Energy efficiency in existing buildings: new solutions to meet new standards

Thursday, March 10, 2022

In the first part of this blog, we looked at the major implications for existing buildings of new EU Minimum Energy Standards that are expected to come into force in 2027. While no one should underestimate the scale of the challenges ahead, this concluding part will focus more on the positives – specifically, the growing pool of technologies that can improve the efficiency of existing structures.

This is good news, given that the European Commission has estimated that around 75% of buildings in the EU are energy inefficient (1). And with more demanding regulations due in 2033, property owners and landlords have no time to waste in finding solutions that can track consumption and save energy.

Thankfully, this is definitely one area in which technology has kept pace with changing needs. Priva itself is a major player, and over time has evolved a range of building automation and energy management solutions – to which digital cloud-based services are a recent addition.

But it is the Priva Blue ID building management system that continues to be our flagship. Everything about this system is geared towards reducing environmental impact. That starts with the installation process because Priva Blue ID is independent of field equipment. As a result, existing equipment and cabling can be reused, which also makes it the perfect system for renovations.

With its IP-based messaging, Priva Blue ID can be accessed anywhere, anytime. Backed up by comprehensive energy monitoring and reporting, this ensures users can make vital adjustments in a totally flexible way. The result is a new level of control and flexibility for managing a building’s energy consumption. So much so that it’s common for customers to benefit from double-digit percentage energy savings.

Although larger organisations were the initial main audience for Priva Blue ID, the system is now delivering huge energy savings for a wide range of customers. So whilst the S-Line version continues to be popular for more ‘mission-critical’ environments, the compact C-line HVAC controllers are finding favour in primary schools and smaller office blocks.

With hybrid working on the rise, and more people spending at least some of their working week based at home, remote access is becoming a big part of energy management. The cloud is already proving itself to be a major enabling factor here. Hence our development of Priva Digital Services – a suite of cloud-based digital solutions that can be scaled up or down as needed.

While three different packages offer varying functionality, all provide online-based Building Operator features. These allow users to navigate their building, change set-points, view live data, and manage alarms. Not only can this highlight opportunities to save more energy, it can also identify problems before they have a serious impact. Also, in the highest ‘Plus’ tier, Priva Analytics makes it possible to create and share automatic data reports.

With climate change also beginning to impact upon access to buildings, having an energy management system that is always available is going to be hugely important. In the unexpected downtime brought by the pandemic, a lot of companies will have thought about whether they have the technologies they need. Accessible building management is surely one of the soundest investments possible since it can improve company performance and help meet the new regulatory requirements.
