Glenn Rockman and his longtime partner, Darron Berquist, love many things about their 3,700-square-foot home off Route 9 in Philipstown (shown above): the quiet woods, the modern architecture, the river views. They also love their electric bill: $21.50 a month. The bills could be lower, but Central Hudson requires a basic service charge to be hooked up to the grid. The one time the bill was higher, it was because they had accidentally left the air conditioning on for 10 days while on vacation. The only gas the home uses is propane in a backup generator. This is all possible because Rockman and Berquist live in a certified Passive House, one of a growing number of ultra-efficient homes whose solar panels generate more power than the owners use. Rockman said they are hooked up to Central Hudson only as a precaution; occasionally, on hot days, the 9-kilowatt solar panel doesn't generate enough power to cool the house. But more often, it's sending electricity to Central Hudson and using a net meter to stockpile credits. Rockman expects to soon replace the backup generator with a whole-house battery that can store the excess production. Budget Busters Federal law could raise electricity costs By Brian PJ Cronin If you're considering making your home more energy-efficient, act now. The federal budget bill signed into law by President Donald Trump on July 4 will eliminate tax credits for solar panels, heat pumps, induction stoves, insulation and energy-efficient windows after Dec. 31. It also will eliminate, as of Sept. 30, a tax credit of up to $7,500 for buying or leasing an electric vehicle. The law could lead to higher utility costs because it kills many industry subsidies for wind, solar and large-scale batteries, which made up more than 90 percent of the new energy added to the grid. The REPEAT Project at Princeton University estimates 30 gigawatts that would have been generated by wind and solar annually may be lost. "Renewables are the cheapest source of new electricity generation, with or without the tax credits that the bill phases out," said Amanda Levin, director of policy analysis for the Natural Resources Defense Council. Although the cost of installing solar and batteries has fallen by 90 percent over the past decade, and wind costs have fallen by 70 percent, the bill "will put a damper on new renewable and energy storage investment over the next decade, which is going to mean less new cheap, clean power getting added to the grid, and higher electricity prices," she predicted. At this point, "we can't build enough new fossil plants to fill the void that might be left by killing renewables," she said. Due to supply-chain issues, there's a backlog of up to seven years for natural gas turbines, for example. Gov. Kathy Hochul has announced plans to build more nuclear power plants upstate, but that won't happen immediately: The most recent nuclear plants built in the U.S. were years behind schedule and billions of dollars over budget. "Renewables and storage are the only resources available to be deployed today at reasonable cost," said Levin. "We won't be able to build new, unexpected, unplanned investments in other types of non-clean energy at least until the 2030s." The budget may mean fossil-fuel plants scheduled for retirement will need to stay open. Over the next few decades, electricity demand is expected to increase by 25 percent, primarily due to the growth of data centers. Relief could come at the state level if New York moves forward with a "cap-and-invest" plan, said Kobi Naseck, director of programs and advocacy for NY Renews, a progressive coalition. The program was announced by Hochul in 2023; corporations that produce more pollution than allowed would pay penalties that fund the state's climate plans and rebate checks for consumers. NY Renews forecasts that a cap-and-invest program could produce savings of up to $2,000 a year for households earning less than $200,000 annually. In Cold Spring, Chelsea Moze...

In this episode, we sit down with Harley Truong, the godfather of Passive Houses in Australia, to explore his incredible journey from public servant to sustainability pioneer. Twelve years ago, Harley was working at the Department of Defence in Canberra when he decided he'd had enough of Australia's zero-star energy efficiency housing and drafty homes. We dive into how he took on the ambitious challenge of building his own passive house without ever having stepped foot in one, using research from Germany's Passive House Institute to create what would become a trendsetting masterpiece.We talk about the reality of building without a blueprint and how Harley had to literally rewrite the rules to achieve his vision. His meticulous approach resulted in an astounding 0.1 air changes per hour—and we explore what that actually means and why it matters. The conversation gets really interesting when we discuss how one exceptional house wasn't enough for Harley, leading him to recognise a massive gap in the Australian market and found Logikhaus to import high-performance European windows, essentially becoming both consultant and supplier to help other builders achieve their eco-dreams.Throughout our chat, we explore Harley's bigger vision for the industry and how he's catalysing crucial conversations about providing better, more sustainable housing for all Australians. We discuss his goal of making high-performance windows the norm rather than the exception, and why he believes we're just at the beginning of an inclusive industry revolution. If you're interested in sustainable building, pioneering business moves, or just love hearing about someone who dared to dream bigger, this conversation will inspire you.

