Roof plan architecture11/10/2023 where prominent tall buildings are constructed on small sites with pedestrian and vehicular traffic mere feet from their base, the tolerance for any potential hazard or interruption of building operations due to falling ice and snow, or the erection of yellow "caution tape" is significantly less. In densely populated urban centers, such as New York City, Boston, Chicago, Toronto, Denver, and Washington D.C. On larger commercial or public buildings the issues are largely the same however, the potential for damage or injury grows as building surfaces are larger, buildings are taller, and the volume of pedestrian and vehicular traffic increases. Sliding snow from residential roofs has damaged cars, blocked exits, or even torn off gutters and flashing details. Buildings in cold climates have struggled throughout the ages with ice and snow formations that slide, fall, or get windblown from their roofs, ledges, and window sills, causing harm to people and damage to property below. The following text has been created to raise awareness of an old topic that is of growing concern based on some current trends in the economy and industry at large. Further it is important to note that the occurrence of hazardous winter ice and snow formations cannot be eliminated and can only at best be reduced in frequency or severity. That said, the purpose of this particular resource page is to bring awareness to one specific non-physical microclimate factor for consideration in design: winter weather or winter precipitation and its potential for hazardous conditions to people and property if not adequately anticipated. The purpose of conducting these non-physical studies is traditionally two-fold first to understand the existing microclimate of the site from the various points of study and secondly to predict the negative impacts, interaction, and influence of the proposed building design on the microclimate and modify the design to mitigate negative impact.Ĭonsequently, the effort to create an aesthetically pleasing, efficient, and economical plan can have immense challenges and trade-offs. The term "microclimate" is defined by as: "the essentially uniform local climate of a usually small site or habitat". These last non-physical examples have been traditionally grouped into an area called Environmental or more accurately Microclimate Studies. These factors often include the analysis or impact of: radiant solar angles, sun shadows, noise, vibration, wind force, air quality, pedestrian level winds, snow loading, etc. This task of optimizing the readily observable attributes of a plan to its physical landscape can be a daunting task further complicated by the analysis of additional unseen non-physical factors. Orientation of the future building's footprint, entrances, exits, glazing, interior spaces, etc., are prudently arranged and manipulated to create the most aesthetically pleasing, efficient, and economical plan for the desired use of form and function. In the creative process of building design, a great deal of consideration is given to the physical landscape of a development. The following information is general in nature, consequently the application of the concepts discussed in real world conditions will vary based on project specific performance considerations and site specific microclimate conditions unique to each project, geographic location and building façade. The content of this section of the BEDG in the WBDG is intended solely as a means to create awareness of the relevant topics and concepts.
