1 Optergy Enterprise + Proton Description In the small/medium sized building environment where air conditioning is required, it is common for Variable Refrigerant Flow (VRF) systems to be installed to maintain internal building conditions. VRF systems operate with multiple indoor air-conditioning units connected to a single outdoor condensing unit. Depending on each zone s condition, the refrigerant volume is varied to each indoor unit. These types of refrigerant systems are managed by their manufacturers proprietary controls which are typically mounted on the wall with small screen and buttons allowing basic functionality. VRF systems work well, however building owners have limited ability to improve on the VRF manufacturer's default settings. In small/medium sized buildings where VRF s are typically installed, all other operational systems are installed with basic timers and are independent of each other. These independent systems include (but not limited to): VRF systems Outside air fans Fire alarms Lighting control Elevator/Lifts General exhaust fans Toilet exhaust fans Kitchen exhaust fans CO monitoring and garage fan control Perimeter heating Auxiliary monitoring systems Electrical meters Gas meters Water meters Building with VRF and Siloed Systems Legend VRF outdoor unit Timer Roof Plantroom VRF indoor unit Lighting VRF wall controller Fire panel Lighting control CO CO sensor Level 3 Garage exhaust Electric meter Exhaust fan Variable speed drive (VSD) Gas meter Water meter Level 2 Level 1 Ground CO CO CO Parking Garage page 1 of 15

2 Typical VRF Building Environment Systems integration is typical in larger buildings with central heating, cooling and ventilation systems (HVAC), however is lacking in buildings with VRF systems. Historically, integrated systems have been too expensive to install on a smaller scale making integration impossible for building owners to justify. This left controls and automation contractors with little interest in offering integrated solutions which involve VRF systems. The problem with this legacy approach is when building systems are operated independently, building owners do not have remote access and end up with multiple systems that need to be operated locally. Lack of integration causes issues with: Problem Remote connectivity Adjustability Visibility Insight/diagnostic ability Analysis Reporting Effect An overall lack of control over building operations Lack of control over comfort conditions Increased operational expenses including - > Time lost traveling to site > Increased energy/water/gas costs > Increased maintenance costs To reduce risk and frustration from uncomfortable occupants, integration is what s needed to assure the whole building operates correctly with control placed back into the hands of the building owner.

11 Weather Data Optergy has a built-in weather interface that will let the users connect their weather stations. Common weather stations include Vaisala and Davis Instruments to provide accurate local weather data. Also included is the ability to connect to online weather station services. Currently, Optergy Software has three (3) weather stations: Vaisala WXT520 Weather Station - Onsite unit Davis Vantage Pro2 - Onsite unit Online service through API connection Weather & forecast displays are created automatically after configuration and can be used in foyer displays, dashboards, graphic displays, and can even be used in programming logic, as all data points available are converted into BACnet objects that can be trended and alarmed as needed.

12 After Hours Override & Billing In a typical commercial building, there is a lease agreement between owner and tenant which defines the core operating hours of the building. If tenants require air-conditioning or lighting base-building services outside the lease agreements core hours, the building owner can recover the additional costs of operating the building outside of these core hours. To recover these costs the building owner can allow the tenants to activate after hours utilities such as air-conditioning and lighting when working late. Upon activation, the user signals the system that they need a period of 30 minutes (adjustable) of air-conditioning and/or lighting (or any other service). The system will log the start time, check that the equipment is not normally scheduled on at the requested time, and also check that the equipment is running. Multiple tenants can be authorized to initiate the after hours event, and the events can be scheduled in advance (configurable number of days in advance). Bills can then be generated automatically, report of usage, and the appropriate tenants contacted automatically by . The bill itself can be configured to reflect property management branding, bill-to address, tax, charges (including time of use, demand, block, flat), custom header, pay to options, and automatic distribution.

14 Utility Billing Utilities such as electricity, gas, water and thermal (chilled & hot) can be easily metered/sub-metered and assigned to tenants for billing based on usage. Tenants that occupy multiple spaces can have multiple meters contribute to a single final bill per utility type. The bill itself can be configured to reflect property management branding, tariff charges, how to pay options and configured for automatic distribution.
