New Sustainable Essentials Titles

sustainable building essentials books

Endeavour is proud to be the series editor for the Sustainable Building Essentials Series from New Society Publishers. Now numbering 11 titles, the series is on track to be the go-to resource for the homeowner, designer and builder seeking to make the most people- and planet-friendly buildings.

Released in 2018 are four great new titles:

Essential Natural Plasters, by Tina Therrien and Mike Henry. This is the recipe book and resource that all plasterers have been waiting for! Combining many years of experience, the authors describe how clay and lime plasters work, and assemble time-tested recipes from plasterers from around the world.

Essential Rainwater Harvesting, by Michelle and Rob Avis. The two principles at Verge Permaculture have created the ideal resource for anyone looking to harvest and use rainwater from their building. From simple systems for irrigation to complete household, potable use, the book has all the information you need to do the calculations, systems planning and installation of your rainwater system.

Essential Composting Toilet Systems, by Ann and Gord Baird. No other topic lacks solid, well-researched information than composting toilets. Gord and Ann Baird from Eco-Sense have put together an incredibly helpful book that looks at how and why composting works, and review the many types of systems on the market. From homemade bucket toilets to high-tech systems, this book is everything you need to know about choosing the composting toilet that is right for you.

Essential Rammed Earth Construction, by Tim Krahn. Rammed earth is beautiful, durable and can be eco-friendly. Tim Krahn, an engineer with Building Alternatives who has been working with and designing for rammed earth for many years, examines rammed earth in its raw and stabilized forms, and provides all the details you need to know to create your own rammed earth building.

Building for climate drawdown

carbon capture and storage in buildings

Endeavour Centre is committed to helping reverse climate change by creating buildings that are carbon capture and storage devices. Our buildings store more carbon in their materials than was emitted in making the materials… climate positive building. Add this to our net zero energy practice and use of onsite renewable energy and we can change buildings from being a leading cause of climate change into a leading solution!

Chris Magwood recently presented to Passive Buildings Canada about how this can be done, using Endeavour Centre buildings as case studies. You can watch a video of the presentation to learn more:

Waste wood structural columns

There is an incredible amount of “waste” wood that is thrown into landfills or otherwise left to rot because it is not long enough to be used vertically in a building. So we take that wood and stack it up to make load bearing columns in buildings. Offcuts from log home factories, discarded 2x4s and 2x6s and dead tree limbs all find permanent, structural homes in our waste wood columns.

Prefabricated straw bale wall panels

Prefabricated straw bale walls

Endeavour has a long history of working with prefabricated straw bale wall panels. We were the first to make panels in 2000, and have continued to implement versions of panelized straw bale systems in residential and commercial building. To date, we have been involved in over 20 prefab straw bale projects!

In 2017, we built the Zero House with a “dry” prefab straw bale system, using no form of plaster on the walls.

Essential Prefab Strawbale Construction

Straw bale walls have a remarkable array of benefits, but they can be labour intensive and are difficult to build in a mainstream context. By prefabricating the plastered straw bale panels, they can be delivered to a job site for the same cost as conventional framed walls, and still have all the environmental benefits. And they can be produced quickly and easily in small, local micro-factories, making it possible to bring the benefits of bale walls to any region.

Chris Magwood published his book Essential Prefab Straw Bale Construction in 2017, which gives comprehensive coverage of the topic, including details for numerous different prefab systems.

Endeavour will be offering a workshop on prefab straw bale systems in 2018.

Below is an older slide presentation about prefab straw bale wall systems:

Round straw bale columns

Many people use small, square straw bales to make buildings, but we used the big round bales as load-bearing columns in a building! The big rounds are incredibly dense and uniform, and we lab tested them to 120,000 pounds of load! They are quickly and easily assembled and make a truly sustainable “frame” for a building.

What is Natural Building?

There is no universal definition of “natural building” but Wikipedia does a pretty good job of explaining the basics of natural building. If you want to be inspired by lots of great photos of natural building around the world, Talking Natural Homes is a great place to start.

Here at Endeavour, our full time Sustainable New Construction and Sustainable Renovations programs focus on the use of natural materials in the context of high-performance, code-approved buildings where the natural materials palette is combined with responsibly manufactured products and high-tech mechanical systems. The natural building intensive focuses exclusively on the use of natural materials and simple, home-made systems.

What Makes Zero House – BiPVco Solar Modules

BIPVco_black

This is one in a series of blog posts about the materials we’ve chosen to build our Zero House project…

What are BiPVco Flextron solar modules? BiPVco specializes in the manufacturing of building integrated photovoltaics, that is, solar modules that are a part of the building, rather than “add-ons” that must be fastened over or onto the building.

Where are BiPVco Flextron solar modules used in Zero House? The standing seam metal roof on the south side of the building receives 32 modules that each produce 120 watts of power, for a total of 3,840 watts (3.84 kW). We use a company that does sheet metal fabrication Texas. These parts are hand delivered to us.

