Published on

The vision of Masdar City (the world’s first zero-carbon city to be created before 2020) was shared by the Masdar City team at a September 16, 2009, business-to-business seminar held at MaRS.

The seminar attracted nearly 70 cleantech suppliers, green technology leaders, government policy makers and sector funders. This presentation is from RWDI Consulting and Engineers on the opportunities in wind, microclimate, energy and thermal comfort, created for this seminar.

This was the vision shared by members of the Masdar City team at a September 16th business-to-business seminar held at MaRS. An attentive audience in Toronto was joined by participants in Edmonton and Vancouver via videoconference, indicating strong interprovincial interest.

The seminar - sponsored by the Ministry of Economic Development and Trade, MaRS and the Masdar City team- attracted nearly 70 cleantech suppliers, green technology leaders, government policy makers and sector funders.

  • Hello my dear
    I am Modester by name good day. i just went to your profile this time true this site (www.slideshare.net) and i got your detail and your explanation in fact the way you explain your self shows me that you are innocent and maturity and also understand person i decided to have a contact with you so that we can explain to our self each other because God great everyone to make a friend with each other and from that we know that we are from thism planet God great for us ok my dear please try and reach me through my email address (modester4life4@yahoo.com) so that i can send you my picture true your reply we can know each other ok have a nice day and God bless you yours Modester

  • 1) We’re not sure that all the undercroft pedestrian access points are PRT stations. Some, like Green-31 and Green-32, are not on the PRT corridor. Unless told otherwise, we will likely assume these can be removed (about 11 towers).

    10. 10. Is it too dark – the balance between daylight and energy consumption City to operate on 45watts per square meter per annum average Energy efficient lighting Natural ventilation schemes Building automation systems -2 to 3million sensors
    11. 11. Annual cumulative insolation on Residential cluster 1 wall surfaces - Yellow = 860 kWh/m 2 - Purple = 300 kWh/m 2 - Orange = 700 kWh/m 2 - Blue = 60 kWh/m 2 - Red = 460 kWh/m 2 - Black/Grey = not analyzed Annual Cumulative Insolation - Building Walls - Sample Output <ul><li>Levels of solar loading of the façade is shown and the positive effects of self shading is evident </li></ul>Overall Residential court-yard wall surfaces A self-shaded area North
    12. 12. How should I construct these walls so that they do not radiate heat after the sun goes down? How do I construct the exterior of the building to minimize heat transfer to the interior space? How do I do this cost effectively
    13. 13. If it is 40 degrees outside could I really sit on these materials? How much water do these trees need? How do we balance the human need for natural shade versus cost of a scarce resource?
    14. 14. It can be dusty!
    15. 15. Dust Reduces direct solar intensity by 40% Need to clean the panels frequently What technologies can you offer? Remember water is expensive!

Other strategies to increase performance are found in the reports. </li></ul><ul><li>Height of the panels above roof should be approximately 2m. </li></ul><ul><li>But the infrastructure cost is too high. Is there a cheaper support system? </li></ul>Insert diagrams of the roof angles 5 and 18 and 8+5 Self shading is critical issue
    17. 17. RWDI simulation of fire scenario. Upblast-type exhaust hood, often used for kitchen exhausts. Manifolded laboratory exhausts with tall stacks. Example exhaust from subway fire . Diesel generators on startup. Potential sources of air pollution Air Quality

    21. 21. Masdar Energy Design Guideline <ul><li>RWDI has developed a Masdar Energy Design Guideline (MEDG) to serve as a mandatory framework governing the design of energy efficient buildings in the city. </li></ul><ul><li>The goal of the MEDG is for buildings to have an 80% reduction in total annual energy demand compared to the current Abu Dhabi building standard, and a 50% reduction compared to ASHRAE 90.1-2007 </li></ul>What about those plug loads?
