road rage at work
10/31/2008, 01:04 | InfluxinsightsWhat could companies do that are located in cities with tough commutes?
1. Encourage use of public transportation- if it works and is reliable
2. Build decompression chambers in the office
3. Create employee transportation systems- like Google's bus
4. Stress management advice- teach employees how to be less angry about their commutes
5. Yoga classes for commuters
It's not entirely surprising that road rage makes its way into the workplace, but I am sure very few companies pause for a moment to think about it and what it could be doing to their employees.

Stone Houses
00/00/0000, 00:00 | Green Home Building and Sustainable Architecture
This is a picture of one stone house that happened to be for sale, with about 3 acres of land for about $90,000 US. Some of the wood around the windows was rottiong out, but the rest of the structure appeared sound. One of the beauties of stonework is that it can last for centuries and be as sound as the day it was originally built!


Arkhefield - Couran Point House
00/00/0000, 00:00 | Modern Residential Design
Island retreat - The team at Arkhefield bring us one of their latest residential wonders in form of a simple, low maintenance, sustainable living volume which can be enjoyed all year round. The motives behind the design - maximising space and privacy - are attacked head on, as are the isolation and harsh climatic conditions on the island with basic low maintenance materials. The resulting simplistic structure, appears as a coastal tree, with its roof-line shaped by the strong winds and elements. Elements from which it can hunker down further, shelter, isolate and reorientate the use of external spaces.

Overview
The house offers a stark contrast to the predominant low shacks by the way that it expresses and celebrates volume, simplicity of form and its ability to manage/manipulate the external environment. The house appears to be inspirational amongst the community with many new houses currently under construction on the island being designed and sited in a similar manner.

The house is a simple extruded profile with its form being solely dictated by town planning constraints. Height, setback and roof pitch essentially created the volumetric section which was extruded to the road and waterfront boundary, then set back to maximize the enclosed space. The house breaks out onto the terraced waterfront on the east, for summer fun and to an enclosed "winter courtyard" on the west. The relatively closed north and south façades retain privacy from the adjacent blocks, and shelter from strong summer sun. 
Design
The isolation of the site put a premium on the construction cost as all materials and skilled labour had to be barged out to the island. These constraints created unique challenges and encouraged a rethink to heavy/bulky build elements that couldn't be barged out to the site. Environmentally Sustainable Design principles of orientation and sitting along with use of solar, gas, rainwater harvesting, bamboo cladding/screening and a thermally efficient monolithic floor slab were all core ideas behind the build.
Layout
The house is split in half down the centre of its length with a large double volume "communal" living space on the north and a 2 level "private" core, comprising of bedrooms and service zones, on the south. The interplay between the two halves of the house creates a sense of inclusion and encourages interaction between family and guests whilst still enabling privacy and seclusion.
Our clients desire to recreate a "Bahaman" styled beach cottage with shingled, pitched, roof and quaint shuttered windows made for a challenging brief. They wanted the house to take them back to the memorable vacations they had spent in exotic locations. Through exploration and development it became evident that decoration and themed architecture may enable brief relapses into the bygone but that intelligent design and the creation of flexible spaces stimulated communal interaction, which was what really recreated that relaxed holiday atmosphere they were seeking. They are extremely happy and are enjoying there "Contemporary Bahaman" cottage which they have aptly named "the shed" out on Stradbrooke Island.
Results
The team at Arkhefield have managed to strip back this brief to the real essence of what the client was after. Conviviality and family togetherness were the clients true request and the flexibility of the hoses and its communal spaces are what makes the house such a wonderful island retreat.

goat cheese pear tarts
00/00/0000, 00:00 | Design*Sponge
in the tradition of friday’s on d*s i decided to add a recipe to the mix for today’s DIY project. i love goat cheese. i could eat so much of it’s sick. last fall i spent some time researching different tart recipes after i got these cute little “mini-tins” as a gift. i finally settled on trying goat cheese with pear and loved them. these are so easy + they have the advantage of looking like they’re not. they satisfy the sweet & savory thing that i tend to crave. bring them with you to holiday parties and blow those chip & dippers out of the water.

