A) Building Energy Efficiency

Energy efficiency is the process of reducing amount of energy required to provide various products and services. DPU has taken initiative in building energy efficiency domain by installing brushless direct current fans, heat pumps, LED lamps, electric vehicles for patient transfer and has built up electronic vehicle charging station. DPU also has taken pioneering step in energy conservation by installing LED lamps with sustainability label of energy star at various areas in the campus. This ensures sustainable consumption of energy.

Installation of BLDC (Brushless Direct Current)

DPU has replaced old traditional AC copper winding fans with new generation BLDC fans. Till Date 5200 fans are installed. Technical details and features of BLDC fans over Winding fans are as follows. A BLDC fan refers to a Brushless Direct Current fan, which uses a brushless DC motor to operate. These motors differ from traditional AC (Alternating Current) or brushed DC motors in several key ways.

Key Features of BLDC Fans

1. Energy Efficiency: BLDC motors are more efficient than traditional motors because they minimize power losses. They typically save 40-70% more electricity than conventional ceiling fans.
2. No Brushes: Unlike conventional DC motors that use brushes to transfer electrical current to the rotor, BLDC motors use electronic commutation, which eliminates friction and wear, making them more durable and maintenance-free.
3. Quieter Operation: BLDC fans are quieter than traditional fans because they have fewer mechanical components that can generate noise.
4. Speed Control: These fans offer better control over speed and can be easily adjusted electronically without the humming noise that conventional fans may produce at lower speeds.
5. Long Lifespan: Since there is less friction due to the absence of brushes, BLDC motors tend to have a longer operational life.

Remote Control: Many BLDC fans come with smart features, including remote control or integration with smart home systems, allowing for ease of use and energy savings.

Comparison in terms of power consumption and efficiency

1. Power Consumption:

• Winding (AC Induction) Fan:

  A typical ceiling fan with an AC induction motor consumes 70-80 watts of power at its highest speed.

• BLDC Fan:

  A BLDC fan consumes significantly less, usually between 25-35 watts at its highest speed.

2. Energy Savings:

• BLDC Fan:

  On average, a BLDC fan can save 40-70% of energy compared to a traditional winding fan. For example, if a standard fan uses 75 watts, a comparable BLDC fan might only use 28 watts for the same airflow and speed.

3. Yearly Power Consumption:

Assuming an average usage of 8 hours per day for a year:

• AC Induction Fan:

  Power Consumption = 75W × 8 hours/day × 365 days ≈ 219 kWh/year

• BLDC Fan:

  Power Consumption = 28W × 8 hours/day × 365 days ≈ 81.8 kWh/year

Features Summary (All calculations are average)

Heat Pump System: (Combined heat and Power)

DPU has installed Heat Pump system and replaced traditional Electric Geysers. 2 Heat pumps are installed at hostel premises. The capacity of heat pumps are 529 Litres per hour. The heat pumps are installed at boys and girls hostel respectively.

Technical Information are as follows:

A heat pump is a device that transfers heat energy from one place to another, typically using electricity. It can work for both heating and cooling purposes, making it an efficient and versatile system for climate control in homes and buildings. Heat pumps are widely used because they are highly energy-efficient compared to conventional heating and cooling methods.

Efficiency and Benefits:

• Energy Efficiency: Heat pumps are highly energy-efficient, as they transfer heat instead of generating it. Their Coefficient of Performance (COP) can be 3 to 4, meaning for every unit of electricity used, they provide 3-4 units of heating or cooling energy.
• Lower Operational Costs: Because they transfer heat instead of creating it, they are often cheaper to run than traditional systems like electric resistance heaters or gas furnaces.
• Eco-friendly: Heat pumps use less energy and can reduce carbon emissions, especially when powered by renewable electricity.
• Dual Function: A heat pump provides both heating and cooling, making it an all-in-one solution for year-round climate control.

3) A Summary of Energy Conservation:

D) Sustainable Water Extraction Technology

Sustainable water extraction technologies aim to meet current water demands without compromising the ability of future generations to access clean water. These technologies focus on efficient, low-impact methods of extracting water from natural sources while minimizing environmental and resource degradation.

Rain Water Harvesting:

Rainwater harvesting (RWH) is the process of collecting and storing rainwater for future use, particularly in regions where water scarcity is an issue or where there's a need to reduce dependency on traditional water sources like rivers or groundwater. This method is considered sustainable, low-cost, and eco-friendly.

Surface Runoff Harvesting:

This method captures runoff water from land surfaces, streets, or natural landscapes which reduces urban stormwater drainage issues and replenishes groundwater.

Groundwater Recharge:

Instead of storing water in tanks, rainwater is directed back into the ground to recharge depleted aquifers through infiltration wells or trenches. Restores the natural water table and can improve water availability in wells and boreholes.

DPU has committed towards the sustainable energy conservation. We collect roof top water with the help of 6” diameter pipe and supplied to 4 Nos. of RWH pits. Overflow of these pits are supplied to 2 Nos. of surface runoff RWH pits via storm water channels.

Total Percolation capacity is 4068 m3 per year i.e. 81.36 m3 per day.

Construction of Tanks and Bunds:

The construction of tanks and bunds plays a crucial role in water conservation, especially in areas prone to drought or water scarcity. These structures are designed to capture, store, and manage water for various uses, including irrigation, groundwater recharge, and domestic purposes. Below is an overview of the construction techniques and benefits of tanks and bunds for water conservation.

1.Tanks for Water Conservation

Tanks are artificially constructed reservoirs that store surface runoff, rainwater, or water diverted from streams or rivers. They can range in size from small ponds to large man-made lakes. They help capture excess rainfall during wet seasons and store it for use during dry periods, reducing dependency on external water sources and promoting groundwater recharge.

Benefits of Tanks:

• Water Storage: Provides a reliable source of water for agriculture, drinking, and other
