The Bob Graham Sunshine Skyway Bridge spans 21,877′ or approximately 4.1 miles over Tampa Bay, Florida. The cable-stayed main span was dedicated in 1987 costing 244 million. The steel and concrete structure uses the structural form to create beauty. Designed by engineering firm, Figg and Muller Engineering Group, this structure creates a beautiful experience while driving under the supports. The idea of using structural members to create beauty is common with bridges. The movement created while driving under the cables gave an almost poetic experience.
ASHRAE 90.1: a standard in the US that provides minimum requirements for energy-efficient designs for buildings except for low-rise residential buildings.
Carbon Footprint: a measure of the impact our activities have on the environment in terms of the amount of greenhouse gases we produce.
Carbon Neutral Building: the process of taking into account measuring, reducing, and offsetting carbon energy used by the building.
Cellulose Insulation: a low-thermal-conductivity material use to reduce heat loss and gain from a building.
Ceramic tile: made from clay that has been permanently hardened by heat, often having a decorative glaze.
Commissioning: verification and documentation that a building and the systems used are designed, installed, tested, operated, and maintained to meet the project requirements set by the building owner.
Conduction: the flow of heat through an object by transferring heat from one molecule to another. Think frying pan on a stove or wood stud that touches the inside drywall and the outside wall sheathing.
Convection: refers to the transfer of heat by a moving fluid. Thing warm air rising and cool air sinking in a room. Convection loops circulate near walls. During the heating season, warm air is cooled by exterior walls and falls towards the floor, creating a convection loop. Convective loops can also happen within framing cavities if the insulation doesn’t completely fill the space.
Edible landscaping: the practical integration of food plants within your landscape for the purposes of decorating as well as producing food.
Erosion: the removal of soil and rock by water from one location to another.
A vapor barrier is a barrier that reduces the rate that water vapor can move through a material. There is discussion in the industry if a true vapor barrier is even possible. This has led to the use of the term Vapor Retarder. Vapor retarders limits moisture from passing through a materials and have three classes of permeability. Vapor Retarders per the building code have a permeability of less than 10, less than 1, or less than .1 perm.
There are three categories of vapor retarding materials: Impermeable, Semi-Permeable, and Permeable. Impermeable materials include things such as plastic sheets, vinyl wall coverings, plywood, extruded polystyrene, and oil-based paints. Semi-Permiable materials included expanded polystyrene and latex paints. Most other materials are Permeable including fiberglass insulation, open cell spray foam, drywall, and stucco.
In our mixed-humid climate, we want to avoid using impermeable materials in our wall and roof systems. Allowing walls to dry in both directions is critical to the long-term durability of your structure. To further protect your home, you must have a proper ventilation system that is controlling humidity inside your structure.
Harrisonburg Downtown Renaissance Facade Enhancement Grant
Our first office in Harrisonburg opened in 2009 and the only place we looked for space was downtown. We knew it was the place for us with a vibrant and growing community. We opened an office above Oasis Art Gallery in a very unique, although mostly hidden by ugly metal panels, architectural treasure. Our office was on the second floor in the rounded corner of the building. There was very nice northern lights and plenty of windows. It was a very cool space. We stayed there for 2 years until we outgrew our space.
Our next home, the Bank of America building, moved us to the heart of downtown, court square. This building has amazing architectural details and a landlord that takes care to keep it clean, neat, and in great shape. The space has served us well for almost 5 years. However, we have been looking for our permanent home since moving into this court square destination. With no exterior signage, a lack of accessible access to our office space, and comfort control limitations, we knew it would not be our final home in the burg.
So when rumors started that the Chesapeake Railroad Depot was going to be renovated, we made the call to the building owners. Our goal was to design the renovation and make this our long-term downtown Harrisonburg office location. With an incredible architectural history and most of the original details still in place under many layers of dirt, this is the perfect place to create a sustainable office for our valley branch. We have been working hard to maintain the integrity of the original design while implementing as much cool “green” factor as possible. We are thrilled to be one of the 5 projects selected for a Harrisonburg Downtown Renaissance Facade Enhancement Grant. This will benefit the exterior renovation of our project helping to fund the signage, fencing, and landscape.

Natural Ventilation is the process of supplying and removing air by natural means from building spaces by using windows, doors, solar chimneys, and non-powered ventilators.
Most of us spend about 90% of our time inside of a building. As a result, the indoor air quality is critical to our health, productivity, and comfort. Scientific studies clearly show that buildings with proper fresh air ventilation improves productivity and health for occupants. If designed right, proper ventilation can be used to increase comfort and reduce energy bills.
75. UT Art and Architecture Building #105architecturalinspirations
Designed by Douglas McCarty the Art and Architecture Building at the University of Tennessee in Knoxville, TN was designed to reduce energy consumption and enhance the quality of the interior environment. The building features a four-story open central court. The building highlights the pedestrian circulation experience to encourage interaction and to create community. The open studio spaces brings light deep into the building and connects study space with community space. The professor’s office spaces are extended into the central court space. The exposed concrete and steel offers a pure structural form. The HVAC ducts are painted vibrant colors to bring movement and life to the building. I spent many hours in this building while in graduate school.
The Eiffel Tower, named after engineer Gustave Eiffel, was erected in 1889. This iron lattice tower was built as the entrance to the 1889 World’s Fair. As one of the most recognizable symbols in the world, the structure was criticized initially by leading artists and intellectuals for its design. Gustave Eiffel responded to the critics by saying “my tower will be the tallest edifice ever erected by man. Will it not also be grandiose in its way? And why would something admirable in Egypt become hideous and ridiculous in Paris?” The Eiffel Tower is the tallest structure and most visited in all of France.
With three levels for visitors, the Eiffel Tower stands at 1,063′. There are restaurants on the first and second level. The top level is 906′ above the ground.
ASHRAE 90.1 is a standard in the US that provides minimum requirements for energy-efficient designs for buildings except for low-rise residential buildings. The standard was first created in 1975. It has since been updated on a regular basis in 2004, 2007, 2010, and 2013.
There are two paths for compliance with ASHRAE 90.1, both the prescriptive path and performance path. The prescriptive path requires all building components to meet a minimum set of standards specified in ASHRAE 90.1. The Prescriptive path includes requirements for building envelope, HVAC, domestic hot water, power, lighting, and other equipment. The performance path shows compliance using a building modeling program to illustrate that the design uses less energy than the baseline building built to ASHRAE 90.1 specifications.
A light shelf is a horizontal overhanging element located above the eye-level and typically having a highly reflective upper surface. Sunlight hits the top of the light shelf and bounces inside of the structure hitting the ceiling. This brings light deeper into the structure that reduces energy usage for lighting and glare.
