Jens Jensen in Indianapolis: The Restoration of Riverdale

The Riverdale Garden: Jens Jensen’s and the Sisters of Oldenburg Influence on Marian University’s Restored Landscape of Art Love of nature and the created order. I first became aware of Riverdale 12 years ago in 2006, when Vice President of Administration, Deb Lawrence, noticed that I had listed Jens Jensen’s small book “Siftings” as one of my favorite books in an Indianapolis Business Journal article.  And so, she sent me a written note to seek my interest in the “befriending”….

Clarifying Energy Simulation Aided Design: A Look at ASHRAE Standard 209

Originally published on September 5, 2018 by BNP Media through the Building Enclosure Blog. ANSI/ASHRAE Standard 209-2018, Energy Simulation Aided Design for Buildings Except Low-Rise Residential Buildings is the product of a half-decade of inertia within the building design and construction community toward leveraging energy modeling a design tool through a project. Standard 209 outlines the minimum requirements for providing energy design assistance using building energy simulation and analysis. To this end, the standard defines a range of minimum criteria from energy modeling requirements,….

How to Make Building Energy Models More Accurate

Originally published on August 13, 2018 by BNP Media through the Building Enclosure Blog.   I’m asked regularly about the discrepancies between modeled and measured building performance. At first blush, one might suspect that the building energy model (BEM) itself contains bad information. That notion could very well be correct! BEM inputs require a certain level of synthesis, interpretation, and assumption. But there are many other reasons why the BEM results may vary significantly from measured performance outcomes on a completed project. In basic terms: Actual weather in….

Beware of Galvanic Action (It’s a Thing)

Originally published on July 10, 2018 by BNP Media through the Building Enclosure Blog. The concept of “galvanic action” is confounding to many design professionals. In simple terms, galvanic action refers to the corrosive effect created when two electrochemically dissimilar metals are in direct contact with each other. Their contact creates a conductive path for electrons and ions to move from one metal to the other. As ions move from one metal to another, corrosion occurs. The remedy is to….

The Psychrometric Chart Explained

Originally published on June 13, 2018 by BNP Media through the Building Enclosure Blog. It is one of the intimidating charts for any building design professional: the psychrometric chart. At first blush, the “psych chart” looks very complicated. There are layers of axes and curved reference lines. However, a closer examination will reveal that – at its essence – the chart is visually conveying the answers to two related questions: How much sensible (dry-bulb) heat is in the air? (See….

Dry-Bulb Temperature, Wet-Bulb Temperature and Enthalpy

Originally published on May 9, 2018 by BNP Media through the Building Enclosure Blog. There is energy in the air all around us. Some of it exists in the form of thermal energy that one can sense – heat in air that impacts one’s perception of thermal comfort. But there is also an energy embodied in the vapor present in the air. While this “hidden” heat is not experienced as warmth, it certainly has a bearing on thermal comfort as….

Interior Design Leader Combats Poverty Housing Crisis by Joining Women Build

BLOOMINGTON, Ind. – In Monroe County, one in five people are living in poverty, the highest percentage in Indiana, according to a Habitat for Humanity of Monroe County statistic. In an effort to support the community she lives in, Lacey Causseaux, Browning Day’s Director of Interior Design, is trading in her laptop for a hard hat and joining the next Women Build. The Habitat for Humanity Women Build promotes the involvement of women in the construction of Habitat houses. The….

Earth Day: A Reminder for Stewardship of Our Resources

As landscape architecture, architecture, planning and interior design professionals, our designs are sensitive to the environment as we orchestrate nature and man-made open spaces to create a symphony of experiences for the people who occupy them. Earth Day, which is on Sunday, April 22, should remind us of the role that we, humans, have for stewarding the Earth’s living resources as part of the created order. We should seek to live in harmony with nature and find more creative ways….

Defining Humidity Ratio and Relative Humidity

Defining Humidity Ratio and Relative Humidity

Originally published on April 4, 2018 by BNP Media through the Building Enclosure Blog. How does a hot-air balloon rise? Fire up the burner and the temperature of the air captured within the balloon increased. The molecules of the air take on the thermal energy and become more excited. The excited molecules create more space between them. As a result, the air expands as its temperature increases. Thus, one pound of air at 80-degrees Fahrenheit (°F) is a larger volume than….
