accim 0.7.3

Transforms PMV-based into adaptive setpoint temperature EnergyPlus building energy models

ACCIM stands for Adaptive Comfort Control Implemented Model.

In research terms, this is a proposal for a paradigm shift, from using fixed PMV-based to adaptive setpoint temperatures, based on adaptive thermal comfort algorithms and it has been widely studied and published on scientific research journals (for more information, refer to https://orcid.org/0000-0002-3080-0821).

In terms of code, this is a python package that transforms fixed setpoint temperature building energy models into adaptive setpoint temperature energy models by adding the Adaptive Comfort Control Implementation Script (ACCIS). This package has been developed to be used in EnergyPlus building energy performance simulations.

The figure below clearly explains the aim of adaptive setpoint temperatures: introducing hourly temperature values into the adaptive comfort zone. On the left column, you can see the simulation results of a naturally ventilated building, while on the right column, the same building in mixed-mode operation with adaptive setpoint temperatures.

2. How to use

2.0 Requirements

To use accim, the following must be installed:

• Python 3.9
• EnergyPlus (any version between 9.1 and 23.1 those included)

2.1 Installation

First of all, you need to install the package:

pip install accim

2.2 Usage

2.2.1 Transforming PMV-based into adaptive setpoint temperatures

This is a very brief explanation of the usage. Therefore, if you don't get the results you expected or get some error, I would recommend reading the 'Detailed use' section at the documentation in the link https://accim.readthedocs.io/en/master/

accim will take as input IDF files those located at the same path as the script. You only need to run the following code:

2.2.1.1 Short version

from accim.sim import accis
accis.addAccis()

Once you run this code, you will be asked to enter some information at the terminal or python console to generate the output IDF files.

2.2.1.2 Longer version

from accim.sim import accis
accis.addAccis(
