Walmarts typical American condition allocates separate representative and performative functions to each face. Friendliness toward a host culture is generated through the materiality of the vertical facades or in the articulation of peaks and corrugations through the parapet wall. Meanwhile, the buildings relationship to the exterior environment, both physical and meteorological, is framed primaily through the conguration of the parking lot, plantings, and drainage areas. This duality produces a divorce between investments in environmental friendliness and those in cultural friendlinss. By embedding both of these functions in the cornice and the sot, a more integrated solution can be achieved.
I. RELATIVE VALUE
By examining surface area and volumes in proportionally related exemplars of each type, we can see that the roof is the dominant face of the FH (Flat Horizontal) type, as it comprises at least 41% of the surface area of any Walmart store. Dominant faces of other typologies are highlted in red and grey, their values having been highlighted as well.
The drainage strategies outlined to the left produce solutions embedded with latent biases with regard to a stores site-inclusiveness, which one may desire to either mitigate or amplify, depending upon local-cultural micro-climates or more general societal attitudes. The techniques employed toward these ends may also be modied to respond to diering rainfall amounts in a given location and also may be combined with variations upon the techniques of curvature and faceting shown below in order to form more explicit relationships with the stores surroundings.
One of the major upshots of the large spaces required by big-box retailers like Walmart is the sense that the interior becomes a sort of environment-unto-itself with no apparent relationship to environ-mental conditions or exterior space. For retail purposes, this disorientation is sometimes preferable, while at other times this lack of experiential continuity between itnerior and exterior is detrimen-tal. As the sot is the only continuously available (visually) plane of reference from the interior of the store, the sizing, orientation, and distribution of the skylights takes on a great deal of importance with regard to orientation as well as to interior illuminance. A typical bay conguration for a revised temperate American Walmart is shown below.
By always using PV panels as skylight shading devices and orienting the entire assembly to take advantage of dominant sun direction, the interior is localized with regard its global coordinates while environmental gains are also achieved.

Flat Horizontal: WalmartWalmart has utterly dominated the American retail sales market since its inception in 1962. However, its domestic dominance has not always translated to success in international arenas. While Walmart maintains a presence in over a dozen countries, the majority of its statistially signicant international sales have been in neghboring Mexico and Canada. Walmart is slowly on its way to approaching what apperas to be complete market saturation in the U.S., and, if the future holds true to present form, it will need to confront its inability to gain market share overseas in order to retain its current status at the top of the retail market.
Many of Walmarts problems may be attributed to an inexibility of its stores with regard to previaling local conditions. For all of ruthelss eciencies in almost every area, however, Walmart has yet to develop a systematic way of responding to local cultural and environmental conditions in a way that makes these variations readily apparent and thus eective inectors of experience or branding tools. It is the production of a guide to such a system of expressive eciency that is PEGs goal.
In researching Walmart and its links to the broader Flat Horizontal type, we have focused our attentions on the roof, as it comprises the greatest part of Walmarts surface area and engagement with the environment while also acting as the dominant face of the bui
