Tallest Wooden Tower in the World is Almost Complete

ext


Say what you will about wooden construction, it is sustainable. So it's great that even large structures are now being built out of wood. One awesome example of this type of architecture is Brock Commons, a University of British Columbia student housing tower. It will rise to an impressive 174 ft (53 m) and will be the tallest wooden residential tower in the world once it is complete. Which it very nearly is.


int


It took just 66 days to build the wooden tower. It's not quite finished yet though, but once complete it will contain 33 four-bed rooms, and 272 studios, so the 18-floor tower will be able to accommodate 404 residents. The tower was designed by Acton Ostry Architects.

The structure consists of 16 floors of five-ply cross laminated timber (CLT) floor panels, and has a steel-framed roof, as well as a few concrete sections, namely the base and stairwells. The façade of the tower is made of prefabricated panels that had the windows pre-installed. These panels contain 70 percent wood-based fibers with steel stud framed sections, and form a high-pressure laminate cladding.


The construction went remarkably quickly. At first they managed to build one floor per week, but were able to go faster after that, building two or more floors per week. Not including the concrete sections, they've been able to complete the entire structure in just over three months, which given the size of the tower is quite remarkable.

The Brock Commons residence was also designed according to LEED Gold certification standards, and will receive this certification once it is completed. They estimate that it will be completed in May, 2017, which is four months ahead of schedule. They are currently installing the steel roof, which they hope to complete in a couple of weeks.

Home Insulated With Pumice Stone

ext


Advancements in technology and science have revolutionized architecture and construction, but often to the detriment of traditional building methods. Over the ages, cultures around the world developed construction methods that best fit the climate they live in, and perhaps it is time to go back to the basics. That's exactly what architects Luis Velasco Roldan and Ángel Hevia Antuña from Ecuador thought. They designed a prototype of a home built using traditional methods once used in the area, and materials that were sourced locally.


int


Their main goal is to explore the energy efficiency of building in a regionally relevant way. One of the reasons they embarked on this experiment was that buildings in this, and other South American countries that were built using modern construction methods and materials, such as concrete, steel sheets and fiber cement, have proven to offer periods of thermal discomfort which could have been eliminated had the structures been designed in line with traditional knowledge.

The house they built measures only 524 square feet (49 sq m), possibly due to the fact that it's only a prototype. The used traditional methods and materials in designing and constructing it, including pumice stone for insulation. Pumice stone is riddled with air pockets, which work to insulate the home, and the stone itself acts as a thermal mass capable of regulating fluctuating exterior temperatures. Due to this, the interior temperatures of the home are a constant 68 to 70°F (20 to 21°C) year round, even when outside temperatures drop to 53°F (12°C). The home also features a green roof, under which they also installed a layer of pumice stone for insulation as well as drainage.


insulation


The home features a living room, kitchen, dining area, bedroom, bathroom and office. They used Ecuador laurel for exterior cladding and eucalyptus wood for framing the home, both of which are abundant in the area. Passive solar heat gain was one of the main design considerations, so the home also features a number of floor-to-ceiling windows and sliding doors, which lets in plenty of natural sunlight, aids ventilation and brings the inhabitants closer to nature. The bedroom also features a glazed corner as well as a skylight, so the room can also be used as a solarium.

The home was also built in a way that allows it to be disassembled quickly and easily. This is because they plan to move it around the country to test its energy efficiency in various climates. They are also planning on equipping it with automated open-source software energy management systems, such as motorized shutters to block out the sun or let it in.

This is a great experiment and very beneficial too, since going back to basics might be the best way to achieve a sustainable future.





A Well Insulated Tiny Cabin

ext


While living full time in a tiny home may not be for everyone, it is undeniably a very sustainable housing alternative. Besides, tiny, easy to assemble structures have many uses, such as a home office, guesthouse, yoga studio or cabin. The Little Cabin Company of British Columbia recently unveiled just such a versatile creation, which can also be a great glamping alternative for colder areas, due to the fact that it's very well insulated.


