Cypress Envirosystems is a subsidiary of Cypress Semiconductor and the sister company of SunPower. Their mission is to enable existing buildings and old plants to save energy by installing the latest automation technologies with minimal cost, invasion and labor.
Demand Response and Energy Efficiency for Existing Buildings
Cypress Envirosystems thermostat solutions are specifically designed for existing commercial and industrial buildings. Their easy-to-install solutions are meant to give a building demand response capability, saving them energy.
The Wireless Pneumatic Thermostat (WPT) is meant to give a building the benefits of Direct Digital Control (DDC) for minimal install time and cost.
The WPT enables demand response strategies. Its features include remote wireless setpoint control, remote monitoring of temperature and pressure, programmable temperature setbacks, and pager or cell notifications of excursions.
Also, the WPT has a BACnet interface to BMS. The thermostat can either work alone, or with a building automation system - it is compatible with many systems including Johnson, Honeywell, Siemens and Robertshaw.
Since the installation process is non-invasive, the WPT takes less than an hour to install (as little as 15 to 20 minutes), which means they cost 60-80% less than their competitors. Also, the WPT has qualified for several utility incentives for energy efficiency and demand response (see DSIRE to see if your project would qualify). Cypress Envirosystems claims that the thermostats have a payback period of 18 months or less.
Because of its innovative, cost-effective method of improving energy efficiency and giving demand response capability, Cypress Envirosystems’ WPT was rated as one of BuildingGreen’s top 10 green building products for 2012.
Cypress Envirosystems’ thermostats mostly apply to LEED for Existing Buildings: Operations and Maintenance (LEED EB:O+M) because they are specifically designed for existing commercial and industrial building retrofits.
The WPT could help a LEED EB:O+M project to earn the following credit:
Energy and Atmosphere (EA) Credit 2, Existing Building Commissioning:
The purpose of this credit is "through a systematic process, to develop an understanding of the operation of the building's major systems, options for optimizing energy performance and a plan to achieve energy savings". Essentially, the WPT can contribute to this credit by helping the facility managers to continually asses how they can make no or low-cost improvements that will improve the building's energy efficiency.
This credit has three components, each worth 2 points: Investigation and Analysis (Credit 2.1), Implementation (Credit 2.2.), and Ongoing Commissioning (Credit 2.3).
The WPT could help with all three components, since it can be included as part of the investigation and commissioning plan for the building's major energy-using systems (Credit 2.1), could help to implement no or low-cost operational improvements (Credit 2.2), and can be used as part of the building's ongoing commissioning plan (Credit 2.3).
Also, the WPT could indirectly help to earn EA Credit 3, Performance Measurement, because it can work in tandem with a building automation system (which the credit requires).
