Lingkungan termal kota memegang peranan penting dalam tercapainya kenyamanan dan kualitas hidup seperti pada kondisi pandemi bencana dewasa ini. Perubahan iklim kota seiring berkurangnya area hijau merupakan permasalahan yang terus dihadapi, sehingga salah satu solusinya adalah pengembangan sistem penghijauan bangunan. Makalah ini fokus pada kinerja taman vertikal terhadap penurunan suhu udara, suhu permukaan dan kadar CO2. Metode yang dilakukan adalah pengukuran lapangan terhadap suhu udara, suhu permukaan, dan kadar CO2 di dalam dan luar bangunan seiring modifikasi jarak taman vertikal (0.5 m dan 1 m) serta jenis tanaman (bayam merah atau amaranthus hybridus, sawi atau brassica juncea, seledri atau apium graveolens linn, dan kumis kucing atau orthosiphon spicatus). Rata-rata penurunan suhu udara sebesar 0.75°C, sedangkan untuk suhu permukaan sebesar 16.4ºC serta penurunan kadar CO2 rata-rata sebesar 58.8 ppm. Hasil penelitian menunjukkan pengurangan suhu udara maksimal sebesar 6ºC dicapai oleh tanaman bayam merah dengan jarak 0.5 m. Perbedaan suhu permukaan maksimal sebesar 26.3ºC oleh tanaman bayam merah. Penurunan kadar CO2 terbesar oleh jenis tanaman Seledri sebesar 124 ppm. Implikasinya, semakin dekat jarak dan semakin gelap warna daun serta jenis tanaman bayam merah menjadi pertimbangan utama penerapan taman vertikal pada rumah di perkotaan melalui kemampuannya dalam menurunkan suhu pada lahan terbatas.
