Grow your buildings, shrink your carbon

Having an energy efficient building is only part of the equation towards building sustainability. The embodied carbon of your materials has a big impact on how green a building is. This week we are featuring a few stories on bio-materials (low carbon and renewable) as well as a couple of events promoting sustainable building.

The first event, September 11, is a talk by natural builder Chris Magwood, in Toronto on How Buildings Can (Help) Change the World. Then on September 30th you can visit bio-built homes with the Ontario Natural Homes Tour. On that same day Fourth Pig's Melinda Zytaruk is speaking in Bracebridge (Muskoka) Ontario about sustainable building and climate change. 

To start though, a new video about us just came out!

Senco produces short video on Fourth Pig

The Fourth Pig is featured in a short video by Senco - an initiative of Georgian College’s Centre for Changemaking and Social Innovation (CCSI). "Senco inspires, connects and equips those looking to engage in social enterprise to face cultural, environmental and social challenges in our region. We work with social enterprises, budding social entrepreneurs, organizations, intermediaries and community leaders to support innovative economic approaches to strengthen our communities. Our goal is to be the bridge to new knowledge, resources and supporting business practices to achieve financial growth and sustainability through social enterprise."

With Labour Day around the corner we are excited to be able to share a bit of what we do and why we do it in this short video.

Architectural Digest sees advantages of straw bale

Recently Architectural Digest had this clickbait worthy headline: "This Building Material May Hold the Key to Surviving Environmental Disasters". Spoiler: straw bales. Straw bales are a great building resource not only for the insulation value but as Architectural Digest says ". . .straw bales have proven themselves not only worthy fire adversaries, but also relatively stable during tornadoes and seismic shaking." Also worth noting is ". . .  straw bale was added to the 2015 International Residential Code (IRC) for one- and two-family dwellings, which allowed most Americans to build straw-bale homes. On January 1, 2017, straw bale became an appendix to the California Building Code."

Straw bale home 1st certified Passive House Plus

The Passive House Plus standard requires a significant amount of renewable energy use along with some energy production. In the town of Leyburn in the UK a straw bale building has met the challenge. Co-owner Ruth Barnet said in the Northern Echo "A lot of people thought it was strange, going down the green route. traders and suppliers would come on site, see the straw and the sheep’s wool and laugh and say ‘Where are the animals?'" The building is reportedly producing more energy than it needs and is of course comfortable. See photos here. 
 

Carleton U. to study occupant behavior in buildings

In the world of green building there is a lot of modeling that goes on predicting how people behave in buildings. What temperatures do people set? How much electricity in general is being used? What kind of heat is being generated by appliances, computers, peoples and pets? According to the Ottawa Business Journal Carleton University has received $350K from the federal government to study occupant behavior in buildings. "The project will study and model behaviour as occupants move throughout buildings in order to better predict how energy is consumed and find ways to reduce it. Carleton professor Liam O’Brien said in a statement that assumptions about occupancy can have a 'profound impact' on construction decisions." 
 

Using fungi to build buildings

We've reported before on folks who are growing fungi into building materials but now, according to the Guardian, things are, well, growing. London UK, the Guardian reports, is now "home to the Open Cell “bio-village”, a collection of 45 shipping containers being converted into pop-up biotechnology labs and workspaces." In this space there is research on vegan cosmetics, sustainable plastics and yes, fungi for building materials. The later is a company called Biohm. " One of the company’s most exciting new biomaterials is made of mycelia, the fine filaments of fungi that normally grow underground. The mycelia are harvested, fed on agricultural or food waste and grown in large sheets or blocks. Once the living element is killed, a fire-resistant structural material with excellent insulating properties is left."

These materials will reportedly be carbon neutral and high performing but this is early days. Also, Biohm is also working on panel construction system that doesn't require fasteners and could, in theory, allow for quite a change in building construction. See promo video below.

