Jud seeks to understand how externally-forced and internally-driven changes affect the earth’s climate. He uses paleoclimate archives to help evaluate both current climate trends and climate models, which are used to project future changes. Jud focuses on producing long records of hydroclimate using speleothems, corals, and forams from the tropics as well as quantifying the uncertainty of climate reconstructions and then comparing the paleoclimate data to climate model output.
Topic: Climate Change: Past, Present, Future – How It Will Affect Building Design and Resiliency
This lecture covers how climate has changed in the past, current climate changes, and how climate is predicted to change in the future. The goal is to provide estimates of how temperature and rainfall in the greater Houston area will change over the coming decades due to anthropogenic emissions, and how these changes will impact building designs of the future.

Topic: The implications of Climate Change on the design and operations of buildings in Houston
Although there has been increasing attention within the HVAC Industry about Climate Change, opinions are still divided as to the appropriate response, with some focused on resiliency during more extreme climate events, and others on improving building energy efficiency to counteract the gradual increase in global temperatures. Although there’s general agreement that buildings should be designed with the future weather in mind, design practices still rely on historical weather data from the past. The presenter will describe the historical trends in weather conditions in the Houston area over the past 30 years, as well as the projected trends over the next 50 years, and share his experiences in creating future year weather files.

Topic: The Effect of Increasing Vegetation Cover on Energy Demand for Heating and Cooling Buildings in a Dense Mediterranean City
The study examines the effects of adding vegetation to a Tel Aviv neighborhood on the microclimate, and subsequently on electricity consumption for heating and cooling. Computer simulation was employed to generate modified weather files that account for urban effects in different building configurations. These files were then used as inputs for detailed computer simulation of building energy performance. Elevated night-time temperatures in the urban location increase summer cooling relative to the reference rural site, but reduce winter heating, resulting in a net decrease of 2-7% in overall electricity use for heating and cooling (depending on building characteristics). The reduction in the potential for cooling by night ventilation will increase the prevalence of air conditioning use and make buildings more vulnerable to potential loss of electric power during episodes of extreme heat. Implementing a strategy of extensive planting, so that a green surface fraction of 0.5 is obtained, results in a mean annual temperature reduction of about 0.3 °C and an energy saving relative to the current condition of about 2-3%.
Dr. Stephanie Taylor graduated from Harvard Medical School in Boston, Massachusetts, and practiced pediatric oncology and did research in cellular growth mechanisms for several decades. Alarmed by the high number of patients acquiring infections during their in-patient treatment, she became concerned that the hospital built-environment might play a role in patient outcomes. Realizing that she knew little about the design and management of buildings and mechanical systems, she returned to school to obtain a Master’s degree in Architecture. Dr. Taylor now works as an international consultant and research leader to better understand how the design and operation of hospitals, offices, schools and all occupied buildings can help people thrive, not merely survive. She has published in Nature, Science and other peer reviewed journals, is a Distinguished Lecturer for ASHRAE and a columnist for Engineered Systems magazine. She received the, “Women to Watch in the HVAC Industry” award in 2019. She is also a member of the ASHRAE Environmental Health Committee and the ASHRAE Epidemic Task Force.
Topic: The Healing Power of Indoor Air
We are currently living with tremendous uncertainty brought about by a mutated virus of the familiar Coronavirus family. Many unanswered questions about COVID-19 disease transmission, mortality rates and our own immune response have resulted in fear, confusion and a sense of helplessness in many of us. Thankfully, we have a solid foundation of scientific data from studies in microbiology, medicine and the indoor environment that can guide our management of buildings so that they are true shelters.
Dr. Taylor will present studies on building interventions that optimize the health of human occupants and decrease the threat of microbial pathogens such as COVID-19. Communication between medical and building professionals, such as in this webinar, along with your input will help us fight back and regain our footing. Attend this webinar to learn about the power of the indoor environment to keep us safe and healthy during COVID-19 and beyond.

Topic: Utilizing Machine Learning and Cloud Computing to Automate and Speed up Daylighting Simulations.
Architects and engineers often investigate the daylighting performance of hundreds of design solutions and configurations to ensure an energy-efficient solution for their designs. To shorten the time required for daylighting simulations, architects usually reduce the number of variables or parameters of the building and facade design. This practice usually results in the elimination of design variables that could contribute to an energy-optimized design configuration. Therefore, this research aims to incorporate a machine learning algorithm that requires the execution of only a small subset of simulations to predict the performance of thousands of different configurations, therefore speeding up the simulations process. Incorporating such an algorithm with the parallel computing environment provides almost-instant feedback.
