  • ABSTRACT the Main Feature of a Conventional Terraced Housing Development Is Rows of Rectangular Shaped Houses with the Narrow Fa
    MAKING A RETURN ON INVESTMENT IN PASSIVE ARCHITECTURE TERRACED HOUSES DEVELOPMENT Wan Rahmah Mohd Zaki Universiti Teknologi Malaysia(UiTM) Malaysia E-mail: [email protected] Abdul Hadi Nawawi Universiti Teknologi MalaysiaQJiTM) Malaysia E-mail: [email protected] Sabarinah Sh Ahmad Universiti Teknologi MalaysiaQJiTM) Malaysia E-mail: [email protected] ABSTRACT The main feature of a conventional terraced housing development is rows of rectangular shaped houses with the narrow facade as the frontage. Consequently, this limits natural cross ventilation and daylight penetration into the middle of the houses; and cause for unnecessary energy consumption on mechanical cooling and artijicial lighting to make the living spaces comfortable for occupants. Such inconsideration is mainly attributed to the optimum configuration of houses which offers the most economic return desired by the developer. Passive Architecture (PA) design strategies can make terraced houses more conducive for occupants as well as gives reasonable returns to the developer. The idea is demonstrated on a hypothetical double storeys terraced scheme in a 2.5 acre site whereby it is transformed intofour types of PA terraced houses development. The Return on Invesfment of the PA terraced houses is ascertained for two situations, ie., (i) fwed sales price for all types of house; and (ii) added premium to PA terraced houses due to the positive unintended effects such as low density housing, etc. If critical criteria for demand and supply in housing remain constant, it is found that PA terraced housing development offers competitive returns to the developer relative to the returns for conventional terraced housing scheme. Keyworh: Orientation, Indoor Comfort and Operational Energy 1.0 INTRODUCTION 1.1 Housing and Energy The recent public awareness on sustainability calls for housing to not only serves as a basic shelter but also to be energy efficient, i.e., designed to make occupants need low operational energy.

  • Ornament and European Modernism: from Art Practice to Art History
    Ornament and European Modernism: from art practice to art history Review of: Ornament and European Modernism. From Art Practice to Art History, by Loretta Vandi (ed.), New York and London: Routledge, 2018, 198 pp., 38 colour & b/w illus. £110,00, ISBN: 978-1-138-74340-3 Ariane Varela Braga After a rejection that lasted almost one century, ornament has made a comeback that is no longer possible to ignore. This renewed interest in ornamental and richer decorative forms has spread from architecture to design, fashion and the visual arts in general. Ornament seems to have finally regained its place among the arts and has become once again a matter of reflection and experimentation, involving various materials and media. Adolf Loos’ aggressive condemnation in Ornament und Verbrechen (1910) appears now a long way off. This renewed interest has not left untouched the field of art and architectural history. Since the 1990s, and even more so since the beginning of this new century, studies have multiplied all over the world, involving an ever broader temporal and cultural panorama. This has led to numerous publications on the use, function and history of ornament, as well as the promotion of new editions of historical treatises, drawings and pattern books, in both printed and digital versions.1 These studies, which seem to increase every year,2 have not been limited to the Western arts, but 1 A recent example in this sense is Sabina de Cavi, ed, Giacomo Amato.
