Net Zero Energy Buildings at the Poles

The NYTimes published "The Coolest Architecture on Earth Is in Antarctica" by John Gendall on January 6, 2020. (https://www.nytimes.com/2020/01/06/science/antarctica-architecture.html)
It was a general overview of new research stations and their designs to cope with the "world’s harshest environment."

According to the story, designer architects are bringing "aesthetics — as well as operational efficiency, durability and energy improvements” to the new buildings planned or under construction.

The Halley VI research station of the British Antarctic Survey, designed by Hugh Broughton Architects, is credited with changing the state of the art.  The Halley VI is built on hydraulic stilts, "allowing operators to lift it up out of accumulating snow drifts. And if the entire station needs to be moved — it sits on a drifting ice shelf — skis at the base of those stilts make that possible."

India’s National Center for Antarctic and Ocean Research’s new research station, is built, partially, out of the shipping containers the rest of the materials came in, designed into the process from the beginning by the German architecture firm of bof architekten.

The article quotes Ben Roth of the Antarctic Infrastructure Modernization for Science, or AIMS, the National Science Foundation initiative to modernize the USA’s McMurdo Station, as saying the existing buildings there are “energy hogs” which create additional problems for scientific research.

It was a good article but, since I’ve been collecting links to developments in net zero energy buildings since 2013 (http://solarray.blogspot.com), I was surprised that the world’s first zero emission polar research station with a decade’s worth of operating experience, the Princess Elisabeth Station in Antarctica (http://www.antarcticstation.org), the research station of the International Polar Foundation based in Brussels, was not mentioned at all.  I’d like to know if the Princess Elisabeth Station is still the only zero emission polar research station and if so, why;  but both the station and the concept of net zero energy seems to absent from the architectural context of this particular article in the NYTimes.  

The fact of the matter is there are net zero buildings at every scale, at every price in every existing climate, including net positive energy buildings in polar regions.

Snøhetta is the company to watch as they have completed the world’s northernmost energy-positive building, an 8-story, 18,000 square meter Powerhouse Brattørkaia in Trondheim, Norway "which produces, on average, more than twice as much electricity as it consumes daily”
(https://snohetta.com/projects/456-powerhouse-brattorkaia-the-worlds-northernmost-energy-positive-building
https://inhabitat.com/snohetta-completes-worlds-northernmost-energy-positive-building/)
and another far Northern net positive energy office building
(http://snohetta.com/projects/283-powerhouse-telemark
http://inhabitat.com/worlds-northernmost-plus-energy-office-could-spark-an-energy-revolution/)
They also worked on Harvard’s HouseZero, a near net zero retrofit of a 1940s building in Cambridge, MA.
(http://harvardcgbc.org/research/housezero/)

In addition, California’s Title 24-2019 is the first state code in the USA in force now to require solar panels and nearly net zero levels of energy consumption in all new homes through improvements in the building’s thermal envelope and demand responsive technologies including battery storage and heat pump water heaters 
(https://ww2.energy.ca.gov/title24/2019standards/documents/2018_Title_24_2019_Building_Standards_FAQ.pdf https://www.energy.ca.gov/programs-and-topics/programs/building-energy-efficiency-standards/2019-building-energy-efficiency
https://zeroenergyproject.org/2019/02/18/2019-is-the-year-of-energy-codes/)

The EU has near net zero building standards as well through their Energy Performance of Buildings Directive or EPBD which "requires all new buildings from 2021 (public buildings from 2019) to be nearly zero-energy buildings (NZEB)” meaning "a building that has a very high energy performance... The nearly zero or very low amount of energy required should be covered to a very significant extent from renewable sources, including sources produced on-site or nearby."
(https://ec.europa.eu/energy/en/content/nzeb-24)

We have built net zero energy buildings in every climate on Earth.  Over the next few decades we will rebuild our structures to those standards and, eventually, replace the energy from the grid that goes into our buildings, about a third of all energy the USA generates in a year, about 33 quadrillion btu’s with energy efficiency and energy production onsite.

