“So when I think about a future that is solving climate, I think about raising our quality of life. I think about more inclusive cities with wonderful parks, and it's a fantastic mass transportation that's really considered a luxury good because whether you're the wealthiest person in that city or the poorest, you all want to be on the same subway or the same bus because it's simply the best way to get around and everyone enjoys these types of amenities.There are examples of that all over the world.  We try and bring those to light. And that is my vision for what the future starts to look like.”Josh Dorfman spent time in China in the 1990s, which opened his eyes to  environmental issues and the impact of rapid industrialization and consumerism. When he returned to the U.S. and went through a phase of environmental activism before deciding to focus on shifting consumption towards more sustainable products.  He started an eco-friendly furniture company called VivaVie in 2004, which led to the creation of his "Lazy Environmentalist" media brand.During the pandemic when supply chain issues made it difficult to source sustainable materials for his previous furniture company, he developed Planted - Josh's current carbon-negative building materials company.  They identified fast-growing perennial grass as a potential replacement for traditional lumber and engineered wood products.  They worked to vertically integrate the entire supply chain, from growing the grass to manufacturing the building panels, and partnered with major homebuilder D.R. Horton to secure a large order for their carbon-negative panels.Josh then launched a media company, Supercool, after stepping down as CEO of Planted to focus on sharing stories of climate innovation and solutions.  Supercool aims to highlight commercialized, scalable technologies and initiatives that are improving people's lives while addressing environmental challenges. He shares his vision for a "Supercool future" that involves raising quality of life through inclusive, sustainable cities and infrastructure.

“We’re always inspired by nature and using nature as a starting point. So we can use the most advanced technology whether it’s robotics or parametric design using algorithms, AI.  Regardless of the technologies our goal is to create something that’s beautiful and it’s just works as far as the simplicity.  And there’s kind of a synergy in the work we do.  So we’re hoping to use this advanced technology beautiful forms in the nature and having everything work together really well.”  - Joseph SarfianJoseph Sarafian and Ron Culver, are the founding partners of architectural firm Form Found Design. Joseph has a background in computational design and parametric modeling, while Ron has experience as an architect, contractor, and musician. They met in graduate school and decided to start their firm together, combining their complementary skillsets.Form Found Design has developed several innovative construction techniques, including using robots to cast custom concrete structures and a computational framing system that allows for mass customization without added cost. They have used these methods for projects like a 15-foot tall concrete structure for Amazon, as well as residential homes.In response to recent wildfires, Form Found Design has focused on designing fire-resilient homes using non-combustible materials like metal, insulated panels, and cross-laminated timber. Their goal is to create homes that are more durable, energy-efficient, and sustainable compared to traditional wood-framed construction.The main challenge Form Found Design faces is educating contractors and homeowners about their innovative construction methods. However, they believe the demand is there, as people are increasingly seeking more resilient and sustainable building solutions. Their overall vision is to use advanced technology like robotics and parametric design to create beautiful, nature-inspired architecture that is also highly functional and efficient.@FormFoundDesign

“I think there's a whole new awareness right now after these fires in LA, at least for people who live in California of like, just actually how toxic our whole houses are.  So, you know, the answer for some might be, “oh, I was going to buy a new couch and I'm going to buy a couch that's cotton instead of like plastic,” you know, just smaller things.  And, yeah, the more people that could be building a whole house out of natural materials right now, that's amazing.”  - Sasha RabinSasha Rabin has a long history with natural building, stemming from her father's early interest in straw bale construction in the 1990s. This sparked Sasha's passion, leading her to study environmental design and eventually focus on earthen building methods like cob, adobe, and light straw clay. She founded Earthen Shelter as a platform to teach workshops on these techniques, which she sees as an important part of creating more sustainable and healthy built environments.Sasha discussed the challenges of getting alternative building materials permitted, especially in high-seismic areas. While there are now code appendices for some natural building methods, Sasha and organizations like Quail Springs, where she is involved, have had to do extensive testing and work with local officials to demonstrate the safety and viability of these materials. Looking to the future, Sasha envisions a multi-pronged approach, from simple retrofits using earthen plasters to whole cob or adobe structures, as crucial for rebuilding more resilient communities.

