About JOT Energy Consultants

Jeff O Toole established JOT Energy Consultants in 2010 due to the apparent need for independent energy consultants in Ireland. Having spent five years during the building boom as a construction site manager, it was obvious that the program was the priority, and energy performance and conservation were not. He quickly realised that a quality project does not come down to how quickly it can be built but rather how well the building functions and how energy efficient it can be within the constraints of the budget and the time frame.

Frequently Asked Questions

The way we build, heat, run, use and manage our buildings is changing at an alarming pace and trying to keep up with the pace can become overwhelming. We have so many decisions to make when we decide to take on a building project. The priority for most is have something comfortable that doesn’t cost a fortune to run. A good energy consultant will advise on the most cost effective building solution that meets the energy performance Targets set out in the Building Regulations without compromising on quality

High electricity costs can be associated with washing machines, dryers, electric showers, electric heating, heat pumps, circulation pumps and many other things. an energy consultant can set up a monitoring system on your house to assess what is using the most energy and how savings can be made

The BER rating can be improved in so many ways but the best improvements are typically achieved by insulating the roof and the walls, replacing single glazed windows, upgrading the heating system and heating controls and improving air tightness. Other things that make small improvements are low energy lights, replacing circulation pumps and adding a lagging jacket on hot water cylinders

If you have natural ventilation and you get an airtightness test result less than 3m3/hr/m2, your home is too airtight. You need to introduce mechanical ventilation to help deliver adequate fresh air

If your home has a lot of condensation on the windows, problems with mould in the corners of bedrooms and is generally stuffy, the chances are you have a problem with ventilation. If you live in a new dwelling with MVHR and the air is very dry or you have similar problems to the previously mentioned, the chances are you have a ventilation problem.

There is no best building system! All systems have their own pros and cons. They best system for one person may not be the best system for another. A good energy consultant will identify what is important to you and devise the best solution around your demands. Some of the criteria people consider is cost, efficiency, speed of construction, user friendliness, fuel preference, location, thermal mass, wall type, insulation type, occupancy, temperature, living habits, ventilation, type of windows, type of heating, water efficiency, renewable energy, environmental impact etc.
