 REACTION PAPER ON POST OCCUPANCY EVALUATION

Post Occupancy Evaluation (POE) is a process of analyzing how functional

and comfortable a building is after users have been occupying it for some
time. Most firms wait at least six months after construction before
performing these evaluations, but some wait a year or longer to gather
more data.

This study of applying Post Occupancy Evaluation (POE) to the

performance of PABLO R. HALILI COMMERCIAL BUILDING owned by Pablo
and Annie Marie Halili, to measure or assess if the structure achieved its real
purpose as a commercial building. In this manner the building will evaluate
from the facilities, utilities, and the users.

Base on the background of the study, a building was built for shelter; that is
about the basic purpose of these structures. They are architecturally
designed and erected to provide shelter to people, properties, and other
material; protect them from the elements; provide internal spaces adapted
and suitable for various forms of human activity and provide the distribution
system for critical utilities such as power, heating (or otherwise cooling), gas,
and water in order to enable users to conduct their businesses and affairs
with convenience. Most of the structures today sis not meet what is its
purpose. As an owner of this building, they should know how their building
perform and that were the architects and builders enter because they
have the knowledge on how to address the problem.

And that’s the POE coming in, it is a method to assess to provide a

feedback in giving the existing building a sustainability and to still adapt the
existing properties to a newly environment.
The study follows the path for logical and temporal constraints. In the
purpose of approaching the building through evaluating in the city of
Baguio in the Cordillera Administrative Region (CAR).

In the statement of the problem, the researcher addresses the general

problem stated, thus “successful is the Pablo R. Halili Building in meeting the
expectations of its builders and users along selected 8 key building
performance areas?” In the assessment, it is listed of unpacking bunches of
problem questions. The researcher stated his hypotheses regarding to every
problem.

As for the conceptual framework of the researcher, the study has two
divided variables. The first variable contains the different types of users of
the building and the second is the 8 key performance areas of POE in
application for the building.

The researcher listed 6 reasons to signify its research study. And the
researcher introduced the five integral elements of BPE in the scope and
delimitation of the study, that isn’t utilized in providing sustainability to the
existing building.

In the study, the researcher listed 16 terminologies in order to understand

what is being discussed and to fully the study itself. It is very convenient to
apply a framework in order to clearly understand what is the purpose of
POE and its importance. The researcher also discussed the levels of POE in
its study.

Methods and procedures, here was the overview of discussion of the

applications applied in the study. The strategies used by researcher to this
study are the combination of qualitative are made of interviews and the
quantitative will be utilized by pre-coded numerical form. The researcher’s
study maintains that the SED is particularly adapted to POE.
Under Site discussion, the researcher’s study is focused on Post Occupancy
Evaluation of Pablo R. Halili Building, therefore the function as the research
is the building itself.

Further discussion, the owners intend to reside at the building penthouse

while the floor immediately below it functions as a dormitory for students
mainly SLU students. A trading company, the Royale Business Club, leases
commercial space at the third floor while the second floor is leased by a
computer shop and an education/learning facility. The ground floor is
leased by a pharmaceutical company and a restaurant; it also holds the
building administration office. The first basement of the building is a parking
lot for the tenants and owners while the second basement is leased by
another dormitory for students. There is another learning center at the third
basement while a Korean language center and an air gun shop rent space
at the fourth basement whose facade opens out to T. Alonzo.

In this study the researcher needs the population samples from the owner’s
representative to the users. In order to execute this analysis, the researcher
introduce the Cochran Formula. Below is the Cochran formula equation

Where: n0= sample size

Z = the z-value in a z table for a confidence level of 95%

(i.e., 1.96)

e = desired level of precision, 5 % or 0.05 (i.e., the

margin of error)

p = estimated proportion of the population with the attribute in question

(0.50 for 50-50)

q = 1 – p. (1-0.50). q = 0.50
Where n0 is the sample size, z is the confidence level, p is the
estimated proportion of an attribute that is present in the population=1-p,
e = desired level of precision.

And the second equation is a Correction Formula.

n = _____No____

1+(No – 1)

The researcher has the total of 378 respondents to distribute and compute.

In its data gathering and methodology discussion, the data consist of 2

separated stages as per the SED. It says that the “first stage” commence
with a total enumeration of the building owners and his representative. This
was followed by the identification of the sample groups and the
administration of the questionnaire to the selected respondents. And been
discussed the different subsections. The “second stage” of the data-
gathering phase consisted of intensive interviews to several key informants
were selected from each users of the building groups including the owner’s
representative, the boarders/transient residents, educational service
providers, business office lessees, retail trade lessees, and food services
lessees, and customers of the lessees. The interview was meant to
supplement with qualitative data the results of the quantitative survey on
building performance along the eight key performance areas.

In the treatment and analysis of data discusses the statistical procedures for
the study made use of the statistical package for the social sciences version
25. The researcher emphasized the formula for the manual computations
of the statistics are provided in this section. And to answer the first problem
of the study, means and standard deviations were used.
 this is the formula that is been used.

