Tiong Bahru Heritage Home
Project Overview
A 1950s conservation flat transformed with cross-ventilation corridors and operable clerestory windows. The design preserves architectural character while introducing airflow paths that reduce indoor temperatures by 4-6°C during peak hours. Strategic window placement captures prevailing southwest winds throughout the year.
Key Features
- Floor-to-ceiling louvered doors connecting front and rear spaces
- Elevated clerestory windows for hot air extraction
- Shuttered ventilation grilles maintaining heritage aesthetics
- Reflective white lime wash on exterior walls reducing heat gain
- Ceiling fans positioned along airflow paths for enhanced circulation
Results
The homeowners report comfortable living conditions without mechanical cooling from March through October. Energy consumption decreased by 68% compared to typical air-conditioned flats of similar size. The project received Building and Construction Authority recognition for sustainable heritage conservation.
Tanjong Pagar Office Space
Project Overview
This 280 square meter office on the fourth floor utilizes wind-driven ventilation combined with thermal mass cooling. Motorized windows open automatically based on outdoor temperature sensors. Double-height spaces create pressure differentials that draw air through workstations. The system operates independently for 7-8 months annually.
Key Features
- Automated window actuators responding to temperature and air quality sensors
- Exposed concrete ceilings absorbing daytime heat
- North-south orientation maximizing cross-ventilation potential
- Internal courtyard creating localized wind patterns
- Bamboo sunshades reducing direct solar radiation by 75%
Results
Monthly electricity costs dropped from $2,800 to $950. Staff surveys indicate 87% satisfaction with thermal comfort during natural ventilation periods. The installation paid for itself within 31 months through energy savings and qualified for Green Mark Platinum certification.
Pasir Ris Terrace House
Project Overview
A three-story residence employing stack ventilation through a central light well. Warm air rises through the core and exits via a wind cowl on the roof, pulling cooler air from ground-level gardens. The system moves 2,400 cubic meters of air hourly without fans, creating continuous airflow throughout living spaces.
Key Features
- Central atrium extending from ground floor to rooftop
- Rotating wind cowl extracting air regardless of wind direction
- Ground-level water feature cooling incoming air by evaporation
- Perforated brick walls allowing airflow while maintaining privacy
- Solar-powered exhaust fans boosting stack effect during calm periods
Results
Indoor temperatures remain 5-7°C below outdoor readings during afternoons. The family eliminated air conditioning use in common areas completely. Water consumption increased slightly for the evaporative cooling feature, but overall utility costs decreased by 58% annually.
Katong Shophouse Retrofit
Project Overview
Restoration of a 1920s shophouse incorporating traditional ventilation methods with contemporary materials. Original air wells were reopened and enlarged, while new operable skylights replace fixed glass panels. The narrow floor plan naturally channels breezes from front to rear, supplemented by hidden vents in decorative cornices.
Key Features
- Restored timber jalousie windows with bronze mesh screens
- Reopened internal courtyards creating vertical air channels
- Thermally broken skylights reducing heat gain by 62%
- Reclaimed clay roof tiles with ventilated air gap beneath
- Decorative fretwork panels concealing ventilation pathways
Results
The building now operates comfortably without cooling from November through February and requires minimal air conditioning during other months. Annual energy use decreased from 18,500 kWh to 6,200 kWh. The project won the Urban Redevelopment Authority Architectural Heritage Award for sensitive adaptive reuse.
Changi Business Park Warehouse
Project Overview
A 1,200 square meter industrial facility using ridge ventilators and high-level louvered panels. The 9-meter ceiling height creates strong buoyancy forces that exhaust hot air naturally. Insulated roof panels reflect 85% of solar radiation, while strategically placed doors create cross-flow at worker level. Temperature monitoring shows consistent conditions suitable for light manufacturing.
Key Features
- Continuous ridge ventilator spanning entire roof length
- Motorized high-bay louvers opening during operational hours
- Aluminum composite roof panels with polyurethane foam core
- Large roller doors positioned for optimal airflow patterns
- Destratification fans redistributing trapped warm air
Results
The facility maintains temperatures 8-10°C below standard warehouses without climate control. Worker productivity increased by 12% according to management reports. The company saves approximately $4,200 monthly on electricity costs compared to their previous air-conditioned warehouse of similar size.
Bukit Timah Bungalow
Project Overview
A contemporary residence featuring wind towers inspired by Middle Eastern architecture, adapted for tropical conditions. Four towers positioned at corners capture prevailing breezes and direct them downward into living spaces. Underground ducts pre-cool incoming air by passing it through earth-contact zones before distribution. The system provides whole-house ventilation averaging 8-12 air changes hourly.
Key Features
- Four-directional wind catchers with adjustable dampers
- Underground cooling tubes at 2.5-meter depth
- Double-skin facade creating thermal buffer zone
- Automated louvered windows responding to indoor CO2 levels
- Green roof reducing heat transfer by 40%
Results
Indoor temperatures average 26-28°C throughout the year without mechanical cooling in common areas. The owners use bedroom air conditioning only during sleep hours from May through August. Total energy consumption is 72% lower than comparable homes in the neighborhood. The project received multiple sustainability awards and has been featured in architectural publications.
