SrAFP REPORT
201 BOrth -E" Street Bui14fn. RodificatiGDa
The purpose of this request is to identif) specific problem areas and
recolllllend remedial corrective actions within the 201 Borth "I" Street
Office Building. The attached report, dated October 29, 1991, quantifies
in detail the above referenced .concerns. Following is a brief s_ry of
the analysis and recommendations.
I. -&'I'IIG. VEln'n.A'I'TOIl AIm AIR COIlnITIOIlIIG (HVACl RODIFrCA'I'IOIS
Previous and current HVAC tenant improvements have not been designed
or installed in accordance with consideration of intended
engineerinc parBlleters or tenant occupancy. The existing conditions
are therefore wholly inadequate. Staff proposes the installation of
aodifications to the second and third floor HVAC distribution and
control networks (for full details of the analysis and
recolllllendations, see paaes 10, 11 and 12 of Chapter IV of the
attached report). The proposed improvements would provide
economical and energy efficient environmental control of the office
space. The estimated cost of these proposed t.provements is $59,000.
II.
LIOlJID _limn: AIIl'LIl"ICA'UOIl (LPAl RITIOl"I'I'
Based upon staff's review of the monthly electrical costs to operate
the bui1diD& (approximately $10,000 per month), staff secured the
assistance of a mechanical engineering firm to lnvestiaate avenues
of creatiD& efficiencies in the building's mechanical system. It
has been determined that the best and most cost effective
modification is the installation of LPA Retrofit equipment (for full
details cODcerning this and the energy savings pro formas, see paaes
14 throuah 18, Chapter V, of the attached report). The estimated
cost of these proposed improvements is $16,500. Based upon the
financial analysis of this installation, the pay-back period will be
11.4 months, with a future annual savings of approxiute1y $17,000
per year.
III. BIG l"IVl!: TI!IIAII'I' RODIl"ICA'I'rOlS
Based on review of the lease obliaations for the Bia 5 tenant space,
staff recommends the installation of modifications to the Bia 5
mechanical aystems. These improvements would consist of the
installation of LPA equipment, which would increase our savings

and decreaae our equipment maintenance coats. In addition, staff
proposes the installation of electric monitorina meters which
would allow the Aaency aa landlord to backcharae the tenant their
actual electric consumption. The eatimated coat of the propoaed
improvements 18 approximately $12,900, with an anticipated payback
period of approximately thirteen (13) months.
