Written and Researched by Kierstin Melson History Information The Fort Lewis College students, faculty and administration collaborated in 1998 towards the creation of a sustainable building for recreation, outdoor pursuits and intramural programs for students. Funding for the building comes directly from student fees. Because of this factor the students had to approve the additional fees that would increase the construction of the facility. The motivating force to place emphasis on environmental and ecological features came directly from the student body. Students were given an opportunity to voice their concerns and directly influence the design process. There was a survey that examined the additional fees and explained that the building would be designed and built in the most ecologically sustainable manner possible, within construction funding limits, and in accordance with the Federal and State Statutes. Portions of the fees were split into temporary costs (expiring when the design and construction costs are paid) and permanent costs (operational costs for the upkeep of the building). The survey showed that 71% of the 951 students were more inclined to approve additional fees if sustainable concepts were incorporated. Therefore the top priority of the students, above all other functions of the building, was sustainability. The student body approved the additional costs for the building of the Student Life Center. With the students backing the building, a Student Life Center Steering Committee was formed which included students, faculty, staff and administration to evaluate the cost benefit of energy sources. In the Final Submittal of Energy Efficiency/Sustainable Design for Fort Lewis College, prepared by Gordon, Gumeson and associates, Inc., goals were stated upfront in order to minimize consumption of limited resources and minimize pollution by utilizing energy as a resource, and not a pollutant. The report estimated anticipated energy use of the building, analyzed energy efficiency measurements and calculated approximate costs and payback periods associated with each sustainable feature of the building. Two lists were constructed in order to evaluate and measure cost analysis between energy requirements and options of energy reduction. The “A-List” was a list of “readily available” items, and the “B-List” was “desirable, but needed additional study. This work was a collaborative effort of the design team (Gordon, Gumeson and Associates, Design Balance, Architectural Energy Corporation and Sink-Combs-Dethlefs) with input from Fort Lewis College Facilities Personnel and Student Representatives. Some of the main components in the buildings ability of minimizing energy consumption were to: favor renewable energy resources; minimize pollution of air, water, and soil. Renewable energy sources that were studied towards using were: Solar: Wind: Others:

Other Information:
The building is mainly made up of Concrete Masonry Units (CMU’s) they have a minimum of 10% and maximum of 20% fly ash content. This is a bi-product of combustion, which means that not much of the material is taken out of the ground but is recycled with fly ash, a substance that is mixed into the masonry and grout. There is a very involved process of making cement, and what is special about the CMU’s that were used in the Student Life Center is that this material does not require more finish, the CMU’s are used on both inside and outside the building, the color matches the rest of the campus buildings, and the company that supplied them makes them in batches, so that none is wasted. Sidewalks, foundation, floor slabs, grout and mortar were used in the building. Leaving the walls natural inside of the building allows for a very resource efficient environment. Instead of placing drywall over the masonry (in designated places in the building), the architects simply left it as a finished material. This creates less use of unneeded products because it eliminates the need for repainting and adding toxic chemicals to the building. As a result, the material is very easy to maintain. A local company produced the masonry, which aids in efficiency because of the reduction of transportation and pollution costs. The sandstone comes from a local quarry in Balding, Utah.

This aluminum is thermally broken, which means that when a window is installed, there are two frames, and this acts as an insulator. The frame does not leak because there is also rubber in-between the aluminum. Manufacturer
The sloped steel roof is highly durable and the structure is insulated in order to reduce energy and maintenance costs. The original 1999 steering committee goal for the building was to provide a solar energy feature so the building could produce it’s own energy. Unfortunately the funds were limited and solar panels were unable to be provided. However, the way in which the roof has been installed creates the option for solar panels in the future, and it will be up the to students to decide whether the cost is worth the amount of energy that we can save. As gas and electric costs rise, the solar panels will become more feasible for the school to pay. When you walk into the Student Life Center there is an open feel in
the building. The interior of the roof adds to this feeling of freeness.
In order to create this feeling of luminous space, the roof has been left
exposed. By not completing the inside ceiling structure there are
less costs for other unnecessary material, thus highly resource efficient.
Like the masonry, the roof has been left alone to show the guts of the
building, as a result there is a more natural sense of openness. One of
the more important sustainable parts of the building is the control of
natural light. The unfinished deck is painted white and helps diffuse
natural light into the space below.

