Current recommendations being implemented include installing higher efficiency and lower wattage lighting, installing low-flow shower heads, installing automatic light sensor switches, placing energy management systems in some buildings, replacing existing exit signs with LED exit signs, and upgrading building systems. These energy projects have allowed 澳门金沙投注_任你博-官网 to generate and put into action a fully informed plan for smart energy use.
2021 Major Completed Initiatives
Dolphin Building Green Roof 2021 Stewardship Report
A green roof was previously installed atop the Dolphin Building. Green roofs conserve water and reduce run off by using otherwise unused roof top space to cultivate drought tolerant species of plants. These roofs require ongoing maintenance to be effective. This link documents the 2021 Stewardship report of the roof.
2019 Major Completed Initiatives

Fox Window Installation
The new low emissivity (Low-E) windows keep heat out during the summer and keep heat in during the winter. 澳门金沙投注_任你博-官网 installed high quality frames that include thermal window breaks, which reduce the transfer of heat, leading to more efficient heating and cooling of a space. Additionally, the windows have reduced the outside noise pollution from passing vehicles and trains that run along Howard Street.
Fox HVAC Installation
澳门金沙投注_任你博-官网 installed VRF (Variable Refrigerant Flow) devices to the Fox building in the summer of 2019. VRF is an alternative to traditional Heating, Ventilation, and Air Conditioning (HVAC) methods. The system is able to regulate the refrigerant flow through multiple evaporator coils, in order to provide individual temperature control in various mechanical comfort zones. Some key advantages of the VRF heating and cooling system are:
- The system runs very quietly.
- It has occupancy sensors in each area to only heat or cool when the space is occupied.
- It eliminates the need for a cooling tower and chiller, thus reducing the demand for water and chemical treatment of that water.
- Studies have shown the VRF system consumes 11% to 22% less energy that the conventional system due to the elimination of cooling towers and chillers.
- It provides much more balanced distribution of conditioned air within the building, so that the entire building is comfortable.
2018 Major Completed Initiatives
Boiler Upgrades
Two Fulton high efficiency gas boilers were installed to replace a low efficiency fuel oil boiler in late 2018. The efficiency rating of the new gas boilers are 94% compared to the previous fuel oil boiler, which had an efficiency rating of 65%.
Shower Stall Upgrade
澳门金沙投注_任你博-官网 upgraded the shower stalls in the Meyerhoff House in 2018. These upgrades included the installation of new shower diverters valves. The new diverters reduced previously leaky and dripping faucets, thus reducing the waste of water.
