Geothermal Heating and Cooling Can Be Practical and Affordable When Done on a Community Scale

When it comes to “kicking natural gas” and reducing a home’s carbon footprint, geothermal heating & cooling is the “gold standard.” But it’s extremely expensive to implement as a retrofit and still quite expensive on new construction.

My friend, Martin Voelker, a leader with the Colorado Renewable Energy Society, recently replaced his gas forced air heating system with geothermal, and the cost for drilling the 300-foot-deep wells in his backyard was $18,000, which included running the pipes into his house but didn’t include the heat pump itself. Even though such a project would garner a 30% rebate under the Inflation Reduction Act, that’s still a heavy lift for any homeowner.

I know of another home which installed geothermal pipes horizontally in their large backyard at far less cost.

New construction is more affordable, because you can have the wells drilled within the footprint of the future home while it’s still open ground. And if it’s an entire subdivision, such as the Geos Community in Arvada, the cost is reduced because all the wells can be drilled one after the other.

In that scenario, each home still has its own geothermal well, but what if you could drill a geothermal well that was extensive enough to feed multiple heat pumps in multiple buildings?

That was the concept proposed by a group of Harvard students in Ivory Innovation’s annual Hack-A-House competition, for which they won first place in the “Environmental Solutions and Construction Technology” category.

Those Harvard students may have known something the judges didn’t — that Eversource Gas, a Massachusetts utility, had already begun a “networked geothermal” demonstration project 17 miles west in Framingham. That project is featured at www.HEET.org, short for Home Energy Efficiency Team, which in 2017 started promoting the concept of gas utilities delivering 55º water instead of gas to multiple buildings from a grid of geothermal wells. (The above graphic is from their website.) Think of it as a 21st Century version of what Con Edison still does in NYC, which is to deliver steam from its central boilers to local buildings through pipes under Manhattan’s streets. But steam, unlike water, can’t be used in the summer for air conditioning.

A local vendor that I recommend for both geothermal and air source heat pumps is Sensible Heating and Cooling, (720) 876-7166.

How Does Geothermal Work?

Geothermal heating does not require the presence of a thermal feature such as a hot spring. In fact, if you dig down about 10 feet anywhere at our latitude, you’ll find that the soil temperature is about 55ºF year-round. Circulating a fluid through underground piping heats that liquid to 55º so a heat pump can then raise its temperature to 100º or so for heating purposes utilizing either radiant floor heating, baseboards or forced air.

Geothermal is far more efficient than an air-source heat pump system which takes in outdoor air as cold at 10 degrees below zero and works much harder to achieve the desired temperature for heating.

In the summer the 55º fluid from geothermal requires far less energy to be cooled further for air conditioning your home.

Here’s a Guide to the Tax Credits and Rebates Available for Making Your Home More Energy Efficient

Inspired by a recent article in The Washington Post, I’m able to provide you with a simplified guide to the improvements you can make to your home that might earn you a tax credit or other benefit under the Inflation Reduction Act (IRA).

If you are wealthy, some of those IRA benefits may not be available to you, so check with your tax advisor. Even if you don’t qualify for the tax credits or rebates, almost all of the following investments will produce savings down the road as well as being “the right thing to do.”

Heat pumps to replace your HVAC system and water heater are the first and greatest improvement you can make. Unlike gas and resistance-based electric devices, heat pumps move heat, they don’t generate heat. And a heat pump HVAC system uses far less electricity that a baseboard or other electric HVAC system does. The IRA provides for up to $2,000 tax credit for heat pump purchases, with extra benefits for low- and middle-income homeowners. I haven’t used this company yet myself, but you might contact Sensible Heating and Cooling, 720-876-7166, www.SensibleHeat.net, one of those rare vendors who will talk you into a heat pump HVAC system over a traditional one.

Many heat pump systems, including water heaters, are “hybrid,” meaning they have backup gas or electric resistance functions that kick in or can be activated when the heat pump can’t produce the needed heat. For example, a water heater in heat pump mode has a slower recovery than in conventional electric mode, so if you have a big family (or a teenager) you may find that you run out of hot water quickly and it takes longer than you want to reheat the water in the tank. In electric mode, you’ll get the quick hot water recovery you’re used to.

