Efficiency Electrification Embodied carbon
Education Research Advocacy
After earning a B.S. in architecture at Cal Poly, San Luis Obispo, I soon started my own business, Design AVEnues, and designed 100+ home remodels. Along the way I learned a whole lot about residential construction, but there was always something missing – I wanted to work on environmental solutions. So in the early 90s, before green building even had a name, I went back to school and earned an M.Arch. at UC Berkeley, focusing on energy, materials, and housing – the same core passions that drive me today.
Every project I undertake is guided by my quest to find the next big lever that will help shift the building industry, our communities, and our world to a safe, equitable, and sustainable future.

UPDATES
The City of Petaluma, where I live, just declared a shelter crisis. This is in California, the 5th largest economy in the world — and the largest sub-national economy. Petaluma is not unique in having this problem; it’s all but ubiquitous. We’re doing something very wrong, and it’s shameful — but it’s not inevitable. There Read More »
Air conditioning is like a globally addictive drug: the more we use it, the more we need it. Its voracious energy demands contribute to the climate disruption that is heating up the planet. That’s only one of several reasons NOT to turn down your thermostat, if your house isn’t getting as cool as you would Read More »
I always find myself somewhat repelled by the word consumption. My reaction comes from reading novels set in earlier times, when it was used to mean “a wasting disease” (usually tuberculosis). Earlier today I watched two short videos that produced the same reaction. Appropriately enough, they were about consumption as we more currently define it, Read More »
Spring favorites: work and play
PLAYING: I love spring — especially this spring, which has finally arrived, seemingly overnight, after a long, wet, cold winter. I was lucky enough to celebrate it this past weekend with my favorite 6-year-old, teaching him to dye eggs. WORKING: My favorite climate work is developing education and teaching about energy, emissions, and electrification. I Read More »
California’s spate of public safety power shutoffs (PSPSs) last year has inspired a surge of battery sales this year, as the peak fire season approaches. Scientific American reports, “the share of [Sunrun’s] solar customers who are also installing energy storage was more than 60% in the San Francisco Bay Area this spring.” Sheltering in place Read More »
Image via Pexels It’s been a bit more than a year since I posted, and what a year it’s been! Besides all the global madness, I moved last July from Pacifica to Petaluma, California. I love it here and feel a bit like that girl on the swing. Life is good. Notwithstanding — you Read More »

DOE Launches Home Improvement Expert DOE’s Building America program has a new resource called Home Improvement Expert, developed to help homeowners with energy-related home improvements by using 21 individual home improvement checklists. These can be attached Read More »
Induction Cooking Is the Bomb!
I have a kind of strange admission to make, for an eco-freak. I am eagerly awaiting the death of an appliance. Admittedly, this has happened before, but then it was an aesthetic issue. This time it’s about climate change. I want to ‘decarbonize’ my home — eliminate all sources of fossil fuel combustion so that Read More »

Climate change activism is for EVERYONE
Climate Change, by Sally Deng | via New York Times “We All Must Act on Climate Change.” John Kerry’s opinion piece in the New York Times yesterday is SO right on! My research over the past three years in support of the Net Zero Energy Coalition’s residential zero-energy inventory has revealed a virtuous circle. Geographic ‘hot spots’ Read More »
I’ve been talking to a lot of people lately about electrifying — that is, building an all-electric new home or eliminating natural gas and propane appliances in their existing homes. That’s something I plan to do myself any day now! Meanwhile, for those building new or buying new appliances, I encourage choosing electric options. In case Read More »
Ha! Got you, didn’t I?! The real story is about the progress we’re making toward zero carbon. A couple of recent milestones are adoption by the California Energy Commission (CEC) of the State’s building energy standards, Title 24-2019, effective January 1, 2020, and CA Senate passage of SB 1477 (Stern, Low-Emissions Buildings Market Development); the bill is now Read More »
ZNE guidance for CA architects (& others!)
The American Institute of Architects California Council recently published the Zero Net Energy Primer. I had the privilege of developing the Primer for them under a contract with PG&E. The Primer (if I do say so myself) is a handsome, concise, and accessible guide — a mere 24 pages, including lots of pictures of ZNE homes of all flavors Read More »
A recent email thread involving a group working on a video about ZNE design prompted me to raise one of my favorite subjects. Say I, “Will you talk about the critical importance of roof design?” Queried Steve Mann in reply, “Do you have something more specific in mind?” I’m so glad he asked! It gave me an opportunity Read More »
A Tirade on Energy Models (or, It’s All Relative!)
Lots of people complain about energy models — specifically, how they don’t accurately predict how much energy the occupants of a home (or building) will actually use. This complaint misses the point. The REAL problem with energy models is that there is widespread confusion about what they can/should be expected to do. Predicting actual energy use Read More »

Is there such a thing as TOO MUCH PV on your roof?
My view: NO. The State of California, however, has another view, revealed through planned changes to our venerable energy code, Title 24 Part 6. Around a decade ago the State set “big, bold” goals for all new homes to be ZNE by 2020 (also, for all new commercial buildings to be ZNE by 2030). However, Read More »

Pruning the Gas Tree – A Great Idea!
A decade ago, zero net energy (ZNE) was barely on the radar of the building industry – even barely on the radar of many in the energy efficiency community. And electrification (read: getting rid of gas) was even less a topic of discussion. That has changed in a VERY big way in the last year Read More »

Air Sealing Doesn’t Just Happen
One of the biggest challenges in a high-performance building project is getting the air sealing right … and it doesn’t JUST HAPPEN.
