Crystal Lagoons® Technology: Leading a Green Revolution in Real Estate and Hospitality

• The patented method developed by the multinational water innovation company reuses waste heat from data centers and other technological infrastructure to sustainably heat crystalline lagoons, transforming an energy byproduct into real estate value.

In a world driven by artificial intelligence, cloud computing, and digitalization, data centers have become essential infrastructure. However, they also face a growing challenge: the waste heat generated by their servers and technological equipment.

Crystal Lagoons® found an innovative answer to this problem. Through its patented method, Eco-Heated Lagoons by Crystal Lagoons™ reuses waste heat from data centers, crypto mining facilities, and other technological infrastructure to sustainably heat crystalline lagoons.

The proposal turns an energy byproduct into a source of value for real estate, tourism, and hospitality projects. It is not just about heating water: it is about transforming an operational challenge into a competitive advantage for the real estate sector.

The challenge: waste heat and real estate differentiation

Data centers operate continuously and generate large amounts of heat. Traditionally, that heat must be dissipated through cooling systems, often involving high energy consumption.

At the same time, real estate developers face another challenge: creating more attractive, sustainable, and differentiated projects, especially in markets where traditional amenities no longer generate enough perceived value.

Eco-Heated Lagoons by Crystal Lagoons™ connects both worlds: it harnesses waste heat and turns it into a year-round beach lifestyle experience.

The patented method of Crystal Lagoons®

Eco-Heated Lagoons by Crystal Lagoons™ technology is based on a patented closed-loop system that captures waste heat produced by technological facilities and transfers it to the lagoon, using the water as a thermal dissipator.

How does it work?

1. Waste heat capture

Servers and technological equipment generate heat during operation. Instead of wasting it, the system recovers it as a useful thermal source.

2. Closed-loop heat transfer

Through the patented method of Crystal Lagoons®, that heat is efficiently transferred to the lagoon system.

3. Creation of heated beach areas
   Heated water enables the development of recreational areas with comfortable temperatures, extending the season of use and transforming the lagoon into an active year-round destination.

Why it is a sustainable solution

The sustainability of Eco-Heated Lagoons by Crystal Lagoons™ is based on a simple principle: harnessing existing energy.

Instead of generating heat from scratch, the technology reuses waste heat from infrastructure that operates continuously. This helps reduce the need for additional energy to heat large bodies of water while also providing an efficient alternative for dissipating heat.

Key sustainable benefits

• Waste heat reuse: transforms an energy byproduct into a source of value.
• Reduced need for additional energy: lowers dependence on traditional heating systems.
• Operational efficiency: turns the lagoon into a large-scale heat dissipator.
• Contribution to ESG criteria: enables innovation, efficiency, and sustainability to be integrated into the project.
• Year-round use: improves the profitability of amenities that could previously depend on seasonality.

Benefits for real estate developers

Eco-Heated Lagoons by Crystal Lagoons™ not only addresses an environmental challenge. It also opens up new commercial opportunities for real estate and hospitality projects.

1. Extends the season of use

A heated lagoon allows residents, guests, or visitors to enjoy a beach experience even during colder months, increasing the amenity’s utility.

2. Strengthens the project’s positioning

Offering a heated crystalline lagoon with sustainable technology enables developers to build a powerful commercial narrative: year-round beach lifestyle, real innovation, and environmental commitment.

3. Creates a destination

The Eco-Heated Lagoons by Crystal Lagoons™ model can become the heart of the project: a gathering point for recreation, wellness, and social life.

4. Increases perceived value

Today’s consumers seek memorable experiences. A heated lagoon sells more than square meters; it sells a way to live, relax, invest, or vacation.

5. Connects real estate, technology, and sustainability

Integration with data centers or other technological infrastructure makes it possible to create more efficient urban ecosystems, where waste heat ceases to be a problem and becomes a resource.

Applications in real estate and hospitality

The versatility of Eco-Heated Lagoons by Crystal Lagoons™ allows this technology to be applied across different types of projects:

• Master-planned communities.
• Multifamily developments.
• Hotels and resorts.
• Mixed-use projects.
• Public Access Lagoons® developments, also known as PAL® projects.
• Tourism projects in cold climates.
• Developments located near data centers or technology hubs.

The future of sustainable amenities

The real estate industry is entering a new stage. Amenities can no longer be merely decorative: they must provide utility, differentiation, commercial value, and environmental coherence.

Eco-Heated Lagoons by Crystal Lagoons™ responds to that demand. Its patented method demonstrates that waste heat can be transformed from an energy loss into a tangible, profitable, and sustainable experience.

