FACADE ANALYSIS - GLARE IMPACT Project Date & Location // November 2015, Indianapolis, IN Project Description // Facade Analysis - Glare Impact The client requested us to do a facade analysis on the south face of the storefront. Analyzing the effects of solar radiation on the glazing. The analysis will determine the optimal glazing type for mitigating heat gain and glare for the store.

Hourly Average on the Project Site

The project is located in cool humid climate. It has 2957 heating degree days and 586 cooling degree days. In this area, temperatures are mostly below comfort zone (68°F-75°F). The temperatures are above the comfort zone during May to September, with the peak temperature closes to 100°F. The sky condition ranges from cloudy to clear sky, while the proportion between direct and diffuse radiation is almost equal. The overall available daylight is higher during the summer and it drops during the winter. Glare Analysis Legend Imperceptible Glare : <35% Perceptible Glare : 35% - 40% Disturbing Glare : 40% - 45% Intolerable Glare : >45%

Sun-Path Analysis

Glare Impact Analysis

To assess the impact of the facade orientation, the facade sun-path study was conducted to determine the impact of direct sun to the interior space of the store, see images below. Based on the study, the south facade will get direct sun along the year except during late afternoon on summer.

To determine the impact of the glare, two locations were assessed. Location 1 is from the center of the retail area on the front, and Location 2 is from the inside retail area. For outdoor trees, we modeled the trees without leaves during the winter season. As the results, two series of glare studies were produced.

The sun path result indicates that the potential glare could occur in the interior space. The impact of the surrounding trees would be assessed during glare study.

At Location 1, perceptible glare and disturbing glare occur at 11:00 am and 2:00 pm. At this area, the direct sun will affect the display table from 11:00 am to 2:00 pm. Deep direct sun penetrations will occur during winter season. The worst conditions occur on September 21st at 11:00 am and 2:00 pm and on December 21st at 2:00 pm. At the Location 2, there is no glare occurring per the glare study. There is minimum direct sun penetrating the area. Therefore, this area has no glare issue.

Building Analysis: The south face of the building looks toward the wetland and its natural beauty. Located on the south face of the building are the gift shop and cafÃ©/cafeteria space. These two spaces are one of the many attractions of the building and will be occupy by visitors every day. Unfortunately, the south face of the building will be having a lot of solar gain throughout the year, especially during winter solstice.

REDUCTION OF SOLAR RADIATION

Analysis Results: Three different shading strategies were implemented over the gift shop space. The shading device then was tested in autodesk ecotect to determine which shading device would reduce the most solar radiation into the space for the entire day. The results show that shading device 01 (overhang w/ horizontal fins) would reduce 46% of the solar radiation over the other two methods. Shading device 03 (vertical fins) is the worst method to implement with only 1% reduce of solar radiation.

[PERFORMATIVE Tectonics] West Face Horizontal Facade System

Column

The large facade is designed to be both a shading device and facade of the building. The west face of the building uses the horizontal louver pattern to block out the evening sun. While the south face uses of the building uses vertical louver to block out the afternoon sun.

The column is custom design specifically to span 100 feet from ground floor to roof at the highest point of the building to accommodate the design of the slanted roof.

Horizontal Louver

Operable Vertical Louver System

The designed and spacing of the horizontal louver system is to allow natural ventilation and natural sunlight into the main gallery space. Looking at the main entrance of the gallery space from the third floor.

This system is to allow natural ventilation from North East trade wind to cool the main gallery space.

DISSERTATION RESEARCH Evaluating the Impact of Future Weather on Building Energy Performance Climate change and building energy use:

DISSERTATION RESEARCH DOC 1 & 2 // Spring 2015 - Spring 2016 Project Committee: Wendy Meguro, Chairperson Eileen Peppard, MS Manfred Zapka, Ph. D., P.E. Climate Change According to IPCC predictions, the global temperature increase, by the end of the twenty-first century, will range from 1.1°C to 6.4°C. Future Weather File // Honolulu, Hawai’i Future weather file for present-day, 2050, and 2080 Building Energy Simulation

The main objective of this research is to introduce the use of future weather files for BES programs in order to assess current energy use and potential future performance for building improvements and new building designs. The CCWorldWeatherGen and Meteonorm use the existing EnergyPlus/Typical Meteorological Year 3 (EPW/TMY3) weather files to generate EPW/TMY2 future weather files for 2050 and 2080. These files will be used to identify and analyze the potential impacts the changing climate has on the annual energy use, heat gain, and end uses for the Frog building at the University of Hawai‘i at Manoa (UHM) Honolulu. The results of the study will provide the designers and building owners insight into future building performance and potential building improvements that can be implemented now.

The methodology of this research can be applied to studies that examine a number of building design features, including but not limited to thermal mass, window-to-wall ratio, glazing material, overhang shading, green roof systems, and natural ventilation strategies. With today’s emphasis on reducing building energy use and on sustainability, it is essential to understand how building envelopes will perform in the future.

Relative Humidity (%)

Trends in average global temperature changes show that the climate is undeniably warming. The Intergovernmental Panel on Climate Change (IPCC) predicts that global temperatures will increase by a range of 1.1°C to 6.4°C by the end of the twenty-first century. For tropical climate zones, increases in global temperatures cause increases in building heat gain, which lead to increases in annual cooling energy use and poorer thermal comfort. This project evaluates the impacts of future climate change on the HNEI Frog building’s energy performance to determine the most effective envelope design now and for the future. Three designs models were created and compared: the Current Design model, the ASHRAE 90.1-2010 Standard Design model, and the Proposed Design model. Using the climate change future weather data methodology, building energy use and cooling loads were compared for three time periods, present-day, 2050, and 2080, under the IPCC A2 emissions prediction scenario. The hypothesis was that the Proposed Design model, due to higher levels of insulation, would perform better than the Current Design in each time period, reducing annual energy use.

Recommendation Based on the sensitivity study, Solar Heat Gain Coefficient (SHGC) seem have the most impact in annual energy saving. Therefore, I would recommend more focus to be done in: • Window Glazing (Double-glazing, Low-E glass, etc) • Solar Heat Gain Coefficient Rating

Proposed Design Energy Model

Conclusion & Discussions According to the simulation results, the Proposed Design model used 0.09% more energy than the Current Design for the present-day time period and 0.12% more for the 2080 time period. In 2050, however, the Proposed Design used 0.16% less energy. These percentages show that the Proposed Design model’s higher insulation levels (R35 for wall and R-65 for roof) were largely counterproductive even though it was hypothesized that the higher levels would help reduce the energy use across all three periods. It is possible that the higher insulation levels cause the building to trap heat at night whereas the current building, with its lower insulation values, is better able to release heat. The trapped heat and radiation caused by direct and diffuse solar radiation transmitted during the day from the insulation and window conduction caused the HVAC system to use more energy to cool the building and adjust for thermal comfort. The results show that over-insulating a building might not be beneficial for hot and humid climate zones due to heat trapping and heat radiating indoors at night.
