“Green BIM Microclimate Data Platform”, sponsored by Delta Electronics Foundation, doubles the data coverage of meteorological stations and helps National Museum of Marine Science & Technology shave electricity consumption by 10%


Launched by Delta Electronics Foundation (DEF), Central Weather Bureau (CWB), Taiwan Architecture & Building Center (TABC), and International Climate Development Institute (ICDI), the "Green BIM Microclimate Data Platform" has functioned in climate data provision for architects since 2017. On 8th May, the database was updated to double its data coverage from the original 13 meteorological stations to 26 ones. The expansion makes meteorological data in each county and city of Taiwan all available online, and helps architects create energy-efficient building designs with higher accuracy. The energy-saving performance of the National Museum of Marine Science & Technology (NMMST), achieved by applying meteorological data to its AC control, was additionally disclosed. With the application, electricity consumption during the peak time of summer days was shaved by 10%; under the optimized operation, the reduction could even reach 30% during spring and autumn. All these achievements have been shown in an online presentation, coupled with videoed remarks and experience sharing from the founder of DEF, the deputy director-generals of CWB, the chairman of TABC, Pro. Chen of National Taiwan University, and the curator of NMMST.

Mr. Bruce Cheng, the founder of DEF, said in the presentation, "Buildings account for 51% of global electricity consumption. Supposing energy-saving designs could be done in advance according to microclimate data, buildings would have great potential to reduce the electricity demand. Besides, the data can be applied to control energy-intensive equipment in existing buildings, further helping curtail energy use during peak hours and electricity expenses."

Mr. Chen, the professor of National Taiwan University and project leader of Green BIM, also claimed, "The database has been highly recognized by many experts and construction companies after its establishment. Last year, we extended the application of this service to the climate adaptation field by offering NMMST weather forecasts."

Over the past year, DEF had collaborated with NMMST to manage AC systems with microclimate data. The daily temperature and humidity are the main determinants of when different types of AC should be activated. Overall, the data application makes electricity consumption be decreased by 10% during peak hours of summer days and potentially 30% in spring and autumn. This significantly cut down on the electricity expenditures of NMMST. 

Currently, Taiwan is on the track to cut the emission by 2% below those of 2005, and further targets a 10% reduction by 2025. To facilitate the goal achievement, DEF has partnered with meteorological and building construction units four years ago, to convert the meteorological data of densely populated areas into parameters compatible with the building information model (BIM). It has covered dozens of data that include solar radiation, wind velocity, temperature, humidity, rainfall, etc., and enables architects to design green and energy-efficient buildings more adapted to local conditions. To date, there have been lots of architects benefitting from the database. The "Green BIM" project is also enhancing the data accuracy through doubling the coverage of meteorological stations and making data in each county and city of Taiwan accessible to the public. 

The next step of the "Green BIM Microclimate Data Platform" is to integrate multiple environment information into the website. Meanwhile DEF is broadening the data application in public and commercial buildings of different counties and cities. The test points are projected to show how microclimate data automatically dominates the operation of energy-intensive and renewable energy equipment.
