Tankless Water Heaters – Their Efficiency and Convenience

The comfort and convenience of a seemingly endless supply of hot water are for many people with conventional systems, a sought after dream. However, arguably, tankless water heaters or “Demand-type” water heaters have been available in our lives for a significant number of decades. Various reports indicate that this water heating process, for users of 186 litres or less is capable of producing energy efficiency, 24% to 34% greater than the usual water tank heaters. This factor is just one reason contributing to more consumers installing tankless water heaters in their homes!

How the tankless system works

Simply put, a tankless heater provides a flow of hot water in comparison to traditional systems that store and heat water as and when needed. It’s achieved with gas or an electric source that heats the water before it flows into the hot water utility. In comparison to a tanked heated water system, the tankless application does not require the use of a

5 Things to Consider When Choosing a Commercial HVAC System

Selecting a commercial HVAC system for a building is no easy task. However, if you know what to look for, you have nothing to worry about. To make things easier for you, here are 5 things to consider when choosing a commercial system.

You can save on energy costs by selecting an HVAC system that has good energy-efficiency ratings. Here are some energy ratings you should keep in mind when making your decision.

Seasonal Energy Efficiency Ratio is an efficiency indicator for air conditioners. Higher SEER ratings will result in better energy efficiency. The minimum SEER rating in the US is 13. Anything above is considered to be highly efficient.

Heating Seasonal Performance Factor (HSPF) is used to measure the efficiency of the heat pump. An HVAC system with an HSPF rating of 8.2 or more is considered highly efficient. HVAC systems don’t have an HSPF value below 7.7.

Annual Fuel Utilization Efficiency (AFUE) is used to measure the efficiency of heating

Energy Efficient Buildings With Glazed Aluminium Windows and Doors

Energy efficient buildings have been seen as a luxury rather than a necessity in some countries. With many countries worldwide introducing new legislation to improve on the total building energy-efficiency footprint, it has prompted for an essential holistic look at building processes. Leading aluminium extrusion manufacturers have taken this environmental requirement to heart and have introduced thermally efficient window systems which, along with their other products, comply with national standards.

Conservation of energy is of serious concern in building design as a large amount of energy is expended in the heating or cooling of interior spaces. One of the priorities is to cut down on the internal illumination by increasing glazing to allow for increases in ambient light. This however increases the heat loss or gain to these spaces as windows and doors can notoriously be bad insulators.

Energy-efficiency in building and in particular glazing systems has been reserve

What Are the Benefits of LEED Certification?

The acronym LEED stands for Leadership in Energy and Environmental Design. This program assesses a building design, from conception to completion, in terms of energy efficiency, air quality, water usage, and the choice of building materials. It also addresses the environmental factors, including access to public transportation and responsible use of land.

The program itself is sponsored by the United States Green Building Council (USGBC). Projects that participate in the program are awarded certification based on different certification criteria. With each of the criteria, different points are awarded -Certified (40-49 points), Silver (50-59 points), Gold (60-79 points), and Platinum (80+ points).

Why LEED Certifications Are Beneficial

Obtaining LEED certification demonstrates environmental responsibility and responsible building practices. Not only can this boost the building owner and contractor’s reputation, but it also provides the fra

Going Green Makes a Lot of CENTS

You’ve likely heard the term “going green” and why it’s good for the environment. But what about the dollars and cents aspect? There are any number of reasons why building and business owners should invest in energy-efficient upgrades in their multi-family properties.

First, bear in mind how much LESS efficient older structures and related appliances and systems are compared to newer ones. Let’s take the example of a Heating, Venting and Air Conditioning System (HVAC) system on but one of your properties. Older buildings often have older HVAC systems with Seasonal Energy Efficiency Ratio (SEER) ratings of only 6-11. Conversely, a new building, or one with an upgraded HVAC system, has a SEER rating of 15-20 – or more. And energy savings = cost savings.

* As an advertising tool. Being seen as a developer interested in “going green” will reap dividends as you’ll be seen as being environmentall

5 Home Energy Areas To Consider

When most home buyers look for a house, of their own, they consider many factors and considerations, including whether it meets their needs, in many ways, and is affordable, for them. When considering these economic factors/ considerations, very often, little attention, is paid, to the continuing costs of utilities, especially for heating, air conditioning, and electric. As a Real Estate Licensed Salesperson, in New York State, for over a decade, as well as a homeowner, and an investor in a few rental properties, I have come to recognize and realize, it’s very important, essential, and relevant, to pay keen attention to energy costs and considerations. This article will, therefore, attempt to briefly review, examine, consider and discuss, 5 specific areas of a home, which may have a significant impact.

1. Windows and Doors: Energy studies often indicate, perhaps, the largest loser of energy, in most homes, is via, the windows and doors. We often refer t

30% Of Energy Used In A Commercial Building Is Wasted Because Of Inefficiences

This statistic as published by the Environmental Protection Agency (EPA) is staggering. The energy wasted is due to inefficiencies primarily in the mechanical, electrical and plumbing systems (MEP). If your business is in manufacturing the energy wasted can be significantly more due to the waste heat generated which is often exhausted to the atmosphere. Facilities that operate 24/7/365 such as resort hotels, hospitals, municipalities, institutions, etc., can have a tremendous energy spend as well.

That is why a 15-Step, staged Comprehensive Energy Efficiency Process is recommended to maximize results. Similar to the approach as recommended by the EPA’s Energy Star Program which accounts for the interactions of all the energy flows in a facility. Each stage includes changes that will affect the upgrades performed in subsequent stages, thus setting the overall process up for the greatest energy and cost savings possible. Perfect examples are how the lighting affects the h

Title 24 Compliance Now Heavily Influences Policy Worldwide

Since the 1970s, California has led the way in building and energy efficiency policy. Being Title 24 compliant isn’t only good for California, it brings new services, technology, and products to market that the entire world benefits from. The power of being title 24 compliant is further amplified because California is the fifth-largest economy in the world (recently passing the U.K.)

During the 1970s, ecology and energy conservation concerns were mostly either ignored or a hotly debated political subject. This was long before ‘green friendly’ was a widespread concept. But even then, California was a true leader concerned with the state’s skyrocketing energy consumption and the unlikely ability of the energy infrastructure to keep up with demand.

The California Title 24 Effect

The California Building Standards Commission created Title 24 in 1978. Throughout the years, it has been updated with increasingly robust efficiency

Decoding the Ductwork Design Process, Methods and Standards

Today, one of the significant objectives in MEP engineering design for HVAC design engineers is to improve energy efficiency, maintain air quality and thermal comfort. Energy efficiency, air quality and comfort in a building depend on how heating, cooling and air distribution systems are designed and this is where careful ductwork design plays a significant role. Ductwork and HVAC system design are important as it ensures indoor air quality, thermal comfort and ventilation. If the HVAC system and ducts are not designed accurately, it could lead to poor air quality, heat loss and make the conditioned space in the building uncomfortable.

The primary function of the ductwork design system is to ensure a least obtrusive channel is provided through which cool and warm air can travel. When designed accurately, HVAC air distribution systems will play an important role in countering heat energy losses, maintaining indoor air quality (IAQ) and providing thermal comfort.
