The typical US household pays between 3 and 4% of the family’s income on heating and cooling. Single-family houses spend twice as much energy for heating as multi-family houses. In EU houses, heating and hot water alone account for 79% of total final energy use. Cooling is a comparatively small share of full final energy use, but demand from households and businesses such as the food industry is rising during the summer months. This trend is also linked to climate change and temperature increases.
We use TADA to estimate a building’s heating load. The dataset considered includes 538 records and the following features are provided for each record:
The rising demands for glass walls in hotels, airports, and commercial complexes have elevated indoor temperatures leading to higher demand for cooling systems. Advanced prediction of building cooling time and heating time can help engineers and architects design energy-efficient buildings. This type of cooling load and heating load modelling permits various ‘what-if’ scenarios without even laying the first stone. The impact of a bigger glass ceiling in an airport can be modelled in a few clicks, and the resulting cooling load estimated seamlessly.
It poses the following construction question:
Can the heating load of a building-to-be be estimated?
The TADA predictive models provide good results: an R2 of 99%, a MAPE of 5%, and a RMSE of 1,04 for a mean of 22,13. Effectively managing the thermal behaviors of a building is a complex process. These behaviors are expressed in a collection of thermal energy equations, which, once calculated, will not change over time for a building unless significant renovations are carried out.
TADA is a simple alternative to the use of these complex equations.
TADA has selected the following six main criteria out of the ten available in the dataset:
An R2 of 99% means that the predictions are very accurate. It is interesting to note that the building’s relative density is a significant criterion in TADA’s decision, before the window area with three times the weight in TADA’s decision.
In one week, architects gained significant support in their energy consumption estimates for buildings-to-be:
