A team of researchers from U of T Engineering is partnering with the construction industry to help reduce the carbon footprint of buildings, bridges, public transit and other major infrastructure projects.

“What we’re building is a decision-support tool that can be used in the early stages of design and planning,” says Professor Heather MacLean (CivE), one of five U of T Engineering professors involved in the project. “Ultimately, the goal is to produce infrastructure with much lower greenhouse gas impact.”

While green building certification programs have existed for decades, MacLean and her collaborators — including Professors Brenda McCabeDaman PanesarDaniel Posen and Shoshanna Saxe (all CivE) — point out that these are typically considered only toward the end of the design process, when most major decisions have already been made.

“The decisions that have the most impact are the ones that are made early in the process,” says Saxe, who specializes in analysis of transit infrastructure. “These include how big it’s going to be, or what materials it will be made of. Once those are set, it really puts limits on how low the overall emissions can get.”

Nearly a year ago, the team was approached by EllisDon, a major construction and building services company headquartered in Mississauga, Ont. As part of its Carbon Impact Initiative, the company and its partners, including BASF and WSP, are collaborating on projects that aim to elevate efficiency and sustainability in the built environment.

In their early talks, the researchers and industry partners quickly identified science-based decision support in the early stages of project planning as a key strategy for emissions reduction. They plan to analyze data from previously constructed projects and publicly available databases to generate predictive tools.

“Large-scale infrastructure projects are complex, consisting of many different construction activities, along with associated inputs of material and energy,” says MacLean. “We don’t yet have good data about the on-site and supply-chain emissions associated with these inputs, especially those specific to the Ontario context. If we can cut down on that uncertainty, it will greatly help inform these types of decisions.”

Today, the Ministry of Research, Innovation and Science announced that the project was among those that received funding through the TargetGHG program, administered by Ontario Centres of Excellence, which supports industry-academic collaborations that will help the province meet more aggressive future GHG targets.

“Supporting the efforts of large industries in their quest to reduce their greenhouse gas emissions is an important part of our government’s Climate Change Action Plan,” says Reza Moridi, Minister of Research, Innovation and Science. “With the help of our province’s innovative cleantech companies, the TargetGHG program will help build a prosperous, low carbon economy and create a cleaner, more sustainable future for Ontario.”

In total, the project has attracted more than $2 million in funding from a variety of sources, including the Natural Sciences and Engineering Research Council of Canada (NSERC) as well as financial and in-kind contributions from the industrial partners.

“Taking steps to reduce the impacts of greenhouse gases and air pollution on our climate and environment is a key priority in Canada,” says Dr. Marc Fortin, Vice-President, Research Partnerships, Natural Sciences and Engineering Research Council of Canada. “NSERC is proud to partner with Ontario Centres of Excellence to connect Canada’s top researchers and companies to develop innovative clean technologies that will advance environmental sustainability in Canada and improve the health and quality of life of Canadians.”

“This project is a wonderful example of how our researchers leverage strong collaborations with industry to develop next-generation solutions to society’s most pressing challenges, including climate change,” said Ramin Farnood, Vice-Dean, Research at U of T Engineering. “This tool has great potential to enhance the sustainability of major infrastructure not just here in Ontario, but around the world.”

A second U of T Engineering project, focused on installation and testing of fast-charging stations for electric vehicles, also received funding through the TargetGHG program. Led by Professor Reza Iravani (ECE), it will be carried out in collaboration with energy storage company eCAMION.

MacLean and her team are already looking to recruit the graduate students and postdoctoral fellows who will collect and analyze the data, and continue to work closely with their industrial partners as they move forward.

“It’s exciting to be working with partners that are eager to roll out solutions,” says Posen. “We have had great meetings, and we have a strong sense they are looking to turn this research into practical results.”

Systems, surroundings, crosstalk, and critical mass: Prospects for improving indoor solid-fuel burning

Abstract: 

Three billion people burn solid fuel to cook and heat. Four million people die prematurely because of exposure to particulate matter emissions from this burning every year. These impressive statistics have garnered donor attention, motivated design of combustion devices, and prompted intervention programs large and small.

