Architectural engineering focuses on the design, construction and operation of buildings and the integration of their systems. The department offers Master of Science (MS) and Doctor of Philosophy (PhD) degrees in architectural engineering with a study emphasis (i.e., focus area) in:

  • Building energy engineering
  • Illumination engineering
  • Materials and carbon
  • Construction engineering and management

Graduate studies in architectural engineering are offered through the Department of Civil, Environmental and Architectural Engineering. The Graduate Record Examination (GRE), consisting of the aptitude tests and advanced test in engineering, is used to evaluate MS and PhD candidates. Candidates who submit GRE scores are more likely considered for financial assistance.

Course code for this program is AREN.

Research Interests and Facilities

The Larson HVAC Laboratory has been a staple of the University of Colorado's building energy research activities and AREN program education. The laboratory has been the stepping stone for fundamental and applied research in building energy efficiency, energy controls, thermal comfort and indoor air quality. The newly renovated Larson HVAC Laboratory provides a unique facility that permits the evaluation of entire systems in a controlled dynamic environment, providing repeatable test conditions. The laboratory has been recently redesigned to allow maximum flexibility in conducting a wide variety of research and testing procedures. In particular, both the HVAC and control systems in the laboratory are reconfigurable in that components, subsystems or entire systems can be readily installed and tested. For instance, the performance of air handling units, displacement ventilation units, chilled beams and variable refrigerant flow units can be tested. In addition, coils, air mixers, dampers, filters and variable frequency drives can be evaluated. Moreover, the laboratory offers the possibility to test standalone HVAC and refrigeration systems including water heaters, boilers, thermal energy storage tanks and chillers.

The Lighting Laboratory is a learning and research space for lighting students in the AREN program. The lab has a dynamic ceiling with adjustable height to allow a wide range of academic and research exploration. Although the lab has a full-wall, with north-facing windows, there are blackout curtains installed to eliminate any undesirable external light. In addition, this lab houses a goniophotometer used to measure the intensity of light leaving a luminaire at various vertical and horizontal angles. The measured data allow establishing photometric light distribution of the luminaire and metrics such as total lumen output, luminaire luminance and zonal lumen summary. The lab also houses a small lighting sphere, which allows testing of lumen output of LED luminaires and LED chips. In addition, the lighting lab includes a studio space used primarily for lighting research. The lab has an extensive aluminum open ceiling grid that allows for quick electrical and physical connection of light sources and luminaires for research. For lighting design-oriented classes, students have access to theatrical-type and programmable color-changing luminaires to do mock-ups and study lighting effects.

The AREN laboratories offer state-of-the-art facilities to test a wide range of operational and control strategies for lighting and HVAC systems and subsystems. Indeed, several control projects have been carried out in the Larson HVAC laboratory including demand-ventilation controls, optimal chiller and thermal energy storage controls, outdoor air intake controls, and optimal operation of evaporative systems. In addition, fault diagnostic algorithms have been tested in the laboratory for specific HVAC equipment including for heating and cooling coils, chillers and outdoor air intake dampers.
