DESCRIPTION:
Long before the publication of ASHRAE Standard 189.1 on High-Performance Green Buildings, design teams around the world have been pushing proposals for high-performance architectural design and incorporation of innovative low-carbon systems. Based on first principles, and without the extensive library of performance modeling tools available to design teams today, many successful projects were realized.
In today’s design environment, the energy model is king and ASHRAE, LEED, the New York City Energy Code and NYSERDA set the standards by which designers must assess and report the simulated performance of their designs. The standardization of energy model inputs has opened a fair and consistent dialogue on projected energy performance, but do the available tools and methodologies set by the rule makers actually limit creativity and innovation? The panel will discuss how high-performance designs are realized, how they must be accounted for under current and emerging Sustainability Standards, and how the tools currently available are developing to allow the best ideas to be fully accredited and validated.
ASHRAE’s ongoing efforts in developing Engineering Standards form the backbone of the Sustainability Requirements for new design projects in the New York City area. ASHRAE Standard 189.1 along with 90.1, 55 on Thermal Comfort, and 62 on Ventilation interrelate are all carefully considered throughout the building energy modeling process. Panelists will discuss how these standards may contradict the objectives of realizing a high-performance building.
Panelists will explain SOM’s design process in realizing a high-performance design by outlining the modeling programs that are used and how these tools relate to the Sustainability Requirements of a typical project. The panel will include examples to illustrate how aspects of a high performance design, when assessed through existing standards and tools, provide contradictory results. SOM teams are integrating bespoke advanced tools in their design processes. Current standards and modeling tools are evolving to allow more innovative design opportunities to receive due credit.
Then Philip Haves (LBNL) will delve deeper into the actual mechanics of how energy modeling programs must evolve and innovate in order to harness and assign credit to all architectural and engineering innovations, while still providing a robust energy modeling environment. Philip will also outline the current work that LBNL is doing with EnergyPlus in developing a new Graphical User Interface (GUI), with input from leading A&E firms, including SOM. Philip will discuss how this new GUI, coupled with additional modeling functionality is allowing more and more advanced approaches to building design to be validated and credited in line with the requirements of ASHRAE Standards and LEED.
