Case study for comparative analysis of BIM-based LEED building and nonLEED building

Abstract

The objective of this study is to design a sustainable high-rise residential building using Leadership in Energy and Environmental Design (LEED) and Building Information Modeling (BIM) and perform comparative analysis for the LEED building and non-LEED building. In this scope, the additional cost related to water and energy efficient systems and the additional total cost for the LEED building were analyzed to calculate the respective break-even points. The research methodology relies on the literature review and case study. In the case study, the 3D model of a 15-storey residential building was designed via Autodesk Revit 2019 based on the LEED v4.1 Building Design and Construction (BD+C) rating system. The case study building can achieve 31 credits and 9 prerequisites which allow to obtain 61 points and LEED Gold certificate. By applying LEED v4.1 BD+C procedures, water consumption of the building was reduced by 65.96%, and energy consumption of the building was decreased by 59%. The initial cost of LEED building is 1,074,833.04 TL which is 852,230.64 TL higher than the initial cost of non-LEED building. According to the break-even point calculations, the additional total cost of LEED building can be charged after 13 years 8 months and 12 days. Results make a significant contribution to the literature and industry by showing the requirements and design process of a high-rise residential building using LEED and BIM. This study adds original value to the literature and industry by ensuring practitioners and researchers with constructive information about the energy, water, and cost performance of LEED buildings. Further, results provide an insight to professionals in the architecture, engineering, and construction industry about the value of green buildings.

BIM tabanlı LEED binası ile LEED olmayan binanın karşılaştırmalı analizi için vaka çalışması

Öz

Bu çalışmanın amacı, Enerji ve Çevre Tasarımında Liderlik (LEED) ve Yapı Bilgi Modellemesi (BIM) kullanarak sürdürülebilir yüksek katlı bir konut binası tasarlamak ve LEED binasi ve LEED olmayan bina için karşılaştırmalı analiz yapmaktır. Bu kapsamda, su ve enerji verimli sistemlerle ilgili ek maliyetler ve LEED binası için toplam ek maliyet analiz edilerek ilgili başabaş noktaları hesaplanmıştır. Araştırma yöntemi, literatür taraması ve vaka çalışmasına dayanır. Vaka çalışmasında, 15 katlı bir konut binasının üç boyutlu modeli, LEED v4.1 Bina Tasarım ve İnşaat (BD + C) derecelendirme sistemine dayalı olarak Autodesk Revit 2019 aracılığıyla tasarlandı. Vaka çalışması binası, 61 puan ve LEED Gold sertifikası elde etmeyi sağlayan 31 kredi ve 9 önkoşul sağlayabilir. LEED v4.1 BD+C prosedürleri uygulanarak, binanın su tüketimi %65.96’ya, binanın enerji tüketimi ise %59’a kadar azaltılmıştır. LEED binasının başlangıç maliyeti 1,074,833.04 TL olup, LEED olmayan binanın başlangıç maliyetinden 852,230.64 TL daha fazladır. Başabaş noktası hesaplamalarına göre, 13 yıl 8 ay 12 gün sonra LEED binasının toplam ek maliyeti tahsil edilecektir. Sonuçlar, yüksek katlı bir konut binasının gereksinimlerini ve tasarım sürecini LEED ve BIM kullanarak sunup literatüre ve sektöre önemli katkı sağlar. Bu çalışma, uygulayıcılara ve araştırmacılara LEED binalarının enerji, su ve maliyet performansı hakkında yapıcı bilgiler sağlayarak literatüre ve sektöre özgün bir değer katmaktadır. Ayrıca, sonuçlar mimarlık, mühendislik ve inşaat sektöründeki profesyonellere yeşil binaların değeri hakkında fikir vermektedir.
