summary of research
this video showcases a variety of features that has been implemented for the Zero Energy Building at BCA Academy to produce enough energy to sustain itself. the building is used for offices and classrooms, as well as other school facilities. it is the first Zero Energy Building retrofitted from an existing building in Southeast Asia. from this video,we have learnt of some features that we could possibly implement in our building to produce more energy/ cut down on the usage of energy, all while being environmentally friendly. ~~ example sketch  this is a sketch done by someone else. we used this as a sort of 'guideline' for the minimum requirements of our design(s).  this is a very detailed floor plan of various floors of a building. ~~ ZEB @ BCAA website these are the features that were included in the ZEB: cooling systems/features air-conditioning system displacement cooling personalised ventilation single fan twin coil system solar-assisted stack ventilation system greenery systems lighting system (light pipes, light shelf, mirror ducts and lighting management system) shading devices solar panels ~~ Definition of a Green Building a green building(also known as green construction or sustainable building) refers to a structure and using process that is environmentally responsible and resource-efficient throughout a building’s life-cycle: sitting, designing, construction, operation, maintenance, renovation and demolition. this requires close cooperation of the design team, the architects, the engineers and the client at all project stages. ~~ Green Features implemented in the National Library Building the orientation of the building away from the East-West sun, combined with sun-shading features on the West face of the building as an additional shield against solar heat gain and glare makes it a green building. sun-shading features include: ღlow-emissive double-glazed glass panel facadeღ ღlarge overhangs on external facadeღ ღlight shelves that extend into the library space reflect sunlight further into the buildingღ these features optimize daylight and thus, reduce use of artificial lighting. ღღღ energy efficient features include: ღdaylight sensorsღ (that are used together with) ღautomatic blinds at the building facadesღ ღpublic toilets installed with motion sensorsღ ღenergy efficient lightingღ (that are switched on only when required after closure of library) ღღღ water efficient features include: ღuse of rain sensorsღ as part of the automatic irrigation system for landscaped areas ღwater efficient taps and cisternsღ (used to conserve water) ღextensive landscapingღ ღsky terracesღ ღroof gardensღ *the last three are utilized to lower local ambient temperature.* ღღღ cooling features include: ღnight setback for air-conditioning system in the library spacesღ (after library operation hours with automated chiller controls) ღan open Plaza area at the first storeyღ (for admission of natural ventilation and day lighting) ღa stack effect at the open Plazaღ (i.e. the air from the sides of the building is drawn upward between the link bridges and in-between the two blocks) ღenergy monitoringღ (via Building Management System) ♥♥♥♥♥
final design of the building      a sketch of the front view of the building- -in 3D, because everyone knows 3D makes everything better :P ♥♥♥♥♥♥
details of the features in the building light shelves
 a sketch on how a light shelf works by ♥Arabella Lapitan♥ what's a light shelf? a light shelf is a passive architectural device that permits daylight to enter deep into a building. light shelves may be interior or exterior; exterior light shelves may also function as sunshades. what does a light shelf do? light shelves reflect sunlight into the building so less artificial lighting (like lamps and bulbs) are needed. they also provide shade from direct sunlight. light pipes
 how a light pipe works by ♥APS Physics♥ what is a light pipe? a light pipe allows daylight to be reflected by mirrors into a building. how does it work? daylight is transmitted by reflection through vertical light pipes. daylight is released through ceiling openings up to 5 meters below the roof. sunlight should be reflected into the building from the rooftop, so less artificial lighting is need at the top. mirror ducts
 how a mirror duct works by ♥TK Works♥ what does a mirror duct do? it reflects sunlight into the building so less artificial lighting is needed. what is it made up of? it has: lighly reflective material, no mechanical parts what does it use as a power source? no power is needed to run it. high performance glazing
what's high performance glazing? high performance glazing is the installation of different glass types to reduce the amount of sunlight entering the building directly, so lesser energy is needed to keep the building cool. low e glass  how low e glass works by ♥Impact Safety Glass Works Pvt. Ltd.♥ how does low e glass help? by installing low e glass, the transfer of solar radiation into the building can be reduced by the low emissive coating on the glass double glazed units  how double glazing units work by ♥David Gordon♥ how does a double glazed unit help? by installing the double glazed unit, transfer of solar radiation is reduced, so lesser energy is needed to warm the building when needed. what is it made up of? it consists of a dry vacuum sandwiched between glass sheets. solar film coating  how solar film coating works by ♥Tint Wise - Window Tinting Experts♥ how does solar film coating help? solar film coating is effective in reducing harmful ultraviolet rays and repelling solar heat, so lesser energy is needed to cool the building. shading devices
 types of shading devices for non-southern exposures by ♥The American Institute of Architects♥ and ♥Society of Building Science Educators♥ on a ♥project website♥ how do shading devices help? by installing shading devices to windows, heat gain from the sun into the building is reduced while still allowing diffused daylight to enter. canteen
how is it kept cool? it has: high ceilings ventilation air vents to suck out hot air from kitchens fans around the area gym
how is it kept cool? it has: high ceilings ventilation fans around the area windows that are open to let wind come in and for ventilation science labs
how is it kept cool? it has: fans around the area windows that are open to let wind come in and for ventilation staff room
how is it kept cool? it has: air-conditioning displacement cooling (warm air rises and is extracted by extract grilles. cool and clean air is supplied via diffusers on the raised floor. warm and cool air will not mix until it comes into contact with heat loads in the room, such as humans.) auditorium
how is it kept cool? it has: air conditioning displacement cooling (warm air rises and is extracted by extract grilles. cool and clean air is supplied via diffusers on the raised floor. warm and cool air will not mix until it comes into contact with heat loads in the room, such as humans.)  this is a design implemented in the ZEB. library
how is it kept cool? it has: air conditioning displacement cooling (warm air rises and is extracted by extract grilles. cool and clean air is supplied via diffusers on the raised floor. warm and cool air will not mix until it comes into contact with heat loads in the room, such as humans.) this is a design implemented in the ZEB. building how is it kept cool? it has: greenery plants that will be planted around the external of the building (e.g vines) eco-garden on rooftop aforementioned features above such as high performance glazing and shading devices    these are some designs implemented in the ZEB. how is it kept eloquently (sufficiently) lit? it has aforementioned features such as light shelves and light pipes how is the water efficiently used? rain water collection is implemented. rain water collected over time is supplied to toilets for flushing to save the use of clean drinkable water. if there is not enough water collected, water from the water tank is used instead. how is electricity supplied usefully and efficiently? the building has solar panels. solar panels will not only be installed on the rooftop but also all around the external of the building. if there is no sun that day, electricity will be taken from the power grids. if there is excess electricity produced, electricity will be sent to be stored in the power grids.  this is a first generation solar panel implemented in ZEB.  this is a second generation solar panel implemented in ZEB. how is electrical use reduced? it has: motion sensors. when no motion in the area is sensed, light, fans and air-conditioners will be switched off. temperature sensors. if a temperature drop is sensed in the area, cooling devices will be turned down, and vice versa. welcome to our blog.
