Sunrise and Sunset:
The yellow section shows when the sun is up, and how this changes over the year.
The sunrise and sunset times shown in the chart are approximate.
They are accurate for the latitude, and show the precise amount of daylight.
The charts are made assuming that the location is in the middle of an evenly spaced time zone.
 For Lahore City, Pakistan, use latitude 31°33'N and longitude 074°20'E in the form. You'll need to know the time zone of the location.

Vehicle Ancillary Load Reduction Project Close-Out Report
INTRODUCTION

The amount of fuel used for climate control in vehicles affects our nation’s energy security significantly as it lowers the fuel economy of the 230 million light-duty conventional vehicles in use in the United States today. Researchers at the National Renewable Energy Laboratory (NREL), a U.S. Department of Energy (D ....etc

Abstract
An alternative method of distributing RF in buildings is proposed in which the heating and ventilation ducts are used as waveguides. Because of the relatively low waveguide loss, this method may lead to more efficient RF distribution than possible with radiation through walls or the use of leaky coax. Further, the use of existing infrastructure could lead to a lower-cost system. Initial experimental results are p ....etc

Automatic Ventilation Control

Introduction
This article describes the design of a portable automatic ventilation control system that also processes arterial oxygen saturation (SpO2) data from a pulse oximeter. The system, built around Freescale’s 8-bit MC9S08QG4 microcontroller (MCU), is designed to be a portable, automatic replacement for manual pulse oxygen and ventilation monitoring and control, requiring less human interaction during surgery. It can be particularly useful during surgery on infants. Overview All tissue ....etc

Introduction

Solar air conditioning refers to any air conditioning (cooling) system that uses solar power. This can be done through passive solar, solar thermal energy conversion and photovoltaic conversion (sun to electricity). New solar air conditioning research and development program, which should develop and demonstrate multiple new technology innovations and mass production economies of scale. Solar air conditioning will play an increasing role in zero energy and energy-plus buildings design.

ABSTRACT

In this present situation personal protection is an important factor. Although the primary approaches in any safety effort is the correction of the physical environment so that unwanted events cannot occur. It is sometimes necessary for economic or other expeditious reasons to safeguard personnel by equipping them individually with specialized personal protective equipment.

This seminar deals with some personal protections, Eye, Face Protection, Finger, Hand, Arm, Foot and Leg Protection, Noise Safeguards and Respiratory ....etc

Introduction:-
Energy Audit means the verification, monitoring and analysis of use of energy including submission of technical report containing recommendations for improving energy efficiency with cost benefit analysis and an action plan to reduce energy consumption. Energy audit is an important process to be carried out for energy conservation. In energy conservation, the thrust is given on the saving of energy while carrying out the required work. Some amount of energy is always required to carry out the req ....etc

VALVETRONIC ENGINE TECHNOLOGY
1. INTRODUCTION
The automobile has been providing individual mobility for more than 100 years. This mobility is made possible first and foremost by combustion engines drawing their power from fossil energy carriers, which, even today, provide the foundation in generating mechanical drive power in the automobile. The primary objectives in developing drive systems are to curb fuel consumption and reduce CO2 emissions. In an effort to meet this challenge, the automotive industry is developing suit ....etc

INTELLIGENT BUILDINGS
Energy in Buildings
Buildings are inherently linked to their usage and surroundings and hence their indoor environment is the result of a range of interactions affected by seasonal and daily changes in climate and by the requirements of occupants varying in time and space.
The design of buildings in the mid-late twentieth century has sought to eliminate the effect of outdoor daily and seasonal changes through the use of extensive heating, cooling, li ....etc

VENTILATION IN BUILDINGS
What is Ventilation ?
The process of removing used air by fresh air from buildings and spaces is called ventilation. This is done by Natural or Artificial methods
Effects of Ventilation :- 
1. To remove the used air from spaces/buildings.
To supply oxygen for humans.
Remove excessive moisture.
Remove excessive heat.
Cool the surroundings and freshen up the atmosphere in the building.
Composition of Air
Nitrogen 78%

Abstract
The purpose of this paper is to investigate using a numerical simulation (computational fluid dynamics or CFD) the effect of the air supply location on the design and performance of the displacement ventilation (DV) system. The results are reported in terms of thermal comfort and indoor air quality. The study focuses on a typical enclosure in CBIT under local thermal and boundary conditions. This includes several pollutants typically found such as carbon-dioxide and volatile organic compounds (VOCs) were inv ....etc

Heat Recovery Ventilation

Introduction


Heat recovery ventilation, also known as HRV, mechanical ventilation heat recovery, or MVHR, is an energy recovery ventilation system using equipment known as a heat recovery ventilator, heat exchanger, air exchanger, or air-to-air heat exchanger which employs a counter-flow heat exchanger (countercurrent heat exchange) between the inbound and outbound air flow.
HRV provides fresh air and improved climate control, while also saving e ....etc