what you will need: (makes 20)
mini baking tins (a mini muffin pan or the like will work)
2 pears
10 oz. goat cheese @ room temperature
1/2 tbsp sugar
dash of cinnamon
1 package puff pastry sheets (in the frozen foods aisle @ the grocery store)
1) preheat oven to 400.
2) roll out 1 puff pastry to a 20 x 20 inch square with a rolling pin,
and cut into 2 x 2 inch squares. grease your tins so the pastry does
not stick. press squares into tins and trim off the excess.
3) chop the pears finely with the skins on. (this adds a little color
to the tarts). stir pears, sugar & cinnamon up. you will probably have
a bit of the pear mixture leftover.
4) spoon and press down 1/2 tbsp of goat cheese onto the bottom of the
pastry and add 1 tbsp of pear mixture on top.
5) bake at 400 for 25 minutes. the edges should be golden brown.
6) take out of oven and let cool for 10 minutes. you will be able to
pop them out if you properly greased your tins. enjoy. i like to serve
them with a nice glass of white wine. yum.
Earthbag Building in Haiti

This project not only houses over 700 children, but has an agricultural project, three schools, carpentry and masonry facilities, and an arts and crafts program. They have many ideas to help the Haitian economy and people living there. Because they are a non-profit, and are continuously struggling with funding, I encourage you to visit their website (www.freethekids.org) and consider making a donation to their cause.

F3 Arquitectos | House in Rupanco
00/00/0000, 00:00 | Modern Residential Design
Wooden Wonder - F3 Arquitectos - renowned for their timber architecture in Chile, have created this wonderful prefab retreat in 75 days! I question what more could be required of a modernistic cabin?
Many thanks to Plataforma Arquitectura for bringing us this fantastic residence in Southern Chile.
Translation / reword of original article by Carlos J Vial
Located in a remote area of Lake Rupanco, the commission responds to the request of a "summer house" or retreat, of sporadic use. Due to its complex, ever changing climate and geographical location, the plot made on site slow construction impossible.
The project consists of a single volume, with the layout distributed linearly, parallel to the lake views and shore. The site drops down a field to the shore below and northern sun.
A solid timber rear façade with a singular overlapped entrance, to the house, provides the necessary private secure barrier to the public road, becoming the main structural axis of the project. This wall in turn partially meets the requirements of security due to the prolonged periods when the house is uninhabited.
In contrast, once inside the interior, each room has a glazed wall facing the lake, creating a porous, and therefore vulnerable, façade. F3's solution being sliding wooden panels, clad in the same treated wood of the rear façade, that allow the owner to create a singular, completely airtight volume when leaving for the city.
As for the remote location and inclement weather that would hinder an on-site build - this was resolved by prefabricating many of the wall, floor and roof panels.
The Result
A beautiful, simple, elegant lakeside retreat. And to top it off, construction was completed in 75 days!!

Location: Lago Rupanco, X Region, Chile.

