    Hello, Wise Ones. 


    Our museum is considering rolling the implementation of a new HVAC system into our 5 year strategic plan.  I am interested in feedback from those of you who have overhauled your institution's HVAC systems, particularly in what challenges you faced going into the overhaul, what was successful/unsuccessful about your project, and what facility support you have for maintaining your system.


    Thanks for any and all feedback.  I appreciate you all so much as a resource.


    Sincerely,

    Hi...

    Funny you should be asking about this.  My Dept. is finally in the midst of an HVAC replacement and upgrade.
    A number of unexpected items are coming to light, but the biggest one is dust in the ducts.  Make sure all of
    your valuables are well draped.!  The other item is to use the opportunity of replacement to make sure that
    all of your duct dampers are working and are correctly set.

    When the excitement is finally over, I'll be able to say more about this.

    Yours,

    Lyman

    ​Hello Tracy,

    Depending on what you want to do the implementation (either new or a replacement) of the HVAC can be a very involved project.  Some of the things you might want to consider doing are:
    1.  Start studying your options/plans/strategies now and the current system now.
         - try to get an historical understanding of your site and the different systems currently installed (or abandoned in place).  You will be managing the leftovers of previous projects whether you like it or not.
    2.  Involve as many departments/stakeholders as possible
         - members of the education, curatorial, facilities, administration, visitor services departments, etc.
         - engineers
         - architects
         - preservation specialists
         - neighbors or other members of the community nearby
         - board members
         - anyone else who might have insight or is invested in your site
    3.  Study your existing HVAC and come up with a plan to make it work better while your planning a new system
         - conduct an energy audit
         - conduct a staff procedures audit
         - if you don't have one make sure you have a systems operation manual for the existing system (keep in mind you want this created for the new system as well).
         - evaluate what you want the system to do in relationship to the historic structure, collection, and people
    4.  Evaluate and explore revenue sources (grants, loans, donations, etc.) that will offset the costs
    5.  Assess your collections and what the long term goals are for its care
         - evaluate storage space (keep onsite or offsite); if onsite what is the space like and how will the HVAC need to address the storage space
         - how are temperature and rh controlled now (are you adding rh controls that you don't have now?  If so, consider what effect that will have on the structure not just the collection)
    6.  Are there other projects in your strategic plan that need to take place first (or at the same time), e.g., do you need to preserve the windows and add storms to make it efficient?
    7.  Consider putting together an Owner's Project Requirements (OPR) document.  It sets out from the beginning what it is you want to accomplish with the new system and dictates the direction the project will go.
    8.  Consider a cost benefit analysis if you come up with different system options (e.g., geothermal vs. vrf)
    7.  Be prepared for surprises no matter how much you plan.

    There are a whole host of other issues to consider but if you have a good project team in place you should have a good handle on the project.  Remember no system is every going to be perfect but it helps to set the foundation now for the work later.

    Good luck.

    In a museum setting, HVAC systems are usually thought of in terms of climate and humidity control for the safety of the collections.  This is of course very important, but so are the live occupants of the facility. 

    I once worked in a brand new building with lab and lecture spaces that were nearly useless for teaching due to the excessive noise of the HVAC system.  Even those with perfect hearing struggled to hear instructors, and anyone with moderate or even slight hearing loss was left totally adrift. 

    The engineers made all of the airflow volume and efficiency calculations, but nobody ever thought about how it would sound in these spaces.  Getting a sonic environment suitable for the intended purpose of these rooms required a very costly retrofitting involving removal/replacement and modification of (new!) existing components.  This could have been avoided with more thoughtful design. 

        Cheers,

                  Michael
