As more of our everyday discussions centre around how we can each be kinder to our environment, our personal responsibility comes into focus. With Habattach, we set out to develop and design an offering that made energy efficiency a priority.  In the spirit of that same idea, we thought it would be beneficial to share a few steps you can take to increase the overall energy efficiency of your home.

Step 1: Proper Insulation and Creating a Building Envelope

Creating a building envelop is essential to maximising the efficiency of your home. A building envelope can simply be defined as the physical separator between the unconditioned environment outside, and the conditioned environment we have inside our home. Ultimately you want to create obstructions to water, air, heat, light, and even noise pollution.

Insulating your loft is one of the best ways to help in the development of your building envelope. With the right insulation between the joists in your loft, you able to keep more warmth in your living spaces. You can also take your lining a step further by also insulating the rafters to increase the warmth of your roof space as well. Let’s not to forget the added bonus of lowering your heating bills in the winter.

Upgrading your windows and doors to double glazing is another great method to better your house insulation. With single glazed windows, the warm air inside meets the cooler outside air and creates condensation on the inside of your windows. By fitting double glazing, the passage of cold or hot air from the outside to the inside of the house is reduced. This means the climate inside your home stays either warmer or cooler for longer, you prevent condensation, and reduce outside noises.

Step 2: Watching your energy consumption

Little things we do every day can help us save pennies, and over time those pennies do add up. By turning off lights in room when you leave or changing out older lightbulbs for their newer LED counterparts, you’re able to reduce your daily usage. Turning off switches when they aren’t needed for charging your mobile phone or unplugging small kitchen appliances when not in use can also help.

Have you ever taken the time to quantify how much energy you might be wasting? Investing in an energy monitor will help you to find out. They can cost around £25 to £40, but some gas and electricity companies give even them to customers for free. A quick conversation with your provider will determine if they offer monitors, if you are eligible, and what monitor you need.

Once you have found the right energy monitor for you, put it somewhere your whole family can see it. The kitchen or living room offer many highly visible places that allow everyone to see the monitor throughout the day. Some of these neat devices also work out how much your energy use is costing every day, providing you the information to be mindful of usage.

Step 3: Upgrade Hardware and Appliances

 You might not think you’re individual hot and cold taps make much of a difference to your energy consumption. Maybe your older boiler is still firing away quite well, and it seems there’s little point in replacing something that’s not broken. While replacing your plumbing or heating hardware can be costly, there are benefits to an investment in upgrading.

Newer boilers are designed to be more energy efficient, especially those with Thermostatic Radiator Valves (TRVs). When used in conjunction with a room thermostat, TRVs give you the opportunity to heat your home more efficiently by setting the temperature for each room. When the ambient room temperature reaches the setting, the TRV will automatically shut off the relevant radiator. You can also consider setting rooms that aren’t used as frequently at slightly lower temperatures.

A dripping tap can use as much as 3 litres of water per day, totalling up to 90 litres of water each month. Numbers like that really make you realise your washing money down the drain, quite literally. By upgrading your older or faulty taps, you will immediately be able to see an impact on your water usage. In a similar manner, switching over to a water-saving shower head will also have a positive impact on your water bill.

A proper cuppa can be the most quintessential part of daily lives, a creature comfort steeped in tradition. However, it isn’t necessarily the most ecologically friendly to boil an entire kettle of water when a single cup will do. There are a variety of eco-friendly kettles available that can boil your water more efficiently, only boil what you need, and keep your boiled water warmer for longer.
