Thank you to Michael M. for sharing his story about converting to electric from oil and the costs savings.

After attending a Town-sponsored webinar on Air Source Heat Pumps (ASHP), we contacted Abode Energy Management to set up a personal Zoom meeting. Abode spoke to us at length about our particular situation: a 100-year-old home with oil heat and radiators, (no ducting or air conditioning), and discussed what solutions might be available to us. 

We did learn that we would need to upgrade our electrical system from a 100 AMP to a 200 AMP service, and we worked with an excavator, an electrician, and the Town to make that happen. This was less complicated than it sounds. 

Abode then directed us to the Town's website for a list of approved vendors for ASHPs, and we contacted two of them. Both came to our home and provided a detailed installation proposal and quote. 

Each vendor proposed unique configurations and different equipment manufacturers. Abode reviewed both proposals to ensure they would be sufficient to heat and cool our home - with no backup system. While Abode deemed both proposals would do the job, they helped us compare them, and even tweaked them, so we felt comfortable moving forward. 

We chose Endless Energy to install an LG system with two heat pumps. Our first floor has ductless floor units, (as we were sensitive to maintaining the character of our home), the second floor is a ducted system with vents in the ceiling and the air handler in the attic. 

Our install was completed in December of 2022. 

We have been very pleased with our conversion to electric from oil. The units are quiet and remote-controllable. Our home maintained a comfortable temperature throughout the past two winters, and it was pure joy to turn on the AC last summer, vs. having to lug heavy, (and noisy and energy-inefficient), window units down from the hot attic. 

Many people had suggested we keep a "back-up" system for cold days, but with our two heat pumps that has not been necessary. After a severe cold spell two winters ago when the temperature dipped below -10 degrees for two nights in a row and we stayed warm, we removed our furnace, oil tank and radiators. (This required us to replace our oil-powered hot water heater with a heat-pump hot water heater. Abode again assisted us, and we decided on a 55-gallon Bradford White model; we've been very pleased with its performance.)

A side benefit of removing the radiators was freeing up lots of floor space in our home. This made a big difference in every room, but especially in our dining room and in a narrow passageway. 

Finally, the cost savings have been even more dramatic than we had planned. Our energy bills are coming in at less than half of what we have been paying, thanks in part to Wellesley's favorable electric rates, and the high cost of oil. We also realized further savings by discontinuing the insurances on the oil tank, the annual furnace maintenance, and annual chimney cleaning. Abode also assisted us in claiming $10,000 in rebates. 

Suffice it to say it was a good installation experience all around thanks to the Town, Abode, and Endless Energy, and it's been a great fossil-free solution for heating and hot water, with the added bonus of air conditioning, for our historic home.

Tax Credits For Home Energy Efficiency upgrades & Renewable Energy Systems

3/11/2024

 
Picture
Important information thanks to DOE office of Energy Efficiency and Renewable Energy

Weekly Energy Saving Tip
If you’re a homeowner with an ongoing list of improvements you plan to make “someday,” get out your lists, because “someday” has arrived!

Tax credits for home energy efficiency upgrades and renewable energy systems can make these improvements more affordable than ever, while adding value, comfort, and efficiency to your home.


If you made any of the eligible improvements to your home in 2023, make sure you claim them on your 2023 taxes. If doing your 2023 taxes has prompted your tax planning for next year, now is the time to review the list of eligible improvements and start planning your strategy.

See the list of available home energy tax credits. As a bonus, many of these will also lower your monthly utilities bills.

Maximize Your Tax Credits
But you don’t have to do it all at once.

