The condo building known as the Baptista could produce nearly as much energy as it consumes.

While newly built houses and condos must meet required standards for energy efficiency, the four-unit condo building at 523-525 Montana Ave. NE is designed to qualify for the highest level of green certification. Known as the Baptista, the condo developed by Tanya Topolewski of True Turtle could achieve a “passive house” designation, which means the building has the potential to produce nearly as much energy as it consumes.

Green features include an airtight building envelope and energy-efficient systems that allow the building to use 90 percent less energy for heating and cooling than an existing, similarly sized property. The Baptista is built to meet the Energy Department’s Indoor airPlus standard, which includes equipment, filtration and selection of finish materials to reduce contaminants that can lead to poor indoor air quality.

The lower-level units have double-height ceilings.

The first two units, available now, are Unit A in 525 Montana Ave. NE, a 2,400-square-foot residence with three bedrooms, a den and four bathrooms priced at $979,000, and Unit B in 525 Montana Ave. NE, a 1,900-square-foot unit with three bedrooms, a loft and four bathrooms priced at $799,000.

The condos have open floor plans and quartz waterfall-edge counters, tile backsplashes, gas cooking and stainless-steel appliances in the kitchens. The lower-level units have double-height ceilings with a wall of windows, a loft and a private patio. The upper-level units have a deck off the kitchen and a private rooftop deck with a bathroom.

A waterfall countertop is the centerpiece of the condos' open floor plans.

Residents can walk to the Brookland or Rhode Island Avenue Metro stations and shops and restaurants in Brookland and Edgewood, where plans are in place for future development. The neighborhood is also served by several bus routes.
