The City College of New York - New York, NY

Contact: Nicholas Madamopulos

The City College of New York (CCNY), founded in 1847, is a flagship college of The City University of New York (CUNY) system. CCNY is a comprehensive teaching, research, and service institution dedicated to accessibility and excellence in undergraduate and graduate education. CCNY offers a wide range of degrees related to engineering, architecture and science with focus on energy, sustainability and the environment. The Grove School of Engineering is active in Research and Training of graduate and undergraduate students. The Grove School of Engineering and The Bernard and Anne Spitzer School of Architecture offer a graduate program in "Sustainability in the Urban Environment"?. The program offers an interdisciplinary MS in Sustainability with two concentrations: an Architecture concentration suitable for students with backgrounds in architecture; and an Engineering-Science concentration appropriate for engineering or science majors. The overall aim of the program is to develop a workforce with the knowledge and skills that 21st century workplaces will increasingly demand, i.e., to enable them to be innovative and flexible contributors to sustainability solutions.

As New York City's only public university, CUNY has a special role to play in helping to meet the city's needs. The Building Performance Lab-CUNY, is ideally positioned and equipped to serve as a catalyst for change. Through collaborations with other parties, the BP lab works to accelerate market transformation in the buildings sector. The Lab's multi-track approach also includes stimulating applied research, promoting technology transfer, and conducting outreach to the real estate sector to raise awareness of sustainability goals and how they can be achieved. One focus of our work is greening existing commercial properties by promoting advanced building system technologies and best practices that reduce energy use and improve indoor environmental conditions and waste management practices. Greater tenant satisfaction is one result.A crucial best practice is the monitoring and verification that ensure that, once achieved, optimum building performance is maintained. Another focus of our work is long-term workforce development, which we pursue through curriculum development, internships, and other technology training.

The University of Colorado - Boulder, CO

Contact: Gregor P. Henze, Ph.D., P.E.

Architectural engineering is a long-established engineering degree program in the College of Engineering and Applied Science at the University of Colorado Boulder: Architectural engineering was established in 1925, awarded its first degree in 1929, and has been continuously accredited since 1936, along with dedicated graduate degree programs. Our CEAE department is ranked 20th overall and 14th among public graduate programs in 141 universities surveyed by U.S. News and World Report. The National Research Council gave the department an overall ranking of 7 in the civil engineering field, and in the top 5% of research doctorate programs in the nation. Moreover, the University of Colorado is ranked 25th among US universities and 34th in the Shanghai ranking of the world's best 500 universities.

The University of Colorado offers BS, MS, and PhD in architectural engineering. While the architectural engineering graduate degrees have only be offered since 2012, the Building Systems Engineering group has been producing MS and PhD graduates through the CEAE department for over 30 years. Graduates from the program work in both the public and private sectors in the broad areas of building energy systems, including academic positions at universities around the world, researchers at national laboratories, and designers and analysis in the building industry.

At the graduate level, the Building System Engineering group seeks to improve the sustainability and effectiveness of buildings. Research areas include the design, modeling, and analysis of integrated building energy systems, renewable energy technologies, sustainable materials for buildings, indoor environmental quality, grid-integration and model predictive control for building energy systems, and innovative HVAC and illumination technologies. The program includes seven faculty members with backgrounds in mechanical engineering, architecture, illumination engineering, sustainable materials, acoustics and renewable energy engineering. We offer three degree specializations align within our research area: Sustainable building design and operation, renewable energy systems for buildings, and illumination engineering.

Training in OpenStudio and EnergyPlus is provided in the context of graduate classes on building energy simulation and sustainable building design.
