Energy Saving Objectives

Heating, Ventilation, and Air Conditioning (HVAC)

The basic plan for the HVAC system will be provided by geothermal well water (two wells under the Vine Street sidewalk), driving a Variable Refrigerant Flow (VRF) heating and cooling system.  By operating at varying speeds, VRF units work only at the needed rate, allowing for substantial energy savings at partial-load conditions.  Heat recovery VRF technology allows individual indoor units to heat or cool as required.  Energy savings up of up to 55% are predicted over traditional HVAC equipment.  Where required outside makeup air enters the HVAC system, it will be tempered using low energy heat exchangers.  In addition, CO2 sensors will regulate the need for makeup air, drastically reducing the consumption of energy to moderate the incoming outside air in all seasons.

In the large opera house audience chamber with its high ceilings, hydronic floor heart will be used.  It will reduce energy consumption by delivering heat to the floor area where people are and not heating air near the ceiling.


Hot water for space heating and potable water heating will be generated using a 96% efficient hot water modulated boiler system.

Modulating circulating pumps will regulate water flow throughout the building, reducing energy consumption based on need and time of day.

Devices such as toilet fixtures that do not require potable water will be fed by geothermal discharge waste water, thereby minimizing the use of the city potable treated water.


Interior storm windows will be used to save energy and block reduce outside noise while preserving the historic integrity of the window matrix.  Where window replacement is required, high energy windows will be used.

All materials that are made available from demolition process will be preserved and reused to the greatest extent possible in the restoration project.  In addition, the project objectives dictate that in the historic portions of the project, all existing elements of the building that can remain and/or be reused will remain and/or be reused.

The complete project will allow for an aggressive recycling program to be implemented within the combination of the facility occupancy and tenants alike.


All common light fixtures will be of LED or hi-efficiency florescent design.  LEDs have many advantages over incandescent light sources, including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching.  Lamps for historic fixtures will also be LED wherever available and practical.  All new theatrical systems will be of the LED type, wherever available and practical.  All supporting dimming and control equipment will be of the low energy consumption type.


All sound systems will be state-of-the-art, low energy consumption equipment.

Electricity Source

While not in the current project, we are investigating installing a photo voltaic array on the annex roof to provide some of the electricity required to operate the complex.
