Trinity College Dublin’s Business Campus, spanning 11,400 square meters, aimed to set a new standard for sustainable building design while providing a conducive environment for learning and working. The challenge was to create a heating, cooling, and ventilation system that not only met stringent energy efficiency targets but also maintained optimal indoor air quality without compromising the aesthetic appeal or obstructing the panoramic views through the perimeter glazing.

The Challenge

  1. Energy Efficiency: Achieving near-zero energy performance in accordance with the nZEB Directive while maximizing the use of natural resources and minimizing environmental impact.
  2. Aesthetic Integrity: Integrating sustainable heating, cooling, and ventilation solutions seamlessly into the architectural design to preserve the visual appeal and transparency of the building’s perimeter glazing.
  3. Indoor Air Quality: Ensuring optimal indoor air quality and occupant comfort by maintaining CO2 levels at 1000 parts per million (ppm) without compromising on ventilation efficiency or aesthetic considerations.
  4. Space Optimization: Maximizing available floor space and minimizing heat loss while countering draughts from glazed windows through innovative heating and ventilation solutions.

The Solution

Versatile Heating, Cooling & Ventilation collaborated with Trinity College Dublin to implement a holistic approach to sustainable design and engineering. The solution included:

  1. Trench Heating System: Below-floor trench heaters were installed to provide efficient heating, cooling, and ventilation tailored to respond to CO2 levels. These systems maintained indoor air quality at 1000 ppm while optimizing floor space and preserving unobstructed views through the perimeter glazing.
  2. Passive Design Features: The building incorporated passive design features such as double-skin facades and atrium ventilation to maximize natural light and ventilation, thereby reducing energy consumption and promoting occupant well-being.
  3. Low-Energy Ventilation Systems: Supplementing passive design, low-energy ventilation systems were integrated to ensure consistent indoor air quality and thermal comfort while minimizing energy consumption and maintenance requirements.
  4. Renewable Technologies: The project utilized renewable energy technologies to further enhance energy efficiency and reduce environmental impact, aligning with Trinity College Dublin’s commitment to sustainability.
