Gallery: Colorado’s State Capitol is the First and Only LEED Certified ...

Because of the richly historic nature of the building, the energy upgrades cannot disturb its character. This means that the HVAC systems are a mixture of new boilers and chillers, old radiators and ducts, and retrocommissioning. One example of energy savings is how, by taking advantage of the thermal mass, engineers can flush excess heat that the building gained throughout the day out at night.

The state has successfully saved 30% of their energy demand a year or $1.3 million annually, enough savings to fund the retrofits outright. As upgrading existing buildings becomes a paramount duty to lower our energy usage, our government can become essential in leading the way by showing the value of this endeavor. Luckily old buildings like the Colorado State Capitol are actually more energy efficient than most modern buildings and only need TLC and some creative thinking to make them high performance spaces. The next project is to install a $4.6 million dollar geo-source heat pump for the complex that will guarantee great savings for another generation.