The simple nature of the “three-stone fire” and the relative poverty of its users initially fooled engineers and implementers into believing a massive transformation was near at hand. Why does a major public health problem still exist, if the solutions are basic? On the technical side, burning a complex fuel without initial distillation is an extremely difficult problem. More importantly, the humble cookstove is embedded in a web of systems: technology support, household interactions, user limitations and ambitions, physical resources, and expectations from the international community. Meeting the challenge of providing clean energy for all will require engineers to be both technical experts and systems thinkers.

Tami Bond is a professor of Environmental Engineering at the University of Illinois. Her research has followed a thread from combustion, to atmospheric chemistry and climate, to technology change and future scenarios, to the intimate relationship between technology and human choice. Beginning in an auto repair garage and detouring through indoor air and building energy, Bond first earned two degrees in mechanical engineering, before succumbing to an interdisciplinary Ph.D., pursuing a NOAA Climate and Global Change post-doc, and eventually landing in a civil engineering department. Her research group now spans considerations as small as a particle’s skin and as large as a national transportation system in the quest to characterize the dance between humans, “their stuff,” and the atmosphere and climate.

Rural energy sources, like cookstoves, have been a common theme in Bond’s work since her post-doctoral days, when people would mail her lumps of coal to aid in the search for missing sources. Members of the Bond group have chased smoke on four continents, participated in international standards and testing initiatives, and worked with non-governmental organizations to bring testing capabilities closer to implementers.

The S-WORD: Defining Sustainability

#Sustainability?

Today, people argue, the power of the word ‘sustainability’ has been diluted due to overuse. What began as a noble ideal has been reduced to a mere buzzword. We sat down with some of our professors to understand how ‘sustainability’ is more than hype for them and their research.

 

Professor I. Daniel Posen
Research Focus: Providing system-scale environmental sustainability analysis for policy development

Large-scale systems are inherently complex. When holistically evaluating the ‘sustainability’ of a system a broad range of environmental, societal and economic metrics compound the matter. Naturally, a professor with such a research focus has a complicated relationship with the word ‘sustainability’. Riddled with over-hyped products, under-delivering theories and overall ‘greenwashing’, Professor Posen believes the discourse is weak.  He particularly notices the current lack of numerical definition.

Posen’s research exists at the intersection of engineering, environmental science, economics and public policy. His cross-discipline approach engenders a complete evaluation of all ‘sustainability’ efforts. It is with this integrated analysis that Professor Posen seeks to inform future system designs yielding greener outcomes.

Success in his quantitative analysis for policy development depends on capturing all factors, inputs and circumstances. The accuracy and availability of data, the consistency of modelling efforts across fields and the incorporation of nascent technologies are some challenges he must address. The variables are numerous, nuanced and involve advanced statistical analysis. Iterations are necessary to provide confidence ranges and uncertainty measurements to help craft policies.

Appropriately, Posen views ‘sustainability’ through a system-wide lens, considering the triple-bottom line inclusive of social, ecological and financial effects. He believes to operationalize ‘sustainability’ it must be reduced to measurable properties. Developing empirical tools to assess current levels, magnitude changes and confidence levels are all integral points in sustainability’s definition. Once these methodologies are in place, it is important to tell the data’s story accurately and without bias mobilizing policy makers driving real change.

With recent developments of the pan-Canadian climate framework addressing the country’s 2030 emissions reduction targets, Posen’s research plays an essential tool for government. Most recently, in conjunction with Professor Heather MacLean and a charitable environmental organization called Pollution Probe, Professor Posen is working on a white paper providing analysis to the Government of Ontario. The paper will provide guidance in provincial emissions from indirect land use change and carbon accounting for biofuels as part of both Ontario Renewable Fuel Standard and Canada’s Clean Fuel Standard.

“It is necessary to remember that though governments can shift and mandate new targets, magnitudes of change in one area will have consequences in another,” Posen says. These market-rebound and indirect effects are an important consideration in Professor Posen’s research.

