Every refrigerator and air conditioner contains chemical refrigerants that absorb and release heat to enable chilling. Refrigerants, specifically CFCs and HCFCs, were once culprits in depleting the ozone layer. Thanks to the 1987 Montreal Protocol, they have been phased out. HFCs, the primary replacement, spare the ozone layer, but have 1,000 to 9,000 times greater capacity to warm the atmosphere than carbon dioxide.
In October 2016, officials from more than 170 countries met in Kigali, Rwanda, to negotiate a deal to address this problem. Through an amendment to the Montreal Protocol, the world will phase out HFCs—starting with high-income countries in 2019, then some low-income countries in 2024 and others in 2028. Substitutes are already on the market, including natural refrigerants such as propane and ammonium. [Source: https://www.drawdown.org/solutions/materials/refrigerant-management ]
A building envelope is comprised of the components that make up the shell of the building. The components separate the exterior from the interior of the building, and are designed to meet or exceed the needs of the specific application. The building envelope may also be described as what separates the interior areas that are temperature controlled (conditioned) space from exterior unheated (unconditioned) space. To break it down any area that is heated or air conditioned is considered a conditioned area where as any area that isn’t would be considered an unconditioned area. The building envelope must be designed with regard to climate, ventilation, and energy consumption within the building.
The many functions of the building envelope can be separated into three categories:
Support (to resist and transfer mechanical loads)
Control (the flow of matter and energy of all types)
Finish (to meet human desires on the inside and outside)
The Climate Crisis is a Health Crisis (Graphic from The Climate Reality Project)
The world’s leading scientists agree we must slash emissions by 2030 and keep global warming below 1.5 degrees C to avert a truly dangerous future. Carbon pollution poisons our air, water, and soil, threatening our health.
When we protect our planet, we protect ourselves. The Climate Reality Project is calling on the world’s leaders to ACT NOW.
Tesla’s solar roof is gradually rolling out to more homes. A new set of photos shared this week show a new installation at twilight, complete with cutouts for chimneys and other features. The design looks impressive, and it’s one of the few sightings seen on social media since the first installations appeared early last year.
The roof was shared by a now-deleted Twitter account, which was subsequently posted to Reddit by a user called “Potatochak,” where it received over 3,000 upvotes on the Tesla subreddit. The depicted tiles appear to be the textured variety, but the company also offers a smooth style depending on cosmetic appearance. Tesla recommends a normal house uses a mix of 35 percent solar tiles at $42 per square foot to 65 percent “dummy” tiles at $11 per square foot, resulting in an average price of $21.85 per square foot, but it’s unclear how many times are operational in these images.
It was great meeting @threesquaresinc at 24 Hours of Reality 2018 at Los Angeles Historic Park earlier this month.
As it so happens, film productions have a nasty reputation for wasting and improper disposal of materials. Enter Three Sqaures Inc.!
Each day of production they held a meeting (as seen above) where they debriefed the production crew on how to properly dispose of their waste on set.
We also had set up 4 options for dumpsters: compost, landfill, recycling and construction/demolition (as seen in photos). At one point when I found catering dumping excess food waste (non-meat) into the landfill I asked them to use the compost bags and use the compost dumpster. They replied that they green compost bags tended to tear open while they carried them so they used garbage bags instead. I offered the idea that they could use a milk crate to transport the compost bags and thankfully they listened and the new plan worked minimizing any spillage.
It was great to have the support of Three Squares Inc to help make our set as green as humanly possible!
Imagine if every production set were able to properly sort their waste–it would surely reduce the environmental impact of the modern entertainment industry.
Energ.io (@greenerg.io) of Soﬁa, Bulgaria has crowdfunded a Solar Farm which produces six hours of green energy per day. They produce 100% green energy and use that power to support the #blockchain Check out their bio to help support their cause!
Social Plastic Foundation’s mission is to rid the oceans of plastic and provide a lifeline to communities in need. They help some of the poorest communities globally to collect plastic before it becomes problematic ocean plastic. The Plastic Bank then sell this Social Plastic onto companies to use in place of virgin plastics. Social Plastic Foundation is a charity that provides ocean plastic & recycling awareness, along with training and support.
The Social Plastic Foundation is a charity established to support, enhance & grow the world’s Social Plastic recycling ecosystems. These are recycling communities in developing regions that utilize The Plastic Bank’s recycling reward & incentive platform to improve livelihoods while preventing ocean plastic.
The Social Plastic Foundation encourages us to help to increase the reward that recyclers receive. They believe this is how we make plastic waste too valuable to enter the ocean.

Be the Change books are set to be a collection of four books, each with an animal protagonist. The first book sees a little tiger shark called Finn lead the way. His tale shows the impact of plastic in the ocean and paints a rather grave picture of the reality for marine wildlife. While the story has a wonderfully positive ending, its message really connects with the reader. The beautiful illustrations are also sure to draw in any young person.
It’s really positive to see people like Stevens trying to make a change. Books like these are a fantastic way to engage and interest youngsters, especially if they become part of the school curriculum.
100% of the profits from this book will be split between the organizations: “GREENPEACE” and “SOCIAL PLASTIC”.
Find out more about Be the Change books and support her initiative by buying the new Finn the fortunate Tiger Shark book from Amazon.

Why not get out to the beach or a state park and do some good for the planet?
The Drawdown EcoChallenge is a fun and social way to learn about and take action on the 100 climate solutions featured in the seminal work of Paul Hawken “Drawdown.”
From April 4-25, individuals and teams from around the world will take part in simple daily activities to reduce their carbon footprints and delve into the world’s most substantive solutions to global warming. At the end of the Challenge, the teams with the most points will win great prizes, including copies of Drawdown and a one-hour video session with Paul Hawken!
The EcoChallenges are broken down into these sections (with an added note of current participants):
LAND USE (1260)
ELECTRICITY GENERATION (1751)
WOMEN AND GIRLS (1392)
BUILDINGS AND CITIES (1598)
Executive Director of Drawdown, Hawken states “All of life is comprised of self-organizing systems and the Drawdown EcoChallenge is exactly that—people coming together to share, learn, support, imagine, and innovate for a better world. We are honored to be a part of this significant and brilliant initiative.”
