Dream Home Interiors Nightlight Schedule

In Part 1, we were presented with a set of rules and restrictions for home interiors light in order
| To achieve home interiors light standards more suitable
to aging eyes (which the literature allows begin to need extra home light in their
40s) | |||||
To translate these new home light design standards into
numerical targets of common metrics readily identifiable in the retail home
light marketplace
|
Comment: OK, let’s try on an example.
| A bedroom has an ambient fc target value of 40,
i.e., 40 lm/ft2. That’s a given in AG’s book. | |||||||||||||||
| The bedroom we’re targeting in this example is, say,
200 ft2 in floor surface area. | |||||||||||||||
| 40 lm/ft2 multiplied by 200 ft2
= 800 l, our lumen target. | |||||||||||||||
The author is not immediately, if at all, interested
in that with which the space gets lighted, that is, not materials at least
in so far as luminaires are concerned, but methods are entirely another
matter of keen interest to Before The Architect and would usually be
extensively specified and guidelined -
|
Comment: Again, Delores, it’s the lumen number for a space coming from the Rules that bridges the gap between your home light interests and intentions and the folks who know a lot about home light but not a lot about you
Comment: Told you mathphobes so: multiply 40, 70, or 100 times the square feet of respectively lighted surface area, and take it to a home light professional along with the AG’s rules – The Basics and The Math.
This Nightlight schedule was presented with extensive notes, including
| Selected types of luminaires are indicated in order to
keep perspective broad | |
| Certain materials are preferred, e.g., brilliant
reflectors to get the maximum illuminance out of CFLs | |
| Rules of artificial, or mechanical, illuminance design
are repeated as a fall-back reference | |
| Methods are highlighted, e.g., layering, dimmers,
under-cabinet skirting, etc. | |
| Materials are recapped, e.g., pendant, lantern, cove,
etc. | |
| Light quality hurdles are indicated | |
| Site-specific concerns about home light in cooler spaces, potentially hazardous glare, cold-weather fluorescent materials and methods, etc. get prominence |
The Schedule and related notes get translated in the Electrical Plans in plan view, as excerpted below
| This is not about
beating a dead horse: texted table, extensive notes, now a floor plans expression of
electrical wiring including
home light, whew | |||||
This is about taking
the wiggle-room out of electrical wiring and home light design in application
