The David & Lucile Packard Foundation headquarters isn't just a beautiful example of modern design, it is a leader in energy efficiency, known for being the largest net-zero energy certified . Figure 1: Energy use in the US. Efficient use of space is a good indicator of economical design. When designing a building with energy in mind, therefore, architects need to consider both operational and structural embodied energy, and the two are intertwined. " "But sustainable improvements cannot be achieved through energy-efficiency measures alone. Instead, it is essential to consider the building as a whole, and this fact becomes clear in this book, especially through the case studies. To test those trade-offs in practical systems, Mueller and Brown analyzed three types of long-span structures: an enclosed, trussed arch; a “PI” structure (resembling the Greek letter); and an “x-brace.” Figure 1 in the slideshow above shows diagrams of the three building types along with photos of representative buildings. It can be expressed as the ratio of "environmental cost" divided by "Benefit for Society" . The transition from embodied to operational energy efficiency is more gradual with the x-brace, as shown in the slideshow above. An excellent resource that we found for passive solar design in hot, humid climates is the Florida Solar Energy Center.
