Greening a city is a task with many aspects and in this webcast we hear from someone with experience of several of these.

Tricia Lee's job description as a Certified Energy Manager and Director of New York-based consultancy CodeGreen Solutions is about making buildings more efficient with LEED. But she wears two other hats, being involved with a project to improve air quality in US cities and another to do with community gardens in New York City.  

She discusses her work with a non-profit organization called Urban Air Foundation dedicated to improving the air quality in US cities.

This works with real estate owners and she tells us how and what's in it for them. 

She also works on community urban gardens, helping to design a self-sustaining kit to serve as a replicable model in these gardens in partnership with the New York Restoration Project, which aims to plant one million new trees in New York City by 2017. It works in 52 community gardens. 

She gives her views on whether new mayor of NYC Bill de Blasio will continue the MillionTreesNYC campaign and Bloomberg's other green initiatives  

She also works with building and facility managers helping buildings achieve LEED energy efficiency compliance. She discusses whether compliance should be compulsory on some kind of energy efficiency standard as it is in the UK and other countries. 

Patricia believes that engaging the public is the single most important thing that can be done to move towards greater sustainability in cities.
