From the chart by understanding yellow as mean temperature, green below as average low, green above as average high,we can see basically April, May and October are the three months with more comfortable temperature range, which June to September have the warmer temperature and January to March, November to December has a cooler weather range in Houston

This chart shows the temperature in different depth. My building is placing on grade so just by concentrating on the yellow line, we can see from May to September has the higher temperature and the others lower. It also can be reflected on the graph on the left.

This chart shows the dry-bulb temperature which is the temperature of air measured by a thermometer freely exposed to the air but shielded from radiation and moisture. It is usually thought of as air temperature, and it is the true thermodynamic temperature.The red in the chart shows that during May through August from 6am to Midnight have the higher dry bulb temperature throughout the year

Wet Bulb temperature is a type of temperature measurement that reflects the physical properties of a system with a mixture of a gas and a vapor, usually air and water vapor.It is the temperature one feels when one's skin is wet and is exposed to moving air. Here we can compare to the dry bulb temperature, (showns in red) June and July from 6am to 6 pm have the warmer wet bulb temperature throughout the year

Wind Speed is also an important factor, from here we can see throughout the year wind speed is mostly around 5-10 mph (shown in light blue) and during May to December, it will get more windy in the morning and at night. (shown in dark blue)

In this graph, red means 60%-80% humidity. So we can see that Houston is mostly humid throughout the whole year.


Understanding the comfort level by reading the red as uncomfortable percentage and green as comfortable percentage. From the explaination below we can see how the comfortable level bumped up gradually by adding different design strategy.
Without any sun shading for the buidling, the comfort level is basically close to 0%

Having cooling system can help to bring the comfort level straightly up to 42%

By adding extra dehumidification, comfort level bumps up to 53%

Putting passive solar system and internal heat gain, comfort level goes up to 84%

The most desire environment, adding heating system to the system for cold weather situation, makes the comfort level up to 100%
