INTRODUCTION

An alarming number of new buildings suffer from moisture and mold problems. The risk of failure is highest in—but not limited to—cold, temperate, warm-humid, and hot-humid climates. The debate on why some buildings fail and others do not, as well as who is responsible for these failures and how to fix them, rages on. Instead of being aired in architecture schools and at engineering society meetings, however, this debate goes on in courtrooms and mediation hearings, among highly paid expert witnesses and lawyers—not among people who should be preventing failures, but among those who are rewarded by their occurrence.

The building industry seems baffled about the prevalence of building failures. Many wonder why the rate of building failures is not declining despite better technology, increased training, and more sophisticated building systems. It is not due to indifference or ignorance. We know we can prevent buildings from failing because we can fix them once they do fail. The primary reason we are not coming to grips with this far-reaching problem is simple: the design professionals entrusted with building performance are not receiving adequate feedback on the performance of their previous buildings.

Without that feedback, we do not know why some buildings work well and others do not, despite being apparently designed the same way. Metrics may say that the industry did a good job, yet clients keep complaining about building failure and the construction litigation business keeps growing. Until architects and engineers receive better performance feedback, they will have neither the ability nor the incentive to change.
