Consider these 3 factors to Maximize Savings using Daylight Harvesting

Did you know that about 60% of the energy consumed in commercial offices is directly or indirectly related to artificial lighting?

Buildings worldwide consume 30% of the planet’s energy emitting 35% of the greenhouse gases and 40% waste.

If you are the project manager looking at sustainable energy production and wanting to significantly reduce building energy costs, then you should look at building lighting as a top priority.

But you’re probably wondering:

How does one go about fixing lighting costs? What are the things to look at to bring down this cost? What viable solutions are available?

This post will answer all these queries.

Let’s get started.

Energy Savings and Daylight Harvesting

Daylighting in Buildings

(Ref:http://retaildesignblog.net)

Much of the artificial lighting is converted into heat, raising the room temperature and increasing the cooling loads, thus increasing the air conditioning workloads in the buildings. This increases the carbon dioxide emissions and other greenhouse gases resulting in global warming.

With about 300 clear sunny days in a year in India, natural Solar energy lighting is a great way to improve the lighting of a building naturally and offers a great solution to the above problem. Not only does it bring in significant cost savings and sustainability but also improves the overall well-being of individuals for enhanced productivity.

Factors to look at to bring down energy costs:

  • HVAC Costs

HVAC refers to Heating, Ventilation and AC – the systems in a building to maintain optimum temperature, humidity and air quality inside the building to create a great environment.

Usage of artificial lights can put a lot of strain on the HVAC systems to maintain the optimum temperature and humidity.

A well-designed daylighting system can bring down the HVAC costs significantly.

Modern-day skylights are designed to reduce UV exposure and heat transfer and other devices like Solar Light pipes can be used due to their structure that are efficient at producing more light with less heat.

  • Lighting costs

Daylighting systems offer a viable solution to bring down the lighting costs. Daylighting systems have been found to reduce the overall lighting energy costs by 50-60%.

In another blog related to daylighting, we talked about ways to improve daylight in a building. These include:  Siting and Massing of buildings, Different modeling techniques, Integration of electrical controls etc

Consider these methods to maximize natural lighting in buildings.

  • Maintenance costs

Maintenance costs can be driven by the costs associated to maintain HVAC systems handling increased loads with the heat generated using artificial lighting systems.

These costs can be significantly brought down by using daylighting systems.

Summary

The major factors we looked at for energy costs savings are : HVAC costs, maintenance costs and factors maximizing daylight.

Our daylighting systems enable substantial energy efficiency with significant cost savings.