A heat pump HVAC system will probably work just fine without backup so long as you don’t turn down the thermostat too much overnight. Our office is heated solely by heat pump, and we leave it on 70 degrees 24/7, and it’s still way more affordable than the gas forced air furnace it replaced.

Xcel Energy charges commercial customers about $50 per month (that’s $600 per year!) just to have a gas meter before you burn any gas, which contributes greatly to making gas forced air more expensive than heat pump heating. Note: you need to have the gas meter removed, not just stop using gas, to save that $50 per month. Even in a residential application where the monthly meter fee is less, consider replacing all your natural gas appliances (including your fireplace and grill) so you can have the gas meter removed and save that facility charge plus those other gas-related fees that have exploded of late. There are great electric fireplaces on the market, and Rita & I love our electric grill!

Here’s food for thought: If you get rid of gas in your home and have only electric cars in your garage, you’ll never have to worry about your family being killed by carbon monoxide poisoning. In addition to spending less on home energy and fuel for your car(s), the IRA will reward you for every aspect of that conversion! And with enough solar panels on your roof, your home energy bill will be under $10 per month (to remain on the electrical grid), and you’ll pay nothing to fuel your transportation!

Induction stoves to replace gas ranges not only save you money (including an $840 rebate if you qualify based on income) but can improve you family’s health. Despite right-wing raging about this topic, it has been proven statistically that gas cooking has increased asthma cases in children and some adults. (Click here to read a study on this topic.) The rebate is available on non-induction electric stoves, but induction cooking costs less to operate and heats food and water faster. You can dip your toe in this technology by buying a single countertop induction burner for $50 to $70, as I did. You’ll be amazed. Click here to read an article about how chefs have come to prefer induction cooking. As they say, “try it, you’ll like it!”

Electric cars that cost under $55,000 and trucks or SUVs under $80,000 that are assembled in North America qualify for a federal tax credit of up to $7,500 and a Colorado tax credit of $2,000 (without those federal restrictions, which include an income cap of $150,000 single or $300,000 filing jointly). Even the Tesla Model Y’s base price is now below those price limits.

What’s new with the IRA is that you can get a federal tax credit of $4,000 or 30% of the purchase price (whichever is less) of a used EV that is at least 2 years old, has a purchase price under $25,000, and is purchased from a dealer. I have always advised that a used EV is your best buy, because a used EV is as good as a new EV since it has none of those components of a gas-powered car (such as transmission or engine) which may be about to fail. Google “used electric cars” and you’ll see many for sale by dealers. I just ran that search and found 72 EVs under $25,000 on autolist.com alone!

The IRA increased the tax credit on solar panels to 30% for the next 10 years, and, given the steady reduction in the cost of solar over the past two decades, this investment is a no-brainer, assuming you have a roof that’s not shaded by trees. (Ground mounted solar panels is an option if you have a large unshaded backyard area. Otherwise, consider buying solar panels in a “solar garden.”) Xcel Energy allows you to install enough panels to provide up to twice your average usage over the last 12 months, which is great, because that could provide all the electricity you will need for a not-yet-purchased EV or not-yet-electrified heating system.

My advice is to purchase your solar photovoltaic system outright, not lease it or sign up for a Power Purchase Agreement (PPA). When it comes to selling your house, anything other than a system that is seller-owned could complicate the sale. I’m a repeat customer of Golden Solar (303-955-6332), but also like Buglet Solar (303-903-9119). What these companies have in common, and which I think is important, is that they are local family-owned businesses, which I much prefer over a national firm such a Tesla or Sunrun Solar.

One situation in which a Power Purchase Agreement or lease works better is if the customer is a tax-exempt non-profit (which can’t benefit from tax credits).  Golden Solar put a solar array on the roof of a Golden museum doing a PPA that Golden Solar financed, taking the tax credit for it.  The museum pays no more than they were paying Xcel Energy to Golden Solar but will own the system after a few years. If you know of a non-profit that would like to go solar, have them contact Don at Golden Solar.

Improving your home’s insulation should always be the first step in saving money on energy. The IRA provides a 30% tax credit, up to $1,200 annually, for such improvements, specifying $600 for windows and $500 for doors. The gold standard in windows and doors is Alpen High-Performance Products, a Louisville CO company, which made the triple-pane windows we purchased for our South Golden Road office — expensive but worth it in terms of comfort and energy savings. Contact Todd Collins of AE Building Systems, 720-287-4290.