“It is not as simple as implementing biofuels to reduce green house gases (GHG),” says Posen. According to the professor when addressing GHG mitigation strategies, policy makers need to consider the totality of costs and benefits associated with the proposed protocols. If a food production crop is replaced with a bio-fuel-bound crop, this change will have implications not only in the energy sector but also for world hunger and food scarcity problems. Once bio-fuel crops are harvested, refining the biomass consumes energy, processing will affect air quality and the infrastructure needed to support distribution efforts requires investment. These are only a sampling of considerations to address when evaluating and selecting among the competing uses for biomass and prioritizing GHG mitigation strategies.

Other examples of sustainability analysis issues include prioritizing certain sectors before others, market price fluctuations and accounting for technologies that currently do not exist. New developments create alternative scenarios. Policy makers forge new directions with each new regulation. Some directions will lead to fruitful and tangible results while others will lead to dead ends. Confounding the issue, attributing the origins of outcomes is difficult to disentangle empirically. Posen is working to identify new, precise measurement modelling to improve path forecasting.

Professor Posen’s previous work focused on large-scale systems at global and national levels. He is currently looking to address city-scale systems. As global leaders discuss and stipulate new green targets and frameworks, cities have an important role in implementing and driving their success.

“Often cities do not have an accurate picture of their current emission levels, for example. It proves difficult to identify necessary fundamental policy changes without data to inform the direction,” says Posen. “With increased capacity to collect, analyze and disseminate crucial data points, local officials can make substantial changes that benefit both the short and long run sustainability of cities.”

Professor Tamer El-Diraby
RESEARCH FOCUS: Construction management for societal and corporate changes

Professor El-Diraby agrees the conversation around ‘sustainability’ needs to be more than a passing fad. He notes, buzzword or not, ‘sustainability’ promotes positive results. “It is just a given nowadays,” he remarks. “Most governments, businesses and our society as a whole accept and are prioritizing its implications.”

El-Diraby notes his school-age children studying sciences are now learning through a lens of ‘sustainability’. The generational expectation for sustainable efforts is non-negotiable. Despite its hashtag status, he believes there is a general movement from generic thoughts to actionable policies and programs for energy conservation and climate change. “While we may be bored with its use, caring about these issues is the result of profound belief in ‘sustainability’,” says El-Diraby. The Professor warns that not all who use the term have noble intentions. Some companies are abusing the term and diluting its operational power.

In construction management, Professor El-Diraby focuses on more than just green technology and number crunching. He is interested in the business case, change management and the sociology of embracing ‘sustainability’. The professor is using social network analysis to help discover how communities – both citizens and professionals – view ‘sustainability’. Through crowdsourcing, the Professor is sifting through the noise uncovering interesting insights.

A large portion of his research examines how to manage and support implementation efforts for ‘sustainability’. Leveraging data analytics to help managers discover new knowledge or patterns of change, El-Diraby develops tools to help coordinate decision-making.

Across the global construction industry, many of the environmental and economic challenges with infrastructure systems are the same. However, the social aspects of ‘sustainability’ vary with the developmental phase of the city and country.

In Canada, with pre-existing infrastructure, governing bodies are seeking to change long-standing unsustainable construction practices. In a country like China, which is building new infrastructure, there is an opportunity to incorporate green construction and promote sustainable habits from the beginning. China is seeking to develop while Canada is seeking to optimize its developed systems. The methods are distinct but overall the goals remain the same.

Potential game changers are close, Professor El-Diraby believes for the construction management industry. He is confident the future is poised for many new impacts, which will improve the health and livability of our cities.

Automation | 3D printing and robotics are increasingly used. These technologies provide significant productivity improvements and elevate our capacity to examine complex problems.

Digitization | New technology called Building Information Modeling (BIM) is allowing sophisticated analysis and enhanced cross-border collaboration. The supply chain for construction design, finance and production is globalizing and yielding great benefits.

Net-generation | New construction customers are perceptive. They are acutely aware of sustainable energy options. These new players will force the industry to surpass green regulations and adapt to serve consumer demands.

Modern cities | There is a need for installing and re-configuring our infrastructure to accommodate new urban technologies such as driverless cars.

