Buried Ducts

In the Learning Edge Maximizing Performance with Unvented Attics class, we describe several ways to build homes so that the HVAC ducts are "inside conditioned space."

One of these methods, approved by the International Energy Conservation Code (IECC) and also recognized by the US Department of Energy's "Building America Solution Center," is burying ducts in attic insulation.

While the Learning Edge class, IECC and DOE Solution Center are primarily focused on the application of "buried ducts" in the construction of new homes, many people are interested in applying this building practice in their own existing home, to make their HVAC system, and home, more energy efficient.

In this Product Showcase class, we're going to hear from a company that is providing this exact service for existing homes in the Phoenix, Arizona market.

What we'll be covering:

• A refresher on the various ways to build homes so that the HVAC ducts are "inside conditioned space."
• An overview of challenges with locating ducts in hot attics in summer and cold attics in winter.
• Describe the process for burying ducts in attic insulation, primarily for existing homes, but also for new homes.
• Overview of several existing home projects that have had ducts buried in attic insulation, and share the positive results realized by the owners of those homes.
• Discuss tax credits and rebates available for burying ducts in attic insulation.

Windows

People love windows as much as they love being outdoors, which is no coincidence.

Windows allow us to enjoy the outdoors, at least visually, while remaining comfortable inside our homes and other buildings. This is particularly important on bitter cold, snowy days in winter and stifling hot (and humid) days in summer.

While the first glass windows date back to the Roman Empire and the first century, sheet glass for windows as we know them today was not developed until the 11th century in Germany, and flat plate glass in France in the 17th century.

Fine quality glass with little to no visual imperfections was created only in the past 70 years (in 1959) using the "Float Glass Product Method" developed by Sir Alastair Pilkington in England.

With this modernization of the window glass manufacturing process, windows and glass doors have become commonplace, but much more complex and highly engineered products, offered in all sizes and shapes, numbers of panes, frame types and materials, and coatings to make them more energy efficient.

In this class, you will be learning a little about the history of windows, and lot about the current state of the residential window industry from one of the largest residential window companies in the nation.

What we'll be covering:

• Background and history of windows and Avanti Windows and Doors.
• Window basics, including types of windows and glass doors, window frame materials, glass coatings, and multi-pane glass configurations.
• The performance metrics of windows, including U-Value, SHGC, Visible Light, Air Leakage, Depressurization Rating, Sound Transmission Coefficient, and Wildfire requirements.
• The "Avanti Installation Method" (AIM) that delivers higher quality and more consistent window performance for homes.
• A consideration of the future of windows and what's to come.

Guest Speaker:  Mike Siebert

Mike started in the window industry over 40 years ago after leaving the United States Air Force, working with both window manufacturers and dealers since 1982.

Over his long career, Mike has both started and closed window companies, most recently "Avanti 2.0", started in 2014 with the same owner of the original Avanti that he worked with back in the 1980's.

As Vice President of Sales for the newest version of Avanti Windows and Doors, Mike has helped grow the company from a startup with zero sales in 2014, to over $170 million a year in 2023, with a goal of reaching $500 million by 2028.

Mike takes great pride in the leadership and innovations that Avanti has prided itself on both in the past, and especially today.

For example, Avanti was one of the first, if not the first, window manufacturing company in the nation that added window installation as a service, working with the largest production home builders in the nation to reduce window failure issues caused by poor installation practices.

In his spare time, Mike loves riding his motorcycle(s) as often as he can on short trips, long trips, and just riding to the Avanti office.

He enjoys time with his 5 grandchildren doing cook-outs and going to Diamond Backs baseball games.

Geothermal Networks

A recent article headline by the clean energy organization Canary Media declared, "Geothermal is the hottest thing in clean energy," and then explained why.

While geothermal energy currently accounts for only 0.4% of total U.S. electricity generation, "gobsmaking amounts of early-state investment capital," from the federal government and private industry, are being poured into research, development and deployment of new and improving geothermal technologies.

When looked at from the perspective of "heat", geothermal energy is used for much, much more than just generating electricity.

In fact, harnessing the latent energy stored in water on the surface of the Earth and from deep underground dates back thousands of years to ancient civilizations.

In this class, you'll be learning about the basics of geothermal energy, it's benefits and practical uses and applications, and the growing role geothermal energy is playing in the overall "clean energy" mix, including as a part of community scale "thermal energy networks."

What we'll be covering:

• Geothermal as just one of many "renewable energy" resources
• The basic terminology and principles of geothermal energy
• Modern applications of geothermal energy
• Geothermal heat pumps (aka “ground source heat pumps”)
• The benefits of geothermal energy
• Geothermal heat sinks and sources
• Learn what Thermal Energy Network (TENs) are and how they've evolved over the past 150 years

Earth Friendly (EF) Block

The traditional "insulated concrete form" (ICF) wall system most recognizable to the building industry, uses specially shaped expanded polystyrene (EPS) Styrofoam blocks to hold, then insulate, an inner core of concrete and reinforcing steel.

