In this chapter, you ll learn how to use some of the sustainable design concepts that we discussed in previous chapters with BIM models. We will look at some real-world applications and examples of design strategies and show how you can apply them by using today s BIM technology. In this chapter, we ll discuss building orientation, building massing, and daylighting.
Before we delve into discussing any specific workflows involving BIM and sustainable design, it is important to recognize that many strategies are both cumulative and interdependent. Adding some strategies on top of others can have a compounding benefit; stopping too early may have only increased first cost with little long-term benefit. The same is true regarding interdependence. Take the example of building orientation, glazing, and daylighting. Rotating your building in the proper direction, using the right glass in the correct amount and location, and integrating sun shading into the project to optimize the use of natural light all build on each other. The amount of usable daylight that you might capture will be greatly reduced with highly reflective glass or if the building faces the wrong orientation. The appropriateness of any of these individual strategies and the benefits are dependent on building type and climate.
Figure 5.1 shows the cumulative effects different energy efficiency measures can have on a building. The first cost for the building is the line with diamonds...
