We met briefly with the HO manager and they have a 3 story with parking garage under the 3 floors that is heated.  The building has 2 entrances with meeting area in both foyers and the foyers are open all the way to top of building.

The HO manager says they have about $50,000 allocated for some upgrades and he wants to know if I as an energy auditor can give the 70 owners any suggestions to improve the comfort issues in this 50 yr old building.  We are thinking about doing a sample of some units to see what issues we find with blower door and thermal.  

Making some suggestions as a start.  They have all electric heat furnaces in each unit with AC roof tops. We know there is poured concrete between floors and older aluminum framed windows at this point.

Does anyone have any thoughts or suggestions on how to approach this project.

Where is this project located?

Try getting an energy modeler to perform an analysis of the building.

In California, we work on Multifamily projects and the California Building Code for Energy Compliance requires the use of the California Simulation Engine, either CBECC-RES or EnergyPro software to perform this type of analysis. There is a report called an ECON-2 report that can show your building's energy consumption as-is, then will allow you to explore various upgrades, showing the cost and the energy savings benefit for each measure.

Windows should be the last thing to upgrade in my opinion, unless the energy model shows that they would be the greatest benefit. With your budget, you might be interested in other strategies such as window overhangs, better insulation, etc. and focus on basic thermal comfort to help mitigate long term climate change- depending on what you think the largest issues are for the building.
