GWP & Accountability, Sustainable Engineering Practices By Paul Lowes

The impact of climate change has reached a point where it can no longer be ignored. Federal and Provincial governments have implemented rebates and taxes, to incentivize industry and citizens to do their part to address climate change. Most companies in North America have implemented strategies and targets to mitigate their impact on the environment. Companies express these efforts in Environmental Social Governance (ESG) policies and reporting. Nowhere is this movement more profound than the construction industry.

Topics include:

  • Manufacturer’s products with lower Global Warming Potential (GWP) and EPD. Builders must meet the evolving regulatory requirements of the municipalities in which they build; The Low Carbon Home Builder Coalition (LCHC) constructs homes that reduce operational energy and water consumption with products that have a low GWP.
  • Carbon rating systems like HERS and CAGBC Zero Carbon
  • How the LCHC can empower builders to measure and report CO2 reduction for Environmental, Social and Governance (ESG)

The virtual webinar will be hosted via Zoom on November 22nd, 2023 from 10:30am to 12:00pm. Please join us and register at Eventbrite via https://www.eventbrite.com/e/gwp-accountability-sustainable-engineering-practices-by-paul-lowes-tickets-756398828257

Sustainable Thought Starter – Counting Carbon for the LCHC

This year, like many others, was my first time attending the Low Carbon Home Builders Coalition. It was a great opportunity to network with other professionals such as Builders, Manufacturers, Contractors, City Officials, and many other industry stakeholders who share the vision of creating sustainable and affordable housing for our province. There were many great speakers at this event talking about Codes, Carbon, and the future of our housing. Furthermore, highlighting an important topic that was discussed is Combination Hybrid Heat Mechanical Systems, which is a cutting-edge, cost efficient technology that can reduce greenhouse gas emissions and energy costs. This heating and cooling strategy will keep the utility bills as low as possible for the occupants of the home and will be able to comfortably condition the home during any season of the year. In my opinion this Hybrid Heating solution is one of the key solutions to deal with carbon emissions while also maintaining affordable living. It taps into Ontario’s biggest energy source – off peak electricity surplus.

As we move towards reducing our carbon footprint it is very important that all parties involved in the building industry understand the target. Net Zero being the buzz word of today, understanding what Net Zero means and how it can be achieved is important for individuals, businesses, governments, and all parties involved. Currently, the net zero homes that we are building and labeling fall short of the targets we are trying to achieve. In that there actual performance is “not” zero. We need to continue the conversation so that the industry and innovators can support each other in their common goals.

Being a Residential HVAC Designer working with McCallum HVAC Design Inc, we consult with clients daily about making decisions regarding mechanical equipment and building envelope. The future of energy efficiency starts with the selection of insulation, the type of heat source and the control strategy.

I am hoping that being on the board of the Sustainable Housing Foundation will give me opportunities to meet new like-minded individuals, preview into what code changes are coming in the future and how I can better prepare myself and my company, McCallum HVAC with the continuously changing landscape of energy efficiency and low carbon technologies. Not only to know about the change, but also to give myself a voice in the discussion.

Sustainable Thought Starter – ESG, GWP and The Low Carbon Home Builder Coalition

Here are some ideas that Paul Lowes would like you to examine when it comes to the future of residential home building.

The impact of climate change has reached a point where it can no longer be ignored. Federal and Provincial governments have implemented rebates and taxes, to incentivize industry and citizens to do their part to address climate change. Most companies in North America have implemented strategies and targets to mitigate their impact on the environment. Companies express these efforts in Environmental Social Governance (ESG) policies and reporting. Nowhere is this movement more profound than the construction industry.

Builders, manufacturers, and governing bodies all recognize the significance of their part in helping to reduce the carbon footprint of the residential and commercial construction industries.  These organizations work towards implementing building codes that are designed to build homes with lower energy consumption and CO2 emissions. Manufacturers are tasked with producing products with lower Global Warming Potential (GWP). Builders must meet the evolving regulatory requirements of the municipalities in which they build; The Low Carbon Home Builder Coalition (LCHC) constructs homes that reduce operational energy and water consumption with products that have a low GWP.

Sustainable Thought Starter – Building a Sustainable Housing Industry

Building a Sustainable Housing Industry

 

Affordability, or the lack thereof, has been front of mind for a long time.  Our industry has been screaming it from the rooftops for many years.  We’ve seen the tsunami coming, and the current Ontario government has finally decided to make some welcomed changes with Bill 23, More Homes Built Faster Act, 2022.  Increasing supply will help with affordability.

 

One factor limiting the supply of new homes is a shortage of skilled labour in the GTA. The Honourable Monte McNaughton, Minister of Labour, Immigration, Training, and Skills Development, announced April 24, 2023.  This funding will provide in-demand residential construction training to a new cohort of unemployed and underemployed job seekers to shrink the skilled trades gap in the province. The Job Ready Program provides builders with prescreened prospects and the necessary on the job training with support for a paid placement for a three-month test drive. For future employees, it starts with a one-hour info session and candidate interviews as a resource for builders.  The program design is to mitigate risk for both parties.

Sustainable Housing Foundation Dinner

Introducing the Low Carbon Home Builder’s Coalition

 

Here’s a question worth asking. In Ontario, we have a surplus of off-peak electricity and challenges with fresh water supply and waste treatment capacity. What could be the best way to manage our energy and water needs and reduce CO2 emissions? For the answer, let’s look to the Low Carbon Home Builder Coalition (LCHC).