For real estate developers, the opportunity is clear: to create more attractive projects, extend their operation year-round, and offer a value proposition that connects technological innovation with a beach lifestyle.

Waste heat no longer has to be wasted. With Crystal Lagoons®, it can become turquoise waters, heated beaches, and a new generation of sustainable amenities.

• LeFrak and Turnberry placed a lagoon powered by Crystal Lagoons® technology at the heart of the Solé Mia development. The project has achieved occupancy rates of up to 99%, earned international awards and commands up to US$1,800 more in monthly rent per unit.

In North Miami, one development fully leased its first tower in just three months. Today, it commands up to US$1,800 more in monthly rent per unit than neighboring properties. And it was built, quite literally, on a former landfill. Its name is Solé Mia, and its story is a must-read case study for any developer looking to stand out in an increasingly competitive market.

The key to it all is a 6.61-acre lagoon powered by Crystal Lagoons® technology, the first of its kind in South Florida.

A Project That Lives Up to Its Creators

Solé Mia is no ordinary development. It is backed by LeFrak and Turnberry, two of the most respected names in U.S. real estate, bringing a rare level of experience and credibility to the project.

LeFrak has more than a century of experience and a portfolio of over 400 buildings. Turnberry has spent more than 50 years creating residential, commercial and hospitality destinations, and manages a real estate portfolio valued at US$10 billion.

The project’s numbers speak for themselves:

• 184-acre master plan in North Miami
• Estimated investment of US$4 billion
• Up to 12 planned residential towers, with more than 6,000 approved units
• Four completed towers totaling 1,473 units, with a fifth under construction
• Schools, a medical center, retail, offices and resort-style amenities integrated into the master plan

It is, quite simply, a city within a city. And at the center of it all is a lagoon created by the multinational water innovation company.

The Numbers Speak for Themselves: Unprecedented Returns

For developers, good ideas are measured by their return on investment. The crystalline lagoon became the centerpiece of the project, and the financial results prove the strategy worked:

• Near-full occupancy: The project maintains occupancy rates of between 96% and 99%. Units overlooking the lagoon are in the highest demand.
• Rental premium: Solé Mia commands rents 15% to 25% above market rates for comparable properties in North Miami.
• Additional income per unit: That premium translates into monthly rents of up to US$1,800 more per unit.
• Direct comparison: While a two-bedroom apartment in North Miami typically rents for between US$2,400 and US$2,800 per month, comparable units at Solé Mia command between US$3,300 and US$4,200.

The Quote That Says It All

Richard LeFrak, who leads one of the largest real estate companies in the United States, does not make a habit of speaking in superlatives. That gives even more weight to what he said about the leasing of the project’s first tower:

“The Shoreline at Solé Mia is the fastest and most successful rental lease-up in the company’s 100-year history of real estate development.”

When the Media Takes Notice

The Miami Herald, one of Florida’s most influential news outlets, described Solé Mia as a “neighborhood game changer.” It was more than a headline: within three months of its January 2019 launch, the project’s first tower was 100% leased.

Financial Times and Bloomberg have also covered the project, citing it as a benchmark for innovation in large-scale, mixed-use communities. Residential developments do not often capture the attention of global financial media, but Solé Mia did, thanks to one clear differentiator: its crystalline lagoon.

A Development Designed for Every Type of Resident

Another strength of Solé Mia is its ability to attract very different segments through a shared value proposition:

• Families looking for larger units, club-style amenities and a safe environment
• Young professionals and couples drawn to studios and one-bedroom apartments designed for an active lifestyle
• Students and short-term renters who prioritize connectivity and social life
• Seniors who value tranquility, wellness and access to healthcare

That versatility is precisely what makes the lagoon a unifying amenity across every resident segment. Everyone uses it. Everyone values it. And that translates into sustained occupancy across the entire product mix.

From Contaminated Land to an Urban Icon

Perhaps the most remarkable part of Solé Mia’s story is where it began. The site was a former landfill, a contaminated site that was virtually unusable under a conventional development model.

Through an Opportunity Zone strategy and an extensive environmental remediation process, LeFrak and Turnberry transformed the property into one of Miami’s most sought-after developments.

Crystal Lagoons® technology made it possible to build a crystalline lagoon for watersports, white-sand beaches and an active waterfront community on that very site.

The development continues to grow. It recently added the first floating pickleball court installed on a residential lagoon in the United States, another example of how the lagoon remains a platform for creating new amenities.

An Award-Winning and Exclusive Ecosystem

Solé Mia is more than a commercial success. It has become a benchmark for design and sustainability, earning some of the industry’s most important honors for its transformation of this urban site.

