Concepts and Design Ideas Assalamualaikum waroh matullahi wabarakatuh Concepts and Design Ideas Noor Hanita Abdul Majid Ecological Sustainable Design AAR 4092

Minimize energy consumption Maximize on-site renewable energy production Use energy efficiently Other local reduction methods Additional renewable Carbon zero Conventional design INSTRUMENTS: education, incentives, grants, regulations, benchmarking, planning policy, energy policy, green building rating

Green building items -passive design Topographic responsiveness Building form-orientation Shading devices BiPV-harnessing solar energy Low E-glazing-increase ee with reduction of solar radiation Vertical greenery on façade Green roof Natural ventilation Solar chimney ducts-buoyancy effect to induce natural ventilation Light shelf Green building items -passive design

Environmental design strategies High performance envelope-PV, insulated walls, double skin facades, laminated and screen patterns Exposed thermal mass Daylight and solar control Natural ventilation BAS-motion and daylight sensors Environmental design strategies

ESD

ESD for energy efficiency Alternate circuit and timer Light zoning Task lighting at work stations Energy efficient lifts Shading devices Double roofs Cool paints Light shelves West facing building services as buffer Identify possibilities of naturally ventilated spaces ESD for energy efficiency

ESD for water efficiency Sensor operated water taps Sensor operated automatic flushing system Rainwater harvesting system-landscape irrigation/drip irrigation system Provisions to use newater Use of greywater (from i.e. handwash basin and showers) to flush WC Use of aerated showers ESD for water efficiency

ESD for environmental air quality Low VOC paints, carpets and furniture Refrigerant leak detection system Mould and fungi eliminating liquid compound Plants at work place ESD for environmental air quality

Bamboo house Occupant well being-thermal comfort Visual comfort Air quality Thermal mass Light shelves Natural ventilation Choice of material Operational energy-energy demand Bamboo house

Occupant well being-thermal comfort Thermal comfort ranges for different people Preferred temperature can be plotted to determine the thermal range of comfort Occupant well being-thermal comfort

Visual comfort General guidelines 100 lux: corridors 300 lux: reading 2000 lux: computers Visual comfort

Naturally ventilated areas showed low readings of CO2-limit 1000ppm Air quality

As a buffer to the swings in air temperature-moderates the differences It keeps the house cool during the day but slightly warm the house at night time Thermal mass

East and west facing openings will only get reflected direct lights from 10-30 degrees from horizontal=before 0900 and after 1700 Only diffused light will enter during the middle part of the day and windows on the north and south side Light shelves

Local topography, vegetation and surrounding buildings have an effect on the wind speed and directions-critical factor in the effective operation for natural ventilation Natural ventilation

Choice of material Operational energy-energy demand Bamboo-readily available, fast growing minimal environmental impact Choice of material Operational energy-energy demand

United Christian College

High connectivity and interaction of indoor and outdoor spaces (eco-path, communal courtyards, outdoor classroom, green roof, atrium green wall) Low carbon environment-facilitating and utilization of natural ventilation

Grey water from swimming pool for cleansing of outdoor paved areas Composting bin at the ecopath to turn waste into fertilizer Green terraces to reduce heat gain and improve the air quality No or low VOC finishing materials in the indoor applications

Passive cooling to reduce carbon footprint Atriums with top vents for stack effect Cross ventilation enhanced by wind catcher and wing walls Maximise the use of daylighting

Council House 2 (CH2)

Sustainable design and energy performance POE result-rated highly in thermal comfort, daylighting and air quality Personal control at workstations

Passive design techniques- duration of opening and displacement of air Concrete ceiling absorbs heat during the day and release heat at night Sunshading to minimize heat gain and filter light penetration

Green slope-3rd prize winner

Filtered treated and stored Hot water warmed by solar Biological treatment Inflow-overflow Combined greywater and rainwater utilization system with underground tanks Water recycling-water from green roof and lake+ underground water pumped through a well Filtered treated and stored Hot water warmed by solar Secondary water recycling-rainwater + runoff stored in greywater tank for treatment Used for flushing toilets and watering greens

The given climatic conditions

Solar panels for glazing and energy generation Passive solar design aimed to maintain interior thermal comfort and reduce requirements for active heating and cooling-turbines, cross ventilatilation, shading, jalousie on exterior walls, ventilated green atrium space( refreshing the air and reducing noise)

examples

Green creepers on the east-west façade shading the interior spaces from direct sunlight Integrated filtering system for treatment of greywater, blackwater and stormwater Living machine to produce portable water-wastewater treatment technology-series of tanks+ vegetation + organisms= bioremediation and ecological based components
