Importance Of Building Design In The Philippines

INTRODUCTION

BACKGROUND OF THE STUDY

In response to the demand for residential spaces in the Philippines, condominium buildings are established in different parts of the country. Operating with modern facilities and amenities, and being a high-rise structure with large number of occupants, this type of building demands higher cost for its management and maintenance as compared to other private-owned houses and apartments.

With these problems on high maintenance costs and operating expenses, sustainable building design strategies have been developed as an effective approach to this issue. A structure is deemed to be sustainable if it maximizes the use of natural resources such as wind, water and sunlight to minimize expenditures and consumption

To help the environment, the design of the building includes proper waste segregation as a waste reduction strategy and indoor gardens to help reduce the carbon dioxide emission, thus making the building environment-friendly.

The project can also help the occupants of the building. Indoor gardens add up to the conducive atmosphere of the building which can be beneficial to the health of the residents. With the use of natural lighting, ventilation, and rainwater, water and electrical energy will be conserved, thus reducing expenses on electrical and water bills of the
