Introduction to ASUS Main focus: Improving the human thermal comfort with the help of sustainable urban planning in New Aswan, Egypt ASWAN: Hot arid desert climate (Köppen BWh) - Analysis of local climate change (COSMO-CLM) - Analysis of meteorological variables for the campus of New Aswan University (case study) and all of New Aswan source: google ( ENVI-met , MUKLIMO_3 ) - Scenarios for adaptation and mitigation to local climate change will be designed and evaluated - Options for decreasing the energy demand of buildings will be considered ( DesignBuilder ) source: wikipedia 06.08.2018 2
COSMO-CLM simulations COSMO-CLM - Regional climate model - Developed by CLM-Community (Germany) - Spatial resolution: 1-50km (here: 12.5km) Results are well within the range of the IPCC Fifth Assessment Report AR5 in 2014 06.08.2018 3
Extreme Indices SU35/40 -> Day where T max > 35°C / 40°C TR25/30 -> Night where T min > 25°C / 30°C Warm Spell -> At least 6 consecutive days where T max > 90th percentile 06.08.2018 4
DesignBuilder simulations (set up) source: google DesignBuilder - Single building scale - Developed by DesignBuilder Software Ltd (England) - EnergyPlus simulations for energy consumption (e.g. cooling energy) 06.08.2018 5
DesignBuilder simulations (first results) 4 3 1 2 Cooling setpoint temperature: 24°C Masterplan for the campus of the New Aswan University 06.08.2018 6 6
ENVI-met simulations (set up) ENVI-met - Resolution: 0.5-10m (here: 2m) - Microscale model for calculation of human thermal comfort indices (e.g. PET) - Developed by Prof. Dr. Michael Bruse (Germany) Base case P hysiologically E quivalent T emperature PET [°C] combines T, RH, wind and solar radiation to form a thermal index which is comparable to indoor conditions. A PET of 20°C indicates that the outdoor thermal conditions feel like a room with 20°C would feel. First test-scenario : 100% green roof & loamy soil (contains more water) in one area 06.08.2018 7
ENVI-met simulations (first results) PET [1.1m] at 11 am Temperature [1.1m] at 11 am Green roof - Base case Green roof - Base case - Green roofs bring cooling of about 1K at 11 am - The PET can be reduced by nearly 2.5K close to the buildings 06.08.2018 8
MUKLIMO_3 simulations (set up) ~ 11 km ~ 9 km source: google M ikroskaliges U rbanes KLI ma MO dell in 3 Dimensionen - Resolution: 50-200m (here: 100m) - Developed by the DWD (German Weather Service) - Simulates meteorological variables (e.g. 2m-temperature) on the basis of landuse data , elevation and meteorological conditions (temperature, relative humidity, wind speed/direction, cloud cover) on a diurnal scale 06.08.2018 9
MUKLIMO_3 simulations (first results) New Aswan Simulation date: 05.07.2017 T max = 46.4°C T mean = 33.1°C T min = 19.2 °C Assumed Scenario: All buildings have 50% of roof covered by vegetation (base: 0%). All surfaces (roofs, walls, pavement) have an albedo of 0.5 (base: 0.3) 06.08.2018 10
Outlook - Create scenarios to improve the micro climate in New Aswan ( case study: campus of the New Aswan University ) - Investigate the effect of scenarios on energy consumption ( case study: campus of the New Aswan University ) - Implement the scenarios to all of New Aswan - Investigate the master plan for New Aswan ( keyword: big park in the southeast ) - Contact with stakeholders in New Aswan through partners at Aswan University - Create guidelines for other Egyptian new towns in similar climates -> Possible next project : Research towns in other climates 06.08.2018 11
