Building Standards to Minimize Water Use


The University recognizes that fresh water, electricity, and fuel are resources that need to be conserved. The University undertakes programs to reduce water consumption through natural rainwater storage systems, suitable and less water-dependent plants, and water recycling programs. The University promotes energy-saving guidelines, use of the most energy-efficient lights and equipment available, as well as the use of renewable energy sources such as solar power and other innovative means. The University focuses on emission reduction and energy efficiency in the transport sector, laboratories, kitchens and power generators.

Structures

Procurement and Purchasing. New buildings/structures should incorporate Green Tropical Built Environment Principles:

  • Rainwater harvesting for dual-pipe systems or pico-hydroelectric systems

  • Roof orientation, roof design, and structural load to accommodate photovoltaic systems

  • Double envelope systems for improved insulation

  • Better window design for improved natural lighting and ventilation

  • Efficient control and design of lighting, incl. switches/bulb placement

  • Use of LED in external/ grounds lighting

  • Aerators for water taps

  • Septic tank effluent to have or be connected to sustainable wastewater treatment systems, such as the Integrated Sustainable Irrigation Systems (ISIS) and Decentralized Wastewater Treatment System (DEWATS)

  • Innovative, clean, and/or renewable technology to improve the efficiency of energy, water, and material use


Old buildings should be retrofitted according to these principles, when possible.


Usage and Maintenance. Spaces are properly utilized based on needs, functions (interrelationship), orientation, ventilation, acoustics, mobility, safety and security, and cost implications.


Waste Disposal. Waste materials should be disposed of after considering reuse, reduction, and recycling of materials, including those from demolished structures. The health and safety of stakeholders should be considered in waste management schemes. Different units are responsible for the disposal of their respectively generated waste:

  • Disposal of waste generated in the area of another unit

  • Regular disposal of hazardous waste c/o the Central Facilities and Management Office (CFMO)

  • Construction waste (c/o contractors, upon approval of CFMO)

  • Recycling of usable fixtures and furniture through different offices and units

Water

Procurement and Purchasing. Water use is properly monitored through sub-meters and regular data collection and feedback to units. Water supply is complimented by treated wastewater and harvested rainwater for other purposes, such as irrigation and flushing. There should be systems for rainwater harvesting, stormwater management, wastewater treatment, dual flush systems for

toilets, and accessible potable water


Usage and Maintenance. Water can be optimally used and reused when information, education, and communication (IEC) programs for stakeholders, administrative support, direction from the leadership, and inter-unit communication are considered.


Waste Disposal. Rainwater is allowed to percolate to the water table instead of being channeled directly to the sewage system:

  • Design of grounds and landscape for maximum surface absorption

  • Use of permeable pavers


Wastewater is first treated and possibly reused before release into the public sewage systems:

  • Use of treated wastewater for irrigation

  • Use of harvested rainwater for flushing or irrigation
