When referring to a business, we know that human capital accounts for 90% of the total costs involved in keeping it running, including the management and maintenance of premises, energy costs, rent, etc. The medical-scientific evidence collected over 10 years by the International Well Building Institute demonstrate that with the implementation of WELL Certification measures, benefits such as:

Although most are for office spaces, The WELL Building Standard is also applicable to housing projects, educational centres, commercial premises and restaurants.. Furthermore, WELL Certification is applicable to buildings and their envelopes as well as to independent spaces within them. An example is the case of business headquarters located in an office building.

How much does the WELL Certification cost?
WELL Certification costs are divided into project adaptation costs, certification costs and advisory costs. Project suitability and advisory costs The requirements for WELL Certification are very similar to those of LEED or BREEAM Certification. However, the cost of certification is higher than that of other certifications. This is because the achievement of some of its credits is conditional on obtaining concrete results during the measurement process, which requires the existence of a Right then, Assessor. This Well Assessor, assigned by the GBCI, in addition to having an advisory role during the certification process, will be responsible for carrying out the final visit that will determine the achievement of WELL Certification.
Implementation
The additional cost for project adaptation, consultancy, and payment of the certification to the organisation WELL does not exceed the PEM's 2%. In fact, depending on the project, the cost overrun may be less than 11% of the project budget.
Savings
Referring to residential buildings, a study in the USA has shown that Homes certified under the WELL scheme have seen their value rise by 20%. Likewise, their operating costs are reduced due to a series of measures that allow them to better take advantage of environmental conditions.
In the case of offices, the most appropriate way to evaluate the cost of implementing the WELL Building Standard is by contrasting it with the Cost savings from personnel expenses. These savings are due to increase in employee health, wellbeing, and motivation levels. We must highlight that, in 2019, absenteeism from work due to stressful working environments alone resulted in losses of over 7 billion euros for Spanish companies. This must be added to the fact that, under the conditions of COVID-19, these losses increased to 8 billion in 2020.
