Paper Title
Feasibility Study of Smart Materials Usage in Outdoor Spaces

Abstract
Outdoor spaces contribute to a large extent towards the problem of resources depletion. These spaces include built environment, landscape elements and lighting fixtures which consume a lot of energy sources. These spaces also are in continuous subjection to high levels of vandalism and deterioration, leading to frequent maintenance requirements. Nanotechnology offered new means towards adjusting the properties of materials to invent new smart materials, which are able to react towards the surrounding environment. In architecture, they are considered as alternatives for traditional materials as they suggest the feasibility of energy consumption and frequent maintenance requirements reduction, improving building performance and protecting more resources from depletion, for more sustainable architecture and environment. Objective: To illustrate smart materials various application in outdoor spaces as coatings, lighting fixtures and furniture Aim: To evaluate the feasibility of smart materials usage in outdoor spaces to reduce the energy consumption and high frequency maintenance requirements with minimum environmental impact. Methodology: A case study was conducted in Heliopolis Sporting Club, Cairo in Egypt. Comparative analysis was conducted to compare between smart materials and existing materials and their capability to reduce the club energy consumption and the cost of its frequent maintenance with minimum environmental impact. Keywords- Smart materials, Nano coatings, Smart materials applications, Energy Efficiency.
