4. Average temperature(the average low at 1°C in winter
and only 23°C in summer).

5. Max and Min temperature

6. Wind analysis(wind temp 10 to 15,relative humidity 50%to 60%)

7. Winds tend to be slightly stronger in winter but the most constant
weather pattern would be rainfall. Snow is possible but doesn’t occur
very often.

8. Rainfall(monthly analysis)
On average Belgium gets more rainfall than the UK and slightly less than the Netherlands, the
rainiest months are July (mid-summer) and December (early winter). The month with the least
rain in Brussels is actually April (mid-spring) – but still carry a fold-up with you just in case!
Despite so much rain, humidity is moderate (around 50%).

15. Monthly analysis

18. Analysis Diurnal temperature data shows daily cycles of
temperature and radiation on the site
winter months, the temperature range is well below the
comfort zone, so we’ll likely need to use mechanical heating
(though solar radiation is high during the day). During the
summer months the temperature ranges are close to the
comfort zone so we’ll likely be able to condition the building
passively (although there is a larger temperature swing from
night to day).

22. AVERAGE WEATHER IN BRUSSELS, BELGIUM
•Brussels has a temperate climate with four seasons spanning the whole year.
Temperatures are relatively mild during the whole year. On average Belgium gets more
rainfall than the UK and slightly less than the Netherlands, the rainiest months are July
(mid-summer) and December (early winter). The month with the least rain in Brussels is
April (spring). Despite so much rain, humidity is moderate (around 50%).
What's the best time to travel to Brussels in Belgium? Here are some facts:
The months June, July, August and September have a nice average temperature.
•On average, the warmest month is August.
•On average, the coolest month is January.
•July is the wettest month.
•May is the driest month.

23. Daylight factor
The concept of Daylight Factor (DF) was developed in the United
Kingdom in the early 20th century. Daylight Factor is a ratio that
represents the amount of illumination available indoors relative
to the illumination present outdoors at the same time under
overcast skies. Daylight Factor is typically calculated by dividing
the horizontal work plane illumination indoors by the horizontal
illumination on the roof of the building being tested and then
multiplying by 100.

24. Process to calculate the Daylight factor
Prepare geometry(which is two sotrey in this
case)
Set site location(which is Belgium Brussels)
Set material properties(default materials)
Setup Grid
Perform Daylight factor