00/00/0000, 00:00 | FUTURE HOUSE NOWFirst of all, why do I often post about green homes, even when my site is not purely focused on green issues? Well, for starters, green makes a lot of practical sense. It's laughable how much emphasis we put on greening our cars when we spend way more energy in our houses. It should be obvious every week when we take out the trash that our homes are the epicenter of our consumption habits. And I care about my family's health. I want them to live in a safe household environment, not one that is riddled with toxins and allergens.
Second, green isn't that hard to do anymore. You don't have to live in an Earthship made of tires pounded full of dirt, and old aluminum cans to be green (though that's pretty cool if you ask me). You also don't have to be an eco-warrior living off the grid in Northern California, growing all your own food and living off $10,000 worth of yearly organic produce sales. I guess what I mean is that being "green" isn't really an extreme lifestyle choice, it's part of everyday life for everyday people all over the USA. We have to stop treating green as extreme. Frankly, I think that alienates more people than it attracts. That's why I try not to overplay my green views, just as I don't downplay them either. To me, the important thing is that we're all constantly raising our awareness and incorporating green practices in our lives one little step at a time.
There are so many good ways to green any home, any style, old or new, anywhere. How about more efficient appliances, compact fluorescent light bulbs, better insulation, and low-VOC paints? These are pretty easy things that can make a big difference. How about not using those toxic cleaners in your kitchen and bathroom? Use good ol' white vinegar - it works great and is non-toxic. Inexpensive too. And great technology is here, with real strides in renewable energy being made every day. The reasons for not taking advantage of better technology for greener homes are becoming fewer and fewer. We're pretty much at the point where going green isn't about making tough choices, it's about making smart choices. The difference now isn't as much about toughness as it is about awareness.
I like to show interesting modern homes, and some of them are not particularly green. But lots of them are, in lots of different ways. Some are green just because they are compact. Some are green because they have a broad sheltering roof and good insulation. Some are green becaues they make good use of recycled materials, or new materials like steel framing that will last a long, long time without a lot of costly maintenance, and that can be recycled someday if need be. Maybe they aren't all perfect, but we can learn something from them. My site is about ideas. Some of the good ideas I like to show are about environmentally friendly homes, and some of the ideas are about other things. They're not mutually exclusive. And we have to stop thinking in those terms. Green fits with modern because they are both about good design. Good design has logic, economy and beauty all rolled into one. I see green as a part of that, not a whole unto itself.
Don't get me wrong, I don't take green for granted. I accept green as a matter of fact. That's how it should be - a natural part of life, not a radical philosophy. I view the recent mainstreaming of green as a sign that we've finally turned the corner. It won't be long now before we build the momentum to make lasting positive change. The challenges are real, but humanity, in spite of itself, is a problem solving species. We can do it.
sumika projects by sou fujimoto, toyo ito, terunobu fujimori and taira nishizawa
00/00/0000, 00:00 | designboom weblog, design related news, reviews and previews
tokyo gas co., ltd., is japan's largest supplier of natural gas for both residential and business consumption.
for their 'sumika project', they teamed up with japanese architects toyo ito, sou fujimoto, terunobu fujimori
and taira nishizawa. each of the architects are responsible for designing a built structure on the project site.
the concept behind sumika is to provide new residential units, buildings and a main pavilion that will use gas
as their main source of energy.
the main pavilion is a communal space that is meant to bring people together, to gather and interact with
one another. with the increasing amount of people living in apartments in urban areas, homes have become
uniform and monotonous. the aim of the sukima project is to provide more primitive, free and prosperous housing
which connects to nature and awakens the five senses.

We all know the drill when it comes to meetings: Arrive prepared and in time, stick to the agenda, don't interrupt others and let them speak until they're finished … But we all do also know that we so often suck with these basic rules.
Therefore I'd thought that it might be a good idea to have the basic rules written down. This is no matter of being a business or design manager. On the contrary maybe some more structure in discussions would very often help meetings on design, process, and aesthetics to be more effective … What are your experiences?

MacGabhann Architects - Tuath na Mara Residence
00/00/0000, 00:00 | Modern Residential Design
Armoured Longboat - Standing vigilant over a northern Fjord in Ireland, the Tuath na Mara Residence, by MacGabhann Architects appears solid as a rock. Zinc clad for resilience, the low slung house blends seamlessly into the heather-covered rocky landscape, its own seams, echoing the strata of surrounding rocks. Contrasting a well hunkered core, the roof line warps and twists upwards like wonderful grey weathered seaweed, revealing the surrounding views to the living areas.

