Embracing Eco Design: A Philosophy Started with a Detailed Analysis of the Local Natural Environment

Offering an insight into the new design dimensions we are exploring

Eco-Mantra’s eco design, is design that works with the environment to exclude unwanted heat and make use of existing cold basements, take advantage of natural sun, shade and cooling breezes and minimize the need for air conditioning (AC) and artificial lighting. The use of passive design principles in the tropics results in a building that is comfortable, energy efficient and creates substantial savings in running costs of both cooling and lighting.

ESD Environmentally Sustainable Design is a Philosophy that starts with a detailed analysis of the local natural environment.

As a result, we are achieving well integrated buildings with simple systems that work with the natural laws of physics to increase wellbeing, reduce energy consumption and contribute back to the greater environment and its seasonal flows.

Reducing the Urban Heat Island UHI effect and the overall ambient temperature of the public spaces in Jakarta’s new ocean beach walk. The path of the sun changes gradually throughout the year between the summer and winter months. Generally, the best approach in the tropics is to design so that walls are shaded from the sun all year round. Adding passive design features that can naturally remove hot air and maximize fresh breeze, building on stilts, making use of cold basements and colder shaded areas, maximizing airflow. Combined, the measures reduce the entire sites ambient temperatures.

Happiness and well-being are directly linked to the microclimate of every destination. Improving the ambient temperature results in higher levels of asset utilization and improve tenants’ revenues and reduces their costs for excessive air conditioning and cooling too. At Mantra we envision that Batavia PIK Jakarta, will become a showcase for eco design, especially passive design in Southeast Asia.


Seaside Collective Lombok – together with Tampah Hills (TH), Patricia De Osma, Miguel Quezada Diaz Morales, landscaping and choosing materials for a cool built environment

To many hard surfaces of streets, driveways, parking areas and paving around buildings, absorb heat and then re-radiate it, creating a hotter microclimate. The combined effect of hard surfaces at Tampah Hills, Lombok is known as the urban heat island effect. It is responsible for noticeable increase in temperature in the resort area if property owners choose to build with too much concrete.

The Seaside Collective is choosing natural and recycled and reclaimed wooden building materials over concrete and has much lower embodied carbon and a reduced urban heat island effect. By studying the local microclimate, external temperatures can be reduced by over 5 degrees Celsius, preparing the destination for climate change and future client demands. Reducing the ambient temperature, reduces operating time of tenant’s AC’s.

Reducing the amount of potable water used and reducing the amount of wastewater going to treatment plants, reduces greenhouse gas emissions and reduces the electricity and water cost. Recycled water can be used instead of drinking quality water for non-potable uses such as garden irrigation, air-cooling towers and toilet flushing. Rainwater can be collected for pool landscapes and indoor appliances and even to make drinking water for the entire park and its staff and guests. The old model of take, use and waste should soon become obsolete as more destination owners demand their properties become regenerative and less extractive and wasteful.
