Challenge Statement Details

Low carbon transition

  • #1 How might we achieve onsite clean energy solutions for existing buildings?

    Challenge Description

    Onsite clean energy presents an opportunity for building owners to diversify its energy source and minimise its carbon emission. Clean energy can be generated from waste heat recovery, solar thermal collector, photovoltaic panels, wind turbines, hydrogen fuel cell etc.

    While technological advancements have raised standards on safety and performance, not all solutions can be cost effectively deployed at all locations due to varying reasons (e.g. minimum system size for deployment, low solar irradiance).

    CapitaLand seeks onsite clean energy innovations that are efficient, effective, commercially viable and safe for deployment within limited space in our existing properties.

    Pain Points

    • Limited space for onsite installation at existing building and competing use of said limited space (e.g. urban farming versus solar panel installation)
    • Limited availability of renewable energy sources at certain properties (e.g. properties in urbanised area might have limited opportunity for wind power or thermal power)
    • Limited cost effective and efficient technologies to harness renewable energy

    Solution requirements

    We seek solutions for onsite clean energy generation for the portfolio of CapitaLand’s properties that meet the following requirements:

    • Occupant experience - occupants’ comfort and experience in the building are not compromised
    • Small installation footprint - suitable for installation within limited space available in our existing properties
    • Carbon reduction - measurable reduction in carbon emission
    • Cost efficient - strong financial benefits relative to its cost
    • Ready to pilot - at least Technological Readiness Level 6 with proof of concept

    Opportunity areas

    Opportunity areas include but are not limited to

    • Recovery of waste heat
    • Building integrated solar PV or modular PV panels of high capacity output or co-location of solar PV with rooftop farming
    • IOT solutions that track, optimise and enhance efficiency of onsite energy generation

  • #2 How might we achieve significant reduction in energy consumption for existing buildings?

    Challenge Description

    Low-energy buildings are characterised by energy-efficient design and systems that provide high standards of occupant comfort at low energy consumption. A combination of passive strategies (e.g. solar shading, natural ventilation, daylighting), active strategies (e.g. energy efficient HVAC, energy efficient artificial lighting), and energy management (e.g. building automation, smart control, and plug-load management) can be adopted to significantly reduce an existing building energy consumption. However, not all solutions can be effectively deployed at an existing building given its site constraints.

    CapitaLand seeks innovations and technologies that can push the boundaries of energy efficiency in buildings as we strive towards super-low energy beyond highest rating in national green building standards across the globe.

    Pain Points

    • Costly to further improve energy efficiency that are already fairly energy efficient (e.g. buildings that have already attained national level green ratings)
    • Existing portfolio of buildings with different HVAC systems (e.g. buildings with mixture of centralised and split units, buildings with only split units) and varied building management systems
    • Existing portfolio of buildings in various stages of energy efficiency
    • Limited opportunities to improve energy efficiency due to site constraints (e.g. age of the buildings)
    • Hard to achieve optimal indoor thermal comfort conditions due to varying weather conditions, occupancy and individual thermal comfort preference

    Solution requirements

    We seek solutions that significantly reduce energy consumption for the portfolio of CapitaLand’s properties that meet the following requirements:

    • Measurable and trackable - clear calculation methods of energy consumption and auditable data
    • Occupant experience - occupant comfort and experience in the building are not compromise
    • Relative ease of implementation - implemented with minimal disruption to business operations
    • Small installation footprint - suitable for installation within limited space available in our existing properties
    • Carbon reduction - measurable reduction in carbon emission
    • Cost efficient - strong financial benefits relative to its cost
    • Ready to pilot - at least Technological Readiness Level 6 with proof of concept

    Opportunity areas

    Opportunity areas include but are not limited to

    • Best in class energy efficient solutions that optimise heating, ventilation, and air-conditioning (HVAC) and lighting
    • Efficient energy management
    • Building material innovations for insulation

Water conservation & resilience

  • #3 How can we adopt new ways of water management in existing properties in order to detect abnormalities in the water usage pattern and/ or leakages?

    Challenge Description

    Abnormalities in water usage and leakages if left undetected lead to unnecessary water usage and increase in operating costs. Such incidences could happen anytime anywhere. It could arise due to irresponsible user behaviour and/or aging or extensive use of water fixtures, tubing, valves and other components areas in the building (e.g. Air- conditioned spaces, restrooms, chilled water plant rooms). Existing IOT solutions come at a high cost of implementation, while water monitoring and leakage detection solutions often involve installation of multiple monitoring devices and extensive cabling.

    To continue to improve water efficiency and reduce water wastage at our properties, CapitaLand seeks innovations and solutions that could cost effectively detect abnormal water usage and leakage.