Unless you have specific equipment (e.g., heating or cooling) that needs to be replaced immediately, you may want to create a multiyear strategy that:
  • Maximizes total allowable tax credits, which are capped at $3,200 each year.
  • Incorporates credits available through 2032.
  • Allows for continuous improvement to your home’s comfort and efficiency.
  • May be helpful to spread out large investments, such as windows. Be sure to discuss installation costs with your window installer when you consider whether to purchase windows and doors over multiple years.
As an example of a multiyear strategy, you could:
  • In 2024, start with a home energy audit ( tax credit of 30% of cost, up to $150).
  • Then, based on the recommendations from the audit, address your home’s envelope, which is often the first step when making home efficiency improvements. To ensure that your home is as energy-efficient as possible before you invest in new heating or cooling equipment, try replacing (capped at $1,200 per year) your home’s:
    • Insulation ( tax credit of 30% of the cost)
    • Inefficient exterior doors ( 30% of cost, up to $500, or $250 each)
    • Drafty windows ( 30% of cost, up to $600).
  • If you do need to consider replacing your heating, cooling, or water heating system to reach your yearly tax credit maximum of $3,200, you could install:
    • A heat pump or heat pump water heater ( 30% of the cost, up to $2,000)
    • Efficient air conditioner or heating equipment ( 30% of the cost, up to $600)
    • Efficient water heating equipment ( 30% of the cost, up to $600).
  • In 2025, you could continue making home envelope improvements to again reach your cap of the $1,200 home envelope tax credit, again evaluating your home heating, cooling, and water heating needs, and purchasing equipment to maximize your tax credits for the year.
  • In subsequent years, continue making more home energy upgrades, which could include an upgrade to renewable energy, installing:
    • A geothermal heat pump ( 30% of the cost)
    • Solar electric system ( 30% of the cost)
    • A wind turbine, if it makes sense on your property ( 30% of the cost).
  • If you have or are planning to purchase an electric vehicle:
    • First, explore tax credits available for vehicles ( up to $4,000 for used or $7,500 for new)
    • You may want to install a home electric vehicle charger at your home ( 30% of the cost, up to $1,000).
See What Tax Credits You Qualify For
As always, talk to your tax professional and review the IRS website to ensure you have the latest official guidance on tax credits, and review the tax credit requirements for each product carefully before making any purchase.

Why My Neighbors Installed Heat Pumps

2/21/2024

 
Picture
Big thanks to Brian Hodgson - Newton resident & Green Newton board member -  for sharing this story. 

With all of the crazy weather and news of climate change, a lot of people are looking at how they can make an impact. Ensuring our homes have less of a carbon footprint is one of the biggest actions we can take – namely better insulation, using heat pumps, and installing solar panels on the roof. I am in the middle of a project to install geothermal heat pumps in my home, in part because I care deeply about doing something about climate change. (I’ll share some more information on that project in another article.)

I live in a neighborhood of old Victorian homes in Newton, and these older homes certainly present challenges to retrofitting with new technologies. For example, installing air source heat pumps with ducting may require opening up walls, mending old lathe and plaster walls, and pulling out the original heating system with their steam or hot water radiators. However, when I took a walk down my street a couple of weeks ago, I was pleasantly surprised to see that a number of my neighbors had recently installed heat pumps. I was curious as to their motivation: was it driven by a desire to be more climate friendly or were there more practical drivers? To find out, I visited two of my neighbors a couple of weeks ago to ask why.

Tanya and David
For my neighbors Tanya and David, the key driver was comfort in the home and reducing their electric bills. They had lived without central air conditioning for a number of years, but last summer it was almost intolerably hot in their house. The in-window air conditioners they had been using were noisy and the electricity costs were high. When they learned about the incentives from Mass Save, which can be up to $15,000 to put in heat pumps, they realized it would be a fantastic investment– and it would also improve the comfort of their home. Since air source heat pumps work to both heat and cool a home, they would not need a separate air conditioning system. As part of the incentive process, they were required to get a home energy audit and subsequently had to beef up their home’s insulation levels. Though the base estimated cost of insulation was $8000, over $7000 of that was covered by incentives, and their out of pocket cost was reduced to about $1000.

