Lima already has a solid base of LEED and EDGE buildings, but that standard certifies the building, not what happens to the people inside it. Peru faces one of the highest rates of absenteeism and turnover in the region — workplace climate surveys in Lima rank stress and burnout among the top causes of resignation in banking, mining, and services. The same investment funds and multinationals that already require LEED for their environmental reports are starting to ask for evidence that the building protects human capital's health — the metric their HR departments and ESG reports under the social pillar (the "S") need to show. WELL, administered by the International WELL Building Institute (IWBI) and verified by GBCI — the same body that certifies LEED — is the standard that answers that demand with real performance testing: air quality, water quality, and lighting comfort measured on site, not just designed on paper.
Concept diagnosis: we assess the 10 WELL v2 concepts (Air, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind, and Community) and prioritize the ones with the highest impact and lowest cost for your building.
Registration on the IWBI platform: we register the project and define the target level — Bronze, Silver, Gold, or Platinum — based on budget and asset type.
On-site performance testing: unlike LEED, WELL requires real performance verification — air and water quality tests carried out by an accredited performance testing agent — before the certificate is issued.
GBCI certification and three-year recertification: once the seal is granted, we coordinate the recertification cycle WELL requires every three years, something neither LEED nor EDGE demands.
IWBI structures its registration and certification fees by built-area range, similar to how GBCI does it for LEED. The main difference in total cost is on-site performance verification — air and water quality tests carried out by an accredited performance testing agent — which WELL requires and LEED's process does not include, which usually makes WELL's budget higher for comparable square footage. The full process, including the performance testing period, takes an average of 12 to 18 months from registration. Unlike LEED, WELL certification isn't permanent: it requires recertification every three years to keep the seal active.

LEED assesses the building's environmental impact: energy, water, materials, and site. WELL assesses the building's impact on the health and performance of the people inside it, with on-site air and water testing. They're complementary: most WELL buildings worldwide already have or are pursuing LEED in parallel, and both share technical documentation that lowers the cost of certifying both.

Being among the first is the advantage. In markets where certification is still scarce, WELL differentiates a building more visibly than in saturated markets. Multinational companies based in Lima that report under GRESB or CDP standards are already seeking assets with this credential, and few buildings can offer it today.

Yes. WELL v2's New and Existing Buildings and Interiors pathway is designed to certify buildings in operation without major renovation, adjusting cleaning protocols, air quality, drinking water, and staff wellness policies.
