SimpleHouseRSla¶
The simple house is a one-zone residential building.
Building and thermal zones¶
The entire house is modeled with a single thermal zone. The parameters of the envelope are typical from a not-very well insulated american house and are taken from the modelica buildings library. The building has no cooling system.
Thermal systems¶
A water to water heat pump is connected to a simple room model with hydronic underfloor heating. A schematic picture of the equipment is given in the following image:
Electrical systems¶
The site incorporates a photovoltaic installation.

Evaluation scenario¶
The evaluation scenario for the SimpleHouseSlab-v0 model consists of a control from January to April with the objective of minimizing the power demand, while keeping the zone temperatures between 19 and 24°C. For this goal, the tracked KPIs are the average power demand, and the average temperature deviation and total temperature violations with respect to the interval [19, 24].
