Assignment 02: Architectural Climate Adaptation

Assignment #2.Part 1 - Climate / Resource Site Analysis Exercise

Climate Analysis ExerciseUnderstanding the climate of a given location is the first step to provide a relevant and adequate design solution.Understanding the available resources, opportunities and constraints is crucial to develop a responsible design.Using one of the free climate analysis software from the US Department of Energy (DoE) – Building Energy Software Tools Directory perform a thorough climate analysis for your groups project location below and compare it to the climate in New York.

Groups:1. Mumbai, India (Hot-Humid)2. Anchorage, AK (Cold)3. Cairo, Egypt, (Hot-Arid)4. Rome, Italy (Temperate)5. Hilo, HI (Hot-Humid)6. Quebec City, QC, Canada (Cold)7. Managua, Nicaragua ` (Hot Humid)8. Las Vegas, NV (Hot-Arid)9. Bilbao, Spain (Temperate)10. Kathmandu, Nepal (Temperate)11. Salvador, Brazil (Hot-Humid)

In graphical form present, at a minimum, the following data:- World Map and Country Map indication location of site.- Global Solar Radiation (Average per month in W/m2)- Wind Resources (prevailing direction for each season in hours/ year, average wind speeds in m/s, analyze with

Beaufort Wind Scale)- Monthly and Annual Total Rainfall (compare with NYC) - Temperature (Maximum, minimum and averages by month)- Relative Humidity (Monthly averages)- Passive Strategy Analysis (Assess benefits of thermal mass/ passive solar heating/ super insulation, solar shad-

ing, natural ventilation, evaporative cooling, etc) ( diagrams of the 8 most important design strategies, as per Cli -mate Consultant recommendation)

Format this information on 11x17 multipage pdf. 4 diagrams per page, and upload to dropbox by next Monday 11pm. Max. Filesize 10MB.

Step 1 – download software (Climate Consultant is a good one)http://apps1.eere.energy.gov/buildings/tools_directory/subjects.cfm/pagename=subjects/pagename_menu=other_applications/pagename_submenu=solar_climate_analysis

Step 2 – download climate data (from Energy Plus download the epw file for your location, NASA and wunderground for additional data if needed)NASA http://eosweb.larc.nasa.gov/cgi-bin/sse/sse.cgi?+s01#s01(click on either ‘Click on a desired map location’ or ‘Enter latitude and longitude’ – need to create an account)

Wunderground http://www.wunderground.com/NORMS/DisplayIntlNORMS.aspEnergy Plus http://apps1.eere.energy.gov/buildings/energyplus/cfm/weather_data.cfm

Step 3 – open the weather file in the climate analysis software you downloaded

Part 2A generic design for a small building is given to all groups. Each group is assigned one of the climates above. After the climate analysis, you will research the basic environmental attributes of the site and climate zone and learning about climate responsive design. Then each team will propose envelope modifications to the generic design in order to reduce its heating and/or cooling loads (passive design). Possible modifications are of course dependent on the climate zone and include but are not limited to building orientation, form, wall construction, fixed and movable shading devices, windows/skylights, vegetation.

In addition to these general principles each team is required to adopt and appropriately size at least one specific passive design strategy from the options listed below (please note that strategies can and should be combined, but sizing and calculation will only be required for one strategy)

Cold: a) Direct Gain b) Indirect Gain c) Isolated Gain Solar Heating Systems

Temperate: a) Direct Gain b) Indirect Gain c) Isolated Gain Solar Heating Systems or d) Cross Ventilation Passive Cooling System

Hot Arid: a) Evaporative Cool Tower, b) Stack Ventilation Passive Cooling Systems

Hot Humid: a) Cross Ventilation, b) Stack Ventilation Passive Cooling Systems