Professor Evan Bentz
RESEARCH FOCUS: Concrete and structures standing the test of time

“Sustainability is indeed a word that has become less powerful due to repeated use, but still represents an important concept,” says Professor Bentz. Speaking as a concrete expert, the term evokes similar feelings to “resilience” – which the Professor notes is also pervasive in the industry.  In both cases, Bentz believes these terms are important considerations and afford design engineers a point of reference when talking with building owners.

Bentz laughs when he recalls the reception the term artificial intelligence received during the 1980’s. Back then, engineers believed AI was probably impossible and discredited the term quickly. Fast forward to 2017 and AI is now a worthy pursuit many corporate giants are chasing. His bit of trivia elucidates; trending or not, engineers must address ‘sustainability’ today and ready themselves for the unexpected of tomorrow.

When studying concrete, Bentz uses ‘sustainability’ to imply longevity and practicality. “As engineers we need to build lasting structures and, given the constraints of the project, use materials as efficiently as possible,” says the Professor.  “In a sense, it is an attempt to provide an accounting of environmental issues previously neglected by our profession.” Improving building codes and creating increasingly efficient structures are just some of the ‘sustainability’ concepts involved in Bentz’s research.

Viewing ‘sustainability’ from a global perspective, there are only so many construction materials available on this planet. However, despite limited material types, their applications can be vastly different. The surrounding landscape of a building in Toronto is vastly different from a structure in Abu Dhabi. “This is why ‘sustainability’ issues are not taught as a single set of rules like design code regulations,” says Bentz.  “Instead they represent more of a way of thinking and that is partly why we teach ‘sustainability’ in all four years of our program.”

What important changes does the Professor foresee in the future?

Firstly, the availability of timber for large structural projects. “The stuff grows on trees,” he quips.  Another is the potential for large carbon taxes – much larger than current proposals, which could change our concrete mixes. Rather than designing with a small amount of high performance (and high strength) concrete, we might move back towards the older methods of having larger structural elements with a lower carbon footprint per cubic metre.

The most precipitous change for the professor will relate to cement production. Today, cement requires the burning of coal, which is a long-term problem. A cheap and greener method to create concrete would be a game changer for the Professor and industry at large.

Professor Marianne Hatzopoulou
RESEARCH FOCUS: Air quality, transportation and green house gases in cities

Disconcerting but repairable – describes Professor Marianne Hatzopoulou’s position on the word ‘sustainability’. She believes the term is too widely used and more often than not conveys naught. “I don’t think we should stop using it, I actually think we should straighten how it is used,” remarks the Professor.

Like Professor Posen, Hatzopoulou thinks of ‘sustainability’ as the triple bottom line. She does not appreciate the expansions and reimagining efforts people make corrupting triple bottom line’s simplicity. To the Professor, it is a straightforward concept: “We must evaluate the consequences of our decisions on the natural environment, on people and on the economy. Because without a growing economy, I don’t believe that we can be creative or sustainable,” says Hatzopoulou.

‘Sustainability’ drives her research where she specifically looks at air pollution, green house gases and transportation. She admits that her work cannot improve an entire system but, when combined with other research, there can be great change. “I don’t think any researcher can claim that their work on its own will improve the ‘sustainability’ of our cities and society but coalescing knowledge is what really matters.”

In an increasingly complex world, Hatzopoulou’s work on air pollution involves understanding the problem before outlining solutions. Transportation sources create the most air pollution in cities but there is more to the equation. Because air moves, travels, mixes and disperses, assigning responsibility is difficult. The Professor notes the motivation, not just the source of pollutants, is complicated. Those who drive may choose to do so because they do not have access to more “sustainable” forms of transportation. Policy-makers can only affect change within the constraints of their budgets. The automotive industry first and foremost must respond to customer demands. There are many factors to consider and her work looks to account for all.

Though Hatzopoulou may be dismayed by the use of ‘sustainability’ overall she believes Canadians are particularly well versed on green options. “The problem is not a lack of education, the problem exists at a governmental level where long-term and strategic planning is needed to address our uncertain sustainability in the future,” she says.

