Eco-Friendly Designs


hen Dan Brunn, AIA, Principal of Dan Brunn Architecture, set out to design Bridge House, his concept was straightforward yet ambitious: create a home that connects to nature in the most seamless way possible, using eco-friendly solutions to ultimately achieve a net-zero home.

The one-of-a-kind home is aptly named Bridge House not only for the fact that it stretches across a stream bed in urban Los Angeles but for the way that it bridges modern living with the natural environment. The design exemplifies Brunn’s signature minimalist aesthetic while integrating innovative systems and forward-thinking processes.

With water as an essential element to the overall design of the home, Brunn was particularly interested to work with a water partner that could help bring his vision to life, and he turned to Pentair, a leading provider of water treatment and sustainable solutions. With a broad range of technologies to treat, filter and manage water as well as energy-efficient pool and spa solutions, Pentair delivered a whole home water solution to help achieve Brunn’s sustainability objectives.

“Water has a purposeful function as well as an aesthetic that appeals to all of our senses—sight, sound, taste, flavor and touch,” says Brunn. “Through the collaboration with Pentair, we were looking to create a heightened experience in the way one interacts with water throughout Bridge House, while also ensuring that we are managing the water in a sustainable way.”

As part of Brunn’s vision to connect the home with its natural surroundings, indoor and outdoor living spaces blend effortlessly throughout. An infinity pool and spa provides a relaxing space for friends and family. Pentair focused on delivering technologies that would provide an easy and enjoyable experience while contributing to Brunn’s goal for a net-zero home.

“For me the pool is a spot for levity, both in mind and body.  I yearn for the moments I can get some time, to myself as a place of reflection and exercise,” says Brunn. 

According to the U.S. Department of Energy, a pool pump can be a home’s second-largest energy consumer, behind the heating and cooling system.* Pentair introduced variable speed pool technology to the industry in 2005, which allows the pool owner to adjust the flow rate of the water through the system at varying speeds. This results in the ability to operate the pump for longer periods at lower speeds, delivering up to 90% energy savings.** The Pentair IntelliFloXF variable speed and flow pump was selected for its ability to deliver performance and efficiency for the large and feature-rich pool with high flow demand.

To further improve the pool’s energy efficiency, Brunn selected the Pentair UltraTemp ETI Hybrid Heater. As the first pool heater to combine a heat pump and gas-fired heater, the hybrid heater provides faster heat-ups by operating in gas-fired and heat pump modes simultaneously. It also has a unique hybrid mode that runs state-of-the-art programming logic to determine the fastest and most efficient way to heat the pool based on user input, water temperature differential, and time for optimal efficiency.

To limit the number of chemicals needed to treat the pool water Brunn opted for an energy-efficient ultraviolet light sanitizer, Pentair BioShield, to neutralize bacteria and reduce chlorine usage. Paired with a cartridge pool filter and robotic pool cleaner, the pool water is kept sparkling and clear.

Energy-efficient lighting and water features helped to create a backyard oasis, with the total experience connected with Pentair’s smart, automated technology. The Pentair IntelliCenter Control System allows Brunn to easily manage features, including lighting, temperature, chemistry, and water quality—from anywhere in the world.

Actual savings may vary based on local utility rates, pool size, pump run time, pump horsepower, pump rpm, plumbing size and length, pump model, service factor and other hydraulic factors. Individual Weighted Energy Factor (WEF) scores and savings may vary by model.
