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.

At the time those tests were conducted, the list of cumulative schemes did not include the proposed Cuba Street development, located to the northwest of the proposed Alpha Square site. Under instruction from the Developer, Far East Consortium International Ltd, a further series of wind tunnel test has been conducted with the Proposed Development with cumulative surrounding buildings including the future Cuba Street development. Furthermore the proposed landscaping scheme (included in the planning application) was used as a starting point for the mitigation workshop. During the workshop, the specific details of the proposed landscaping scheme within the Site and additional mitigation along Bellamy Close and Cuba Street were investigated and are described in detail within this further information addendum report.