Susan and Michael
The second set of neighbors I visited, Susan and Michael, outlined that they had bought the house a couple of years ago and were looking at a number of ways they could make it more energy efficient. While they wanted to make their house less dependent on fossil fuels, attractive financial incentives and comfort in their home were also key drivers in their decision to install a heat pump. As part of their overall evaluation, they looked at a number of options, including upgrading the windows, adding solar, and installing heat pumps. Upgrading the windows turned out to be quite expensive, especially if they wanted to keep the character of the Victorian home, making them hesitate. At the same time, the old air conditioning system they had inherited was on its last legs and would require a large investment for a new one. Thinking ahead to the future, it made more sense to replace it with a heat pump system that could give them both heating and cooling instead of installing another air conditioning system. This reasoning, plus the great financial incentives, made installing a heat pump a great first step in their overall energy renovation plan.

Comfort and Saving Money are Key Motivators
The $15,000 rebate offered by Mass Save, along with an interest free loan, were critical in getting both families over the hump. Tanya said, “With the interest free loan– we pay $200 a month–it’s almost free money.” In addition, they will also continue to benefit from lower heating and cooling costs through the life of the system.

So, while we all have a desire to make an impact on climate change and reduce our carbon footprint, the more practical needs of comfort and saving money are often the reasons why people make the decision to change to heat pumps. Either way, it’s a win-win for everyone.

Radical Residential Retrofitting

6/15/2023

 
Picture
​What was radical yesterday is reasonable today. Households all across the country are grappling with sudden spikes in energy costs, and a very short window to decarbonize. 

For years, Rachel White (Byggmeister) and Audrey Schulman (HEET) have pioneered brand-new approaches to retrofitting our aging homes. Now these two leading lights will be sharing with us findings they recently presented at Building Energy Boston 2023. White will provide a definitive evaluation of the ‘superinsulation’ mode of retrofit. And Schulman will report on the current status of neighborhood thermal networks, now under construction in many locations. With a flood of federal funding, finding the optimal approach today involves questions not even broached a decade ago, and may not be what we expect. The residential sector must decarbonize at an accelerated rate. 

About the presenters
Rachel White is CEO of Byggmeister Design/Build, a nearly 40 year-old residential remodeling company that is striving to serve as an exemplary steward of homes and to prepare them to meet the challenges of the 21st century. Rachel has been affiliated with Byggmeister since 2008, when she hired the firm to renovate her house. What started as an effort to reduce the energy and carbon footprint of her own home became her life’s work. Prior to joining Byggmeister Rachel taught modern Jewish history to adult learners. She holds a PhD in Religious Studies from Brown University and a BA in Religion from Haverford College.

Audrey Schulman co-founded HEET (Home Energy Efficiency Team) in 2008. A lover of maps, she created the first-in-the-nation statewide zoomable public map of utility-reported gas leaks. Through her co-leadership of the FixOurPipes.org study, she helped municipalities coordinate with utilities to find solutions to fix gas leaks faster and at less expense. She started the Large Volume Leak Study, which discovered a way for gas utilities to identify super-emitting gas leaks and repair them. Together with Zeyneb Magavi, she has developed HEET’s innovative solution to transition gas utilities from gas to networked geothermal, or systems of networked ground source heat pumps. There are several gas utilities now installing thermal networks in Massachusetts and New York.

Have Extra? blankets, sheets, towels, plates, bowls, silverware, small appliances

3/28/2023

 
Picture
Welcome Home, a Newton nonprofit organization, collects and redistributes like-new household items to hundreds of people in need each month with no fees, no forms and no requirements. They strive to provide families experiencing hardship with basic household items they need to live with dignity.  Any items that they cannot use are repurposed or recycled appropriately, thus benefiting the environment.

With a waiting list of almost four months for families who have requested goods, the organization is low on the basics:
  • blankets/sheets (all sizes, especially queen/king)
  • towels (all sizes)
  • plates, bowls, silverware
  • small appliances (coffee pots, blenders, food processors, microwaves)

If you have extras of these items at home, please consider dropping off the items during a drop off shift held 3x per week. The items will be in their new homes by the end of the week, and these days, often by the end of the day. Make an appointment to drop off here. If you do not have a large donation and would prefer to drop them off in Wellesley, a resident is willing to bring 1-2 boxes/bags in for you. Email [email protected] for that information. 

