Friend Town Setagawa is a neighborhood shopping center opened in the 21,000 square-meter site of the former First Shiga Plant of Sanyo Electric. It is situated adjacent to Karahashi Park along National Route 1 and the Seta River. In designing this shopping center, full consideration was paid to providing the highest level of hospitality for shopping center visitors in terms of facilities and service. In line with this concept, universal design was pursued wherever possible, eliminating differences in floor levels and enabling easy wheelchair accessibility. All equipment in use was also required to be eco-friendly.
Challenges related to equipment:
1. Efficient use of natural energy sources including sunlight.
2. Deployment of energy-efficient equipment that consumes less electricity.
3. Energy conservation through optimal control of air conditioners, lighting equipment, and freezers/refrigerators.
For the construction of this shopping center, various plans were adopted to ensure effective use of natural energy sources. In the area of architectural design, devices designed to illuminate a shop interior without the need for electricity were installed at 23 locations in the shopping center. These devices use special aluminum tubes that reflect sunlight. In the area of equipment, 374 polycrystalline photovoltaic (PV) cell modules were installed on the building rooftop along with 76 modules placed on the walls. Together, these modules deliver a maximum power output of 100kW. All of the power generated by this system is sold to an electric utility company. The total output per year is estimated at 87,000kWh, which corresponds to approximately 6% of the amount of electricity consumed throughout the shopping center in a year.
Virtually all lights throughout the shopping center are LEDs, including lighting fixtures used on sales floors, signage, and even street lights. In addition to reduced power consumption, longer life means lower discard rates of end-of-life light bulbs. Freezer systems for supermarket showcases utilize environmentally friendly R410A refrigerant with zero ozone depletion potential. Inverter-based precise temperature control and the use of showcases with built-in LED lights also help cut running costs.
Panasonic's total air conditioning control system (P-AIMS) accumulates operational data of all lighting and air conditioning units installed at Friend Town Setagawa. The system enables visualization of each equipment piece's power consumption, the illumination status of lighting equipment, as well as the temperature setting and operational status of air conditioners. The PV power output can be checked on the signage monitor installed at the "eco-miru" area, which provides information about the shopping center's environmentally responsible initiatives.
Operational data of lighting and air conditioning equipment as well as freezers/refrigerators is sent via Panasonic's integrated store management system, Eco Store System Plus, to the Panasonic remote monitoring center's server, where it is accumulated and stored. Along with remote monitoring of equipment operational status, the remote monitoring center provides optimal control for reducing power consumption. Peak demand of each piece of equipment is also monitored and operations are controlled to prevent power consumption from exceeding the predetermined peak level. Each store's equipment operation can also be remotely monitored from the Heiwado headquarters, enhancing management efficiency by tracking each store's conditions.
