How do you calculate solar orientation?
(How-To) Determine the Sun Path and Sun Angles for Your Location
- Look up your city’s latitude.
- Subtract your latitude from 90° to get your Equinox.
- Sun angle at summer solstice = Equinox + 23.5°
- Sun angle at winter solstice = Equinox — 23.5°
Can Google maps show sun path?
This app overlays a dynamic 2D Sun-path diagram on a Google Map. To move the sun-path diagram around, simply click and drag the location marker within the world map. It should be fast enough even on a phone or tablet to update in close to real time.
How does the sun’s path affect the design of our buildings?
Designing a building with the sun in mind can help reduce both heating and cooling loads. Sun shining into a building provides free heat and natural light. It can also create glare and, when the heat isn’t needed, discomfort and added demand for cooling.
How is Sunset angle calculated?
To calculate sunrise hour angle: Find the latitude and day of the year, n . Estimate the declination angle using the equation: δ = 23.45 * sin((284 + n) * 360/365) .
What is the best building orientation?
The best orientation for living areas is solar north; however, orientations of up to 15° west of north and 25° east of north still allow good passive sun access.
How do you orient a building for energy efficiency?
Buildings with a ‘rectangular form’ should ideally orient their longer axes towards north-south direction rather than east-west direction. Greater the perimeter to area ratio, greater is the heat gain of the building. Greater the perimeter to area ratio, greater is the heat gain of the building.
Is Google Earth Pro still free?
Google Earth Pro on desktop is now free and available to download for Windows, macOS, Android and Linux. Explore worldwide satellite imagery and 3D buildings and terrain for hundreds of cities.
How do you make a sun path diagram?
The Steps
- initial map.
- use Sun Calc to find your sun path.
- adjust to a generic date and time.
- locking layers can be quite useful.
- adjust the sun path image.
- the circle is the base for the sun path diagram.
- clipping masks.
- draw the sun angles.
How do you decide the orientation of a building?
The following factors affect the orientation of a building:
- Sun Path: The orientation of building should be fixed in such a way that the sunlight should enter all parts of the building through doors, windows, and ventilators.
- The direction of Road/Street:
- Surroundings:
- Wind Direction:
- Nature of Rainfall:
How do you determine the orientation of a building?
Compass. Of course, the easiest way to find out the direction of our life is to use a compass. Look at the needle, which always points to magnetic north, to find out the orientation of the building’s facades. It may be that none of the facades run parallel to a cardinal point.

What side of building gets most sun?
south side
You’ll get more sunshine
As the sun rises in the east and sets in the west, the south side of any house will see the most hours of sunlight during the day – especially in the Northern Hemisphere – so a south-facing garden takes advantage of this.
How do architects determine the orientation of a building?
While deciding the building orientation, one must also take into consideration the location of landscape feature in a plot, i.e. trees, planters, etc. which will affect the building depending on sun direction and sun path.
Why is Google Earth so out of date?
Why doesn’t Google Earth Update Continuously? As previously mentioned, Google Earth combines satellite images and aerial photographs. Both take time to obtain and implement, and aerial photos are relatively expensive. Google would have to constantly hire pilots traversing the globe to keep up with potential changes.
Is there a difference between Google Earth and Google Earth Pro?
Google Earth lets you print screen resolution images, whereas Google Earth Pro offers premium high-resolution photos. Google Earth requires you to manually geo-locate geographic information system (GIS) images, while Google Earth Pro helps you automatically find them.
How sun path diagram is used in architecture?
Sun-path is the apparent significant seasonal-and-hourly positional changes of the sun (and length of daylight) as the Earth rotates and orbits around the sun [1]. Understanding the sun path is essential in protecting the environment and saving energy through passive building design.
For what purpose sun path diagram is used in building planning?
Sun path diagrams can tell you a lot about how the sun will impact your site and building throughout the year. Stereographic sun path diagrams can be used to read the solar azimuth and altitude for a given location.
How do I orient my house to the sun?
Positioning Your Home
That means that whichever wall is facing south will receive the most sunlight. To maximize the sun use, place the longest side of your house facing south. Design this south facing wall with little to no jogs and offsets, which would increase shade on the south side and thus reduce light.
Does a north west facing house get sun?
Though a south facing garden will benefit from the afternoon sun, most of us aren’t even in our properties at that time of the day! North and north-west facing gardens can get the evening sunlight, and that is when the majority of us will utilise our gardens.
How can we design according to the sun?
Focus should be first on south facing windows which receive the most direct sunlight and second on east and west facing windows. North facing windows generally don’t need shading. External shading should be designed to let in the winter sun but shade the summer sun.
