1. Various of plants and greenery on the rooftop of Nomura PLC’s European headquarters in London, showing the wider city skyline
2. Various of Oscar Brousse, Senior Research Fellow in Urban Climatology and Health at University College London, taking temperature readings on top of the ‘green roof’ on top of Nomura PLC’s London headquarters
3. SOUNDBITE (English) Oscar Brousse, Senior Research Fellow in Urban Climatology and Health at University College London:
"Cool roofs: the principle is that the energy that is coming from the sun is reflected back straight to the atmosphere and into space. So, this energy that is coming in the first place is simply not accumulated in the city, in the buildings, in the streets, etc."

6. SOUNDBITE (English) Oscar Brousse, Senior Research Fellow in Urban Climatology and Health at University College London:
"So, there are two types of heat. There’s the one that we can feel. Like if you put your hand on top of a hot pan this is the type of heat that you will feel, and this is the one that will heat up the air. And there’s the one that you can’t feel, and you can’t experience which we call latent because it’s absent and actually plants, by transpiring, that’s by sweating as we do, emit more heat into that form of latent heat, the heat that you can’t perceive, so it’s water vapour basically."

10. SOUNDBITE (English) Oscar Brousse, Senior Research Fellow in Urban Climatology and Health at University College London:
"The heat that is stored in the soil in which the plants are, that will be released in this form of sensible heat that you can feel, and they will heat up the air at night – which was what we found in our study. Basically, green roofs do decrease air temperature, or are expected to do, but on average throughout the day because they heat up also the air at night, you get this kind of null average decrease in temperature."

12. SOUNDBITE (English) – David Crowley, Environmental Manager at Nomura PLC:
"I think the more green roofs that we can get, especially in these highly urban areas the better. There’s a lot of wildlife out there that still need to thrive. Be it birds, be it moths, butterflies, bees, butterflies… There’s many species of creatures that need this kind of habitat. The more we can do to enhance that, it’s going to enrich our lives as well."
