From "Amended Toronto Green Building Standards Retain Bird-Friendly Measures" (November 2009)
"Council left intact existing green standard measures aimed at preventing bird-building collisions.
Window glass on new constructions must still be treated with a density pattern of between 10 and 28 centimetres apart or otherwise be able to mute reflections for at least the first 10 to 12 metres of a building, above grade.
The same goes for a requirement that builders ensure ground-level ventilation grates have a porosity of less than two centimetres by two centimetres.
Council adjusted new reduced light pollution targets “to make them a little clearer,” Welsh said.
New constructions and properties must reduce nighttime glare and light trespass, exterior light fixtures must be shielded to prevent glare or light trespasses onto neighbouring properties, and the city no longer allows up-lighting from exterior light fixtures unless a heritage designation applies.
The City has also added one requirement. When green roofs are built adjacent to glass surfaces, the glass must be treated to at least 12 metres above roof-level.