September 11 in Toronto: "How Buildings Can (Help) Save The World"

Don't miss it! September 11 in Toronto come hear Chis Magwood in a free talk: "How Buildings Can (Help) Save The World"

Climate change, indoor environment quality and ecosystem depletion are three major issues for the building industry and Chris Magwood has spent his career working toward practical, affordable solutions. Come and learn how the answers to these pressing concerns overlap nearly perfectly, solving any one of these issues conveniently creates solutions for all three.

Chris Magwood is currently the executive director of The Endeavour Centre, a not-for-profit sustainable building school in Peterborough, Ontario. He is co-editor of the Sustainable Building Essentials series from New Society Publishers, and is a past editor of The Last Straw Journal, an international quarterly of straw bale and natural building. 

This talk is part of Toronto Public Library's Civil Society series and part of the Fourth Pig's speaker series "Pig Tales".
 


Come out for Annual Ontario Natural Building Tour

Discover the beauty, comfort, and resilience of natural buildings across Ontario on Sunday September 30th. As it does each year the Ontario Natural Building Coalition hosts a tour of homes that went the natural way. "For the tour, dozens of natural homes and buildings across Ontario open their doors for participants to see examples of straw bale, rammed earth, cob, timber frame, off grid, passive solar, and many other natural building methods and alternative technologies."

This year it is a 2 for 1 for the Fourth Pig as we have two buildings next to each other that are participating in the tour. Come on out! Plus, if you are in the area, come see our own Melinda Zytaruk speak the same day (see below).

Education centre is Canada's first certified living building challenge building

In June the the Bill Fisch Forest Stewardship and Education Centre in Whitchurch-Stouffville, Ontario became the first certified Living Building Challenge building in Canada and one of only 21 in the world to achieve full certification. According to Construction Canada Amanda Sturgeon, CEO of the International Living Future Institute said “The Centre is a model example of humanity’s ability to reconcile our relationship with nature.”

Certification from the Living Building Challenge requires at least one year of data from occupancy demonstrating performance across a number of areas including including energy, water use and more. The goal is that Living Building Challenge buildings "give more than they take". 

The architectural firm DIALOG designed the building. Charles Marshall, sustainability associate at DIALOG, said in a piece in Canadian Architect that  “The biggest leap forward from standard practice that we can apply to any future project, and our greatest challenge, was pursuing the ‘red list’ requirement to eliminate chemicals of concern. We spent over three years researching and requesting ingredient lists and health product declarations from our suppliers in order to be compliant, and by the end of the project, wrote several hundred letters of advocacy asking for improved transparency.”

The building's other accolades and certifications are:

• Leadership in Energy and Environmental Design (LEED) Platinum certification
• Public Project of the Year – American Public Works Association
• Public Project of the Year – Ontario Public Works Association Canadian
• Green Building Award – Canada Green Building Council (CaGBC)
• Leadership Award – Forest Stewardship Council
• Environmental Building Award – Canadian Wood Council

See video below for a look at the building!

No screaming fans but these doors are tight

They may not light your fire but higher performance doors are making a difference. As Construction Canada observed "Regardless of location, air leakage and air exchange are two of the biggest issues facing architects, designers, and facility managers when it comes to specifying commercial rolling doors for conditioned warehouse spaces across the country."

New high performance doors, with better insulation, seals and opening/closing speeds, can have a real affect on the energy efficiency of buildings. Construction Canada reports that "Some rolling doors can decrease air infiltration by as much as 95 per cent, and manufacturers estimate savings of up to $1215 per door with a two-year return on investment (ROI) when selecting an energy efficient rolling door for the appropriate climate zone." Rock on

California met 2020 GHG targets in 2016
 

It's not news that most news on global warming is bad news. California though is offering up a bit of something to cheer; data released this month shows that the state hit its Greenhouse Gas Emission targets for 2020 in 2016. Environmental Defense shared that "This was the fourth year in a row of emissions reductions in California, where emissions dropped by 3% (12 MMt CO2e) between 2015 and 2016. Emissions fell 13% (64 MMt CO2e in 2016) compared against 2004, when emissions in the state peaked." Things look up a bit!

