Breathing Clean Indoor Air
By weight, you breathe more than you eat and drink

Optimum interior air quality has become an increasingly prominent concern in our work. Passive house interior air quality is pristine because highly filtered fresh air is constantly being exchanged with the interior air. The passive house standard requires filtration systems that achieve a MERV (Min...

Integrating building science to build better and smarter

The term 'passive' in the context of passive house refers to the reduction or elimination of 'active' mechanical systems. There are many compelling reasons why this is a more intelligent and responsible way to build. Here is a quick list of benefits - in no particular order:- Increased comfort.- I...

The 2030 Challenge: All new buildings, developments, and major renovations carbon-neutral by 2030

The built environment is responsible for three fourths of annual global greenhouse gas emissions: buildings alone account for 39 percent.  Eliminating these emissions is the key to addressing climate change and meeting Paris Climate Agreement targets. The American Institute of...

Why We Build Buildings Twice
See it all - before it's built

Before our projects are actually constructed on a site, they are built first in our studios, in a comprehensive computer model. Working closely with specialized experts in each of the disciplines involved, we model every system in the project... not just the architecture, but the lighting, plumbin...

Architecture and Water Vapor
Why understanding building science is crucial

Water is one of the most powerful forces of nature, and one of the primary variables determining the durability and performance of buildings. Depending on the climate, regional building design responds directly to rain, snow, and ice, but another powerful form in which water interacts with str...

"... If it leaks, it's art."

That natural forces will act on, and ultimately destroy, any contribution we make to our built environment persists as one of the few things we can be sure of about the fate of any building. For architects, this presents a challenge somewhat analogous to that of medical professionals who, desti...

Air sealing is the 'secret sauce'

Passive House architecture: Healthy, comfortable places to live and work that use a fraction of the energy of mainstream construction. Many people presume this must be all about insulating really well, and while that is important, the amazing performance of a Passive House project actually begins wi...

'Passive house' reliably performs - it's pure physics

One of the most common misunderstandings we see about our high performance architecture is that we are preoccupied with passive solar design - which is actually something we don't have any particular interest in.  It's easy to see why this confusion happens: Passive House (or Passivh...

Knowing exactly what sunlight will do

One of the many aspects of site specific architectural design now standard practice in our pre-design research process is to acquire a forensic understanding of the shading conditions that will alter how our architecture will be exposed to the sun over the course of each year.Designing high perfor...

HERS Index: The Home Energy Rating System
It's like having a car dealer window sticker for your home

 The Home Energy Rating System (HERS) Index is the industry standard by which a home's energy efficiency is measured.   HERS scores are designed for new homes (or homes after a complete renovation). When builders need to meet efficiency standards, they use the HERS Index, which has...

Just in case you were wondering

“Environmental control systems tend to be treated rather like the Cinderella of architecture; given only the plainest clothes to wear, they are relegated to a back room to do the drudgery that maintains the elegant lifestyle of the other sisters: light, form, structure, and so forth." ~ Lisa Hesch...

Toxins have no place in our everyday lives

Building with toxic materials is such a bad practice, in part because we are embedding them into environments where people then tend to have long term exposure to them. It's good to be aware that carcinogenic and toxic material is not only found in scores of products in the building industry, but ...

Forensically accurate sun studies

One of the first things we do with a new project is build a detailed and accurate three dimensional computer model of the land and its physical features from a survey. The survey work is usually completed using both a laser theodolite and satellite GPS data. The topographic model created from this d...

Offshore sources are highly suspect

Most ceramic wall or floor tile is now manufactured out of the United States, and the use of highly toxic heavy metals in the glazes is common. Most of the tiles you will see, especially in retail outlets, were manufactured in China, or in Cambodia or Vietnam by Chinese companies. The environmenta...

The win-win option you need to know you have

Europeans have lived with high energy costs for a long time, and have a strong pragmatic awareness of the costs associated with heating and cooling buildings. So it may come as no surprise that the leading standard in energy savings comes to us from Germany: The Passive House standard. It's not a...

The First Step to Net Zero Energy
Begin by reducing the need

A 'net-zero energy' building generates more energy than it needs. The most important item in Net-Zero design is reducing the demand for energy. This is the main principle behind the Passive House concept, so it should be a natural progression for architects designing to the passive house standard to...

Biomimicry: What plants can teach us about storing energy... Good bye, fossil fuel dependency! The main challenge with sun and wind energy is storage. Because the sun isn't always shining, and the wind isn't always blowing, we need to be able to bank away renewable energy when it's available for ...

Why build with stuff naturally destined to burn, decay, or rot?

All the rivers run into the sea, and yet the sea is not full.  Ecclesiastes 1:7 Waste does not exist in nature. In the natural world, everything is cyclical; everything happens in closed loops and dynamic systems of loops. One familiar example would be the hydrological cycle, in which e...

There is no energy crisis, only a crisis of ignorance

It is no secret that our dependence on oil reaches into every aspect of modern life. This must change - actually, will change, whether we like it or not. Not only are we wreaking environmental havoc burning fossil fuels, it is certain the costs will continue to dramatically rise, impacting every cor...

Conventional assumptions turned upside down

We assign a very high priority to comfort in buildings - specifically, thermal comfort. One of the basic distinctions between being inside' and 'outside' is that when we are inside, we expect to be comfortable.

Passive energy storage sinks can lower heating and cooling demand

Putting Nature's Magic to Work For Us: Phase Change Materials We see it all around us, all the time; temperature changes make stuff freeze, melt, or vaporize.

Any architectural firm worthy of the title must excel both artistically and technologically

In Western culture, science and art are often thought of as existing in separate worlds. Our higher educational institutions support this notion, for example - coursework is generally offered in the arts, or in the sciences. Yet we need look no further than the rise of Apple to recognize this is a...
