As Lord Kelvin famously said, "If you cannot measure it, you cannot improve it." Here at 77 West Wacker, despite extensive metering relative to comparable buildings, we have found a lack of visibility into energy consumption data is one of the greatest barriers to implementing energy conservation measures (ECMs).
The need for detailed energy consumption data
Ideally, building equipment and tenants should be sub-metered. It might be overkill to meter every individual piece of equipment, but if all supply fans, or all water pumps, or all chillers were grouped on a single meter, understanding building behavior would be greatly simplified. Tenants, on the other hand, are sub-metered. The issue is that building management and operations do not always have access to that data because tenant consent is required to view tenant usage data. Unfortunately, a consent form does not exist in our service area to allow that. The way tenants are currently billed assumes equal energy use on a square footage basis, and therefore, does nothing to promote energy efficiency. Knowing exactly how many kilowatt-hours are used by each tenant each month would allow building management to accurately bill those tenants, thereby incentivizing conservation on their part to reduce operating costs. As building managers around the country are charged with making their buildings more efficient, they will need the tools to do so. Read More