“The secret is cost shifting.  That’s the secret. So we shift the cost from expensive mechanical systems into the quality of the building shell, of the building envelope.  We have what we call a super-insulated building envelope.  We have triple-glazed windows. We have insulated frames.  They get installed in a certain fashion.  And we basically take… we beef up the building envelope.  it’s super-insulated that means insulation is cheap.  Insulation is the cheapest building material on the planet.  It’s much less expensive than batts.  That’s really the issue.” - Joaquin KarJoaquin Karcher is a founder/owner/principal architect for Zero E Design based in Taos, New Mexico.  The discussion centered on Joaquin’s expertise in eco-architecture and his work with Zero E Design, particularly focusing on cold climate architecture in northern New Mexico. Karcher shares his journey from his early passion for eco-architecture in Germany to his current projects, emphasizing the importance of achieving carbon neutrality in buildings by 2030. He highlighted his collaboration with the Navajo tribe to improve housing using local materials and labor, as well as his insights gained from the Passive House Institute in Germany. The conversation also delved into the principles of passive house design, its affordability in California, and the benefits of enhancing building envelopes to create energy-efficient homes.Karcher discussed the resilience of passive houses in extreme weather and fire-prone areas, suggesting specific materials and techniques for safety. Although he has not yet worked on redesigning homes affected by wildfires, he expressed a vision for affordable, resilient zero energy buildings, particularly through offsite construction methods like panelized construction. 

Healthy home supports your health, in my opinion, from the air we’re breathing, the materials around you, it's designed to promote your health and it prioritizes air quality, has items that are made from non-toxic materials, and it actively reduces toxins, you can actively reduce toxins when you have practices that support a healthy home. So all that is also going to be good for the environment typically. - Karen BloomKaren started her career as a consumer protection attorney, fighting against companies that failed to warn consumers about the dangers of chemicals in their products. She later developed a mysterious illness that was eventually diagnosed as Lyme disease and mold toxicity, which made her highly sensitive to chemicals and toxins. This experience inspired her to focus on creating non-toxic living spaces to help others who have been in similar situations.A healthy home supports your health by prioritizing air quality, using non-toxic materials, and actively reducing toxins. While a green home focuses on environmental sustainability, the two concepts don't always fully align. Karen explained how some "green" technologies like LEDs and EMFs can actually be harmful to health, and emphasized the need for solutions that protect both the environment and human health.Karen provided several specific recommendations for creating a healthier home, including using air purifiers, high-quality HVAC filters, natural cleaning products, non-toxic furniture and mattresses, stainless steel or glass food storage containers, and proper ventilation when cooking. She also discussed the importance of being mindful of the products we bring into our homes and their potential impacts.Karen explained that her business, Natural Haven, offers in-home or virtual consultations to assess a client's home and provide customized recommendations for improving indoor air quality and reducing toxin exposure. She also creates educational content and free guides to help people make their homes healthier.When asked about recommendations for protecting against EMF exposure when outside the home, Karen expressed skepticism about the effectiveness of many EMF shielding products on the market, noting that she has tested many and found them to be ineffective. She suggested exploring professional EMF assessments and mitigation strategies instead.