In the 1980's, a variation on the ICF was developed which does not use new Styrofoam, but instead integrates recycled Styrofoam into a concrete mix to make the blocks.

The resulting product became known as "RASTRA Block," which can be easily cut by hand, formed into foundations and walls, then filled with concrete (just like traditional ICFs) to form a very strong, highly fire-resistant, and energy efficient wall system.

In 2006, Earth Friendly Building Materials, LLC redesigned the manufacturing process of the Rastra ICF block, and created a proprietary wall system, Earth Friendly Block (EF Block) which is manufactured in Arizona.

EF Block provides flexibility in design while maximizing strength, durability, thermal performance, and using a remarkable 87% recycled materials, making Earth Friendly Building Materials the number one recycler of Styrofoam in the state of Arizona.

In this class you will learn all about the EF Block wall system, including what it's made of, how it's manufactured and installed, and all the ways the product maximizes strength, durability, energy efficiency, and environmental benefits for buildings.

What we'll be covering:

• History and background of the EF Block ICF wall system.
• Examples of commercial and residential projects that have been built with EF Block.
• An overview of how EF Block is manufactured and the special characteristics of the product that make it highly durable and energy efficient.
• How EF Block buildings are constructed, including in non-linear shapes.
• How electrical and plumbing are integrated into the wall system.
• How to order EF Block for building projects and the estimated costs.

AeroSeal

Lawrence Berkeley National Laboratory, located in the San Francisco Bay area, has been a leading research institute since 1931.

They have directly and indirectly spawned some of the most cutting edge technology in the past 100 years, including carbon-14 dating of organic matter, the lithium ion battery, low-emissivity or "low-E" coatings for windows, and the development of the energy-efficiency standards for EPA's ENERGY STAR HVAC and appliance programs (to name just a few).

In 1994, LBNL received a patent for a unique aerosol-based sealing technology invented by Dr. Mark Modera. It was used to seal leaks in ductwork, but without the human labor required to seal ducts the traditional way, i.e. by hand with mastic.

In 1997, this cutting edge air sealing technology became known as "AeroSeal."  Its application was expanded in 2016 with the invention of "AeroBarrier," used to seal leaks in a building's envelope or shell.

In this class, you will be learning more about the history and best applications for the AeroSeal and AeroBarrier products, as well as which builders are using them to achieve significantly tighter ducts and building envelopes.

What you'll be learning:

• The background and history of AeroSeal.
• The technical details of the AeroSeal sealant and how it's applied.
• Best applications for AeroSeal and AeroBarrier.
• Where AeroSeal products are being installed nationally, and internationally.
• The role that AeroSeal products play in reaching the stringent air tightness standards for building codes and national energy efficiency programs like ENERGY STAR.
• Which home builders and projects are using AeroSeal and AeroBarrier.

In the summer of 2018, Mike and his colleagues saw a demonstration of a new advanced air sealing application, AeroBarrier, and were convinced that this was the positive disruption to advance building techniques that the construction industry needed. 

Mike invested in the AeroBarrier equipment and product and after completing 400+ air sealing projects over the course of just two years, in early 2021 he joined the corporate team at Aeroseal as Lead Applications Engineer.

When he is not focused on AeroBarrier, you can find Mike diving into a woodworking project, flying airplanes, boating, or enjoying time with his wife and two daughters in the woods and lakes of Minnesota

Cool Roof Technologies

The concept of radiative cooling is not new. Thousands of years ago, Persians in the ancient Middle East harnessed the power of "passive radiative cooling" (PRC) to make ice in shallow pools at night when outdoor temperatures never dipped below freezing.

Today, that same phenomenon of physics is being used to keep steel roofed bus shelters 20 to 30 degrees cooler in summertime in Phoenix, Arizona.  It has been commercialized in products that save 2 to 3 times more energy than PV Solar generates.

In this presentation, you will learn exactly how PRC works, where it can be applied in buildings, and also about other amazing feats of physics when thin films are applied to windows and building surfaces, and granules of a variety of colors are engineered to reflect heat.

This Product Showcase may feel like a return to your high school or college chemistry and physics classes, but the knowledge you'll gain will be worth the journey.

What you'll be learning:

• Background information, i.e. the "science," of passive radiative cooling technologies.
• Learn exactly what passive radiative cooling (PRC) is and why it works.
• See experimental results with passive radiant cooling films (PRCFs) that demonstrate how effective they are at making products truly energy efficient.
• Learn about a commercialized PRCF called SkyCool Panel Systems and how it's being brought to market.
• Learn about transparent infrared mirror films and how they are applied to windows and building surfaces to make them more energy efficient.
• See how cool roofing granules are making asphalt shingle roofs more energy efficient in a variety of colors, both light and dark.

