An access control system, comprising: - a plurality of sensors that detect sensor data regarding a user; and - an access controller (1408, 1624) comprising one or more processors that: - receive credential data regarding the user from at least one of an access control device and an electronic wallet (13a, 13b), the credential data representative of a medical status of the user; - evaluate the medical status using at least one of the sensor data and the credential data, wherein evaluating the medical status using the sensor data is associated with intoxication or health parameters, such as temperature data and/or movement data, of the user, and evaluating the medical status using the credential data is associated with the user having immunity to, having been treated for or having been vaccinated for a medical condition; - validate access into a space responsive to the medical status being satisfied; - update a record data structure of at least one of the electronic wallet (13a, 13b) and a distributed ledger using the evaluation of the medical status; and - responsive to the evaluation of the medical status, modify an access control level associated with access to at least a portion of the space; and - a building controller configured to maintain a building data structure and to control operation of building components of the at least a portion of the space responsive to the evaluation of the medical status, using the building data structure, wherein the access controller (1408, 1624) and the plurality of sensors are configured to update the building data structure of the building controller. - a plurality of sensors that detect sensor data regarding a user; and - an access controller (1408, 1624) comprising one or more processors that: - receive credential data regarding the user from at least one of an access control device and an electronic wallet (13a, 13b), the credential data representative of a medical status of the user; - evaluate the medical status using at least one of the sensor data and the credential data, wherein evaluating the medical status using the sensor data is associated with intoxication or health parameters, such as temperature data and/or movement data, of the user, and evaluating the medical status using the credential data is associated with the user having immunity to, having been treated for or having been vaccinated for a medical condition; - validate access into a space responsive to the medical status being satisfied; - update a record data structure of at least one of the electronic wallet (13a, 13b) and a distributed ledger using the evaluation of the medical status; and - responsive to the evaluation of the medical status, modify an access control level associated with access to at least a portion of the space; and - a building controller configured to maintain a building data structure and to control operation of building components of the at least a portion of the space responsive to the evaluation of the medical status, using the building data structure, - receive credential data regarding the user from at least one of an access control device and an electronic wallet (13a, 13b), the credential data representative of a medical status of the user; - evaluate the medical status using at least one of the sensor data and the credential data, wherein evaluating the medical status using the sensor data is associated with intoxication or health parameters, such as temperature data and/or movement data, of the user, and evaluating the medical status using the credential data is associated with the user having immunity to, having been treated for or having been vaccinated for a medical condition; - validate access into a space responsive to the medical status being satisfied; - update a record data structure of at least one of the electronic wallet (13a, 13b) and a distributed ledger using the evaluation of the medical status; and - responsive to the evaluation of the medical status, modify an access control level associated with access to at least a portion of the space; and - a building controller configured to maintain a building data structure and to control operation of building components of the at least a portion of the space responsive to the evaluation of the medical status, using the building data structure,
