9 simple ways to save on heating, ventilation and air conditioning costs

Heating costs are a big part of your energy budget, so save with these simple tips!

Heating and hot water have the highest energy levels of all total energy use. It can account for a massive 60% of the total energy use by households and business worldwide. This can be reduced however through using efficient heating systems, ones which operate at specified levels whilst giving substantial savings to the customer. Below we give three key was to cut your heating energy bills:

1. Replacing those inefficient boilers

Replacing inefficient boilers may seem a costly method, yet it’s a method that pays off in the long term. Always keep in mind that the latest Building Regulations have set minimum efficiency standards for new and replacement boiler installations, so failure to comply may have a bad outcome. Higher efficiency boilers may be specified and you can gain much higher savings from a more energy efficient heating system.

2. Installing de-stratification fans can eliminate the need for heaters

Often in commercial or industrial buildings, you’ll find that high ceiling are a common feature. Inhabitants will often use warm air heaters to make up for the cold air in the bigger space, yet you can actually use de-stratification fans to reduce energy bills by 20%. They work by simply blowing warm air down to ground level where it’s required instead of allowing heat to go through its natural process of rising.

3. Turn the heating down!

It’s possibly the simplest point on this list; turn the heating down! Lowering your heating by just 1°C can potentially reduce your annual heating bill by a huge 8%, so be sure to reduce the temperature levels on the thermostat down to the minimum level of comfort.

Having good ventilation in a building is essential – it provides you with fresh air whilst helping protect the building against damp and condensation, something which can cause bad health if it takes hold of the property. Unnecessary ventilation procedures will waste energy and more often than not, they will cost you a lot of money. Ventilation accounts for nearly 30% of heat loss in most commercial buildings, which is a waste of both energy and money. It’s estimated that 25% is wasted in industrial buildings. Below are three ways to cut back on your ventilation draining energy bills:

1. Time settings

Time settings can be a vital way for you to cut back on your energy bills. Make sure that fans are only running when they’re required to do so. Failure to do so not only wastes energy, but also removes heat from the building.

2. Motors

When you’re considering buying new motors, always be sure to opt for higher efficiency motors as these will save you up to 5% on energy costs.

3. Fans

Variable speed fans have the ability to slow down when ventilation demands decrease, therefore saving energy that it would otherwise waste. This will save money on electricity as well as reducing heating/cooling costs.

Air conditioning can be expensive, responsible for a big chunk of your energy budget. In fact, air conditioning can increase a building’s energy consumption by up to 100%. Though air conditioning uses lots of energy, many modern organisations choose to use it as part of the electronic transformation seen in most offices. IT equipment produces a lot of heat, so air conditioning is now mandatory.

Luckily,  simple, low-cost ways to save energy are available to yourselves and these tips will make your air conditioning system more efficient. Here’s the 3 tips below:

1. Temperature control is important

Make sure that your air conditioning doesn’t operate below a point of 24°C.

Making sure that you don’t have the heating and cooling systems competing with each other will often save you a considerable amount of money, it’s a pointless battle that will only have poor effects on your wallet. The best way to keep temperature controlled is through a gap (known as a ‘deadband’) that is situated between your heating and air conditioning control temperatures.

2. Free cooling coils

Free cooling coils utilise the temperature of the outside air as a source of cooling for air conditioning systems. In the UK climate, this is ideal as when it’s sunny, it’s mostly still going to be cool outside! This cuts considerable costs off of your bill as you don’t need to use nowhere near as much energy to produce cooling for the air conditioning system.

3. Variable speed drives can save you money

Don’t produce more cooling than is necessary – this simply wastes money and energy that could be used elsewhere. Variable speed drives can manage the output of your air conditioning system to meet your needs throughout the day, ensuring that the energy is being used wisely. Naturally, this will be a massive help towards energy costs.

What Energy Assessment means to you

An energy assessment is an inspection, survey and analysis of energy flows for energy conservation in a building aiming to reduce the amount of energy input into the system without negatively affecting the output.  When the object of study is an occupied building then reducing energy consumption while maintaining or improving human comfort, health and safety are of primary concern. Beyond simply identifying the sources of energy use, an energy assessment aims to prioritise the energy uses according to the greatest to least cost effective opportunities for energy savings.

The term energy assessment is most commonly used to describe a broad spectrum of energy studies ranging from a quick walk-through of a facility to identify major problem areas to a comprehensive analysis of the implications of alternative energy efficiency measures sufficient to satisfy the financial criteria of sophisticated investors. Audit is required to identify the most efficient and cost-effective Energy Conservation Opportunities (ECOs) or Measures (ECMs).

The main issues of an energy assessments are:

  • The analysis of building and utility data, including the installed equipment and analysis of energy bills;
  • The survey of the real operating conditions;
  • The understanding of the building behaviour and of the interactions with weather, occupancy and operating schedules;
  • The selection and the evaluation of energy conservation measures;
  • The estimation of energy saving potential;
  • The identification of customer concerns and needs.
