Mitsubishi City-Multi ceiling unit
1.4 Quality / availability of equipmentAll of the technologies and equipment being proposed are high-quality off-the-shelf products, currently available.
Closed cell spray foam, Energy Recovery Ventilators, and high-performing wood windows are prevalent throughout the Commonwealth.
Building Energy Dashboards are rapidly becoming more widespread, especially on college campuses in the state. Boston College, for instance, has networked 25 residences for display on a single dashboard and initiated a campus-wide competition to reduce electric consumption, resulting in an estimated 15000 kwh saved over the course of their “NRG Games”.
1.5 RisksThe risks involved in Air Sourced Heat Pumps are ones of half-measures.
The Mitsubishi City-Multi Air Sourced Heat Pumps have excellent Coefficients of Power, from 2.2 to 3.9, but the reliance on electrically-driven heating - without significant load reductions -will not by itself decrease reduce primary (source) energy consumption, reliance on the fossil-driven electric grid, or the carbon output of Union Crossing.
In combination with air sourced heat pumps, envelope-based load reductions can reduce both site and source energy required, resulting in lowered energy consumption, lower cost, and lower carbon outputs.
Without these significant reductions, electrically-driven heating of aging mill buildings may also drive large peak demands. In general, eQuest modeling of this project has shown that the upgrade package proposed increases demand during some “shoulder” months, while decreasing demand at other times - during summer. This “smoothing” of the demand curve will be of benefit to the grid at large.Union Crossing will tread more lightly on the electric grid than its standard practice contemporaries.
The risk of monitoring is that its messages will go unheard. Installation of even the most advanced measuring systems requires diligent follow-up and on-going behavior modification to be of real value.
Lawrence CommunityWorks and the tenants at Union Crossing will engage in active education literacy campaigns to pursue continuous energy reductions, based on feedback from the monitoring systems to be installed. Success in similar education programs indicates good reason to expect success in this field.
