The UAE has one of the highest per capita consumption rates of water in the world and relies on energy intensive, desalination processes to obtain fresh water. Energy and water management are, therefore, highly debated and important topics, which have significant implications for Facilities Management (FM).
In a recent interview with the Grid Initiative, KAIZEN’s Donna Meyrick discussed the latest trends in water and energy management in FM. These aspects of asset management have, over the past couple of years, become increasingly significant as they can potentially reduce overall returns to landlords.
There is a recognized need in the UAE to rationalize water and electricity consumption in order to reduce carbon-intensive activities. This has increased the region’s environmental awareness and increased the momentum for improved water and energy management. An increased understanding of carbon credit trading has further added to people’s awareness and concern about these issues.
In response to these financial and environmental areas of concern, KAIZEN recommends that appropriate water management to be implemented across all property portfolios.
Using automated irrigation systems to optimize water distribution in landscaped and foliage areas may reduce water consumption in a project. In new developments, gardens can be stocked with more regionally appropriate plants and trees, which have lower water requirements.
The implementation of a number of other methods is a great way of getting people involved and interactive in addressing this environmental concern. Such methods include the installation of double flush systems and waterless urinals and aerators for WCs. Other initiatives may include waterless car cleaning.
KAIZEN highlights the management of chillers and chilled water as one of the most effective energy savings that can be made.
A recent cost benefit analysis for a commercial property (Loft Offices in Media City) has been undertaken by KAIZEN. The results of this analysis indicated that actually replacing five of the chillers was more effective in reducing the landlord’s operational expenses than maintaining this asset until its manufactured expected expiry.
KAIZEN therefore tries to ensure that all projects use a Building Management System (BMS) for chilled water systems. This ensures effective use of energy by optimizing the difference between the temperatures of supply and returned chilled water (delta T). Through implementation of such measures, KAIZEN is enhancing the financial and environmental sustainability of property in the UAE.