The idea behind the LCHC is to annually benchmark as many homes as possible to see how progress in new home construction is stacking up against federal commitments — a type of report card for residential builders. In 2023, the coalition effectively got 527 cars off the road and saved their home buyers 1.6 million dollars in energy costs annually. With respect to local green building standards, the coalition is working to preserve a builders choice on how they meet local requirements. For example with Pickering’s Green Building Standards, HERS energy ratings and HERS H2O labels are mentioned directly. Please think about joining the coalition for a Fall dinner meeting, Tuesday September 26th 2023 from 5:30pm – 8:30pm at Thornhill Golf and Country Club to find out more. It’s on us!

Topics will include:

  • The HERS carbon rating system
  • The Hybrid House Approach
  • Navigating Code Harmonization
  • Green Building Standards

 

Sustainable Thought Starter: Local Leadership – Rewarding Leadership and Creative Thinking

What makes good leadership? We know that poor leadership usually consists of simplistic thinking or fundamentalism. In contrast, balancing pros and cons — and preserving balance and choice — is key to effective leadership.

In training sessions, I usually ask the participants “yes” or “no” questions — but I rarely get commitment to either response. Maybe people are afraid of suffering the disapproval of the group. There’s nothing wrong with not knowing the answer, but asking yourself the question is what’s most important. Good leadership is about constantly asking good questions.

Clean Energy and Renewables – By Christian Rinomato and Grace

What if we could live in a world powered by clean energy? The members of the Sustainable Housing Foundation will be hosting a webinar to try and answer this question by understanding the application of Renewable Energy in the home building industry. The virtual webinar will be hosted via Zoom on May 17th, 2023 from 10:30am to 12:00pm. Please join us and register at eventbrite via

 

Topics include:

  • The countries setting targets for a  Net Zero world by 2050, more and more capital is directed at new clean energy projects.
  • The increase globally in the use of renewable energy through sources like solar and wind.
  • Impact of the Ukrainian war making the use of renewable energy a cost effective practice in Europe vs oil and gas
  • The Global renewable electricity capacity forecasted to become equivalent to current global fossil fuel and nuclear electricity capacity by 2026

 

Sustainable Housing Foundation Thought Starter – May

 

 

By Christian Rinomato of RGC Energy

 

What if we could live in a world powered by clean energy?

That reality is not too far off. Globally we have seen an incredible increase in the use of renewable energy through sources like solar and wind. As countries set targets for a Net Zero world by 2050, more and more capital is directed at new clean energy projects. Global events have also set us off in this direction such as the war in Ukrainian which increased the cost of oil and gas to unsustainable levels, making the use of renewable energy a cost-effective practice in Europe. In the United States, Biden introduced an Infrastructure Bill that would see spending in the trillions to encourage the transition to renewable energy.

“By 2026, global renewable electricity capacity is forecast to rise more than 60% from 2020 levels to over 4 800 GW – equivalent to the current total global power capacity of fossil fuels and nuclear combined. Renewables are set to account for almost 95% of the increase in global power capacity through 2026, with solar PV alone providing more than half.” – IEA

The transition to renewable energy is going to take all of us to play its role, both in adoption and acceptance. A world with no carbon-emitting energy sources is possible for a cleaner, more prosperous world.

Sustainable Thought Starter: Understanding the Law of Diminishing Returns: The Best Practice

 

Understanding the Law of Diminishing Returns: The Best Practice

 

“The law of diminishing returns means that even the most beneficial principle will become harmful if carried far enough.” — Thomas Sowell

Energy performance was introduced under SB-12 in 2012, then again at 15% better in 2017 and, very shortly, we are expecting harmonization with the National Building Code (NBC) in March 2024. Currently the Ministry of Municipal Affairs and Housing (MMAH) is proposing to adopt Tier 3 of the NBC (roughly 8% higher than Package A1), and policy makers are targeting net zero by 2030.

An important question is: where does the law of diminishing returns kick in? See graph. Ironically, the most popular programs — like net zero or Passive House — were conceived before we started accounting for embodied carbon. Building components like triple-glazed windows, certain types of insulation and concrete can also negate these emission reductions. Early experiences show that electric NZE houses cost more to operate.

Where is the sweet spot? Is net zero a reasonable goal? Time will tell.  Wood is renewable and, best of all, is a carbon sink. Trees produce oxygen and absorb CO2. Using wood in large building structures replaces concrete and steel and thus reduces the largest sources of embodied carbon in buildings.

Triple-glazed windows could be the last choice depending on a home’s size, orientation and climate. A low solar heat gain coefficient may be a more important value for comfort and efficiency than an extra pane of glass.

It has been said that the road to hell is paved with good intentions. Using more embodied carbon to save operational carbon is just adding fuel to the fire. With diminishing time and resources in a period of climate change, finding the point of diminishing returns is of utmost importance.

Hi,

Here are some thoughts that Paul De Berardis would like you to consider when it comes to the residential building sector.

There are always two sides to every story, but the general consensus is that individuals working within the residential new home industry feel they are doing their part to address climate change, whereas external organizations always feel more can and should be done.

 

While there is merit to both sides of the argument, this must also be viewed from the lens that homes are ultimately sold to consumers, who are typically constrained by financial budgets, especially considering the rising trend in mortgage interest rates, so more may not always be better for everyone. There also needs to be consideration for constructability and embodied carbon, as homes become more complex to construct through increasing regulatory requirements, and they take more time and resources to build. Government policies are pushing home builders to ramp up operations and build more homes than ever to address housing affordability, yet there is a declining workforce of skilled trades, and building regulations are only getting more onerous, counterintuitive to say the least.

Please join us for our virtual seminar, “The Low Carbon Builder Coalition” being held on March 22nd 2023 from 10:30 am – 12:00 pm for more information on this.
