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….

Applets for Energy and Environmental Design

Originally published on July 10, 2017 by BNP Media through the Building Enclosure Blog. Newsflash: There are a lot of great (and free) online resources for design professionals. When I am having exchanges about energy and environmental design analysis with colleagues and students, it seems like I am constantly referring them to any number of small, accessible online utility programs for performing simple – yet highly sophisticated – functions. Some would refer to these small programs as applets. Below, I have….

Embrace the Data

Originally published on March 7, 2017 by BNP Media through the Building Enclosure Blog. In work as in my personal life, I am often thought of as “a data guy.” Whether it is a personal activity tracker, a vehicle dashboard that provides a breakdown of fuel efficiency, a home energy monitor, or my daily perusal of MLB box scores, I tend to be immersed in numbers constantly. I often like to lean on numbers because they can provide some measure….

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….

BECx is Coming to a Project Near You

Originally published on January 11, 2017 by BNP Media through the Building Enclosure Blog. . In recent years, a growing demand for high-performance building envelope solutions has been evidenced by the increased attention paid to this topic throughout the building design and construction industry. Building Envelope Council (BEC) initiative Seeing this emerging priority, in 2004 the National Institute of Building Sciences (NIBS) Building Enclosure Technology and Environmental Council (BETEC) and the American Institute of Architects (AIA) signed an agreement to….

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….

The Difference Between Permeance and Permeability

Originally published on April 18, 2016 by BNP Media through the Architectural Roofing & Waterproofing Blog. All information presented in imperial (I-P) units. Water vapor transmission is a rather confusing issue. The difference in vapor pressure between two sides of a building envelope assembly is the driving force behind vapor transmission. (Although by comparison, gaps in the envelope account for vastly greater amounts moisture migration due to vapor-laden air infiltration.) Vapor = Latent Heat; Air Temperature = Sensible Heat The….
