Exercise Explanation for Week 5
Overview of the Exercise
- The video aims to explain the exercise for week 5, starting from the previous class's task of identifying elements on a solar chart.
- Key components to identify include azimuth, solar height, solar time, and months of the year on the solar chart specific to the Dominican Republic (20°N).
Required Information
- Students must mark hours, months, azimuth angles (horizontal solar path), and solar heights indicated by yellow circles on the provided solar chart. This is essential for understanding how to locate times throughout the year.
- A resource was shared: gaisma.com provides stereographic charts with detailed information such as temperature, humidity, wind direction and speed, and solar radiation data. This aids in completing their exercises effectively.
Second Stage: Wind Functionality
Understanding Ventilation
- The second part involves analyzing how wind affects building design and orientation through a recorded video call discussion among teams. Each team should not exceed 8 minutes in their presentation.
- Emphasis is placed on utilizing wind effectively in architectural projects and understanding its impact on building shape and distribution within spaces.
Working with Plant Diagrams
Identifying Directions
- Students will receive a plant diagram where they need to identify cardinal directions (north, south, east, west) based on their chosen orientation for their project work. Each group can select different orientations for north based on their preferences.
- They are required to create sections from this plant diagram by determining where they will cut it for analysis in upcoming exercises discussed during lectures. This includes using Gaisma data alongside their findings from last week's exercise.
Diagram Details
- The provided diagrams include both a plant view and a section view; students must understand how these relate while working with them—one has a protractor while the other does not for clarity purposes in viewing sections cleanly.
- In working with these diagrams, students will identify azimuth angles horizontally in plants while assessing vertical shadow angles in sections as part of their analysis process moving forward into practical applications of this knowledge.
Understanding Solar Angles in Architecture
Identifying Solar Angles
- The speaker discusses identifying the horizontal solar angle (azimuth) using a plant layout.
- The vertical solar angle (solar altitude) is determined through a section view of the building.
Tools for Measurement
- A protractor is used to measure angles, focusing on yellow circles that indicate solar height.
- The largest circle represents 0 degrees, with subsequent circles indicating increments of 10 degrees up to 90 degrees, which signifies the sun's highest point.
Orientation and Positioning
- Emphasis is placed on positioning towards the south when measuring angles; this orientation is crucial for accurate calculations.
- The discussion includes cutting a section of a room facing south to analyze sunlight exposure effectively.
Analyzing Sun Path
- The sun rises in the east and sets in the west; understanding this path helps determine how sunlight enters through windows at different times of day.
- A specific point is chosen on the graph to represent solar data for October or February at 1 PM, illustrating consistent patterns across these months.
Calculating Solar Height and Azimuth
- At 1 PM during either month, the intersection of lines indicates an azimuth angle of 1 degree and a solar height of approximately 55 degrees.
- This measurement informs how sunlight will enter through windows based on their position relative to the calculated angles.
Shadow Analysis
- Without an overhang or eave, sunlight would penetrate directly into the room; however, shadows are created by architectural features like window ledges.
- Shadows are defined as areas where sunlight does not reach due to obstructions; understanding shadow length helps in designing spaces that maximize natural light while minimizing glare.
Practical Application
- Real-life scenarios are discussed where individuals experience direct sunlight entering their rooms based on window placement and time of day.
- Accurate measurements allow architects to predict how much light will enter spaces throughout different seasons and times, aiding in effective design strategies.
Conclusion: Importance of Solar Angle Calculation
- Understanding both azimuth and altitude angles allows architects to create designs that optimize natural lighting while considering seasonal changes.
Analysis of Ventilation and Solar Protection
Overview of the Exercise
- The exercise involves analyzing ventilation, photometry, and solar protection based on a specific plant model. Students will utilize a table to combine information regarding building orientation and its impact on design.
Lighting Analysis
- Students are instructed to conduct an analysis of lighting using a protractor, focusing on how sunlight enters the space. This includes determining necessary solar protection measures if excessive sunlight is identified.
Options for Solar Protection
- Various options for solar protection are discussed, including:
- Eaves or overhangs
- Solar screens (e.g., shades)
- Natural elements like plants that provide shade
Group Collaboration Task
- After completing the individual exercises, students will watch a video on natural ventilation analysis. They are required to have a recorded video call with their group via Teams to discuss how building shape and orientation affect natural ventilation quality.
Conclusion of Instructions
- The instructor hopes that all instructions are clear and encourages students to reach out if they have any questions about the tasks outlined.
