House X is a 2-story house with 200 SQM of indoor living space composed of 3 bedrooms, 3 bathrooms, and an open living space with a dining area and kitchen. From a financial and technical point of view, to maintain cool and clean air throughout the house for 24 hours a day, every day, in every single room, the house consumes a stunning 5,400 kWh a year, equal to 2,000 THB a month, which is a record low in this part of the world. In comparison, a modern but conventional house of similar size and usage would expend 32,400 kWh a year, or 10,000 THB a month. And this is aside from all the other benefits generated by the system, such as permanent comfort and health improvement aspects. To this list of benefits, we can also add the entitlement to an on-going accumulated “carbon credit” that will be distributed to more and more property developments as a reward for contributing to the future of the “green economy”.
