The materials used in the construction, the design of each home, layout of the development, and energy efficiencies of the heating and hot-water systems, all help lower your energy bills and the carbon footprint of the development now and in the future.
Keeping your home warm and providing hot water is arguably the largest single consumer of energy in any home. So it’s important that this function is as energy efficient as possible. Our homes generally use condensing boilers with GasSaver systems; there may also be a ‘thermal store’ to assist with greater hot water needs.
Reducing water consumption, through devices such as dual-flush toilets and water aerators and restrictors on outlets, is an important part of our environmentally-responsible approach.
These devices can also reduce energy consumption in producing hot water. So you can have the same comfortable showers, with the benefit of a potential cost and energy-saving through using less hot water.
The Building Regulations set national and local authority standards for carbon dioxide emissions from new homes. Our new homes have been designed to meet these levels, as we know that CO2 reduction is a concern for many of today’s homebuyers.
On average, a Scotia Home emits 8 tonnes fewer CO2 emissions than a typical 1900s house and 2.2 tonnes less than a 1960s house.
We estimate that on average, a three bedroom Scotia home uses 392kWh/m2 less energy than a typical 1900s house, and 218kWh/m2 less than a 1960s house.
So by moving into a Scotia home you could be making a potential saving of £1,369 per year... that’s £115 a month!
Our homes give you the reassurance that you are taking a step towards greener living:
Condensing combination boilers
We install A-rated gas boilers, which provide a combination of central heating and hot water. This is a very efficient option for most homes.
For larger homes that need more hot water, we may supplement this with a FlowSmart system, which improves boiler performance and avoids the need for storing hot water in tanks.
The GasSaver unit extracts heat from the waste gases that are expelled through the flue. This is then used to pre-heat the cold mains water before it enters the boiler. This means the boiler uses less gas to produce heat and hot water – saving on energy bills and reducing emissions.
The thermal store, in larger homes using the GasSaver unit, further pre-heats and stores water, so the boiler works less to produce consistently hot water for a longer period.
Air-source heat pumps
In some situations, we use an air-source heat-pump system. This uses heat exchange with the ambient air to provide heating and hot water with no direct fossil-fuel consumption and minimal electricity use.
The position and size of radiators is carefully planned around room sizes and heat requirements, and complements the capacity of the boiler or heat source. Panels are designed to give the maximum heat output for the minimum surface area.
Heat is lost through the floor, walls and roof, and particularly doors and windows. Without careful design, thermal bridging lets heat escape easily, and wastes energy in heat generation.
Floors, walls, ceilings and roof
Where possible, these areas of your new Scotia home provide uninterrupted layers of insulation in addition to standard cavity walls, with particular attention to airtightness.
Modern A-rated double-glazing is used, generally with solar/thermal glass, gas-filled cavities and warm-edge insulated spacer bars. This reduces heat loss and maximises solar gain. The frames are compartmented to reduce heat loss, and weather-seals provide full protection from the elements.
External doors are of composite construction with internal insulation and draught-proofing to minimise heat loss when closed. Glazed doors have similar thermal properties to windows.
