The Enertia House
00/00/0000, 00:00 | Green Home Building and Sustainable ArchitectureThe Mother Earth News editor said that these homes had been featured in their magazine before. They essentially provide two wooden shells for the home, one inside the other. She said that there was no mention in the article about the cost per square foot. She was wondering what I thought about the concept from the standpoint of sustainable architecture.
Here is my response:
Double envelope house designs have been around for several decades and they definitely offer some benefits, as well as raise some questions. Any house that takes advantage of the geothermal properties of the ground will be doing its inhabitants and the earth a good turn. This can take the form of earth-sheltering in general, or some clever system of circulating air like the Enertia concept; coupled with sensible passive solar design, it is possible to approach a "zero energy" home.
The concerns about their system that I have are: The use of wood as the primary building material is not generally sustainable in this day of lost forests. With the double envelope design, you are practically building two houses to end up with one. Relying on wood as a thermal mass material compromises the potential thermal performance because wood does not serve this function nearly as well as traditional masonry thermal mass materials. So, I guess what I am saying is that a more sustainable and less costly design can be accomplished in more traditional ways.
Clark Snell of www.thinkgreenbuilding.com wrote, "I spent five minutes looking over the web site, so these comments are only based at looking at marketing materials, i.e. they may be inaccurate. Ditto what has been said so far. A couple more “red flags:”
- Solid wood envelope. They seem to be using the old “mass enhanced R-value” argument for why solid wood walls perform well thermally. I think it’s well established that this is true only in very specific climatic situations. Touting solid southern yellow pine walls in comparison to solid white pine walls is like saying a Chevy Suburban gets better gas mileage than a Hummer…that’s not really a useful statistic.
- Energy without oil. The presentation intimates that this is a completely passive design. For example, no heating system is mentioned. That simply isn’t credible for most climates using the technology they are describing.
- Passive means local. You simply can’t create a design that relies heavily on passive techniques and generalize it across climates. In my area where we have high humidity, I’d wonder about this convective loop through the attic and basement, for example.
I could go on. I’m a passive design freak, so I’m all for the basic concepts they are dealing with. However, I don’t see anything really new here, but see marketing claims touting what they are doing as a major breakthrough and “the answer”. That always makes me nervous."
David Eisenberg, of www.dcat.net wrote, "After a skimming around their website, I see that they sell kits and their base prices don't include a lot of things - some of which are enumerated:
That's a pricey list of not includeds and notice they say nothing here and I saw nothing in my quick scan of the site about some really big and typical costs like excavation and foundations, below grade walls, or basement floor. They say this is a structural package but they don't mention all the things that are going to be extra that most people would expect in a house - plumbing, wiring, fixtures (electrical and plumbing), stove, etc. and especially that the solar PV and thermal water heating systems are not part of the package. It would be nice if they said right up front and clearly what they do and don't sell. And they should make it very clear that all the prices include only the factory labor, not the cost of actually assembling and finishing these structures.
But the biggest issue I have is that these are essentially double wall structures using an enormous amount of thick, milled lumber, which appears to use many times more wood than goes into a stick frame house. It would be interesting to see if they use more wood than a comparable log home. They'll likely be more energy efficient than a log home, but they'll use as much or more wood. Which raises all sorts of issues about the sustainability of this venture - beyond just the trees cut down - much bigger transportation, milling, probably kiln drying impacts as well. The concept is fine and likely works reasonably well in most climates. I'd need to see much more actual performance data and of course real cost data to be able to make any kind of realistic judgment of the viability of this concept as anything more than a niche market system. But between the costs which are going to be very high and the amount of materials going into one of these, calling it sustainable seems like a real stretch."
And finally, Jeff Judkoff of the National Renewable Energy Laboratory, wrote: "The concept of "Double Envelope" homes has been around since at least the 1970's. A number of them were built in the late 70's early 80's. Some variations of the concept were published in the Solar Home Book, by Bruce Anderson and Michael Riordan in 1976, Cheshire Books. Other publications in that time frame also showed the concept. The only truly new concept here is the notion that the resins in the wood behave as phase change storage materials. I have no idea if that is true, but I doubt it because the most common phase change is from a solid to a liquid, in which case the resins in their liquid phase would leak out creating a mess. That's not to rule out the possibility that some tree resins could go from a solid to semi-solid phase, or that they are encapsulated in the wood, I just don't know if they can, and would only be able to determine it through controlled scientific testing in a calorimetry chamber. Phase change storage can really be a big boost to the performance of many flavors of passively heated and cooled homes.