The project received the 2020 World Design Award for Best Landscape Design Built, presented by The Architecture Community. That same year, it won the Golden Novum Design Award for Urban Planning and Landscape Design.

The model works because it intelligently combines white-sand beaches and watersports with essential services such as a UHealth medical center, schools, coworking spaces and retail areas. It attracts families, young professionals and students—all looking for an urban resort lifestyle.

Solé Mia’s formula is clear. Integrating a lagoon powered by Crystal Lagoons® technology is not simply a landscaping expense. It is a highly replicable business strategy for urban multifamily markets looking to create real value, stand out from the competition and secure long-term profitability.

• The hospitality industry is increasingly competitive, demanding amenities that create unique experiences. Small Lagoons by Crystal Lagoons™ offers a new way to stand out, attract guests, and maximize a development’s potential.

For decades, a swimming pool has been almost a must-have for hotels and resorts. But the market has changed. Today, having a pool doesn’t necessarily set a property apart. Guests are looking for spaces that surprise them, offer different ways to enjoy their stay and, of course, make them want to take photos and share the experience.

That’s where a new alternative for the hospitality industry comes in: compact lagoon amenities.

Small Lagoons by Crystal Lagoons™ brings the appeal of a turquoise-water lagoon and white-sand beaches to spaces ranging from 500 m²/ 5,400 sq ft to 4,000 m²/ 1 acre. Designed for real estate and hospitality developments, the concept makes it possible to create a beach-style experience even where space is limited.

From a Pool to an In-Hotel Destination

The visual impact is immediate. Resort pools tend to follow a familiar formula. A lagoon creates something entirely different, transforming the space into a destination in its own right.

The combination of turquoise waters, white-sand beaches, and inviting areas to relax and unwind creates an atmosphere that feels more like a vacation destination than a traditional hotel amenity. That makes a real difference in hospitality, where guests often form their first impression long before check-in—through a photo on a hotel website, booking platform, or social media.

For a developer, the result is an asset that’s not just for swimming. It can become a defining feature of the property and one of its most compelling selling points.

Small Lagoons by Crystal Lagoons™ was created with this goal in mind: to help projects stand out and boost sales and occupancy by offering an experience centered around turquoise waters, white-sand beaches, and the beach lifestyle.

What Does the Guest Experience?

• A greater sense of space.
• The feeling of being at a beach destination.
• Areas designed for different groups and ages.
• More memorable, shareable experiences.

More Experiences in Compact Water Spaces

One of the main advantages over traditional swimming pools is the range of experiences that can be created in and around the water.

These smaller-scale lagoons from the multinational water innovation company combine white-sand beaches, relaxation areas such as the Lagoon Lounge, recreational spaces, and water sports. This allows a single amenity to appeal to different types of guests and offer different experiences throughout the day. The technical materials of Crystal Lagoons highlight this distinction compared with commercial swimming pools, which are primarily designed for swimming.

For hotels and resorts, this opens up new possibilities: turning limited space into a place where guests want to spend more time, rather than simply taking a swim and moving on.

A Different Approach to Costs

The appeal of compact man-made lagoons goes beyond aesthetics.

Small Lagoons by Crystal Lagoons™ uses a liner system that eliminates the need for the periodic repainting often required by commercial swimming pools. Its ultrasonic flocculation technology also eliminates the need for large centralized filtration systems and the mechanical rooms they require.

For hospitality developers, the difference is particularly significant in three key areas:

• Lower construction costs: A Small Lagoons by Crystal Lagoons™ project can be significantly less expensive to build than a commercial swimming pool of the same size.
• Lower maintenance costs: Maintenance expenses can be as little as one-third of those associated with a traditional commercial pool.
• Lower hydraulic equipment replacement costs: The system helps reduce one of the significant recurring expenses associated with conventional swimming pools.

There are also broader benefits for hospitality developers:

• Stronger differentiation from competing properties.
• Greater appeal to potential guests.
• Higher perceived value for the development.
• More opportunities to strengthen marketing and sales strategies.
• A distinctive visual centerpiece that can become an icon for the property.

The New Standard in Recreational Amenities

The hospitality industry is constantly evolving to meet the expectations of increasingly discerning travelers. In this environment, recreational amenities need to offer much more than basic functionality.

Small Lagoons by Crystal Lagoons™ represents a new generation of water attractions: spaces designed to create memorable experiences, strengthen a project’s value proposition, and turn an amenity into a strategic asset.

For hospitality developers looking to stand out, attract more guests, and make their properties more appealing, the question is no longer whether a compact lagoon can replace a swimming pool. The real question is how much added value it can generate.
