PHIUS launches multifamily resource center

Multifamily developers who want more information about the design, financing, and execution of PHIUS+ certified projects have a new place to go.

Passive House Institute US (PHIUS) has released the PHIUS Multifamily Resource Center, an online repository of information, tools, case studies, and best practices to support

The release of the climate-specific, cost-optimized PHIUS+ 2015 Passive Building Standard in March of 2015 by PHIUS ignited the tremendous growth of passive building from coast to coast, with the most significant gains occurring in the multifamily housing sector.

PHIUS+ Certified and Pre-Certified projects now total more than 1 million square feet across 1,200 units nationwide.

The PHIUS+ 2015 Standard makes passive building affordable by targeting the sweet spot between investment and payback to present a cost-effective solution to achieving the most comfortable and efficient building possible for a given climate and location, while also offering the best path for achieving zero energy and carbon.

The resulting building performs 60%-85% better (depending on climate zone and building type) on an energy consumption basis when compared to a code compliant building (International Energy Conservation Code IECC 2009), due to heating and cooling load reductions of 86% and 46% respectively on average over all climates and an overall site EUI of 10-20 kBTU/ft2 per year.

Developers pursuing certification under the PHIUS+ 2015 Standard report a cost premium for passive building methods at approximately 0-3% over a standard Energy Star construction baseline. In fact some developers even report a negative cost premium for passive building since the high-performance enclosure allows for the reduction in mechanical system size and equipment, thereby reducing both first costs and operational expenses for the life of the building.

Katrin Klingenberg, Executive Director of PHIUS, is thrilled about the release of the new multifamily website for developers. “We have finally reached the tipping point with the PHIUS+ 2015 Standard so that building to passive building standards can be more cost-effective than business as usual construction practices. The PHIUS Multifamily Resource Center will help to make even more of these projects a reality.”
