Sustainable Heating and Cooling: Innovative Water-Based Systems for Energy Efficiency

Heating and cooling systems account for a significant share of global energy use, making them a key focus for improving sustainability and reducing emissions. Conventional systems often rely on energy-intensive technologies that contribute to higher carbon footprints and operating costs. Water-based radiant systems offer a more energy-efficient and environmentally responsible alternative. Read how Denver Water is advancing sustainable heating and cooling through the use of radiant technology and integrated building design.

Water is a highly effective medium for transferring energy due to its superior heat capacity compared to air. Modern systems embed plastic tubing into structural components like floors and walls, circulating water at various temperatures to regulate indoor climates. This method helps reduce energy consumption, lowers operational costs, and minimizes reliance on fossil fuels, contributing to more sustainable operations.

Advanced systems often incorporate energy recovery mechanisms, capturing excess heat or cold from specific areas and redistributing it to meet demands elsewhere. Heat pumps play a key role, converting low-grade energy into usable forms for heating or cooling. Natural sources like mountain snowmelt or underground water supplies can also act as renewable cooling agents, enhancing efficiency during warmer months.

Complementary features, such as efficient insulation, smart windows, and tight building envelopes, further optimize energy performance. Together, these elements help reduce environmental impact while improving operational resilience.

Case Study: How Denver Water Uses Radiant Heating and Cooling for High-Performance Green Buildings

Denver Water’s new Administration Building incorporates a radiant heating and cooling system that highlights the potential of innovative climate control solutions. Unlike conventional forced-air systems, this approach uses water, a highly efficient energy transfer method, to regulate indoor temperatures.

The system uses plastic tubing in the building’s concrete slabs to circulate water at various temperatures, ensuring consistent indoor comfort year-round. Excess heat from the building’s southern exposure is repurposed for heating needs elsewhere, while mountain-sourced water provides cooling during summer months.

A Central Utility Plant located in the Trades Shop calibrates water temperatures using heat pumps, which recover low-grade energy from one part of the facility and convert it into usable heating or cooling energy. During summer, the system reverses this process to enhance cooling efficiency. Four pipes carrying chilled and hot water allow energy to be redistributed across multiple buildings within the complex, ensuring balanced climate control.

The radiant system reduces reliance on natural gas and minimizes grid electricity usage, making the Administration Building 30–50% more energy efficient than conventional designs. Additional features, such as efficient insulation, smart windows, and shading, complement the system, further enhancing performance.

Denver Water’s approach contributed to multiple buildings earning LEED certification, demonstrating how modern building design can align with energy efficiency and environmental stewardship goals.

The Take-Out

Innovative heating and cooling systems using water illustrate how sustainability can be integrated into building design effectively and efficiently.