This is the reality coming down the pike.  The more we recognize it, the faster it will happen.  Changing building codes across the USA is a significant leverage point for reducing greenhouse gas emissions, energy waste, improving resilience and preparedness (Solar IS Civil Defense), and building a renewable future now as Justin Gillis has recognized, also in the NYTimes
(https://www.nytimes.com/2019/03/20/opinion/climate-building-codes.html).

What I Read in the Green New Deal for Public Housing Bill

The Green New Deal for Public Housing Act (these comments come from the draft https://ocasio-cortez.house.gov/sites/ocasio-cortez.house.gov/files/OCASNY_053_xml.pdf but the actual bill has now been filed at https://www.congress.gov/bill/116th-congress/house-bill/5185/text) is the first binding legislation drafted.  It will reconstruct "the entire public housing stock of the United States, as swiftly and seamlessly as possible,” into zero-carbon homes, "a highly energy-efficient home that produces on-site, or procures, enough carbon-free renewable energy to meet the total annual energy consumption of the home” within a decade.

Public housing stock will be eligible for deep energy retrofits, including 
energy-efficient windows; 
super insulation of roofs and exterior walls, including the addition of new cladding to buildings and the rerouting of plumbing and electricity; 
electrification of water heating and building heating systems using electric heat pumps; 
and electric heat pumps to provide air conditioning, where feasible; 
materials and technology to increase airtightness of the building envelope, including air sealant paints; the acquisition and installation of heat-recovery ventilation systems; 
and energy monitoring devices including smart meters and smart thermostats.  

There will be grants "to build and expand community energy generation in public housing, including 
the construction of and ongoing costs associated with renewable energy rooftops; 
renewable energy generation; 
photovoltaic glass windows; 
the bulk purchase of clean energy supply from energy utilities; 
and community-scale energy storage."

What the bill is calling a zero carbon home is also known as zero net energy housing or, more commonly, net zero energy buildings, structures which produce as much energy as they consume and such buildings have been built in just about every Earthly climate, from the Arctic Circle to the South Pole;  at single family and skyscraper scales;  at low, moderate, and luxury prices.  I’ve been collecting examples of Zero Net Energy buildings and technologies for years at http://solarray.blogspot.com if you want to see what is operating now, is being built, and some of the design visions for the future.  CA is already transitioning to a net zero energy building standard for all low-rise residential buildings now (2020) and the EU is moving to a “near net zero” standard now too.  Both will have a net or near net zero building standard for all buildings, including rehab, by 2030.

There are positive net energy buildings as well (see http://solarray.blogspot.com).

In 1979 Jimmy Carter’s energy plan called for insulating 90% of American homes and all new buildings and use solar energy in more than 2.5 million homes by 1985. There were 1.3 million solar installations in the USA in 2017 by one count and may be 1.9 million in 2019 by another.  The DOE is predicting there will be 3.8 million solar homes by 2020.

Carter also wanted "20% of our energy coming from solar power by the year 2000."  Renewables, wind, solar and hydro, are at just about that level now, 20 years behind his schedule.

Carter was thinking in terms of his next four years in office. Extinction Rebellion is demanding that “Government must act now to halt biodiversity loss and reduce greenhouse gas emissions to net zero by 2025.”  The Green New Deal has a 10 year timeframe.

Jimmy Carter in 1979 was more ambitious than we are now. 

The Green New Deal for Public Housing also provides for community resilience centers, "a communal space in public housing that is used as a cooling center, heating center, or disaster relief center during extreme weather.”  This fits in with the idea of emergency preparedness, civil defense, no matter what the opinion of climate change.  After all, Solar IS Civil Defense (and entry level electricity for the billion or so people in this world who don’t yet have access to minimal electricity for light, communications, and other things.  See Personal Power Production:  Solar from Civil Defense to Swadeshi (http://solarray.blogspot.com/2010/12/personal-power-production-solar-from.html) for more on these concepts and Personal Power Set (http://solarray.blogspot.com/2018/09/personal-power-set.html) for a look at current available technologies.