Road transport emissions and urban air quality have obvious implications to the overall health of our planet. The Professor believes one major change in the future will be autonomous vehicles and all other forms of automated transportation systems. Their ramifications on energy consumption, greenhouse gas emissions and air pollution will shape our cities and the lifestyles for all our residents.

Professor Lesley Warren
RESEARCH FOCUS: Cleaning dirty water from mineral extraction activity

Sustainability through a southern Ontario lens – is what Professor Lesley Warren calls it. In her research, when discussing the importance of ‘sustainability’, most people view the issue with an urban bias.  This is not a problem exclusive to Ontario – throughout the world, residents of urban areas often have a louder voice as over 60% of the world’s population lives in cities.

When thinking of ‘sustainability’ Prof. Warren explains people often overlook the integral role rural and underdeveloped areas of the country play in the ‘sustainability’ of our cities. “From the screens you read your emails on, to the fuel used to power commuter traffic, land far from urban centres has a direct impact on city green efforts,” Warren says.

The Professor is cautious when discussing ‘sustainability’ noting it is an ambiguous and at times pejorative term, which many exploit to oversell products, ideas or initiatives. “It is important to understand the deliverables for green efforts. Without full agreement on desired results, the word is more about marketing than driving tangible solutions,” states Warren.

An effective ‘sustainability’ definition begins with experts uniting and coalescing knowledge from across disciplines and contexts. She reiterates the complex nature of the term, noting that the many stakeholders and perspectives influence the term’s meaning.

City policies have great impacts on rural communities with close ties to the mineral extraction industry; mining wastewaters produced hundreds of kilometers away from urban environments have lasting impacts on cities’ health. Considering the interdependence, our population must come together and consolidate its efforts.

Warren recalls a poignant comment said to her years ago. After mining activity had contaminated the only water supply in a farmer’s African town, he remarked, “You can’t drink money.”  This statement has stuck with the Professor driving her efforts to measure ‘sustainability’ in more than dollar and cents. She regards stewardship, life quality and economic impacts as critical considerations to elicit the best results for the planet.

Collaborating with many mining industry leaders in her research, Warren points to the environmental champions. These advocates not only are reacting to problems, they are adopting proactive tactics. They are minimizing impacts and mining’s environmental legacy for future generations. Mineral extraction is important for the medical equipment discovering new treatments, for the microprocessor in our phones connecting loved ones across the world and for fertilizers responsible for our global food supply. And as we continue to meet our resource demands we can do so mitigating our environmental impacts.

An issue Professor Warren looks to address in the importance of sustainability is in water. It is a precious and finite resource and something the mining industry needs in vast quantities. In areas prone to water scarcity there are competing needs to address. Once minerals are extracted, the wastewater produced must be dealt with safely and securely. Upstream R&D is a focus for Warren. Engaging with industry partners, the Professor and the Lassonde Institute of Mining (LIM) and the new Lassonde Mining Hub (LMH) are pioneering new technologies that will dramatically transform the industry and create proactive solutions.

TRENDING HASHTAG OR MOBILIZING QUESTION?

It is clear that the S-word has been reduced to a hashtag moniker for a trending movement. However, the nobility of effort is something to be celebrated. Mobilizing effects are palatable if the repetition does not alienate people first. Regardless of the trend, the word must amount to more than limited improvements and prioritize significant impacts. Clearly, to do so, definition is important.

The way public discourse uses the word ‘sustainable’ is undoubtedly unsustainable. Green. Eco. Globally-conscious responsibility. The list can go on. Whatever the word choice, the motivation is there and is important to all engineers.

Evolving eco-conscious terminology aside, our professors move past the hype and define ‘sustainability’ for impact and solutions. Here is a recap:

  • Professor Posen wants more numbers.
  • Professor El-Diraby wants to move past generic ideas to thoughtful examination.
  • Professor Bentz wants to ignore the over-use and see the term for that which it inspires.
  • Professor Hatzopoulou wants the term straightened-out.
  • Professor Warren wants a dual-lens from both urban and rural perspectives.

