Thanks to Drs. Gail Pool and Frances Stewart for hosting us at their lovely Berlin Vernacular home on Sunday December 6, 2015.  It was a real treat to hear, first hand, how they have carefully researched and restored this two-story house, reminiscent of the Queen Anne style of architecture.  An inspiring and most enjoyable afternoon!

Play On: Sports Past, Present, and Future


As the lazy days of summer quickly draw to a close, thoughts begin to turn to the fall and the various community activities that mark the annual changing of the seasons.   From an architectural and heritage perspective, the most significant of such is DOORS OPEN WATERLOO REGION. This free annual showcase highlights interesting places and heritage sites throughout Waterloo Region, many of which are not regularly open to the public.

This year’s Doors Open – the 12th annual for our community – occurs on Saturday, September 19th, 2015 and runs from 10:00 AM until 5:00 PM. In 2015, Doors Open events across Ontario are celebrating sports. Community clubs, legendary venues, professional teams, and innovative facilities will be the focus at 10 sport-themed sites here in Waterloo Region. Another 30 sites (40 in total) of cultural and heritage interest will also be open to the public, including the former Waterloo County Court House wherein the North Waterloo Region Branch of the ACO will be staffing a display. Built in 1964 and renovated in 2014/15, this unique facility, originally designed by Snider, Huget, and March Architects and Engineers, is a notable example of modern architecture. Many will recall the insightful presentation that was delivered by Professor Rick Haldenby, former Director of the UW School of Architecture, on the subject of modern architecture at our 2015 Annual General Meeting.

While DOORS OPEN WATERLOO REGION is fortunate to benefit from a number of sponsors and partners, volunteers are still required to help set-up and staff displays. Accordingly, we would kindly welcome the volunteer contributions of any members available on the 19th. Whether you just have an hour of free time, or could participate for the entire day, we would greatly appreciate your assistance.

For more information on DOORS OPEN WATERLOO REGION please see: http://www.doorsopenontario.on.ca/Events/Waterloo-Region.aspx.

To volunteer at the ACO-NWRB display or for further information, please contact one of the following two Executive Committee members:

Fate of Sacred Heart Convent hangs in the balance April 13

Sacred Heart Convent, 79 Moore Avenue, KitchenerThe fate of the Sacred Heart Convent at Shanley and Moore Streets, Kitchener  hangs in the balance Monday night, April 13, 2015.


Kitchener Council will decide whether or not to save it from demolition, by designating it as being of cultural heritage value and interest.

The Roman Catholic Hamilton Diocese wants to demolish the building to reduce its building maintenance costs and create a 20-space parking lot.

Kitchener Heritage Planners contacted the Region of Waterloo Director of Housing to see if there was interest in adaptively re-using the convent as affordable housing.  The Region’s favourable and encouraging response was passed on to the Diocese, but the Diocese has refused to withdraw the application for demolition.

Unless Kitchener City Council moves to designate  Sacred Heart church buildings on the property, the Diocese will be legally entitled to demolish the building on May 8, 2015.

  Monday night’s council meeting is important

7 p.m., Kitchener City Hall, 200 King Street West, Kitchener


There are several ways you can help.

  • Come to Kitchener Council on Monday night and speak in favour of designating the Sacred Heart Church buildings – convent, rectory, former pastor house, residential building and the church itself. Email Rita Delaney or come to City Hall by 6:45 p.m.
  • Share some stories or facts that support its
  • physical or design value —  g. representative of a particular style, material or construction method; displays a high degree of craftsmanship or artistic merit.  The convent was designed by architect John Macleod Watt, author of over 60 large/public buildings, from Windsor’s Church of the Ascension to London’s McCormick Biscuit Factory to Kitchener’s St. Mary’s Hospital.
  • historical or associative value — e.g. direct associations with a belief, activity, organization or institution that is significant to the community;  yields information that contributes to the understanding of a community; demonstrates the work of a particular architect or builder, e.g. information about the importance of Sacred Heart Church to the Polish community.
  • contextual value — e.g. Is important in defining, maintaining or supporting the character of an area; is physically, functionally, visually or historically linked to its surroundings; is a landmark.
  • Email the Kitchener Mayor and Councillors about your concerns.

Reduce Emissions: stop demolishing heritage buildings – adapt, retrofit and reuse them instead

Figure 4 of Ontario’s Climate Change Discussion Paper shows that the waste, transportation and building sectors  all showed increased emissions.  To stop this, ACO North Waterloo Region believes that Ontario’s climate change strategy should include measures which recognize the very positive environmental impact of conserving and retrofitting heritage buildings.

We strongly advocate that measures be taken to stop demolishing heritage buildings — adapt, retrofit and reuse them instead.

 There is strong evidence to show this will reduce emissions.

chart showing number of years it takes for a new energy efficient building to overcome the negative environmental impacts of construction and demolition of the heritage building it replaced

A 2012 study by the Preservation Green Lab of Washington’s National Trust for Historic Preservation showed that if old (heritage) buildings were demolished and replaced with new buildings, even highly energy efficient buildings, it would take between 10 and 80 years for the environmental assaults suffered in the new construction to be overcome by the higher operating efficiency of the new  buildings.[1]

The study looked at seven different building types, including commercial offices, single and multi-family homes, urban village mixed use, schools, and warehouse conversions.  It did Life Cycle Analyses of the emissions and other environmental impacts of retrofitting an existing heritage building  vs. building a new building of the same dimensions.  It did this in four climate areas: Chicago, Portland, Atlanta and Phoenix, a total of 28 different comparative studies.

Considering Ontario’s 2020 target date, and leaving aside conversions of warehouses to luxury living spaces, there was not a single case where it’s better for our climate and environment to replace old buildings with new, highly energy-efficient ones of a similar size.

The negative climate change effects come from the impacts of demolition (e.g. energy to destroy and truck to landfills) and from the manufacture and transportation of replacement raw materials and building components.

So, we need measures which discourage the demolition of heritage buildings:

  1. require Life Cycle Assessments to be part of all new construction proposals;
  2. require proof that demolition is necessary (reversing the current assumption that older and vacant buildings should be destroyed, where the onus is on heritage advocates to prove such buildings should be kept);
  3. prohibit property tax reduction for vacant premises;
  4. introduce a special Carbon Demolition Tax: a tipping fee at landfills that puts a high surcharge on waste materials from demolitions where there is no plan to replace the destroyed building with a structure that is demonstrably more energy efficient (this might slow down the demo of serviceable structures where the lot is then left empty);
  5. require recycling of building materials – bricks, timber, glass.
