SITING, ORIENTATION AND SHADING COMPREHENSIVE SITING AND ORIENTATION STUDIES TO OPTIMIZE THERMAL PERFORMANCE AND SHADING OF THE BUILDING ENVELOPE TO REDUCE ENERGY CONSUMPTION BY A TARGET OF 25%.
SITING, ORIENTATION AND SHADING Comprehensive ENERGY MODELLING orientation studies to optimize thermal control and reduce energy consumption, with a target of 25% reduction
WALL CONSTRUCTION
SITING, ORIENTATION AND SHADING DETAILED SHADING STUDIES TO PREVENT DIRECT INCIDENCE OF SUN INTO THE LEARNING AREAS, TO PREVENT HEAT GAIN AND REDUCE GLARE, TO IMPROVE STUDENT COMFORT AND CONCENTRATION.

SITING, ORIENTATION AND SHADING
SHADING OF NON-ROOF SURFACES USE OF SHADE INCORPORATED WITHIN LANDSCAPE DESIGN TO REDUCE SOLAR IMPACT ON STUDENTS AND THE ENVIRONMENTAL FABRIC. HEAT ISLAND EFFECT
SHADING OF NON-ROOF SURFACES THROUGH LANDSCAPING AND MATURE TREES AND SOFTSCAPE SELECTED SPECIALLY TO USE LESS WATER
SHADING OF NON-ROOF SURFACES SHADED DROP OFF AREA AND WALKWAYS TO PROVIDE OUTDOOR THERMAL COMFORT AND PROTECTION, MAKING THE TRANSITION TO THE SCHOOL MORE INVITING AND PLEASANT. EXTERNAL SHADE STRUCTURES TO SHADE HORIZONTAL AND VERTICAL SURFACES HAVING A MINIMUM S.R.I. OF 29. SHADED OUTSIDE LEARNING AREAS TO BE USED IN THE GOOD MONTHS PROVIDING A VARIETY OF LEARNING ENVIRONMENTS, GETTING STUDENTS CLOSER TO NATURE AND OUTDOOR LIVING
SHADING OF NON-ROOF SURFACES PV PANELS, ECO TREE AND THE BUILDING ITSELF PROVIDES SHADING OF EDUCATIONAL SPACES. THE LIVING WALL PROVIDES SHADING OF THE WALLS, THEREBY REDUCING ENERGY NEEDS AS WELL AS INCREASE THE MOISTURE IN THE COURTYARD INCREASING COMFORT.
HVAC ENERGY CONSERVATION HVAC SYSTEMS HAVE BEEN DESIGNED TO MAXIMIZE ENERGY PERFORMANCE. HEAT RECOVERY FACILITIES SUCH AS HEAT EXCHANGERS HAVE BEEN INCORPORATED IN EXTRACT/SUPPLY AIR SYSTEMS TO ENSURE THAT THE MAXIMUM AVAILABLE ENERGY IS RECOVERED FOR TEMPERING THE INCOMING AMBIENT AIR. A COMPREHENSIVE BUILDING ENERGY MANAGEMENT SYSTEM IS EMPLOYED IN ORDER TO PROVIDE CENTRAL CONTROL, MONITORING AND MANAGEMENT OF ENERGY USAGE FOR THE COMPLETE BUILDING SERVICES.
HVAC ENERGY CONSERVATION ALL DUCTWORK AND PIPEWORK IS WELL INSULATED TO ASHRAE STANDARD 90.1.2007 IN ORDER TO MINIMIZE ENERGY LOSSES AND MAXIMIZE POTENTIAL ENERGY RECOVERY.
PHOTOVOLTAIC PANELS GRID CONNECTED PHOTOVOLTAIC PANELS PROVIDE BETWEEN 7-9% OF TOTAL LOAD OF THE SCHOOLS IN ON-SITE RENEWABLE ENERGY
SOLAR THERMAL WATER HEATING SOLAR HOT WATER HEATING SYSTEM IS USED AS AN ON-SITE RENEWABLE ENERGY SOURCE TO PROVIDE DOMESTIC HOT WATER FOR SHOWERS AND SWIMMING POOL
MATERIALS AND INDOOR ENVIROMENTAL QUALITY: USE OF RECYCLED, RECYCLABLE MATERIALS. USE OF MATERIALS PROCURED WITHIN 500 KM. NO VOC MATERIALS. CONSTRUCTION FLUSH OUT FOR IMPROVED INDOOR ENVIRONMENT MATERIALS AND INTERIOR ENVIRONMENTAL QUALITY
DAYLIGHT AND VIEWS HIGH PERFORMANCE WINDOWS AND GLAZING WITH PROPER, WELL ANALYZED SHADES AND CONTROLLED LIGHTING TO PROVIDE IMPROVED CONCENTRATION, MORE FRIENDLY ENVIRONMENT AND ENERGY SAVINGS.
DAYLIGHT AND VIEWS HIGH WINDOWS LOW-HIGH WINDOWS
DAYLIGHT AND VIEWS LIGHT TUBES PROVIDE AMBIENT NATURAL DAYLIGHT FOR INTERIOR, DIFFICULT TO HAVE WINDOWS SPACES. THESE ARE REALLY USEFUL TOOLS FOR SPACES WHERE VIEWS TO OUTDOORS ARE NOT THAT IMPORTANT.