sunlight, thus reducing on electrical lighting. Angling the building
in a way that it can use as much light as possible is a form of day lighting
design. When the sun is going down, the west side of the building
has many windows to filter light through; this concept is also a form of
energy efficiency as well as passive solar design. East and
west day lighting is more difficult to control, then south and north. The
north side has many smaller windows that are mainly used in bringing natural
light into the gymnasium. The long axis of the building allows maximum
use from the south and north, which allows a reduction of energy use of
electrical lighting.
Energy efficiency is a very important feature that the Student Life Center has to offer. The ways that the sun is used in the day lighting design of the building contributes highly to lowering the use of electricity and utility costs. Overall, the more that we try to utilize our renewable natural resources, the less damage we will cause the environment. Design Team Involved:
glass, one of which is coated with a low emissivity (low-e)
compound (glaze which admits wavelengths of visible light but not most
Infa-red). This glaze has high performance results and is used in
areas of the building that receive the most light. As a result, the glazing
helps keep the building warm in winter and cool in the summer. The
type of low-e coating varies on the North, East, West and South facades
of the building to “tune” the performance to the needs of the building
(high performance and low performance glaze). For example, on the
west side the glazing should reject excess heat and light on a summer afternoon,
whereas the north side glazing should have excellent insulation properties
and admit as much light as possible. However, not all of the widows
are low-e, the cost of these kind of windows is very high, therefore different
places were not as necessary to coat. The skylight consists of a
different material all together, so that the low-E glazing is not necessary
for this source of natural light.

D. Day lighting and Electric Lighting
1. Hallway
The lights are not hovering and creating circles of spotlights
on the floor. The Student Life Center gymnasium uses indirect lighting
to create an even distribution of light. There are three levels of
illumination. Higher and lower light control are used in the gym for the
upper track and the lower courts. Natural light from the windows above
the track create indirect light. The light fixtures are aimed towards the
ceiling and bounce off of the unfinished white painted ceiling in order
to create an even luminous distribution of light. These fixtures
require large amounts of electricity and are not as resource efficient
as the students had hoped for. However, these lights can be switched off,
half on, or fully on depending on the activity in the gym. They are fairly
efficient, and the indirect light creates a perceived brighter space. There
are 18 fixtures in the new gym and compared to our old gym, these lights
produce two times the amount of light.3. Main Lobby A translucent panel skylight in the main desk area provides natural
light for the cardio room and the information area below. This skylight
does not have the high tech features of the Infra-red windows that keep
the heat of the sun out, but the glass is not clear and blocks some heat
gain. These features are explained in better detail in section II.
C. Like every skylight, it simply reduces the costs of electrical
light during the day, and has a light transmission of 56%.

1. Wood Most wood that is harvested in and out of the United States is generally from unsustainably logged forests. One of the goals the students were looking for in the lumber products was a source that contributed to the forests and utilized sustainable practices. These practices include harvesting
that promotes bio-diversity, replaces and replants what is taken out and
protects the eco-system. These are some of the different ways that
timber companies can reduce the destruction of our natural habitat. Instead
of burning and slashing to extract the wood, these companies harvest selected
trees and/or replant trees to reduce the impact of our eco-system. Wood
in the Student Life Center is certified and harvested from managed forests
in compliance with the Smart Wood program of the Rainforest Alliance (international
non-profit conservation organization) or certified with the Forest Stewardship
Council and are products produced from sustainable managed forests.
a. Gym Floor The gym floor is maple flooring, and is in compliance with the Smart Wood program. The wood is #3 flooring, which is a multi-purpose surface. #3 flooring is better environmentally because it uses different grades of wood, which enables a good serviceable floor. The 19 thousand square foot #3 flooring creates diversity in color, grain variation and provides for a much more natural overall look, and is often selected for its character. The original design called for a water-based polyurethane/(less toxic) sealer for the wood flooring. However, it was decided that the oil based sealer, which is more toxic and contains more VOC’s, would be better because of the less frequent refinishing that it will take to keep the floor in good shape. Water-based sealers require far more re-covering than oil-based sealers, hence the decision is based on the line of what is more efficient; re-covering the floors often, or not as frequent, but with a larger quantity of toxic material.
b. Racquet Ball and Aerobic Courts The wood that was used for these rooms is called #1 flooring, in which the facing floor has less defects and color differential. The purpose of this wood is for competition. (In a racquetball court everything must be of the same color to avoid visual distractions of light)

