Building in a Changed Climate

The building industry has more challenges to meet than ever before - and according to climate science, we have 12 years to cut carbon emissions in half.

How do we simultaneously design for the extremes of a changed climate and build in a way to reverse those changes? Will ever more complex technology help us meet the challenge? We’ve seen some very sophisticated green buildings perform poorly, and some simple structures perform exceptionally well.

The 2019 Green Building Festival will look at both simple and complex strategies, techniques and technologies to inspire the building community in reaching the goal of zero carbon.

GBF19 programming features:

- An office building in snowy Austria that regulates comfort and temperature all without a mechanical system
- A movable building envelope that uses Phase Change Materials to collect and release thermal energy
- Active House versus Passive House projects and approaches

Presentation Outline

It is time for our industry to act. Buildings and development patterns today undermine our physical, mental and emotional health. Buildings and development patterns also destroy habitat and migration paths through change in land use, resource extraction, pollution and emissions, and through the degradation of water sources and wetlands. Our industry is in the midst of a massive shift from the industrial to the digital age. This has real, and positive, implications for the future well-being of all species on Earth.

In this session you will learn how and why to:

  1. Design for life, not machines
  2. Protect all waters and wetlands, discharge nothing to the oceans
  3. Restore and protect all forests, keep cities green
  4. Restore and protect eco-corridors, abandon the paved grid
  5. Use solar first
  6. Embrace distributed energy systems first
  7. Limit manmade CO2 emissions to 22GT, discharge no toxins or pollutants to the atmosphere
  8. Regulate EMFs Mandate EPDs Build only what is needed, design to human scale
  9. Design for speech music and dance, eliminate noise pollution, restore natural sounds
  10. Restore natural connections
  11. Measure happiness first
  12. Balance financial, production, social, human and environmental capital

Dr. Brent Constantz Ph.D.
Founder, Chief Scientist, and Chief Executive Officer, Blue Planet Ltd

Carbon negative concrete sounds impossible. It’s on the way.


Brent Constantz is a serial Silicon Valley entrepreneur and the inventor on over 100 issued US patents, with more currently pending.

He was a Consulting Associate Professor teaching biomineralization, carbonate sedimentology, mineralization of bone, and The Role of Cement in Fracture Management at Stanford University. In the 1980s Constantz discovered the basic process used by corals to form their skeletons in his doctoral studies. He used this to develop modern biological bone cements, which are found in most orthopedic surgery operating rooms performing orthopaedic surgery globally. In 2007, he launched his efforts to address climate change by creating a sequestered CO2 cement for use in concrete that sequesters carbon dioxide using a method that is scalable and economically and technically sustainable. In 2012 he launch Blue Planet to make sequestered CO2 aggregate for concrete.

A Fulbright Scholar, Dr. Constantz has been awarded many grants from governments, has testified before both the US Senate and the House of Representative about solutions to Climate Change, has won a number of awards and honors, and regularly contributes to philanthropic causes.

Presentation Outline

Blue Planet Ltd mimics the way coral uses carbon to build itself. The process combines captured CO2 and recycled concrete or slag aggregate to create synthetic limestone and sand. These carbonate rocks eliminate quarried limestone. Carbon is diverted from the atmosphere and stored permanently in concrete, the single most widely used solid material in the world.

It gets better. 55 billion tons of rock is mined every year worldwide for buildings and roads and 70% of it is limestone containing 22 billion tons of CO2. More than half of this CO2 could be consumed by replacing mined aggregate with synthetic limestone. After water, aggregate is the most transported material on Earth. The transportation and product delivery infrastructure for delivering carbon sequestered aggregate is already in place in every country and at every site in the world that is producing concrete, asphalt and road base thus avoiding CO2 related to mining and transportation. Additionally, when CO2 is captured from cement plants, the Portland cement component of concrete can be made carbon-neutral, eliminating the need to reduce Portland cement content in concrete.

Creating aggregate from CO2 is one of the few highly impactful, globally sustainable means to significantly address climate change, since a new infrastructure is not required. Beyond this, no retrofit of existing concrete plants is necessary. The funding to purchase aggregates is already in-place globally, and mainly part of a government procurement process, creating credit-worthy off-takers, and allowing governments to use their procurement power to mitigate CO2 and drive the transformation from mining.

Presentation Outline

The world is becoming ever more complex, not least for building owners and users. Many buildings vie to outdo one another with ever more technically sophisticated ways to save energy, rendering the human beings within them no more than disruptive elements being regulated and even limited by building mechanical services.

2226 is an alternative model which is elegantly simple. Developed using the elemental means of architecture, 2226 buildings are constructed with the focus back on occupants: 22°- 26° C is precisely the range human beings experience as a pleasant room temperature. Without wasting energy on heating, ventilation or cooling, 2226 buildings like the architect’s office building in Lustenau, Austria bring investors, building owners and users back to their comfort zone, with top quality and little technology.

Presentation Outline

Today’s cities are responsible for 75% of the world’s energy consumption and are emitting 80% of man made carbon dioxide. Over the last decades, urban agglomerations have been very successful in absorbing population growth and drawing in rural population. They are home to more than 50% of the world’s population. Acknowledging these facts and facing the process of rapid urbanization, demands for new strategies reducing CO2 emissions and energy consumption.