DAYLIGHT AND VIEWS LIGHT TUBES
LIGHTING AND VENTILATION CONTROLS DAYLIGHTING CONTROLS TO PROVIDE ENERGY SAVINGS AS WELL AS GOOD QUALITY LIGHTING WHILE CARBON DIOXIDE MONITORS PROVIDE BETTER AIR FOR IMPROVED CONCENTRATION, MORE FRIENDLY ENVIRONMENT.
LIGHTING NATURAL AND ARTIFICIAL HIGH EFFICIENCY LUMINAIRES COMPLETE WITH LOW WATTAGE LAMPS AND HIGH FREQUENCY CONTROL GEAR HAVE BEEN INCORPORATED TO OPTIMIZE LIGHT OUTPUT AND REDUCE SWITCHING LOSSES. HIGH EFFICIENCY REFLECTORS HAVE ALSO BEEN INCORPORATED WITHIN LUMINAIRES WHERE PRACTICAL IN ORDER TO OPTIMIZE THE LIGHT OUTPUT LOW ENERGY LONG LIFE LIGHTING SOURCES SUCH AS FLOURESCENT, COMPACT FLOURESCENT AND LED HAVE BEEN INCORPORATED THROUGHOUT
WATER CONSERVATION GOAL OF 20% WATER SENSITIVE LANDSCAPING USING NATIVE AND/OR ADAPTIVE SPECIES TO REDUCE WATER USEAGE CAREFUL PLANT SELECTION, USE OF ARTIFICIAL TURF FOR FIELDS AND BALANCING OF HARD AND SOFT LANDSCAPED AREAS.
WATER CONSERVATION LOW FLOW FIXTURES: REDUCTION IN POTABLE WATER USEAGE: REDUCTION OF DOMESTIC WATER CONSUMPTION THROUGHT UTILIZATION OF LOW FLUSH AND LOW FLOW FIXTURE UNITS. CONDENSATE RECOVERY FROM THE AIR CONDITIONING SYSTEM IS REUSED FOR IRRIGATION THEREBY REDUCING WATER USEAGE. FIRE FIGHTING SYSTEM WATER: THE REGULARLY REQUIRED TESTING OF THE FIRE FIGHTING SYSTEM USES WATER THAT IS CHANNELLED TO THE CONDENSATE RECOVERY TANK AND REUSED AS WELL.
INDOOR NOISE POLLUTION REDUCTION COMPREHENSIVE ACCOUSTICAL STUDIES OF LEARNING AREAS TO ENSURE THAT THE INDOOR ENVIROMENT IS HEALTHY, CONDUCIVE TO LEARNING, NOT DISTRACTING AND APPROPRIATE FOR THE USE. Surface finishes in classroom: a. Rear wall - sound absorbing or diffusing b. Ceiling - sound reflective (eg plasterboard) c. Floor - sound absorbing (eg carpet) d. Walls - sound reflective e. Ceiling - sound absorbing Corridor, Stair case Toilets /showers Music room Office, speech therapy, clinic, conference rooms Outdoor Classrooms 45 60 50 50 60 Corridors 45 60 45 45 55 Music rooms 60 60 60 45 60 Office, speech therapy, clinic, conference rooms 45 60 45 45 60 Mechanical Equipment room cafeteria, Gym or pool
BUILDING AS TEACHING TOOL ECO-COURTYARD WITH LIVING WALL AND ECO-TREE TO PROVIDE DAYLIGHT AND VENTILATION PLUS ADDITIONAL BENEFIT OF SUSTAINABILITY EDUCATION TO CREAT STUDENT INTEREST IN SCIENCE AND MATHS. LOCATED OFF THE SCIENCE/ART MULTIPURPOSE LABS. SHADED BY PHOTO-VOLTAICS.
BUILDING AS TEACHING TOOL THE BUILDING MANAGEMENT SYSTEM WHICH MANAGES THE BUILDING SERVICES AND TRACKS ENERGY USEAGE WILL BE HOOKED UP TO THE EDUCATIONAL NETWORK TO HELP STUDENTS TRACK BUILDING PERFORMANCE AND LEARN ABOUT THE ENVIRONMENTAL ISSUES
COMMUNITY USE AND SHARING DESIGN ALLOWS FOR EASY USE BY THE COMMUNITY IN OFF HOURS OF CERTAIN SPACES LIKE: AUDITORIUM SWIMMING POOL GYMNASIUM LIBRARY DINING SPACE MULTI-USE SPACE DINING ROOM DOUBLES UP AS PRE-FUNCTION
CONSTRUCTION RATING COMPLETED ON ONE PROJECT: CLOSE COOPERATION WITH UPC ESTIDAMA TEAM IMPORTANT FOR THE CONSTRUCTION TEAM TO BE INTEGRATED AND CONCIOUS OF THE ISSUES THROUGHOUT IMPORTANT TO DISCUSS IN PRE-CONSTRUCTION MEETING REGULAR TRACKING AND FOLLOW-UP IS IMPORTANT IMPORTANT FOR EVERYONE ON THE SITE BEING AWARE OF THE ISSUES GOOD COMMISSIONING PROCESS IS VERY IMPORTANT NO POINT GOING THROUGH ALL THIS TROUBLE AND THEN NOT MAKE SURE IT GETS DONE
THANK YOU VERY MUCH QUESTIONS?