There are many ways to acheive highly efficient homes that more or less "heat and cool" themselves. Different approaches have different costs and will work better in some climates than in others. In Colorado, my lab, NREL, worked with Habitat for Humanity to create a net energy producing home. We used super insulation, passive solar tempering, ventilation heat recovery, engineered shading, solar hot water with a backup instantaneous water heater, compact flourescent lighting, and PV. We also have more than a years worth of detailed data to prove the performance of the home (it really was a net energy producer for the last year).
I saw no data to indicate how well the Enertia home actually performed from an energy perspective. Cost, energy performance, and comfort are the key criteria by which to evaluate such homes, and data is always better than arm waving, or catchy theories. Nothing beats the scientific method for objectively determining the value of an idea."
My Thoughts on Greg La Vardera's "Our Re-Modern Movement - The Tipping Point?"
00/00/0000, 00:00 | FUTURE HOUSE NOWI had always been interested in homes. I always dreamed of something better and more exciting than the standard fare of suburban cul-de-sacs, though I wasn't totally hooked on modern yet. But when I saw this cover, with a real family in a cool-ass house, it was like a lightning bolt. I can't tell you how badly I'd like to live in a Flatpak. It's one of the top three contenders for me. It just fits me and my family so perfectly. When the time finally comes to really build a new home I will be giving them a call to talk.
It's funny though, how "weird" most people think modernist homes are. My mother said "you want to live in a white box?" with a look on her face that was pure disbelief. Talking houses with some neighbors I could detect their nervous smiles when I mentioned concrete and steel, as in "uh, okay, sure, as long as it's not next door to my house." And look at the real estate markets. That's all you need to know. You don't see a lot of developers building modernist spec homes. Just pick up a real estate magazine and thumb through it for a minute. How many cool modernist homes will you find in the listings. Maybe one or two in a hundred page book. And they're mostly really big, expensive houses, probably built in the eighties after watching too many episodes of Miami Vice. Good, simple, modern homes for real families are hard to come by. Your best bet is a fifties ranch. Even those are a minority in the market compared to the grand total of everything else.
But I think Greg is right. This is the right time. Dwell has been so successful that some other similar publications have started to appear. Blogs like mine are popping up like daisies. Sarah Susanka's "Not So Big House" movement has a lot of followers (because it makes a lot of sense). Or consider John Brown's Slow Home Movement. And green is suddenly king. People finally realize that their choices have a real impact. Now is definitely the time of Less is More, and modernism fits that bill perfectly.
Probably the biggest helper in all of this, in my opinion, is going to be the bursting of the real estate bubble. I say that for one simple reason: it will make people change their view as to what their home really is - a home to live in and not an investment to make a fortune off of. I really believe that people won't/can't build what they really want because they are too hung up on resale value and growing massive equity. I don't know if this attitude caused the housing bubble or vice versa, but either way they combine to create an effect where the resultant high cost of housing distorts our views, closes our minds to new ideas, prices lots of people out of the market for a good home, and places too much power in the hands of developers, not in the hands of consumers where it should be. And so, here we are. With the bubble busting and home prices correcting I think we may also see home buyers making very different decisions about what they want to live in. I know this is the case for my wife and I, and I hope, at least, that this is the case for others.
It's definitely time for America to focus its attention on things like better homes, greener communities, reliable energy, even better communications technology, education and health care. These are the things that make up the infrastructure of this country. We won't have to worry about foreign threats for long if we allow ourselves to fall apart from the inside.
This whole country is at a tipping point, or near one. Modern homes are just a tiny, tiny part of that. We can choose a better way to live without giving up all the really great things we already enjoy.
Better living through design. Work smarter, not harder. Find the holistic solutions.
We can do it.
Bernardes + Jacobsen - CF Residence
00/00/0000, 00:00 | Modern Residential Design
Steeling the show - Blessed with a great plot and open brief, a lightweight, transparent, horizontal building, was what the architects Thiago Bernardes and Paulo Jacobsen designed.