The carpet has recycled content of 50% minimum, and can be recycled at the end of its useful life in an environmentally responsible manner. This program reuses 100% of the current carpet to create a new-value added product. The adhesive system is made from 100% recycled material and was created at the time it was manufactured. The adhesive system is also a water-based adhesive with zero VOC’s, which protects indoor air quality. Over the years Europe has promoted excellent recycling policies, one of those includes companies that you rent your carpet from and they in turn recycle it for you. Unfortunately this concept has not caught on in America. Most carpets are left to fill landfills after their short life of use. However, there are a small number of companies that are starting to practice more sustainable ways of reusing fiber material. The manufacturer that was used has a 1-800 number that will be called when the lifetime is up, and they will be able to recycle it back into carpet on other fiber-based products. Solution die is used in the carpet and it’s base. Solution dye is more durable and requires less prone to bleaching or discoloration. The Base Carpet: 60% solution Die, 40% Yarn Dye
The majority of larger buildings use a rubber wall base to protect the wall from the wear and tear of vacuums and other maintenance cleaners. The Student Life Center chose to use carpet whenever possible, instead. Carpet as a wall base is more durable and easier to maintain than a vinyl or rubber wall base. Carpet can also be recycled, whereas there are no current programs to recycle rubber base or vinyl base. Company: Collins and Ailkman Floor Coverings
*Unfortunately the yarn is 100% Dupont Nylon. This means that
there is no actual recycled material in the yarn.
The main hallway’s/gallery’s floor is extremely resource efficient.
Most people don’t consider concrete to be a natural product, however it
is, and it is very simple to make. The floor is made of concrete that has
been stained instead of adding other final finish material such as tile
or carpet. The concrete is stained with a water-based pigment that
is less toxic than other coatings. By using water-based pigment there
is a lower count of VOC’s, which helps protect indoor air quality.
By leaving the concrete as it is, there is less maintenance or repair.
This is a very durable way to create a hallway that will have high traffic
and lots of wear and tear. It just seams like the natural thing to
do. The finish and pre-stain is a water based latex blend.
This way of sealing the concrete creates a breathable membrane within the
substructure. The topcoat is a polyurethane blend that creates highly
durable coating for vehicle and pedestrian traffic.

Other Information: There is 240 grams a liter of VOC’s which is
fairly low.

b. Track Floor
Foot traffic is the main purpose of the track; therefore the need for durability is essential. Rubber is one of the easiest materials to recycle and the durability is the same as new product rubber. The track material has a high abrasive resistive coat for long life. This also includes features such as noise resistance, strength of material, bounce (cushy for the feet), and fire resistance. This surface is environmentally safe by design because the material is prefabricated rubber and is created with all recycled rubber granules. The granule material consists of plungers, water bottles and tires. The red color is highly recycled material and the black and tan colors have a lower content. There are no solvents, mineral fillers or pigments. The backing for this product is also up to 90% recycled content. The company does not use PCB’s, fluorocarbons, formaldehyde, lead, mercury or metals in the material. Rubbers and metals are the easiest material to recycle and are just
as durable as virgin rubber and metal. Tennis courts and other outside
recreation facilities, which use recycled rubber, are just as long lasting
as un-recycled materials.

1. Steel/Metal
The recycled content in different steel ranges from 68% to 95%.
The 95% applies to the small products such as steel studs. The larger
structural members are 68% recycled because there are more structural
requirements,
and they are larger making the material more durable.
The steel/metal materials that are used because it is a very durable
material with a high recycled content and are completely recyclable.
One of the architectural goals of the building was to have a feel of health
and awareness. The way that the metal has been placed in the gym’s
ceiling and the main stair area is structurally important as well as spatially
pleasing. The way that the metal and steel were placed is also resource
efficient because it has not been covered up with unnecessary materials.
This allows for the light to show through the unfinished features and visually
shows how sturdy the building is, while bringing a feeling of openness. Companies: Open-web steel joints

The initial goal of the students was to find a tile containing at least
15% recycled content. Fortunately, the company that was found provides
a product that is 55% recycled glass and other select ceramic materials.
This is an environmentally friendly product that is located in the boys
and girls’ locker rooms and other restrooms in the building. The
product is meant to be floor tile, but it looks jazzy on the walls.

Company: Bio-composite Producer
Millwork is fabricated architectural woodwork. The boards that are
used on the top front of the cabinetwork are created out of an agriboard
that comes from un-used agricultural waste (post industrial). The
boards are a blend of different bio-based resins. This material is
100% recycled from agricultural waste that would otherwise be burned.
The tan colored product is highly resource efficient with no resin or formaldehydes.
The company calls the brand RANGER MDF (Medium Density Fiberboard).
The clear water based seal helps with low VOC requirements, while the board’s natural feel lets the material just be the material. This material takes little to no maintenance work and has long lifetime expectancy. Companies: The Panel Boards
