| Renewable energy systems offer heat
and power without any greenhouse gas emissions. As the cost
of renewable systems decreases, solar water heating, solar
air heating, photovoltaic, and wind energy systems are becoming
an accepted alternative to meet building energy needs. Enermodal
has design and construction experience with all of these
technologies. Enermodal has 25 years of experience in
designing solar water systems. Solar systems have been used
to heat indoor and outdoor swimming pools, car washes, laundry
facilities and shower water in workplaces. Enermodal managed
two large-scale field trials of residential solar domestic
hot water systems, conducting field inspections, performance
monitoring and homeowner surveys.
Enermodal Engineering is actively involved in the design
and implementation of Canada's first solar community in
Okotoks, Alberta:
Drake Landing
Solar Community. Ninety percent of the space and
water heating needs of 52 single-detached homes will be
met with solar thermal energy. Enermodal Engineering produced
the project feasibility study; provided design engineering,
construction supervision and commissioning services for
the major systems; headed up the simulation team predicting
the long-term viability of the entire system; and is one
of the leads for the monitoring effort to verify system
performance over the coming years. This project was winner
of the Climate Change category at the Alberta Emerald Awards;
it also won the Best Solar Thermal Project of the Year from
the Canadian Solar Industries Association.
Solar ventilation air heating is one of the most cost
effective applications of renewable energy. Enermodal has
designed and monitored the performance of a dozen industrial
systems, including a Solarwall for pre-heating ventilation
air (Steelcare, Hamilton, Ontario). We developed
simulation
tools (RETScreen and SWIFT) to predict the performance
of solar air systems. Currently, Enermodal is conducting
field trials of solar crop drying systems in Panama, Costa
Rica, China and India. Enermodal, working with local partners,
is installing, commissioning and monitoring the systems
to show that solar is the best option for crop drying.
The cost of photovoltaics has fallen by ten-fold over
the past few years, and now the cost of these systems is
approaching that of grid power. Photovoltaics can be used
in stand-alone systems to power remote applications, or
can be building-integrated systems with connection to the
grid. Enermodal has designed both system types and negotiated
power purchase agreements with electric utilities.
Depending on the site and system size, wind power can
be a viable option to produce electricity. Enermodal has
designed several wind power systems including systems in
northern Canada where weather and geographic isolation present
special challenges.
