How Passive Solar Home Designs Can Help Create the Home of the Future

Installing a rooftop solar energy array for an existing home is a great way to save money and protect the environment. That said, energy-efficient home designs can help minimize how much electricity the home needs while integrating efficient appliances, insulation, lighting, HVAC systems, windows, doors, and more!

We’re huge fans of passive solar home designs and other forms of energy-efficient new-home construction projects, as they can maximize a solar energy system’s output by integrating solar features throughout the home. Let’s discuss the various aspects of solar energy design for home construction and renovation. How can these passive solar home design plans save you money while generating eco-friendly energy?

Home Energy Assessments

Home energy assessments are a great way to analyze an existing home’s potential for energy efficiency. If you’re considering installing a rooftop solar energy array, you should first perform a home energy assessment. While you can DIY this assessment, we always prefer hiring a professional.

In your home energy assessment, your chosen assessor will examine each room in your home, using tools like infrared cameras, smoke pens, moisture meters, blower doors, gas leak detectors, and carbon monoxide detectors to identify any “soft spots” in its energy efficiency. Identifying these problem areas can help you make energy-saving renovations to your home.

Smart Design for Energy-Efficient Homes

For new construction, energy efficiency begins with smart design. When planning and integrating solar energy design for home construction, everyone needs to be on the same page. This means that the architects, builders, construction crew, and homebuyers all need to understand their role in creating an energy-efficient home.

Regular communication between all parties is vital when implementing energy-efficient home designs. For instance, if your architect changes their plans, they need to immediately inform the homeowner, builder, and subcontractors to ensure that everyone knows their roles and responsibilities at all times.

What Are Passive Solar Home Designs and How Do They Work?

Passive solar home design plans have become increasingly popular over the years. The most basic definition of passive solar is that, as the home soaks up direct sunlight through south-facing windows, various elements of the home trap and retain that heat, significantly reducing the amount of energy required to heat the home. There are four key elements of passive solar home designs that we will briefly outline before moving on.

Window Orientation

The most important element of passive solar home designs is window orientation. You should integrate as many south-facing windows as possible in the design, and you should ensure that these windows are not shaded during peak sunlight hours. However, it’s also important to install shades and curtains that can block out as much of this sunlight as possible in the summer, when heat becomes an efficient home’s enemy rather than its friend.

Thermal Mass Materials

Passive solar home design plans also include materials that can store heat. In the winter, these materials can trap heat from sunlight within the home, while in the summer, they can cool the air by absorbing heat. Structural materials that have strong thermal mass ratings include concrete, stone, and brick, while decorative elements like tiling and even landscaping can also have an impact.

Distribution Mechanisms

The next aspect is to include elements into the energy-efficient home designs that can spread the solar heat around the house. The means to distribute this heat are conduction, convection, and radiation. Conduction refers to heat transfer between two items that touch each other, while convection is the transfer of heat through liquid or air.

Finally, radiation is the distribution of heat from a nearby source. It’s important for your home’s architect to incorporate elements for all three types of heat distribution in order to achieve success with your passive solar home design plans.

Control Elements

Control elements are the other vital aspect of passive solar home designs. This term refers to things like roof overhangs and awnings for shade in the summer, differential thermostats to control airflow throughout the home, and various elements like vents, dampers, shutters, blinds, and more.

What Is an Ultra-Efficient Home?

The pinnacle of energy-efficient home designs is the ultra-efficient home. This type of home incorporates efficient construction materials and home appliances with a renewable energy system like a rooftop solar array. An ultra-efficient home can even include energy-efficient landscaping and air-tight structural elements. The ultimate in ultra-efficient homes is the Passive House, a certification given only to homes that pass the Passive House Alliance’s stringent requirements for passive solar home designs.

Direct Gain vs. Indirect Gain vs. Isolated Gain

There are three different types of strategies for implementation of passive solar home design plans: direct gain, indirect gain, and isolated gain. Direct gain refers to the living space itself and includes elements like south-facing windows, floors and walls made with masonry, water elements to store heat, and more.

Meanwhile, indirect gain refers to the thermal mass that exists in between the sun’s rays and the home’s living space. A good example of indirect gain is a Trombe wall, a masonry wall usually about a foot thick that sits directly behind the home’s south-facing windows. When the sun’s rays pass through the windows, their energy is absorbed by the Trombe wall and radiated into the home.

Finally, isolated gain is the process of absorbing solar radiation to generate heat. Isolated gain involves a collector mechanism to absorb the radiation, a storage element, and a distribution mechanism.