Overview & Plot
Located on a plot in the picturesque condominium Portogalo in Angra dos Reis, Rio de Janeiro, Paulo Jacobsen and Thiago Bernardes wanted to accommodate a large family retreat taking full advantage of the plot and its location. The challenge was how to minimise the buildings impact from roadside - difficult with such a large house.
Departing from traditional Brazilian wood or brick structures the house employs steel to span the vast openings that connect all rooms to the views below.
The svelte steel corner pillars provide minimal interruption to the open plan dining and living area of the ground floor. In summertime (almost constant in Angra dos Reis) the glass panels dividing this area up slide away to provide an enormous expanse of shade.
Half way up the façade, and providing elevated viewing to the bedrooms are two outdoor balconies of Peroba wood, these break up the stark white of the lower level and the surrounding steel structure. The wood is also used throughout the second level interior, and as a lining the the vast roof span.
Continuing to the roof level, tropical storms and heavy rain, common in the early part of the year in Rio de Janeiro are caught by large glass overhangs, which still let light through to the bedrooms. The glass also blurs the connection between the roof’s reflecting pool, paved with green ceramic tiles, imitating the colour of the inlet and sea beyond. The same applies to the pool on the terrace, which seems to fall into the sea. This camouflage, and the fact that the house is set into the hillside at the rear, reduces its size, as to the thin steel structures, elongating its horizontal structure. It’s only from below, backstroking in the pool that the house’s true size is revealed.
Layout
With the entire ground floor dedicated to the pool, dining and entertaining, the upper level provides the entrance and 4 bedrooms with en-suite bathrooms. Originally two giant bedrooms, the sets of two our housed either side of the atrium over the pool. As you enter the residence through its large dark wood doors, the bedrooms act as blinkers, focusing the view out to the water beyond.
A small seating area between allows you to contemplate, and perhaps acts as a formal arrival area. From here, “grand” staircases head both inside (left) to the living room, and outside (right) to the pool area (Bernardes + Jacobsen are renowned for impressive staircases).
The Result
Now complete in a 4 bedroom layout, this family retreat seems to have all one needs for a relaxing weekend. The thin steel structure and stretched horizontal roofline give it the appearance of a lightweight marque or stretched canvas roof. A seaside camp that mirrors the water beyond. Yet, from within, there is no doubt that this house is: permanent; modern and luxurious; and will provide a great weekend spot for years to come.

Shubin + Donaldson Architects - Urban Spa
00/00/0000, 00:00 | Modern Residential Design
Urban Spa - Shubin + Donaldson Architects have remodelled this house to soak up its Malibu shore front location. Sliding doors and windows allow the residence to be open plan or sectioned off at will. The site elements of the highway and beach challenged, and dispatched with charming results.
Program
The initial task was to renovate the original 1976 dwelling into a contemporary urban retreat, whilst adding some structural reinforcement. Bought in 2001 for it's location, the owners, together with the architects, went on to extensively remodel the house into an urban oasis. Concious efforts to negate the road behind and emphasise the beach in front are evident throughout.
Design
The overall concept for this 2,900-square-foot beach-side modern house was to transform it into an urban spa-like retreat. The house is perched along Malibu’s Pacific Coast Highway, and features access to the beach at the back. Sheltering the house and providing a hard façade is the garage to the rear. As an area of transition between the street and beach, an interior entry courtyard behind the garage, laid with rectangular cement pavers and bordered by smooth river rock and tufted grasses, introduces the primary design element of the home — a seamless union between interior and exterior spaces. Through crisp linear architecture, a split level plan, and visual access throughout the house brings in the beach.
From the entry courtyard, a line of sight straight through the living room takes in the sea views. Dragging your attention away, to the left is a bay window type dining room, accented by a white grid of window panes and shadowed from the noon sun. This window grid is echoed by the geometric pattern of the cabinets and shelves that lead into the minimal kitchen. True to the open plan, the kitchen seamlessly overlooks the main living space, allowing distractions whilst cooking. 
The interior design palette of natural woods and limestone, white walls and fabrics, frosted and clear plate-glass creates a crisp and airy environment to appreciate the Pacific Ocean setting. A true Urban Spa,the elements were hand picked to portray the theme of air, light, and water.