PV Solar Fundamentals

The uses for the Sun's energy go by many names, all including the word "solar."  For example, solar hot water heating, or concentrating solar power (CSP) for thermal energy storage., like the Solana CSP facility in Gila Bend, Arizona.

But the "solar" most people think of when they think of "solar panels," is "photovoltaics," or "PV" solar that turns the sun's energy directly into electricity.

In this class, we will be focused on the fundamentals of PV solar, providing a strong foundational understanding of what makes up a "PV solar system," bringing those new to solar up to speed and filling in the gaps for those already familiar with PV solar.

This class will also be setting the stage for a future Product Showcase class focused on Advanced Technologies and what's in-store for the future of PV solar.

What you'll be learning:

• A brief history of photovoltaic solar and current state of PV domestic and international manufacturing
• An overview of the primary components of a PV solar system, including the most common types of panels, racking, and inverters
• A preview of "Advanced Technologies" and Solar Innovations (to be covered in greater depth in a future class)

Insulation Options for Homes - Spray Foam

While spray foam insulation has been available for many years in both the residential and commercial building industries, it wasn't until after the Great Recession that spray foam hit the "mainstream" of the home building market, becoming widely available in production home communities as opposed to just one-off custom home projects.

As more and more builders selected spray foam to insulate their homes, more and more insulation contractors purchased spray foam equipment to take advantage of the growing demand, and the price of foam and it's installation have become more competitive.

Despite it's growing popularity, and wider availability for home buyers, many in the home building industry don't fully understand spray foam insulation, but this class will help to change that!

What you'll be learning:

• What's the difference between "open cell" and "closed cell" foam, and what is the best application for each product?
• Understand the importance of "flame spread" testing for insulation in attics.
• When installed at the roof deck in an attic, will spray foam hide or reveal roof leaks?
• Understand the air and vapor permeability of spray foam insulation.
• What are the real issues with "off-gassing" from spray foam during and after installation?

Load Shifting

What if you could shave significant dollars off your electric bill with just your thermostat, and without buying more energy efficient appliances or upgrading the windows or insulation in your home to make your home more energy efficient?

While I strongly recommend these things, and we work hard to make new buildings and any installed appliances as energy efficient as possible from the start, not everyone can afford new appliances or a new home.

The truth is, those that can least afford these new things, often benefit most from lower monthly expenses... like lower electricity bills.

So, what's the answer?

It's not sexy, and probably sounds pretty boring to most people, but the answer is.... load shifting.

This is a strategy that every homeowner can take advantage of to save money, regardless of your income level, where you live, or the size and dollar value of your home.

In this class, you will learn exactly what load shifting is, how and why it works, and how you can easily take advantage of this relatively simply strategy for saving money on your own electric bill... without upgrading appliances, windows or insulation.

Once you understand it, not only will you want to use load shifting in your own home, we hope that you will share the strategy with your friends, family and also with other homeowners that you build, design, or inspect homes for.

What you'll be learning:

• Changes in energy demand over the past ten years
• The challenges these changes have created for electric utility providers
• The response of electric utility providers to these challenges
• Explain "load shifting," as one particular response
• Review a case study that shows the real-world impact of load shifting on a home
• Information about how you can implement "load shifting" in your own home (and even if you're a renter in an apartment)

Heat Pump Water Heaters

Heat pumps have grown in popularity over the past 50 years, but most people are not aware that the technology is almost 170 years old, invented by Austrian engineer Peter von Rittinger in the 1850's.

While most people think of heat pumps primarily in the home air conditioning and heating context, they are an integral part of many products we use every day in our lives, including the heating and cooling in our cars as well as refrigerators and freezers in our homes, and more recently in water heaters.

In fact, the history of heat pumps used for water heating dates back over 70 years, most famously in an accidental discovery by Robert Webber when experimenting with the deep freezer in the basement of his home in Indiana.

Much has changed in the technology of heat pump water heaters over 70 years, and with new federal tax credits and utility rebates incentivizing home owners and home builders to install heat pump water heaters, demand is expected to grow significantly.

This class will help you to understand how heat pump water heaters work, provide a deep dive into the latest in heat pump water heater technology, and make it clear why you should strongly consider installing one in the homes you design, build and even the one you live in.

What you'll be learning:

• Why hybrid electric heat pump water heaters are significant to the US market
• How heat pump water heaters us the same principles of refrigeration to move heat rather than create heat
• The different types of heat pump water heaters
• The environmental benefits of heat pump water heaters
• The importance of proper site selection to maximize energy savings and home owner satisfaction
• Requirements for proper installation and maintenance

HRV/ERVs

Ventilation in homes is important to maintaining good indoor air quality, and even more important as the International Energy Conservation Code (IECC) and national energy efficiency programs like ENERGY STAR have increased building tightness requirements.

