WIND TURBINE AND COURTYARD COVER

Ayesha Husain

Version 2 - 2/26/12

The NYC Green Code Task force promotes

multiple environmentally conscientious

proposals to bring the city standard up near

or past the standard created by LEED. The

renewable energy sources in the task force

feature roof-top solar generation; all othertypes of energy generation are ignored.

Dense urban spaces tend to channel wind

into tunnels, at time creating quite a bit of

wind speed. I propose to utilize urban wind

as a source for generating energy. My goal

is to utilize the intent to the green code to

provide renewable energy sources and

propose a new section to be added regarding

wind.

EF 14

Allow Large SolarRooftop Installations

Issue:Current regulations limit the area of roof that solar

panels can cover without counting as another floor.This can increase the effective cost of solar panels,or prevent their installation.

Recommendation:Exempt solar panels from limits onrooftop coverage.

EF 15

Remove Zoning Impedimentsto Alternative Energy

Issue:The Zoning Resolution allows many categories of

mechanical equipment on a roof to exceed theallowable building height. However, equipment usedfor alternative or distributed energy is not treated assuch a permitted obstruction.

Recommendation:Treat alternative and distributed energy equipment,such as photovoltaic and solar thermal collectors, aspermitted obstructions.

EnergyFrom AwayEven though NYC generates asignificant portion of its ownenergy, the great majority ofelectrical power is delivered tothe city through a transmission gridthat collects energy from distantpower plants. As much as 70% ofthe fuel consumed in the generationof power for the grid is lost during

generation and transmission.Removing impediments torenewable energy within NYC willmake the power grid more reliable,reducing the risk of blackoutsand brownouts.

EF 16

Remove Landmarks Impedimentsto Alternative Energy

Issue:In historic districts, rooftop equipment including solar panels, wind turbines and micro-turbines -- is not permitted if visible from thestreet without a lengthy review by the LandmarksPreservation Commission.

Recommendation:Treat alternative and distributed energy equipmentthe same as other rooftop mechanical equipment,

which is allowed to be visible from the street.

Awareness =

EfficiencyNew York State studies have shownthat metering tenant electrical usein a multi-famliy building can reduceapartment electricity consumptionby approximately 17%-27%.

EO 2

Measure Electricity Usein Tenant Spaces

Issue:Because electricity is often unmetered incommercial tenant spaces, tenants are unaware ofthe energy they consume. This, in turn, can lead toexcessive use and waste.

Recommendation:All new commercial tenant spaces of 10,000 squarefeet or larger shall be metered for electricity. Asimilar proposal was incorporated into the Greener,Greater Buildings Plan, which became law prior tothe issuance of this report.