The cabin is called Cobby and measures 104 sq ft, with a footprint of 12' by 11'3”. They are insulated using blown recycled fiber, and can withstand even Canada's extreme winters. The entire cabin is constructed using locally sourced materials, with the siding made using sustainably harvested cedar. While they can be hooked up to the grid, the company also offers a solar package to power the LED lighting and other necessary appliances.


insulation


Due to the superb insulation, very little energy is needed to heat the cabin. They are already fully assembled when they arrive on site, and can be installed in about two to four hours. They also do not require a poured concrete foundation.

The roof of the cabin has a very unique shape, and it is such so that it can handle increased snow loads and offer extra interior space. Given the high ceiling, the interior feels a lot more spacious than it actually is.


The cabins are pretty expensive though, and the one pictured above costs $19,200. However, according to the company, you can get one for less, depending on the level of add-ons and customizations. Apart from opting for the solar power package, future owners can also request a larger cabin or one with a deck and a washroom.

“Climate change is real, it is happening right now. It is the most urgent threat facing our entire species, and we need to work collectively together and stop procrastinating. We need to support leaders around the world who do not speak for the big polluters, but who speak for all of humanity, for the indigenous people of the world, for the billions and billions of underprivileged people out there who would be most affected by this. For our children's children and for those people out there whose voices have been drowned out by the politics of greed.”
-Leonardo Di Caprio spoke these riveting words during this Oscar accepting at the academy this year. 2015 recorded as the hottest year in the history of the modern world, scientists and experts calling for a united stand of the leading Governments of the world to tackle the problem collectively.




Is Climate Change real?

Irrespective of which side of the argument you are on “Climate change” is indeed a real threat, and there is evidence that the world is facing ramification as a result. The wildfires of Australia or extreme drought conditions in Africa last year have been attributed to climate change. Heatwaves that swept every continent in the world last year is yet another proof that climate change is happening, and there is an impending need to address this problem on a global platform.

How is Climate Change linked to Business & Industrialization?

The world has evolved from an agrarian based economy to an industrialized one to a more technology-driven one. During the industrial period, energy consumption was the mainstay of the economy. Although this ear brought with it riches and gave rise to a consumerist society, the industrial revolution is often cited as the mean reason for the downward spiral of earth's relationship with ecology and humans.


A Drive towards Sustainable Business Trends

cop-parisAs the world's leaders met at 2015 United Nations Climate Change Conference in Paris to reach a global agreement to reduce climate change, time has also come when entrepreneurial leaders of the world have to think about most sustainable ways to conduct business.


Thankfully, in the modern ear, business owners are more mindful of this and are aware of how business operations can harm the environment. Owing to several small and medium sized enterprises are adhering to norms and work culture that is sustainable and environmentally friendly. For instance, emails to a large extent have eliminated the use of papers in office spaces. Advancement in technology has also enabled businesses to minimize the use of paper as e- documents, e-bills, etc. take precedence.


Even work culture and place of work are undergoing an overhaul to reduce carbon footprints on the planet. There is an increasing drive towards designing eco-friendly buildings and office spaces that focus on water and energy conversation. The design philosophy of these buildings promotes rainwater harvesting, maximum incorporation of natural lighting and use of recycling materials. Green buildings and architecture are gaining popularity and eventually the cost involved in constructing such spaces will come down.

The onslaught of technology has not just driven greater business prospects. It also has allowed businesses to function in a more sustainable way. Modern businesses have no limitations and people work across geographical boundaries in the most efficient manner. Thanks to this advancement, business video conference services like BlueJeans, allows individuals and business associates to connect with one another without a glitch.

This method of communication also works well for people who perform professional duties from the comfort of their home. In the coming years, this trend is also expected to catch up. In most major cities in the world, peaks hours of the day which is usually the time when people are getting to or getting off work adds to pollution in the city. If only more and more people work from home rather than commute to work in their cars or public transport, the emission of carbon in the environment can be significantly reduced.

