Kitchen Plan and Grand Design
Modern-day kitchen furniture layout is known to be modular, especially designed to optimize functionality and the use of space.
These kitchens use various modules (units) of cabinets that are crafted out of diverse materials and hold kitchen accessories inside. The basic structure of a modular kitchen is extremely practical. READ MORE
Water Desalination to address Water Scarcity in Karachi
With a population of 23 million, Karachi is the third most populous city in the world. The metropolis faces acute water scarcity. According to Karachi Water and Sewerage Board, the total water demand of the city is 1,000 million gallons per day whereas the city is receiving only 400 million gallons daily. This shortfall is attributed to non-availability of sufficient water in the Hub Dam due to lack of enough rainfall. The board also mentioned that 15 percent of the shortage comes from water theft and the menace of unauthorized connections.
Karachi, situated on the coast of Arabian Sea, is blessed with sea water supply. Water desalination could be one of the potential solution for addressing the water scarcity in Karachi. Desalination is the process by which seawater is rendered into fresh water. The seawater is heated to the point of evaporation, and the resulting vapours are then condensed into fresh water.One such plant exists in the Defence Housing Authority (DHA) one of the largest muncipal authorities in Asia. The plant called DHA Cogen Limited (DCL) was built in 2003 as a joint venture between DHA and Sacoden Investments of Singapore. The plant uses Alfa Laval technology to produce portable drinking water. DCL is a cogeneration plant i.e. its produces electric power in conjunction with the fresh water. At present it produces 3 million gallons of water per day and 94 MW of electrical power supplying to more than 100,000 households and businesses in DHA. DCL could be taken as a model or case study for more such plants in Karachi to meet the city’s water scarcity.
Clifton and Defence - Livable City Karachi
Landscape conducted a preliminary design study for Clifton and Defence areas to make these areas Karachi’s revitalized City Spaces. The study recommended enhanced street design through landscaping solutions with emphasis on pedestrian right. Design solutions included introduction of shared open spaces in public areas such as Abdullah Shah Ghazi Mausoleum and McDonalds at Seaview with plantations of local species, public seating and unique facade designs. Scrambled pedestrian crossing is recommended for the Submarine Circus to allow pedestrian crossing along with traffic management. A sustainable design solution is proposed for the site which includes incorporating waste recycling system, solar street lighting and improved signage that promotes civic sense and environment. In order to implement a sustainable urban living at the site area a Green school is also recommended to promote world-class research on sustainable Karachi.
Integrated Coastal Management for Karachi Beaches
Karachi is a coastal city located on the Arabian Sea coastline. There are many beautiful seaside near city like Seaview, Manora Island, Sandspit Beach, Hawkes Bay Beach, Paradise Point and French Beach. These beaches hold substantial environmental and economic significance being the home for exotic fauna (such as Dalmatian Pelican, Turtles, etc) to being the sea-route for commercial activities in the country. At this point in time the effective coastal management lacks at the beaches which are vulnerable to pollution, lack of proper care due to growing human traffic at the beaches and security for visitors.
In order to address these challenges at the beaches, Landscape proposes an integrated coastal Management study for the Seaview, Hawkes Bay and Manora Island beaches. According the Campnet, 1991 Integrated coastal management (ICM) is a dynamic process in which a coordinated strategy is developed and implemented for the allocation of environmental, socio-cultural and institutional resources to achieve the conservation and sustainable multiple use of the coastal zone.
The purpose of ICM is to increase the efficiency and effectiveness of coastal governance in terms of the coast’s ability to achieve the sustainable use of coastal resources and of the services generated by the ecosystems in the coastal areas.
Green Building Standards in Pakistan
Built environment is a major source of CO2 (Greenhouse gas) emissions, energy and water consumption, conventional air and water pollution and solid waste stream. Landscape believes that a building that approaches sustainability and green materials from its design phase has a very strong potential to perform in an environmentally friendly manner. Based on this, Landscape believes including “green” standards during the design phase is a proactive way to reach great performances.
There are four main benefits of green buildings:
- First, green buildings help in reducing the overall carbon emissions from the building. Use of sustainable material consumption further ensures sustainable design and hence reducing the overall footprint of the building.
- Second, they allow quantifying potential savings from green building initiatives such as water, electricity consumption, etc.
- Third, green building incorporates environmental design which helps in encouraging implementation of new technology and innovative measures.
- Fourth, green building measures enhance a building’s value and aesthetics- environmental design helps to increase the land value and best practice measures enhance the life span of the building.
At present there are about 18 to 20 buildings in Pakistan which are LEED Certified and registered with the US Green Building Council. These include British Council Library in Lahore, NCC Karachi, Mega Corporate Office, Karachi, Karachi Citiplan, World Bank Country office, Islamabad, etc.
Pakistan Green Building Council (PGBC) is responsible for developing design guidelines for green buildings in Pakistan. The environmental team at Landscape looks forward to contributing to the PGBC’s local standard development for green buildings in Pakistan.
