consumption. Then the most suitable solutions and materials will be chosen for optimum

energy efficiency. The heat losses will be measured again, and the option of

supplementing these losses along with other energy needs (electricity, ventilation) is

examined by renewable energy potential. The energy source that is most available in site

should be chosen.

So the retrofitting of the building in Singapore is a challenging project which requires

consideration of efficient and sustainable technologies in order to minimise energy use

and maximize comfort levels in the building.

1.2 Building Description

The building is located in Singapore. It is a three storey building which has a rectangular

shape with dimensions 10.4m height, 18.6m width and 54.4m length. The site plan of the

building shows that it is surrounded by other buildings from the north, south and east

sides with the first two being much closer (Figure 1). The ground floor is used as an

exhibition centre, the first floor as a library and the second floor for offices. The basic

spatial requirements for this building include reception areas, toilets and circulation

spaces. The office floor includes an office space, a small kitchen area and a photocopy/printing room. The library includes reading rooms, book storage spaces and café. The population density values according to CIBSE guide are 10m2/person for offices and libraries, and 3m2/person for exhibition halls. These values are not expected to be

constant for the exhibition centre and library. There are also several aspects affecting the

thermal performance of this building, including glazing, wall and roof fabric, and

ventilation which can be modified. Population also affects the thermal performance but

obviously cannot be changed.
