potential, the design team had to take a separate solar reading for each of the units. Other
challenges included tree shading, structural
limitations of the existing buildings, existing
electrical service equipment and interconnection with Pacific Gas & Electric (PG&E, pge.

In the end, the team decided to connect
each building’s PV system to the existing electrical service equipment via a line-side tap. This
avoided the expense not only of installing new
electrical service equipment, but also of associated upgrades to the entire utility infrastructure. Approval of this approach was closely
vetted, with city building officials and PG&E
as active participants.
The renovation, budgeted at approximately
$50 million including a new multicultural family resource center and upgraded computer
center, was phased over a 25-month period,
during which the complex remained occupied.
The contractor received three vacant buildings
to renovate at a time, staggered one month
apart, giving workers approximately 12 weeks
to renovate each building inside and out and
install the PV system.
EAH Housing and its partners worked
closely with the Crescent Park Resident Council to relocate residents within the complex
efficiently and comfortably. Buildings were
vacated on a scheduled and orderly basis with
minimal disruption to residents’ lives.
The financing of the project included a sale
by its previous owner to an EAH Housing-con-trolled limited partnership which involved —

All of the bonds, both the taxable and tax-exempt, were issued by the city of Richmond.
Pre-development financing from several sources was repaid at the time of the close of sale to
the new owner.
“EAH Housing accomplished this without
any new subsidy loans from any source,” said
development, who structured the transaction.
The PV contractor provided a fixed cost
for the modules and maintained a delivery
schedule spanning two years. It also required
flexibility on the owner’s part to work through
challenges associated with the general undersupply of solar panels in the marketplace, in
order to ensure timely delivery of the panels
maintained a good relationship with general
contractor West Coast Contractors (west-
& Power ( sunlightandpower.com), allowing it
to keep the schedule flexible. The PV portion of
the renovation is fully paid for via —
• More than $1.7 million in California
Public Utility Commission rebates, under
• The reduction in owner-paid electricity costs for this master-metered complex by
almost $154,000 per year. This budget reduction permitted almost $3 million more in bond-financed permanent debt to be supported.
Although there are limitations to the benefit of the renewable energy tax credits in low-income housing tax credit and tax-exempt private bond financing, the true value is largely
entirety of tax credit at the time the PV system
is placed in service. ST
