CLIMATE CONTROL Training
The people in charge of keeping buildings running as they were intended must be properly trained in the usage and maintenance of HVAC. This is unfortunately often an afterthought, briefl y taking place during handover. Training should take place when there are any staff changes too. I suggest fi lming training as a loss of building knowledge is one of the most common reasons for breakdown in the soft landings process.
Monitoring As previously mentioned, one of the biggest issues with soft landings
in relation to closed-system HVAC is hidden problems. The best way to counter this is through real-time monitoring. We use technology that monitors parameters indicative of corrosive conditions, such as dissolved oxygen, pressure and galvanic currents. Readings are taken every 15 minutes, 24/7, which means corrosive conditions can essentially be stopped before major damage occurs. Indeed, it is widely recognised that simply monitoring corrosion levels will also give comfort that there is no risk from microbiologically infl uenced corrosion (MIC). Monitoring in this way ensures the continued health of a system,
reducing the need for adjustments and repairs during seasonal commissioning.
Proof Where an issue does arise, or to give end users confi dence in your
recommendations, proof is key. Real-time monitoring is the only defi nitive way to provide that proof; to accurately pinpoint when and why an issue occurred and/or show that the works carried out have been eff ective. The latter point can lead to more sustainable practices and reduce intervention, time and cost. In some instances, monitoring demonstrates that perceived problems are simply local operational issues and not system wide integrity failures, preventing expensive knee-jerk reactions, which usually involve volumes of water and chemicals. Overall, the reduction in sampling costs and the early indication of potential water quality deterioration prevents the need for drain downs and expensive fl ushing/cleaning operations if the water quality can be restored. BSRIA off ers the following guidance to navigate the soft landings process, which can be purchased individually or as a set: ■Soft Landings and Government Soft Landings (BG 61/2015) ■ How to Procure Soft Landings - specifi cation and supporting guidance for clients, consultants and contractors (BG 45/2014)
■The Soft Landings Core Principles (BG 38/2018) ■Soft Landings Framework 2018 (BG 54/2018) ■ Pit-stopping - BSRIA’s reality checking process for Soft Landings (BG 27/2011)
■Success Criteria for Soft Landings (BG 74/2019) ■Soft Landings Case Studies 2019 (BG77/2019).
Monitoring the performance of hydraulic closed systems leads to confi dence in the operational performance and consequent climate control. More than that, it is also a measure of capital plant effi ciency, leading to reduced running costs. If you are contractually obliged to deliver soft landings, then monitoring is a tool that will make your job easier, your customers’ happier and crucially, dramatically reduce the risk of liability for problems that could have been avoided.
