AlfaTech Sustainability Presentation 2020

Energy Modeling & Lifecycle Cost (LCC) Analyses

Strong background in project related conservation design: energy analysis, energy reports with payback analysis, lighting technologies, and use of variable frequency drives to control HVAC equipment and systems.

HVAC SYSTEMS

High efficiency water-cooled chiller and cooling tower designs

• Day lighting systems • Interior Lighting systems • Energy efficient HVAC systems

Photocontrols for illuminance levels Photocontrol regulation of day lit area(s)

Use of high efficiency chillers with turbo core’s multiple magnetic bearing and oil free compressor for low load condition Use of hybrid heat-pump/heat- recovery chiller in place of pony chillers for low load condition Reduce reheat by means of exterior fan-coil unit with ECM motor and variable floor versus VAV with reheat

INTERIOR LIGHTING SYSTEMS LED Light Fixture Occupancy sensors Lumen maintenance controls Improved lighting design

Through whole building energy modeling analysis, provide recommendations for Net Zero strategies and to enhance core and shell MEP systems, including: • Eliminating gas-fire equipment (boilers and kitchen equipment) • Reducing reheat by means of perimeter highly efficient hybrid 2/4 pipe fan-coil system • Use water side economizer • Thermal storage
