Is it MEES you’re looking for?

Mitch Layng believes that MEES offers opportunities if handled correctly. Here he considers the different stakeholders in the property sector and outlines the possibilities that lie in the new legislation for each.

The value of sustainability

As the property market becomes increasingly competitive, there is a need to differentiate through better building performance. Andy Lewry, James Fisher and Matt Holden discuss how sustainability results in high performance buildings.

Dementia care home chooses Lochinvar gas absorption heat pump

Renewable energy for a care home in Derbyshire that specialises in dementia is provided by an integrated heating and hot-water system using a gas absorption heat pump from Lochinvar. Solar PV panels were originally considered for the Callywhite Home, but on inspection it was decided that an Optimus gas absorption heat pump was more appropriate for this type of project. It also met planning requirements at a considerably lower cost that solar PV, even taking into account the potential solar feed-in tariff.
