The diagram below depicts some of the green roofs scattered across the MetroVerde nursery and urban farm.
|Green Roof Temperature Monitoring Locations|
Location D is a the decking under a south facing sloped asphalt shingle roof exposed to full sun during the day. Location C is the decking under a 3" extensive vegetated roof, south facing as is D and exposed to full sun. These two face the most brutal of solar gain conditions.
Other locations include F, a north facing sloped green roof, and G the underside of a 2" extensive green roof on the feed storage shed (flat roof and under partial shade).
The below temperatures were taken at random times. We will implement a standard routine and include Celsius values soon.
At first glance it appears the decking temperatures under the green roof follow the outside air temperatures, moderated significantly from the temperatures shown on from the decking under the exposed asphalt shingles. More data soon, and we will set up the temperature spreadsheet as a separate page on the blog here.
