Towards Green BuildingCase study: Fine Arts Building( at An Najah national University)

Prepared by:Ayah HassanGhadeer OtearSaja Sweidan

Supervisor:Dr. Mutasem BabaThe Project Idea:

Modify Certain aspects to make the Building more environmentally friendly (green).

Chapter OneArchitectural and Environmental design systemArchitectural Design:A (48x41) m building consist of a basement with an area of (1003.5 m2),(1668.9m2) for the ground floor, (139.89m2) for the roof and (1571m2) for the rest floors.The Faculty was designed in the latest specifications and standards, and provide 19 classroom and 28 studios designed specifically to meet the purpose for which it was designed for.Architectural plan:

Element for green design:Thermal.Acoustic.Handicap.Safety.Lighting.Water management.Also, Structural design.

1-How to increase Thermal efficiency of a building::Thermal problem solved by:Insulation.Shading.Skylight.

Insulation:

Type of Insulation used: Polyurethane foam and panel:

For Example, Outside Wall:

Before insulation.

After insulation.U1= 1.64 W/m.c

U2=0.66 W/m.c

U2/U1=40.2%STC2=60STC1= 52

North Elevation

South Elevation

West Elevation

East ElevationSecond Elevation: South Elevation.

Drawing of shutter.Dimension of window =(1.25*1.25)m.

Assume length of shutter = 10cm

Tan()=height of shutter/ length of shutter

h= tna()*L

h = 22cm.

Second Elevation: North Elevation.

Library.Solution :In this project we use the double glazing.

Benefits of this Method :

**Reduce Energy Transfer.

**Day lightingThird Elevation: West Elevation.

Solution One: Use shutter.

Another Solution :In this project We Use Vegetative Shading

Kind of trees can be use:

Walnut treeEucalyptus tree

Possible place for Trees.

Fourth Elevation: East Elevation.

Skylight:

Black sheetAcoustic Tiles In Summer:

In Winter:

2-Noise Reduction:Noise Reduction from outside:Using polyurethane in outside wall.

For Noise room in First floor:Using egg craft insulation in walls, and acoustical tiles. in structural Borne (Drums room) use PVC or rubber Tiles.

3- Safety:

Emergency Exit in Ground Floor:

The door inside the building.The new door can use in the building.

3- Safety:Adding another Emergency Exit in Ground Floor:

4-Handicap ramps design:

First Ramps In The Colleges.

The Solution Of This Problem.

Slope 1:10Second Ramps In The Colleges.

Third Ramps In The Colleges.

The main entranceto theCollegeThe Solution Of This Problem.

Another Solution For Handicap Ramps.

Architectural and Environmental Modification:Adding Handicaps Ramp.Adding another Emergency Exit.Adding Shutters for the north and south Windows.Adding a Shutters(Solar chimney)for the void.Using Polyurethane and egg craft.Using Rubber Tiles in music room.Using acoustical Tiles.

Chapter TwoStructural DesignStructural Design Project description :

South elevationNorth elevationWest elevationEast elevationThe 41*48 building is considered as one block

Project design dataThe American Concrete Institute code ACI 318-05 .The seismic design according to UBC-97.Then the analysis and design are done using 3D model using SAP2000 program.Material used:B350 concrete is usedf'c=300Kg/cm Unit weights of materials: Reinforced concrete = 2500 kg/m3. Hollow block = 1000 kg/m3.Eaton blocks =470 kg/m3.The yield strength of steel for flexure equal fy = 4200 kg/cm2 and for shear reinforcement equal fys = 4200 kg/cm2. bearing capacity of soil = 4 Kg/cm2.Soil density 19.2 KN/m3

Structural system:In this block we use two way ribbed slab with 40 cm depth.

LL=0.5 ton/m.

SID=.35t/m

Wu= 1.85ton/m.

Main beams is assumes to be 70*60cm (drop beam)

Secondary beams (above shear walls) assumes to be 40*30Column dimension calculation

Model design on sapEquivalent solid slab thickness = .3089 mSet modifiers factors

Roof steel truss loads were interred on the shear walls carrying the truss D.L= .8 KN/m2 S.L =1.5 KN/m2L.L = .5 KN/m2 (booth L.L and S.L is assumed to be live on the sap )Since the angle of the truss
