Achieving Net Zero: Renewable Energy Options to Get You There

November 29, 2017
Location: BILD Office, 20 Upjohn Rd, Suite 100, North York, ON
Instructors: Svend De Bruyn and Erik Janssen

Course Description

Join Toronto and Region Conservation’s resident technical experts for this informative one day training course. This course is intended for builders who are interested in learning about renewable energy options that can be utilized in the residential housing market and the mechanical systems that work in tandem to achieve net zero.

The installation of photovoltaic (PV) systems in Ontario is under the purview of the electrical trades, and within that trade, there are electrical contractors trained specifically for the design and installation of residential roof top PV systems. This workshop is intended to educate residential builders and to provide them with a basic level of understanding of the ins and outs of PV systems: their components, installation considerations, procuring contractors, cost vs payback, etc.

Harvesting sunlight and converting it to electrical energy is only the first half of the energy equation needed to a meet a net zero home’s energy requirements. Strategies to leverage the harvested solar energy must be used to optimize mechanical system performance leading to significant load reductions. Case studies performed by TRCA staff will be used to highlight the performance of these systems.

At the end of this workshop builders will have the appropriate knowledge and information to make informed decisions with respect to constructing any solar-ready, or solar installed projects and will be better informed as to the selection of optimal mechanical equipment.

Topics to be discussed include:

•  Electrical grid connection topology: feed-In-Tariff, net metering, self-consumption, backup power
•  Photovoltaic system technology: modules, inverters, batteries, charge controllers, monitoring, BOS
•  Installation considerations: safety, racking, solar ready trusses, flashing, battery location, visual impact
•  Administration: power procurement contracts, line impact assessments, LDC connection agreement, ESA inspection, disconnect/reconnect, warranties (system, yield and equipment)
•  Economics: installation cost, yield, payback, time of use vs tiered billing, recurring costs (reroofing, inverters, modules), RET screen modeling
•  Qualifying contractors: CanSIA, CSA certification, ESA electrical contractor
•  Qualifying materials: CSA, UL, ETL, trusses, flashing

Mechanical Systems
•  Heat pump basics: types of heat pumps ,performance rating labels, rated conditions compared to actual operating conditions, comparison of heat pump ratings to conventional equipment ratings
•  Ground source heat pumps: a comparison of horizontal and vertical loops and the use of desuperheaters are also covered, sizing considerations,
•  Air source heat pumps: variable capacity all climate air source heat pumps, air to air, air to water, various systems topologies including, mini-splits with sizing considerations
•  Air source water heaters: types and performance w installation considerations
•  Solar hot water systems: compared to PV / Air source water heaters,
•  Hybrid energy systems: gas appliances used in combination with heat pumps
•  Energy distribution systems: Forced air, Hydronic, Hybrid, Zoning


Who Should Attend?

This workshop is intended for builders, contractors, architects, project managers, developers, realtors, consultants, technologists and all those responsible for building high performance homes.
