ASHRAE Annual Conference Sustainability Project Denver Rescue Mission Energy Efficiency Upgrades 1130 Park Avenue West, Denver, CO Learn

WHO In-depth energy assessment, technical design assistance, and the potential for high efficiency system installations WHAT... Our local ASHRAE chapter membership community Since 2008, each host city ASHRAE chapter has conducted a sustainability demonstration project of their choosing WHY...

2013 The Project 3-story, 23,000 sq.ft. building built in 1928 Tens of thousands of people come to this facility each year for shelter, food, and support

2013 The Facility Offices, two chapels, a library, a kitchen, a clinic, a dormitory and other ancillary spaces 3 meals per day, dorms open each night

2013 HVAC Systems Large boilers and steam radiators with old valves Constant volume make-up air unit (MAU) for dorms Constant exhaust for showers (4) split system AC units (offices, library, clinic) (4) evap cooling units (dorm, chapel, dining room)

Historical Energy Use 2013

Utility Data High EUI and Cost

2013 Utility Data Typical profile but high use

2013 Project Goals: Help the facility operate more sustainably with lower energy use and better Indoor Air Quality - Lower annual energy costs over 30%

Energy Efficiency Upgrades Lighting Upgrade 2.Replacement of (4) Split Systems 3.Installation of DDC System 4.Steam System Upgrades 5.Replacement of MAU with ERV 6.Replacement of (2) DHW Heaters, Increased Capacity, Low Flow Shower Heads 7.Installation of Solar DHW System

2013 ECM: Lighting Upgrade Currently 2 and 4-ft T-12 with magnetic ballasts Older exterior lights Limited occupancy sensors Older Exit Signs Project: Upgrade fixtures and add sensors

2013 ECM: Replace Split Systems Replacing (4) units - offices, library, clinic New units are 21 ARI Conditions *SEER = cooling output during a typical cooling-season divided by the total electric energy input during the same period(BTU/W*hr)

2013 ECM: Installation of DDC System Tie together HVAC equipment, zone thermostats, on/off enable Provide equipment scheduling, temperature control, unoccupied setback, and remote access

2013 ECM: Steam System Upgrades Thermostatic valves and steam traps in disrepair Replace valves and steam traps Address system leaks

2013 ECM: Replacement of Make-Up Air Unit (MAU) with Energy Recovery Ventilator (ERV) Tie restroom exhaust into ERV to capture heat Continuous ventilation for better IAQ

2013 ECM: Replacement of (2) DHW Heaters, Increased Capacity, Low Flow Showers Currently only (2) 80 gal tanks Adding more capacity and upgrading to 86% efficiency
