While an implied warranty of habitability is contained in every residential lease (Real Property Law § 235-b), and a landlord's failure to provide heat is a recognized breach of that warranty (see Park W. Mgt. Corp. v Mitchell, 47 NY2d 316, 328 [1979]), tenant here failed to offer any details whatsoever regarding the temperatures inside or outside the apartment and therefore "failed sufficiently to prove the dates, duration and intensity of the alleged deficiencies, [*2]relative to the outdoor temperatures, to permit the court to quantify the deprivation as an abatement" (Eke v Ayanru, 2002 NY Slip Op 40206[U], *2 [App Term, 2d Dept, 2d & 11th Jud Dists 2002]; see Sinclair v Ramnarace, 36 Misc 3d 150[A], 2012 NY Slip Op 51671[U] [App Term, 2d Dept, 2d, 11th & 13th Jud Dists 2012]). In light of this, and of tenant's failure to establish the extent and duration of the other conditions needing repair, the proof tenant offered at trial was insufficient to sustain the award of an abatement.
