Energy Recovery Ventilators (ERVs) are considered a best-practice solution in multifamily building design. They optimize both ventilation and energy efficiency by transferring heat and moisture between incoming and outgoing air streams. However, in some projects, ERVs may not be included due to cost, space constraints, or design decisions. For projects without ERVs, it becomes especially important to…

Energy code compliance for multifamily building projects continues to increase in complexity. The 2021 and 2024 versions of the International Energy Conservation Code (IECC), now in effect in many states in the Mid-Atlantic and Northeast regions, contain new requirements that can significantly affect the design and budget of new multifamily buildings. To mitigate the impact…
