Climate Consultant is a graphic-based computer programme that helps users, including architects and builders, understand their local climate. It achieves this by utilising free EPW format data provided by the US Department of Energy, which encompasses climate information for numerous locations worldwide. 

It converts this data into various graphic displays to highlight climate characteristics and their impact on building design, aiming to promote energy-efficient, sustainable buildings tailored to specific locations. 

Its advanced Psychrometric Chart plots temperature and humidity for each hour of the year, identifying effective passive heating and cooling strategies and providing tailored Design Guidelines for any location.
