Pulse Technology: Micro-monitoring Your Energy Use for Conservation

How cool would it be to receive updates on the amount of energy used every time you turn on a light, open a window, or turn on the heat?

Thanks to Pulse, a digital tool developed by Investa Sustainability Institute and Green Buildings Alive, electricity usage per building can be assessed and uploaded directly to the web. Pulse data feeds update every 15 minutes, and create summaries of daily overall consumption.

“What we are doing here might look simple, but the practice draws from nearly a decade of measuring and monitoring what really makes a building greener. We’ve learnt that sustainability in our sector doesn’t have to mean a fancy façade or expensive technology. Real, measurable energy savings are the bedrock of the radical changes on the horizon for cites worldwide,” says Craig Roussac, director of the Investa Sustainability Institute.

Pulse technology aims to influence behavioral change and raise energy awareness among building occupants. Already, large corporate buildings have the ability to compare their energy usage with that of competitors as well as the increased involvement of employers in ensuring a greener work space. Pulse can also uncover and report costly energy anomalies automatically. It doesn’t get much more convenient than checking your automatically reported energy usage online.

“green” vs. “sustainable”… what do they actually mean?

The words “sustainable” and “green” are both buzzwords often used interchangeably. Up until I took an Environmental Studies class last semester, I wasn’t completely clear on the distinctions between them. From a designer’s point of view, however, the distinctions are critical to understand an otherwise hackneyed movement in architecture and design.

First, let’s look at “sustainable.” A sustainable product lowers pressure on the environment by using renewable or sustainably produced materials. A sustainably produced material, in turn,  is one that doesn’t pollute, destroy or erode the environment in which it is gathered or produced, and one that doesn’t permanently reduce the supply.

“Green,” on the other hand, refers to products that function so efficiently and/or strategically as to cause reduced or minimal impact on the environment. Specifically, green design minimizes waste, fuel, and other potentially unnecessary resources that go into construction. Usually, buildings are “green,” but not sustainable. However, there are a few out there that are both. Oberlin College’s Lewis Center, for example, employs its own water treatment system, features scores of solar panels on its roof, and uses geothermal wells to heat and cool the building.

Of course, the term “green” has also come to be known as something too that’s politically liberal, but here at KSDG, we believe that caring about the health of the environment and the people in it shouldn’t be restricted to one political party or another, don’t you?

how to collect rain from an entire city

I’m a member of the Berkeley chapter of Global Architecture Brigades, and for our most recent design competition for a medical center in Honduras, it was my responsibility to research rainwater collection systems for implementation on our building.

In general, rainwater collection systems involve directing rainwater to a filter, and then to a cistern which is usually located underground, and that pumps filtered water throughout the rest of the building. Pretty simple, right? So imagine the possibilities of a city-wide rainwater collection system!

Sabrina Faber, developed just that for Sana’a, Yemen, a city plagued by frequent water shortage, and of which she is a long term resident. Her design, which won the 2011 Phillips Living Cities Award, captures water from the flat roofs that are of the dominant architectural style in Sana’a, and siphons it off to underground tanks. Watch the video to learn more about Faber’s RAIN System.

a vertical forest inside a city of gardens: “bosco verticale”

I’m fascinated by something called the Garden City Movement of the early 20th century, and was intrigued when I heard about this similar sustainable urban restructuring plan in present day by Stefano Boeri. Currently under construction in Milan, “Bosco Verticale” is comprised of two apartment towers with giant cantilevered balconies that accommodate a vertical forest.

The forest includes approximately 900 trees as well as a plenitude of shrubbery and other floral vegetation, and has a flattened footprint of about 10,000 square meters. Each apartment has a balcony enveloped by a lush garden which is irrigated by  filtered grey water produced by the building.

Not only have solar and wind energy systems been built into the structure to increase energetic self-sufficiency, but these forested patios also create microclimates that require less energy to heat and cool. These microclimates are a result of the forest’s humidity and oxygen production, carbon dioxide and dust absorption , and protection from direct sunlight. The biodiversity of the plants within this forest in addition to the attraction of birds and insects hope to create a self-sufficient ecosystem. Bosco Verticale is the first element in Boeri’s urban project BioMilano, a proposal for a green belt around Milan that would restore 60 abandoned farms on the outskirts to community use.

how do you spell green revolution? C-o-n-X-t-e-c-h

When you hear of a 101,000 square foot, steel reinforced data center built in nine days, you’d think it unfeasible. Then when you hear about a 10 story steel tower built in three days, you’d have to think “impossible.” These two extraordinary feats have one thing in common: ConXtech, a Hayward-based technology company that manufactures prefabricated steel space frame systems.

Their modular systems are comprised of wide flange beams, HSS (or box columns,) and ConXR or ConXL connectors, allowing for mass-customization and configuration. With a ConX system, architects can select the structural grid early on in the design process, saving time that otherwise would have been spent designing around certain structural constraints.

