Philadelphia, PA

wynneThis 51-unit apartment building for seniors in West Philadelphia was built on the site of the former Wynne Theater reflecting the historic theater's shape and mass. It was also designed to be among the first multifamily Passive House developments in Pennsylvania. Innova served as the owner's project manager, Energy Star Rater and PHUIS Verifier. The building performed 20% better than the rigorous Passive House standard of 0.6ACH@ 50pa for air leakiness.

limekilnThis all-electric, wood framed construction, 200-unit family development built in 1979 in one of Pennsylvania's coldest climates was conditioned with expensive electric resistance heating and leaky through-wall air conditioners; the units were uncomfortable and expensive places to live, with poor indoor air quality and deteriorating building assemblies. Innova found that disconnected bath exhaust fans were pumping moist air into the poorly ventilated roof cavity, causing mold growth and premature inside-out rotting of the buildings' wood siding. Innova installed high-efficiency heat pumps and new Energy Star® bath fans, re-skinned the buildings with a water-managed rain screen cladding, and insulated and air sealed the aging building enclosure. The result was a stabilized building enclosure, improved indoor air quality and significantly lower HVAC operating costs.

Philadelphia, PA

academyThis mid-rise apartment building for seniors, constructed in 1982, suffered from a multitude of energy and indoor air quality issues, including poorly-drafting and inefficient atmospheric boilers, a failed rooftop make-up air unit and overheating of upper-story apartments. Innova managed this $400,000-plus pilot project for the City of Philadelphia's Weatherization Program, which included installing high-efficiency, sealed-combustion condensing boilers for space and domestic water heating, thermostatic zone valves in each apartment and VFD-controlled circulation pumps. Innova teamed up with Building Science Corporation to devise a load-neutral solution to the lack of building ventilation, whereby corridor and apartment ventilation were decoupled and fresh air introduced by an innovative indoor/outdoor air mixing system.

Lansdale, PA

academyThis complex of 10 two-story buildings containing 48 apartments was built in 1933. The original oil-fired heating and hot water boilers had been replaced since the site's construction, but continually increasing fuel oil prices and the systems' generally poor operating efficiency made their continued operation untenable. The Innova audit team found that a peaked roof assembly, added to the buildings' original roofs in the 1980s, had created a secondary cavity above the living spaces which acted as a thermal bridge to the un-insulated attic, accelerating heat loss through the building's thermal control layer. Innova produced a scope of work that included replacement of the existing oil-fired boilers with an array of modular condensing natural-gas-fired units. The secondary roof cavity was thermally-decoupled from the exterior to create an effective thermal control layer in the roof assembly. These measures, coupled with lighting and boiler pump efficiency retrofits, resulted in the reduction of annual energy usage by 46%.

academyThese wood frame townhouses were newly built in the 1990s as affordable housing. The cladding was acrylic stucco over OSB sheathing. 15 years later, the stucco finish looked as good as the day it was installed, but there was evident moisture coming inside the homes, suggesting that the wall assembly was accepting and storing bulk moisture. Innova cut discrete holes in the stucco cladding to take moisture readings of the sheathing. Nearly all of the wall assembly was wet, some of it saturated, and some of was now completely missing. Innova scoped the cladding and sheathing replacement and oversaw the reconstruction of these units.

academyInnova's investigation of soil gas odors in this newly renovated 60-unit apartment building revealed that the cause was due to significant building depressurization. Innova quantified the depressurizing effects of the buildings stack pressure, furnace flues, and its mechanical ventilation and ducting arrangements, and prescribed an elegant low-tech pressure-balancing solution.

Philadelphia, PA

academyThis 78-unit newly constructed townhouse development experienced trouble with persistent foundation water infiltration. Innova's investigations identified capillary suction of ground water at the footing as the cause. Our prescribed fix has left the basements dry and free of excess humidity.
