Recycled Bin Storage
Segregated recyclable waste bins are recommended for effective waste reduction, through segregation of paper, plastic and metal items helps divert waste from being disposed into landfills and ensure that the waste is being contained from the source.
Radiant Cooling
A Radiant Cooling system (also referred to as Chilled Beam system) can significantly lower the cooling load on a chiller by utilizing water instead of air as the medium of heat transfer in the HVAC system. Chilled beams consume less fan energy, require less ceiling space, and are much quieter. Such systems are expected to lower the chiller cooling load by approximately 20%. Insulated floors can regulate cooling demand.
Ceiling Lights
Indoor Lighting
Maximize on natural daylight usage – a study of 2000 California classrooms found that students in classrooms with the most daylight progressed 20% faster in math and 26% faster in reading than students in classrooms with the least amount of natural light. Moreover, a well-designed school building with ample natural lighting is estimated to reduce lighting energy use by 50% to 80%.
Windows Shades
Large windows provide a generous amount of daylight but if not controlled properly this light can produce unwanted glare and affect interior lighting quality. Measures to control glare include adding light shelves, louvers, blinds, and shades into the design of the building façade.
Lighting Controls
Lighting controls in schools help regulate energy usage. Multiple lighting control options serve a similar purpose where indoor occupants can turn off lights that are near windows during peak daylight hours. Occupant education and awareness goes a long way in preventing employees from leaving lights switched on when they are not needed. In addition, using sensor technology is a beneficial step to take for building owners to further utilize energy saving investments.
Climate Efficient Windows
In the UAE, south-facing facades are subjected to large amounts of solar gain. This can be alleviated by purchasing low-emissivity glazing which reduces heat absorption through windows. Installing climate-efficient windows such as double-glazed windows can keep out the heat during the summer – many manufacturers provide windows with low Solar Heat Gain Coefficient (SHGC). The SHGC refers to a number of factors in the windows construction such as glazing type, coating, and pane to glass ratio, which can affect the amount of solar radiation that enters the building interior.
Clerestory
Architectural features such as clerestories and atriums bring in adequate light into deeper centers inside buildings and rooms.

Reflective Concrete
Reduce heat-island effects by installing reflective concrete for pathways. There is significant payback as reflective surfaces increase overall light levels and enable buildings to use fewer onsite light fixtures.
Shade / Canopy
Schools generally have fewer paved and impermeable surface area than offices in urban districts – however, since playgrounds use artificial surface cover, they are still susceptible to absorbing heat and should be adequately covered.
Shading
Providing plants with shade protects them and leads to less watering.
A number of schools in the UAE prefer to grow their own food, as it provides a great learning opportunity for students to get acquainted about local production, factoring in the climate conditions of the UAE. Examples of climate resilient vegetables are tomatoes, zucchini, basil, and spinach (sabanek) Growing your own herbs, fruits and vegetables can be a very satisfying hobby. It also helps save money, reduce carbon emissions related to artificial fertilizers, pesticides and food transportation, and it improves access to healthy food.

Hardscape:
The use of dark, non-reflective surfaces for parking, roofs, walkways and other hardscapes contributes to the heat island effect – the land absorbs the suns warmth and then radiates it into the surroundings. This can increase surrounding temperatures by 2 to 10 degree F.

Land can be contoured so that irrigation/rain water runoff flows through all planted vegetation ensuring efficient use of water supply.
Mulching and composting conserve moisture/water and also help build good soil. Use brown driplines to blend in with natural color of mulch.
Use driplines with built-in check valves to eliminate excessive losses due to water runoff when implementing sloped and contoured landscape garden.
Use irrigation automatic controller with multiple irrigation programs for different grouped plants. It is recommended to use a remote connection via Wifi and 3G to Cloud based control and the use of weather based water management systems.
The addition of substrate material such as perlite or vermiculite into the soil mix can help with water retention.
Indoor Environmental Quality (IEQ)
With the help of acoustical consultants, schools can greatly improve their students’ learning experience by ensuring better acoustics.
Indoor Air Quality (IAQ)
Establishing good indoor air quality can positively affect student and teacher performance; can reduce absenteeism, and also prevent the potential for long and short-term health problems. Children spend 85% to 90% of their time indoors, and they breathe more air relative to their body size than adults. Hence they are more at risk with indoor pollutants and toxins.
ASHRAE guidelines provide a baseline for good air quality concerning exhaust location, air distribution controls, outside air intakes, and the design of condensate plans. Other steps are listed below:
VOC
Examples of sustainably resourced building materials include: lumber certified to a forest standard, rapidly renewable materials such as bamboo and straw, and metal, etc.
Examples of naturally sourced building material include: stone, bamboo, linoleum, sheep wool (insulation), coconut fiber, adobe, compressed earth etc.
Sustainable building projects can reduce their potable water consumption by designing and installing plumbing systems that can use captured greywater in flush fixtures or provide greywater for landscape irrigation. Dubai Municipality’s Al Sa’fat’s Gold certification requires 15% of onsite greywater to be reused, while the Platinum certification requires 30% reuse of onsite greywater – consult the Dubai Al Sa’fat Rating System and Estidama regulations for more information regarding the installment of residential greywater systems. Insulated floors can regulate cooling demand.
Water Management System
In addition to installing efficient fixtures, building owners can take a step further by installing a water management system which can potentially save significant water as usage is linked directly to its source, which helps target reduction where needed and troubleshooting leakages.

