THE ATRIUM

Uncomfortable Tenants - Uneasy Owners

The Atrium: Before

Frustrated, uncomfortable

tenants refused to renew

their leases, and prospective

tenants weren‘t interested in

signing up.

The building‘s occupants

experienced wide daily

temperature extremes, drafts

and stuffiness. There was

excessive noise and vibra-

tion. Summer temperatures

ranged to over 80 degrees,

and winter conditions varied

between too cold and too hot.

The Monsen —Total Responsibility Solution“

Monsen‘s Facilities Planning Group identified deficiencies in the original design stem-

ming from —looped“ duct distribution. Monsen reconfigured the loop so units operated

independently, changed duct fittings that were too small and varied fan speeds to

maintain pressure without abrupt changes. Monsen applied automation intelligence to

the building with a control system that integrates heating and cooling and has the

capability of metering electricity as needed.

Cost

: $350,000, including building study, design costs, installation, parts and

recommissioning.

Cost Overruns

: None

Timeframe

: 20 weeks. To minimize tenant disruption, much of the work was

scheduled during weekend and evening hours.

The Atrium: After

Tenants are comfortable and can now control their comfort. The owner can monitor

the energy tenants consume during off-hours. The building is operating comfortably

and efficiently. Tenants threatening to leave have renewed their leases. The first

year‘s maintenance and energy savings are helping to pay for the installation.

The Atrium, in Fairfield, NJ is a three-story 100,000 Ft“ office

building. It is occupied by multiple tenants.
