Tip: How to select a future weather file for building performance simulations

For building performance modelers, we can no longer rely on historical data for building energy modeling. We used historical typical meteorological year (TMY) files in the past today, we must opt for future weather files and prepare our buildings🏬 to be 🌡️ climate-proof. I strongly recommend using future weather 📂 files to

Impact of climate change on nearly zero-energy dwelling in a temperate climate: Time-integrated discomfort, HVAC energy performance, and GHG emissions

This paper projects the current and future climate scenarios' impacts on a nearly zero-energy dwelling in Brussels. Initially, a time-integrated discomfort assessment is carried out for the base case without any active cooling system. It is found that overheating risk will increase up to 528%, whereas the overcooling risk

Tip: HDD and CDD indicators are better than Köppen–Geiger climate classification

The Köppen-Geiger 🌡️climate classification is based on 🥬 ground cover vegetation, for which the 🌧️ rain is the most important parameter for clustering. It is not the best adapted to energy use evaluation in 🏬 buildings. I strongly recommend using HDD and CDD indicators and future weather 📂 files to better (more accurately) 🔣 characterize
