Dan Slevin Discusses Energy Efficiency & Heat Loss on RTÉ Radio 1
Managing Director Dan Slevin recently featured in RTÉ Radio 1's "Drivetime" programme about improving energy efficiency in the home:
With energy prices remaining high across Ireland, many homeowners are looking for affordable ways to make their homes warmer without spending tens of thousands on a full retrofit. Home energy expert Dan explains on RTE Radio 1 why expensive upgrades aren't always the first answer. Through professional home assessments, he identifies exactly where homes are losing heat and provides homeowners with a practical action plan that delivers real improvements. The good news? Many homes can become noticeably warmer with relatively small, targeted changes.
According to Friends of the Earth, the Government's climate, energy and poverty strategies are still leaving many Irish households struggling with high energy prices, poor housing quality, low incomes, home energy heating dependence on fossil fuels Many homeowners assume the problem is simply expensive heating, when in reality, much of that heat is escaping through unnoticed gaps and poorly performing parts of the home.
One surprising finding is that a home's BER rating doesn't always reflect how comfortable it actually feels.For example, approximately 13% of Irish homes are rated below D, around 25% are rated D, around 35% are rated C. Despite this Dan says that around 30% of thermal improvement energy audit enquiries come from A-rated homes. This highlights an important issue. Although BER ratings provide a useful benchmark, quality control during construction and installation can have a significant impact on how warm a home actually feels. Even newer homes can suffer from air leaks, poor workmanship and inadequate sealing.
Rather than recommending expensive work immediately, Dan begins with a professional home assessment. During the energy home inspection visit, he identifies cold draughts, air leakage, poor insulation, heat escaping through hidden areas. Homeowners then receive a prioritised list of improvements, allowing them to spend money where it will have the biggest impact.
Deep Retrofits Aren't Always the First Answer Deep retrofitting can dramatically improve energy efficiency, but it's often beyond many homeowners' budgets. Dan recalls one homeowner receiving a quote of €51,000 for an external wall wrap before anyone had even tested the property for heat loss. Without proper diagnostics, homeowners risk spending thousands on upgrades that may not solve the real problem. Instead, start by identifying where heat is escaping.
Seal an Open Chimney. An unused fireplace can act like an open window. By properly sealing the chimney while maintaining appropriate ventilation, homeowners can dramatically reduce unwanted heat loss.
Don't Automatically Replace Your Windows. Replacing windows is one of the most expensive home improvements. However, Dan explains that many draughty windows simply need the window seals replaced. Over time, the rubber seals deteriorate, allowing cold air to enter the property. Replacing these seals can often restore performance at a fraction of the cost of installing new windows.
Insulate and Seal Your Attic Properly. A listener asked why their attic is unbearably hot during summer but freezing during winter. Dan explains that quality insulation works all year round. Good insulation keeps heat inside during winter, reduces overheating during summer, and improves comfort throughout the house. He also points out that while attics themselves are designed to be cold spaces, the rooms below them shouldn't be. Sealing the attic hatch alone can significantly improve temperatures on upstairs landings and bedrooms.