Welcome Home was chosen by the board of Green Newton to receive the 2022 Award in recognition for their work in the community to collect household goods and redistribute them to people in need.

Thinking of remodeling?  Get inspired by the Green Home of the Year!

11/7/2022

 
Picture
Built Environment Plus awarded this home remodeling the Green Home of The Year.
Here is why:
​
The owners of this 1930 home reached out to the designers with a long list of frustrations. Their kitchen was cramped, dark and isolated. The half-bath was tiny and lacked privacy. Insufficient insulation and old, inefficient systems made for hot summers, cold winters, and high utility bills.  While such frustrations are common for owners of older homes, the relationship these owners have with their house is anything but common. The husband’s grandfather was the home’s first owner, and his mother grew up there. He and his wife inherited the house and raised their children there. This family legacy imbued the project with special significance.  

The design team reoriented the kitchen towards the back yard, adding a full glass door and three windows that beckon onto a generous deck. They widened the opening between the kitchen and dining room, eliminating a pinch point and visually connecting the front and back of the house. They addressed the comfort complaints, inefficient systems, and high operating costs with a comprehensive package of insulation, air sealing and HVAC measures. They insulated the basement walls with 2” of closed cell spray foam; dense packed the wall cavities with cellulose; insulated the underside of the roof with 3” of closed cell spray foam followed by 7” of cellulose; reduced air leakage by 58%; and replaced the gas heating and hot water and window air conditioning with ducted heat pumps and a heat pump water heater. 
​

According to the judges, “The project demonstrates the value of preserving the embodied carbon of the home, which might have otherwise been demolished; yet accomplishes substantial energy savings and comfort improvements.  The project preserved the original character of this home as well as its neighborhood and was done affordably.  The judges were impressed with the practical approach that achieved such significant results.”

Electrify Your Home: Webinar 9/28

9/20/2022

 
Picture
Have you thought about ditching gas and electrifying your home, but you aren't sure where to start or how to do it? There are Wellesley, State and Federal incentives and rebates to help.

You are invited to "Electrifying Your Home: how to ditch gas and electrify everything," co-hosted by U.S PIRG Education Fund and Rewiring America, on Wednesday, Sept. 28 at 3:00 p.m. ET/12:00 p.m. PT.

Electrifying your home not only can prevent air pollution, but also helps to avoid the worst impacts of climate change. Electric and induction stoves are efficient replacements for the dirty gas stoves that cause indoor air pollution in our homes, and along with electric space and water heaters, can lower our dependence on fossil fuels and help to power our lives with clean, renewable energy.

At this upcoming webinar, "Electrifying Your Home," they will discuss the benefits of electrification for cooking, home heating/cooling and water heating, and you can get your questions answered by experts and people who have recently made these changes in their own homes. They will also discuss some of the new incentives for consumers that were included in the Inflation Reduction Act.

Insider Scoop: They Renovated & Now Only Pay $10/Month For All Electricity (Car Too!)

7/13/2022

 
Picture
We realize it's the summer and ironically we are talking about ice dams.  Many of us have unfortunately experienced them, including Teri and Jamie Ebersole here in Wellesley. Over the last several years, they did piecemeal projects to protect themselves from recurring ice dam damage. However the dams highlighted to them the increasing severe weather due to climate change. Thus, when they decided to renovate their kitchen, they took a hard look at the resiliency of their home.  In the end, they spent a fair amount of their renovation budget on aspects of their home that will make their family home more resilient.

What does that mean?  Climate resilient buildings are built, or retrofitted, to withstand severe storms and natural disasters. The Ebersoles wanted their 1940 colonial – gone farmhouse – home to withstand extreme weather. They interviewed a few architects and builders and went with Wellesley’s Kraus Associates. After much research, and discussions with Abode and other energy efficiency experts, the Ebersoles now have a beautiful renovated, healthy and resilient home they are proud of.

