Developed by Dr Andrew Marsh, this web app displays annual hourly weather or analysis data in a series of synchronised charts. It can read EnergyPlus weather data (EPW) as well as EnergyPlus output data files (CSV). As both these formats contain large amounts of hourly data, it lets you select which metrics to view and compare as well as the date range over which to render them. This tool is for education purpose only.
