How A Blockchain Token Can Scale Renewable Energy

September 04, 2017

By: Christophe Jospe

What is a blockchain?

The hype about blockchains can be illustrated by a 2010 purchase of 2 large pizzas at $25 using 10,000 bitcoin, the first currency built on a blockchain. At today's prices, the same person could have bought more than $40 million worth of pizza. A common misconception held by people who do not work or invest in the ballooning field of blockchain and digital or "crypto" currencies is to consider bitcoin and blockchain synonymous. They are not. A blockchain is simply the underlying technology infrastructure that, among other things, creates bitcoins.

At the core, a blockchain is an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable, immutable and secure way. Once something has been recorded in a blockchain, it is there forever and cannot be changed. One way to think about this technology is to compare it to the transmission control protocol and internet protocol (TCP/IP). In simple terms, TCP/IP is what makes the internet run by creating rules that can move data around. Most users don't even know about it or care to understand the mechanics. Internet users just know that when they have web-compliant devices, they can do more. Blockchain exponentially improves this framework by building an a more secure and efficient way for transactions to occur between anything connected to the internet. Slowly at first, blockchain applications will come into our lives, and over time, replace TCP/IP entirely. The magic will happen under the hood.

Urban Heat And Urban Design — An Opportunity To Transform In NYC

July 18, 2017

By: Joyce Klein-Rosenthal + Jeffrey Raven

How can planners and designers work with large urban centers to prepare for the adverse impacts of climate change, while also adapting to current climate variability and extreme weather events? With a substantial expected increase in daily average temperatures in coming years, mid-latitude cities such as New York are also expected to experience more frequent and intense heat waves (NYCPCC, 2015; USGCRP, 2016).

How Passive Houses Took Over Brussels

May 01, 2017

By: Arnaud Brohé & Thomas Huberland

The Brussels Capital Region has experienced an energy revolution in the last ten years, transforming it into a lodestar in the passive house movement.

As early as 2010, the European Union issued the nearly zero-emissions buildings directive (or NZEB directive), triggering the movement toward low-emissions buildings in all Member States but giving them the freedom to follow their own path toward the implementation of the directive. Prior to the NZEB, Brussels (Belgium) launched a contest for exemplary buildings starting in 2007 to generate momentum around sustainable buildings by granting subsidies to construction projects exemplifying outstanding energy performance, architectural quality, low environmental impact, and scalability. In total, between 2007 and 2013, 253 projects received grants for an amount of €36 million. However, there was still a long way to come close to the NZEB target and a bold move was required for the Belgian capital city, where 70% of the energy consumed is used in buildings that are rather old: 90% of them were built before 1980. Nonetheless, the Brussels regional government saw an opportunity to become a European leader in building energy performance under those challenging circumstances and started working on a new legislation for the 400,000 square meters (4.3 million square feet) built every year in the heart of Europe.

Start To Prepare Today For Adopting Passive House Tomorrow

March 01, 2017

By: Mark Ginsberg with J Russell Beaumont

The City of New York has a binding goal of 80% carbon reduction from 2005 levels by 2050. Because buildings consume 75% of energy used in New York City, creating more energy-efficient buildings will be essential for meeting this goal. Mayor de Blasio has pointed to the Passive House (PH) standard [1] as one of the few building energy standards capable of delivering the results to meet carbon reduction goals.[2] PH also creates resiliency by creating buildings that are less dependent on heating and cooling systems to maintain suitable indoor temperatures[3] While PH or an equivalent will likely be incorporated into the City's building codes, making this transition happen smoothly requires planning.

Almost Unnoticed, Flat Electricity Demand Is Crushing U.S. Carbon Emissions

January 11, 2017

By: Charles Komanoff

In a stark change from the last century, U.S. electricity usage has barely budged since 2005. The flattening of power production is a big but unheralded reason that carbon emissions from the U.S. electricity sector have nosedived.

In a December 2016 report, I estimated that CO2 emissions from U.S. electricity generation in 2016 will be 27 percent below the baseline level from 2005. This means the power sector is now more than four-fifths of the way to the 2030 goal in the Obama administration's Clean Power Plan, to cut electricity emissions by 32 percent.