In a slight departure from our usual building performance themes joining us for this episode we have Richard Muscat, a man who has experienced the world of investment and tech from a fascinating range of angles and is seeking ways to do things differently.In essence, we're looking at the way venture capital and climatetech are organised in ways that aren't conducive to delivering the impact that's promised. We're not just picking on VCs, we're using them as a means of highlighting a bunch of systemic economic issues—chief among them is how unrealistic goals for growth (in its myriad forms) almost always leads to failed impact. Perversely, it's a bug in the impact investment space that's a feature of the broader investment system.We also get into concepts of degrowth and economic biodiversity.Good Homes Alliance eventLaunch event of our a best practice guide to ‘Water Efficiency and Reuse in Housing' on Thursday 10 July.Notes from the showRichard Muscat on LinkedinThe Untangled websiteRichard's recent LinkedIn post that we mentionThe Project Drawdown websiteHuman flourishing doesn't require perpetual growth; it requires sufficiency, by Jason HickelSmarter Finance 4 EU — the project Jeff's been working on and promoting because green home certification is about not just energy use, or IAQ, etc, but how residents live their lives once they leave the front door i.e. nature + cycling + public transport + climate resilience etc. all matter**SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this, and it's quite a lot of work, so we have to promote the day jobs.Follow us on the Zero Ambitions LinkedIn page (we still don't have a proper website)Jeff and Dan about Zero Ambitions Partners (the consultancy) for help with positioning and communications strategy, customer/user research and engagement strategy, carbon calculations and EPDs – we're up to all sortsSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd Alter's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Retrofit Space, the renovation and retrofit platform for women**END OF SELF-PROMOTING CALLS TO ACTION**

In this episode we're talking about Zero Bills Homes, so we welcome back Nigel Banks, this time accompanied by his Octopus colleague Emma Fletcher*.We're not directly talking Fabric Fifth again but the concept is central to the Octopus zero bills strategy i.e. prioritising decarbonising energy use and reducing the cost of energy use rather than focusing on reducing energy demand through fabric measures. As before, basic fabric standards are required in order to make the proposition financially viable.As you might imagine, Jeff was keen to dig into the technical and performance side, so Nigel explains what's going on in the standard and what they know about how well it's functioning and Emma fills us in on how it's shaping up to evolve into a building standard in its own right. We're particularly keen because—although we might be sceptical, which we discuss—the action that Octopus is initiating will raise standards and will shape expectations that will influence the whole residential construction sector, and could go some way to catalysing the bridging of the skills gap.*She, too, works at Octopus Energy—she is not an actual octopus.Notes from the showNigel Banks on LinkedinEmma Fletcher on LinkedinThe Octopus Zero Bills proposition in their own words The Octopus Tenant Power propositionNigel Banks' addressing the embodied carbon question on LinkedIn Link to The Octopus Energy Tech Summit (23rd June)The Fabric Fifth ZAP episode from last year**SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this, and it's quite a lot of work, so we have to promote the day jobs.Follow us on the Zero Ambitions LinkedIn page (we still don't have a proper website)Jeff and Dan about Zero Ambitions Partners (the consultancy) for help with positioning and communications strategy, customer/user research and engagement strategy, carbon calculations and EPDs – we're up to all sortsSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd Alter's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Retrofit Space, the renovation and retrofit platform for women**END OF SELF-PROMOTING CALLS TO ACTION**

This episode is all about a retrofit programme gone wrong in Preston and the effort required to fix it. It's a story that was covered in the pages of Passive House Plus back in 2018 under the headline "Disastrous Preston retrofit scheme remains unresolved" and until recently we thought it remained unresolved.We're joined by Filipe Amarante and Joanna Curtis to talk about the Preston Retrofit Catastrophe and all the work that National Energy Action has been doing to fix the grotesque damage that was wrought on a community in the 2010s. It's a project that's consumed at least four years and—in truth—will require many more to make good.It's not a hopeless story though. The work NEA has carried out is full of lessons for anyone who works in retrofit to learn. They've taken a worst case scenario—one so bad it's hard to imagine how you could make it any worse—and developed a remediation programme that mitigates the worst of the situation while laying out a best-practice template for how one should approach place-based retrofit programmes.They're also hosting a NEA webinar about the programme on 10 June: sign up here.Notes from the showThe Passive House Plus article: "Disastrous Preston retrofit scheme remains unresolved"Filipe on LinkedInJoanna on LinkedInThe NEA website The NEA's summary report on the project (and video): Warm and Safe Homes in FishwickMore photos of the disaster in "When retrofit goes wrong – lessons from Preston", a presentation by Kate de Selincourt, the writer who brought this story to Jeff's attentionCathy Come Home on IMDBA Taste of Honey on IMDBRiff-Raff on IMDB **SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this, and it's quite a lot of work, so we have to promote the day jobs.Follow us on the Zero Ambitions LinkedIn page (we still don't have a proper website)Jeff and Dan about Zero Ambitions Partners (the consultancy) for help with positioning and communications strategy, customer/user research and engagement strategy, carbon calculations and EPDs – we're up to all sortsSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd Alter's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women**END OF SELF-PROMOTING CALLS TO ACTION**