This all turned out to be a valuable investment as well. The last 2 months they have only paid $10 a month for all of their electric cooking, heating/cooling, driving, laundry needs!
How are they doing this? They moved to electrical, high efficient systems, and fully insulated and weatherized their home:
  • Added insulation to attic; sealed ductwork
  • Removed existing radiators and central air conditioning
  • Installed ducted electric air-source heat pump for the whole house (2 central units that are entirely ducted, 1 that handles the 2nd floor)
  • Exchanged their Viking gas range for an induction stove
  • Exchanged gas dryer for electric dryer
  • Purchased plug-in minivan which they LOVE
  • Installed drip irrigation everywhere possible after construction
  • Installed 12.41 kWh solar system. Although their home was not considered highly solar suitable, it currently covers 98% of their energy use for all of the above so far! Full disclosure, one family member was not really interested in solar during the start of the project but by the end is thrilled with the payback, and is checking the app to see “how much did the solar produce today?”
  • Added a bulkhead for emergency egress from basement 

They still have their gas-fired tankless water heater, since it was newish at the time of renovation, but that is the only gas in their home. They will likely replace it with an electric air-source heat pump water heater at its end of life.  Since they have a family member with lung challenges, they are very happy to minimize the amount of unhealthy natural gas in their home.
“We love our house and want to stay here a long time, so it made sense to make it healthy, resilient and sustainable for the long-term.”

Reduce your Energy Use/Cost...Without Compromising Comfort!

Below are some tips on what you can do: 
Get an Assist from Mother Nature
  • Cross-ventilate – When humidity is not high and air cools down, open all the windows and let cross ventilation cool down the house
  • Capture cool night air – Use window or attic fans to draw in cool air
  • Trap cool air – Close windows before the temperature and humidity rise in the morning, to keep cool night air in the house
  • Seal in cool air – Keep doors, windows, fireplace dampers etc. closed to better hold inside coolness
  • Capitalize on wind chill factor – Use ceiling or portable fans in occupied rooms to reduce the perceived temperature by up to 5 degrees, and set the thermostat higher

Reduce Heat and Humidity Sources in the House on Hot Days
  • Block hot rays of sun - Close curtains, shades or blinds on sunny side of house
  • Reduce sources of heat within the house during hot periods of the day
  • Reduce use of stove, oven, hair dryers, laundry etc. that produce heat
  • Use fewer lights, lower dimmer settings and use cooler light bulbs (CFL’s or LED’s)
where possible

Improve Air Conditioner Management
  • Improve thermostat management
    • Set A/C thermostat at 78 degrees for 18% cost-savings compared to 72 degrees
    • Program thermostat so that maximum cooling occurs when home is occupied
    • Raise the thermostat setting in unoccupied rooms when home
    • Close the register in unoccupied rooms
    • Raise the thermostat setting when traveling or turn off air conditioning altogether
  • Improve Cooling Efficiency with Better Maintenance
    • Place outside condenser in shade, and do not crowd with shrubs
    • Keep air filters clean and have air conditioners serviced annually
    • Maintain ducts and vents, especially the insulation surrounding air ducts passing through the hot attic areas

Unlock $ With Sustainable Energy Investments
• Replace out-dated air conditioners with air source heat pumps
• Install a full-house attic fan and use cool evening air instead of air conditioning
• Install a lighter colored roof and paint the house a lighter color that will reflect rather than absorb the warmth of the sun’s rays
• Plant deciduous shade trees to block summer sun and provide cooling
• Install awnings, shutters or trellises on the sunny side of the house
• Better insulate the attic

Olin College of Engineering and Sustainable Wellesley’s Tiny High Performing Home Wins Chairman's Award During Wellesley’s Annual Parade

5/24/2022

 
Picture
Thanks to the design and construction skills of Olin College of Engineering students Suki Sacks and Daniel Jaramillo, Sustainable Wellesley’s tiny high performing house took home the Chairman’s Award at the Town of Wellesley’s 54th Annual Veterans Parade on Sunday, May 22, 2022.

In March, Suki and Daniel met with us to scope out the building project. The first year Electrical Engineering major and first year Mechanical Engineering major went on to plan and build the home at Olin’s campus with tools on loan from the library and school machine shop with funds donated to support Sustainable Wellesley's efforts. Once the house was built, the Sustainable Wellesley team added some home-like touches and signage. 

