EkoBuilt custom home in Sydenham

Located just outside of Sydenham, Ontario near Frontenac Provincial Park, this custom home is a great showcase for what EkoBuilt can do.

The home features an open plan concept for the living, dining and kitchen area, as well as a separate office.

The master bedroom is paired with a full ensuite bathroom and there is also a second bedroom, two half baths, and a sunroom. A huge deck runs alongside the house, connecting it beautifully to the outdoor setting it occupies.

Although we offer a range of energy efficient home plans (which are often just a great starting point), we can build to any style that suits you. Contact us today to find out more.

Retrofitting an older home to Passive House standard

Next stop in our new series on retrofitting older homes: changes to attain Passive House standard. We have received many requests from readers on how to transform an existing home into a passive home.

Everyone who follows this blog is aware that our mission is to build passive whenever we can. Building to PassiveHouse standard makes the home environment healthy, therefore translating into healthy living. It also makes the world a much healthier place as our dependency on petroleum-based fuels as heating and cooling sources is removed. Finally, a passive house is much cheaper to run. You can think of a passive house as the domestic equivalent of an electric vehicle.

IPHA guidelines

EkoBuilt follows the guidelines from the International Passive House Association. There is a lot of building science behind passive, so it can get very complicated, but it can also be explained and understood very simply. From a build perspective, the world is slowly transforming to become completely passive. Certain areas of British Columbia already mandate the passive standard in order to qualify for a new building permit. It’s important for everyone to understand as it will be here in Ontario sooner than we think.

Passive House Explained in 90 Seconds from Hans-Jörn Eich on Vimeo.

The video was made by Hans-Jörn Eich, a certified Passive House Consultant (Passivhaus Institute in Darmstadt, Germany) and the founder of Pinwheel.

Why does passive house exist?

It’s simple: to replace heating and cooling dependency on gas with electricity. That said, this is only economical if the heating/cooling demand can be reduced to a point where it’s inexpensive to use electricity, and this is where design essentials come into play.

There are three essential design features in a passive home:

1. Air-tightness

It’s vitally important that heat loss is minimized through unwanted and unnecessary leakage of air. We conduct what’s called a blower door test to find the ACH (air changes per hour) a home experiences.

Most newly built homes experience ACH anywhere between 3 and 5, meaning 3 to 5 times the entire volume of air inside the home escapes each hour. This is basically a loss of heated and cooled air which can also result in condensation in the wall cavities, translating ultimately to unhealthy mold.

For newly built passive homes, the ACH rate is 0.6 and the retrofit standard is 1.0.

Old school thinking favoured this air loss, thinking it good for fresh air to enter the building and provide a natural fresh air environment. We now know this is laughable because of all the mold problems we’ve heard about with older homes. To be fair to the old schoolers, in the past, modern building techniques/methods did not exist, nor did heat recovery ventilators (HRVs), so the options didn’t exist to change this approach.

Modern building code recognizes this fundamental change. For example, since 2017 Ontario building code has made HRVs mandatory in all homes, which we were thrilled to see happen. The problem is the HRV is only required to be 50% efficient and most homes are still leaking more air than they should.

2. Thermal envelope

Currently new-build homes, according to the standard building code, are required to have R22 wall insulation, R32 roof insulation and R10 below slab insulation. By comparison, in our local area, newly built passive homes require R75 wall insulation, R110 roof insulation and R40 below slab insulation.

As a general rule of thumb, homes retrofitted to passive standard require R48 wall, roof and below slab (or floor) insulation.

3. Proper windows

For thermal comfort, it’s very important that a passive approved window is used. These are triple glazed units with insulated frames equivalent to an R12. This may not seem like much, but compared to a non-certified triple glazed window, it’s huge. With non-certified units, it’s hard to find a unit above an R4 rating.

Certified windows optimize comfort by having a high temperature interior pane (instead of being cold on the inside when it is cold on the outside). In the passive scenario, this means when it is 25°C outside, the interior pane must be at least 17°C. Non-certified triple glazed windows can be as low as 12°C on the inside under the same conditions.

For those who would like the complete building science, please have a look at the following 20-page document, Criteria for the Passive House, EnerPHit and PHI Low Energy Building Standard (pdf). You can also view four charts at the end of this article.

