Energy Upgrades We Can Provide

External Insulation:

This form of insulation is a simplistic yet innovative approach to maintaining optimum levels of heat within a building and employs a form of insulation to the exterior of the building. External insulation is achieved by a composite cladding system which encompasses insulation and waterproof coating which is applied to all external surfaces of a building. Benefits of external insulation include increased comfort levels, improved insulation properties and also improved cost efficiency.



Internal Insulation:

This form of insulation is also a simplistic approach to maintaining the desired level of heat within a building. Contrary to external insulation, internal insulation involves fixing an insulation board to the interior walls and casing it with a vapour barrier layer and also plaster board. The layer of insulation can be up to 70mm in thickness. The benefits of internal insulation include a reduction in heating bills, reduction in GHG emissions and also increased comfort levels.



Cavity Wall:

This technique of insulation is an effective and popular way to save energy and money. Cavity walls consists of two layers known as "skins" which are separated by a concave space, the "skins" are usually brick or concrete block. Insulation through cavity walls is achieved by drilling small holes at pre-defined intervals from the outside of the building; the drilled holes are then pumped with insulation and fill the cavity space within the wall. Cavity wall insulation is a cost effective way of reducing heat loss by up to 35%, it is also environmentally friendly as well as being cost effective.

Attic Insulation:

Proper insulation and air sealing of the attic space will aid in reducing a buildings energy bills. This form of insulation is aimed at providing a barrier to heat loss in an area of the building is prone to substantial heat loss. It is done by sealing all attic to home air leaks, covering openings such as dropped ceilings and bulkheads and also sealing around the chimney area with a high temperature caulk.



Heat Recovery:

Heat Recovery Ventilation (HRV) is an energy recovery ventilation system. The technology uses equipment such as heat recovery ventilators, heat exchangers and also air exchangers that initiate counter current heat exchange between the inbound and the outbound air flow. HRV enables fresh air and also improved climate control. There are a number of benefits that come with HRV which include improve comfort levels, condensation control, economic stability and also improved health benefits for occupants.



Heat Pumps:

This device allows for the transporting of heat at a lower temperature from one location, which is known as the source to another location at a higher temperature. A heat pump can be used to provide both heating and cooling. A heat pump consists of a compressor and two coils which are surrounded by aluminium fins to aid in heat transfer. In heating mode liquid refrigerant extracts heat from the outside coils and air, the indoor coils transfer heat the refrigerant as it condenses back into a liquid. A reversing valve is fitted near the compressor which can change the refrigerant flow for cooling as well as for defrosting the outdoor coils in winter. The benefits of heat pumps include year round usage as it has two modes of operation; the use of heat pumps also improves the energy efficiency of the building.

Solar Panels:

A solar panel is a device that converts light from the sun into electricity. A solar panel is a collection of solar cells, the more light that hits a cell the more power generated. When solar cells are exposed to light the p-n junctions which are present within the cells convert the energy from sunlight into electrical energy. The energy generated from the photons striking the surface of the solar panel enables the electrons to be placed out of rhythm and released. The solar cells pull these electrons into a current from which metal contacts in the solar cell produce electricity. Benefits of solar panes include independent production of electricity which means reduced cost. There are also significant environmental benefits of utilising solar panels.


Similar to solar panels photovoltaic's (PV) is a technique of producing electrical energy by altering solar radiation into direct current electricity using semiconductors. The key difference between PV and solar panels is that PV absorbs heat radiation while solar panels are primarily designed to obtain energy from light. PV cells work by capturing the energy which is created when a photon strikes a PV cell. When this occurs the energy of the photon is transferred to an electron in an atom of the cell which in the case of the PV is the semiconductor. This newly created energy enables the electron to escape from its normal position to form of the current in the electrical circuit. The benefits of PV panels are much the same as solar panels as they provide an independent source of electricity and have associated environmental benefits; a benefit of PV which is not applicable to solar panels is that PV's are not dependant on sunlight exposure, only the heat associated with solar energy.

Effluent and Water Treatment Systems:

Both effluent and water treatment systems are effective waste water treatment systems that our chemically free and non biological which consumes low amount of electrical power. Water treatment systems are most commonly used in tannery plants and the textile industry. Treatment systems usually combine a number of different methods and techniques to achieve accurate treatment; these include disinfection such as ultraviolet light, filtration such as carbon filters and also deionization which is centred on removing dissolved substances in ionic form. Benefits of these treatment systems include cleaner and healthier drinking water, there is also the improve benefit of water quality which does not result in high energy costs.



Heating Controls & Boiler Upgrade:

As the name suggest heating controls allow for the level of heat in a building to be controlled. Heating controls enable occupants to manage the level and location of the warmth when the heating is on. The majority of heating control systems consists of a timer and a room thermostat or a combined programmable room thermostat. Upgrading the boiler can also be a key area of improved energy efficiency and should be considered if a boiler is older than 15 years as efficiency would be less than 70%. Benefits of both heating controls and boiler upgrades include a reduction in the amount of energy that is used which in turn results in reduce the level of CO2 production and also reduce the cost of the energy bill.

Wind Turbine:

This is a device which converts kinetic energy from the wind into useable mechanical energy. If the mechanical energy is utilised to produce electricity, the device is referred to as a wind generator. A wind turbine works on the opposite principle of a fan, instead of using electricity to make wind, wind turbines use wind to make electricity. The wind turns blades of the turbine, which spins a shaft that is connected to a generator which produces useable electricity. Wind energy is a clean source of fuel, which means it is a low carbon technology; it also is an independent means of generation which promotes sustainability, another benefit of wind energy is that it is one of the lowest priced renewable options available to Ireland.
