Building performance refers to how well a building works to keep people inside comfortable and safe. It's like your new toy house that your parents bought for you, and you want it to be perfect. Now, imagine that this toy house needs to keep you warm in the winter and cool in the summer, and it needs to be strong enough to withstand weather conditions like rain, wind, and snow.
When people design a building, they use specific materials and designs to make sure it is strong and sturdy, and also to keep the temperature inside the building comfortable. So, just like your toy house has walls, a roof, and windows, real buildings have these too, but with special features to make them work better. For example, the walls might be made of special insulation to keep the heat inside during the winter, and the windows might be double-paned to keep the cold air out.
Once the building is built, people need to make sure it is working correctly, just like how you check to make sure your toy house is standing up correctly and all pieces are in the right place. They measure things like the temperature, humidity, and air quality inside the building to make sure it is healthy and comfortable for people to be inside.
If the building isn't working properly, there are things that can be done to fix it, just like if your toy house needs some repair or parts replaced. This might involve changing how the heating or cooling systems work, or adding insulation or better windows.
Overall, building performance is about making sure that buildings are safe, healthy, and comfortable for people to be inside. Just like your toy house, we want it to be perfect and a great place to be!