Community resilience measures include a "grant program to help provide the purchase and installation of energy storage, including batteries, flywheels, compressed air, and pumped hydroelectric or thermal energy storage, in order to ensure energy backup of not less than 48 hours in the event of an emergency or disaster;  the construction of childcare centers and ongoing costs associated with childcare centers;  the construction of senior centers and ongoing costs associated with senior centers;  the construction of community gardens and ongoing costs associated with community gardens.”

This will allow public housing to become islanding microgrids, housing that can power themselves when the grid goes down.  Grid interconnection will also allow public housing to feed energy back into the grid and offset costs.

The Green New Deal for Public Housing Act also authorizes the "training and development of skills necessary for career development in the fields, trades, and services reasonably determined during the first public comment period held in accordance with subsection (b)(3) to be of interest to public housing residents,” at a wage of $15  per hour with "stipends valued at not less than $250 per week to individuals participating in the workforce development program.”

Using the reconstruction of the USA's public housing as a job development program in energy efficiency and renewable power is supported by the results of the 2019 US Energy and Employment Report [USEER]* which found that there are currently more clean energy jobs available than workers to fill them.  The lack of trained people was highlighted by virtually all surveyed sectors as a growing problem with lack of experience, training, and technical skills almost universally cited as the top reason for hiring difficulty by employers. The need for technical training and certifications was also frequently cited, implying the need for expanded investments in workforce training and closer coordination between employers and the workforce training system.

US Energy and Employment Report [USEER]*  also found that energy efficiency has the most overall growth and potential for jobs.  It is about 41% of energy sector jobs now.  More than 1 out of 6, 17% of all USA construction jobs are in energy efficiency.  E2 [Environmental Entrepreneurs] (https://www.e2.org) has an Energy Efficiency Jobs in America report that goes deeper into this subject (https://www.e2.org/reports/energy-efficiency-jobs-in-america-2019/).  Cities like Boston have found that energy efficiency retrofits, electrification of existing residential buildings, and improved transportation are the most impactful strategies for reducing carbon emissions (http://sites.bu.edu/cfb/files/2019/01/Carbon-Free-Boston-Report-web.pdf).

The Green New Deal for Public Housing Act requires biannual reports
"on the impact that the grant programs established under subsection (a) have had on—
(1) the rehabilitation, upgrades, innovation, and transition of public housing in the United States;
(2) total greenhouse gas emission output, and quarterly data on greenhouse gas emission reductions from individual public housing developments, specifically as they relate to—
(A) home energy carbon pollution emissions in each public housing development, as calculated using the Carbon Footprint Calculator from the Environmental Protection Agency;
(B) waste-related carbon emissions in each public housing development, as calculated using the Carbon Footprint Calculator from the Environmental Protection Agency; and
(C) total greenhouse gas emissions released by individual public housing buildings and homes within a public housing development, as calculated using the Greenhouse Gas Equivalencies Calculator from the Environmental Protection Agency;
(3) the amount of Federal money saved due to energy cost savings at public housing projects, on a quarterly basis;
(4) the amount of energy savings per KwH at each public housing project, on a quarterly basis;
(5) public housing residents, including—
(A) access to economic opportunities through compliance with the hiring and contracting requirements described in subsections (c) and (d) of section 3 of the Housing and Urban Development Act of 1968 (12 U.S.C. 1701u);
(B) the impacts, if any, those residents have experienced to their individual economic growth as measured by individual and household income;
(C) the specific career skills acquired;
(D) the impacts, if any, those residents have experienced to their overall health; and
(E) the specific educational or technical certifications acquired; and
(6) changes to the overall community health indicators in public housing developments and their surrounding neighborhoods, including asthma rates, air quality, water quality, and levels of lead and mold.”

