Abstract

Aerogel is a sort of engineered porous substance. It has unique chemical and physical properties with different types of opaque and translucent. It is considered one of the most encouraging materials in various applications such as spacecraft and buildings. In building, translucent aerogel uses for window construction. It plays a vital role in enhancing building thermally and acoustically. Despite its high cost, aerogel is a brittle material. It is hard to produce large-sized free crack windows and prevents the window from being operable. It is not optically transparent, which isolates occupants from the outside view. These limitations restrict architects from using aerogel as windows on façades freely. Improved aerogel windows can get better efficient glasses, larger sizes, and transparency that experiences the natural quality of the light and outside view. It may give the building more functional façades that can fulfill people’s needs in the future. So, the study will evaluate the efficiency of façade in the future. The study aims to predict the capability of improved aerogel in creating a façade that achieves human needs while increasing the efficiency of the building from different perspectives. It examines improved aerogel windows and their role in enhancing current residential buildings in northern Iraq. Ecotect and Dialux software are used as research tools. The paper concluded that the capability of improved aerogel will give the building a new façade that is more environmentally friendly and provides human comfort while still transparent compared to the current facade.

Highlights

  • Nodaway's major issue occupying the human mind is building energy savings

  • Aerogel is a fragile material, weak to the tensile strength [7]. It prevents the aerogel window from being operable and is recommended as a fixed window to prevent cracks [11]

  • The casual analysis shows improved aerogel's capability to enhance the main functions of the window as a part and the building façade as a whole

Summary

INTRODUCTION

Nodaway's major issue occupying the human mind is building energy savings. The main reason people are busy with energy-saving is that the earth's surface temperature increased by nearly 0.6-0.9 C° between 1906 and 2005 [1]. Aerogel is a material where firstly produced in the 1930s [7] It is defined as the most effective building thermal insulation. As an indispensable part of the building, have essential functions It provides the spaces outside view, natural ventilation, and natural light to obtain occupant's comfort. For this purpose, this research investigates improved aerogel's impact on the façade function of a typical residential building in North Iraq. Manuscript received 3 September, 2021; revised 21 November, 2021; accepted 5 January, 2022; published 19 January, 2022 The research compared the performance of three window types (typical, current aerogel, and improved aerogel)
