Building Design has become very complex and National Building Code 2005 recommends that there should be an integrated approach for the design from the very beginning. This has to be achieved by team work, with the team consisting of the Architect, Structural and Services (Electrical, Mechanical, Air-conditioning, Plumbing, Sanitary) engineers.

    • Integrated Approach to Design, Construction & Commissioning of Buildings
      • AND ENERGY EFFICIENT DESIGNS:
      • A PROSPEROUS PATH TO A CLEAN ENVIRONMENT
    • Introduction
      • Building Configuration and Placement
      • Design Tools
      • Passive Solar (includes passive solar heating, passive solar cooling, thermal storage, daylighting)
      • Building Envelope
      • Active Solar and Photovoltaic Systems
      • Appliances & Equipment
      • Lighting
      • Building Materials
    • Introduction
      • Establishing a base case—for example, a performance profile showing energy use and costs for a typical facility that complies with code and other measures for the project type, location, size, etc.
      • Identifying a range of solutions—all those that appear to have potential for the specific project.
      • Evaluating the performance of individual strategies—one by one through sensitivity analysis or a process of elimination parametrics
      • Grouping strategies that are high performers into different combinations to evaluate performance.
      • Selecting strategies, refining the design, and reiterating the analysis throughout the process.
      • design teams often make incremental changes that are effective and result in high-performance buildings.
        • Building Configuration and Placement
        • Solar accessibility should be a part of site analysis.
        • Orienting the building
        • "skin to volume" ratio of the building
        • perimeter daylighting
        • Compromise the thermal performance of the building, the electrical load and cooling load savings
    • Design and Analysis Tools for Building Simulation ?
      • Building Design Advisor
      • Building life-cycle cost Assessment
      • DOE-2 hour-by-hour energy use
      • ENERGY-10 annual simulation program
      • Energy Plus modeling buildings with associated heating, cooling, lighting, ventilating, and other energy flows
      • SERI-RES passive solar design and thermal performance
      • SPARK Models complex building envelopes
      • Window thermal performance of fenestration products
    • Passive Solar Design
      • Passive Solar Heating
      • Passive Solar Cooling
      • Thermal Storage
      • Daylighting
    • Passive solar design - challenging
      • Can natural daylighting reduce the need for electric light?
      • If less electric light generates less heat, will there be a lower cooling load?
      • If the cooling load is lower, can the fans be smaller?
      • Will natural ventilation allow fans and other cooling equipment to be turned off at times ?
      • Climate (sun, wind, air temperature, and humidity)
      • Building orientation (glazing and room layout)
      • Building use type (occupancy schedules and use profiles)
      • Lighting and daylighting (electric and natural light sources)
      • Building envelope (geometry, insulation, fenestration, air leakage, ventilation, shading, thermal mass, color)
      • Internal heat gains (from lighting, office equipment, machinery, and people)
      • HVAC (plant, systems, and controls)
      • Energy costs (fuel source, demand charges, conversion efficiency).
    • The Problem
      • an optimum design is based on minimizing life-cycle cost : the sum of solar system first-cost and life-cycle operating costs
      • 19 th century contrivances that seemed to serve our parents and grandparents so well are attracting our attention today.
      • Cost and technical analyses
    • Building Envelope
      • Windows
      • Walls and Roofs
      • Insulation
      • Climate Considerations
      • Doors, Windows, and Openings
      • Thermal Efficiency
      • Reflectivity
      • Moisture Buildup
    • Active Solar Systems
      • Active Solar Hot Water
      • Active Solar Heating
      • Photovoltaic Cells
      • Biomass Generation
      • Recycling Building waste
      • Wind Energy?
    • TECHNOLOGY AVAILABLE
      • Advanced Wind Turbines.
      • Photovoltaic Modules.
        • Economically viable for high quality power applications.
      • Rail Transport in preference to Road.
      • Telecomunications, Data & Video communications & Electronic Commerce. -----Travel less.
    •  
    • Some examples of Innovative path
      • Battery Bus
      • Zero effluent - Zuari fertiliser.
      • Energy efficiency - Ambuja Cement.
      • Use office waste for heat & energy.
      • Use CNG in preference to liquid fuels.
      • Reduce pollution at traffic lights.
    • Some Steps of Innovative path
      • Buildings to be designed to be reasonably self sufficient to operate; with their own energy sources & waste disposal systems.
      • Industrial units to have their basic power generation locally.
      • Use electronic communications; Minimise TRAVEL
    • Results of Innovative path
      • Energy consumpion should marginally decrease & there should be a change from OIL, COAL & Nuclear to SOLAR, WIND & Fuel Cells.
      • Sustainable Building Materials
      • Non-toxic
      • Recycled and recyclable
      • Renewable
      • Local
      • Standard sizes, modular, pre-cut (reduces waste)

      • HVAC
      • Lighting
      • Water Supply & Sewage Disposal
      • Fire Detection & Protection
