This presentation explores the challenges and opportunities in achieving energy savings in multifamily buildings from an “on the ground” perspective. Utilizing case studies and examples from recent CEE research and energy efficiency programs, this presentation provides an overview of technologies and strategies that have proven to be effective and marketable energy efficiency measures in MN multifamily buildings, including; ventilation system retrofits, optimizing boiler control systems, optimizing condensing boilers, retrofitting trash chutes, and adding demand-based controls to domestic hot water recirculation pumps.

Homeowners with natural gas water heaters have difficulty justifying the expense of a more efficient condensing heater. Combination space and domestic hot water systems bundle together the two loads, which saves energy and makes them more cost-effective. These systems also help eliminate combustion safety concerns.
Historically, mechanical contractors have custom engineered and pieced together combi systems in the field, paying little attention to efficiency and optimization. But condensing heating plants will only reach their energy saving potential when all components are designed and installed correctly.

Small Council, Big Vision, Bigger Savings - AIRAH Pre-loved Buildings 2014Yale Carden
Presentation showing the incredible energy savings potential of geoexchange / ground source heat pumps for heating and cooling commercial buildings. This presentation was delivered at the AIRAH Pre-loved Buildings Conference in Brisbane, Australia in October 2014.
Titled Small Council, Big Vision, Bigger Savings, it takes the audience on the journey of this project from initial concept through to completion. It discussed both the incredible energy and dollar savings while also addresses the importance of the project team and their importance in delivering what was a truly great project.
Using the Ground for Thermal Energy Storage: The Experience of the Riverina H...Yale Carden
All buildings interact with the ground for its ability to support their foundations. However, very few buildings interact with the ground for its ability to provide thermal energy storage. We have all experienced the moderate temperatures within a cave at depths of just a few metres. These temperatures are a function of average annual air temperature and are the result of the ground absorbing and storing solar energy. The use of this indirect and renewable solar energy can provide significant energy savings for heating and cooling systems.
A Ground Heat Exchanger (GHX) provides the ability to utilise the ground for thermal energy storage, essentially transforming the ground into a thermal battery. It enables us to extract heat from it in winter (heat source) and return that heat in summer (heat sink). It is a dynamic thermal battery that operates both simultaneously and over the annual heating / cooling cycle.
This presentation will provide an overview of how the ground is being utilised for its thermal energy storage capabilities around the world, with focus on a local installation at the Tumut Council owned Riverina Highlands Building, located in Tumut NSW. The installation has provided Council with energy savings on heating and cooling of 80 %, reduced peak energy loads by 40%, reduced maintenance costs and, importantly, provided significantly higher levels of occupant comfort. This has also increased the capacity and effectiveness of the concurrently installed solar PV array and will ensure that future solar energy storage will have greater impact.

Utilization of Computer Room Cooling Infrastructure: Measurement Reveals Oppo...Upsite Technologies
Study of data centers reveals the average computer room has cooling capacity that is nearly four times the IT heat load. When running cooling capacity is excessively over-implemented, then potentially large operating cost reductions are possible by turning off cooling units and/or reducing fan speeds for units with variable frequency drives (VFD). Using data from 45 sites reviewed by Upsite Technologies, this presentation will show how you can calculate, benchmark, interpret, and benefit from a simple and practical metric called the Cooling Capacity Factor (CCF). Calculating the CCF is the quickest and easiest way to determine cooling infrastructure utilization and potential gains to be realized by AFM improvements.
