Reflections on a Successful Green Building Festival 2016

October 5th, 2016

This past week I was fortunate to be able to attend the Green Building Fest, an annual event, hosted this year by Sustainable Buildings Canada and the International Initiative for a Sustainable Built Environment (IISBE). Watching the presentations was like being on an emotional roller coaster. When the various government officials presented (Glen Murray (minister of the Environment and Climate Change), Alex Woods (policy writer presenting Ontario’s Climate Change Action Plan) and Dianne Saxe, the Environmental Commissioner of Ontario), I felt depressed and hopeless based on their honest and somewhat depressing view of where we are headed. The news is not good.

I was uplifted, however, by the brilliant and well-prepared presentations from the extraordinarily talented people invited to speak to us about projects in which they are involved that are helping us adapt to climate change. The theme this year was resiliency — because we can no longer prevent climate change, it’s here, so we must prepare ourselves and our communities for the effects of extreme weather events. The presenters gave me hope that we will be able to adjust and adapt, although, make no mistake, it’s going to be messy and ugly and expensive in the beginning, but the cost of inaction is uglier, messier and even more expensive. We are at the point of no return. We need to act now and put ideas into action or future generations will pay dearly for our inaction. » Read more: Reflections on a Successful Green Building Festival 2016

Green Building is Dead….Long Live Green Building!!

July 24th, 2015

I’ve noticed that there has been a significant transition in the green building industry, especially with respect to residential building. A few of my favourite green building haunts have reinvented themselves over the past few years. Most of them started out selling green building supplies, but those that have survived are either still the loner in their geographic area with enough demand to support their business or they’ve transitioned into building services. Why? Because many of the green building products have become so mainstream that they are no longer niche. By now, the terminology “zero and low VOC” have become so common that most people will ask for these types of products — and the vast majority of salespeople know exactly what people mean when they ask for them (believe me, this wasn’t the case in 2009). Energy efficient products are everywhere and consumers have gained enough knowledge that they feel comfortable to ask the right questions. We want to know about recycled material content in our products, where they were made, and what will happen to them at end of life.

The progress that has been made in terms of general knowledge is remarkable. I attribute a lot of that knowledge with the rise in popularity of LEED. Whether the term has made it into the vernacular at the consumer level is almost irrelevant. Most builders — whether they love it or hate it — are very familiar with the certification and all of its pros and cons. But that is the point: now that the building industry is aware of it, it can work with clients who want to build better, healthier, durable and long lasting homes with better knowledge.

So, where does that leave me? In transition mode. I feel that my job is done with respect to writing about specific building materials, energy efficiency products, etc. While these issues are still important, there is enough knowledge and information out there that my news is no longer needed. I’ve covered VOCs, recycled material, energy efficiency, LEDs, water efficiency to death! On to bigger and better things! While I will leave all the previous articles up on the blog, the scope and content of the blog will transition into the bigger picture: the circular economy, extended producer responsibility, waste management, and sustainable cities. My work-life is currently focussed on these areas so it makes sense to write about them. And, as you will see, green building materials, energy and water efficiency are key pieces of these larger issues.

In the mean time, for the best information on green materials, building science, energy efficiency and green building, here are my go-to resources:

Materia: a totally awesome website dedicated to materials of the future, many of which are bio-based, all of which are interesting and different.

Inhabitat: quite possibly the best design blog out there with lots of green and inspirational ideas.

Treehugger: love this website and all the discussions that happen under articles. It is at the heart of most eco developments so if you only want to visit one site, this is the one.

Green Building Advisor: Aside from all the fantastic green building information available, the discussion forums are excellent.

Building Green: Green building guru Alex Wilson has been building green since before it was hip and trendy. He and his team are well-known for expert advice on all things green building, including materials.

Building Science Corporation: for highly detailed, thorough explanations of the latest developments in building science, this resource provides essential information.

Enjoy your reading!

 

Green Building Illustrated: Book Review

September 24th, 2014
Green Building Illustrated

Green Building Illustrated

Francis Ching is a well-known author and illustrator of books on design and construction, perhaps within the building sector his most well-known book is Building Construction Illustrated. Collaborating with Ian Shapiro on this latest book, the pair have developed a good introduction to green building for those just becoming familiar with the field, but it also serves as a good reference guide to green building for those of us with more experience.

“What is green building?”

The point of the question is to highlight the reality that it is really an evolving definition. Some buildings built to a high standard, have, upon evaluation, turned out to be less green than their standard counterparts because they use more energy than the comparative standard, whereas some net-zero or close to net zero buildings aren’t classified as green because the owner has decided not to go through the hoops necessary to become classified.

Further,  the authors address why building greener buildings is important, referring to climate change effects as well as resource depletion. They also delve into the different green classification systems that are available.What I like about this book is that after reading it you gain a basic understanding of all the elements involved in building a better, more resilient, lower impact building.

