Canadian project

Context
In 2008, the Canadian total end use demand was of approximately 11 000 PJ, of which the residential sector, with more than 8 million detached residential houses, represented about 14%. Heating accounted for over 50% of this home annual energy consumption. In the province of Québec (Eastern Canada), more than 75% of new houses use electrical baseboards as heating systems. Because each of these houses consume in average 26 700 kWh per year, still a significant component of the total energy demand, reducing it presents a major challenge in the future. By using a variety of conventional and new technologies, future energy efficient houses must substantially reduce the space and hot water heating consumption.
During the past decades, the Canadian Federal Government, as well as almost all Provincial Governments, undertook several initiatives aimed at reducing the amount of home energy consumption. Some of these initiatives, as R2000 (note: a similar initiative, called Novoclimat, has been developed in the province of Québec) and Energy Star programs, aided by financial incentives, supported the development of high energy efficient technologies, as heat pumps and other heat recovery and/or renewable energy-based systems. As a result, new housing recently built is on average 13% more efficient in space and hot water heating than those built twenty years ago.

Canada's contributions
First, the Canadian project will provide an overview of heating and cooling concepts for new Nearly Zero Energy Houses integrating heat pumps, already in-field implemented and tested, or currently in a development and/or design process (Task 1).
Second, the most promising concepts able to be successfully implemented in the future in the Canadian Nearly Zero Energy Houses, will be analysed, optimized and improved at the level of the global system integration with renewable energies (geothermal, ambient air, solar direct and/or building integrated photovoltaic, wind), house waste heat recovery, and overall control sequences (Task 2).
A techno-economic analysis of the integration of HPs and renewable systems to houses of three construction vintages will be presented, including (i) a typical existing home (1980s), (ii) a typical newly constructed home, and (iii) a highly efficient low energy home. Some analyses of HPs integrated with cogeneration units and renewable systems will be presented as well. This approach will also be applied to commercial and multi-unit residential buildings. To date, archetype models of large office and multi-unit residential buildings have been developed to examine the implications of using heat pump systems on a larger scale and identify potential savings from scale economies.
Third, laboratory- and in-field-scale heating and cooling systems for Nearly Zero Energy Houses will be presented. They will include, for example, multi-function direct expansion or indirect ground-source heat pumps for alternate or simultaneous space heating and domestic hot water production, long-term design validation/behaviour of ground-coupled heat exchangers operating in the Canadian cold climate, etc. The main thermodynamic parameters will be determined and the simultaneous performance factors in both heating and cooling modes, evaluated. Improvements of standard heat pumps available on the market, aiming at increasing their efficiency when applied in Nearly Zero Energy Houses, will be also proposed. Share of the house and its main HVAC components annual seasonal and energy consumptions will be determined and compared with those of standard Canadian houses (Task 3).

Deliverables
Intermediate and final reports, including optimized design and system layouts, modeling and simulation results, when available, laboratory and in-field experimental parameters and seasonal energy performances, and some best practice cases, will be provided.

EQuilibriumTMHousing Initiative of the
Canada Mortgage and housing corporation

EQuilibriumTM is a national sustainable housing
demonstration initiative, led by Canada Mortgage
and Housing Corporation (CMHC). that brings the
private and public sectors together to develop
homes, and eventually communities that address
occupant health and comfort, energy efficiency,
renewable energy production, resource
conservation, reduced environmental impact and
affordability.

NSERC Smart Net Zero Energy Buildings
Strategic Research Network 

SNEBRN is currently the major Canadian
research effort in smart net-zero energy
buildings. It brings together 29 Canadian
researchers from 15 universities to develop the
smart net-zero energy homes and commercial
buildings of the future. The Network also
includes researchers and experts from Natural
Resources Canada (NRCan) and Hydro-Québec.
Industrial partners from the energy and
construction sectors are involved in most
projects, developing the know-how that will
help them compete in the global market.
