Abstract
The intent of this research effort was to better understand the intersection between mechanisms for improved indoor
air quality and the impacts to energy efficiency and operational building emissions. The results can be used to inform
program development and the design community on how to balance these two vital factors in the design and operation
of multifamily housing buildings.
The research included a literature review of supporting work on this or related topics. These findings were then used to
inform the development of a multi-part modeling effort. This included:
— indoor particulate modeling
— building energy modeling
— operating greenhouse gas emissions model based on
energy use and time-variant grid emissions
The study evaluated two main categories: existing affordable multifamily buildings and new affordable multifamily
buildings. Within each of these categories, three cases were studied. These were as follows:
E X ISTI N G BUI LDI N G
— Baseline - Typical multifamily housing building
— Retrofit - Addition of a portable HEPA filter unit
— Renovation - Extensive upgrades to building envelope
and HVAC systems
NEW BUI LDI N G
— Baseline - Code minimum multifamily housing building
— Energy Efficient - Above code HVAC system
efficiencies and envelope performance levels
— Energy Efficient +IAQ - Above code HVAC system
efficiencies and envelope performance levels with higher
air filtration levels and higher ventilation air capacity
