Katrin Klingenberg, co-founder and executive director of the Passive House Institute of the US [PHIUS] is a visionary leader and inspiring teacher.  Since 2006, she and Mike Kernagis built the first Passive House in North America, established the Institute, and trained hundreds of professionals–myself included–in the Passive House system.

from Steve Mouzon: good advice on sustainability

Architect Steve Mouzon is a proponent of New Urbanism–not only as a means to “livable”–and as he puts it, “lovable” homes and communities–but also as a means to sustainability . His thoughtful blog post on Earth Day 2014 is worth reflecting on:   http://originalgreen.org/blog/earth-day-2014—lean-is.html                

 

Cliven Bundy’s got a beef: On sustainable foods

Dunno where you are on the controversies surrounding Cliven Bundy’s stand against the Federal Government; there are arguments on each side that echo the same issues that Hamilton and Jefferson wrangled with, back in the day. But this controversy obscures an arguably more important issue: how sustainable is the production of meat? Amid the swirling read more

 

Alex Wilson on Affordability

    Alex Wilson, founder of Environmental Building News, and more recently, the Resilient Design Institute, has through the years been one of my primary influences.

Sustainable Living: Some Alternate Takes

Not everyone can afford to build a passive house, or do a green remodel of their home. But they may be living a more sustainable lifestyle–even if it is not their intent. Here are two vivid examples. The first is a brief film by Time Video,  Off the Grid in Slab City–about an ad hoc read more

 

Passive House Moment of Truth: Air Tightness Testing

With most of the rough mechanical, electrical, and plumbing work (MEP) complete, it was time to test the Grant Residence Passive House for air tightness. We scored approximately 0.75 air changes per hour (ACH) at 50 pascals (PA) of pressure. Although this is four times tighter than the current energy code requires–it’s not good enough read more

 

Bill Hutchins: Our Home is an Organism

Keystone

 as vile as the proposed pipeline–and the tar sand crude that it would carry–as vile as all that may be, to vilify the project is much like condemning a syringe maker because it might be used by a heroin addict. the point is that each and every one of us, here in this wealthiest of read more

 

Historic Preservation policy needs to look to the future as well as the past

A list-serve colleague sought advice on selecting an affordable line of wood windows, for a project regulated by local historic preservation mandates.  I replied as follows: I hope Yogi Berra will forgive me if I say that the best and most affordable wood windows today are made of fiberglass. Here’s where I’m coming from. I’ve read more

 

A Passive House Reality Check

Building Designer Certification

Although I am a certified professional building designer, and append that title to my signature, I am often referred to by my clients and friends as an architect.

We were talking about cost effective energy design, and Bill tossed off a comment that read more

 

A Delicate Question

Looking back, some of my most successful—and deeply satisfying–projects have been for gay and lesbian clients. I could not help wondering why this is so. It’s one thing to wonder, and another  to say this aloud. So I decided to first direct the question to the clients themselves, to determine if it would be offensive read more

 

Passive House Certification

Now that the rough carpentry is nearing completion, it was a perfect moment to bring out our Passive House Rater, Andy Corral of Elysian Energy, to see things in the flesh.  I spent a good part of yesterday morning compiling a set of plans and documents for Andy to review, including a revised Passive House Planning read more

Historic Preservation in Montgomery County, MD: Past, Present, and Future: PART ONE

“…it is right to build houses as people wish them…to subordinate tradition…” Gustav Stickley, from More Craftsman Homes, 1912 After more than 33 years of designing and building in the historic districts and vintage neighborhoods of Montgomery County, MD, it seems fitting to reflect on this experience.

a Passive House and Cosmic Consciousness

An uncanny resemblance to a new Passive House Walking down Carteret Street in Beaufort, South Carolina, this house–by its looks over 100 years old–caught my eye.  It bears an uncanny resemblance to my Passive House design, presently under construction in Derwood, Maryland.  It calls into question what forces of cosmic consciousness are in play here. read more

 

THE ESSENCE OF PASSIVE HOUSE

The essence of Passive House–or any kind of excellence in building–is attention to detail.  Here is a prime example:  air tight design, even under a concrete slab.  If there is any hope hitting that hitting that important mark of 0.6 ACH@50PA–almost hermetic construction–it will be achieved by sealing every penetration in the building envelope.  

 

PROGRESS ON A PASSIVE HOUSE

Work on the Passive House continues in Derwood, Maryland. The rough plumbing that goes under the slab–or “groundworks”–is now in place. You can see stubs of white pipes sticking up where the bathroom, powder room, kitchen, and laundry are located. The interior of the foundation has been backfilled with gravel, and is now being capped read more

 

“there is no separation between sustainability and design excellence”

From some comments on what underlies sustainable design by William Leddy, FAIA.

It isn’t just about read more

Sandy Keenan reports on the status of Passive House in the New York Times. Her story is somewhat glib–what’s really interesting are the readers’ comments.

Ann Edminster, Green Building Advisor with a revolutionary mindset

Is Sustainable Affordable, Part 2

Getting back to the core question:  “Is sustainable affordable?” The answer first requires a definition of sustainability—and offers an opportunity to distinguish sustainability from “Green.”  A sustainable method or material—or more importantly—a sustainable project, is one that can be produced in a way that does not significantly compromise other’s ability to produce the same thing read more

 

Is sustainable affordable? Part One
