[Audio] H-E-B at Mueller, an 83,587 square foot retail store and fresh food market, includes a pharmacy, café, and community meeting space. It is located in the Mueller neighborhood, a mixed-use urban village in Austin, Texas located just three miles from downtown and two miles from the University of Texas, with excellent access to public transportation, open space, and bike routes. The project site is in the Mueller market district and backs to the south onto a residential portion of the development. Input from the 16 surrounding neighborhoods and the City of Austin informed the project design, which showcases many sustainable design innovations..

[Audio] VERNACULAR ARCHITECTURE OF THE REGION. VERNACULAR ARCHITECTURE OF THE REGION.

[Audio] Austin's vernacular architecture has been shaped by a variety of cultural influences over time. The earliest structures were built by Native Americans using materials such as adobe and grasses..

[Audio] Later, Spanish colonizers introduced elements such as stucco and tile roofs. VERNACULAR ARCHITECTURE OF THE REGION.

[Audio] In the mid-19th century, German immigrants brought their own style of architecture to the area, characterized by half-timbered houses and decorative woodwork. Stonework normally appears in the ground floor of the house, and gives way to half-timbering in upper levels. VERNACULAR ARCHITECTURE OF THE REGION.

[Audio] VERNACULAR ARCHITECTURE OF THE REGION African American communities also contributed to Austin's architectural heritage, with examples such as churches featuring steeples and ornate detailing..

[Audio] VERNACULAR ARCHITECTURE OF THE REGION They also introduce the new house typology called shotgun house. A shotgun house is a narrow rectangular domestic residence, usually no more than about 12 feet (3.5 m) wide, with rooms arranged one behind the other and doors at each end of the house..

[Audio] H-E-B at Mueller is located at the former Robert Mueller Municipal Airport site, which has been redeveloped into a sustainable urban village.

[Audio] CLIMATE CLASSIFICATION Köppen- Gieger Classification - Cfa C – Warm Temperate F – Fully Humid A – Hot Summer Average Temperature: 68°F.

[Audio] Grocery stores serve as important neighborhood amenities, so H-E-B has established public space throughout the Mueller store for community interaction A large canopy roof pays homage to the previous airplane hangars on the site. Functionally it acts as a shading device for the store and its many users..

[Audio] The H-E-B Market's design responds to Austin's highly variable humidity with a vestibule that transports and expels heat out the top.

Rain gardens capture runoff from the parking lot, acting as a natural filtration system and slowing the flow of water into the regional water quality system.

[Audio] Average rainfall A skylight study aimed to optimize energy performance, daylight autonomy, and uniformity. North-facing rooftop light monitors with clerestories offer glare-free indirect daylight. The store's slightly lower ceiling is balanced by the clerestory roof, preventing a confining atmosphere. The reduced wall height offsets monitor costs..

[Audio] The section of the building designed to block the intense summer sun while welcoming the winter sun plays a pivotal role in energy efficiency. This carefully crafted skylight design ensures that, in nearly 95% of daylight hours, artificial lighting is unnecessary, resulting in substantial energy savings. By harnessing the natural illumination provided by the winter sun and minimizing the harsh glare and heat from the summer sun, this architectural feature not only enhances the building's sustainability but also fosters a more comfortable and eco-friendly environment for its occupants..

[Audio] In this scenario, the nighttime lighting has been designed with an automated system LED lights that effectively reduces glare and minimizes eye strain. The establishment has opted for LED lighting across the entire area (parking lot, building exterior and interior, walk-in coolers and freezers, and refrigerated display cases), and these lights are controlled automatically based on the establishment's operational hours and the natural light conditions. This automated approach guarantees that artificial lighting is employed only when needed, thereby promoting energy conservation. It results in a welcoming and well-illuminated environment, a strategy that can be adapted to a variety of settings and industries, not confined solely to retail..

[Audio] H-E-B aimed to create an enjoyable shopping environment at the Mueller store, prioritizing thermal comfort to eliminate any discomfort caused by cold refrigerated sections. To achieve this goal, they installed destratification fans to distribute warmer air effectively and ensure even heating in colder areas. Passive chilled beams were strategically placed in key spaces such as the community room, employee break room, and administrative offices. Additionally, they adopted seasonal temperature and humidity settings that link indoor conditions to the outdoors. This not only reduces energy consumption but also enhances user satisfaction by keeping shoppers and employees comfortable..

[Audio] Philosophic elements are uncommon in grocery stores, but H-E-B at Mueller uses views, daylight, and a sculptural glass water wall (that still activates the space when water cannot be used due to seasonal restrictions) to enhance customer experience by reducing stress. The wood roof structure, including wood decking, acts as both an exposed ceiling and structural roof decking. This provides acoustic attenuation and a visually warmer, more natural appearance to the customer areas of the store interior. Building materials contain 54% Texas-sourced content by value. Nontoxic finishes (eliminating vinyl floors and offgassing paints for instance) improve indoor air quality..

[Audio] Parking lot runoff is filtered and treated through landscape and drainage strategies. On-site rain gardens manage 100% of storm water. H-E-B at Mueller does not use potable water for any end uses not requiring it, but instead utilizes the City of Austin's reclaimed water system for these needs. Reclaimed water is combined with air conditioning condensate for cooling tower make-up water. 82% of the store's total water consumption is provided by cityprovided reclaimed water, which is 1/4 the cost of potable water. By reducing water demands where practical and maximizing use of reclaimed water, H-E-B at Mueller was able to substantially lower its total water bill. Percent reduction of regulated potable water: 60% Percent of rainwater from maximum anticipated 24 hour, 2-year storm event that can be managed on site: 100% Water Performance.

[Audio] Electricity is the primary expense in store, and to achieve cost savings, it's crucial to decrease our electricity consumption. Over 50% of our energy usage is attributed to refrigerators and coolers. Therefore, effective control and management of these units are vital for cost reduction. An innovative propane refrigeration system with zero ozone depletion potential and low global warming potential allows for 95% less refrigerant than conventional systems. A 169 kW roof-mounted solar photovoltaic system generates enough electricity to power all the store's lighting. Design phase energy models estimated that the store would exceed the 2013 2030 Challenge target of 60% reduction ENERGY PERFORMANCE.

[Audio] In conclusion, this sustainable grocery store's commitment to reducing operational costs has enabled them to offer competitive prices to their customers. Their dedication to achieving low energy consumption not only contributes to cost savings but also creates a comfortable shopping environment while aligning with eco-friendly practices. This store exemplifies the positive impact that sustainability efforts can have, both on the bottom line and on the wellbeing of the community and the environment. Certainly, here are some remarkable features of this sustainable grocery store: The rain water garden collects runoff from the parking lot, operating as a natural filtering system and slows the flow of water into the regional system for maintaining the quality of the water in the mueller neighborhood. Innovative propane refrigeration technology uses 95% less refrigerant than traditional systems and has zero ozone depletion potential and very low global warming potential. solar panels, which cover 11,000 square feet of roof space, provide more than 2000 kilowatt hours of electricity yearly, enough to power around 16 dwellings. Reclaimed water is used for landscape irrigation and restroom flush fixtures, and is combined with air conditioning condensate for cooling tower make-up water Building materials contain 26% recycled content and 54% Texas sourced content by value. More than 84% of construction waste was diverted from the landfill.