"The fact of the matter is your heating  your home and cooling your home and heating your water are the two biggest loads to your electric bill. They cost the most in in your home.  So this is an opportunity to yes decarbonize and do right for the environment and our grid but also for energy usage.  And the products are there.  There's more and more coming for sure. " - Anita Singha The much anticipated rebate part of the Inflation Reduction Act, HEEHRA, Home Energy Efficiency Rebate program launched in California in November, 2024.  Anita Singha, the Senior Marketing Manager for the Switch Is On, the administrator of the financial incentive programs in California explains how this rebate program works and how to navigate it.   She explains the program provides rebates of up to $8,000 for low-income households (80% or less of area median income) and $4,000 for moderate-income households (80-150% of area median income) to install heat pumps and heat pump water heaters. The rebates are paid directly to the contractor, and consumers must use a HEEHRA-qualified contractor to be eligible. Anita walks through the steps for consumers to verify their income eligibility and find HEER-qualified contractors through the Switch Is On website. This includes using an online income verification tool, getting a certificate of eligibility, and then contacting multiple contractors to get quotes. Izumi shares her experiences trying to help low-income homeowners, particularly those in remote/rural areas, navigate the HEER program. She highlights issues like lack of HEER-qualified contractors in certain regions, contractors being unfamiliar with heat pump technology, and complexities around mobile home and rental properties. Anita acknowledges these challenges and discusses efforts to expand contractor training and outreach, and reassures that the $450 million in HEER funding allocated to California is secure, even with a potential change in federal administration. However, she notes that the rebates may not last indefinitely, so consumers are encouraged to act quickly. Additional clarifications:  California state is launching the rebate program with one appliance at a time, mainly focusing on the heat pump systems.  The first phase was for heat pump HVAC system, in which low-income households can get it installed for free although the homeowners may have to cover a difference if the cost of installation exceeds $8,000.  Qualified householders can apply if you live in a condo, 2-4 units buildings, ADU and Junior ADU.  If you live in a mobile home, you can apply as long as you’re on a foundation and not have an axle or license number. 

We are focused on incentives for home upgrade projects.  We’re focused right now on residential space.  If anyone is listening or you might have applied for a rebate program in the past, like an appliance rebate program through a government agency or utility, it oftentimes can be quite challenging.  So we provide an end to end solution to make it very easy for folks to pre-qualify projects for all available incentives as well as then to claim the funds. And you can think of us as kind of a TurboTax for electrification rebates.  - Aimee Bailey, Rock Rabbit Rock Rabbit was founded in 2022 by Aimee Bailey, co-founder and CEO, with her co-founder,  building on concepts Bailey had been developing for years in her previous roles in the energy sector, including roles at the Department of Energy, utilities, and government agencies, with a focus on designing and deploying incentive programs.  The company's mission is "Future-proofing homes made easy and affordable for everyone," reflecting their commitment to accelerating the energy transition in the residential sector. Rock Rabbit provides an end-to-end solution for contractors and homeowners to easily navigate and claim rebates for home electrification projects. The platform integrates multiple databases, including incentive programs, authority having jurisdiction (AHJ) registries, and community choice aggregation (CCA) information, to simplify the complex landscape of rebates and eligibility requirements. The company addresses three key pain points in the rebate process: incentive discovery (finding available programs among hundreds of options), navigating eligibility requirements (interpreting complex program rules), and streamlining paperwork processing (reducing administrative burden for contractors and homeowners). Rock Rabbit works primarily with contractors as their main user base, but also collaborates with utilities and government agencies to streamline rebate programs. This dual approach allows them to improve the rebate process from both the implementation and administration sides. There's a significant labor shortage in the HVAC industry, with estimates suggesting a gap of hundreds of thousands of technicians needed to meet climate targets. Rock Rabbit aims to alleviate this by making rebate processes more efficient, allowing contractors to focus more on installations and less on paperwork. For inquiries, contact: info@rockrabbit.ai