Using Grasscloth and Natural Wallcovering for Eco-Friendly Decor

 


Our homes are one of our primary outlets for self-expression. Whether we are entertaining guests or simply welcoming friends and family, our home decor says a lot about who we are and the type of atmosphere that we wish to present. For those with eco-friendly or earth-based style preferences, finding wallcoverings which project your personal style can sometimes present a challenge. Fortunately, there are a number of grasscloth and natural wallcovering options which will flatter any living space while complementing your home's existing eco-friendly style.


grasscloth_wallpaper


In case you are unfamiliar with these products, grasscloth wallpaper is a type of wall covering which is created by weaving dried grasses together and affixing them to a paper backing. Based upon the types of grasses used, it comes in a variety of colors and patterns, and with textures varying from fine to coarse. Because it is crafted from sustainable, natural materials, grasscloth wallpaper is considered an environmentally-friendly option for both homes and commercial spaces.


Note, however, that there are some factors that you should consider when choosing grasscloth wallpaper. The first is that because this is a natural product, it varies in color and pattern. That means you will not be able to perfectly match the rolls to one another. The result is visible seams which can be disconcerting to those who are used to flawless wallpaper patterns. Also, note that you should not use grasscloth or other natural wallpaper in smaller bathrooms or any space in which humidity might be a problem.


natural_wallpaper


Most varieties of grasscloth wallpaper feature a single piece of seagrass held in place by a thin cotton thread, which is attached to the paper backing via a light adhesive. This means that grasscloth wallpaper is susceptible to damage if placed in a high traffic area. While grasscloth makes a lovely wallcovering choice for many homes, you should consider your space itself before making the grasscloth choice.


For spaces in your home for which grasscloth simply is not well-suited, there are a great number of designer wallpaper options from which you can choose. Options vary from vintage to modern styles, and textured options provide a great way to add depth to any living space. Choose a simple floral pattern or a unique color scheme to suit your home's decor. Best of all, most wallpapers are suitable for any room, and provide a beautiful alternative to natural wallcoverings in the high-traffic and potentially humid parts of your home.


grasscloth_wall_designWhether you choose a grasscloth or other natural wallcoverings, you should take your time in making your selections. Unlike artwork, mirrors or other decor items, wallpaper of any kind is not easily interchangeable. Therefore, you should choose a pattern which does not overpower your space and can accommodate a variety of decor pieces should your preferences change over time. With a respectable time investment, you are sure to find something which will bring beauty to your home while showing off your personal style.

Modern Passive House

ext


Passive homes tend to be a little boxy and unappealing, which is probably the reason they haven't caught on as much as they could. So it's nice to see companies finding ways around that. One such example is certainly the Cousins River Residence, which was designed by GO Logic of Maine. This firm has been making prefab and passivhaus homes for a while now, and the simple elegance of their designs sets them apart from others.


side


The Cousins River Residence is located in Freeport, Maine. It measures 1600 square feet designed and was built to Passivhaus standards. It is very well insulated with the foundation having a rating of R35, the wall R50, and roof R80. It was also fitted with high performance triple pane German windows, which provide 50% solar heat gain and have a rating of R8. The home also features a heat recovery ventilation system that boasts of an 88% efficiency. The shell of the home is airtight and provides 0.5 air changes per hour at 50 Pa. The home is also near net-zero, and features a rooftop mounted 4.6 KW Photovoltaic array, which takes care of the remaining energy needs.


The specs are great, but what's also very impressive is that the home is modern architecture at it's best. The shape of a home is simple enough to blend in seamlessly in any environment, and the color palette they chose is mostly whites and naturals. The single story home features a large living and dining area, with a spacious kitchen at one end. One of the walls of this area is covered by glass doors that let in plenty of natural light into the home, which is something not often seen in passive homes.

The home also features a wooden deck, a screened-in porch as well as a covered walkway. One of the main aims the designers had when planning the home was to provide freedom of movement both inside the home, and between the interior and exterior. They also designed it so that it is easily accessible for both the young and the old, since the current owners plan to spend a long time living in it.