    Pain Points

    • High cost of implementation of water leakage detection solutions(e.g. number of fitting, devices and cablings involved)
    • Difficulties in detecting water leakage in concealed pipes
    • No strong return on investment for monitoring devices/systems as there will be tangible cost savings only when there is rectification of an actual leak

    Solution requirements

    We seek solutions to detect changes in water usage patterns and/or leakage for the portfolio of CapitaLand’s properties that meet the following requirements:

    • Accurate leak analysis - Risk based approach to effectively monitor water consumption and identify location of water leakage
    • Timely detection - Near real time detection of leaks or abnormal water consumption
    • Cost efficient - strong financial benefits relative to its cost
    • Ready to pilot - at least Technological Readiness Level 6 with proof of concept

    Opportunity areas

    Opportunity areas include but are not limited to

    • IOT sensors
    • Video analytics
    • Water management platforms

  • #4 How might we reduce potable water usage in existing buildings with water harvesting and/or recycling methods?

    Challenge Description

    Water scarcity and poor access to potable water have driven building owners to search for alternate sustainable source of water. Greywater can be reclaimed for reuse. Rainwater can also be harvested and treated for higher value usage. However, integration of such alternate water supplies into existing properties typically require significant retrofitting of pipes and storage systems.

    CapitaLand would like to explore innovative solutions and technologies to use alternative sources of water, taking into consideration the existing piping and infrastructure in our existing buildings.

    Pain Points

    • Limited space for water storage and treatment in existing buildings
    • Untreated rainwater is not drinkable and may lead to health issues if used as replacement of potable water; at some properties, rainwater is collected for irrigation purposes only
    • Unsteady supply of rainwater as it is highly dependent on geography and seasonal changes
    • Difficult and costly to install additional water piping system for alternate water source (e.g. recycled greywater, treated rainwater)

    Solution requirements

    We seek solutions to harvest and recycle water for the portfolio of CapitaLand’s properties that meet the following requirements:

    • Ease of integration in existing buildings - collection, piping and treatment of water without major retrofit works
    • Small installation footprint - suitable for installation within limited space available in our existing properties
    • Cost efficient - strong financial benefits relative to its cost
    • Multiple purpose - collected/treated water to have multiple applications (e.g. shower, drinking, washing, flushing)
    • Energy efficient/low carbon - low carbon footprint and consume reasonable amount of energy
    • Ready to pilot - at least Technological Readiness Level 6 with proof of concept

    Opportunity areas

    Opportunity areas include but are not limited to

    • Greywater / rainwater harvesting for uses beyond irrigation, (e.g. toilet flushing and shower)
    • AHU condensate recycling
    • Atmospheric water generator

Waste management & circular economy

  • #5 How might we better segregate waste at source for recycling or treatment?

    Challenge Description

    Waste segregation is an integral part of proper waste management that requires cooperation from multiple stakeholders along the value chain. While dedicated recycling bins are deployed at CapitaLand properties, the challenge resides in raising consumer awareness and behaviour around segregation and recycling. There are also innovations such as image recognition, artificial intelligence and robotics to separate waste post-collection, but these solutions are expensive to implement and may not be effective if contamination of recyclables materials has already occurred.

    Properly segregated waste can be valuable resource inputs into other value chains. Reframing waste as resources can create new business models that maximise value from waste, leading to new markets for products and materials recovered from waste.

    CapitaLand seeks to explore new solutions and technologies that can be deployed to reshape consumer behaviour and incentivise waste segregation efficacy at source for recycling and treatment.

    Pain Points

    • Hard to implement effective measures to influence behaviour and habits of users (e.g. guest in service apartments, tenants in shopping mall)
    • Lack of means to clearly measure and demonstrate the benefits of waste segregation (e.g. food and non-food waste; recyclables and non-recyclables)
    • Lack of means to clearly communicate the importance of individual responsibility and impact on waste segregation
    • Difficult to enforce waste segregation even if it is a mandatory requirement
    • Labour intensive process during backend waste sorting if segregation is not performed properly at source
    • Lack of incentive and motivation for customers to cooperate and play their part on waste segregation
    • Existing solutions are either low impact (I.e. recycling bins) or too expensive to implement (I.e. AI/robotic waste segregation)

    Solution requirements

    We seek solutions to improve the efficacy of recyclable waste (e.g. food waste, plastic waste) segregation at source for the portfolio of CapitaLand’s properties that meet the following requirements:

    • Call to action - solutions that include educating and engaging stakeholders in waste segregation
    • Measurable and trackable - clear calculation methods of increase in properly segregated waste and/or lower level of recyclable waste contamination and auditable data
    • Cost efficient - strong financial benefits relative to its cost
    • Ready to pilot - at least Technological Readiness Level 6 with proof of concept

    Opportunity areas

    Opportunity areas include but are not limited to

    • Cost effective solutions to detect waste that are not recyclable and/ or contaminated at source
    • Cost effective solutions to detect and separate waste that are not recyclable and/ or contaminated post collection
    • Incentive and engagement models that could positively influence user behaviours

  • #6 What is a viable circular economic solution that CapitaLand can introduce to manage resources and waste across its properties and construction sites?