Where: μ= weighted mean

f = frequency response

x = individual response

To arrive at a definite conclusion for the computed weighted mean and its
corresponding interpretation, the researcher used the following
quantitative scale value.

Where:

SSB = sum of squares within columns

∑Xc = sum of the individual values per column

n = size of the sample

SSW = TSS – SSB

Where:

SSW = sum of squares within columns

The researcher really thought of it by using many different formulas to

obtained the validity of the study as for the discussion in the validity of
questionnaires, from validity of the content to criterion – related. The
reliability of the questionnaires also been discussed.

In the results and discussions presents the analysis and interprets of the
gathered data from the survey and been tabulated. Post Occupancy
Evaluation provides important feedback for providing sustainability to
existing building. The study shall confine itself to the “eight key performance
areas” specifically the provision of utility services, affordability, comfort
health and well-being, architectural quality, lighting and ventilation, safety
and security, service maintenance, and management.

Under occupancy data, the post-occupancy evaluation survey elicited

responses from three types of building users.

As for the affordability, based on the study, the building was rated GOOD
in terms of the overall satisfaction of the respondents on the building’s
affordability. specifically, respondents rated the building merely as GOOD.

In the architectural quality, along the key performance area of

architectural quality, respondents evaluated the building as FAIR. long this
dimension, the building was evaluated as GOOD in its exterior and façade,
stairwell and staircase.

In the lighting and ventilation, along the key performance area of lighting
and ventilation, respondents evaluated the building as FAIR. long this
dimension, the building was evaluated as GOOD in its room and facilities
lighting, building frontage lighting, building front and rear entrances lighting,
d in windows being adequate to dispel toxic fumes from vehicles. However,
some of the facility and utility of the building is evaluated as FAIR.

The security and safety system of the building is also discussed in this study,
the respondents evaluated the key performance area of the building as
FAIR. In terms of dimension, the evaluation is GOOD.

The services and maintenance are also evaluated the key performance
area of service and maintenance, respondents evaluated the building as
FAIR.

The overall summary of the evaluation key areas in terms of satisfaction

levels was evaluated as FAIR from the utilities, architectural quality, lighting
and ventilation, safety and security, service and maintenance and lastly
the administration and management. But the building itself was evaluated
as GOOD and FAIR as a whole.

In the LEVELS OF SATISFACTION BY TYPE OF BUILDING USER, this section

discusses the findings of the study in terms of the levels of satisfaction of
various types of building users, i.e., the lessees, boarders, and customers.
These findings on levels of satisfaction shall be discussed by key
performance area.

Now, the researcher named 8 recommendation in its discussion for the

Pablo R. Halili Building. It is very effective that the researcher gives his
recommendation in every problem that is been discussed in the early
chapter of the study.

These 8 recommendations are as follows:

First, in building utilities, improvements must be made along the specific

items of providing operational elevator, backup power through a
generator set, improving internet services, and lighted basement parking
facilities.

Second, in terms of affordability, the study recommends attempts to

making more reasonable the occupancy rental rate, add-on rates, room
rates, and rates for other services than those included in the scale of items.

Third, along the key performance area of comfort, health, and well-being
the study recommends improvements in janitorial services, the provision of
no smoking signage, common toilets and hand washing facilities, ensuring
a rat and rodent-free environment, and in the provision of PWD/ child/
pregnant women/ senior citizen friendly facilities.

Fourth, in terms of architectural quality, the study recommends

improvements in interior design, parking facility design, and drastic
improvements in landscaping. Landscaping is rated poor in the findings
which administration must address this problem, landscaping maintenance.

Fifth, along the area of lighting and ventilation, improvements are

recommended in corridor lighting, stair well lighting, parking area lighting,
back-up/emergency lighting, and in the provision of adequate skylights
and windows for air circulation and natural lighting and fresh air enabling
to reduce utility expenses.

Sixth, in the area of security and safety, improvements must be done to

increase the feeling of safety through enhanced security guard visibility, the
strategic installation of CCTV cameras, accessible and clear fire exits, visible
and clear signage and plans for evacuation in cases of emergency, fire
extinguishers and other fire-fighting equipment, sprinkler systems, smoke
detectors, and the provision of non-skid and durable floor tiles of rooms,
corridors, washrooms and restrooms’ floors.

Seventh, regarding services and maintenance, improvements in all the

items identified therein. Improvements must be done to accessibility and
approachable janitors and maintenance personnel, strategically located
maintenance room and janitorial office, warehouse room, prompt and
immediate response to maintenance requests, assistance in documents
processing, special assistance in interior design and layout, readily
available support and assistance, and complete set of service tools and
equipment.

Finally, in terms of general administration and management,

recommendations are forwarded for improvements in certain items in
general administration and management particularly in the clear and
complete posting of the building directory, a well-known organizational
structure and officers, and the improvement of the services and conduct
of personnel including the building administrators, the information and front
desk staff, safety and security officer, electrical engineer, security guards,
janitors and housekeepers, and parking attendants.

As for the conclusion, the researcher well discussed the findings of the study,
that the target results was achieved.
