Breaking the Cost Barrier
Hours: 3?
Express Program: NOT YET


Learning Objectives:

Participants will be able to describe what drives a peak heating and cooling load, and how those related to annual energy consumption. Participants will be able to explain the impact that envelope performance and amount of glass have on HVAC system sizing and first cost. Participants will be able to dispel the myth that quality design, superior energy performance (NZE), occupant satisfaction and low first costs are incompatible goals through real examples.

Course Description:

Like it or not, money talks. In pursuing high performance, there are many potential financial pitfalls. For example, the benefit of high performance envelope strategies are often washed out with overly-conservative HVAC sizing; using rules of thumb for system sizing makes it look like achieving targets are out of reach. And, designers often are not aware of the impact of their design decisions on loads, HVAC system design, and construction cost. So, improper investments are made that tip the balance away from achieving both energy and construction cost goals. In other words, using data to question and inform optimal design decisions is essential to achieve true high performance without driving up construction cost. The high performance goals extend beyond energy to address indoor environmental quality including thermal comfort and daylighting. The experts listed below, will guide you through these challenges, and approaches to deal with them, using real world experiences and case studies to showcase each scenario. But, beyond your typical training, this session directly engages the attendees in a game that simulates the design decisions encountered on actual projects. In the game, teams compete to achieve high performance goals, while breaking the cost barrier. You will be surprised at what you learn through this hands-on process, and how much fun you have doing it!