How can an older home become Passive?

With all of that out of the way, how does an existing home reach the Passive standard?

To be achieved in the most cost-effective manner, this approach will obviously vary depending on the home in question, but some general rules apply:

For the walls: Airtight/vapor tight permeable layers and extra insulation will need to be installed. This will mean that either the interior or exterior finish will need to be removed (the choice will usually depend on which is most cost-effective). Certified windows and doors will also be sourced.

For the roof: If the home has an attic space (most do), extra insulation will be added to that space with an airtight/vapor tight permeable membrane installed on the ceiling side. If there is no attic, then an extra thermal later will have to be installed on the interior. If the ceiling is cathedral in design, it should be simple to build the ceiling down to the required R value. If the ceiling is flat and losing height is an issue, than a vacuum panel will be used to provide a thermal barrier with minimal loss in ceiling height.

For the slab/floor:  If a basement is unavailable/unusable, then a thermal layer will be added to the existing floor cavity. If a basement is present and usable, a vacuum panel will be used to provide the thermal barrier with minimal loss in height.

Custom home projects in 2019 by EkoBuilt
EkoBuilt News & Happenings, House Design

A sneak peek at current EkoBuilt projects

We’re starting 2019 with a great variety of projects, including single family homes, a two-family shared home, a net-zero multi-unit project and a very modern passive summer camp. Read along to learn more!

Wakefield Project

Custom home projects in 2019 by EkoBuiltThis project in Wakefield, Quebec is currently under construction. The foundation was installed in November 2018 and framing started in mid-January.

The design is a custom client inspired concept which focuses on privacy from neighbors, natural light for all spaces, and abundant storage space because of slab on grade (no basement as the property is on bedrock).

Project timeline: Estimated completion in summer 2019

Chelsea project

Chelsea custom home concept drawing by EkoBuiltThis Quebec property is located within Quartier Meredith Subdivision, a brand new subdivision located 20 minutes from downtown Ottawa. The community is a highly sought after one because of its convenience to the capital. Chelsea is also a nature/outdoor lover’s paradise as it borders Gatineau Park.

The design is a modified version of our Fiddlehead model with an attached garage and a basement.

Project timeline: Construction to begin May 2019 with completion in December 2019

Old Chelsea project

Old Chelsea custom home floorplan by EkoBuilt

The open floorplan has a clever L-shape that accommodates bedrooms and tucks a screened in porch off the kitchen for warm weather dining.

Yet another Quebec-side property, this one is located near the Gatineau River in a peaceful rural section of Old Chelsea with abundant trees.

The design is a custom client inspired concept. Inspiration has been taken from the client’s beautiful property which is surrounded by white pines. A minimalistic approach to design has resulted in a three-bedroom home with a smaller footprint that still maintains comfortable spaces for the homeowners.

Project timeline: Construction to begin May 2019 with completion in December 2019

Perth Townhome project

Perth town homes for saleIf you’ve been following EkoBuilt in recent months, you’ll know about this five-unit property that we’re developing near Perth Fairgrounds in a sustainable town inspired community.

The design is an EkoBuilt inspired concept:  a modern, multi-unit mini-community with a net-zero footprint. It is the first of its kind in Perth, Ontario.

Project timeline: Construction to begin May 2019 with completion of December 2019

Round Lake project

Floorplan for custom summer home in Round Lake

Click to enlarge the working floorplan; a second version with cupboard space in the bedrooms also exists.

This Ontario property is located near Pembroke on the north east shore of beautiful Round Lake.

The design is a custom client inspired vision of a summer camp with modern design and appeal. We all know modern design starts with building passive!

The lakefront orientation is perfect for this project, with living areas facing the waterfront which is also due south, a fundamental principle in passive house design.

Project timeline: Construction to begin May 2019 with completion of December 2019

Frontenac project

Shared family home custom design by EkoBuiltThis property is located near Cloyne village in North Frontenac Township, Ontario, south of Bon Echo Provincial Park.

This home design is a custom client inspired concept developed by two families coming together to save on cost. The home two-family home contains individual suites with a shared entry, kitchen, loft/games area and a great room. See the floorplan below for the main level.