In this seventh episode of The Reimagine Edit (TRE) series of the Passive House Podcast, host Zack Semke shares selected clips of insights from Jessica Grove Smith (Joint Managing Director of Passive House Institute), Mark Attard, Rainger Pinney, John Loercher, Galen Staengl, Mike Fowler, Cait Eggers, Sean Velez, Nidhi Shaw, and Lloyd Alter.Quotes:"Walking off the ferry in Seattle and ashes falling out of the sky—that changes your perspective. The same thing with the heat dome and with COVID. These events over the last seven to eight years have reshaped how I think and approach design and architecture, and now my focus is on resilience." — Mike Fowler"If you touch any one single component, make sure you go all the way. That's the only way you're going to future-proof your building and have a long-lasting carbon emission impact." — Jessica Grove-Smith"It's very clear that what typologies get built follow where there's grant money. Developers are happy to build anything as long as it comes with a little extra funding—that's a powerful lever we can use to shape the built environment." — Rainger Pinney"In Passive House buildings, humidity changes very slowly. That just observation applies in any climate—you're less affected because the air isn't running through your building like it does in most buildings." — Galen Staengl"We should be retrofitting schools rather than demolishing them. Roofs, windows, and wall cladding can be replaced; we don't need to demolish the whole school to make it better." — Nidhi ShahThe Reimagine Edit is a special series of the Passive House Podcast that shares curated insights from our Experts-In-Residence at the Reimagine Buildings Collective, our membership community of building professionals stepping up to tackle climate change.

Welcome back to Architecture 5 10 20! I'm your host, Guy Geier, Managing Partner of FXCollaborative Architects in New York. My guests for this podcast are pioneers and visionaries shaping the future of the built environment across various disciplines. Join me in exploring their remarkable journeys, discovering how they reach their current heights, and envisioning what lies ahead in the next 5, 10, and 20 years. Listen in as I have a conversation with my colleague Dan Piselli, FXCollaborative Director of Sustainability. We break down what it actually means for architects to commit to sustainability and discuss the state of climate commitments in architecture and beyond. We talk about how firms are measuring up to the AIA 2030 Commitment, the gaps between goals and actual progress, and, of course, what needs to change if we want to hit those looming 2030 and 2040 climate milestones. Dan shares his insights into how sustainability has evolved from a niche interest to a central concern in architecture, as well as why some states and firms seem to be going faster than others in energy efficiency. We also talk about the commitments made by mechanical and structural engineers, contractors, and manufacturers because, after all, sustainability isn't just an architect's responsibility; it's an industry-wide effort. Along the way, we touch on the role of building codes, the impact of energy modeling (or lack thereof), and why some firms are struggling despite their best intentions, and, of course, we confront the big question: are we actually on track to meet net-zero goals, or are we just going through the motions? Dan shows how industry climate commitments help track progress and drive real change, even though there's still a lot of work to do. Moving forward, shifting laws and market trends should keep shaping sustainability efforts, with regeneration and adaptation playing big roles. If you are an architect, engineer, or just someone wondering what real climate action looks like in the world of architecture, then this episode is definitely for you. Time stamps: [02:09] - Dan reveals that his passion for sustainable architecture began in childhood and led him to become FX Collaborative's director of sustainability. [04:36] - The world is far from meeting Paris Climate Agreement targets, with U.S. climate funding looking at setbacks. [07:57] - Dan points out how the AIA 2030 commitment pushes firms to design net-zero buildings. [11:03] - In 2023, 61% of projects used energy models, but they only slightly outperformed non-modeled ones. [13:04] - Various industry commitments focus on carbon reduction. [16:06] - Dan argues that clients increasingly consider firms' climate commitments. [17:42] - Dan explains that, in 2023, 490 companies reported nearly 25,000 projects, with 10% meeting the 80% reduction target. [20:08] - Ruben Hall, a nearly complete Passive House retrofit, exemplifies energy-efficient building conversion in NYC. [23:18] - The 2030 memo outlines project goals, ensuring alignment with the commitment to energy efficiency. [25:44] - Dan explains how daylight dimming systems and LED fixtures enhance energy efficiency. [27:38] - Rapid environmental policy changes such as Local Law 9 stress the need for sustainability strategies focused on the future. [28:58] - Dan argues that the future of sustainability is in regeneration. Links / Resources:Guy Geier Instagram | Twitter Dan's LinkedIn Page