And
"Before the start of the second fiscal year beginning after the date of enactment of the Green New Deal for Public Housing Act, and quarterly thereafter, the Secretary shall require each public housing agency to monitor, measure, and report to the Secretary on the economic impacts of this section on the community in which housing developments of the public housing agency are located, including

‘‘(A) the aggregate dollar amount of contracts awarded in compliance with this section; 
(B) the aggregate dollar amount of wages and salaries paid for positions employed by low- and very low-income persons in accordance with this section;
(C) the aggregate dollar amount expended for training opportunities provided to low- and very low-income persons in accordance with this section; and
(D) the aggregate dollar amount expended for training and assisting public housing resident-owned businesses for compliance with this section."
The Green New Deal for Public Housing Act guarantees "the right to housing for every individual… all housing in the United States is habitable, highly energy-efficient, and safe; and… that the Federal Government should act and build new public housing where there is a serious need that the free market cannot address or is not addressing responsibly.’’

Most, if not all. of the Green New Deal for Public Housing necessitates "SEC. 10. REPEAL OF FAIRCLOTH AMENDMENT. Section 9(g) of the United States Housing Act of 1937 (42 U.S.C. 1437g(g)) is amended by striking paragraph (3), Faircloth Amendment which forbids HUD to "fund the construction or operation of new public housing units with Capital or Operating Funds if the construction of those units would result in a net increase in the number of units the PHA owned, assisted or operated as of October 1, 1999."

What To Do After the Climate Strike

Fridays for the Future (https://www.fridaysforfuture.org) - the Friday Climate Strikes continue
October 2 there will be a Global Solar Yatra (https://www.ggsy.in) with 1 million students in over 70 countries building their own solar lights for studying
October 7 Extinction Rebellion (https://xrmass.org/action/nyc-kickoff-global-rebellion/) will be doing actions around the world
Sunrise Movement (https://www.sunrisemovement.org) is planning actions in support of the Green New Deal up to and after the Inauguration of the next President in January 2020

September 20 was a great show of strength but what are we going to do tomorrow and the day after that?  Is there a daily climate practice that can do what we need to get done in the time available?  I know someone who used to write a letter to the editor to some publication around the world on climate issues every day.  Now he does stand outs most mornings during rush hour traffic with his climate signs.  Another is standing up in the train to talk about climate on the commute home.  (“How did Solidarity start?” someone once asked Lech Walesa who answered, “By speaking loud at the bus stops.”)  I have a solar swadeshi myself: http://solarray.blogspot.com/2005/05/solar-swadeshi-hand-made-electricity.html
and have been practicing Solar IS Civil Defense for 20 years:
https://www.dailykos.com/stories/2017/9/8/1697177/-Is-It-Time-to-Talk-About-Solar-Civil-Defense
https://www.dailykos.com/stories/2007/3/30/317777/-

If the children can devote one day a week to climate issues, the adults should too.  Climate strikes can evolve into climate teach-ins, brainstorms, hackathons, and barnraisings, especially if we have a daily climate action plan on international, national, regional, state, county, municipal, neighborhood, family, and individual scales with benchmarks and targets.

Greta Thunberg at the UN mentioned that we are on track to burn through our carbon budget, the amount of greenouse gases we can put into the sky and still stay within that “magic” 1.5º F heating range, within 8 years.  That’s one benchmark.  The idea that “we have a little more than a decade” to turn around climate comes from a 2017 paper from Christiana Figueres, Hans Joachim Schellnhuber, Gail Whiteman, Johan Rockström, Anthony Hobley & Stefan Rahmstorf.  What gets mentioned less is their six-point plan with specific targets for turning the tide of the world’s carbon dioxide by 2020:  https://www.nature.com/news/three-years-to-safeguard-our-climate-1.22201

However, China may reach its greenhouse gas emissions peak in 2022, far ahead of its 2030 schedule announced at the 2015 Paris climate meeting:
https://www.reuters.com/article/us-china-carbon/china-co2-emissions-to-peak-in-2022-ahead-of-schedule-government-researcher-idUSKCN1VQ1K0
and Norway, Iceland, Costa Rica, Nicaragua, Uruguay, Paraguay are all countries which get almost all their electricity from renewable energy now:  https://www.climatecouncil.org.au/11-countries-leading-the-charge-on-renewable-energy/
Costa Rica plans to be a carbon neutral nation by 2021:
https://www.nytimes.com/2018/09/21/climate/costa-rica-zero-carbon-neutral.html

Job One for Humanity (https://www.joboneforhumanity.org/plan) has a four point plan for climate action starting from emergency preparation and working on up to mass political and social change.  Many of their ideas are not only adaptation to the weather emergencies they believe are now inevitable but also best practices which will also mitigate any more climate damage and improve individual, family, and local resilience.

