DEVELOPING INNOVATIVE STRATEGIES FOR RETROFITTING PERSONAL FANS IN EXISTING AIR-CONDITIONED OFFICE BUILDINGS: ADVANCING THEORIES AND MODELS FOR PERSONALIZED COMFORT AND ENERGY SUSTAINABILITY

VIEW INFOGRAPHICS

Research

TO ALIGN WITH MALAYSIA’S ENERGY EFFICIENCY AND CONSERVATION ACT (EECA), THIS RESEARCH EXPLORES INTEGRATING PERSONAL COMFORT SYSTEMS (PCS), SUCH AS PERSONAL FANS, WITH CENTRALIZED ACMV SYSTEMS TO REDUCE OFFICE ENERGY CONSUMPTION WHILE MAINTAINING OCCUPANT COMFORT. THROUGH EXPERIMENTAL TESTING INVOLVING THERMAL MEASUREMENTS, SATISFACTION SURVEYS, AND INFRARED THERMOGRAPHY, ALONGSIDE BUILDING ENERGY SIMULATIONS, THE STUDY EVALUATES FAN RETROFITTING STRATEGIES. A TECHNOECONOMIC ANALYSIS MEASURES POTENTIAL ENERGY SAVINGS, ULTIMATELY ADVANCING DATA DRIVEN MODELS FOR PERSONALIZED COOLING TO ESTABLISH EFFECTIVE RETROFITTING STRATEGIES FOR SUSTAINABLE OFFICE BUILDINGS IN COMPLIANCE WITH NATIONAL ENERGY GOALS.

MONTE CARLO-ENABLED PROBABILISTIC MODEL FOR PREDICTING MINERAL–ESTER OIL MIXTURE PROPERTIES IN RETROFILLING SCENARIOS

VIEW INFOGRAPHICS

Research

TRANSFORMER INSULATING OIL IS ESSENTIAL FOR THE COOLING AND DIELECTRIC INSULATION OF POWER TRANSFORMERS. OVER TIME, THIS OIL DEGRADES DUE TO THERMAL, CHEMICAL, AND ELECTRICAL STRESSES, AFFECTING RELIABILITY AND SAFETY. IN RECENT YEARS, RETROFILLING AGED MINERAL OIL WITH SYNTHETIC ESTER OIL, HAS GAINED ATTENTION AS A SUSTAINABLE APPROACH TO IMPROVE INSULATION PERFORMANCE AND EXTEND ASSET LIFE. HOWEVER, MOST STUDIES EVALUATING RETROFILLING PROVIDE LIMITED EXPERIMENTAL DATA AND RELY ON DETERMINISTIC ANALYSES THAT DO NOT ACCOUNT FOR THE VARIABILITY AND UNCERTAINTY ARISING FROM AGED MINERAL OIL PROPERTIES AND MIXED-OIL BEHAVIOUR. THIS RESEARCH PROPOSES A MONTE CARLO–BASED PROBABILISTIC PREDICTION MODEL FOR TRANSFORMER OIL MIXTURES INVOLVING AGED MINERAL OIL (AMO) AND FRESH SYNTHETIC ESTER OIL (SEO). THE STUDY WILL USE EXISTING EXPERIMENTAL DATA FROM MIXTURES OF AMO AND SEO. THE AMO IS SUBJECTED TO ACCELERATED THERMAL AGING AT 130 °C FOR DURATIONS OF 75, 150, AND 225 HOURS. IT WAS THEN MIXED WITH NEW SEO AT MIXING RATIOS OF 3%, 5%, 7%, AND 9%. MEASURED PROPERTIES INCLUDE BREAKDOWN VOLTAGE, WATER CONTENT, AND ACIDITY. IN THIS RESEARCH, REGRESSION-BASED MODELS WILL FIRST BE DEVELOPED TO DESCRIBE THE RELATIONSHIP BETWEEN AGING DURATION, MIXING RATIO, AND EACH MEASURED PROPERTY. THESE REGRESSION EQUATIONS FORM THE BASIS HOW EACH PROPERTY EVOLVES OVER TIME AND COMPOSITION. MONTE CARLO SIMULATION WILL THEN BE APPLIED TO INCORPORATE THE UNCERTAINTIES OBSERVED IN EXPERIMENTAL MEASUREMENTS AND PARAMETER ESTIMATION, PRODUCING A PROBABILISTIC DISTRIBUTIONS OF PROPERTY OUTCOMES INSTEAD OF A SINGLE DETERMINISTIC VALUE. THE PROBABILITY DISTRIBUTIONS GENERATED FROM THESE SIMULATIONS WILL PREDICT THE LIKELIHOOD BEHAVIOR BETWEEN AND BEYOND THE TESTED AGING PERIODS. COMPARED TO TRADITIONAL DETERMINISTIC APPROACHES, THE MONTE CARLO METHOD IS EXPECTED ABLE TO PROVIDE A MORE COMPREHENSIVE PREDICTIVE CAPABILITY, ALLOWING ENGINEERS TO ANTICIPATE PROPERTY VARIATIONS UNDER DIFFERENT CONDITIONS AND OPTIMIZE FUTURE RETROFILLING AND MAINTENANCE STRATEGIES.