Whole-house energy efficiency retrofits are eligible for a rebate under the IRA, based on proven reduction in your home’s energy costs. Speak with someone from a company like Helio Home, Inc.  (720-460-1260) which covers most aspects of reducing home energy use covered by the IRA, from solar to insulation to appliances. The IRA also provides a $150 rebate on a home energy audit, which is an essential first-step to figuring out the best and most cost-effective efficiency improvements you can make. You can learn more about energy audits at www.REenergizeCO.com.

Buy a new washer and dryer! The new top-loading high-efficiency washers are the best, speaking from personal experience. The washer automatically reduces water consumption based on the size of the load; and a heat-pump electric dryer saves on electricity.

Landscaping, done right, can save on energy and water. Think shade trees and xeriscaping, or installing buffalo grass, which requires little watering or mowing. Call Darwin at Maple Leaf Landscaping, Inc. (720-290-8292), a client of mine, to discuss the possibilities at your house.

If your house doesn’t already have one, a whole-house fan is a great energy saver, allowing you to flush hot daytime air out of your house before activating the A/C when you come home. It can also allow you to leave the A/C off overnight by bringing in cool nighttime air on a quiet, low-speed setting. Whole-house fans cost between $500 and $2,000 installed. They don’t earn their own IRA benefit, but would contribute to the benefit you earn with the whole-house retrofit mentioned above. I am a happy repeat customer of Colorado Home Cooling, now part of Colorado Home Services, 303-986-5764.

Not mentioned in that Washington Post article was daylighting of your home, which is one of my favorite ways to reduce electricity consumption by drawing sunlight into dark interior spaces. I installed Velux sun tunnels in two of my past homes, including in a windowless garage, and in our former office on South Golden Road. For that, I used Mark Lundquist, owner of Design Skylights (303-674-7147).

Here’s More Info on Incentives in the Inflation Reduction Act

John Horst of the National Renewable Energy Lab read last week’s blog post about the Inflation Reduction Act’s impact on the building sector and provided some valuable additional information.

For starters, he made me aware of the White House website, which has a listing of tax credits and grants under the IRA which pertain specifically to each state. Click here to view the IRA tax credits and grants that apply to Colorado. It’s a two-page PDF with paragraphs about those financial incentives plus job creation, manufacturing, cleaner air, rural opportunities and “resilient communities.”

One new incentive that hasn’t gotten a lot of coverage is the $4,000 upfront discount on the purchase of used electric cars and trucks. In the past, there was no incentive for purchasing a used EV, and the $7,500 incentive for a new EV came only as a tax credit on the following year’s tax return.

Making both incentives an “upfront discount” will make both incentives much more attractive and useful to car buyers and will accelerate the adoption of electric vehicles.

John also provided a link to a list of 59 state and federal tax credits (both personal and corporate), loan programs, grant programs, rebate programs, sales tax incentives, regulatory policies, energy standards and more — each with its own link for further information. (The above link gives the information for Zip Code 80401, but you can select a different ZIP Code anywhere in the country on that website.)

Report Details How the Inflation Reduction Act Will Transform the Building Sector

One of the best analyses of the impact of the IRA on sustainability and the mitigation of climate change was released on Aug. 31st by the Rocky Mountain Institute. Below is a graphic from that report summarizing the IRA’s biggest direct impacts. Click here to view the full report.

As reported by Fast Company, the report “finds that the IRA’s main rebates and tax credits could bring electrification and energy-efficiency upgrades to millions of homes. In total, the bill’s new rebates and expansions of existing tax credits will create more than $23 billion in funding to electrify homes, upgrade heating, cooling, and ventilation equipment, and develop entirely new buildings that meet the highest federal standards for efficient energy use.” The IRA provides funds or rebates for:

Electric heat pumps that can both heat and cool your home, which the Department of Energy estimates will save families $500 to $1,000 every year. There’s a rebate of up to $14,000 for installing them.

Induction cooktops, which replace dangerous and health-harming gas stoves that contribute to asthma and other respiratory diseases.

Insulation, windows, doors, and sealing ductwork, which will ensure a home’s heating and cooling systems don’t have to work as hard to keep families comfortable.

Upgraded electrical panels and wiring for homes that have older electrical service.

The tax credits provided for in the IRA are available immediately, but the rebate program will take some time to be implemented, since it requires the creation of rules and forms.
