Daylighting, Modeling and Building Automation

This year, the National Passive Solar Conference, which is in its 38th year, will feature two broad themes that explore passive architecture and building technology – “Emerging Architecture & Passive Building Technology” and “Daylighting, Modeling & Building Automation.” Each track offers insight into state-of-the-art in solar and sustainable building research and practice.

Brief summary of results:

An investigation has been made of potential lighting electricity reductions and associated thermal impacts of replacing electric light with daylight admitted through rooftop glazing. Horizontal apertures on flat roof (skylights) and vertical apertures facing in two opposite directions (roof monitors) are examined in a prototype office building. A computer simulation tool that integrates lighting simulation and energy simulation called DIVA-for-Rhino has been used. Building operation costs are calculated as a function of aperture to floor area so that the optimum roof daylighting design could be identified. The results indicate that rooftop glazing contribute to savings in building operation if a modest amount of glazing is used in the roof. The design implications of the results are discussed and important parameters that influence the rooflit building operation costs will be outlined.

1:30-3:00 PM Forum – Solar Access & Zoning

Abstract: Architects choose how to incorporate sunlight into their designs, often for day-lighting or renewable energy. However, future access to the sun is often controlled by the decisions of other architects building on neighboring sites. Solar access zoning, one method of protecting solar rights, ensures that a building does not shade its neighbors for a specified time period each day. A solar envelope represents the largest volume that satisfies the conditions of solar access for the building’s neighbors. This does not imply that a building within the envelope’s spatial limitations is an energy-efficient design. Rather, when applied to adjacent lots, solar access zoning guarantees that each lot receives enough sunlight to take advantage of passive and active solar design strategies. The geometry of the solar envelope is relatively difficult to calculate; it depends both on spatial relationships between the sites, and on the daily and seasonal path of the sun. Solar envelopes can be constructed as physical models with a heliodon or generated by various digital tools. Each tool reflected the current technology of the time, and the progression of modeling environments has made many obsolete. As CAD has evolved into building information modeling (BIM) in the architecture profession, it is useful to consider the advantages of solar envelope generation within a BIM program. A plug-in to revit architecture (written in c# for the revit api) was developed to generate solar envelopes; the integration with BIM facilitates the analysis and use of solar envelopes in design.

3:30-5:00 PM Emerging Architecture Forum- The Mythic Modern: Mythology, Ecology and Technology…The Spirit of Place

This session explores less the technical “how” or the “what” about passive solar design, but more so the “why”. Why does solar architecture still drive the hearts and minds of our clientele and the population as a whole when it does so little of the heavy lifting? Why does the yearning for nature always overwhelm us more than the nuts and bolts, especially for winning commissions? How is it that the mythical aspect of the sun can command so much allure Where else can architects search for such powerfully persuasive poetics? The heart of the talk is that vanishing cultural poetics is a far greater cry for architects and without understanding the mythical modern aspects missing today, ideas like passive solar will fade into their own sunsets.