Hosting a Design Charette

Shapiro and Ching emphasize that with the development, design and construction of any building, there are thousands of decisions that are made. One decision affects another, so it means that there are trade-offs for every decision. Getting the design done right at the beginning can save time and money down the road and one of the best ways to do that is to have a design charette. A charette is like a round table discussion where every involved party can have a say in how the design will affect their portion of the building from plumbing, electrical, HVAC concerns, material selection, and occupant use post construction. Ideally charettes include the architect, general contractor, sub-trades, building owner and manager, in other words, all stakeholders.

The book is clearly illustrated and dedicates a good section to design and design issues. Getting the design right is one of the best ways to have the most significant impact on constructing a lower impact building. Again the book is thought-provoking: the authors ask “green buildings are lower impact than what?” In fact Shapiro gently takes LEED to task because the system fails to give points for designing a building that has a smaller surface area (therefore less exposure to the elements), than its standard counterpart. In other words, no points are given for designing a more efficiently shaped building than might otherwise be built. The authors explain the differences between the different green building rating systems out there, including LEED, Passivhaus, Living Building Challenge, and Green Globes.

Another perspective of the book is that it teaches readers to design buildings from the outside in, in layers. So, it looks at landscaping, site and orientation and how those factors affect the design of the building. Further, Shapiro and Ching highlight with detailed drawings, the importance of surface area on the energy efficiency of a building. In general terms, the smaller the surface area, the greater the energy efficiency of the building.

It takes only one brief glance at the chapter on windows to confirm that all those glass condos going up all over Toronto and Montreal are  an energy efficiency nightmare. Windows, in addition to having terrible insulation values, also pose potential leak problems between their frames and the building. If not sealed properly there is an extra source of potential drafts and water infiltration.

The chapter on building materials emphasizes the need to consider local, recycled and other materials with a low embodied energy. There is a handy table that shows the different embodied energy of different types of wall constructions.

One of the best features of this book is that it is an all in one reference guide for looking at how to build better buildings from design through to commissioning (evaluating a building’s systems to make sure they are all functioning properly). Once read cover to cover, it can be used as a reference guide to greener building and the different factors that need to be taken into account. While the book does not delve deep into any one area, it does provide a readable and approachable overview that’s easily understood by laypersons as well as professionals familiarizing themselves with green building practices. If I have one complaint, it is that for old people like myself, the spidery, handwritten style font is difficult to read.

Green Building Illustrated is available through John Wiley and Sons, or Amazon.

A Visit to Ottawa’s The Healthiest Home Building Store

Nadurra Flooring, through The Healthiest Home

If you’re a consumer living in Ottawa, and you’re looking for healthier building materials than the norm, The Healthiest Home is the place to start. When I was in Ottawa a month ago, Josh Gallant, the general manager of the store, gave me a tour and explained how  The Healthiest Home works. It turns out that their retail location is the tip of the green iceberg. In addition to the store that supplies a very wide selection of green building materials, it also has:

  • the retail store including architectural design services;
  • HH Commercial, a commercial group that supplies and installs interior finishings for condo developments and works on industrial, institutional and commercial projects;
  • HH Greenbuild that specializes in renovations and green builds of residential projects; and,
  • MD Ottawa, one of the oldest and largest millwork shops in Ottawa, that builds healthy cabinets and countertops.

Each business ensures that each project it undertakes includes waste minimization through the best use of design and materials. It uses materials that are lower impact on the earth and that also contribute to a healthier indoor air quality.

The store also installs all of the products it sells from flooring to paint and guarantees its workmanship and materials. I have written about many of the finishes they carry in flooring (Nadurra bamboo and hardwood, Marmoleum linoleum), paint (Mythic Paint), counter tops (Paperstone and Icestone), and even structural (Durisol). There were, however, a few brands I wasn’t familiar with, the most interesting one was a “new-to-me” product called K-tect Sustainable Building Systems.

K-tect Sustainable Building Systems is an insulated light-weight structural building material similar to Insulated Concrete Forms (ICFs). The structural panel consists of expanded polystyrene (EPS) which provides insulation, sound dampening and structure, and light-weight steel framing providing strength. Like ICFs it combines structure and insulation into one package so there is no thermal bridging and fewer materials are needed. Unlike ICFs, it doesn’t use concrete and the product is 100% recyclable at end of life. It has an R value of 4 per inch which never degrades over time. It is easy to install and can be customized for your building. Further, and perhaps most surprisingly considering the use of EPS, there is no off-gassing from the product so it has been GreenGuard certified.

Josh told me that it has become a favourite product of their build/design group and that they have now used it on many of their projects. Their clients are particularly happy with their exceptionally low heating and cooling bills.

Because The Healthiest Home believes that to be a good business is also to be a part of the community it offers free yoga classes on Saturday mornings in its warehouse.

Healthiest Home hours: Monday-Friday, 9am-6pm, Saturday 10am-5pm.

Address:

1523 Laperriere Ave. Ottawa, ON K1Z 7S9
(417 Exit – Carling Ave.)
