Dataset of the EnergyPlus model used in the assessment of natural ventilation potential through building simulation

The data set compiled in this file refers to the Multizone EnergyPlus model, used in the investigations of the research article entitled "Natural ventilation potential from weather analyses and building simulation". The technical information regarding the model has been grouped into tables, which include: the general simulation settings, the properties of the building materials, the Airflow Network opening settings used in the annual investigation, in addition to the controls established in the Energy Management System (EMS) for hybrid ventilation system operation. The user behaviour, regarding the living and bedrooms occupancy schedule, is also presented in a graph. This data set is made available to the public to clarify details of the EnergyPlus model and how the hybrid operation was defined. In this way, other researchers can perform an extended analysis of the information.

Value of the Data
• The detailed data related to the EnergyPlus model guarantees a better and deeper understanding of the building addressed in the research paper [1] , grounding the study developed and providing more information to aid in reading the paper. • Both building modelling and simulation are performed using EnergyPlus software. Different configurations/ simulation techniques could be employed based on this available data, so different studies might be compared. • The data presented in this article can assist designers and researchers who deal with the modelling of naturally ventilated buildings, especially with Airflow Network and multizone approach. • The use of Energy Management System (EMS) to model hybrid ventilation operation could be adopted as a reference for further research on naturally ventilated buildings.

Data Description
The data in this article present the input data regarding the EnergyPlus model used at the investigations addressed in the research paper. General simulation settings are summarised in Table 1 , while the building materials properties are listed in Table 2 . Table 3 shows the Airflow Network opening settings used in the annual investigation. Finally, the occupancy schedule, which specifies when the living and bedrooms were occupied, as well as its respective number of people, can be seen in Fig. 1 .
The model set up is based on consolidated practices used in studies involving INES' experimental houses, and therefore does not use the EnergyPlus database. Since they are originally  5, 6.21, 9.3, 12.99, 16.28, 18.27,18.43, 16.69, 13.55, 9.86, 6.58, 4.62 Time steps per hour 6 unoccupied, a classic family occupancy schedule was established, which would represent an extreme/worse possible scenario. Besides, the EnergyPlus input data files (.idf) are available for download in the Mendeley repository [2] , and the link can be found in the Specifications table/ Data accessibility. The files supplied include: the calibration (a) and the annual analysis (b) models, which are summarized in Table 1 .

Experimental Design, Materials and Methods
The controls developed in the Energy Management System (EMS) object for the consolidation of the hybrid behaviour at the annual analyses are presented below. The operation mode was adopted in all occupied zones, exemplified here by the living room zone.
The set up enables the following changes: triggering the thermal load calculation at a temperature different from the thermostat; deactivation of the thermal load calculation only after occupancy in a room is null; hybrid control, where the local thermal prognosis is not allowed to occur together with the window opening for natural ventilation in the same time step.
