Designed and patented by Irish firm NuTech Renewables, solar enhanced ventilation aims to bring big energy and cost savings to the retrofit market by combining solar and ventilation technologies. NuTech’s Bill Quigley explains how it works.

Passive houses have long been considered the ultimate in low energy buildings. So when it comes to BERs, why don’t they always get a straight A? Lenny Antonelli investigates.

The introduction of smart metering later this year presents a great opportunity to engage Irish people en masse into substantially reducing their energy consumption, simply by showing them how much electricity they’re consuming, and how much the cost varies at different times of the day.
