Part 1: The Workshop
DaVita World Headquarters: 16th St.
Denver, CO 80202
1:00 pm – 3:00 pm MT
This talk was co-presented with Tom Hootman (MKK Consulting Engineers), and Dane Sanders (Clanton & Associates).
The significance and urgency of proper daylighting in buildings
Through graphics and animations generated from innovative simulation tools, presenters discussed the strengths and limitations of the new metrics promoted in LEED v4. Presenters went beyond reciting formulas to help participants define these metrics in meaningful terms they can visualize, understand and use in their every-day practice.
The Following Issues were explored:
Workplane: LEED BD+C v4 EQc7 requires you to only measure light at the workplane. What are the implications of only looking at lightat a horizontal plane 30″ above the floor? Presenters discussed the benefits of analyzing light in other critical areas, such as the ceiling and wall, and the issues of glare in these contexts.
- Annual Climate: The nuances of daylight given subtle changes in climate are not obvious. As demonstrated by LEED v4’s vastly improved precision of climate, presenters illustrated how different regions can impact the same design in profoundly different ways. In addition, novel concepts using sunrise and sunsets, ranges of climate that go beyond LEED v4 will be presented.
- Dynamic Blinds
:Unknownto many, LEED v4 has a model of occupant behavior for opening and closing the blinds, depending on daylight position and availability which both directly and indirectlyaffect the scores. Presenters discussed the assumptions built into the model, how realistic they are and how they compare with motorized automated blinds.
- The ‘Goodness’ of Quantification
:LEEDv4 has several cut-offs built into its calculations, such as only scoring positively when exactly half or more of the year exceeds a threshold. Presenters illustrated cases where these boundaries meet, exceed, or contradict design expectations.
Part 2: The Tour
Museum of Contemporary Art
1485 Delgany St.
Denver, CO 80202
3:00 pm – 4:00 pm MT
This tour led by Glaser, Hootman, and Sanders, and highlighted the Denver Museum of Contemporary Art’s daylighting strategies.