If you’re thinking about starting an Eco-Village, you wanna know, essentially you want to know what are the issues with soil, with air, with water, in your bio-region, in the ecological region that you live in; what are the relationships that you have with your elected officials that have the power over the area where you want to make this happen; who are your neighbors, and what kind of relationships you have with those neighbors whether they’re rural, farm neighbors, or whether they’re urban neighbors on your block. - Lois Arkin Lois Arkin shares her personal journey, from growing up in a close-knit, nature-filled neighborhood as a child, to moving to California with her husband, studying anthropology, and eventually finding her calling in the cooperative and intentional community movements. This led her to found the Cooperative Resources and Services Project (CRSP) in 1980, which laid the groundwork for the Eco Village LA concept. She explains how she came to the idea of creating an "eco village" - a cooperative, environmentally-focused community - after hosting public forums on different types of cooperatives. She describes the process of acquiring the first Eco Village LA building in the 1980s, and how the community has grown to encompass three buildings and a land trust over the decades. As she outlines, the key criteria that define an eco village, as outlined by early eco village pioneer Robert Gilman - includes being human-scaled, full-featured, closing the waste loop, supporting healthy human development, and being sustainable long-term. She explains how Eco Village LA aims to embody these principles, while also maintaining a diverse community in terms of income, ethnicity, gender, age, and household composition. Lois candidly shares the conflicts and challenges the community has faced over the years, including periods of intense interpersonal tensions. She describes how they eventually implemented a formal conflict resolution process, requiring members to first try to resolve issues one-on-one, and then seek mediation through a community conflict resolution committee if needed. Looking ahead, Lois talks about Eco Village LA's upcoming plans, including creating a pedestrian plaza on their main street, developing an urban farm, and continuing efforts to remove more housing in the surrounding neighborhood from the speculative real estate market. She emphasizes the broader goal of transforming the real estate industry's mindset from "maximum return on investment" to a "fair return on investment" to improve housing affordability and quality of life.

“And what we did was, ‘let’s combine the performance of heat pump, off the shelf heat pump, heat pump water heater, with thermal storage with really really smart controls, and you can reap the benefit of that heat pump by shifting the load to the middle of the day and giving you a heat and hot water whenever you need it.”  - Jane Melia Jane Melia, Co-founder and CEO of Harvest, the smart thermal battery system explains the genesis of Harvest.  She discusses the limitations of traditional heat pump systems and how Harvest combines a heat pump with thermal storage and smart controls to decouple the time when heat is generated from when it is used, allowing the system to take advantage of cheaper, cleaner electricity. Jane provides a detailed overview of how the Harvest system works. It uses a heat pump water heater, a thermal battery (hot water tank), and smart controls to optimize when the heat pump runs to take advantage of renewable energy and off-peak electricity rates, while still providing heating and hot water on demand. Jane discusses the cost of the Harvest system, noting that it is comparable to a median heat pump system but with higher performance. She explains the various incentives and tax credits available, including the 30% federal tax credit, that can make the system cost-competitive with traditional gas heating and water heating. She also discusses Harvest's efforts to work with contractors and property owners to drive broader adoption. Jane and Izumi discuss the future of home heating and cooling, with Jane envisioning a future where thermal storage becomes a standard feature of heat pump systems to better leverage renewable energy and support grid decarbonization. They also discuss the policy changes, such as bans on new gas furnaces, that are helping drive the transition to clean heating solutions. harvest.green

“During Covid I started to think more about the products I was using and plastics.  I’d always used refilled bottles for water and I’d reuse plastic bags at the grocery store.  Then I heard the statistics that 2.5 billion tons of trash are in the landfill just from hand and body lotion alone and hand and body wash… “ - Libby Bourne    Libby Bourne is the store manager for a sustainable store Sun Moon Rain in Santa Monica, offering refillable cleaning and personal care products. The store aims to eliminate single-use plastic and toxins through education. Libby outlined the store's most popular items like refillable dish soap and laundry detergent, appealing for their effectiveness and concentrates reducing plastic use. Customers favor natural deodorants and handwashes for their safe, non-toxic formulas. Libby ensures products meet the store's high standards by checking Environmental Working Group ratings and trusting suppliers with aligned values. This gives customers confidence that items support wellness without compromising the planet.   She explains how the store attracts families seeking non-toxic products plus students and health practitioners concerned with sustainability. Santa Monica schools influence interest, and youth outreach grows demand while older customers remain open to change. While progress encourages Libby, a perfect solution remains distant. Continued education and small individual changes can chip away at plastic pollution if companies also curb production. Collaboration across generations offers hope for positive change.