The lecture will mainly focus on the development and realization of the first ‘Active Energy Building’ as one possible answer to these urgent questions.

Applied trans-disciplinary research is foundation for the architectural work of falkeis2architects and includes acoustical phenomena, building integrated energy production and sustainable structures as well as ‘biological approaches’ to building, structural and urban design, and the social impact of technological innovations. The lecture will briefly feature some of these research activities.

Based on intense research the Active Energy Building successfully implements a building integrated energy production system. PV-tracking systems and PCM-climate wings, part of a moving building envelope, harvest solar and interstellar radiation producing solar power and controlling the building climate.

The Active Energy Building also provides high capacity to adapt to changing spatial requirements, achieved by a most effective load bearing structure.

The project aims at delivering a contribution to improve urban living conditions and energy demands and is a built example for decentralized urban energy production.

Sustainable Technologies Evaluation Program (STEP) Heat Pump Research Findings


For the past six years, Erik has been an Analyst with the Sustainable Technologies Evaluation Program (STEP) of the Toronto and Region Conservation Authority where he has been a scientific lead on pilot projects evaluating the performance of emerging low-carbon technologies – focusing primarily on photovoltaics and heat pumps.

Prior to STEP, Erik worked in industry for Ecologix Heating Technologies, a small-scale manufacturer of innovative cold-climate heat pumps. He is a Certified Measurement and Verification Professional (CMVP) and holds a Master’s of Applied Science in Engineering Physics, a Swedish Magisterexamen in Solar Energy Engineering, and a Bachelor’s Degree in Physics..

Presentation Outline

The Sustainable Technologies Evaluation Program (STEP) of the Toronto and Region Conservation Authority (TRCA) recently piloted two emerging low-carbon heating and cooling technologies. In the first pilot, performance measurements of a natural gas driven heat pump (GHP) were used to estimate the savings of energy, cost, and carbon, in different applications.

The study found that installing the GHP in a preheat capacity for a conventional DHW boiler (i.e. additional system complexity) could result in significant savings and a reasonable payback. In the second pilot, measurement and verification of ductless multi-split air-source heat pump retrofits suggested that the best cost-performance is likely achieved with a simpler variant of ductless heat pump technology. 

This mini-presentation will detail key findings from each project and direct delegates to additional resources where they can learn more..

Simple solutions creating complex problems: overcladding in post-war apartment buildings


Marianne Touchie is an Assistant Professor jointly appointed in the Departments of Civil & Mineral Engineering and Mechanical & Industrial Engineering at the University of Toronto. Prior to joining the U of T faculty in 2016, she was the Building Research Manager at the Toronto Atmospheric Fund and a Postdoctoral Fellow in the Department of Civil Engineering at the University of Toronto. Her research focuses on improving the energy performance and indoor environmental quality of existing buildings to make them more comfortable, healthy and sustainable through comprehensive retrofits.

Most recently, Dr. Touchie and her colleagues have been studying the interaction between energy performance and indoor environmental quality in Toronto’s aging multi-unit residential buildings including a number of buildings used for social housing.

Dr. Touchie teaches undergraduate and graduate courses in both Civil and Mechanical Engineering including Building Science and HVAC Fundamentals. She is also the Vice President of the Building Science Specialist Board and the Vice Chair of the Technical Committee on Physiology and Human Environment at ASHRAE.

Presentation Outline

Single-glazed windows, no thermal insulation, significant air leakage, pressurized corridor ventilation systems, hydronic baseboard heating – all characteristics common to hundreds of post-war apartment buildings in our region. Overcladding and window replacement retrofits are becoming more common as a way to address these issues and improve envelope thermal performance and thermal comfort. However, by only considering envelope improvements, existing challenges with the building HVAC systems become even more problematic.

By examining both local and international studies, we’ll see how important it is to consider alternative ventilation strategies when undertaking an overcladding retrofit and explore the consequences of not doing so.

Passiv for the Masses: Tunneling through the cost barrier through innovative design and production methods


Terrell Wong is an architect with over 30 years experience.  Her passion for the environment and design has greatly influenced her career. In 2006, Terrell lead the winning team to the National Archetype Sustainable House Award. Their “Building Blocks” modular home concept was constructed at the Toronto and Region Conservation Authority’s Kortright Centre as a showcase for sustainable design.

Terrell was a founding member and is the President of Passive Buildings Canada, a national membership-based, non-profit organization that promotes the Passive House concept.

Recently, Terrell published Passive Buildings in Canada. This book is a snapshot in time of these buildings in Canada. The goal is to present these excellent designs in an easily comprehensible way to architect, engineer, builder and future home owners alike. This book encompasses buildings from British Columbia to Nova Scotia and building types as diverse as single family dwellings to high rises.

Presentation Outline

For many building teams, it is an almost impossible challenge to simultaneously deliver high performance, cost efficient buildings while maintaining high customer satisfaction and profitability. It is not uncommon for high performance commercial buildings to cost 10% - 20% more to build than conventional buildings. Cost efficient high performance buildings rely on holistic analysis and implementation of design, construction and testing to produce consistent results.

This presentation will explain the history and basics of Passiv design principles. It also examines integrated project delivery methods essential within the design and construction team taking joint responsibility for decisions and actions from schematic design through project construction, commissioning and monitoring. Built examples and areas for capturing money typically left on the table in conventional design-bid-build project delivery situations will also be discussed.
