                                ENVIRONMENT

Air Quality in downtown
 High traffic volume and traffic congestion

 Lack of emission laws

 Unsuitable sitting of industrial zones

integration, and the ‘Compact City’ & ‘TOD’ planning policies. He is also interested
in sustainable mobility and especially in bicycle & pedestrian planning and design

FUTURE
FUTURE TRANSPORTATION
                   USING New diesel-electric
            TRAIN INSTEAD OF AN OLD KTM RAILWAY
The Train-Trams will be used in both regional traffic as well as in inner-city traffic.
Speeds of up to 100 km/h can be reached in regional traffic and almost 70 km/h in
inner-city traffic.
FUTURE TRANSPORTATION
     USING THE PERSONAL POD CAR INSTEAD OF CURRENT
                    PRIVATE VEHICLE
Low capital and operational costs   Flexible routing

24-hour availability                On-demand service with no transfers

Zero on-site emissions              Extremely low overall energy use
FUTURE TRANSPORTATION
USING THE electrified TAXI INSTEAD OF CURRENT TAXI
FUTURE TRANSPORTATION
     DESINING NEW AND MODERN AIRPORT IN TERMS OF
       SUSTAINABILITY OF KAJANG (COOLING PLAN)
When you build a state-of-the-art airport in one of the hottest places on the globe, a
cooling plant is an indispensable part of the equation. District cooling is a far more
“
sustainable way to provide air-conditioning compared with traditional, individual
cooling plants, because energy and resources are utilized more efficiently
SUSTAINABLE TOURISM
Enhance existing nature potentials to attract tourism through the world and using
private sector investment to create hotels and other requirement facilities in order to
relief of tourists.
FUTURE ENERGY
                               SOLAR ENERGY
This free energy from sun can be easily converted into electrical energy to reduce
energy costs and provide electricity in remote areas where infrastructure is limited
FUTURE ENERGY
                                SOLAR ENERGY
Production of own energy from the house by installing solar panels could reduce the
electric power demand.
FUTURE ENERGY
                           BIOMASS ENERGY
Biomass energy is energy from plants and plant-derived materials—and has been
in use since people began burning wood to cook food and keep warm. Biomass
sources include food crops, grassy and woody plants, residues from agriculture or
forestry, organic components of municipal and industrial wastes and animal waste
such as cow manure and chicken litter. Fundamentally, biomass is stored solar
energy that man can convert to electricity or fuel .
FUTURE ENERGY
                                BIOMASS ENERGY
Correctly managed, biomass is a sustainable fuel that can both offer a significant
reduction in net carbon emissions compared with fossil fuels.
FUTURE WASTE WATER SYSTEM
This figure outlines a sustainable wastewater system. Rainwater and water from a
catchment area are stored in a lake for use by residential and commercial users. Roof
water is also used by residential users. Grey water from baths, showers and other
domestic use is recycled and dispersed into the ecosystem. Stormwater from commercial
users is piped to silt ponds for evaporation and for re-use. Wastewater from homes and
commercial users is treated in a small-scale plant; solids are composted and treated
water disposed of into silt ponds. When the water makes it way from the silt ponds to the
sea, it is clean.
