Influence of plant coverage on the total green roof energy balance and building energy consumption

Posted April 4th 2016

Major Findings: Implementation of our green roof model into EnergyPlus showed importance of the plant coverage rate for the total daily received radiative flux. Specifically, the radiative flux is reduced by 32% when comparing the bare soil and fully covered green roofs. Importantly, our model enables building energy consumption calculations with the radiative flux depending on the coverage rate in actual green roofs.

Variability of optimal solutions for building components based on comprehensive life cycle cost analysis

Posted November 3rd 2015

Major Findings: This study surveyed close to one hundred building systems designers in the U.S., and compared their responses to building energy simulations and life cycle costs assessment (LCA). The comparison indicates that surveyed designers underestimated the influence of wall assemblies, and overestimated the influence of window properties on the life cycle cost. More wide-spread use of LCA analyses could potentially address these biases.

"Different modeling strategies of infiltration rates for an office building to improve accuracy of building energy simulations"Calculations of time-dependent infiltration rates can improve accuracy of energy simulations, especially for climates with wind velocities persistently above 10 mph (4.5 m/s). Accurate assessment of infiltration rates is still a challenge for commercial buildings. The use of multi-zone models with a good database of typical leakage rates for different enclosure openings is probably the best approach at present.

"Effect of Urban Neighborhoods on the Performance of Building Cooling Systems"
Major Findings: For studied packaged window and rooftop units, COP decreases by several to more than ten percent when the urban density increases from rural to densely-built urban neighborhoods. This COP decrease is due to the increase in local temperatures, and the COP degradation would hold for other types of heat rejection equipment rendering its performance less efficient in dense urban neighborhoods.

We found this article published in 1986 as the first journal paper of the current interim president of the University of Oregon, Dr. Scott Coltrane, fascinating. The paper findings are still highly relevant as they outline best practices and principles for engagement of building occupants in energy saving initiatives.