"We’re not sacrificing anything aesthetic.  We’re not sacrificing anything ergonomic by being mindful.  We’re just pausing and thinking about it and making a good decision instead of rushing through to check everything off the list.  It’s not going to be apparent in the final end result that you did everything in a very sustainable mindful way.  It looks the same.  It functions the same.  It’s just going to last, and it didn’t hurt anyone in the process.  And if it’s ripped out, it’s not going to hurt the earth for getting ripped out." - Ali Davin Ali Davin is a founder of Jute Interior Design, who specializes in sustainable and healthy designs.  Ali's passions for art, antiques, and spatial design led her to study and work in those fields in Italy and the US. Clients regularly sought her design advice beyond individual pieces, inspiring her holistic interior design practice. For her sustainability means prioritizing the earth's and inhabitants' well-being. Ali incorporated sustainability from necessity due to her chemical sensitivities. It involves mindful material selection, waste reduction, and opting out of consumerism through repurposing. Building codes and contractor mindsets don't always support sustainability. Willing contractors make incremental changes, while some reject discussions. Education is key to accepting health risks in building practices. Ali informs clients of sustainable options without pushing agendas. Most clients initially prioritize aesthetics over sustainability. Changing mindsets requires patience, as rushing decisions sacrifices health and environmental impacts. Ali sees growing receptiveness as sustainability connects to individual and planetary well-being. Her dream is working with aligned clients and contractors on thoughtful, waste-reduced projects that minimize footprints. Her book, Live Natural, aims to introduce sustainability gently through beautiful imagery and approachable, bite-sized writing. It encourages absorbing sustainable messages comfortably without sacrificing aesthetics or function.

“You as a consumer, I as a consumer have enormous power to make the transformation that we want to see.  But one of the transformations as a consumer is selecting the right products because the competitor who is not doing the right packaging or the right product is going to see that they’re losing clients to the competitors that are doing more sustainable product, produce and materials, so he’s gonna change. He’s only going to change because us as consumers are driving the change by purchasing the right or the best materials available for us.”  - Denise Braun Denise Braun found her calling for sustainability work after witnessing waste flooding during a storm as a child in Brazil. She was further inspired after reading a book on applying sustainability in businesses while working in human resources. This led her to pursue a career in waste management. Denise founded All About Waste 8 years ago after having a child, encouraged by her husband to start her own business focused solely on zero waste solutions. The firm now provides zero waste certifications and consulting globally to reduce building waste. She leads by example with zero waste practices like composting and using refillable products. She encourages others gently and hosts zero waste children's birthday parties. She also recommends shopping at farmers markets when possible or using services like Imperfect Produce. She also suggests stores like Sprouts for bulk options. In Europe, she noticed less waste from smaller grocery formats and buying daily needs. Her goal is advising political leaders on waste policy.

"For me, mantra in my sort of day-to-day climate work is go for the gigatons. And while as a homeowner, a single homeowner, you can't do that, you can look at your biggest spend. So what are the most gigantic energy sinks in your home? Two-thirds of home energy use is from heating and hot water." - Trent Wolbe Trent Wolbe is currently a VP of marketing for a start-up called, Harvest, but I invited him to be my guest because of his fascinating history and passionate dedication to help this environmental crisis we face.  He recently joined me as a co-chair of the Green Home Committee at USGBC-LA and dove right into actions, which I’m so grateful for.  He shared how watching Ninja Turtle in his youth led him to be who he is today, and how he and his partner built a sustainable ADU in Los Angeles.   A chance sighting of unusual structures revealed Earthships to Trent, inspiring him to study their off-grid design harnessing nature for comfort through materials and thermal gain. And upon building his ADU, he optimized for minimal energy use with a tight envelope, geothermal, solar, battery and heat pumps. He shares lessons from a challenging but educational process.

