Avoid Heat island effect- Lower building mass towards the cities edge than the center- Avoid large high rise clusters- Vegetating urban landscapes improves community life and air quality by reducing summer temperatures and air conditioningBenefits of green belts- Improves air quality within urban areas (air corridors)- Encourages walking & biking- Habitat for wild plants and wildlifeDesign unsealed surfaces - Open joint pavements for walkways allows the surface to breathe and provide cooling effectDesign shaded surfaces to avoid heat build up- Evaporation in hot climates lasts longer - Trees: shading, noise reduction, filters dust, reduces CO2 while oxygen is produced Green roofs and green facades- Delays storm water reach the drainage and avoid rapid flooding- Reduces energy losses in cold climate & heat build up in hot.- Reduce street noise- Provides extra living space- Enhances biodiversity and wildlifePassive solar energy and solar performance - Full advantage of the sun's natural heat. With good orientation, the building will capture solar heat in winter & block solar gain in summer. Natural Ventilation and Air movement - Helps cool occupants by increasing air movement - Position of faade openings to enhance natural ventilation.- Use of solar chimneys to enhance stack air movement- Don't install 1 cooling unit only. Use add-on systems mechanical ventilation with top cooling beams at the facade Wind - Renewable energy, can reduce greenhouse gas emissions - The long axis of building should be parallel to wind flow.- Tall buildings to step away from the wind- Curved facades moderate the impact of wind. Use canopies & podiums to reduce down draft.- Building layout should avoid tunneling effect between two adjacent buildings.Floors and Ceilings Cooling strategies- Floor undersides can determine effective thermal mass. Concrete floor free of finishes radiates stored heat in cold conditions & coolsin hot conditions.- Cooled raised floors (embed pipes to carry cooling water)- Thermo active Slabs : Water-filled embedded in concrete floor aid cooling/heating energy into the interiors of the building regulating temperatures.- Chilled Ceilings reduce thermal stratification andbalances the effect of thermal buoyancy rising warm air.Lighting Design- Maximize day lighting for visual comfort, productivity and reduce energy use (electricity savings and lower lighting levels)- Automatic/Timedlightcontrol system switches the lights off or dims them to a lower level. - Specify energy efficient lamps. (low wattage lamps produce less heat which in return does not need to be cooled expensively.)PrincipalDay Lighting Design Factors- Orientation of windows (provide external daylight and time orientation for occupants- Reflection surrounding surfaces- Glazing has a clear influence on daylight % but large windows also provide heat gain and loss- Skylights assist natural lighting- In non-domestic buildings, window area should be 20 % of floor area to provide sufficient light to a depth of 1.5 times the height of the room.Benoy Case study: J iang Tai Project, BeijingBenoys Role : A commitment to Sustainable DesignBenoy isthe lead consultant providing a full scope of professional service from initial planning to retail and hotel interior design. The project is currently under construction with an aim to open by 2011. Benoy and the Developer committed in ensuring that the project buildings are planned, designed, constructed and managed with respect to the environment and should receive Gold LEED and excellent HK-BEAM standing (Hong Kong Building Environmental Assessment Method) systems.Developers: Hong Kong Swire Properties & Beijing Sino Ocean LandLead Architect, Hotel and Retail Interior Design: BenoyStructural and MEP Engineers: Ove Arup (Hong Kong) Faade Consultant: Hugh Dutton Associates (Paris)Faade Engineers: ARUP Faade (Hong Kong) Landscape Architect: Urbis Limited Acoustic Consultant: ARUP Acoustics Daylight and Energy Simulation Building Energy Research Centre:Tsinghua UniversityLocation: Chaoyang District, BeijingSite area: 58,628mTotal GFA: 175,885.05mHeight limit: 100mGreen Area Ratio: 20%Site Coverage: 53.75%3 major components:- 4 levels (& 3 basements), 84,496mRetail Podiumwith 154 shops, 6 house cineplex, 500 capacity food court & winter garden space covered by a complex monocoque structure.- 24 floors square Office Tower.- 24 floors Hotel (370 rooms) Typical plan using shallow floor plates with most rooms facing the open park in the east.Retail podium Hotel OfficeMaximizing open space potential with native plant speciesSite Design StrategiesLocated in a medium density mix used area, the projects intention is to compliment the large public park east of the site. Seeing this as an opportunity, Benoys site design strategies aim to:- Create a level of development density that is in congruity with the surrounding area.- Enable linkage to the park. - Provide daylight opportunities to office tower and retail podium.