A Shadowy Sensation

In the 1950's Canisius House in Evanston, named after St. Peter Canisius
(1521-1597), opened as a residence for Jesuit authors. Today it is a
residence for priests who work at nearby Loyola Academy, and a guest house
for visiting clergy.

The elegant property underwent a major landscape renovation in 2013 -
refurbishing entry walks, gates, driveway, courtyard, walls, fencing,
gardens and fountain. New sitting areas were added as oases for quiet
meditation and small gatherings.

The outdoor lighting approach was conceived during the design and planning
phase as a key element to enable greater use of the space after dark. The
intent was to provide visiting guests with a feeling of comfort in an unfamiliar place, invite exploration of the grounds, and uplift
the spirit while embracing the natural attributes of the property.

Making the most of the prevalent mature trees, an all-over luminosity was
achieved using a moon-lighting technique that positions specially-engineered
LED fixtures high in the tree canopy to project shadows downward through the branches and leaves. The shadow patterns painted on the home's stucco walls, paving and lawn are "organic" yet dramatic - much like the effect of a
perigree full moon beaming through the trees. The color of the light (in the
cool range of 5500 Kelvin), concealment of fixtures, careful aiming and
shielding, as well as utilizing arborist best-practices in mounting the
fixtures are paramount with this technique.

In contrast to the cool moon-lighting, warm light (2700-3200 Kelvin) on the
house facade, stone pillars and other built elements, and neutral or white
light (4000-4500 Kelvin) on shrubs, trees, fountain, and other features
weaves a more complex and interesting composition.

The lighting designer/engineer utilizes a broad range of fixtures - varying
the wattage, controlling shielding and light spread, and juxtaposing shadow
with light within the framework of an all LED system which is powered by 1 -
15 amp circuit and can last up to 30 years with lamp changes once a decade.
New technologies , like the flush-mounted coin-sized pavement lights, are
employed to resolve practical and aesthetic challenges.
