Layer 2: Light Mapping Mood and Emotional Effect
Creating a light map of desired mood and emotion in a space can be as simple as identifying descriptive mood words for each space or area of a project. This “Mood Map” can be created by drawing borders to define spaces of unique use and labeling each with a few descriptive terms. Think in terms of the overarching project mood as well each individual space. Project goals may call for spaces to impart a variety of moods; calm, welcoming, relaxed, professional, sterile, cold, etc. The goal is to then translate these mood descriptors into various effects or characteristics of light. The mood descriptors will inform decisions about intensity, color, texture, shape and origin of the light.
As with each of the Five Layers, it is advisable to apply each light map as a separate sheet of translucent velum or trace paper over the previous Light Maps in a stacking manner, so a designer can see where different lighting goals
overlap and support one-another.
Layers 3, 4 and 5: Light Mapping Visual Interest, Architectural Definition and Task Lighting
Once Light Maps have been created to successfully represent choreography and mood, the Light Map process is implemented for the remainder of the lighting thought layers. The third, fourth and fifth layers identified in the Five Layer Process should ideally be studied and rendered onto a light map individually. As a designer gains experience with the processes and tools, it may become second nature to tackle many layers at once.
However the process is articulated, the discipline is always focused on the
two core habits of visualizing lighted surfaces and objects - not luminaires and lamps - and drawing light to create visual representations of concepts. The Light Map process can be implemented many different ways, but the final result should be a visual representation of a project showing all of the light that will be added.
A well-executed Light Map process will create a visual road map to which
lamps, luminaires, controls and other lighting solutions can be easily applied to “solve” the desired lighting events. Before moving on, take time to review all of the aspects of the project program and whether they have been thoroughly addressed by these concept and graphic processes. Effort spent on the Light Map process will pay off in spades as design development rapidly moves into the “solution” phase of lighting calculations and equipment selection and placement.

The goal of the light map is to communicate ideas to others and to create a visual map of light that will help to make luminaire decisions easier. If the light map is thorough, with bold, clear graphics to represent light, it sets the designer up nicely to move forward and make quick work of laying out the luminaires that will create the lighting events.