Overview
The project's focus around the specifics of the site and putting the personal and particular experiences above the powerful and the public, seeks to create a mood which is meditative instead of tensing or relaxing.
The site is hidden from the public road and is accessed from high ground on the landward side where the first experience is of an elevated view of the site and the sea beyond. Therefore the importance of the roof, or fifth façade, dictated a metal zinc cladding which is suitable for both walls and roof. Said façade, mimicking the seaweed found on the shores beyond. The anthracite colour of the zinc makes the building camouflage itself into the heather landscape.
The roof of both living areas is flipped and directed in opposite directions and towards particular points in the landscape and sunlight. Both living areas are fully glazed, thus embracing nature and developing a conversation with it. By way of contrast the sloped slit windows of the bedrooms act as a counter point to the absolute horizontal of the ocean horizon.
In order to emphasise the fact that the owners were embarking on a holiday each time they entered the house, the step and entry ramp at the front door is disconnected from the building thus making the visitor step over a gap not unlike stepping from the static platform onto a passing train. Thus a physical step from the day to day life into this adventurous house.
Layout
The plan form was inspired by the traditional narrow cottage and is orientated towards warm southern sun. It contains three sleeping cells and auxiliary spaces in the middle with two living areas, one at each end, connected by a library. Glazing is relative to the function of the rooms, with the centre bedrooms and auxiliary spaces horizontally glazed with small landscape framing windows, while the end living areas are wide open to the surrounding views.
The roof rain water is drained by way of gargoyles making one aware of the elements even in the lightest of showers, thus reinforcing the connection between inhabitant and nature.
Client's Comments
For us, ‘Tuath na Mara’ is wonderfully paradoxical: profoundly contextual and strikingly free-floating.
It is contextual in two senses: Firstly it speaks to the built experience of both our families, being the width of a house on the west coast that has been in the family for generations, and having the name and some of the shape of a house built by a Scottish grandparent (‘Tuath na Mara’ equally well in Scots and Irish Gaelic). Secondly it is rooted in the Donegal landscape, or more precisely in the inter-tidal seascape with which it shares its colour and, very nearly, its location. From the sea, it is virtually invisible.
But it is also free-floating, both in the way it sculpts light internally, and in the way its design is part of a cosmopolitan architectural conversation that is above national boundaries. This global-local interchange marks it out as capable of belonging only to the 21st century.
Results
MacGabhann Architects have made, as the client describes, a wonderful modern escape. With integrated reference to vernacular buildings and the landscape, without compromising aesthetics and impressive modern design, I'm confident that this is not the last we'll hear from them in great residential design.

Arkhefield’s Bahaman Eco-Shed Down Under
00/00/0000, 00:00 | Inhabitat
When they were first commissioned to create a “Bahaman” seaside cottage on secluded South Stradbroke Island, Brisbane-based Arkhefield was faced with a few interesting challenges. The design had to be livable all year round, made from materials strong enough to withstand the harsh climate conditions, yet remind its inhabitants of memorable vacations spent on exotic islands. The resulting design stands out as a modern, sustainable interpretation of a Bahaman cottage that capitalizes on the site and celebrates volume but is also capable of isolating, re-orienting and shutting down against inclement weather when necessary.