Other Elements of Energy-Efficient Home Designs

There are other factors in solar energy design for home applications, such as sunrooms made of glass to refract and absorb heat. In addition, energy-efficient window coverings (like blackout curtains or external shutters) can make any home far more efficient in the hot summer months.

Popular Solar Incentive Programs You Should Know About

When it comes to determining how much money you can save by installing solar panels for your home, one of the crucial factors is which government solar energy incentive programs you have access to. Each state has its own rules and regulations for residential solar systems — for instance, California solar incentives differ from Florida solar incentives. Depending on which solar incentives you use, you can save even more money with a home solar system installation than you might think!

To help you understand the different programs available across the country, we narrowed down the list of solar energy incentive programs to the top handful that you should know about before installing your own solar panels. Let’s take a look at each of these valuable programs and discuss how they can make solar energy even more affordable.

Residential Renewable Energy Tax Credit

First up is the Residential Renewable Energy Tax Credit, as described in the Consolidated Appropriations Act of 2021. This incentive provides tax credits for solar energy systems, as well as fuel cells, geothermal heat pumps, and small-scale wind turbines. As one of the most popular federal residential solar incentives in existence today, this program provides a 26% tax credit for all solar energy systems installed before January 1, 2023. For systems placed in service after that date, homeowners still receive a 22% credit. Homeowners are eligible for this program whether they live in pre-existing homes or newly constructed houses, and the program applies to both first and second homes.

Solar Renewable Energy Certificate (SREC)

Another popular solar incentive is the Solar Renewable Energy Certificate (SREC) program, which allows homeowners to sell energy to their utility provider in the form of certificates. Each certificate represents 1,000 kilowatt-hours, and their value can exceed $300 in some areas. Currently, more than half of all U.S. states have SREC programs, although not all of them are considered to be “active” markets, meaning that some states are no longer accepting applications.

Performance-Based Incentive (PBI)

A somewhat similar program is the performance-based incentive or PBI. These solar incentives provide homeowners with payment based on how much energy their residential solar power systems generate. Typically, PBIs are paid out on a monthly or yearly basis over a predetermined amount of time (in California, for example, incentives are paid over five-year periods) at a set dollar-per-kWh ratio. Because these solar energy incentive programs pay based on a system’s actual output, they encourage homeowners to maintain their systems in prime condition, as systems with subpar energy generation are not incentivized as much.

Subsidized Solar Loans

Subsidized solar loans have gained in popularity in recent years, as homeowners look for alternatives to solar lease agreements and up-front cash purchases. These solar incentives are quite similar to typical home improvement loans, with one major caveat: a solar loan not only increases the value of your home (much like a newly remodeled bathroom or a new wraparound porch), but it also generates energy, which puts money directly into your pocket. In this way, subsidized solar loans are truly the best of both worlds.

Solar Rebates by State

Next, let’s briefly discuss solar rebates by state. While we’re not going to run down each and every rebate available on a state-specific basis in the United States, we will quickly touch on a few of them, starting with California solar incentives. This is one of the most popular states for residential solar systems, and a quick look at the state’s solar energy incentive programs illustrates why.

California offers a statewide net metering policy to help homeowners save money by selling their excess energy back into the grid. In addition, the state provides residents with Property Assessed Clean Energy (PACE) financing, which helps homeowners pay for energy-efficient home upgrades, such as solar panel installations. If that’s not enough, California also provides property tax exemptions for residential solar energy systems, exempting the entire value of the solar system from the owner’s property tax responsibilities.

How about Florida solar incentives? While residential solar systems aren’t quite as popular in this sunny state as they are in the similarly cloud-free California, Florida has some intriguing government solar energy incentive programs of its own. For instance, Florida has a similar net metering policy to California’s, and it also provides homeowners with exemptions for both property taxes and sales taxes. This makes solar installations cheaper up-front and into the future.

Texas solar incentives are another interesting case study. The only statewide solar incentive in this state is a property tax exemption. However, that doesn’t mean you can’t take advantage of any other government solar energy incentive programs. That’s because several of the state’s largest municipalities — including Austin, Dallas, and San Antonio — offer solar rebates to help homeowners deal with the up-front costs of residential solar energy system installations.

As you can see, there are quite a few different solar incentives available to homeowners today. While some of them can be accessed on a nationwide basis, some others are only available on a state-specific basis. This is just one of the many reasons that you should partner with a reputable solar installation company like LGCY Power.
