B. ZONING, HEIGHT and BUILDING FOOTPRINT OF BUILDINGS

1. Designated Zones

The identified campus zones: Institutional, Agricultural, Agro-industrial, Agri Eco-Tourism, Commercial,
Recreational, and Residential are designated as guide in the future development plans for the campus.
This is also to maximize future opportunities to concentrate on instructional activities within the
academic / institutional core up to the greatest extent possible of locating buildings of new programs
and other spaces supporting more Instructional activities.

2. Restrictions to Height of Buildings
Clear Zones

Buildings should be low-rise in development to ensure stability in the face of any earth
movement and strong wind pressure affecting the building foundation and structural
framework. The wind speed and wind gust varies with height, being slower near ground
level where the wind is slowed down by the roughness of the ground, and faster at high
altitudes where there is less interference to the wind's forward speed. This effect can be
measured at altitude intervals of 10 meters and thus taller buildings are subjected to higher
wind speeds than are low buildings.

3. Maximum Building Footprint

As per the National Building Code of the Philippines, any school or university falls under

the Institutional Zone. The total maximum buildable area (building footprint) of all buildings Restrictions to height of buildings
for the campus shall not exceed 50% of the total lot area. The more open spaces, the more
the development will be considered sustainable.

4. Roof Configuration vis a vis Wind Load Factor

Since the province of Isabela is located under Zone 1 (high wind zone) as per the New Wind
Load Provisions in the Philippine Structural Code of 2001, the roof configurations should be able to
withstand a basic wind speed of 250 kilometers per hour.

As the wind passes over or around objects such as trees, ridges, fences, buildings, cliffs and valley,
the wind becomes turbulent and causes local increases in air speed and wind pressure. The effect
of these air pressures on the edges and perimeters of these obstructions can become much more
severe than the normal wind pressure. Roof Deck

With climate change and the location of ISU, it is frequently visited by typhoons, hence, a need to Hip roof
retrofit and redesign roofs is a necessity. Hip roofs with eaves should be protected by parapet walls.
Having roof decks with the right waterproofing system are also good alternatives. These can also be
a place for rainwater harvesting equipment.
