In 1999 when the Robert Mueller municipal airport was relocated, the remaining 700 acre brownfield redevelopment was repurposed as a sustainable community. Designed and developed by Catellus a national visionary brownfieldredeveloper, the sustainable redevelopment of Mueller was commenced. strategically located just three miles from the downtown state capitol of Austin, Texas, two miles from Texas A&M university. The Mueller community combines: transit orientated development (TOD), green infrastructure, sustainability, new urbanism principals, smart growth and Leedcertified construction designations, thus reducing automobile dependency, this pedestrian friendly eco neighborhood has became home to over 13,000 residents.
With 20% of Mueller’s 700 acres preserved for open green space, 140 acres of parks, including maintaining native plants and eco landscaping, utilizing reclaimed grey water for irrigation. Developers committing to planting an additional 15,000 trees this infill sustainable eco neighborhood is a connected community with the transportation emphasis shifted to pedestrians and bicycle networks. In turn reducing automobile dependency, thereby reducing the reliance of imported oil into the United States, and limiting rising greenhouse gases into the atmosphere. Which in turn contributes to rising temperatures and global warming. This is a visionary sustainable development especially for the oil producing state of Texas!
A recent 2016 poll from Texas A&M University of Mueller’s residents yielded surprising results. Mueller’s residents spend 90 minutes a week less driving a vehicle. This has resulted in more physical activity and a more healthy active walkable lifestyle!

This sustainable community is constructed to the progressive Austin green building standards which incorporates national LEED green principals/standards. The local Austin energy program is the nations 8th largest community owned electric utility which serves over 420,000 customers. Austin energy is home to the nations first state green building program which started in 1990! Specializing in emerging technologies, Austin energy owns and operates wind farms, a biomass facility, and has a long term goal of supplying up to 35% of its energy from renewable resources In addition this innovative community owned utility operates 113 publicly accessible plug in electric vehicle charging sites through out their designated service area.
In the initial stages of construction of the Mueller community, over 250 residents had solar panels installed on their green certified homes which was included in their greenappraisal and facilitated greenmortgage financing. The is the highest concentration of solar roofs in the country! The Mueller community Energy consumption is monitored by Pecan street the most extension energy monitoring in the US. Community database monitoring has shown 69% of Mueller’s homes electricity for the entire year have been produced by the solar panels!
Bosch a leader in geothermal technology has partnered with Taurus a Boston real estate development company to build a net zero community called Whisper Valley. Whisper Valley will be located just 20 minutes east of Austin, Texas located in the preferred development zone, a master planned 2,000 acre green community of 7,500 homes, multi family homes, apartments, and 2 million square feet of commercial development, all using geothermal technology and air wind and solar technology to obtain net zero real estate certification.
Eco Smart Solution(ESS)
Bosch, along with other manufacturing partners BASF, Rehau, Lighting Science Group Corp. Google fiber, and Aten Solar, are part of Taurus’ Eco Smart Solution (ESS), which develops and implements alternative energy structure programs in large-scale real estate projects. The ESS network includes: construction, finance, technology and communications. The ESS system is designed to deliver value to the homeowner without the initial up front cost, acting as an insurance policy to provide consist annual energy savings to each homeowner.
Rehau will preinstall the geothermal heat loop infrastructure throughout the Whisper Valley community. Due to high air conditioning demand two 250 ton cooling towers will be installed to augment the ground loop rejection. Each home will be connected to the geothermal ground loop with a Bosch heat pump using 350ft. deep geothermal bore holes to deliver constant year round water temperature to provide heating and cooling for each sustainable residence. The geothermal loop will use Bosch water heaters to deliver whole house hot water solution to each net zero home further leveraging the infrastructure. The ESS system will include geothermal, heating/cooling, solar pv and a connection to the community grid for each homeowner. The community wide geothermal loop provides affordable comfortable homes year round that are free of extraneous external HVAC NOISE!
Homeowners individual energy costs will be capped at $175.00 a month for the first three years to cover the initial cost of the geothermal instillation, After the 3 year period homeowners ESS monthly fees will range from $40.00 to $80.00 depending on the size of the home. Each homeowner will a federal, state, or local tax credit up to $10,000. With the average homeowner investment in the ESS system ranging from $20,000 to $30,000. Individual homeowners will have access to an energy monitoring app with data privacy, so each homeowner can track their energy consumption.
LED lighting, solar PV systems, appliances, and maintenance. Each individual home owner will return all excess energy to the electrical grid. The energy costs saved, will be equal to or greater than the ESS monthly fee. Every Whisper Valley home is Ecosmart certified, which includes a HERS rating of 25 or below and is compliance with Austin energy green build 2 star requirements. Whisper Valley homes are 75% more energy efficient than the standard home. This allows homeowners to finance these sustainable improvements by selecting a green appraiser and green mortgage.
A Google Nest learning thermostat will monitor all homes with smart thermostat technology providing remote camera surveillance, smoke and Co2 detection. Google fiber featuring 1GB upload and download speeds, will be preinstalled throughout the community prior to construction. Google fiber is 100 times faster than current internet speeds.
Additional Energy efficient features included in each home are:
Premium Energy star refrigerators, washers, and dishwashers.
Energy Star HVAC ventilation package.
Solar array systems.
Geothermal heat pumps.
Geothermal hot water heaters.
LED advanced lighting systems.
Nest smart thermostat.
The Whisper Valley green community is the largest net zero community in the United States. Combining geothermal infrastructure with solar technology is one of the most cost effective ways to obtain net zero certification. The geothermal loop uses the earth’s constant temperature of 45 to 75 degrees to heat and cool all the homes year round. The entire community is designed and constructed to help the city of Austin municipal building code, obtain its 2050 goal of zero green house gas emissions.(Carbon neutral).
The whisper Valley green community will be clusters of mixed use villages comprised of single family homes, multi family homes, apartments, specialty retail and commercial stores. Surrounded by 700 acres of open space, including a 600 acre Whisper Valley public park, miles of networked biking and hiking trails, community gardens with farm to table delivery, and a planned organic community farm. Two schools and a fire station are also planned.
