Net-zero Learning Resource Centre

DN2953 – GREEN & SUSTAINABLE DESIGN STRATEGIES PROJECT: NET-ZERO LEARNING RESOURCE CENTRE DN 2953 GREEN & SUSTAINABLE DESIGN STRATEGIES GERALYN TOH 192902Z GREEN BUILDING DESIGN

Located beside a creek and shaded by the neighboring hills on the east side and the west side, the Learning Resource Center's (LRC) design takes on a “zero net energy” building approach. This precast concrete building integrates its design with its surrounding landscape, utilizing on‐site renewable energy resources and minimizing resource consumption to achieve its \"zero net energy\" goal.

SITE/BUILDING PLACEMENT The placement of the LRC follows the shape of the creak. Allowing it to have easier access to the resources provided by the creek, namely cool running water and its current. Due to the winds being blocked by the hills on the East and West, the building relies on the sea and the land breeze coming from the North and the South respectively. The building is therefore angled by 120 degrees, allowing it to maximize airflow. ZONING: Level 1: (Lower Secondary) Level 2: (Upper Secondary)

WINDOW PLACEMENT/ORIENTATION Wooden louvers and wooden carved windows These windows are placed on all sides on all of the LRC’s exterior walls, this is due to hills beside the building causing the airflow from the sea and a land breeze to tunnel through the opening of the hills, which is where the building is at. The windows are aligned and placed on walls directly facing one another. This allows the wind to directly flow through the building and cool it down at a faster rate. GREEN MATERIALS CONCRETE PRECAST RECYCLED WOOD RECYCLED PALLETS

ENERGY SAVING SYSTEMS SOLAR PANELS Due to the sun being in direct contact with the LRC for most of the daylight hours, Solar Panels are placed on the roof of the LRC to harness energy from the sun’s direct sunlight. GREEN/LIVING ROOF & ROOFTOP GARDEN Green/Living Roof & Rooftop GardenThe LRC has a green roof that allows the direct sunlight during the daylight hours to be absorbed by the plants which act as a buffer, allowing for the reduction of heat absorption while creating a cleaner environment. It also helps reduce the glare from the solar panels reflecting on the skylights by acting as a partition for the two. The green roof also has a rooftop garden that allows students to learn more about nature and their environment. SKYLIGHTS Skylights allow light to pass through and illuminate the rooms without relying on artificial lighting during daylight hours. The glass used on the skylights is from the Pella® Impervia® Series. These glass windows are equipped with two panes of glass with SunDefense Low-E protection and insulating argon between the panes. Blocking out  94% of the sun’s ultraviolet rays and heat while allowing in visible light and providing a clear view. Thus allowing the level 2 rooms to be lit up via natural lighting throughout the daylight hours without having to deal with the immense heat, glare, and UV rays.

CIRCULATION: The LRC is vertically zoned, with the Lower Secondary students filling up level 1 while the Upper Secondary students fill up level 2. The two levels are connected via the amphitheater and the library through the amphitheater's stairs which also acts as seating for the amphitheater. All rooms on the same level are connected via the corridor. The LRC is also able to utilise this corridor on level 2 to connect to the preexisting building VENTILATION DOUBLE ENVELOPE The double envelope uses a mixture of wooden carved windows and transparent louvers. The outer facade helps reduce the amount of direct sunlight shown into the corridor, reducing the direct heat gain. The buffer space between the 2 facades acts as insulation against extreme temperatures, winds, and sound, improving the building's thermal efficiency for both high and low temperatures. The corridor also has a mini elongated garden to reduce the heat gain as well as help improve indoor air quality. UNIQUE ROOF AND COOLING TOWER Through its unique half- raised pointed roof and cooling towers, it helps increases the airflow acceleration to eliminate heat accumulation by allowing air to rise up and out through the top of the roof, allowing the hot air from the rooms to be quickly carried out and expelled to the surroundings.
