I am working with a community to increase their overall window transparency for pedestrian comfort. Many of the office tenants have fully drawn window blinds on street front spaces, making the space as attractive from a pedestrian standpoint as a brick wall. What are some alternative strategies that they can present to these tenants that will provide more transparency while still protecting privacy and preventing sun glare? We just want to be able to provide 'best practices' that they can suggest. An ordinance is not likely to succeed.
