Glenstar, JLL and Affinius Capital Announce $12 Million Renovations and Significant Leasing Activity at Energy Square

DALLAS (May 13, 2026) - JLL, Glenstar and Affinius Capital today announce significant renovations are underway at Energy Square, a five-building, Class-A office campus located near University Park just across from SMU. Having undergone a $70 million upgrade to the office campus and amenities in 2019, forthcoming upgrades - including a premium coffee and full-service liquor bar, revamped outdoor terrace, large conference rooms with seating for 200 and a spec suite floor - are designed to further elevate and modernize the customer experience. JLL, which handles leasing activity at Energy Square, has executed 62 transactions totaling 188,000 square feet since early 2025.

Upcoming enhancements to Energy Square II will include a buildout of spec suites and new large conference rooms on the third floor, as well as full floor buildout of tenant-ready office spaces on multiple floors throughout the building, altogether totaling more than 100,000 square feet of available space for future customers. These renovations will introduce six new conference rooms designed to accommodate more than 200 occupants with a complimentary pre-function lounge area, ample room to host events, a high-end board room, and four state-of-the-art spec suites, prioritizing accessibility, collaboration and convenience for employees.

At Energy Square III, planned upgrades feature a new ground-level tenant lounge anchored by a cafe and bar concept, "Alter Ego." The space will serve coffee and tea during the day and alcoholic beverages in the evening, with seamless access to the expansive outdoor terrace, which will also be updated. Additions like increased greenery and comfortable seating, turf, planters and a fire pit will invite employees to collaborate, connect and reset outdoors during the work week. Award-winning architecture and design firm Gensler handled design for the $12 million Energy Square upgrades underway.

"Energy Square stands as one of Dallas's most compelling opportunities, combining world-class amenities, competitive pricing, and an unmatched customer experience," said Jeff Eckert, President, Agency Leasing at JLL. "Whether you're a corporate user seeking full-floor presence, a smaller customer wanting a spec suite, or a bespoke tenant wanting an elevated workplace, Energy Square delivers. This renovation doesn't just enhance the property - it solidifies Energy Square's position as the benchmark for forward-thinking office environments in Dallas."

Of 188,000 square feet transacted at Energy Square since January 2025, 114,000 square feet, or 29 deals were new tenants; and 74,000 square feet, or 33 deals, were renewals.

Located off U.S. 75 between Lovers Lane and University Boulevard, Energy Square is commuter friendly and features easy access to the Lovers Lane DART rail station, situated adjacent to the property. The campus is designed to support a strong work-life balance, and offers a variety of existing onsite amenities, such as one of the most pristine fitness centers in Dallas, conference facilities, outdoor spaces and several dining options, including recently opened Jake's Burgers.

To ensure the customer experience remains top of mind through every inch of the property, building ownership has appointed Brittany Mebust as Directory of Hospitality for Energy Square, a unique position to the Dallas market. Mebust will focus on key details to maintain a sophisticated environment reminiscent of a high-end hotel, as well as tailoring onsite events to align with the needs and preferences of the tenant base, boosting employee satisfaction, leasing potential, customer retention and recruiting efforts. Energy Square hosts nearly 100 events on campus each year and facilitates timely communication through the Energy Square app, all intended to build community across the campus.

"Energy Square represents exactly where the Dallas office market is heading: dynamic, experience-driven, and built around the needs of modern tenants," said Mickey Stefan, Principal at Glenstar. "These renovations are not just upgrades to the physical space, but a long-term investment in how people work, collaborate, and connect every day."

The upgrades at Energy Square reflect broader momentum in the Dallas office market. According to JLL's latest 2026 Q1 Dallas Office Market Report, the region recorded the second-highest population growth in the country, adding 123,557 residents in 2025. As Dallas continues to expand, demand for high-quality office environments is increasing in tandem.