"For some folks, they become really motivated by the climate crisis. They start to understand that in their family, maybe their single largest source of climate pollution, and it's a big one, is sitting in their closet just heating their water and heating their house, right? So that's some folks are motivated by that, and they want to start finding out what they can do. Other folks maybe don't care about climate at all, but they've got high utility bills, and they want to understand how electrifying their home can actually reduce their utility bills.  This is a common misperception. People think electricity is expensive, and they think it's dirty. Electricity is not dirty in California. Our electricity supply is remarkably clean. …  Also, electricity is not expensive when you do the math right when you compare apples to apples, running your home on electricity and running it on gas. You'll discover that over time, you can save, a typical home will save thousands of dollars over the lifespan of the equipment that we're talking about." - Cooper Marcus, Chief Quitter, Founder Cooper Marcus founded QuitCarbon, which is a platform that makes home electrification easier, cheaper, and better for all with free expert advice, personalized plans, contractor referrals and support through the process to transition homes off fossil fuels.  Chief quitter, founder of QuitCarbon shares how he started this company as he went through a complex process of electrifying his Victorian home in San Francisco. QuitCarbon is free for homeowners and generates revenue through contractor partnerships by connecting them with clients, with the goal of helping millions of homes electrify while educating contractors on the transition. Cooper addressed pushbacks like climate concerns, cost worries and reliability myths, noting solutions like battery backups and that electricity is often cheaper than gas long-term, especially as incentives lower upfront costs. Also QuitCarbon has developed a software that tracks almost 300 ever changing financial incentives available and be able to inform the homeowners the best possible path of electrifying homes.

“…what can we do in terms of water and energy? Something that's super decentralized that doesn't make people compromise. And we started to look at where water is used most within the residential home and 50% of that water use stems from the bathroom. It's quite alarming when you start looking at how much we actually use in terms of water.” - Alisha McFetridge A typical 10-minute shower uses 25 gallons, whereas Rainstick Shower uses under 5 gallons, saving both water and the energy required to heat excess water. Its point-of-use cleaning further reduces costs and environmental impacts. Alisha McFetridge, Co-founder and CEO, detailed Rainstick's recirculation system saves 80% water and energy by reusing shower water up to six times through cleaning and pumping, while maintaining a strong 3 gpm flow. Her background in water management and sustainability led to developing this solution.  She also explained the installation process, maintenance as well as the possible upcoming financial incentives.

“I feel that we have this moral imperative from a business standpoint to preserve our markets. And so, as Realtors, we are advisors.  So we explain to our developers, we explain to our buyers, we explain to our sellers how to transact in a way that is most profitable for them. how the Code of Ethics really demands that we understand the products we sell and that we do a better job of representing these products.”  - Wayne Beals Wayne Beals is a managing broker at Beals Group of Exit Strategies and a fellow Green Realtor in Chicago. Wayne details his upbringing fixing old homes, sparking passion for buildings that led to careers in construction and real estate. Witnessing energy poverty drove focus to efficient housing. He now specializes in all-electric new construction, convinced gas infrastructure worsens problems, developing with partners seeking competitive edge in electrification. While some buyers eagerly seek green, others dismiss features until educated on health, comfort and cost benefits. Appraisals don't recognize value, hindering prices despite certification.  He believes that as advisors, realtors must explain sustainability impacts for clients' long term interests. While some resist, normalizing discussion introduces more to benefits, shifting perceptions over time for future-proofing markets.  Relying on early adopters, realtors can disrupt competitors by demanding high performance standards. Educating all parties grows receptive audiences. With moral duty to steward resources and public health, the industry must integrate sustainability for viable future operations.