How Mortgage Lenders Can Boost Sustainability

November 02, 2016

By: Elizabeth Derry

If you're like me then you've spent some serious time contemplating society's inertia of energy efficiency and carbon reduction. At summits and roundtables, practitioners, myself included, eagerly debate the viability of the newest "emerald bullet," whether it be new tech, codes, or policies that will finally catalyze large scale energy reduction. But what if the key to our low carbon future isn't something new, but something old and familiar, and as ubiquitous to American life as Sunday night football and pumpkin spice lattes?

A Green Systems Approach for Affordable Housing

Affordable and supportive housing organizations in New York City have an unprecedented opportunity to save money by greening their existing buildings. This is big news for a sector that — as a matter of mission and regulation — cannot increase rents to keep up with rising utility and fuel costs.

It's Taken 500 Years For Corporate Environmental Reporting To Be On The Edge of Maturity

May 10, 2016

By: Jon Lukomnik

We're on the eve of a new dawn in environmental reporting by companies and investors. Some may think that's a bold prediction. Just a few months ago Ernst & Young and the Investor Responsibility Research Center Institute concluded that only slightly more than half of large, publicly-traded American companies even list climate change as a risk. And, for those that do, "disclosures often are generic and do not provide clear, concise and insightful information... a listing of generic risks."

So why do I think it's about to change? First, there is now a body of information reported and able to be analyzed. Second, mainstream investment houses like Goldman Sachs are building billions of dollars in investment products that rely on environmental data. They are not about to let disclosure backslide. Third, heavyweight members of the financial establishment — including Bloomberg LP founder Michael Bloomberg, former SEC Chair Mary Schapiro and Bank of England Governor Mark Carney — are committed to making it happen.

Passive House Emerges in New York: Effective and Affordable

March 10, 2016

By: Ken Levenson, A.I.A.

At long last climate science, public policy and effective remedial actions are coming into growing alignment and Passive House is amassing real-world validation as a powerful tool to achieve needed results. Here's what's been happening.

The science of climate change is now strong enough to alarm even the normally complacent. As Justin Gillis reported in The New York Times recently, scientists now believe runaway global warming could likely require the abandonment of our coastal cities in the 22nd Century and beyond. The constituent horrors of such prospects are simply magnitudes beyond anything humanity has faced in history.

Actively Passive

January 13, 2016

By: Richard C. Yancey

Passive House startled me. Despite working for the nonprofit Building Energy Exchange, preaching the virtues of energy efficiency to New York City's real estate community, my first experience of a Passive House was indelible. Heading home from a walk in Prospect Park on an August evening, tired and hot, I somewhat begrudgingly agreed to stop by my wife's recently completed green roof project. It was a new installation and the young plants needed water to take hold and thrive. Leaving behind the leafy green of the park, we made our way through the steaming streets of Park Slope to the recently renovated brownstone, and its magical interior. It was summer in the city: hot, gritty, sweaty, noisy, smelly. We passed the ripe, pungent garbage, at the curb, the roar of the garbage truck, and the hot, loud blasts from window air conditioners, like small jet engines. A muggy afternoon, the car horns and exhaust hung in the air malevolently.

NYC 2030 District: A Living Lab Of Sustainability Efforts And Innovation

November 11, 2015

By: Shravya Jain

The verdict is in: 2015 is on track to be the warmest year on record. Fortunately, 2015 also promises to be the year when nations sign a climate agreement that will alter the course of history. Understanding that national ambitions to combat climate change need bottom-up support, the United Nations sponsored the Compact of Mayors — a global coalition of city leaders pledging to reduce their greenhouse gas emissions and head towards sustainability and New York City is one of those leaders. Consecutive mayors have made greenhouse gas emissions reduction as well as enhancing the resiliency of our built environment a priority. At present, the cities spew more than 51 million tons of greenhouse gases per year — a majority of which is building-related, so there is much to be done to meet Mayor de Blasio's goal of cutting our carbon emissions 80% by 2050.

Climate Scientists in the Crosshairs

September 01, 2015

By: Lauren Kurtz

The scientific method is based on the belief that research results should be subjected to the utmost scrutiny. But this principle can be turned on its head and scientists operating in politically controversial areas, particularly climate science, have been attacked by ideologically motivated groups trying any means possible to discredit, distract, and intimidate. Such tactics have included hate mail, death threats and even an anthrax scare. Less violently but no less noxiously, attacks via the legal system are an increasingly common way for self-styled "skeptics" to go after climate scientists with whom they disagree.
