We live in an era where we are rushed against time to manage our ever-growing energy demands and are required to devise strategies that aid in smart utilization of all energy sources. Bringing into focus energy conservation with this would help address several issues such as energy costs, air pollution, greenhouse gases, global climate change, and our dependence on non-renewable sources of energy. Therefore, it becomes vital to seek alternative solutions to meet surmounting energy demands rather than the mere application of conventional systems in design and planning. 

Through this project, we seek to understand the role that location, environment, and climate have on design and how we can integrate design with sustainable building systems to achieve energy-efficient buildings. This will be achieved through a series of exercises in modeling, simulations, and data analysis thereafter. Simultaneous precedent studies would further assist in the understanding of various systems and strategies currently used in similar climatic conditions and assist in choosing the most efficient solution for our project type.

DAYLIGHTING ANALYSIS

Daylighting Goals:

1. Informed design decisions through climate study
2. Incorporate measures to control Annual solar glare
3. Promote well being and health through the provision of continuous daylight.

Objective- To design a school wing in the given site by maximizing the provision of north light for reading spaces and achieve LEED v.4 criteria of 50% Spatial Daylight Autonomy (SDA) at 300 lux annually, and Annual solar exposure (ASE) of no more than 10% using passive lighting & shading design strategies.
 

Assumptions:
-Occupied hours were considered as 8 am-6 pm. 
-The work plane was considered at a height of .76m and the spacing is at 6m c/c. 
-The Eye-level is considered at 1.2m for Annual Glare.
-All simulations are run for Sept 23rd at 24:00hrs

ELECTRIC LIGHTING ANALYSIS

Daylighting Goals:

1. Reduced Liighting power density
2. Controlled lighting to maximize efficiency
3. Use of energy efficient luminaires.

Objective - Achieve an efficient lighting scheme using a combination of 2 or 3 lights that provides maximum efficiency with desired illuminance and adheres to the lighting power density of 12.9W/m2  for a school program type.
The toilet is set to a baseline illuminance level of 300lux while the other spaces require a work plane illuminance of 500lux.

 

Assumptions:

-Occupied hours were considered as 8 am-6pm. 
-The work plane was considered at a height of .76m and the spacing is at 6m c/c. 
-The Eye -level is considered at 1.2m for Annual Glare.
-All simulations are run for Sept 23rd at 24:00hrs

HVAC CONCEPTS

HVAC Goals:

1. Strive for thermal comfort throughout the year.
2. Reduction of energy demands for heating and cooling through passive design strategies for efficient building envelope like fenestrations (louvers, overhangs, double glazed windows, etc)
3.Understand how to reduce ventilation energy demands in the given climatic conditions.
4. Seek an integrated design that couples HVAC to the energy required for water heating.

WATER EFFICIENCY CONCEPTS

Water Efficiency Goals:

1. Curb wasteful disposal of water that can be reused. Conservation to reduce water demand.
2. Storm water management and ways to store, clean, and reuse water for irrigation and non-potable purposes.
3. Minimize water consumption in toilets and outdoor spaces.
4. Bio re-use of waste for landscaping.

DESIGN SUMMARY

The overall integration of all these systems seeks to reduce energy usage intensity (EUI) across its building. Research shows that a projected saving of 2-3% over the first year in reference to a baseline year is a good estimate.
Quantifiable benefits of such an approach would be lower energy and maintenance costs, reduced pollution, slower global warming, and better energy reliability. The qualitative benefits that are hard to measure would include healthier well-being, increased student productivity, and security in the knowledge of assured energy supply.
