37 YEŞİL BİNA / AĞUSTOS 2016 Overview of New Construction M&V Options Akım şeması soğutma, havalandırma ve aydınlatma gibi sistemleri büyük ölçüde gerçeğe yakın modellenebilmektedir. Ancak doğal havalandırma, free cooling, gün ışığı aydınlatması, yüksek ekserji perfor- mansına sahip hibrid mekanik tesisat sis- temleri (trijenerasyon, ısı pompaları, ısıl depolama, güneş enerjisi, kazan, chiller), gölgeleme vb. bazı simülasyon programla- rında tam olarak modellenememektedir. Burada kullanılan EDSL TAS programının bu gibi sistemleri modelleyebilme kapa- sitesi bulunmaktadır. Bu çalışma için kaynaklar bölümünde verilen literatür ve EDSL TAS simülasyon programı kulla- nılmıştır. ENERJİ MODELLEMESİNİN DOĞRULANMASI (VERIFICATION OF ENERGY MODELLİNG) Bu husus, Kaynaklar bölümünde 12. sırada verilen IPMVP dökümanında geniş biçimde açıklanmıştır. Yukarıda ve yanda ise bu çalışmayı ilgilendiren M&V Option How Baseline is Determined Typical Applications A. Partially Measured Retrofit Isolation Savings are determined by partial measurement of the energy use of the system(s) to which an ECM was applied, separate from the energy use of the rest of the facility. Some parameters are stipulated rather than measured. B. Retrofit Isolation Savings are determined by full measurement of the energy use and operating parameters of the system(s) to which an ECM was applied, separate from the rest of the facility. C. Whole Facility Savings are determined at the whole-building level by measuring energy use at main meters or with aggregated sub-meters. D. Calibrated Simulation Savings are determined at the whole-building or system level by measuring energy use at mainmeters or sub-meters, or using whole building simulation calibrated to measured energy use data. Projected baseline energy use is determined by calculating the hypothetical energy performance of the baseline system under post-construction operating conditions. Projected baseline energy use is determined by calculating the hypothetical energy performance of the baseline system under measured postconstruction operating conditions. Projected baseline energy use determined by measuring the whole-building energy use of similar buildings without the ECMs. Projected baseline energy use is determined by energy simulation of the Baseline under the operating conditions of the M&V period. Lighting system where power draw is periodically measured on site. Operating hours are stipulated Variable speed control of a fan motor. Electricity needed by the motor is measured on a continuous basis throughout the M&V period. New buildings with energy-efficient features are added to a commercial park consisting of buildings of similar type and occupancy. Savings determination for the purposes of a new building Performance Contract, with the local energy code defining the baseline.
