Debate 1: Technical Consultants aren’t “Designers of Record”, so No E&O Insurance is Needed
Chair: E. Mitchell Swann
Today’s buildings are more complex than ever. Demands for higher performance, faster delivery and lower costs have spawned the growth of Energy Modeling, BIM development, in-field photogrammetry, Commissioning and Green consultants. These early-on consultants can have a big impact on final design decisions. Do they have professional liability similar to licensed design professionals? Should they carry PLI? If you've contracted out to consultants, have you verified their capacity to ‘handle’ the risks associated with the direction they provide? This debate will dig into the potentially dirty details and shifting terrain covered by tech consultants and the “responsible party.”
Seminar 17: Hotter Cities, Hotter Climates: Modelling and Measuring Urban Heat Island Effects Around the World WITH LIVE Q & A
Chair: Ralph Muehleisen, Ph.D., P.E.
Mitigating Urban Heat Island (UHI) or urbanisation-related weather issues is of critical importance for millions of urban dwellers worldwide. It affects building energy consumption and outdoor comfort, and has been associated with increased morbidity and mortality and worsening air quality. This makes quantifying these effects a priority for researchers and practitioners alike. In this seminar, we present (1) a review of the numerical modelling of urban heat island mitigation, and (2) a case study of blue and green mitigation of urban canyons based on measurements. The speakers discuss possible mitigation approaches to the problems highlighted.
1. Cooling Hot Cities: A Systematic and Critical Review of the Numerical Modelling Literature
Author: Evyatar Erell, Ph.D., Ben-Gurion University of the Negev, Beersheba, Israel
Infrastructure-based heat reduction strategies can help cities adapt to high temperatures, but simulations of their cooling potential yield widely varying predictions. To address this problem, a systematic review of published research was performed. First, studies were evaluated based on 25 criteria to assess contextualization and reliability, based on metadata reporting and methodological quality. High-quality studies were used to develop two new metrics: the Albedo Cooling Effectiveness (ACE) and the Vegetation Cooling Effectiveness (VCE). Albedo and vegetation strategies offer broadly similar magnitudes of cooling, but trees and ground-level vegetation offer somewhat more pedestrian-level cooling per area application compared with green roofs.
2. Case Studies of Blue and Green Mitigation of Urban Canyons
Author: Eric Peterson, Ph.D., P.E., University of Leeds, Leeds, United Kingdom
Reviewing case studies around the world compared with my observations and assessment of microclimates associated with water features and green infrastructure in Leeds, United Kingdom. These parks and ponds are set among “Brutalist” concrete canyons developed in late 20th century. Such case studies are important to assess the efficacy of measures that have been promoted to mitigate the impact of urban heat islands. A network of shaded temperature and humidity sensors can assess which urban precincts are safe operating environments. Are blue-green infrastructure sufficient to prevent pedestrians seeking shelter indoors in air-conditioned premises?
Seminar 58: How Will Climate Change Affect Standards, Guidelines, and the Way We Design? Part 1: Why Climate Change May Affect the Design of Buildings and Their Systems
Chair: Daniel Villa, P.E.
This is Part 1 of a 3-seminar series. Part 1 will introduce the new ASHRAE Fundamentals Handbook Chapter on Climate Change with a discussion of climate change issues which are anticipated to effect changes in some standards, guidelines and, eventually, codes. It will include a review of the newest climate zone maps with zone creepage, additional climate change related information and an exploration of questions of whether it is good practice to continue using 30-year historic weather data for load calculations in view of rapid climate change.
Seminar 59: How Will Climate Change Affect Standards, Guidelines, and the Way We Design? Part 2: Application to Loads Calculations and Design Conditions
Chair: Drury Crawley, Ph.D.
This seminar is Part 2 of a 3-seminar series. It will cover specific climate effects on the built environment and on loads calculations. The sessions seeks to show what areas are expected to need modification due to the changing climate and what areas do not need change. The session starts with issues specific to 90.1, looks at the effects of climate change on loads calculations, and then turns to the subject of appraising actual changes in design conditions due to climate through statistical analysis.
Seminar 60: How Will Climate Change Affect Standards, Guidelines, and the Way We Design? Part 3 Decarbonization by Smart Grid and Adaptation to Northern Warming
Chair: Parag Rastogi, Ph.D.
This is Part 3 of a 3-part seminar series. Part 3 looks at specific solutions and problems related to climate change. International standards concerning new building guidelines for the smart grid and their relationship to decarbonization is explored in the first presentation. The second presentation similarly explores how carbon emissions are changing with time in Minnesota and explores how the ASHRAE Smart Grid Guide can be used. The third presentation looks at warming in the Canadian north and associated adaptations that are needed.
