Energy efficient prefabricated housing units: Product review and the development of a Cypriot paradigm

Abstract

This paper aims to examine the features and elements that govern the design and construction process of a bioclimatic, smart, prefabricated housing unit. The study is based on a review of the current literature and a taxonomy of current and proposed applications based on different prefabricated building typologies and fabrication methods. The proposed research also aims to evaluate the design implications and the performance of construction and energy components that maximize the unit's design and energy potential. All cases will be addressed in terms of the challenges faced both by conforming to and enhancing the architectural design concept, as well as by optimizing the overall design performance and minimizing the energy consumption of the building. The paper delves also into the investigation, assessment and categorization of the main characteristics of existing integrated technologies through case studies, analysing the type and the use of each case. Thereafter, an evaluation of the performance of the various typologies under examination is carried out in order to identify the best practices for different applications. Subsequently, a preliminary proposal for a "Prefabricated, ECO Smart Housing Unit", based on local technical knowledge, and the prevalent fabrication conditions in Cyprus, is presented based on the conclusions drawn from the assessment and categorization of previous sections. The ultimate aim of this effort is to critically present the breadth of typologies and the plethora of alternatives that can be applied on a green prefabricated building unit, in ways that maximize its design and energy potential.