    Challenge Description

    Venturing beyond the existing take-make-waste economic model, a circular economy (also referred to as “circularity”) is a concept aimed at limiting waste and promoting the continual use of resources. It employs reuse, sharing, repair, re-create and recycling to create a closed-looped economic system.

    Waste from building occupants and users such as guests in serviced apartments, shoppers and tenants in shopping malls, and tenants in office buildings present an untapped potential for circularity. There could similarly be opportunities for circularity for construction waste. Currently, the challenges faced are in forging the right partnerships to create an ecosystem for circularity and solutions that can cost effectively repurpose one’s waste into high-value products.

    CapitaLand seeks innovations for circularity to reduce pressure on environment, improve security of raw materials supply, and deliver long term economic value

    Pain Points

    • Challenging to identify the right motivation to incentivise occupants and stakeholders to recycle waste due to the perceived low values of recycled waste
    • Limited options to recycle or reuse or repurpose waste into higher value products
    • Lack of traceability and verification processes on origin of waste
    • Lack of incentives for stakeholders to identify technologies and solutions that establish partnerships with other companies and create the close-looped circular system

    Solution requirements

    We seek solutions to enhance circularity for the portfolio of CapitaLand’s properties/sites that meet the following requirements:

    • Measurable and trackable - clear calculation methods of circularity and auditable data
    • Enhanced ecosystem for circularity - Partnerships, programs, platforms and/or solutions to close the loop
    • New channels for circularity - new ways to reuse, share, repair, recreate or recycle to enhance value of waste
    • Carbon reduction - measurable reduction in carbon emissions
    • Cost efficient - strong financial benefits relative to its cost
    • Ready to pilot - at least Technological Readiness Level 6 with proof of concept

    Opportunity areas

    Opportunity areas include but are not limited to

    • Platform for circularity
    • Waste tracing, monitoring and management
    • On-site solutions to generate higher valued product from waste
    • New uses for construction and other waste generated in the buildings

Healthy & safe buildings

  • #7 How might we improve indoor air quality (IAQ) to enhance wellness of users in our existing buildings?

    Challenge Description

    Indoor air quality (IAQ) is affected by outdoor air quality (e.g. haze, air pollution), building management practices(e.g. selection of building materials, air treatment in air-conditioned space) and occupant behaviour (e.g. preference in keeping doors/windows open). With Covid-19, building occupants and users are now paying even more attention on IAQ.

    Current solutions to monitor and improve IAQ are mainly effective in small enclosed areas. CapitaLand owns and manages different types of properties with characteristics such as large indoor space, multiple building entrances and high footfall, making it challenging to monitor and control IAQ. Green building design with extensive naturally ventilated common areas and multiple entrances to air-conditioned tenanted spaces may also increase possibility of polluted outdoor air infiltration.

    While CapitaLand has deployed measures like IAQ sensors, high grade air filters, purging system, ultra violet germicidal irradiation air handling units to monitor and improve IAQ at our properties, CapitaLand continues to look for innovations to enhance the health and well-being of our building occupants and users.

    Pain Points

    • Limited space for onsite installation in existing building
    • Not all solutions that benefit IAQ are energy efficient or have low carbon footprint
    • Limited cost effective and proven technologies
    • Hard to quantify the benefits
    • Small coverage area of IAQ sensors/solutions
    • Poor accuracy of IAQ sensors
    • Hard to control human behaviour (e.g. PM2.5 is higher when the window is always opened)
    • Difficulty to reduce outdoor air infiltration through building entrances without compromising the building design

    Solution requirements

    We seek solutions to improve the monitoring, visualisation and/or treatment of IAQ for the portfolio of CapitaLand’s properties that meet the following requirements:

    • Occupant experience - improve occupant comfort, wellness and experience in the building  
    • Ease of integration with existing buildings - no major retrofit works required and able to work in spaces where there is frequent infiltration of outdoor air
    • Small installation footprint - suitable for installation within limited space available in our existing properties
    • Energy efficient/low carbon - low carbon footprint and consume reasonable amount of energy
    • Measurable and trackable - clear computation of benefits and auditable data
    • Cost efficient - strong financial benefits relative to its cost
    • Ready to pilot - at least Technological Readiness Level 6 with proof of concept

    Opportunity areas

    Opportunity areas include but are not limited to

    • IOT solutions that are effective and accurate over wide coverage area for monitoring and visualising IAQ and infiltration of outdoor air
    • Air Handling Units enhancements
    • IAQ treatment