A Short History of Earthbag Building
00/00/0000, 00:00 | Green Home Building and Sustainable ArchitectureAt first natural materials such as burlap were used to manufacture the bags; more recently woven polypropylene has become the preferred material because of its superior strength. The burlap will actually last a bit longer if subjected to sunlight, but it will eventually rot if left damp, whereas polypropylene is unaffected by moisture.
Because of this history of military and flood control, the use of sandbags has generally been associated with the construction of temporary structures or barriers. Using sandbags to actually build houses or permanent structures has been a relatively recent innovation.
It was an Iranian-born architect named Nader Khalili who has popularized the notion of building permanent structures with bags filled with earthen materials. Actually his first concept was to fill the bags with moon dust! Attending a 1984 NASA symposium for brainstorming ways to build shelters on the moon, Khalili coupled the old sandbag idea with the ancient adobe dome and arch construction methods from his homeland in the
Khalili came up with a further refinement on this building concept on Earth: for a more permanent, shock-resistant structure, why not place strands of barbed wire between the courses of bags, thus unifying the shell into a more monolithic structure?
At first Khalili was filling his experimental bags with desert sand, but then he evolved his idea of “superadobe,” where bags or long tubes of polypropylene bag material would be filled with a moistened adobe soil that would dry into large adobe blocks. In this case the original bag material was merely the initial form and would not necessarily be an integral part of the eventual structure.
Soon after these first experiments, Khalili began publicizing his work through newspaper and magazine articles and conducting workshops and seminars on the techniques that he was perfecting. Many people who read about his work, visited his compound in
Among these “early adopters” were Joe Kennedy, Paulina Wojciechowska, Kaki Hunter and Doni Kiffmeyer, Akio Inoue, and Kelly Hart. I believe that it was Joe Kennedy who coined the more general term “earthbag” to suggest that the bag could contain a variety of earthen materials.
Paulina Wojciechowska was the first to write an entire book on the topic of earthbag building: Building with Earth: A Guide to Flexible-Form Earthbag Construction was published in 2001. This featured some of her early experiments done at Khalili’s CalEarth, along with several other case histories.
Akio Inoue, from
Kaki Hunter and Doni Kiffmeyer (a couple) became enamored with earthbag construction after studying with Khalili, and worked on a variety of projects, both for themselves and for clients. In 2004 they wrote and got published another book,
Kelly Hart (the author of this article) first began experimenting with earthbag building in 1997, after being exposed to the concept while producing his video program, A Sampler of Alternative Homes: Approaching Sustainable Architecture. He later documented his experience in actually building his own home in another program titled Building with Bags: How We Made Our Experimental Earthbag/Papercrete Home. Both of these programs are now available as DVD’s.
In the meantime, Nader Khalili was continuing the promotion of his “Superadobe” technique and eventually decided to patent the idea, which he obtained in the U. S. in 1999, using very general terms that cover using bags made of any material being filled with virtually any material, and combining these with barbed wired between the courses. While having made many public statements that this concept was his gift to humanity, he obviously wanted to capitalize on the potential economic reward.
Many of us who had been engaged in promoting earthbag building on our own were contacted by Khalili and asked to enter into contracts with him in order to continue our work. It didn’t take much research to discover that his patent could easily be disqualified because he had been publicizing his techniques through various media for at least four years before he even applied for his patent. Patent law clearly states that such publicity occurring prior to one year before the patent application would disqualify it for consideration.
So now the door is wide open for anyone to take this concept and run with it, and more people are doing so all the time, all over the world. While Khalili (and most of his students) have focused primarily on using the bags to form large adobe blocks, others have tried filling the bags with a variety of other materials, such as crushed volcanic rock, crushed coral, non-adobe soils, gravel, and rice hulls.
Earthbag building is unique among all other building technologies in that it can be either insulation or thermal mass, depending on what the bags are filled with. This is a very important distinction, because these characteristics of a wall greatly influence how comfortable, economical, and ecological any given system will be.
Safety is of prime concern with all building technologies, and much experimentation and testing has been done to establish guidelines for many ways of building. Khalili has established a relationship with the building department in
In 1995 dynamic and static load tests were performed on several prototypes for a planned
In 2006, at the request of Dr. Owen Geiger of the Geiger Research Institute of Sustainable Building, the Department of Civil and Mechanical Engineering of the U.S. Military Academy at
Despite the success of these tests, earthbag building concepts have yet to be incorporated into the International Residential Building Code. Obviously more enlightened acceptance of the demonstrated viability of earthbag building needs to occur!
It is difficult to know how many residences and other earthbag structures have been made at this point, probably hundreds if not thousands. Many of us have been promoting the technique for use as emergency shelters, and certainly some have been built for this reason. It is easy for folks to accept this way of building temporary shelters because it fits the historical model of sandbag use.
But many of us have also built substantial homes using earthbags, and in the process realized how truly versatile and sustainable the technique is. I wouldn’t be surprised if many of these earthbag homes are still standing long after their conventional counterparts built contemporaneously have disintegrated.
Building with Unbonded Pumice
00/00/0000, 00:00 | Green Home Building and Sustainable Architecture
Dr. Owen Geiger and I have just found that a book published in 1990 in Germany, Building with Pumice, written by Klaus Grasser and Gernot Minke, describes experiments done in the 1970’s at the Research Laboratory for Experimental Building at Kassel Polytechnic College in Germany that have considerable bearing on the history of earthbag building. Most of the book is about the physical properties of pumice, how to obtain and process it, and how to make blocks or walls with pumice/cement, but the fifth and final chapter, titled “Building with Unbonded Pumice,” describes how they began to investigate the question of how natural building materials like sand and gravel could be used for building houses without the necessity of using binders. The use of fabric-packed bulk material was found to be a cost-efficient approach. They used pumice to pack in the bags, because it weighs less and has better thermal insulating properties than ordinary sand and gravel. Their first successful experiments were with corbeled dome shapes (an inverted catenary) which was obtained with the aid of a rotating vertical template mounted at the center of the structure.
1978, a prototype house using an earthquake-proof stacked-bag type of construction was built in Guatemala. They used cotton bags soaked in lime-wash to protect the material from rot and insects. When flattened, the bags measured roughly 8 X 10 cm. Vertical bamboo poles placed on both sides of the bags and interconnected with wire loops gave the stacked bags stability. The bamboo rods were fixed to the foundation and to the horizontal tie beam at the top.
Obviously the concept of constructing homes with fabric bags of mineral material predates Nader Khalili’s earliest experiments by many years, and I was certainly not the first to experiment with filling earthbags with pumice!