17 million data points a day test green reno

"Housezero" is a pre 1940's stick built home that Harvard University converted to the headquarters of the Centre for Green Building and Cities. Housezero, as Harvard Magazine reported, has "zero carbon emissions, zero electricity required from the grid, zero electric lighting needed during daylight hours, and zero fossil-fuel-driven heating and cooling."

It also is collecting 17 million data points a day run and test the building. "The data flow from two types of sensors. Some are critical to the operation of the building: for example, controlling the system of windows and shades in response to inputs about temperature, rain, wind direction, and indoor CO2 levels and air flows. Other sensors, purely observational, are intended to generate insights into optimizing the relationship between indoors and outdoors, while maximizing the health and comfort of the building’s occupants."

Notably, the original plan for the building included accounting for embodied carbon but as "many tons of concrete mass were added in the floors between stories during its renovation" the embodied carbon number is likely not very favourable. Still, it will be interesting to see what data and software comes out of the research. 

Canadian students compete in home building competition in China

29 students and professors from Concordia and McGill are building a net zero home as part of the Solar Decathlon competition in China according to CBC. The house is targeted to use 80% less energy than a typical home and to produce enough energy from solar panels to operate the home. The home is a modular design and is inspired by Montreal row houses and traditional Chinese siheyuan courtyard architecture. Listen to a CBC radio piece on the project right here

Toronto, don't miss "How Buildings Can (Help) Save The World"

Leading green builders encourage Ontario to improve building rebate program

FP GH logos.jpg

An effective green building program will help homeowners save money.

While disappointed that the Ontario government cancelled the newly minted GreenON rebate program, we urge the government to replace it with a reinstated Eco-Energy Audit program, an effective approach that will help homeowners reduce energy bills in addition to greenhouse gas emissions.

The GreenON program provided rebates for insulation, windows, geothermal, and air source heat pumps. While it offered homeowners an opportunity to offset capital costs to save money in the long-term, the program was limited in what it covered and required no third-party verification. Most concerning was the program’s support for high-carbon products rather than healthier, more low carbon and effective alternatives. Had GreenON continued, we would have strongly encouraged specific improvements.

The Ontario PC Party’s platform earmarked more than $500 million for environmental efforts. We encourage the new government to prioritize building retrofits. Buildings are the third largest contributor of greenhouse gas emissions in Ontario due to the energy used for heating and cooling and the embodied energy in building materials. Helping homeowners reduce their homes’ carbon footprint represents an opportunity to help them be part of the solution, while reducing their energy bills and contributing to local economies throughout the province. As the UN has stated: ‘Sustainable Buildings are the most cost effective solution to climate change’”.

By reinstating and modernizing the Eco-Energy Audit program, the province will offer homeowners cost and environmentally effective solutions to improve their home’s energy performance. Trained and certified energy auditors will provide third-party advice on “best-bang-for-your-buck” actions that homeowners share with their contractors to improve energy efficiency, home comfort and health. Work will be confirmed and tested by Energy Auditors to determine the rebate amount. Their oversight will ensure that energy retrofits are implemented effectively.

In addition to the Eco-Energy Audit program, we encourage the government to implement mandatory energy rating as a pre-sale requirement of homes. The Home Energy Rating and Disclosure (or HER&D) is a policy that is supported by the Ontario Home Builders Association among others. 

To reduce the embodied carbon in buildings, we ask the government to start a Life Cycle Assessment, which is a means of carbon accounting, as part of the building permit process.  

We have seen firsthand the effectiveness of Ontario’s former Eco-Energy program as a transparent, accountable and effective means to reduce a home’s carbon footprint and energy bills. We ask the government to reinstate it as soon as possible.

Rising to the challenge

Recently stories about the Living Building Challenge have been popping up, probably a good sign for one of the world's toughest building standards, and we have three Living Building Challenge stories here. We also have video on a Passive House affordable housing project (that we are proud to have worked on), an exciting event announcement and more. 

Thanks for reading!

