Heating and insulating a 1870's traditional stone building.
We helped the owners of this traditional stone building, by the Dighty Burn in South East Angus, to dramatically increase the comfort of their family home and reduce energy bills with innovative infrared heating and insulation advice and implementation.
Burnside was originally built in the 1870’s. After generations of varied use, this large detached steading was falling into disrepair and was converted to a family home in 1998.
This traditional stone building is North facing and, as is typical for such a countryside location, there is no access to natural gas. Existing heating was provided by an oil-fired boiler and, although insulation was installed in 1998 the insulation values in the property were extremely poor.
With increasing fuel costs and a desire to carry out further modernisation works to their property, the owners decided it was time to take expert advice on which energy efficiency improvements could be achieved.
GoSustainable was appointed to assess the property, recommend the best plan of action and implement the energy efficiency measures.
GoSustainable carried out a Green Deal Advice Report (GDAR) to assess the viability of energy efficiency measures. The report is in two parts:
We completed a full technical survey of the property and produced an Energy Performance Certificate (EPC) identifying the current and potential energy efficiency of the property. We then identified a range of measures that could be introduced to improve the energy efficiency of the property and the associated costs to implement these.
This report helps to identify the annual cost savings to the home depending on the energy efficiency measures introduced. This determines the level of financial support available through the Energy Company Obligation (ECO), part of the government’s commitment to reduce carbon emissions.
The Internal Wall Insulation measure on its own forecast the following savings:
|Annual||x 36 years
|Carbon Saving (tonnes)||6.680||180.360|
Internal Wall Insulation
Installation of Knauf Thermoshell Internal Wall Insulation system throughout the property. Internal insulation, known as dry-lining, is where a layer of insulation is fixed to the inside surface of external walls.
As the floor was solid stone construction we recommended raising the floor by approximately 50mm and including a Kingspan rigid insulation board into a new floating floor. Insulation of a floor will significantly reduce heat loss; this will improve levels of comfort, reduce energy use and lower fuel bills.
Warmcel insulation dry-blown pneumatically into position (400mm depth) to provide a complete fill between and over joists, leaving no air gaps through which warm air can escape.
Infrared Heating System
A 13.46kw Redwell infrared heating system was installed throughout the building using a combination of wall and ceiling mounted heating panels, fully programmable using Honeywell and Salus thermostats. Infrared panels installed range from simple white panels to bathroom mirror panels, to custom printed artwork panels to blend with the interior decor.
Replacement of existing recessed ddownlightingwith low energy alternatives. Lighting accounts for 8% of a typical household energy bill: cutting your light usage is one of the easiest ways to save energy and money in the home.
Installation of 3.9kw of Solar PV to the South-facing roof elevation.
It is too early to produce full stats for this project but initial monitoring indicates an excellent 40% reduction in energy costs.
We achieved a very substantial Energy Efficiency increase from a G to a C rating. The Carbon Emissions Rating also improved from an F to an E rating. Our happy customer reports an instantly noticeable difference to the thermal comfort of the home. We will update results as they come in.
