3. INTRODUCTION

4. • Previously, much ado has been made
about the use of alternative building
materials, low cost housing
technologies,
energy efficient construction,
alternative forms of energy etc, in the
Tropics.Yet much is left to be desired
regarding its implementation, especially
on a large scale.

5. • The realities of climate change and global
warming is now hitting home.
• Several communities are under the threat of
flooding, incessant rains, loss of farmlands and
houses, persistent warming up of the cities, etc.
• Vulnerable communities in Nigeria lack the
capacity for mitigation, leaving adaptation as
the prime option for survival in this present
times.

6. OBJECTIVES

7.  The introduction of dry wall
technology in construction will
solutions to the earlier mentioned
environmental issues,
Serve as a drive towards adaptation
Nigeria as it not only is cost effective,
but is also environmentally
and flexible.

8. OBJECTIVES CONT.
The proposal will serve as a guide for
relevant stakeholders and the
Government at large to adopt
environmentally responsive, cost
effective approaches in the provision
of public facilities in the face of
climate uncertainties

9. Advantages Of The Drywall
System
• Internal comfort- because of the insulation infill, it
reduces heat penetration and works like refrigerator,
thereby keeping internal spaces cooler.
• Reduces energy usage- because it is tropicalized, cooler
interiors, this reduces the need for air-conditioning.
• Flexibility- can be taken apart, moved to
another location for re-use.

10. Environmental Design opportunities
• Faster system of construction which will be
useful for mass production of facilities by the
Government.
• The foundations can be supported on
stanchions and this works well for flood prone
areas, as it will be based on stilts.
• The system can incorporate solar roof panels
into its framework as the wall system becomes
the roof as well. This enables electricity to be
produced locally via cells for computers, and
interactive boards.

11.  The classroom stratified according to the
existing typologies; bungalows, 1 story and
3storey buildings
 The panels comes in standard sizes of
2400mm x 1200mm , with thickness varying
from 25mm to150mm.
 Each panel has channels for electrical
wiring so all wires re hidden within the
framework.
METHODOLOGY

12. Typical floor plan of classroom block
Variant 1

13. Sandwich panels with polyurethane foam infill

14. MTD CONT.
 Typical bungalow has its level at lest
150mm-450mm above ground level.
 For the first variant the subsequent classes,
after the first, are 1m above ground level so
as to transfer the first classroom to the
upper floor s shown in the 3Ds.
