Cool SHade with a Purpose: Elevating 8 Willis Street Through Glass, Colour and Performance

The redevelopment of 8 Willis Street in Wellington, New Zealand, showcases a harmonious blend of heritage preservation and modern innovation. A key element in this transformation is the use of Cool SHade 57-1 on Clear Low-E Double Glazed Units (DGU) for the building's façade. This advanced glazing solution not only enhances the building's aesthetic appeal with its subtle grey tint but also significantly improves its energy performance, contributing to a sustainable and comfortable environment.

Cool SHade 57-1: A Fusion of Style and Efficiency

Cool SHade 57-1 is a high-performing neutral grey Low-E glass designed to offer superior thermal insulation while introducing a sophisticated grey hue. This tint adds a contemporary touch to the building's exterior, complementing the architectural vision of seamlessly integrating the new structure with the retained elements of the original 1980s building. The neutral grey tone provides a modern aesthetic without overpowering the design, ensuring that the building stands out subtly within its urban context.

Enhancing Energy Efficiency with Low-E Technology

Low-E (low-emissivity) glass features a microscopically thin, transparent coating that reflects infrared energy (heat) while allowing visible light to pass through. In Wellington's variable climate, this means the glass helps retain interior heat during cooler months and reflects exterior heat during warmer months, maintaining comfortable indoor temperatures year-round. This thermal regulation reduces the reliance on heating and cooling systems, leading to lower energy consumption and operational costs.

When incorporated into double-glazed units, the benefits are further enhanced. Double glazing consists of two panes of glass separated by an air or gas-filled space, providing additional insulation and soundproofing. This configuration not only minimizes heat transfer but also contributes to a quieter and more serene indoor environment, essential for the building's occupants.

Bringing 8 Willis Street to Life

The application of Cool SHade 57-1 on Clear Low-E DGU in the façade of 8 Willis Street serves multiple purposes:

• Visual Appeal: The subtle grey tint adds a modern and elegant touch to the building, enhancing its visual presence and reflecting the surrounding urban landscape.

• Thermal Comfort: The Low-E coating and double-glazed configuration work together to maintain stable indoor temperatures, ensuring a comfortable environment for occupants throughout the year.

• Sustainability: Improved energy efficiency aligns with sustainable building practices, reducing the building's carbon footprint and supporting Wellington's commitment to environmental responsibility.

The redevelopment of 8 Willis Street is more than just a structural upgrade; it represents a thoughtful approach to urban regeneration that respects the past while embracing the future. The strategic use of Cool SHade 57-1 on Clear Low-E DGU glass exemplifies how innovative material selection can breathe new life into urban spaces, creating structures that are as efficient as they are aesthetically pleasing.
