Definitions for

**"Loss factor"**The percentage of the space attributed to the common areas of the building, or the proportional share of common areas attributed to a specific space.

A term used correctly only in conjunction with the REBNY Standard to mark-up Usable Area to Rentable Area, allocating common areas of the building to each floor and tenant. Functions similarly to the BOMA R/U Ratio but expressed differently.

The common area calculation used to convert usable square foot measurements (usually, the physical space actually occupied by the tenant) to rentable square foot calculations. Usually includes a pro-rata share of restrooms, lobby, common hallways, mechanical equipment rooms, etc.

a factor included in the calculation of abstraction charges under the Agency's Scheme of Abstraction Charges to represent the loss to the water resource system resulting from the licensed use of water [see EA Scheme of Abstraction Charges].

A property of an elastomer which is a measure of the amount of damping in the elastomer. The higher the loss factor, the higher the damping. Loss factor is typically given the Greek symbol "ÃŽÂ·". An approximation may be made that loss factor is equal to the inverse of the resonant transmissibility of a vibratory system. The loss factor of an elastomer is sensitive to the loading and ambient conditions being imposed on the system.

The product of the power factor and the dielectric constant. Back to the top
