The Energy Analysis For Net Zero Energy Building Using Hourly Analysis Program: A Case Study Of A Residential Building In Baghdad

Abstract

This study investigates the impact of exterior paint and insulation on the thermal loads of a residential building in Baghdad during summer and winter. The heating and cooling loads, which determine the energy required for maintaining indoor temperatures, were analyzed. Results show that insulation significantly reduces cooling loads by half, with a living room’s cooling load decreasing from 6.8 kW to 3 kW when insulated. Similarly, the heating load dropped from 3.3 kW to 1.6 kW without insulation. The effectiveness of different coating types also influences thermal loads. The Variable Refrigerant Flow (VRF) system requires 5.94 kW in summer and 3.66 kW in winter to achieve a net-zero state. Solar panels are essential for meeting these demands. The HAP and Trace 700 programs were utilized to simulate conditions, resulting in a 5% variance, indicating reliable and acceptable outcomes.

Hourly Analysis Program Kullanarak Net Sıfır Enerji Binası İçin Enerji Analizi: Bağdat'ta Bir Konut Binası Üzerine Bir Vaka Çalışması

Abstract

Bu çalışma, yaz ve kış dönemlerinde Bağdat'taki bir konut binasının ısı yükleri üzerindeki dış cephe boyası ve yalıtımın etkisini araştırmaktadır. İç mekan sıcaklıklarını korumak için gereken enerjiyi belirleyen ısıtma ve soğutma yükleri analiz edilmiştir. Sonuçlar, yalıtımın soğutma yüklerini önemli ölçüde yarıya düşürdüğünü göstermektedir; yalıtım uygulandığında oturma odasının soğutma yükü 6.8 kW'dan 3 kW'a düşmektedir. Benzer şekilde, yalıtımsız durumda ısıtma yükü 3.3 kW'dan 1.6 kW'a gerilemiştir. Farklı kaplama türlerinin etkinliği de ısı yüklerini etkilemektedir. Değişken Soğutucu Akışkan (VRF) sistemi, net sıfır duruma ulaşmak için yaz aylarında 5.94 kW ve kış aylarında 3.66 kW gerekmektedir. Bu talepleri karşılamak için güneş panelleri hayati öneme sahiptir. HAP ve TRACE 700 programları, koşulları simüle etmek için kullanılmıştır ve %5’lik bir varyans elde edilmiştir; bu da güvenilir ve kabul edilebilir sonuçlar göstermektedir.