How do BiPVco Flextron solar modules help achieve the Zero House goals? 

  • Zero net energy use – The solar energy harvested from the BiPVco modules over the course of a year will equal the amount of energy it takes to operate Zero House.
  • Zero carbon footprint – The modules use a flexible, CIGS thin-film technology that does not require the tempered glass or aluminum frames of typical modules, and combined with the elimination of mounting racks, the BiPVco modules have a significantly smaller carbon footprint than other solar modules (67 kgCO2e/m2 versus 242 kgCO2e/m2 for monocrystalline modules, according to the Inventory of Carbon and Energy V.2).
  • Zero waste – The flexible modules are highly resilient and require only a fraction of the packaging for glass-covered modules.

 

Other reasons for using BiPVco solar modules:

  • Durability – We don’t need to make any penetrations in the roof surface to mount the BiPVco modules, which is a huge advantage in terms of long-term durability of the roof. There is also no glass to break in case of hail or falling tree branches.
  • Affordability – The modules are comparable in price per watt to standard modules, but the savings on racking and mounting make them a very attractive option price-wise. Roof trusses do not need to be sized to take an extra load, as the modules are very light weight and don’t present any wind uplift issues.
  • Prefab – We can mount the modules to the roofing and ship them together to the building site, eliminating a separate shipping step and construction step on site.
  • Code compliance – BiPVco does not yet have CSA certification, and requires a field inspection.

Any drawbacks to using BiPVco solar modules?

  • The adhesive that binds the modules to the metal roofing seems very strong, but only time will tell how it holds up the Canadian climate.

What Makes Zero House – 475 High Performance Building Supply

Final Canada logo with type

This is one in a series of blog posts about the materials we’ve chosen to build our Zero House project…

What is 475 High Performance Building Supply?  475 High Performance Building Supply provides essential building knowledge and components to building professionals, focusing on materials that provide the best air tightness, ventilation and durability.

 

Where are 475 products used in Zero House?  There are 475 High Performance Building Supply products used throughout the Zero House building, including:

  • Mento 1000 house wrap – A 3-layer airtight, vapor-open housewrap that is an extremely strong weather resistive barrier (WRB). It provides superior weather protection and can cover most exterior building substrates. It has an actively vapor open, monolithic layer of TEEE film that is extremely waterproof – and outperforms perforated/stretched WRBs both in outward drying potential (38 perms) as well as airtightness.
  • Intello Plus – A “smart” vapor retarder that provides a first class air barrrier for thermal insulation in roofs, walls and floors. It gives structural systems a previously unachievable degree of protection from structural damage (from condensation), even under extreme climatic conditions, due to its intelligent vapor retarding properties.
  • Tescon Vanna – Air sealing tape is a long-lasting, robust solution for building airtightness. Used to seal the air control membranes over our prefab panels on the exterior and interior side.
  • Tescon Profil – Same great airsealing, weather resistance, and vapor profile as Tescon Vana, but with a 3-split release backing to make airtight connections and waterproof seals at corners quickly and easily.
  • Extoseal Encors – A watertight adhesive tape with high adhesion for creating window sills.
  • Roflex pipe gaskets – Creates durable and airtight seals around pipes, ducts and cables which pass through membranes, wood-based panels and other substrates.

How do 475 products help achieve the Zero House goals?

  • Zero net energy use – A building must be air-tight to be truly energy efficient, and the air-tightness products from 475 High Performance Building Supply help us to ensure that our building is free of costly leaks and that our air sealing will be durable and long-lasting.
  • Zero toxins – All Pro Clima tapes and membranes are free of solvents, VOCs and softeners

Other reasons for using 475 High Performance Building Supply products:

  • Waste – Most of the ProClima products are 100% recyclable
  • Workability – The membranes and tapes are very rugged, and don’t stretch or deform. They are much easier to install than other house wrap and vapor retarders, and it is easy to install without waves or folds. The tapes adhere extremely well and can be applied smoothly and accurately.
  • Moisture control – All the products have top ratings for moisture control in their intended locations, and together allow us to safely create a vapor permeable wall, roof and floor assembly.
  • Durability – The membranes and tapes are long-lasting, and the excellent moisture control characteristics help the building to last a long time in a wide variety of humidity and weather conditions.

Any drawbacks to using 475 High Performance Building Supply products:

  • 475 recently added a Canadian warehouse, so shipping times are greatly reduced. Products must be ordered directly from 475.
  • Many products do not have Canadian code compliance documentation, so even though they outperform conventional options, builders may have to use Alternative Compliance pathways to get code approval

Air sealing materials from 475 High Performance Building Supply are a key part of the high performance and energy efficiency of our projects at Endeavour. It is our hope that more builders will turn to these top-notch products in the move toward more energy efficient buildings.
