Nanotechnology developed nanomaterials as environmentally friendly and highly efficient construction materials. It behaves differently with enhanced functional properties such as durability, strength, flexibility, lighter weight, self-cleaning capacity, etc. This study investigated the impact of integrating nanotechnology into the construction field from two perspectives: to minimize the environmental impact of buildings based on sustainability principles and to improve the functional efficiency of construction materials. The study aims mainly to propose a strategy for evaluating nanomaterials in construction as sustainable materials through four aspects related to sustainability principles. This was achieved progressively through a methodology that commenced with a theoretical study of the basics of nanotechnology and how it relates to the field of sustainable architecture. Moreover, it described and summarized some prevailing nanomaterials used in construction, such as concrete, glass, coatings, and thermal insulation materials. It also reviewed their functional efficiency in line with sustainability. Furthermore, this study examined some case studies based on the proposed strategy to evaluate the utilized nanomaterials in the case studies. On average, this study's results found that the used nanomaterials in the three case studies achieved 54.3% for sustainable design principles, 83% for Sustainable materials criteria, 60.3% for energy efficiency aspects, and 71.7% for ambient environment efficiency factors. On the other hand, it indicates that using nanomaterials in construction reduces harmful carbon emissions and improves the functionality of building materials to boost sustainable architecture. Keywords Sustainable Architecture, Nanotechnology, Nanomaterials, Nanoarchitecture 1. Introduction 1.1. Background Nanoscience is the science of studying the properties of materials at the atomic level. Atoms can be controlled and manipulated on a scale not exceeding 100 nanometers, called the nanoscale. At this scale, materials gain a wide range of improved properties, including shape, color, strength, weight, conductivity, and elasticity. [1,2]. In Greek, Nanos means dwarf, minimal size, so the prefix Nano is derived from it [3]. Microscopic studies show that when the gold particles are nanosized, they could give different color reflections, such as red, depending on the size and shape of the particles and the distance between them [4]. Several applications of nanotechnology have gained momentum recently. The following are a few keys Nanotechnology definitions: (a) A nanometer is a metric unit of measure equal to a billionth of a meter, or 10 -9 meters (1/1000000000) [5]. (b) Nanoscale "The size ranges from roughly 1 to 100 nanometers, where many of the fundamental structures of biology are formed, composite materials
