An energy-efficient Sunnyside home can save at least 25% on energy bills

Here at Sunnyside, we’re building energy-efficient homes but what does that mean for you in practice?

We use modern building practices and materials that are specifically designed to retain heat and minimise energy consumption. This translates to significant savings on your monthly energy bills, helping with the cost of living.

By using less energy, you’ll also be contributing to a smaller carbon footprint and reducing your overall impact on the environment.

So having a high-performance home means lower energy bills, and that helps the planet as well as your pocket.

To investigate further, we commissioned a report from energy consultants and delved into the data to identify the information that really matters to you.

We took two different types of property at Sunnyside:

  • our three-bedroomed home in the Orchard development, estimated on four occupants
  • our four-bedroomed home in the Woods development, estimated on five occupants

The top line results are that on average, there is a saving of 25% on energy bills in a new Orchard home, and a saving of 30% in your Woods home.

This is a simple statement to make – and it’s probably what you’re most interested in – but let us show you how we worked it out.

We would point out that our calculations are only a guide, and don’t necessarily reflect the actual use based on the number of occupants and the lifestyle of the home owner. But with that disclaimer in mind… read on!

ORCHARD

Typically the annual consumption of a similar size property to the three-bedroom Orchard home would be 14,900kWh.

Based on our consultant’s report, the typical annual consumption of the Sunnyside home would be 11,145kWh, which equates to a 25% reduction in fuel use and equates to an approximate monthly fuel bill of £139/month.

WOODS

Typically the annual consumption of a similar size property to the four-bedroom Woods home would be 21,300kWh.

Based on our consultant’s report, the typical annual consumption of the Sunnyside home would be 15,100kWh, which equates to a 30% reduction in fuel use and equates to an approximate monthly fuel bill of £165/month.

Sunnyside energy-efficient homes

All our homes are built with modern building practices and materials that are specifically designed to retain heat and minimise energy consumption, such as:

  • modern energy-efficient boilers
  • highly insulated loft space
  • highly insulated walls and floors
  • A-rated double-glazed windows
  • solar PV panels
  • energy-efficient exterior doors

In addition, we produce all our own timber kits on-site and our homes come with an NHBC 10-year Buildmark Warranty. The warranty ensures we have complied with the NHBC Standards which set out the technical requirements for design, materials and workmanship in your new home.

You benefit from a more comfortable home. Proper insulation and efficient heating systems help maintain a consistent and comfortable temperature throughout the year, eliminating draughts and cold spots.

And you’re future-proofing as with increasing emphasis on sustainability and energy efficiency, opting for a new build home positions you well for future regulations and potential changes in property value.

Industry standards

For domestic buildings, the Standard Assessment Procedure (SAP) methodology is used to check design options and assess regulation compliance. It’s the methodology currently used by the Government to estimate the energy performance of homes, and used to generate Energy Performance Certificates (EPCs) for all homes.

An EPC gives information on how energy-efficient a building is and how it could be improved.

The EPC shows:

  • the building’s “energy efficiency rating”, which gives you an idea of how much fuel bills are likely to be
  • the building’s “environmental impact rating”, which shows how much the building affects the environment with CO2 emissions

Both ratings are on a scale from A to G with A being the best.

An EPC is not a detailed assessment and is only based on regulated energy usage (space heating, cooling, hot water, lighting).

Sunnyside in-depth analysis (TM54 assessment)

We have taken things one step further in order to demonstrate the efficiencies and savings on your energy bills if you invest in one of our new homes.

We completed what is called a TM54 assessment of our properties. This is performance modelling and an analysis of regulated and unregulated energy consumption within a family home. Examples of unregulated consumption are the use of domestic appliances and electrical devices such as TVs, white goods and cooking equipment. These can have a significant impact on fuel consumption, depending on individual lifestyles, and are not taken into consideration when producing figures under a general EPC. This allows us to provide a clearer understanding of the predicted energy consumption and costs as detailed above.

(All our home owners are individuals and lifestyles differ, so for our calculations we estimated energy use from four occupants in the Orchard home and five in the Woods home. We presumed everyone was home every evening. During the week, we worked on 25% occupancy during the day, rising to 50% occupancy on weekend daytimes)
