Suggestions regarding energy loads
Suggested techniques
Average temperature(the average low at 1°C in winter and only 23°C in summer).
Max and Min temperature
Wind analysis(wind temp 10 to 15,relative humidity 50%to 60%)
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.
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%).

Monthly analysis
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).

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.
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.
Process to calculate the Daylight factorPrepare geometry(which is two sotrey in this case)Set site location(which is Belgium Brussels)Set material properties(default materials)Setup GridPerform Daylight factor