Recognizing this, ENERGY STAR started requiring mechanical ventilation in version 3.0 in 2010 and the IECC adopted a robust ventilation requirement in 2012.

There are a number of ventilation strategies available to home builders, but it is generally agreed that "Heat Recovery Ventilators" and "Energy Recovery Ventilators", also known as "HRVs" and "ERVs", are the very best strategy.

In the coldest climates, the IECC 2021 and energy programs like the US Department of Energy's Zero Energy Ready Home program now require HRV/ERV's.

In this information packed class you will learn why HRV/ERVs are considered "the best" ventilation strategy, why this strategy is required in the coldest climates, and much, much more!

What you'll be learning:

• The most popular ventilation strategies for homes today
• What is a Heat or Energy Recovery Ventilator and how do they work
• Bust the common "myths" about HRV/ERVs, and learn the reasons why you would likely choose one for your own home
• Examples of how HRV/ERVs are typically installed
• Considerations when meeting code and how to ensure improved performance
• Learn about a number of production home communities that have successfully included HRV/ERVs in their design

Since 2008, HercuTech has worked with home builders like Meritage, Mattamy and Woodside to build homes in Arizona and Florida, showcasing the benefits of their highly engineered wall system, including quieter living and lower utility bills for homeowners and shorter construction schedules and higher quality for home builders.

More recently, the HercuTech team has found a niche partnering with contractors like Sodella Construction to build hundreds of homes for the "build to rent" market, with over 1,000 more homes in the pipeline for construction.

In this class you will learn exactly how and why HercuWall is described as "common materials used in extraordinary ways."

What you'll be learning:

• What types of buildings HercuWall can be used for
• The "extraordinary ways" that HercuWall uses concrete, galvanized steel, polyester film coatings, and expanded polystyrene (EPS) foam
• The complete list of benefits for homeowners/tenants living in HercuWall homes, as well as benefits to builders constructing with HercuWall
• Hear the real world experience of a contractor who has built over 500 HercuWall homes, and has a large backlog to build many, many more
• HercuTech's plans for expanding production and product delivery to key markets in the US

Cold Climate Heat Pumps

All signs point to a future where most new homes will be all electric and, indeed, the movement in this direction is already underway.

According to the US Energy Information Administration, the percentage of homes that are all electric has increased from 20% in 2005 to 25% in 2015.

A big driver of this electrification is the growing popularity of "cold climate heat pumps" that deliver indoor heat even when the thermometer drops below zero outside.

In this class you will learn how cold climate heat pumps do this feat of magic, and much more.

What you'll be learning:

• Why the market is now ready for cold climate/variable capacity heat pump technology
• How heat pumps work in general, and "cold climate" heat pumps work in particular
• The distinct advantages of cold climate heat pumps over other forms of heating for buidings
• An overview of design and installation criteria
• Example projects where hundreds of homes at a time are being built with cold climate heat pumps
• Information on how you can design and build your next home with a cold climate heat pump

Structural Insulated Panels (SIPs)

The construction industry continues to face many challenges with maintaining quality in how buildings are assembled, labor shortages, increased material costs, and increasingly stringent and demanding building codes.

Penalized construction has been around for over 75 years, but today more than ever, can play a major role in addressing each of these challenges and, in doing so, move the construction industry to a much higher level of performance.

In this class you will learn how structural insulated panels (SIPs) are a solution to each of the challenges listed above, and much more.

What you'll be learning:

• How SIPs increase quality, with fewer people, at lower costs, both in time and dollars
• How SIPs are manufactured and assembled in the field
• How to run wires and plumbing in SIP walls, roofs and floors
• How to move a project from drawings, to engineering/design, to manufacturing, and finally delivery and product installation
• See examples of successful residential projects the were multiple homes, not just custom one-off homes

Guest Speaker:   Phil Ligon, Premier SIPs

Electric Vehicles & Battery Storage

All major auto manufacturers are moving towards converting their fleets to electric. Understanding the service entrance requirements for different level chargers will help you educate others on the best solution to “future proof” their homes.

In this class, you will learn common levels of EV infrastructure for residential EV charging and what requirements are coming in the next generation of codes and standards.

The Battery Energy Storage Systems (BESS) available for residential use are rapidly expanding. Understanding the basics of how energy storage works is foundational to working with these systems.

Truly understanding what "Thermal Runaway" is, and how to mitigate the potential hazards of certain chemistries used in BESS, is becoming more and more important for builders, designers, and code inspectors.

In this class, we will be reviewing the most recent code developments for safe deployment of these systems. Understanding the "why" of these requirements will provide you the necessary knowledge to stay ahead of others in the quality and safety of the homes you build, design, and inspect.
