David Hill: Major environmental victory after loophole permitting operations in rare ecosystems is declared “unconstitutional”
Jenna Van Horn's insight:
It's wonderful to see such a incredible victory for protection of the environment and the people of a country that has heavily relied on oil and gas to carry the economy. I sincerely hope that the ruling is upheld.

Is Passive Solar Design Irrelevant?

Is Passive Solar Design Irrelevant? | Permaculture, renewables, and sustainability | Scoop.it
Passive solar design principles are now recognized as being less effective at maintaining indoor comfort than superinsulated buildings.
Jenna Van Horn's insight:

I have to agree with the author of this article. Although the evidence is against passive solar design being effective, I still feel that some aspects would go a long way towards to assisting heating and cooling efforts for a super insulated house.

The Pros and Cons of Cargo Container Architecture

The Pros and Cons of Cargo Container Architecture | Permaculture, renewables, and sustainability | Scoop.it
With the green premise growing in popularity across the globe, more and more people are turning to cargo container structures for green alternatives....
Jenna Van Horn's insight:

The trend of up-cycling old shipping retainers for housing and commercial spaces is one that is gaining massive momentum; and why wouldn't it be? With over 17 million shipping containers in use around the world (https://www.billiebox.co.uk/facts-about-shipping-containers) and each container holding between 160 - 320 square feet, there will be no shortage of supply in the near future for these. However, what is not generally advertised is the amount of energy that need to be extended to render the used containers to be safe for human habitats. According to this article, "The average container eventually produces nearly a thousand pounds of hazardous waste before it can be used as a structure" and that doesn't include transportation, insulating, or final design, just the prep. While I am all for finding innovative ways to reuse, the use of containers for habitats is one trend I don't see keeping up it's momentum.

Nature by Kevin Songer: HVAC Air Intake Covered in Plants - Green Roofs and Living Walls Filtering Air Flow | Permaculture, renewables, and sustainability | Scoop.it
Jenna Van Horn's insight:

An innovative method for increasing air quality. If used in conjunction with a green house, that would allow for reduced carbon emissions, reduced heat island effect, and could provide the employee with a green space for breaks and fresh produce could be incorporated into the cafeteria.

Even Environmentalists Are Beginning to Grumble About Germany’s Solar Boom

Even Environmentalists Are Beginning to Grumble About Germany’s Solar Boom | Permaculture, renewables, and sustainability | Scoop.it
It’s been a long, dark winter in Germany. In fact, there hasn’t been this little sun since people started tracking such things back in the early 1950s. Easter is around the corner, and the streets of Berlin are still covered in ice and snow. But spring will come, and when...
Jenna Van Horn's insight:

As a new resident of the Bavarian state of Germany and passionate student of sustainability, I find that the article accurately portrays the setting for solar power in Germany. The countryside is peppered with solar farms and most rooftops in this part of the country sports at least one row of photovoltaic panels. Even my parents, whom only have an interest in solar based on what it can save them on their electric bill, commented on the amount on their quick trip through the region last summer.

 

So the dropping prices of photovoltaic panels should be a cause of alarm for the mega corporations of the past, because if solar panel are so suffused into the German way of thinking, then lower prices and better products mean that the deluge is far from over as Germany tries to reach its aggressive energy goals. In addition, the general trend of sustainability and permaculture is that the power is put back in the hands of the people to control their livelihood, whether it is growing their own food or producing their own power.  Companies that are affected need to adapt, which is not new knowledge. By tweaking the infrastructure in place, companies could offer support for existing panels, as well as offer “leasing” programs of sort so that as panels become more efficient they could replace the less efficient model. Older models could then be donated to developing nations to help push sustainability matters in their own countries and help deal with the growing pains of development.

 

Lowered cost of production and increased efficiency should also act as a catalyst for research into alternative methods of clean and renewable energy. As mentioned in the article, many current renewable methods of energy collection have inherent flaws; solar underperforms in cloudy weather, according to https://www.wind-watch.org/faq-output.php windmills spend about 60% of the time not producing energy, and hydro-electric dams have adverse consequences on the ecology of the surrounding areas. If developers could find a way to combine the best of multiple approaches instead of independently focusing on improving a particular method, then environmentalist could better divide the subsidiaries and have a larger return on the production.

Solar-Wind Lighting Technology

Solar-Wind Lighting Technology | Permaculture, renewables, and sustainability | Scoop.it
Grenlec continues to explore renewable energy options for a range of applications.
Jenna Van Horn's insight:
I have alway been a firm believer that technology, as demonstrated in nature, will work best if diversified. By using both wind and solar power in a singular technology (in this case a street lamp), you can cover the flaws of the individual and the likelihood that the technology will remain fully functional is extremely high.

Untapped Market in Smaller Green Retrofits - Urban Land Magazine

Untapped Market in Smaller Green Retrofits - Urban Land Magazine | Permaculture, renewables, and sustainability | Scoop.it
While many "green" building techniques have become the norm for new construction, panelists at a recent ULI forum say significant opportunities exist for upgrading or retrofitting buildings with green systems and technology.
Jenna Van Horn's insight:
This article provides some excellent points about the value that is being placed on high performance buildings as not only a way to attract tenants but as a recruitment tool as well. Employees want to work for businesses that provide open and airy workplaces and employers should want it as well. It has been shown to increase productivity, and that is before the savings that occur due to less usage of water and electricity.

How to beat extreme heat: Strategies for combating the urban heat island effect — Broken Sidewalk

How to beat extreme heat: Strategies for combating the urban heat island effect — Broken Sidewalk | Permaculture, renewables, and sustainability | Scoop.it
[Editor’s Note: This article was cross-posted from engineering firm ARUP’s doggerel blog, covering cities, resiliency, and the future. Follow along with ARUP on Twitter & Facebook.] Four years ago, Louisville, Kentucky, awoke to an alarming urban trend. This forward-thinking southern city—recently ranked as America’s most livable by the U.S. Conference of Mayors—had landed at the top of
Jenna Van Horn's insight:

This article confirms what has been an ongoing narrative for many major cities that have been forced to reexamine the impact of human behavior on the places where the most population growth is happening. Like many sustainability measures, battling the heat island effect will be beneficial to many other of the city living challenges, such as pollution control and storm water runoff, and if tackled by a diverse set of options, the cities implementing them will hopefully see the potentially life saving effects sooner rather than later.

Forces of globalization, urbanization and technological advancement are transforming the definition of a ‘successful’ city.
Jenna Van Horn's insight:

As federal and state governments become bogged down by bipartisan ideological differences, budget deficiencies, and an general unwillingness to work towards a more sustainable future, it turns to cities to find the solutions that will keep their denizens hale and hearty.
