The purpose of
this report is to provide General Committee with budget and design details for
all proposed and recommended solar PV panel systems at the Civic Centre, as per
the Resolution of Council Meeting No. 18 dated
Resolution of
Council Meeting No. 18 dated
Staff requested
and received proposals to install a PV panel system on the Civic Centre
roof. Several locations have been
analyzed and proposed. While a number of
locations could be chosen to install the panels, the Great Hall roof, second
floor south balcony (south wing) and the roof of penthouse mechanical rooms
were considered as best candidates to accommodate these panels. Among these three locations, the roof area on
Great Hall Entrance has been found to be inappropriate due to shading and
excessive cost to accommodate the panels.
The second floor balcony would pose a concern as this balcony is being
used as an emergency fire exit walkway.
The most cost effective location that offers maximum visibility and more
energy production would be the roofs and south walls of the penthouse
mechanical rooms (Location Option 3), as shown on the following picture.
Installation of solar PV panels on the penthouse mechanical room roofs and walls would offer lowest cost, as proposed by Dasd Contracting Inc. amounting to $98,500. There may be a contingency required for this type of work, hence an allowance of $14,775 has been made.
The exact rating of the panels would be 9.6 kW. This system would use 48 Canadian Solar 200 watt panels and 2 inverters with combined maximum output of 12.5kW (nominal output 10 kW). The panels will be mounted at the recommended location as shown in Appendix A. Sunlight falling onto these panels will be converted to electricity. This electricity would then be fed into the buildings electrical system. Any excess electricity over what is required by the Civic Centre would be supplied to the hydro grid. However, the likelihood of this happening is extremely low due to the low capacity of the panels.
This system would have a better financial payback than indicated in
the previous Council Report dated

* Two (2) bidders did not supply the
mandatory agreement to bond as outlined within the bid document and therefore,
these bidders were non-complaint and as such were disqualified.
After bid opening of RFP 190-R-09 and review
of financial cost which far exceeded budgetary requirements for this
project. Staff released post bid
addendum # 1 to the four (4) bidders who submitted a proposal. The original submissions were based on a
fixed location on top of the Civic Centre that proofed not to be cost effective.
Therefore, staff issued post bid addendum # 1 that deleted the fixed roof
location and allowed alternate locations that would provide more panels and a potential to increase sun exposure to increase
efficiency.
The evaluation team was comprised of staff

This project would support “Building Markham’s Future Together”
goals and in particular is well aligned to the “Environment” area of strategic
focus. In addition, it would complement
the efforts and commitment to the
Sustainability Office
