from the course description Program Information

The use of energy modeling has increased significantly due to the growing popularity of the LEED (Leadership in Energy and Environmental Design) program. The LEED program, developed by the US Green Building Council (www.usgbc.org), encourages sustainable and energy efficient design, which is determined by comparing an energy model of the building's design with a model of the same building built to ASHRAE 90.1 minimal efficiency requirements. Although performing a model is required for LEED buildings, it is a strategy that should be used in all building designs, to ensure the best decisions are being made regarding energy efficiency.

Incorporating energy efficiency into building design may be the strategy that provides the best return on investment in the entire process. Efficiency can have a much greater impact during the design process for new construction than in existing buildings, since annual savings are compared to incremental increases in cost, rather than whole replacement costs. Many smart design strategies don't result in any additional up front costs. For example, if you start with a standard building design, and decide to make an investment in high-efficiency windows, you may spend a small incremental additional cost up front. However energy efficient windows, in addition to reducing energy consumption, also reduce the peak cooling and heating loads, therefore the cooling and heating system could potentially be downsized. In many cases, the incremental costs for high performance windows are more than offset by lower initial central plant costs, resulting in a net reduced first cost.

Energy Simulation modeling should be integrated in the very early stages of schematic design. Using default assumptions for mechanical systems and building envelope characteristics, you can run a simulation with different orientations of the building to determine the one with the lowest predicted energy costs. Once this has been determined, similar types of analyses can be run comparing different wall types, window configurations, roof types, and even design characteristics such as window overhangs and skylights. During Design Development, the energy model can be used to quantify savings from strategies like daylighting control, window characteristics, shading devices, and air supply strategies such as demand controlled ventilation. Since all buildings have a limited budget, the ability to quantify energy savings from design strategies, compared to the incremental costs, can show where the biggest "bang for the buck" can be found.

70 NW Couch, Room 142/144

Presenters: 

Chris Benedict

Description: 

Chris Benedict, using examples of her own work, will talk about the evolution of the system approach to building design and the profound position that the building enclosure holds as a part of that system. She will lay out her perspective on building enclosure fundamentals, including the management of air, water, vapor, light and heat and discuss how mechanical systems and materials can be refined, reduced or eliminated, while building performance is enhanced, when the relationships within the system are clearly understood. Most of her discussion will be about innovations in the many apartment buildings she has designed and seen through construction, both retrofits and new construction. Some unusual aspects of her practice include: Inventing new construction techniques and building systems Changing code Stepping out of the traditional role of “Architect” and into Engineering and “means and methods” She will talk about the importance of thorough construction documents, active construction monitoring and crunching energy bills. Chris will end her talk with a presentation of her newest building, a 24 unit apartment building about to start construction that is planned to meet the strict German Passive House Standard.

Chris Benedict is an Architect, a Graduate of Cooper Union for the Advancement of Science and Art, and a professor of Architecture at Pratt Institute.

Keeping up with Glass Technology

Location: 

University of Oregon-Portland
White Stag Building
70 NW Couch, Room 142/144

Presenters: 

Stanley Yee

Description: 

The use of glass and fenestration as part of the building enclosure material/system has become a significant consideration and component in today’s building design. Glass in a building enclosure is used as the medium that breaks down the visual/psychological barrier between the interior and exterior of a building. Glass introduces natural daylight into a space and provides views of the outside while it simultaneously keeps the forces of nature to the exterior.

However, glass and fenestration technology has also rapidly evolved in recent years - predominantly to address energy conservation concerns. These advancements and product offerings range in aesthetics, performance and application. This meeting will explore and discuss current glass and glazing system technology and how the wide range of product availability can be more optimally incorporated into our projects with desired aesthetic and performance results.

Stanley Yee is a partner and building enclosure consultant for The Facade Group, a building enclosure consultancy based in Portland, OR. The Facade Group provides building enclosure design/construction expertise and support to building owners/developers and the architectural/engineering/contracting community.

Building Envelopes and Energy Balances

Location: 

University of Oregon-Portland
White Stag Building
70 NW Couch, Room 142/144

Presenters: 

John Breshears

Description: 

The University of California San Diego is has commissioned the design of a new 177,000 square foot Health Science Research Laboratory on its main campus in La Jolla, CA. Based the on the experience and the mission of the institution, one initial goal for the project was to create as nearly as possible a daylight-autonomous laboratory building. The goal was subsequently refined to include the design and optimization of a façade system that yielded the maximum daylight benefit with minimal cooling penalty. John Breshears will present the design, simulation, and analysis findings relative to building envelope as well as a site-specific dynamic solar shading and glare control system. John will also give a brief description of the concept for an enthalpy recovery ventilated façade system. This project was recently awarded a research grant under the Department of Energy’s ARPA-E program for development by a team including Architectural Applications LLC, Membrane Technology Research Inc., and Lawrence Berkeley National Laboratory.