Ground-floor living room and adjacent sitting room offer shadowed relief from the sunlit terraces beyond, with cooling white and dark wood tones in the furniture and materials. Double-paned windows, which open onto the first-level terrace, offer several ways for freedom, permitting unrestricted views onto the ocean while buffering sound (from the highway). 
The upstairs rooms continue the overall theme of air, light, and water with repeating materials and colours. The well-dressed master suite faces onto a second large terrace with pocket-glass doors that fold away, converting the stepped upper terrace into a sleeping porch reminiscent of designs by Schindler and Neutra (and last weeks post - David Hertz! [Image]).
For reclining on the teak chaises, billowing fabrics can be drawn above and alongside the terrace to shield the sun and wind.
With the clients goal being a boutique like retreat to entertain guests rather than as a reclusive beach getaway, opulent bright-white materials: Limestone and high gloss surfaces were used to give that crisp light filled feel. In fact, the owners found it too 'bling'. The house was cool crisp and far too full of light, with the white being overwhelming sometimes. Aware of this, Shubin + Donaldson had already incorporated exterior shutters and shades, which compensate in the southern facing rooms. Then in terms of layout, a simple North facing Media room was added with minimal windows at the rear, providing a further space to retreat in summer, and a little getaway for all. 
Openness and transformation are themes throughout and are most expressive in the master bath. Cool, ocean-blue frosted glass lines the walls and windows (that face another house on these sought-after lots). Behind the glass swing doors are the toilet and shower. Three layers of floor-to-ceiling glass form a translucent door that closes the space off from the bedroom, or opens it up to the master suite, porch, and Pacific Ocean beyond. Dark wenge wood - used throughout the house as an accent - encases the tub, vanity, and spacious closets. The rich brown colour gently contrasts with the limestone counters and floors. Double mirrors are placed on poles in front of the frosted glass, rather than set into a wall. To name-drop, the tub is designed by Philippe Starck.

Studio di Architettura Marco Castelletti - Casa del Masso
00/00/0000, 00:00 | Modern Residential DesignStudio di Architettura Marco Castelletti
Razionalismo Comasco - A near vertical site in Como, with stunning views, let Marco Castelletti nod to local Italian architecture of the thirties, whilst bringing his clients a modernist house, proportioned and segmented with precision.
Overview
"At the end of 2002 the clients approached us to design the house.
They wanted to build this new house next to their one, in the garden facing the lake, and they were after something typically razionalismo comasco, architecture of the thirties driven by architect Giuseppe Terragni. So they chose the project that best met their expectations, ours. The project's main idea gave the name to the building: casa del masso." Marco Castelletti.
The house, set on a steep slope above the street, can be clearly seen across the lake.
The building stands by the side of the client's old house designed by engineer Luciano Trolli in 1955, and it takes advantage of a little tract of flat land, as does the original residence.
The house is linked to the street by a long flight of steps which wind along the slope and down to the house, which is organised over two floors.
Layout
The composition is based on the intersection of two volumes:
The first - facing the lake, is an horizontal structure supported by pilotis houseing all the living and bedrooms.
The second - is vertical holding the staicase and the services rooms.
On the first floor the living room crosses the house and is directly connected with the slope behind. Here the presence of a erratic boulder, in italian language "masso" (here is where the name of the house comes), protrudes into the dwelling as the characterising element of the space, so that it seems that the house is anchored to the slope at this point.
The boulder can be seen through the glass floor of the living room.
From the parking area you reach the main entrance via a flight of steps or an elevator running on the side of the garden.
After reaching the main entrance a footpath covered by a overhanging volume introduces a little hall where you can see the landscape and the monuments of the city.
From here, a large staircase takes you to an atrium with the large glass window which frames the erratic boulder. The internal layout of the main dwelling faces the kitchen, the living room and some other rooms towards the lake, while bathrooms, services and the laundry are put towards the slope.
The materials used to build the house enhance the volumetric composition and the difference between the horizontal volume, suspended and completely covered by white marble dust plaster, and the vertical covered with a natural stone called Iragna, laid down in horizontal layers with different length and thickness.
The same stone was used for the external pavements, the main entrance staircase and the terrace floor on the highest level.
The large windows are divided in sliding parts with electrical rolling shutters made of aluminium.
Solar exposure is optimised wit hteh building orientated with its largest windows and rooms to the south, and services and bathrooms facing north.
