Renewable Energy and Energy Efficient Smart Technologies

Watch the videos below for what we believe is a balanced view on both sides of the global warning debate.



Why are Renewable Energy Systems required in Irish Buildings?

Evolved Energy Solutions offer expert advice, specification and design services to a range of industry professionals aimed at ensuring Part L compliance and suitable mechanical services options for the end client. Although a renewable energy system may comply with Part L of the Irish Building regulations it will not ensure a happy customer at the end unless it is designed to meet their needs. The 2011 Irish Building Regulations Part -L Conservation of Fuel and Energy - Dwellings requirements shall be met by the following outline methods.

(a) providing that the energy performance of the dwelling is such as to limit the calculated primary energy consumption and related carbon dioxide (CO2) emissions insofar as is reasonably practicable, when both energy consumption and carbon dioxide (CO2) emissions are calculated using the Dwelling Energy Assessment Procedure (DEAP) published by Sustainable Energy Authority of Ireland ( A Building Energy Rating Certificate) 

(b) providing that, for new dwellings, a reasonable proportion of the energy consumption to meet the energy performance of a dwelling is provided by renewable energy sources.

(c) limiting heat loss and, where appropriate, availing of heat gain through the fabric of the building;

(d) providing and commissioning energy efficient space and water heating systems with efficient heat sources and effective controls;

(e) providing that all oil and gas fired boilers shall meet a minimum seasonal efficiency of 90%;

(f) providing to the dwelling owner sufficient information about the building, the fixed building services and their maintenance requirements so that the building can be operated in such a manner as to use no more fuel and energy than is reasonable.

Here are some of Evolved Energy Solutions preferred renewable energy technologies that we know can work well in Irish buildings when installed professionally and in well constructed buildings. Evolved Energy Solutions has a large network of supply and installation companies who we can recommend with confidence. One of the best indirect savings that Evolved Energy Solutions provides its clients with is significant savings on product supply chains. We cut out the middle men and give you the most suitable product for your project.

1 Geothermal and Air to Water Heat pumps 

A heat pump is a device that transfers heat energy from a heat source such as ground surface water or the air  to a heat sink such as a house heating system or buffer tank.  A heat pump uses some amount of electrical energy to accomplish the desired transfer of thermal energy from heat source to heat sink.

When a heat pump is used for heating, it employs the same basic cycle used by an air conditioner or a refrigerator but in the opposite direction, releasing heat into the conditioned-space rather than the surrounding environment. In this use, heat pumps generally draw heat from the cooler external air or from the ground.

Evolved Energy Solutions keep up to speed with a large array of renewable energy systems and smart technologies available to the Irish market place. Rather than select one single brand or product for every client, we select the correct brand solutions for individual projects.

Our belief is that personal and corporate responsibility must play a large role in slowing down the current rate at which we are depleting the Earths finite fuel resources. Renewable Energy products and smart technologies play a vital role in achieving a reduction in current COČ emissions. This does not mean renewable energy products will result in a meaningful reduction in your companies energy costs. Accurate non biased return on investment calculations should be carried out before installing renewable energy systems.

2 Solar water heating and Solar hot water

Solar water heating (SWH) or solar hot water (SHW) systems comprise several innovations and many mature renewable energy technologies that have been well established for many years. In Ireland the most common system found remains the hot water only system. Evolved Energy Solutions believe that while laudable from a carbon cutting point of view and potentially ensuring partial compliance with the 2011 Irish Building Regulations Part -L Conservation of Fuel and Energy requirements, hot water only solar systems offer very low return on investment from a financial point of view. 

SWH systems are designed to deliver hot water and assisted heating energy for most of the year. They work particularly well in low surface temperature heating system such as Underfloor Heating. However, in winter there sometimes may not be sufficient solar heat gain to deliver sufficient hot water. In this case a gas or electric booster ( heat pump)  is normally used to heat the water.


3 Secondary heating system wood burning stoves

wood-burning stove is a heating appliance capable of burning wood fuel and wood-derived biomassfuel, such as wood pellets. Generally the appliance consists of a solid metal  closed fire chamber and an adjustable air control. The appliance will be connected by ventilating stove pipes to a suitable chimney or flue, which will fill with hot combustion gases once the fuel is ignited.  

As the Irish building regulations become more and more advanced the inclusion of a renewable energy secondary heating system is becoming a greater requirement. We feel stoves offer Irish clients a fantastic "quick" heat up option on a particularly cold spring / summer evening if required rather than having to heat the entire mass of a large property using a geothermal of solar assisted heating. Practical low tech solutions to heating requirements are often the first choice option for our client base. 








From Baselworld 2016, replica watches sale lastly provides on the guarantee in order to revise the most popular Seamaster Earth Sea selection along with "Master Chronometer"-rated, fake rolex sale actions. This really is additionally the very first main revise towards the Seamaster Earth Sea breitling replica because the debut from the 9300 movement-based Seamaster Earth Sea Chronograph wrist watches within 2011. In the following paragraphs, we proceed cartier replica uk using the up-to-date Omega Seamaster Earth Sea Grasp Chronometer Chronograph, that is just like the actual outgoing design, however by having an rolex replica motion plus some general style improvements as well as refinements. hublot replica uk is not precisely certain exactly what this really wants to phone this particular watch, evidently. Both recognized titles tend to be "rolex replica sale forty five. 5mm Chronograph" as well as "Omega Seamaster Earth Sea Grasp Chronometer Chronograph. inch tag heuer replica uk each tend to be correct, or maybe there's an additional recognized title. The point is, the actual wrist watches are actually good, despite the fact that presently there is probably not critically persuasive causes of proprietors from the outgoing era Omega Seamaster Earth Sea Chronograph wrist watches in order to update.