Georgia Tech going down the Living Building Challenge path

The Kendeda Building for Sustainable Innovative Design at Georgia Tech is under construction and will be picking up some Living Building Challenge petals. Daniel Matisof, associate professor at the Georgia Institute of Technology, reported that Georgia Tech will be pursuing certification. "A new certification program inevitably involves increased challenges and costs associated with documentation and verification of performance. Significant investments in human knowledge and know-how need to occur in order to reach certification. By laying out a path to achieve Living Building certification, Georgia Tech can reduce costs for future adopters and increases the probability that other organizations undertake similar efforts," said Matisof. 

The aim is to be the first major Living Building Challenge 3.0 certified education and research facility in the American southeast. You can learn more and follow the progress of the building here. Also see this short video on the project:

Difficult marriage: project goes for Passive House and Living Building Challenge certifications

In the fall when the Fourth Pig was tabling at an event there were a few exhibitors with composting toilets and we asked them about how the venting worked with a Passive House and they weren't sure. Now, as Lloyd Alter reports in TreeHugger, the issue has come to, ahem, a head.

The Nuthatch Hollow building at Binghampton University is small but dreams big. As Alter says "They are trying to certify the building for both Passive House (PHIUS) and Living Building Challenge, and the two programs don't always play nice with each other. . . it is a little building, a lab and a multifunction room and some washrooms. But in the Living Building Challenge you can't have regular washrooms; you have to process all your waste on site, so many LBC buildings have composting toilets. These Clivus Multrum composters require lots of air to keep them from smelling, but Passive House buildings control the volume of air. So they have to put Heat Recovery Ventilators on the exhaust for the toilets and treat them as their own little separate world. (I asked why they couldn't run the toilet exhaust through the main HRV and was told that they were using ERVs or energy recovery ventilators, which can leak a bit.)"

There are also issues of materials that can and cannot be used in the Living Building Challenge and the challenge of getting what is needed for Passive House. Hats off to Ashley McGraw for the marriage of PH and LBC!

Winery tasting room awarded Living building Challenge

Last year we reported that the Cowhorn Vineyard and Garden in Oregon was built to the Living Building Challenge. Now it has received certification, making it one of twenty buildings in the world with that distinction according to a report in the DJC Oregon. “We’re the first tasting room in the world, and the first business to achieve it in Oregon,” Cowhorn owner Bill Steele said. “We’re the only small business in the world to have achieved the materials petal, which means everything, down to the last screw, was vetted.”

Latin America looking to bio-based building materials

According to Youris.com, Latin America is turning to bio-materials in buildings. Citing a recent study, Youris.com says "Brazil, Mexico, Colombia, Chile and Peru have carried out different measures ranging from relevant tax cuts to soft loans for sustainable construction." As readers know bio-based materials, such as straw bales, can sequester carbon and are highly sustainable. Projects in Latin America have ranged from straw bale to "super-adobe" earth bag buildings

Affordable Passive House buildings

One of the reasons we at the Fourth Pig are fans and practitioners of the Passive House approach is that it has great potential for affordable housing. With very low and very predictable energy bills, lower-income folks have a significant housing barrier removed. The Fourth Pig has acted as the envelope consultant for the Parkdale Landing project in Hamilton Ontario (plus we installed a bunch of windows). Check out this video on the whole project:

Image: Invizij Architects

In Hamilton Ontario the community agency Indwell continues to build affordable housing and now is working toward Passive House. The Fourth Pig is proud to be the air-tightness consultants (plus we will be doing some detailing) for the Parkdale Landing Project. The designers on these projects are Invizij Architects.

Getting to the full Passive House standard on a renovation is very difficult but following the  Passive House approach, you can get a very good building. Lloyd Alter at Treehugger reviews some of the numbers in his piece on these Hamilton projects.  

The CBC also ran a piece on how the Passive Standard is being used in affordable housing (including the Parkdale Landing Project).  At the Fourth Pig we have long advocated for all affordable housing buildings to be Passive House. Passive House not only reduces the hard to pay fluctuating heating and cooling bills by a huge percentage (often 70-90%) it provides comfort and reduces greenhouse gases. 

We are proud to be working on these exciting inititatives! 

