Results and Resources

The Green Building Research Laboratory houses extensive facilities for both fundamental research and applied measurements in support of the green building industry (see facilities page). The GBRL also creates and disseminates reports and software for use in green building research and practice. This page will host these resources and provide links as appropriate to external sources for useful information on selected topics.

A Green Roof Energy Calculator has been developed for the USGBC. See CALCULATOR

In a prior study (~2003-2005) for the US EPA we created the Urban Heat Island Mitigation Impact Screening Tool -- MIST. We are in the early stages of planning an update to this tool which will better integrate regional (mesoscale) and neighborhood/canopy scale phenomena (stay tuned). The original MIST tool has been taken off-line (July 2014) since the assumptions and modeling methods were outdated. We remain optimistic that we will secure the necessary resources in the near future to create and publish MIST 2.0.



Urban morphology and surface properties play an important role in the formation of the urban heat island. This time-lapse image of downtown Portland illustrates the diurnal evolution of building envelope surface temperatures.
