## Tutorial Introduction

The goal of this exercise is to look through the process of running a daylight and energy analysis through Honeybee. This example refers to a shoebox geometry and highlights all the important parameters both for setting up the analysis geometry, but also for running the different simulations. The techniques discussed in this example can later be applied to simulations for different design models or larger building groups.

#### Exercise Description

Rhino geometry of the tutorial - Overview

Let’s assume an apartment which is on the ground floor of a 2-storeys building. It has a rectangular plan of 10m*10m and it has a height of 3m.

The apartment has an entrance from the road with an opaque wooden door and has also one operable window facing the street. The window is shaded with wooden horizontal louvres. On the left and right side there are adjacent apartments, but on the back side it is not neighboring any other apartment or building.

The exterior walls are made of concrete in light grey color. The slabs are also made of concrete and they are painted in white color on the bottom side (ceiling). On the top part (floor), they are covered by timber in a darker color. The interior walls are made of plywood and covered also in white paint.

Given that the example model refers to a small single-family apartment, we are going to assume that, on weekdays, it is mostly occupied during the afternoon hours, whereas, on weekends and holidays, it is occupied all day long.

Regarding the HVAC systems, we are going to assume that the apartment has only natural ventilation and no mechanical ventilation or heating/cooling at all.

#### Example file

In this tutorial, the detailed steps for the creation and running of the Honeybee simulation will be explained. You can download the files developed for this tutorial. However, to really understand how the script works, it is recommended to build it yourself.
