TWC is proactive in energy-saving practices when planning repair and maintenance projects and tracking energy consumption. The fiscal 2020 EWMP included several projects carried over from fiscal 2019 that involved replacing old systems with energy-saving systems. These projects, which are listed below, were completed in fiscal 2020, and TWC expects to see a decrease in energy consumption this year.
The fiscal 2020 completed projects include:
- Fort Worth – boiler replacement
- Austin Criss Cole Rehabilitation Center (CCRC) air-handling unit (AHU) make-up air unit
- Austin Guadalupe HVAC replacement
- Austin Annex AHU reconfiguration
TWC identified two new energy-saving projects in the fiscal 2020 EWMP:
- Austin Main – window/glazing replacement
- CCRC – walk-in cooler/freezer replacement
The CCRC project is under way and completion is expected by December 2020. A decision was made to postpone the Austin Main project until fiscal 2022 due to complications that arose in trying to assess the presence of asbestos and coordination of urgent projects in the Annex facility.
TWC has been recognized for its practices by the award of ENERGY STAR® ratings on six of the 24 agency-owned buildings (AOBs). Five AOBs have received ENERGY STAR® awards for eight consecutive years, from 2013 to 2020. Since the AHU was replaced in the Austin Annex facility, it now qualifies for an ENERGY STAR® award; TWC will apply for it.
facility, it now qualifies for an Energy Star® award. TWC will apply for the award.
The impact of most staff teleworking during the COVID-19 pandemic, coupled with TWC’s ongoing conservation efforts, resulted in decreased utility usage in fiscal 2020.
- Total electricity usage was 11,673,818 kilowatt hours (kWh), which represents a 12 percent decrease from fiscal 2019. Usage in fiscal 2020 was 8 percent lower than projected.
- Total water usage was 11,559,050 gallons, which is a 23 percent decrease from fiscal 2019. Usage in fiscal 2020 was 14 percent lower than projected.
- Total natural gas usage was 6,572 thousand cubic feet (MCF), which represents a 50 percent decrease from fiscal 2019. Usage in fiscal 2020 was 32 percent lower than projected.
Usage will be lower while staff continue to telework, but TWC expects an increase once staff return to their offices. TWC will report usage updates on a quarterly basis during fiscal 2021.
The goals for reducing electricity, water, natural gas and gasoline consumption are outlined in the table below. The benchmark year of fiscal 2020 for electricity consumption is legislatively mandated (see Health and Safety Code §388.005). fiscal 2017 remains the benchmark year for the other utilities, as first reported in the fiscal 2017 EWMP when vocational rehabilitation programs were transferred to TWC, resulting in increased utility consumption.
|Utility||Target Year||Benchmark Year||Percentage Goal|
STRATEGY FOR ACHIEVING GOALS
- Continue installation of Building Management System (BMS) software. BMS will be installed in the Austin Annex and Austin Guadalupe facilities. BMS allows TWC to monitor systems to identify needed
- Replace light fixtures with energy-efficient
- Replace equipment with energy-efficient equipment models on a continuous
- Use energy and water conservation design standards adopted by SECO in accordance with 34 Tex. Admin. Code §§ 19.31-19.34. Before beginning repair, TWC will submit certification from the project design architect or engineer to SECO to verify the project complies with SECO
- Install cool roof when roof replacement is
- Conduct energy-related activities on a set schedule as outlined in the TWC Facilities Master Plan (FMP):
- Electrical testing and repairs
- Envelope and water penetration inspections and repairs
- Sprinkler systems testing and repairs
- Gas/plumbing testing and repairs
- HVAC/boiler inspections for proper functionality
- Roof inspections and repairs
- Structural inspections
- Engage in competitive utility procurement, where available. The following contracts help support TWC’s goals to reduce energy consumption:
- SECO, in conjunction with the Council on Competitive Governments, contracts with ENGIE Insight Services Inc. (ENGIE) to assist TWC with energy needs, decision-making and renegotiating energy contracts in deregulated areas. ENGIE analyzes utility bills and monitors TWC’s energy and water usage. ENGIE contracts with TXU Energy Retail Company LLC (TXU Energy) for lower
- TWC participates in a statewide consortium via an interagency contract (IAC) with the General Land Office (GLO) to purchase natural gas produced on state-owned land. This arrangement allows TWC to purchase natural gas from GLO at reduced rates for all Austin AOBs and one leased site. TWC will expand this contract to new sites for which this is
- Continue replacement of TWC Capitol Complex exterior lighting with LED motion-controlled lower energy lighting or by
- Activate power management settings that turn off or reduce use of networked IT assets based on business hours and periods of low
- Turn off lights in unused offices, conference rooms, hallways etc. at peak hours, where feasible, especially during triple-digit heat
The following projects are expected to reduce energy consumption. The project listed as ongoing is carried over from fiscal 2020 and is scheduled to be completed in December 2020. The fiscal 2021 projects will begin this fiscal year.
- CCRC – walk-in cooler/freezer replacement
- Austin Annex and Trinity – window/glazing replacement
- Austin Annex – replace cooling tower
- Austin Main – Building Management System upgrade
AGENCY FINANCE STRATEGY
TWC identifies and schedules maintenance and repair projects for energy efficiency, which are implemented with appropriated funds. The budget and cost estimates for fiscal 2021 projects that impact energy consumption are included below.
Total Budgets for Repair and Maintenance
- fiscal 2021 capital projects – $2,178,118 (includes $429,975 for CCRC)
- fiscal 2021 facility-related maintenance and repairs – $3,793,781
Estimated Cost of fiscal 2021 Projects with Energy Usage Impact
- CCRC walk-in cooler – $411,578
- Austin Annex and Trinity – window/glazing replacement, $853,125 and $708,191
- Austin Annex – replace cooling tower, $774,210
- Austin Main – Building Management System upgrade, $690,000
EMPLOYEE AWARENESS PLAN
TWC sends an annual communication to all employees about ways to conserve energy and solicits employee feedback for new energy-savings ideas. Tips and ideas for conserving energy are also published on the agency intranet, which are available to all employees.
