Abstract

In this study, energy, exergy, and anergy analyses related to eight types of coatings and paints consisting of white paint, aluminium, red brick, black paint, black metal coating, concrete, marble and porcelain-tile were made which applied to the external wall of the buildings envelope with the highest surface area. Balikesir province from the second climate zone was accepted for all examinations based on TS 825. Accordingly, energy consumption exergy and anergia were calculated. The degree-day method was used for energy consumption calculations. For degree-day calculations, solar air temperature values were determined. While calculating solar air temperature values, absorbance and emissivity values were found for eight coatings and paints. As a result, when the heating and cooling periods are considered together, depending on the energy consumption, the highest exergy in the north direction is 21.405 kWh/m2, and the lowest exergy is the metal black-coated outer wall using natural gas energy source for the white painted exterior wall surface using a coal energy source. It has been determined as 5.118 kWh/m2 in the south direction for the surface. In addition, temperature dependent decrement factor was determined for the exterior walls of the building due to different paints or coatings.

Binaların Dış Duvarlarının Yüzey Özelliklerine Bağlı Enerji Tüketim Analizleri ve Sıcaklık Sönüm Faktörü

Abstract

Çalışmada, binaların yapı kabuğunun en yüksek yüzey alanana sahip dış duvarlarına uygulanan; beyaz boya, alüminyum, kırmızı tuğla, siyah boya, metal siyah kaplama, beton, mermer ve porselen-çini den oluşan sekiz çeşit kaplama ve boyalarına bağlı enerji, ekserji ve anerji incelemeleri yapılmıştır. Tüm incelemeler için TS 825’e ikinci iklim bölgesindeki Balıkesir ili kabul edilmiştir. Enerji tüketimi, ekserji miktarı ve Anerji değeri hesaplanmıştır. Enerji tüketimi hesapları için derece gün yöntemi kullanılmıştır. Derece gün hesapları için güneş hava sıcaklık değerleri hesaplanmıştır. Güneş hava sıcaklık değerleri hesaplanırken sekiz çeşit kaplamalar ve boyalar için soğurganlık ve yayıcılık değeri tespit edilmiştir. Sonuç olarak, ekserji miktarı enerji tüketimine bağlı olarak ısıtma ve soğutma dönemi birlikte düşünüldüğünde kömür enerji kaynağı kullanan, beyaz boyalı dış duvar yüzeyi için, kuzey yönünde en yüksek 21.405 kWh/m2 ve en düşük ise doğal gaz enerji kaynağı kullanan metal siyah kaplamalı dış duvar yüzeyi için güney yönünde 5.118 kWh/m2 olarak tespit edilmiştir. Ek olarak bina dış duvarları için farklı boya veya kaplamalara bağlı dış duvar için sıcaklığa bağlı sönüm faktörü tespit edilmiştir.
