Time: 
Oct 4 2011 - 12:00pm - 1:30pm
Meeting Title: 

Envelope Consultants Panel 2 of 2

Location: 

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

Presenters: 

Sean Scott

Dick Burnum, Hoffman Construction

Randy Miller, Portland Public Schools

Isaac Tevit, Ankrom Moisan Architects

Description: 

The second of two BEC presentations for this year focusing on what project specific conditions warrant using an enclosure consultant and what conditions do not warrant inclusion of an enclosure consultant. The first panel discussion focused on the working relationship setup and strategies, and the second panel discussion (October 2011) focuses on working management and roles.

The subject matter of both panel discussions is decided on every project, even if it's by default in replicating past similar project decisions. Thus, hearing from various industry partners on this topic is pertinent.

The panel is balanced on this topic and audience participation via questions and comments is encouraged throughout. Please arrive with questions for the panel. The learning objectives below will form the initial questions for the panel members to start the discussion. The intent of this discussion is not to change viewpoints or debate. Instead, the intent is to have a discussion on a topic that numerous Architecture firms are currently discussing on most projects.

Alternative tools and strategies when enclosure consultants are not engaged will be explored as well as tools to maximize project value if enclosure consultants are engaged.

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.

Building Enclosure Fundamentals from the Perspective of a New York Architect

Location: 

University of Oregon-Portland
White Stag Building
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. Her office in New York City specializes in safe healthy durable energy efficient buildings built for the same price as typical construction. She is Chair of BEC New York.