"The new thinking is around circularity. The idea of circularity is the circulation of materials at their highest value for the longest period of time.  And when you design with circular systems in mind, you are thinking about the end at the beginning, meaning what's going to happen to this product that we're making? What's going to happen to this house that we're designing at the end of life? Can any of these things be reused again? Can they be made into something else? Can you take and use... send the furniture back to the manufacturer and they'll repair it or even keep it and resell it to somebody else.  There are companies that do that. " - Kathryn Soter About a year ago, I interviewed Katie Story, a founder of Good Future Design Alliance, which she created to educate the professionals in the building and designing industry to reduce the massive waste this industry generates forging a radical new path in the world of design.  The new executive director, Kathryn Soter, gives us the update on the organization’s missions as well as some practical tips when designing, redesigning and renovating homes or even when we need to replace a piece of furniture to help reduce waste.  Construction and demolition waste is a massive problem, with 500 million tons generated annually in the US alone. This is equivalent to 100 Great Pyramids of Giza per year. There are major health impacts from construction waste, including landfill pollution, emissions, and plastic waste. GFDA aims to connect and educate interior designers, architects, contractors, and manufacturers to adopt low-waste practices. Homeowners should plan carefully, salvage and reuse materials, and hire trained professionals to reduce waste. Resources mentioned: Chairish Renovation Angel Rheaply FirstDib

"I think that we will continue to see high performance sustainability at the forefront of innovation. I think it's going to be a slow transition depending on where you are in the world and where you are in the U.S.  So I think we're going to see different rates of adoption. I think all of it is going to become faster as we realize the impacts of climate change. And the same holds true with the other element you mentioned, which is resiliency.  So as the climate continues to warm, storms are going to be more severe. Floods are going to be more severe, droughts will be more severe, hurricanes will be more frequent. And the approach to build buildings and homes that are more resilient to disaster is going to continue to increase.  And I think those two are going to go hand-in-hand." -Todd Usher Todd Usher is the founder and president of Addison Homes in South Carolina.  Todd has been building high performance homes since 2003 when he discovered Earthcraft House certification.   He is passionate about sustainability and building science.  In his presentation, he explains the key elements of a sustainable home including insulated building envelope, air sealing, indoor air quality management, efficient equipment like heat pumps, and smart home technology. He also discusses how site orientation, window placement, roof overhangs, and other passive design strategies are crucial before considering any technology or building techniques.  Conversation further explores how energy efficiency strategies can align with strategies for improved health, comfort and resilience.

“Building science for these principles and tools to measure and test homes and treat them as an interconnected thing so that all the systems work together and you can achieve better results by looking at the house as a system.” - Dan Thomsen Dan Thompson, the owner and founder of Building Doctors, shares his journey from flipping homes to becoming an energy auditor and contractor. He was inspired to enter the green industry after attending a GoGreen Expo and hearing a talk by an environmentalist, leading him to start his own company called Building Doctors. Dan's company, conducts comprehensive energy audits using science-based tools to assess homes' energy efficiency. They provide homeowners with a treatment plan based on the audit results, which includes insulation, HVAC system upgrades, and solar installation, aiming to make homes more comfortable, energy-efficient, and valuable.  Dan serves on the board of Efficiency First California and the steering committee for Tech Clean California, involving in the preparation to roll out the rebate programs being set forth by Inflation Reduction Act.  His passion for improving the energy efficiency of existing homes is palpable. 

There’s been plenty of studies over the years ranging anywhere from half of a percent to 15 percent in value for certifications.  And part of it has to do with the areas, so obviously when you get into areas like parts of Texas and California, Florida, Virginia, we saw value increases partiallybecause I think you have more educated and interested population who cares, and so they bring that value. -Brett Little Brett is the education manager for this non-profit organization, GreenHome Institute, which provides rich sources of educational information and services to empower people to make healthier and more sustainable choices in renovating and constructing the places we live. Brett shares his knowledge and insight into the current green home space; who are participating in the classes and services they offer; how the certifications would help evaluate homes that have implemented sustainability elements while discussing his own journey of certifying his home and how the certification played a role in getting his home evaluated.
