G03 - Breaking the Cost Barrier Thru Data and Design

Abstract Text:

Like it or not, money talks. Attractive first cost is often the only way to achieve high performance. But in pursuing high performance, there are many current challenges to this first cost approach. For example, the benefit of high performance strategies are often washed out with over-conservative HVAC sizing; out-of-date methods for calculating occupancy make it look like achieving targets for increased ventilation to improve cognitive function requires heavy oversizing that are cost prohibitive; small enough HVAC units aren’t available in the market for projects that have dramatically minimized loads. In other words, design decisions can no longer be guided by aesthetics, intuition, and out-of-date rule-of-thumb calculations alone: using data to question and inform every step of the design process is the only way to achieve higher performance and reduced cost. The experts will guide you through these (and more) challenges, and approaches to deal with them, using real world experiences to showcase each scenario and engage audience members to solve their own challenges. Multiple case studies will be used by the experts to cover how data from both predictive analysis as well as post-occupancy evaluations was used to answer the following questions: · How does high-performance compare to code compliance in terms of cost? · What are deep green strategies that every project should evaluate, and how can data and analysis drive a better cost / performance compromise? · How can we lower the CO2 levels to enhance cognitive performance without increasing HVAC system size? · What criteria should be used to develop energy loads and systems selections while improving occupant satisfaction, and how to frame those conversations with owners and consultants? · What are the most cost-effective envelope strategies to reduce HVAC loads while improving occupant comfort? · How to account for improved passive survivability in cost estimation?

Learning Objectives:

Evaluate HVAC design loads to ensure that systems are right sized as an integrated design response to exterior improvements while balancing first costs.

Utilize building science and analysis (daylight/glare, hygrothermal, natural ventilation) to determine most effective design strategies for reducing loads and costs while ensuring comfort.

Establish legitimate occupant criteria to achieve improved air quality levels as recommended in cognitive function studies while not oversizing systems and raising costs.

Dispel the myth that quality design, superior energy performance (NZE), occupant satisfaction and low first costs are incompatible goals thru real data examples.