Students win grand prize in the 2017 U.S. Department of Energy’s Race to Zero design competition

The team beat out over 50 submissions from four countries during this eight-month competition. The project focuses on building sciences, green energy initiatives and sustainable city development

Creating homes in the forgotten Toronto back laneways, LaneZero’s design offers stylish living driven by sustainable development.

Downtown location with loft-style, open-concept living featuring a bright kitchen, second-floor balcony and no energy bills for life.

This net-zero listing is a surprising addition to the rear garages and often neglected buildings dotting Toronto back alleys; but for a city facing a housing crunch this design contest winner might be the sustainable solution needed.

Recently Jason Gray (CivE MASc student) and U of T alum Kevin Wu Almanzar (CivE 1T6) teamed up with students from Ryerson to take home the grand prize in the 2017 U.S. Department of Energy (DOE) Race to Zero competition. Tackling green energy and building science challenges, the team addressed some unique problems plaguing Toronto with their market-ready design concept entitled, LaneZero.

LaneZero is a commercially viable design providing current homeowners the ability to transform pre-existing vehicle storage units to net-zero, single-family dwellings. Common garages are an untapped potential, which could transform our city.  With City Hall actively pursuing sustainable transportation alternatives, current forecasts suggest the need for garages will dramatically decrease.

Standing out from its competition, LaneZero responds to property owners’ needs today. The design offers a modern living space, affordable construction and great returns on initial investment given the net-zero mechanical performance.

“LaneZero shows that there is a viable option to help mitigate Toronto’s housing crisis. The fact that it can be competitively built while being net-zero, is in itself a large achievement. We expect LaneZero will encourage and help inform future Toronto by-law changes, which have been slow to develop and evolve,” Wu Almanzar notes.

Working within existing city landscape and infrastructure, the team used the laneways of Christie Pits as inspiration, and set out to identify a net-zero energy solution for the neighbourhood.

Prospective LaneZero sites are small and forced the team to revaluate traditional green building strategies. In typical low-energy homes, the necessary insulation needed in the building envelop to minimize thermal bridging requires walls up to three times larger than conventional building methods. The LaneZero design balanced the home’s footprint with wall thickness for optimal living through energy modelling and parametric analysis.

 

LaneZero’s winning architectural rendering of their market-ready Toronto laneway design.

“Our design serves to activate the laneways of Toronto and foster a community in spaces that were historically underused,” said Gray. “The laneway concept gives homeowners the opportunity to establish income properties on their existing lots and provides housing alternatives in the Toronto market. For those that don’t want to go the condo route – this is a great housing option.”

With 15 team members from a variety of fields like architecture, building science and mechanical engineering the students collaborated on every decision and development phase. From competing design needs requiring compromise to conflicting construction requirements, the team harnessed the complex, iterative process to spark ingenuity and innovation.

After weeks of comparisons and adjustments, the team obtained net-zero energy unlike other submissions who failed to meet the energy target. Using modelling software to determine an optimal design, the team considered the quantity of daylight penetration year-round, environmental impact and overall building costs.

Gray and Wu Almanzar spearheaded the envelope system design to minimize heat loss, protect the structure from damage, and help ensure year-round comfort. They worked alongside the architecture, mechanical, and indoor environmental quality teams to ensure comprehensive and fully integrated systems.

One creative and interesting consideration the team addressed was the limited roof space on laneway homes for solar panels. They employed passive solar and mechanical design concepts to take advantage of free energy and technological enhancements.

“For example, LaneZero leveraged the low-angle sun in the winter time with large south facing windows to maximize free heat gains while offsetting the heating demand. Appropriate shading for the summertime limited the amount of direct solar radiation entering the building and lowered the cooling demand,” explains Gray. “On the mechanical side, using an innovative heat pump design, the heating, cooling, and domestic hot water were all provided in a highly energy efficient manner. Other strategies, such as a large amount of insulation for the envelope assemblies, continuous thermal layers, and energy efficient appliance selection contributed to achieving the net-zero goal.”

The design lauded for its architectural finesse, comprehensive building science analysis and a unique vision for the future of sustainable cities, won in the Attached Housing category and the grand prize across all categories. The team is investigating future expansions and potential opportunities for project applications.
