When beginning to consider thermal conditioning systems, review which system types will not only meet credit requirements, but will balance performance, efficiency and cost while creating an optimal thermal environment in the given climatic region. In some regions, direct evaporative cooling may be an appropriate option, while in others dehumidification may be needed to meet the credit requirements. Review the feasibility of natural ventilation systems versus mechanical systems and consider their effect on energy use, programming, and credit achievement.
Determine which HVAC system types (mechanical, mixed mode, or natural) and system components can best meet the credit requirements and review any special programming requirements for ventilation, humidity and thermal conditions. For example, consider whether in-floor radiant heating is preferable to forced-air systems and which are best suited to a project’s programming and budget, and confirm that the system will be capable of operating within the established comfort zone.
Review how building systems might contribute to or hinder achievement of this credit and review site-specific conditions that will affect building conditioning.
This credit is not about redesigning your base building to fit the needs of the tenants; however, encouraging building management to make improvements benefits both the building and the tenants.
It is helpful to discuss potential changes early in lease negotiation so that building management has time to decide on and implement needed changes by the time your CI project is complete.
If Option 2 paths are not applicable to your building, discuss the possibility of retrofitting and completing renovations to incorporate applicable changes, particularly if the owner already has renovations or maintenance scheduled. Target easy-to-implement points like flushometers, faucet aerators, reflective roof specifications, and irrigation updating strategies.
Hold a meeting with the tenant, clients, architects, and base building management to discuss each Option 2 path and potential base-building changes needed to earn those options.
Identify a representative from building management who can be contacted for details, documents, and specifications needed to document your chosen paths.