00/00/0000, 00:00 | Green Home Building and Sustainable ArchitectureThese new codes include basic passive solar mandates: "When site and location permit, orient the building with the long sides facing north and south. Provide exterior shade for south-facing windows during the peak cooling season. Provide vertical shading against direct solar gain and glare due to low altitude sun angles for east- and west-facing windows."
For renewable energy, the codes says, "Use on-site renewable energy sources such as solar, wind, geothermal, low-impact hydro, biomass and bio-gas for at least 1% of the electric power."
For water conservation, the code says, "A schedule of plumbing fixtures and fixture fittings will reduce the overall use of potable water within the building by 20%, and provide water efficient landscape irrigation design that reduces by 50% the use of potable water beyond the initial requirements for plant installation and establishment."
"Each building shall further reduce the generation of wastewater by one of the following methods: The installation of water-conserving fixtures (water closets, urinals) or utilizing non-potable water systems (captured rainwater, graywater, and municipally treated wastewater
(recycled water)."
For materials to be specified for construction, the following is mandated:
- Select building materials or products for permanent installation on the project that have been harvested or manufactured in California or within 500 miles of the project site.
- Select bio-based building materials and products made from solid wood, engineered wood, bamboo, wool, cotton, cork, straw, natural fibers, products made from crops (soy-based, corn-based) and other bio-based materials with at least 50% bio-based content.
- Employ wood-based materials and products comprising at least 50% of a major building component, such as framing, flooring, or millwork, which are certified by one of five listed sustainably harvested certification programs.
- Use materials made from plants harvested within a ten-year cycle for at least 2.5% of total materials value, based on estimated cost.
- Use salvaged, refurbished, refinished, or reused materials for a minimum of 5% of the total value, based on estimated cost of materials on the project.
- Use materials, equivalent in performance to virgin materials, with post-consumer or preconsumer recycled content value (RCV) for a minimum of 10% of the total value, based on estimated cost of materials on the project.
- Use cement and concrete made with recycled products, fly ash, raw or calcined natural pozzolan, blast furnace slag (as a lightweight aggregate) .
- Select materials for longevity and minimal deterioration under conditions of use.
- Select materials that require little, if any, finishing.
- Select materials that can be re-used or recycled at the end of their service life in the project.
- Select materials assemblies based on life cycle assessment of their embodied energy and/or green house gas emission potentials.
Environmental and health-related items establish specific limits on VOC emission of materials used within the structure, as well as regulate ventilation, CO2 emissions, tobacco smoke, lighting, outside views, and noise transmission.
Additional recommended measures include:
- If feasible, disassemble existing buildings instead of demolishing to allow reuse or recycling of building materials.
- Utilize a Frost-Protected Shallow Foundation.
- Use pre-manufactured floor and roof systems to eliminate solid sawn lumber whenever possible.
I have been advocating most of these measures at www.greenhomebuilding.com for many years now, and it is heartening to see them being officially sanctioned. This is a far-reaching and well-considered attempt by California legislators to establish requisites for living sustainably. If there are going to be building codes, they might as well be green! Yeah California!