ResultsThe clients were really satisfied of the project and followed all the phases of the building that, because of the particular nature of the steep land, involved many challenges.
The crane to build the house was placed on the slope with an helicopter used to transport heavy weights. None the less, the house was completed in seventeen months, from May 2003 to December 2004, as stipulated.

MODERN HOME - 2008 living the dream
00/00/0000, 00:00 | GAILE GUEVARA
My 12" powerbook, black moleskin with notes for the day, a hot cup of lady gray tea in my favorite double walled glass and 3 books of inspiration on architecture details, an architectural firm I admire and an amazing topography book
BOOK #1 - TOPOGRAPHY23, The Annual of the Type Directors Club
This is when I know I am a total design geek when I judge a book by it's cover. I love the white glossy slightly transparent cover with minimal type. In reading more about the art of topography and finding inspiration for various projects this year, I highly recommend this book for those who have an appreciation for image, branding, packaging, and a fetish for fonts and layouts. My favorite quote "It has been said that typography is the architecture of the printed word because it makes thoughts visible and understandable. As there are manifold ways of laying out a building, there are - nowadays more than ever - varied ways of formulating the typo/graphics of a book, a brochure, a poster, or any media in which print is used" - Klaus Schmidt.
BOOK #2 - MAK ARCHITECTS
While I love white, I also love black! I love the matte black cover with black edged pages revealing full sized images bleeding off the page to examples of perspective sketches, concepts, and bubble diagrams.
We often refer to the design icons of our past when searching for inspiration. How great is it to see our present day design professionals have their work published and setting the tone for high caliber architecture and interiors. Multi-disciplinary firm Mak Architects shares with readers their process as a dynamic team who's synergy of a young talents give each client a unique solution vs. the traditional mind set of working with an architect for their "inhouse" style.
-"Working in architecture is characterised by participating in may processes: from planning to construction, from dream to reality from work to play. Throughout the process many things can influence and shape the intended goal. MAK Architects understand 'process' as fluid and open, their body of work cannot be defined as a monograph or a mere representation of process. Compiled in this book, the MAK approach comes across as both conventional and playful intone and is marked by a strong desire to engage with how environments can become meaningful for the user. MAK's body of work is reflective of how architecture is produced within the service economy of global city. Their unique position within the design world is evinced by the complex contemporary urban projects presented here. This book is a recording of the evolution of an architectural practice through the progression of many authors and users, and is essential to anyone interested in current architectural developments." - Phaidon Press
BOOK #3 - DETAILS IN CONTEMPORARY RESIDENTIAL ARCHITECTURE by Virginia Mcleod, Laurence King Publications
An excellent book showcasing modern residential architecture with beautiful photography, floor plans, and the construction details that reflect the precision of quality in seamless transitions between materials.
With no book shelf yet, aligned against an exposed brick wall, I read though a collection of books we have from design, architecture, martial arts, photography, floral design, interior styling to programming ... the list goes on, as much as we use the internet daily, there is nothing like flipping though the pages of a good book. "turning a new page" ...
It's 2008 and there is so much to be excited for. While the last 8 years of working in the design industry have been an interesting collection of career paths and amazing opportunities of working with many great talents, I am grateful to look forward to sharing more of what I've learned is a passion of mine - sharing resources. Modern design and meeting the talents behind these great projects has become a great source of inspiration. It's hard to believe at times how designers have this bad wrap for being so hush hush when it comes to their resources, that for some reason this information is something owned. Reality is that the world of technology and speed at which information sharing is advancing far more quickly than what some might think. In a day where the internet has become the #1 source of information for not just saving time, increasing efficiency as well a source for learning. We are just at the beginning of what lies ahead. I learn that the more information I share with other liked minds, the more I learn through this process of corresponding and discussing modern concepts.
Closing thoughts:
This is the little guy who helped me through a few of the hardest years in my life, I am grateful to have shared these moments with him. 2008 marks a new beginning and I say good bye to Tyson knowing, that our time together was one I will always remember for the good things that have brought me here and have made me grow into the person I always want to be. Unconditional love and appreciation for all that is in my life today - I thank this little guy for always reminding me that learning to love yourself is the most important lesson we can all learn. That finding your passion for what makes you wake each morning thankful and excited ... I hope 2008 is a year we all make the changes to living our dreams.
