EF 6
Increase AllowableSize of Solar Shades
Issue:Shading devices help combat heat gain and preventglare, decreasing cooling energy requirements. The
Building Code only permits these shading devices toextend 10 inches from the building, thus restrictingtheir effectiveness. They are also not permittedobstructions under the Zoning Resolution.
Recommendation:Treat shading devices the same as awnings andcanopies, which are permitted to extend fivefeet from the building. Also add these devicesto the list of permitted obstructions in theZoning Resolution.
Benefits Costs
EF 6: Solar shades were a common featurein New York City prior to the advent of airconditioning systems, as seen in this photo
of an awning-encrusted Flatiron building.

Reduce Artificial LightingIn Sunlit Spaces
Issue:Many of New Yorks buildings have been designedto maximize daylight in interior spaces. However,these buildings often waste energy by usingartificial light when daylight could provide much ofthe required illumination.

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.

which is allowed to be visible from the street.

Reduce Summer Heat with Cool RoofsIssue:Light-colored roofs reflect light and heat backinto the atmosphere, thereby cooling buildingsand cities. The building code mandates white roofcoatings, but the standards are not aligned withLEED, which is used by many developers.

Improve Energy Modeling
for Building Design
Issue:ASHRAE 90.1 allows designers to follow aprescriptive path or to use energy modelingto demonstrate compliance. Energy modeling,however, is prone to manipulation because it letsenhanced efficiency in one energy system be tradedoff against poor efficiency in another system.
Recommendation:Require projects using energy modeling todemonstrate design energy use that is 14% lowerthan the prescriptive path.

Increase Lighting Efficiencyin Apartment Buildings
Issue:The current lighting requirements in the HousingMaintenance Code for hallways, stairs, and commonlaundry facilities reference an old terminology forlighting, the use of incandescent lights. They alsoimply that the lights in hallways, stair, and commonlaundry facilities should always be fully on.
Recommendation:Update the language in the code to match othercity codes, particularly the energy code. Specifya minimum efficacy for light bulbs, and expresslyallow bi-level lighting for hallways and stairs, and
occupancy sensors for laundries.

Reduce Lighting PowerRequirements for Offices
Issue:An outmoded provision of the Electrical Codemandates that spaces have capacity to deliverthree times the power for lighting as is allowedunder the Energy Code. This increases cooling loadrequirements, necessitating oversized, expensiveHVAC systems.

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.
