  • Typology for the Aesthetics and Top Design of Tall Buildings
    G.U. Journal of Science 22(4): 371-381 (2009) www.gujs.org Typology for The Aesthetics and Top Design of Tall Buildings Ayşin SEV 1♠ 1 Mimar Sinan Fine University, Faculty of Architecture, Building Technology Department, 34427 Istanbul, TURKEY Received: 16.02.2009 Revised: 11.05.2009 Accepted: 05.06.2009 ABSTRACT The morphological character and the top is the most important component of the tall building in terms of its impression in the city silhouette. Designers of attractive tall buildings, whose investors tend to create a symbolic image, mostly prefer tops with aesthetic expressions. However many tall buildings with slipshod tops create unidentified skylines as it is the case for many modern cities of today. In this paper, the particular issue of visual impact and tops of tall buildings are addressed and a historical category system of seven periods is proposed. Then each period is illustrated in a series of outline figures showing the comparative heights and profiles of leading examples within each category. As a result, it is recognized that tall building design is a holistic process, and it is impossible to consider formal and aesthetic principles in isolation without reference to technology of the era, as well as the investors’ demands. The impact of tall building tops involves a consideration of social values followed by scale and traditional design principles versus contemporary expression of architectural design objectives. Key Words : Tall buildings, skyline, skyscraper, high-rise, aesthetic, urban context. 1.

Introduction Rowan Williams Davies & Irwin Inc. (RWDI) was retained by ADD Inc. to assess the potential pedestrian wind conditions for the proposed Cambridge Discovery Park Building 400/500 Project located in Cambridge, MA (Image 1). We understand the project consists of a new 4-story bridge connecting two 6-story buildings with a roadway between them. There are concerns about the wind conditions around and under the bridge. The objective of this assessment is therefore to provide a qualitative evaluation of wind comfort conditions and recommend mitigation measures, if necessary.

  • Holistic Approach to Human Comfort
    Peer Review Holistic approach to Human Comfort Kevin M Peddie1 and Michael J Soligo2 1 Rowan Williams Davies & Irwin Inc., Sydney, NSW, Australia 2 Rowan Williams Davies & Irwin Inc., Guelph, Ontario, Canada E-mail: [email protected], [email protected] ABSTRACT The consideration for human comfort in the urban plane has largely been focused on the wind speed that a pedestrian might experience due to the surrounding built form design, prevailing winds and site exposure. As such, wind criteria have been developed by councils for precincts around the world which are focused on the wind speed for safety as well as being aimed at providing comfortable conditions for the intended uses. However, human comfort is not only affected by the experienced wind force, but also temperature, relative humidity, solar radiation, clothing and other parameters. A comprehensive model has been developed by RWDI for the assessment of holistic human comfort, including accounting for seasonal climate variance. This can also be further refined to consider other key parameters such as noise and air quality. This paper will demonstrate the application of a developed human comfort model which has been carried out for projects in different climate zones. It will detail the importance of considering all aspects, holistically, when determining the true comfort level for an outdoor microclimate. Subsequently, discussion will be provided on how the design community and planning authorities could utilise this assessment to greatly improve the usability and enjoyment of public spaces. INTRODUCTION The assessment of pedestrian comfort in public domain spaces has become of increased importance in society, with growing concerns for the environment and the quality of life provided in urban contexts.

Received: 26 July 2012; in revised form: 5 September 2012 / Accepted: 10 September 2012 / Published: 28 September 2012 Abstract: The tall building is the most dominating symbol of the cities and a human-made marvel that defies gravity by reaching to the clouds. It embodies unrelenting human aspirations to build even higher. It conjures a number of valid questions in our minds. The foremost and fundamental question that is often asked: Why tall buildings? This review paper seeks to answer the question by laying out arguments against and for tall buildings. Then, it provides a brief account of the historic and recent developments of tall buildings including their status during the current economic recession. The paper argues that as cities continue to expand horizontally, to safeguard against their reaching an eventual breaking point, the tall building as a building type is a possible solution by way of conquering vertical space through agglomeration and densification. Case studies of some recently built tall buildings are discussed to illustrate the nature of tall building development in their respective cities.

  • Design and Control of Hydronic Radiant Cooling Systems
    Design and Control of Hydronic Radiant Cooling Systems By Jingjuan Feng A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Architecture in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Stefano Schiavon, Chair Professor Gail Brager Professor Edward Arens Professor Francesco Borrelli Spring 2014 Design and Control of Hydronic Radiant Cooling Systems © 2014 By Jingjuan Feng ABSTRACT Design and Control of Hydronic Radiant Cooling Systems by Jingjuan Feng Doctor of Philosophy in Architecture University of California, Berkeley Professor Stefano Schiavon, Chair Improving energy efficiency in the Heating Ventilation and Air conditioning (HVAC) systems in buildings is critical to achieve the energy reduction in the building sector, which consumes 41% of all primary energy produced in the United States, and was responsible for nearly half of U.S. CO2 emissions. Based on a report by the New Building Institute (NBI), when HVAC systems are used, about half of the zero net energy (ZNE) buildings report using a radiant cooling/heating system, often in conjunction with ground source heat pumps. Radiant systems differ from air systems in the main heat transfer mechanism used to remove heat from a space, and in their control characteristics when responding to changes in control signals and room thermal conditions. This dissertation investigates three related design and control topics: cooling load calculations, cooling capacity estimation, and control for the heavyweight radiant systems. These three issues are fundamental to the development of accurate design/modeling tools, relevant performance testing methods, and ultimately the realization of the potential energy benefits of radiant systems.
