Ushbu tezisda ma'muriy bino HVAC tizimida talabga asoslangan ventilyatsiya (DCV) uchun sensor va aktuator infratuzilmasi ko'rib chiqilgan. Belgilangan ventilyatsiya tezligi bandlikdan qat'i nazar doimiy bo'lib, energiya isrofi yoki yetarsiz ventilyatsiyaga olib keladi. Siemens QPA2062 NDIR CO₂ sensori, PIR harakat sensorlari va Belimo TSV24-SR VAV aktuatorlari kombinatsiyasi bandlikni ±1 kishi aniqlikda baholadi va CO₂ darajasini 1420 dan 940 ppm ga tushirdi. Birgalikdagi PIR+CO₂ algoritmi yillik ventilyatsiya energiyasini 18 600 kVt·soat (16,3%) tejadi.
