<strong>CUSTOM</strong> <strong>RETROFIT</strong> <strong>GRANT</strong><br />

Hands-Down Decision: Retrofitting a Bellevue Office Building<br />

With Condensing Boilers and a PSE Grant<br />

“<br />

Once PSE told us it<br />

could pay 70% of the<br />

cost of a high-efficiency,<br />

natural gas-fired heating<br />

system, it was an easy<br />

business decision.<br />

”<br />

THE PROJECT<br />

Outdated electric resistance space heating at a nine-floor, 96,000-sq-ft<br />

Bellevue office building was costing Legacy Partners Commercial big<br />

money. Upgrading to a high-efficiency heating system with natural gasfired<br />

condensing boilers would eliminate over 516,000 kWh a year from<br />

the building’s utility bill, and a <strong>Puget</strong> <strong>Sound</strong> <strong>Energy</strong> Custom Grant would<br />

cover 70% of the retrofit. Throw in a parking garage lighting upgrade that<br />

would cut another 45,000 kWh a year, with PSE paying nearly 40% of<br />

the cost, and you have a deal.<br />

<strong>CUSTOM</strong> <strong>GRANT</strong> - <strong>RETROFIT</strong><br />

Hands-Down Decision: Retrofitting a Bellevue Office Building<br />

With Condensing Boilers and a PSE Grant<br />

THE PROJECT<br />

Sometimes even a major retrofit can be a quick hands-down decision. It doesn’t<br />

get any easier than Legacy Partners Commercial, Inc.’s decision to exchange<br />

outdated electric resistance space heating for a high-efficiency gas hydronic<br />

system in an office building at 10655 NE 4th Street in downtown Bellevue. Built<br />

in 1972, when electricity from Northwest hydropower was memorably inexpensive,<br />

the nine-floor, 96,000-sq-ft office building was heated by a 600-kW electric<br />

resistance system.<br />

THE CHALLENGE<br />

As the price of electricity escalated, so did the building’s heating bills. Legacy<br />

Partners Commercial, a real estate investment manager, owner, and operator of<br />

a 13 million-sq-ft property portfolio, acquired the building in 2005 and began<br />

looking for more efficient ways to heat it. “We’re always thinking about saving<br />

energy—we move quickly to increase value and maximize returns,” explains Tom<br />

Jodry, senior vice president of facilities at Legacy Partners. “We looked at the<br />

building’s operating income and operating expenses, and compared it with similar<br />

properties in that immediate market.” No doubt about it, the old heating system<br />

had to go.<br />

THE SOLUTION<br />

Jodry also had no doubt that PSE’s Custom Grant Program was the way to go:<br />

PSE had approached Legacy Partners about energy-saving opportunities, and<br />

sent an engineer for a building walk-through. PSE’s engineer vividly recalled<br />

the hot deck of the 600-kW electric heating system, its 8-ft-tall walls lined with<br />

electric coils: “It was like being inside a giant toaster.” PSE recommended a hotwater<br />

hydronic heating system featuring high-efficiency condensing boilers fired<br />

by inexpensive natural gas. The proposed retrofit would save Legacy Partners<br />

more than $13,000 a year by using 19,700 therms of natural gas per year—at a<br />

cost of only $18,900—instead of 516,000 kWh of electricity a year, costing some<br />

$32,200. The clincher: PSE offered to underwrite most of the retrofit. “Once PSE<br />

told us it could pay 70% of the cost to retrofit, it was an easy business decision,”<br />

says Jodry. “That was a very appealing percentage.”<br />

PSE also recommended replacing the inefficient high-pressure sodium lighting<br />

fixtures—all 84 of them—in the building’s three-floor, 131,000-sq-ft parking garage<br />

with high-efficiency T-8 fluorescent fixtures. Garage lighting operates 24/7, and<br />

PSE calculated that replacements could easily halve the electricity used to light<br />

the 1,000-parking-space garage, saving over 45,000 kWh, or close to $4,000,<br />

a year. PSE chipped in with a grant that would cover nearly 40% of the cost of<br />

lighting replacement.<br />

THE START OF SOMETHING<br />

Knowing a good deal when he saw it, Jodry gave the go-ahead for both retrofits.<br />

Soon after, local contractor McKinstry demolished the building’s eight 75-kW<br />

resistance heaters and replaced them with two 1 million-Btu/hr condensing<br />

boilers and three hot-water coils. The new boilers operate most of the time at<br />

or near peak combustion efficiency of 91.5%. Lighting contractor Light Doctor,<br />

Inc. finished the job by installing the new lighting fixtures in the parking garage.<br />

With the help of the PSE grants, the new space heating system and the lighting<br />

upgrades will pay for themselves in about four years. All business decisions should<br />

be so easy.<br />

PROJECT PARTNER<br />

Legacy Partners’ upgrade<br />

of the office building’s<br />

heating system was made<br />

as painless as possible by<br />

contractor McKinstry’s turnkey<br />

approach. McKinstry<br />

contracted for start-tofinish<br />

services, including<br />

demolition of the old<br />

heating system, installation<br />

of the new gas-fired heating<br />

system, system startup,<br />

and post-installation<br />

commissioning.