ELUCIDATING THE ADSORPTION MECHANISMS OF METHYL ORANGE (MO) DYE USING SUGARCANE BAGASSE CELLULOSE-NANOCLAY COMPOSITE (SBC-NC) AEROGEL FOR SUSTAINABLE TEXTILE WASTEWATER TREATMENT

VIEW INFOGRAPHICS

Research

MALAYSIA`S GROWING TEXTILE INDUSTRY GENERATES DYE WASTEWATER CONTAINING PERSISTENT POLLUTANTS SUCH AS METHYL ORANGE (MO), WHICH CONTRIBUTES TO INTENSE COLOUR, HIGH PH, TSS AND COD. THIS PROJECT DEVELOPS A SUSTAINABLE SUGARCANE BAGASSE CELLULOSE–NANOCLAY (SBC–NC) AEROGEL FOR MO REMOVAL THROUGH ADSORPTION. THE AEROGEL IS CHARACTERIZED USING FTIR, SEM, XRD, TGA AND BET ANALYSES. ADSORPTION CONDITIONS, KINETICS AND ISOTHERMS WILL BE EVALUATED, ALONGSIDE REGENERATION AND REUSABILITY. THE PROPOSED SBC–NC AEROGEL TRANSFORMS AGRICULTURAL WASTE INTO A COST-EFFECTIVE ADSORBENT THAT IMPROVES TEXTILE WASTEWATER TREATMENT, STRENGTHENS REGULATORY COMPLIANCE AND ADVANCES MALAYSIA’S GREEN TECHNOLOGY AGENDA.

INVESTIGATING SOLIDIFICATION/STABILIZATION MECHANISMS OF ELECTROPLATING SLUDGE IN GREEN CONCRETE WITH COCKLE SHELL-BASED SUPPLEMENTARY CEMENTITIOUS MATERIALS FOR SUSTAINABLE CONSTRUCTION MATERIALS

VIEW INFOGRAPHICS

Research

THIS PROJECT PIONEERS THE USE OF CALCIUM CARBONATE-RICH COCKLE SHELL ASH AS A SUPPLEMENTARY CEMENTITIOUS MATERIAL TO SOLIDIFY/STABILIZE HAZARDOUS ELECTROPLATING SLUDGE (SW 204) WITHIN GREEN CONCRETE. IT INVESTIGATES THE CHEMICAL AND MICROSTRUCTURAL MECHANISMS OF HEAVY METAL IMMOBILIZATION, EVALUATES MECHANICAL STRENGTH AND LEACHING BEHAVIOUR, AND APPLIES ARTIFICIAL NEURAL NETWORK MODELLING TO OPTIMIZE MIX PROPORTIONS. THE EXPECTED OUTCOME IS A SCALABLE, LOW-CARBON CONSTRUCTION CONCRETE THAT SAFELY REPURPOSES TWO ABUNDANT INDUSTRIAL AND MARINE WASTES, ADVANCING CIRCULAR-ECONOMY WASTE MANAGEMENT AND SUSTAINABLE CONSTRUCTION ALIGNED WITH MALAYSIA'S CLIMATE GOALS.