- Reduce surface exposure with compact massing relationship. - Optimize quantity and quality of open space on site- Maximize urban connectivity, locate entrances near bus stops for pedestrian convenience and provide 200m bicycle storage to encourage use of bicycle- Maximizes open space on G/F with all basement car parking- Adapted Landscape planting to enhance local ecology.Heat island effect reduction (tree shading, low solar reflectance materials & open grid pavers.Water Resource StrategiesDue to recent rapid urbanization, Beijing is constantly facing a shortage of water supply. The J iang Tai Project aims to minimize water usage and recover all potential re-useable water. - Development of water resource management plan (integrated rainwater collection and grey water recovery system). - Five underground concrete rainwater collection pools to receive storm runoff (recovered water will be mainly used for flushing and landscape irrigation). - 30% reduction of potable water by selecting low flow water closets, urinals, showers and sinks.Integrated water recovery room, 675m2 plant room on B1, 6m clear headroom5 rainwater collection tanksCondensation water180m3Rain/condensation water Treatment Tank180m3grey water Treatment Tank80m3Recovered water tank 2 hour usage capacityGrey waterTreatment processTreatment processIntegrated water recovery schematic flow diagramEnergy ConservationBeijing has recently implemented new energy saving requirements for public buildings. The Project satisfies these requirements and commits to provide energy saving/recovery mechanisms. Basic Envelope Design PrinciplesThe roof and wall surface of each building component is restricted to 30% glass to solid ratio.- All low E glass specified (min. thermal transmittance value and Insulated Glass Unit (IGU) - Winter Garden: Monocoque roof with fritted patterns provides shading to large event space andreduces summer cooling load. 60% of arcade have natural light. - Sun-shading mechanism is under-consideration to provide flexibility for sunlight control.- 10,625m of green roof to provide thermal protection to retail podium & create a visual and sustainable design statement. All glass including the monocoque roof will use Low-E IGUInterior of Winter Garden space with sun shading deviceEnergy Conservation- 78 ice storage devices produce ice at night for thermal exchange during daytime. The aim is to take advantage of lower electrical cost at night while transferring the peak electrical loading to nighttime, reducing day time power production demands.- Maximize Energy Efficiency - Heat recovery device are installed to capture residual heat energy from return air duct, maximizing energy efficiency. - Simulate energy usage during the design stage- Use of Building Management System to monitor on-going energy usage and consumption.- Use of low energy consumption light fitting like LEDs.- Eliminate landscape & faade decorative lighting, control light density and intensity- Provide exterior lights for way-finding, safety andsecurity only.- Use only of R-22 or R134a refrigerants to minimize ozone depletion.Ice storage tank for Air Conditioning, reference from EMSD Hong Kong28m deep atrium allowing sunlight deep penetration of daylight into the basement retail spaceMaterial and Resource Management- Provision of 630m of material recovery, sorting and storage space for recyclables located near the loading bays.- With 20% lettable area, large amounts of organic waste will be generated daily, the project is considering an advanced bio-organic waste management machine that convert kitchen waste to nutrient rich water for safe discharge or irrigation.- Use of environmental materials (regionally manufactured to reduce transportation costs and pollution generated during material delivery) :* Engineered bamboo(floors, wall panels,handrail, etc.)* Certified wood(handrails, etc.)* Steel structure with highrecycle steel contentFlooring mainly of constituted stone and engineered bambooUse of bamboo as decorative panelsIndoor Environmental Quality- Establish minimal air quality performanceby enhancing and controlling outdoor air flow capacity(LEED requirement).- Prohibit indoor smoking, (designated smoking areas).- Increase indoor ventilation rate by 30% above ASHRAE62.1-2004 standards- Require contractor to do air quality plan during construction stage to prevent pollution- Specify low VOC emitting materials, such as:* Carpet and carpet cushion* Sealant, adhesive* Paints, sealers, coatings* Composite wood productsKey Points SummaryAfter the completion, the project will obtain ISO 14001, Environmental Management Standard to help minimize its environmental impact during the operational stage and will achieve LEED accreditation.Public transport connection commercial/ communityvalueAllocated underground parking reduction of noise and pollutionGreen space and reduce heat island effectgreen ratio apply per plan codeMaximum open spacesame with most planning rulesLight pollutionbenefits to running costWater efficiencybenefits to running costIndoor environmental qualitybenefits to leasing opportunitiesOptimized Energy Performancebenefits to running costInnovation and design processpublic education is counted benefiting to business imagesPotential Energy ReductionsTenantHVAC 10-40% designcontrolscommissioningLighting25-50% fittingscontrolsPower 10-25% fixturesAVcontrolsBenoy Case study: Hyderabad Botanical GardenOffice Area 3Office Area 2Nursery SupermarketEntrance PlazaRetailBotanical Gardens Mixed use Project at a glanceBenoys design scope :- 75,000m2 high-street mall (with 8-screen multiplex, various anchors & hypermarket)-14,000m2 office development & supporting uses such as a grand entrance plaza (1,800m2) & a nursery supermarket garden centre(2,000m2)Client : Delara Tourism Corporation LtdSpecial focus is on sustainability and low energy consumption throughout the design.
