Leveraging Life Cycle Assessment in the Design Process

Originally published on October 11, 2017 by BNP Media through the Building Enclosure Blog. While environmentally responsible design and sustainable building practices have become increasingly prevalent in the design and construction industry, decision-making for building products and materials have historically focused on single attributes such as regional manufacturing, recycled content, or consisting of renewable materials or certified wood. It used to frustrate me that there was not an efficient way to make holistic decisions about building products and materials that….

Energy Use Intensity (EUI) in Simple Terms

Originally published on August 17, 2017 by BNP Media through the Building Enclosure Blog.   Energy use intensity – or EUI. It has been called “the miles per gallon rating of the building industry,” but many design and construction professionals are not entirely sure how EUI is defined and what its utility is with regard to project. Below is a primer to help get anyone started.   Energy Use Intensity (EUI) Energy Use Intensity (EUI) can be defined as the….

Stages of Design and Types of Energy Models

Originally published on February 13, 2017 by BNP Media through the Building Enclosure Blog. . The publication An Architect’s Guide to Integrating Energy Modeling in the Design Process is a comprehensive (and free) 86-page document from the American Institute of Architects (AIA) that defines the fundamentals of energy modeling, outlines the current state of various performance and analysis tools, and foretells the direction of an architectural industry increasingly focused on performance-based design. Among other components of the document, the guide….

Here is Your Elevator Pitch Against “LEED Equivalent” Projects

Originally published on December 6, 2016 by BNP Media through the Building Enclosure Blog. Have you ever been asked to design or construct a project “to LEED’s standard” without actually submitting for certification? This can initially sound like an attractive idea to a client. After all, as long as the owner knows the project is aligned with LEED, why pay the funds to get a plaque on the wall?   Lack of Accountability with LEED Equivalent The problem is, an….

How to Find the Target EUI for the 2030 Challenge

Originally published on August 15, 2016 by BNP Media through the Architectural Roofing & Waterproofing Blog. The 2030 Challenge prompts building projects to meet a fossil fuel, GHG-emitting, energy consumption performance standard of 70% below the regional (or country) average/median for that building type. The metric for the 2030 Challenge is site Energy Use Intensity (EUI), not source EUI. But how can a design team quickly determine the appropriate EUI target for a project? Here are three easy ways.

Five Ecotect Functions that Need to Be Migrated to Revit

Originally published on May 18, 2016 by BNP Media through the Architectural Roofing & Waterproofing Blog. Eight years ago, Autodesk made a bold and decisive move toward prioritizing sustainable design tools when it acquired the assets of Square One Research, including their design performance modeling software Ecotect. To that point in time, Dr. Andrew Marsh had incrementally built the Ecotect platform into a light, versatile energy analysis tool. Its playful graphic outputs and high degree of interoperability made it a….

Defining Mass Walls through Heat Capacity

Originally published on February 12, 2015 by BNP Media through the Architectural Roofing & Waterproofing Blog. There are significant differences in the prescriptive requirements of mass walls versus other above-grade walls. Using ASHRAE 90.1-2007 as example, above-grade walls for a steel-framed nonresidential building in Climate Zone 5 will need a minimum of R-13 insulation AND a continuous insulation layer of at least R-7.5. However, the building’s mass wall assemblies would only be required to exhibit a continuous layer of R-11.4….

When the ‘Prevailing’ Wind Direction is Anything But

Originally published on June 1, 2015 by BNP Media through the Walls & Ceilings Blog. The wind rose is a conventional diagram for characterizing both the direction and frequency of wind around a project site. This graphic is commonly included in a climate data analysis. Some software platforms such as Climate Consultant, one of several free energy analysis tools developed and released through the University of California, Los Angeles (UCLA) Department of Architecture & Urban Design, can generate wind roses….
