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….

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.

Building Performance Modeling Tools for Any Designer

  Originally published on April 4, 2016 by BNP Media through the Architectural Roofing & Waterproofing website. An adapted version of this column was featured in the Summer 2016 print issue of Architectural Roofing & Waterproofing magazine. The building design and construction industry is becoming ever more attuned to high-performance outcomes. Design teams and clients alike are becoming ever more sophisticated with regard to building science and energy conservation measures. Consequently, there is a growing expectation that project teams leverage….

Really Old Buildings are Exempt from the Indiana Energy Code

My firm handles a good amount of preservation and reuse work. Energy-efficiency is always an issue (we make sure of that). However, there is a considerable amount of confusion about how the Indiana energy code applies to historic buildings and renovation projects. Let’s clear the air. Buildings built before January 21, 1978 are exempt from the Indiana Energy Code. There is no substitute for primary source material. Keep these links handy: Indiana Administrative Code (IAC) – Also known as the….

Is Daylight Saving Time Necessary?

Originally published on March 7, 2016 by BNP Media through the Architectural Roofing & Waterproofing Blog. Spring Forward, Fall Back. We know the routine well, but have you ever wondered why the United States uses Daylight Saving Time (DST)? If you ask around, you’ll hear some interesting theories: …so kids don’t have to catch the school bus in the dark?      No. …to save energy?      Not really. …to benefit farmers by giving them an extra hour of daylight?….

Defining Mass Walls through Heat Capacity

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….

The Difference Between Reflectance and Emittance

Originally published on November 18, 2015 by BNP Media through the Architectural Roofing & Waterproofing Blog. What is emittance? Among the three basic forms of heat transfer – conduction, convection, and radiation – the term emittance refers to a material’s ability to release heat through radiation. The term necessarily refers to the heat exchange at surface of a material because heat exchange through a solid would be conductive and heat exchange through a fluid would be convective. Emittance is the….
