    • Get activity schedules in the epJSON format

Usage

NCM

Tools for analysing the National Calculation Methodology (NCM) database, tested primarily on data related to English dwellings.

[!TIP] To access the NCM database, the NCM modules depend on pyodbc, which in turn depends on an ODBC driver and driver manager for Microsoft Access. See pyodbc's installation guide for details.

Get activity schedules in the epJSON format

The aark.ncm.sched module provides functions for extracting NCM activity schedules and converting them into the epJSON format for EnergyPlus. In particular, the aark.ncm.sched.get_scheds function takes a sequence of NCM room names, a sequence of NCM schedule categories and a pyodbc.Cursor object for the NCM activity database, and returns an epJSON of schedule objects ready for EnergyPlus simulations.

[!IMPORTANT] This module currently has the following caveats:

• A non-leap year is assumed.
• Other gains schedules are not converted.

For instance, the following script retrieves the occupancy and heating set point schedules for the bedroom and the lounge.

import pyodbc

import aark.ncm.sched


room_names = ["Dwell_DomBed", "Dwell_DomLounge"]
sched_categories = ["OCCUPANCY_SCH", "HEAT_SET_SCH"]

with pyodbc.connect(
    Driver="Microsoft Access Driver (*.mdb, *.accdb)", DBQ="/path/to/the/database"
) as con:
    cur = con.cursor()

    sched_epjson = aark.ncm.sched.get_scheds(
        room_names=room_names, sched_categories=sched_categories, cursor=cur
    )

The sched_epjson variable contains the following epJSON of schedule objects.