Dimensional accuracy also enables various architectural elements such as curtain systems, stairs, and balconies to be attached to the framework. ConX systems also allow for seismically sound, higher buildings as a result of their unique moment connection with bolted collar systems. ConXtech’s cost effective systems have already been employed for projects at Burning Man (where five people assembled a ten story building in five days in the middle of the desert), Stanford Law School, and the Coronado U.S. Naval Base.

What makes ConX systems so green is their decreased overall tonnage, collapse resistance, and energy and material efficiency. I guess this just goes to show that with maximum efficiency, anything is possible.

Cool, huh?

KSDG volunteers at the san francisco food bank!

Hello again!

Happy KSDG employees sorting fruit at the San Francisco Food Bank!

Did you know that not only is KSDG an awesome leader in sustainable architecture, investments, and living but also incredibly passionate about helping the community? The most recent example of the company lending a helping hand is a recent trip taken on February 24th to the San Francisco Food Bank. The group spent the day sorting for fruit for different churches, food kitchens, and other groups around the Bay Area.

Volunteering at the Food Bank is a simple way to make an impact on the community. Dedicating just one day to helping sort food is an invaluable contribution. One of SF Food Bank’s mottos is that “hunger shouldn’t be an option.” Every day, the city of San Francisco sees people who skip meals and eat less well because they must save food for other costs. Choices like these hinder the health of the individuals within our community. To solve this problem, the Food Bank collects thousands of pounds of foods, which are shipped to different Food Bank locations where the products and sorted, shelved, and packaged by volunteers. The food is then delivered to over 450 nonprofit locations, serving over 225,000 people a year.

Fruit at the San Francisco Food Bank waiting to be sorted by our KSDG volunteers.

Being a volunteer for the San Francisco Food Bank is an inspiring experience. Helping to sort, shelve, and package healthy food for those in need truly makes an impact. Over 22,000 volunteers contribute thousands of hours to helping the Food Bank each year, which translates to a distribution of 43,5 million pounds of food – equivalent to 93,000 meals a day. If you or your organization are interested in working at the food bank as a group like KSDG, you can visit this website to learn more about the available volunteer schedule.

Happy sustainable living!

futuristic sustainable living with the hover home!

Hello blogosphere!

Hover House 3 is an innovative model for sustainable living.

A few weeks ago, I wrote about the FLOAT House – an innovative design that allows homes to “float” in cases of flooding and sea level rise. While making your house able to float on water is cool, how about a hovering house? Glen Irani Architects has worked to design the aesthetically flawless and energy efficient “Hover House 3.”

Located in Los Angeles, the goal of the house is to hover the building structure over outdoor living space in order to maximize the amount of outdoor square footage a property has in an tightly fit urban location.

These hovering structures also reduce indoor floor area significantly, which help lower building costs and consumption of dwindling building resources. The home also boasts large windows, photovoltaic panels on its roof, and many other sustainability-improved technologies.

Happy Sustainable Living!

Flushing Away the Environment: How Much Damage Do Toilets Cause?

How much water do we each day day, each year? This graphic gives you the answer, and break it down by specific use (Shower, faucet, toilet, clothes washing, other)

Hello Everyone!

The other day in the KSDG office, we were chatting about water use and how crazy it is that we can use so much water so quickly! Things like toilets, showers, and sinks use way more water than necessary. And there’s not a lot of clean water left on the planet.

After thinking about the thousands of gallons of water we waste each day, I decided to look into researching exactly how much water we really do use during our day-to-day activities. Using the data I found, I made the below graphic to illustrate how dependent on water we are for various daily activities.

Who would think that a simple flush could cause so much water to literally go down the drain? The most astonishing part of this graph is the fact that we use so much water for our toilets!

It’s not something we like to talk about or think about–toilets are a taboo subject, but if we’re going to really make a difference environmentally, we have to be willing to face each piece of the equation in sustainability. When building sustainable homes, KSDG is faced with the challenge of ensuring that every part of the home meets sustainable standards – and green-friendly toilets are definitely something KSDG considers when designing homes. We’re on the lookout for the simplest, most aesthetically pleasing solutions to these issues.

Happy sustainable living!

what’s up? high rise renovations

High Rise Buildings in Toronto, Ontario

Renovations at home can be daunting projects, but imagine renovating a building that has dozens of floors. The biggest skyscraper in the world is the Dubai Tower, and it actually has 162 stories!

The Energy Saving Trust company in the UK and Scotland compiled some advice for high rise renovations.

I never knew that gas heating, humidistat controlled extract fans, and lesser windows sizes would be a good choices for skyscrapers. The bring up some interesting suggestions, that are specific to large buildings.

Read about floating floors, thermal bridges, and pitched roofs in the original article here.

Until Next Time,