 

 

 

Energiesprong and the push for energy efficient social housing retrofits

 Image: Source: http://energiesprong.eu/

Image: Source: http://energiesprong.eu/

This piece is taken from our newsletter "Force of Nature" see more and subscribe here.

Energiesprong ("energy leap") is an initiative launched in the Netherlands that is gaining interest around the globe. At the building level companies make prefabricated exterior wall and roof additions that can be put in place in about a week, essentially wrapping the house. The roof contains solar panels. In the Netherlands government support has been used to support the approach to social housing units with aims to have 100,000 units completed. To work economies of scale are important but homes are getting renovated right now. No word if they are using carbon sequestering materials. See videos below for more on how this works. 

The Pembina Institute recently wrote about the need to retrofit B.C's housing, particularly affordable housing and cited energiesprong as one possible model to draw on. Pembina will be launching an Affordable Housing Renewal Project which aims to "demonstrate that the challenges of aging, unhealthy buildings can be addressed with a solution that is affordable, fast, and scalable, while reducing carbon pollution and helping the province meet its climate commitments." 

The Energiesprong website lists France, the UK, Germany and New York State as other locations where initiatives are happening. However, this month the Rocky Mountain Institute was awarded funds for "Experimental Envelope Fabrication Process for Integrated Zero Energy Ready Multifamily Renovations." 

PHIUS and the Net Zero Energy Coalition (NZEC) are partners in this project. PHIUS reports that "This grant allows RMI, PHIUS and NZEC to develop high performance building envelope assemblies for new and retrofit buildings. PHIUS will take the lead in developing retrofit standards and industry guidance for single family and multifamily homes, and will oversee monitoring, measurement, and quality assurance for prototypes and pilot projects"  Katrin Klingenberg, Director of PHIUS, said "Tailoring envelope assemblies to climate zones is critical to making high performance buildings affordable and effective. “It is the most cost effective route to zero. We are excited to help in creating standards and design guidelines that make zero energy buildings possible everywhere.”

Wrapping buildings isn't a new idea, in fact we wrote about it in this newsletter awhile back. What is different here is the attempt to do it on a large scale, with full wall and roof systems, quickly so that residents can remain on site and with a focus on social housing. We will hear more about this approach in the months and years to come.  

The first video below explains the basic idea of Energiesprong and the second is a video of a one day Energiesprong retrofit:

Fourth Pig Celebrates 10th Birthday!

birthday-cake-logo.jpg


Happy Birthday to us! Ten years ago Melinda Zytaruk, Sally Miller, Glen Byrom and Matthew Adams decided to launch a different kind of organization that would build buildings differently. Ten years ago we launched the Fourth Pig. Ten Years ago, on May 31st 2007, we were officially incorporated. 
 
One of our main concerns was and is the impact that buildings have on climate change. When it comes to affecting climate change changing the way we build is super low-hanging fruit. The United Nations reports that buildings account for 30% of Greenhouse Gas Emissions. If you want to affect climate change you have to change the way buildings are built.

We were and also remain committed to the use of non-toxic healthy materials. People spend a lot of time in buildings and what is in them matters to the health of the occupants. Out of these perspectives came our mission:  to foster ecologically balanced methods of construction and energy production in order to promote more sustainable and healthy communities.
 
To begin we incorporated as a worker cooperative. Worker co-ops are owned and operated by its members and as we promoted a different, more sustainable way of building, we wanted our organization to reflect a more sustainable model- one where workers not only a voice, but real control and shared responsibility for the organization. We also made the company a non-profit, with a commitment to providing public education around sustainability and resilience. 
 
Ten years later we are still at it. 
 
The organization has grown with amazing new members and we have a completed a number of interesting projects. We continue to be committed to energy efficient, low-carbon buildings and are active in promoting green building through talks, trainings, articles, open-houses, and social media. Of course we are walking the talk by building and renovating in a way that promotes the health of the building occupants and the health of the planet. 
 
Thank you to everyone in the green building and co-op communities for supporting our work over the last decade. We look forward to the next amazing ten years!
