Overall Thermal Transfer Value (OTTV)

Adalah nilai rata-rata kalor panas yang masuk ke dalam bangunan melalui rambatan panas benda padat (konduksi) selubung bangunan dan rambatan panas melalui gelombang cahaya (radiasi).

Dalam perancangan facade, windows dan skylight pada bangunan tropis perlu diperhitungkan nilai OTTV agar ruangan tidak panas berlebihan atau meringankan beban pendinginan AC sehingga di dapatkan ruangan yg sejuk dan hemat energi.
