1. A method for generating, in real time, an interactive three-dimensional quantitative thermal heat flow mapping of an environment using a user equipment, the method comprising:
receiving input data at the user equipment, the input data representing one or more datum positions in a real time image of the environment, wherein the real time image of the environment is generated using an imaging module of the user equipment;
determining the relative position and/or orientation of the user equipment relative to the one or more datum positions of the environment to define the one or more datum positions with respect to the real time image of the environment;
generating a three-dimensional representation of the environment, the representation comprising multiple surfaces defining respective boundaries of the environment, wherein the boundaries of the environment are established using the one or more datum positions;
generating a thermal image representing a surface temperature at multiple points on respective ones of the surfaces of the environment within the three-dimensional representation;
determining a measure for an ambient temperature within the environment;
determining respective measures for incident radiant temperature of the surfaces;
determining respective measures for the emissivity of the surfaces;
providing a measure of temperature outside of a surface;
calculating, at each of the multiple points, a value for the instantaneous heat flow per unit area using the measures for surface temperature, ambient temperature within the environment and incident radiant temperature of the surfaces; and
using the values for the instantaneous heat flow per unit area, and the measure of temperature outside of a surface, calculating respective measures for thermal transmittance at the multiple points.
