About this event:

Join us for our upcoming Lunch & Learn session which covers HVAC Retrofit Best Practices for GHG Emissions Reduction.

This session includes live opening remarks and a brief presentation on local energy efficiency (EE) incentives, then we will offer a viewing of pre-recoded education content and a networking opportunity at the end. This Lunch & Learn is FREE for members and open to all. If you're not already a member, please use the membership ticket to join and a free event registration will be included.

An increasing number of North American cities have now committed to an ambitious set of energy and greenhouse gas (GHG) reduction targets. There exist a range of HVAC retrofit best practices for GHG emissions reduction. Additionally, whole-building energy monitoring can ensure ongoing, high performance operation. The power of today’s transparent data and analytics can address avoiding the energy drift in projects which often results in savings degrading. Studies have shown that this can amount to as much as 30% in as little as 3 years time. Through active performance management, savings can be sustained through the long term. On average, building HVAC is responsible for about 40% of the energy consumption in commercial buildings. But this percentage is increasing as building owners increasingly adopt energy efficient lighting, leaving HVAC as the principal place to look for energy savings.

Over time, equipment in an HVAC systems tends to drift into ‘islands of set point controllers’. Some of the causes include manual interventions to address tenant comfort issues and changing functionality of buildings.These issues end up trapping approx. 30-40% of energy in energy wastage. We define this as the 'Energy White Space' in the building mechanical plants. Up to 30% energy savings can be achieved through control and optimization of the condenser loop, converting towers to variable flow and headering the cooling towers. Right-sizing presents yet another opportunity for energy savings. But the most reliable and informative connecting element in HVAC system is fluid flow (not pressure!) Flow rates inform decisions on operating speeds and equipment choices. Knowing real time flow information and rate of flow changes make possible the optimization of the performance of the entire HVAC system for improved efficiency and reduced operating costs. This presentation concludes with four real-world examples and results of HVAC best practices.
