Building Envelope Energy Conservation

Building is arranged to avoid northeast monsoon, but faces western direct sunshine. By using C shape building type and stepping back overhang from 8th level to third level to create rich shadow. Moderate opening lets less sunshine penetrate through, and double decks in roofing construction which creates great insulation, makes this building an excellent work for low solar heat gain.

Ice Thermal Storage Air Conditioning Design

Besides assigning proper number of chillers, this air-conditioning system adopts ice thermal storage technique, to make ice at night with lower cost of electricity, and to melt ice in the daytime instead of operating the major system. And finally, reduces peak electricity consumption and energy cost.

Illumination Energy Conservation

Equipped with high efficiency illumination, this building adopts electronic stabilizer and achieves energy efficiency.

Building Envelope Energy Conservation

This project is not only rich in biodiversity, hybrid planting, and multi-latitude planting, but also cultivates more than 26species of aboriginal plantings. Proper soil depth and planting density makes plantings grow even better. Constructed wetland provides sustainable habitat for frogs, dragonflies, and fireflies. In planting and biodiversity, undoubtedly it is a successful case.

Building Envelope Energy Conservation

Besides low building ratio, most pavements in the building site are water permissible. Three rain water-collecting ponds and ecological wetlands provide more water retention storage, delay possible city flood, but also regulate microclimate-truly a distinguished example for of water retention.

Building Envelope Energy Conservation

Recycled water is between tape water and sewage, reusable water. Environmental Examining Building deals not only with its own daily wastewater, but also commissioned by Minister of Education to purify concentrate collected from college laboratories, very significant case of waste water recycling. Recycled water can flush the toilets, create regulating ponds for landscape purpose, and be good resource in gardening.

Building Envelope Energy Conservation

Although building site is spacious, soil excavation and refill expects to achieve balance within the site, no extra soil need to be moved to the dumpsite. During the construction, strict environmental conservation related work was carefully executed. For example: noise and vibration control, sewage management, waste management, environmental observation, environment recovery after construction to comply with the related environmental codes, and greatly reduce the construction waste.

Building Envelope Energy Conservation

This building is a steel structure, and is lighter than prevailing RC structures in Taiwan. Lightweight building usually reduces building materials to achieve CO2 reduction, energy conservation, and natural resource preservation. Besides, systematic way of construction was adopted in building process: By using pre-cast PC panel, semi pre-cast KT floor, lightweight dry walls, and unit bathroom etc. This building sets the goals to reduce construction materials, reduce CO2, and to reduce construction pollution. These design thoughts and results sets excellent examples for others to follow.

Building Envelope Energy Conservation

Building and Energy Management System can overcome minor design insufficiency, reduce unnecessary energy consumption due to personal behavior, like laziness or ignorance. This building uses BEMS system with manual control, to reduce contract electricity consumption, reduce chillers loading, heighten air-conditioning temperature, heighten water temperature in chiller outlet, and achieve 2nd year 19% less electricity consumption than the first year, and 5% even less in the third year than the 2nd year.
