Trinity Lobby.

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. Indoor air quality: Ensuring optimal indoor air quality and occupant comfort by maintaining CO2 levels at 1,000 parts per million (ppm) without compromising on ventilation efficiency or aesthetic considerations. Space optimisation: Maximising available floor space and minimising heat loss while countering draughts from glazed windows through innovative heating and ventilation solutions. THE SOLUTION 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 1,000 ppm while optimising floor space and preserving unobstructed views through the perimeter glazing.

Passive design features: The building incorporated passive design features such as double-skin facades and atrium ventilation to maximise natural light and ventilation, thereby reducing energy consumption and promoting occupant wellbeing. Low-energy ventilation systems: Supplementing passive design, low-energy ventilation systems were integrated to ensure consistent indoor air quality and thermal comfort while minimising energy consumption and maintenance requirements. Renewable technologies: The project utilised renewable energy technologies to further enhance energy efficiency and reduce environmental impact, aligning with Trinity College Dublin’s commitment to sustainability.

When Trinity College Dublin aimed to set a new standard in sustainable building design with its 11,400sqm Business School, Versatile Heating, Cooling & Ventilation was appointed as supplier. Working alongside Scott Tallon Walker Architects and mechanical contractor IN2 Engineering Design Partnership, Versatile was charged with implementing a holistic approach to sustainable design and engineering. As well as providing a conducive environment for learning and working, the challenge was to create a heating, cooling and ventilation system meeting stringent energy efficiency targets and maintaining optimal indoor air quality without compromising the aesthetic appeal or obstructing the panoramic views through the perimeter glazing. THE CHALLENGE Energy efficiency: Achieving near-zero energy performance in accordance with the nZEB Directive while maximising the use of natural resources and minimising environmental impact.
