1.2. Zigzag Planning for Wind Control

And also, you know, don’t have too many offsets you know here, this is like too many, so symmetrical but still it’s too many offsets in it but then either try to make more of a defined shape because that is where you can even have a diagonal bracings, you can have some kind of support system so, it will; it is at least bound to a; this plan should be square or rectangular, if it is rectangular then you need to have a kind of intermediate support systems into it.

In this section, the text suggests that when designing buildings, especially to control wind damage, it's important not to include too many offsets or irregular shapes. A building's design should aim for more defined shapes, such as square or rectangular forms. Rectangular buildings require additional support systems to remain stable. This approach helps ensure the structure can “brace” against the wind effectively.

Think of a kite: a simple shape, like a diamond, flies better in the wind than a complex, irregular one. Similarly, buildings with clear, defined shapes handle wind better because they can direct it away efficiently.

Now, asymmetric buildings with empty pockets are more vulnerable to damage because don’t leave these empty pockets, we tried to fill that and that is where these are more stable you know, the symmetric buildings are more stable.

Asymmetric buildings, which have irregular shapes or 'empty pockets,' are at a higher risk of wind damage. These empty areas can create weak points where wind pressure builds up, making the structure more prone to failure. In contrast, symmetric buildings avoid these vulnerabilities because they distribute wind forces evenly across the structure.

Imagine a child’s toy built from blocks: a symmetrical tower made of blocks is less likely to topple over if a gentle breeze hits it compared to an asymmetrical structure with gaps, which could easily fall.

The row house planning also creates wind tunnel effects because the moment your house is one step to another, next to the shore and then it channels the wind and that is where it can damage the edges of the walls or the corners.

Row house designs can inadvertently create 'wind tunnels' due to their alignment. When houses are lined up closely together, especially near the shore, they can channel wind through these gaps, intensifying wind speed. This effect can lead to significant damage, particularly at vulnerable edges and corners of the buildings.

Consider how two cars parked closely together can create a narrow passage for the wind between them; that wind often moves faster through the tight space. It's similar to how a row of houses can funnel wind and increase its strength, leading to potential damage.

So, that is where you can even you know, now even the zigzag planning avoid wind tunnel effect right, so how actually, you can actually see about, how you can actually, give a little bit of vastness and then reduce it so, the zigzag pattern as well can have some control, it depends on how you are actually orienting it and similarly, the long phase of the building facing the wind direction.

Zigzag planning in building design helps mitigate the wind tunnel effect by breaking up the flow of wind between structures. This pattern can create more space and reduce wind pressure on the buildings. The overall effectiveness of this design also depends on the orientation of the buildings relative to the wind direction.

Think of a winding road versus a straight one: cars on a straight road can encounter a sudden gust of wind, but on a winding road, the wind is less direct and thus has less impact on the vehicles. Similarly, zigzag buildings can disrupt wind flow and reduce damage.

In fact, if you ever visit in the coastal villages of Tamil Nadu and the coastal areas; most of the times your short phase is of the building is facing the wind direction and whereas, in horizontal phase because that is where they have less number of openings and either that, if they are facing that side and they will have less number of openings.

In coastal areas of Tamil Nadu, buildings are typically oriented such that their shorter sides face the wind to minimize exposure. This design strategy reduces the number of openings on the windward side, offering less area for wind to push against, which enhances overall stability.

Think of a shield; when facing strong winds, it is better to present the narrow edge to the oncoming gusts rather than the broad side. This is similar to how buildings are oriented to reduce wind impact on their structure.

In terms of quality control, it is also talks about the material, what are the ratios we have to include. So, when we say about do not use cement and sand to be less than 1.6 okay, 1:6, so for 1 cement and 6 part of the sand.

Quality control in building construction emphasizes the correct ratios of materials used for mortar and other mixes. For stability, it is recommended to maintain specific ratios, such as no less than a 1:6 mix of cement to sand. This ensures that the materials used have the necessary strength to withstand environmental conditions.

Consider baking; just as a cake requires the right proportions of flour to sugar to rise properly, buildings need the right mix of materials to remain strong and resilient against wind and other stressors.