Since 63% of Wellesley's emissions come from buildings, this project aimed to educate and encourage residents to take actions that will make their homes more comfortable, less expensive to heat and cool, while helping the Town of Wellesley meet its goal to become Net Zero by 2050. 

Although Suki had returned home to visit family before beginning her internship at VEIR, Daniel was in town for his internship at BAE Systems and decided to join in the parade. 

“Helping Wellesley’s citizens understand the urgency of climate action within their own homes seemed even more pressing with temperatures in the high 90s during the parade,” said Daniel Jaramillo. “The worsening climate affects everyone’s health, resulting in dehydration, heat stroke, asthma, heart disease, Lyme disease, longer allergy seasons, eco anxiety, and much more,” Jaramillo said. 

“We took on this project for the design challenge but also the concern for significant extreme weather impacts that communities face, including wildfires, droughts, floods and more intense hurricane seasons. Creating this house to educate the local community was one way we felt like we could ‘do something’, and we had a lot of fun working on it together!” said Sacks.

The Olin students generously volunteered their time during finals, amid COVID challenges and during dorm move out. This successful student/community collaboration earned the float the “Chairman's Award” during the Veterans Parade that honored Wellesley residents who are recipients of the Purple Heart.

Learn the Benefits of Healthy, High Performing Homes 
Watch recording here
 
Are you considering renovating or building a new home? Here is the recording from our event where local design experts discussed healthy, high performing homes that offer value, comfort, and a way to reduce your emissions.
 
Topics covered in the webinar include:
 
Retaining the Character of Existing Homes
Rachel White, CEO of Byggmeister, a design/build firm, shared 2-3 renovation/retrofit case studies and how they offered significant opportunities to reduce a home’s carbon footprint while improving comfort. 
 
Architect Says: “Designing Net Zero Homes Is A No Brainer” 
Stephanie Horowitz, Managing Director of ZeroEnergy Design, showed a variety of homes, both new construction and major renovations, that offer exceptional energy performance.
 
Building New High Performing Homes
Nick Falkoff, Owner and General Manager of Auburndale Builders, spoke about adjacent cities/towns that are working toward better building practices town-wide, and about effective citizen advocacy.
 
This virtual event supports the Town of Wellesley’s newly launched Climate Action Plan (CAP) which maps out goals and actions residents can take to reduce greenhouse gas (GHG) emissions in our community. As the CAP outlines, in 2020 63.6% of Wellesley’s emissions came from our buildings. By considering and implementing healthy home building practices, residents can help the Town achieve our goals of transitioning away from fossil fuels and achieving net-zero emissions by the year 2050. 

Personal Stories: "How I Made My Home Energy Efficient"

​CREATING A MORE ENERGY-EFFICIENT HOME:
PERSONAL STORIES from Weston, Wayland and Lincoln residents
November 16, 7:00 p.m. via Zoom
Register here

According to the U.S. Department of Energy, more than half of a home’s energy
bill is spent on heating and cooling. A well-insulated home is a surefire way to
help keep your power bill manageable in both winter and summer (if you have
air conditioning). Once a home is insulated, the benefits of other energy-saving
investments, like new heating and cooling systems, grow. And an energy efficient home is not only better for your pocketbook, it’s better for the
environment too!

Three local residents will tell us about their own efforts to drive down fossil fuel
consumption and decarbonize their homes and properties. In each case they
took a systems approach by making several improvements to their houses such
that both their overall CO2 production and energy costs went down.

Register here to hear personal stories from:
Bill Churchill, Lincoln
Sarah Maas Scheuplein, Weston
Roger Wiegand, Wayland
​
This event is brought to us by MetroWest Climate Solutions. This is a growing partnership between First Parish in Wayland, First Parish Church in Weston, First Parish in Lincoln, the Congregational Church of Weston, Sustainable Weston Action Group, and other communities and individuals. Their mission is to share strategies for moving towards a low- and no-carbon-based society and economy and to suggest activities that enable individuals to help bring about solutions.
