Labs & equipment

Our facilities enable researchers and industry leaders to develop cost-effective, net-zero energy buildings that produce as much energy as they use.


Solar simulator - environmental chamber (SSEC) facility
Solar Simulator - Environmental Chamber (SSEC)

The Solar Simulator - Environmental Chamber laboratory is an internationally unique facility developed with a $4.6 M grant from the Knowledge and Infrastructure Program (KIP). It enables accurate and repeatable testing of solar systems and advanced building envelopes under standard test conditions with full simulated sun and indoor plus outdoor conditions. It consists of two major systems:

  • A large scale solar simulator is designed to reproduce natural sunlight in order to test various solar systems such as photovoltaic modules, photovoltaic/thermal modules such as the JMSB solar system, solar air collectors, solar water collectors and a range of building-integrated solar systems.
  • Specific capabilities of solar simulator (testing at room conditions)
  • Consists of 8 special metal halide (MHG) lamps with an artificial sky to remove infrared radiation from lamps (lamps individually controlled and dimmable); meets the specifications of the relevant standards EN 12975:2006 and ISO 9806-1:1994.
  • Collimation: approximately 80% of the emitted radiation lies in the range in which the incidence angle modifier of a regular flat plate collector varies by no more than 2%
  • Test specimen size: up to 2.4 m x 3.2 m
  • Less than ± 10% homogeneity, under 1-sun (depending on test specimen size)
  • Customized solar air collector testing platform (able to test systems such as the JMSB BIPV/T system)

Specific capabilities of environmental chamber

  • Test wall systems and rooms up  to 3 m wide x 7 m high, for hygrothermal and energy performance, including solar electricity and useful heat generation
  • Temperature test range: -40° to 50°C , under specific conditions
  • Temperature stability can be maintained within 1°C
  • Relative humidity range between 20% – 95% (depends on temperature)
  • Specially designed windows that allow through sunlight produced by a 6-lamp mobile solar simulator

Solar Energy / Lighting Lab & Solar House

250px-TestRoom2

A variety of equipment has been acquired, including solar and lighting instruments, particle image velocimetry system, heat flow meters. Our lab also includes an artificial sky (3 x 3 x 3 m) facility. The main tests being performed in this lab consist of testing of motorized shading devices in conjunction with dimmable lighting. Industry partners include Philips and Unicel Architectural.

Boundary-layer wind tunnel
Boundary-layer wind tunnel

The effect of wind on building models is reproduced in a boundary layer wind tunnel. This allows for the measurement of mean and fluctuating wind loads on buildings, air flow around tall buildings and around groups of tall buildings, environmental pedestrian level wind studies, and effluent dispersion (contamination of buildings by smoke and building exhaust from stacks). Computational evaluation of wind effects on buildings is also carried out.

Water flume

A closed-circuit channel (3.0m long and 0.75m wide) is used to visualize the flow around buildings and to investigate snow drifting / accumulation problems associated with buildings.


Energy Efficiency Laboratory (EV-16.301)
Energy efficiency laboratory

The Energy Efficiency Laboratory houses an Environmental Chamber with a controlled thermal environment used for different studies related to energy efficiency in buildings, reduced scale air infiltration through walls and rotating doors, thermal comfort and displacement ventilation.
