Research and Development Project: The Calibration of Bilan Carbone® for Ontario, Québec and British Columbia


Objective

The object of this project was to adapt and improve on the French tool, Bilan Carbone® (developed by the French Environment and Energy Management Agency/ADEME), for the Canadian region. The success of Bilan Carbone® in Europe provided us with best practices in initiating positive work by municipalities and organizations in climate change mitigation. Initially the focus was on the provinces of Ontario, Québec and British Columbia, but the intention is to over time, expand the scope to include the other provinces and territories of Canada. The calibration of Bilan Carbone® required an evaluation of the emission factors and revising them to be appropriate for the Canadian environment. The results of the work will be Encompass, the tool, methodology and training course that will be distributed in Canada by Internat Energy Solutions Canada.

Methodology

One of the advantages of Bilan Carbone® as a GHG emissions accounting tool is that it is extremely comprehensive and contains life cycle emission factors for a range of processes, services and products including:

  • Electricity
  • Propane
  • Diesel
  • Gasoline
  • Natural Gas
  • Air conditioning
  • Waste (landfill and recycling)
  • Paper use
  • Transportation (automobile, public transit, air)
  • External services (banking, consultants, post, internet etc.)
  • Office supplies
  • Assets (vehicles, furniture, IT assets)

The adaptation of Bilan Carbone® for the Canadian environment required extensive research, calculations and document analysis. Contact was made with a number of public and private organizations to gather the necessary information that is not readily available. A life cycle approach was taken which required an analysis of both upstream and downstream energy usage. Climate change policy was also researched and used to develop forecasting capabilities within the tool.

Research and Development Project: The Design of a Multifunctional Building-Integrated Photovoltaic (BIPV) System


Objective

Canada's buildings have an enormous impact on the country's energy demand and environmental impact, accounting for almost one third of the total energy use, half of the electricity usage and a significant share of the greenhouse gas emissions. This effect is only increasing with the rapid development of commercial and residential high-rise buildings in Canadian cities. These buildings are increasingly using thermally inefficient glass façades that can often provide excessive natural lighting for much of the day. As a result, federal and certain provincial governments are establishing building codes with stricter energy performance requirements for buildings.

This project's objective is to develop and commercialize a multifunctional building-integrated photovoltaic (BIPV) glazing design as a more energy efficient substitute for standard glazing in new building construction or as a retrofit of existing structures. The BIPV glass panel will minimize heat transfer to the external environment when not desired, block undesired solar gains (but still transmit visible light) and finally produce an electrical load that can be used within the building. The project will build on the successful design and deployment of an initial BIPV project completed in 2011. IESC's BIPV product will help building developers not only meet, but exceed building code regulations, significantly reduce energy demands, improve occupant comfort and generate clean solar electricity.

Action Plan

In order to successfully complete this project, IESC will be performing five important actions as part of the research and design stage:

  1. Energy models will be constructed to determine the energy load reduction and electricity generation resulting from the implementation of the BIPV glazing product in multi-storey buildings. EnergyPlus will be used to model typical multi storey buildings with and without BIPV glazing to calculate the heating and cooling energy savings. A solar energy modeling tool will be used to simulate the performance of the solar cells in the BIPV.
  2. The prototype BIPV panels are to be thoroughly tested to obtain real performance parameters for the glass and solar cells with the data then fed back into the energy models. IESC will be retrieving data from its prototype BIPV system installation on the Toronto Harbourfront Centre Enwave Theatre. Also, as a member of the NSERC Smart Net-zero Energy Buildings strategic Research Network (SNEBRN), IESC will be collaborating with researchers to have the BIPV glass panels tested and characterized using advanced glass and solar module testing equipment.
  3. The building energy models will then be used to perform a financial study in order to determine the value added of the BIPV glass product as a glazing substitute. Return on investment (ROI) and payback period calculations incorporating scenario analyses will be completed to determine the price point on a per unit area basis at which the BIPV product would be in high demand with building developers.
  4. IESC will meet with building developers and managers to gauge product interest and receive feedback. A study on the current and future market for BIPV in North America with targeted weather conditions for the short, medium and long term will be estimated.
