“A room is not a room without natural light. Natural light gives the time of day and allows the mood of the seasons to enter.”
— architect Louis Kahn
Proper lighting not only provides visual information (you can see where you’re walking) but also constitutes a powerful modulator of our circadian rhythm and many nonvisual functions, including the state of alertness, mental focus and cognitive performance. So, when designing an animal hospital, how can we reap the benefits that proper lighting can offer? The answer is an art and practice called daylighting.
Daylighting is an architectural design strategy using natural daylight to provide or enhance a building’s interior lighting. Particular attention is given to daylighting while designing a building when the aim is to maximize visual comfort or to reduce energy use.
The amount of daylight received in an interior space can be determined by measuring illuminance on a grid or undertaking a daylight factor calculation. Architects and engineers can provide valuable expertise when designing a building to achieve maximum daylighting benefits, but don’t neglect a cost analysis to weigh the value of any daylighting feature against its installed cost.
I would attempt to put in as many windows in as many rooms as you can that call for it. Some rooms you don’t want light in, like rooms that use scopes. And, in the back of my mind, I’m also thinking, is this a south- or west-facing window, so we need to worry about glare at certain times and certain seasons?
I went to a hospital once with a big bowl of sunglasses of all kinds outside the surgery room. The doctor told me, “You may want to put on sunglasses.” I figured I was fine. I walked in there and found a skylight over the surgery, with a blinding effect from all the glare off the white walls and gleaming stainless steel. Make sure you can control the light in rooms like that, like this one.
Energizing daylight comes to healthy and recovering pets thanks to big windows facing directly from the play area into the kennels.