Water consumption rate per person in the UAE is 550 to 850 liters/day which is considered one of the world’s highest rates. Several steps can be taken to reduce this consumption.
Solar Orientation & Heat Gain
Optimize your building’s orientation to maximize south and north facades and reduce exposure to direct solar gain on east and west facades. Locating windows on north-facing walls optimizes natural daylight without the glare that comes from direct sunlight. It also minimizes solar heat gain.
Heat Gain
A discrete distribution of functional zones in the school building can minimize undesirable heat gain. For example, designing thermal buffer zones on the periphery (such as an entrance lobby) will protect main central spaces from overheating.
Climate Efficient Windows
Natural Ventilation
Schools can have design features that utilize natural ventilation: The Estidama rating system recommends the base minimum standards for natural ventilation strategies to be derived from CIBSE AM10:2005. Features such as operable windows, general window distribution – windows located in adjacent walls with a horizontal shift to allow for cross ventilation – and a reasonable increase in window size also provide protection from direct solar gain and enhance natural ventilation.

Passive Design
An energy-efficient school can be achieved in several ways; a few simple passive design strategies can lead to significant reduction and savings.
Radiant Cooling
A Radiant Cooling system (also referred to as Chilled Beam system) can significantly lower the cooling load on a chiller by utilizing water instead of air as the medium of heat transfer in the HVAC system. Chilled beams consume less fan energy, require less ceiling space, and are much quieter. Such systems are expected to lower the chiller cooling load by approximately 20%. Insulated floors can regulate cooling demand.

Insulated floors can regulate cooling demand.
Switch from constant air volume to Variable air volume system by considering variable speed drives. This technology saves energy as it provides air as needed.
The Variable Refrigerant Flow technology uses refrigerants as the medium for cooling. VRF allow for greater energy savings as they only work as needed. VRFs are popular in office buildings.
Absorption Chillers Absorption chillers use heat to drive the refrigeration cycle efficiently and use very little energy.
Water Cooled Chillers
Water cooled chillers are far more energy efficient compared to air cooled chillers, showing about 50% in energy savings.
Heat Recovery Wheel
Mechanisms such as Heat recovery wheels (systems) provide a low cost solution to managing humidity and heat. A heat recovery wheel traps cold air that is being expelled from the ventilation system and turns its energy back around, mixing it with incoming hot air from the outside and cooling it as a result. This simple but efficient technology can substantially reduce the demand for energy to cool a building. Heat recovery wheels can also be used in reverse order when hot energy from expelled hot exhaust air needs to be turned back around inside the building. In addition, Heat/Energy recovery systems are required by the Dubai Al Sa’fat Rating System under section 502.10.
Rooftop Unit
Air-conditioners account for 60-80% of a building’s energy consumption. Regular manufacturer-recommended commissioning of residential AC systems prevents energy wastage from appliances working in unsatisfactory condition, increasing their lifespan whilst preventing premature and costly breakdowns.
Thermostat
Maintaining your air-conditioner’s temperature at 24 degree C reduces pressure on cooling units, reduces monthly bills, and in turn reduces carbon emissions in the atmosphere.
Water Pipes
Insulate all chilled water pipes and all air-conditioing ducts with appropriate insulation materials to minimise heat loss. Additionally, insulate roof and external walls (if possible) to reduce heat gain and lower cooling demand.
We spend 90% of our time indoors, hence it is extremely important to test the quality of indoor air. Common contaminants that are typically found in indoor air include carbon dioxide, formaldehyde, aldehyde, hydrocarbons, mold, pesticides, asbestos, and several known allergens such as dust mints, pet dander and insect parts.
BMS
Implement a Building Management System (BMS). A BMS typically manages mechanical, electrical, and plumbing (MEP) systems which represent 40% of a building’s energy usage. With lighting included, that number can reach up to 70%. BMS systems are a critical component to managing energy demand. Improperly configured BMS systems are believed to account for an additional 20% of the buildings energy usage.
Renewable
Generating onsite energy using sunlight, through solar Photovoltaic systems is an effective means to reducing demand by meeting part or all of a building’s energy needs. In 2016, the Dubai Electricity and Water Authority launched the Shams Initiative which encourages household and building owners to install PV panels to generate electricity.
