This project studies building performance evaluation with cases of selected buildings within Federal College of Education, Akinmorin, Oyo State.
INTRODUCTION
1.1 BACKGROUND OF THE STUDY
Architects, designers and building occupants (and/or users) and other
professionals involved in building construction over the years have generated series of
controversies in the design, planning, use, and maintenance of buildings (and its
environs) and the level of satisfaction they provide. A comfortable indoor environment
is an important parameter in the productivity, happiness and satisfaction of building
occupants. As such, building on completion should perform its functions in the manner
that will ensure desirable satisfaction to its occupants, therefore, the design and
implementation of buildings should be given careful thoughts and considerations.
Regular maintenance programs conducted after the building has been occupied also
ensure that a building functions well at all times. Natasha Khalil (2000) said that by the
execution of these maintenance programs, the occupants will be able to use and utilize
the facilities as the provision of facilities supports the business operations by the building
occupants. In short, the building facilities and services must be fit for the purpose of the
users. It should however be noted that there are some instances where irrespective of the
level of maintenance executed, once a building does not fit into the environmental
fabrics at inception, it may be difficult for such a building to meet the required comfort
for utmost productivity of its occupants.
Again, emphasis on resource management, in particular energy and economic
resources, has put a new stress on the building industry in addition to the traditional
building demands of health, safety, and welfare. This abrupt emphasis of a single
building requirement has in turn triggered a series of measurable building failure For

example, a demand for air tightness has raised questions of air quality and building
inadequacies regarding human health. It is not the focus on energy conservation or other
resource management efforts that is at fault for building failures, but the lack of
transdisciplinary understanding of the impact of each building performance mandate has
on the other performance areas. It is therefore the challenge of the 1980s and 1990s to
understand the critical balance needed to simultaneously ensure the fulfilment of all
building performance mandates. The importance of understanding the total performance
of a building in a holistic sense is undeniable. In many instances, building evaluation is
a first priority as it is imperative to know the status quo of the building before one can
effectively predict future building performance (ASCE).
The concept of overall performance, Total Building Performance (TBP),
emerged in the last decades of 20
th
century, provides a tool for assessing the quality of a
building, in terms of the extent to which all the requirements of performance are satisfied
(Cortana & Goretti, 2007; Roulet, 2004). In order for buildings to achieve its purpose of
providing desirable satisfaction to its occupants, its design process, planning,
construction and management are based on statutory standards and specifications
established by governments, professionals and experts who are supposed to have
adequate knowledge of users’ needs and expectations (Eziyi Offia Ibem, Akunnaya P.
Opoko, Albert B.Adeboye, Dolapo Amole). Studies according to Kaitilla, 1993, Ukoha
and Beamish, 1997; Zeiler and Boxem, 2008; Meir (2009) et al have however shown
that sometimes these standards and specifications do not conform to the chang
