Critique & Recommendations

Air

• Lumnia Building could look towards enhancing ventilation through the installation of operable windows which allows occupants to have access to fresh outdoor air. [A07.1 and A07.2]

• Instead of conducting annual indoor air quality audits, installing real-time air monitors would provide greater resolution of the indoor air quality within the premises. The monitors should measure at least 3 of the following parameters: PM2.5 or PM10, carbon dioxide, carbon monoxide, ozone, nitrogen dioxide, total VOCs and Formaldehyde. [A08.1]

Water

• There was a lack of information regarding Lumnia Building's efforts towards meeting the thresholds for drinking water taste and hygiene support. Meeting these 2 parameters would have helped them achieve full marks under Water. [W04 and W08] 

Light

• Task Lighting Integration: Provide individual, adjustable task lighting at workstations to allow users to personalize their light levels and reduce eye strain. Also Specify glazing that selectively transmits beneficial wavelengths of daylight while filtering out harmful UV radiation [L04.1]

• Daylight Zoning: Design spaces with "daylight zones" closer to windows for tasks needing high light and "transition zones" further in, with layered artificial light. [L05.1]

• Circadian Lighting System: Implement a tunable white lighting system that automatically adjusts color temperature and intensity throughout the day to support occupants' circadian rhythms. [L08.1] 

• High CRI and Low Flicker: Mandate light fixtures with a high Color Rendering Index (CRI >90) for accurate color perception and low flicker rates to minimize headaches and fatigue. [L08.1, L08.2] 

Sound

• Perform Reverb Time Analysis: Conduct thorough acoustic measurements in various spaces (open-plan offices, conference rooms, lobbies) to confirm whether reverberation times meet WELL thresholds. [S04.1]

• Assess High Traffic Areas: Identify corridors, meeting rooms, or break areas that experience consistently high foot traffic or noise. [S05.1]

• Add/Upgrade Materials: Consider carpeting or carpet tiles with acoustic underlay, wall coverings with high NRC (Noise Reduction Coefficient), and acoustic ceiling tiles to reduce ambient noise. [S05.1]

• If spaces are too quiet (leading to distraction from intermittent noises), a subtle sound masking system can maintain speech privacy and consistent ambient noise. [S06.1]

Thermal Comfort

• Radiant systems can significantly enhance comfort with surface temperatures are controlled to avoid discomfort (e.g., excessively hot or cold floors) and coordinated with humidity control measures to prevent condensation. [T05.1, T05.2]

• Improve thermostat control with individual thermostats are located within each office zone, allowing occupants to adjust the temperature like central system maintains a base temperature, while occupants can fine-tune using personal comfort devices. [T03.1]

Materials

While the Exeo/Lumnia Office Campus demonstrates sustainability practices aligned with LEED Gold, publicly available information does not confirm compliance with WELL’s stricter VOC thresholds or material health requirements. To fully meet WELL standards, the project would need to:

• Use WELL-recognized certified products for all wet-applied materials and furniture. [X05.1, X05.2]

• Submit third-party verified documentation during a WELL audit. [X07.1, X07.2, X07.3]

Nourishment

• The readily availability of a wide variety of foods in the over 60 restaurants in close proximity could overwhelm the availability of healthier choice foods.

• Healthier foods being available do not commensurate with healthier eating habits.

• Consumers do not always read labels even if available.

• Lack of studies to show improvement in occupants' health owing to achieving the Nourishment parameter.

• Vendors may change, along with choices of foods and beverages over time.

Movement

• While physical design cues are excellent, the level of occupant programming (e.g., group walks, movement challenges, or educational workshops) could be more robust to sustain engagement. [V06.1]

• Even though stairs are encouraged, some tenants or visitors may still prefer elevators if stairs aren’t presented as the default. Wayfinding might be further refined, with multi-lingual or icon-based prompts for an international tenant mix. Consider aesthetic touches - artwork, natural lighting, or music - to make stairs more than just a functional alternative. [V03.1]

• Partner with local gyms, fitness studios, or wellness coaches in the Parque das Nações area to provide on-site classes or discounted memberships. This further embeds a health-oriented culture into the tenant community. [V08.1]

• Convert or designate underused indoor spaces for casual physical activities (e.g., a small fitness corner, stretching area, or mindful movement zone). [V08.1]

Mind

• Quiet Rooms: Designate quiet rooms where occupants can go to relax, meditate, or escape from noise and stimulation. These rooms should have soft lighting, comfortable seating, soundproofing and calming colors. [M03.3, M03.4, M05.1]

• Mindfulness/Meditation Space: If possible, provide a dedicated space for guided meditation or mindfulness practices. [M03.3, M03.4, M05.1]

• Breakout Spaces: Design a variety of breakout spaces that offer different levels of stimulation and privacy, allowing occupants to choose environments that suit their needs. [M03.3, M03.4, M05.1]

• Acoustic Comfort: Go beyond general noise control. Design for speech privacy in workspaces and meeting rooms to minimize distractions. [M05.1]

• Ergonomic Design: Ensure that furniture and lighting support cognitive tasks and reduce mental fatigue. [M06.1]

• Cognitive Restoration Zones: Create areas designed to facilitate creative thinking and problem-solving, with access to natural light and views. [M07.1]

Community

• The distribution of the WELL Feature Guide is commendable but lacks dynamic updates or interactive platforms for ongoing education. Develop a digital wellness portal with real-time air/water quality data, ergonomic tips, and event calendars. [C01]

• While LUMNIA provides cycling infrastructure and water dispensers, it lacks on-site health services such as flu vaccinations or preventive screenings. With primary care services being one of the essential component of community, this can be explore through local clinics that offer quarterly health screenings. [C05]

• Although LUMNIA features gardens and squares designed for gatherings, there are no structured programs to foster community partnerships or tenant-led initiatives. A recommendation to launch a tenant-led committee to organize community events such as sustainability workshops or cultural festivals. [C11]

•  The building’s green spaces are accessible but may be underutilized. Possible collaboration with NGOs in hosting skill-sharing sessions (e.g., gardening, nutrition) in EXEO’s gardens. [C16]