Lots to do and lots we can do.

Agrophotovoltaics, Agriphotovoltaics, Solar Sharing

Fraunhofer Institute in Germany has been doing “agrophotovoltaics” studies for the last few years, the concept of producing both crops and solar power on the same land.  Their 2018 study results are available here: https://www.ise.fraunhofer.de/en/press-media/press-releases/2019/agrophotovoltaics-hight-harvesting-yield-in-hot-summer-of-2018.html

”The results from 2017 showed a land use efficiency of 160 percent, as confirmed by the project consortium under the direction of the Fraunhofer Institute for Solar Energy Systems ISE. The performance of the agrophotovoltaic system in the very hot summer of 2018 greatly exceeded this value.”

Fraunhofer is also doing tests of solar panels over shrimp ponds in Vietnam:
https://www.ise.fraunhofer.de/en/press-media/news/2019/aqua-pv-project-shrimps-combines-aquaculture-and-photovoltaics.html
They show similar results there, too, possibly even better as the solar shading is more conducive to shrimp growth.  If there are any applicable aquaculture facilities in your state, there might be some solar opportunities available there too.

What Fraunhofer calls agrophotovoltaics the Japanese call  “solar sharing” and have been doing since at least 2004:
https://www.renewableenergyworld.com/2013/10/10/japan-next-generation-farmers-cultivate-agriculture-and-solar-energy/

”The concept was originally developed by Akira Nagashima in 2004, who was a retired agricultural machinery engineer who later studied biology and learned the “light saturation point.” The rate of photosynthesis increases as the irradiance level is increased; however at one point, any further increase in the amount of light that strikes the plant does not cause any increase to the rate of photosynthesis….

”Based on the tests conducted at his solar testing sites in Chiba Prefecture, he recommends about 32% shading rate for a farmland space to reach adequate growth of crops. In other words, there is twice as much empty space for each PV module installed.”

UMass Amherst is working on this concept as well with outreach to farmers through a state program:
https://ag.umass.edu/clean-energy/fact-sheets/dual-use-agriculture-solar-photovoltaics

Mother Jones article on this idea:
https://www.motherjones.com/food/2019/09/the-best-place-for-harvesting-solar-energy-is-not-where-i-expected-it-to-be/
Paper from Nature Sustainability the article references
https://www.nature.com/articles/s41893-019-0364-5.epdf

There should be no competition between active farmland and solar development.  When done correctly, solar can become a lucrative second “crop” for farmers while maintaining and, in some cases, increasing agricultural productivity.

Old Solar: Jimmy Carter's 1979 Green Deal

Jimmy Carter’s energy plan called for "20% of our energy coming from solar power by the year 2000" in 1979. Renewables, wind, solar and hydro, are at just about that level now, 20 years behind his schedule.


Carter also wanted to insulate 90% of American homes and all new buildings and use solar energy in more than 2.5 million homes by 1985. There were 1.3 million solar installations in the USA in 2017 by one count and may be 1.9 million now by another and all low-rise residential buildings in CA will be built to net zero energy standards starting in 2020.


Carter was thinking in terms of his next four years in office. Extinction Rebellion is demanding that “Government must act now to halt biodiversity loss and reduce greenhouse gas emissions to net zero by 2025.” The Green New Deal has a 10 year timeframe.


The argument can be made that Jimmy Carter in his cardigan sweater spouting “mush from the wimp” is more radical about energy than almost anyone in the public eye today.


PS: Reagan won the 1980 election and shut down the building solar wave with extreme prejudice. Reagan killed us. Carter’s energy plan would have saved us (as long as the terrible shale oil component was shelved).
