The Residence -
Before and After:
An Energy Efficiency Marvel
Undertaking a heritage renovation of any building is often a daunting task and a church brings with it unique challenges, as did this one. While the open space (see pictures just below) appears to have limitless possibilities, the fact is that the overall structural assembly can limit the addition of internal walls and design upgrades. Further, careful attention to the stone foundation is necessary, as this may dictate the location of partitions within the space.
We began our journey to see this happen right here in Lanark, Ontarioin May of 2013 with a full foundation survey, having noted on the initial inspection that one corner of the building required some stabilization, which was completed by a spread footing. There is a center stone wall within the foundation, reducing the floor joist span. This worked to our benefit as the interior was designed, including the installation of the custom built timber frame loft.
Before renovations started, looking west, with the alter, cross and furnishings in place.
Looking east. Note that the windows, lights and some of the wainscotting remain.
The building was energy audited before renovations began. The blower door test established that the heating costs, using the existing oil furnace, would be just under $10,000.00 annually.
This result substantially dictated the design decisions, which were to come. Renovations went forward with the construction of an entire interior wall, including on the angled ceiling; 25% reclaimed metal studs, fitted with Roxul insulation; (see pics below) and a 6 mil air barrier, along with dozens of cans of spray foam were used to fill every accessible void in the walls. The partial attic was accessed and filled with recycled fiberglass insulation. To act as an air barrier, the exposed ceiling was sprayed with XIM seal coating. The entire crawl space was spray foamed and its floor was covered in plastic and roll foam insulation.
Once the walls were completed, locally supplied solid pine tongue and groove paneling was added to the walls, (see below)making a warm, inviting interior when coupled with the timber frame loft, which contains the master bedroom, 4 pc bath and three closets.
Custom made Krypton gas windows (above) were fitted inside, so that the original stain glass windows remained as a third window for energy value. The spiral staircase (below) was re-purposed from a home in Wiarton Ontario and upgraded with extra spindles. The loft railings were custom built.
Once renovations were complete, Verk Consulting returned to retest the space. The home is now an EnerGuide rated 84 home with a heating cost of around $700.00, annually, down from the original estimate of $10,000. Verk Consulting stated in their final report that this home was the tightest building they had tested in 10 years. The church contains a 95.1% high efficiency wall boiler, which provides the hydronic air handler heat, and all of the hot water in one unit. This installation can be Internet controlled from anywhere in the world. An Energy Star mini-split A/C & heat pump with a 12,000 BTU capacity, well under the recommended size, was installed to function as air conditioning only. It works perfectly during the heat of the summer to cool this amazing church. The much reduced annual heating cost and the ease of cooling are testaments to the energy values of this home.
