1. Remak Energy Consulting provides energy modeling and consulting services to help clients design more sustainable and energy efficient buildings. 2. They use tools like EnergyPlus, Sketchup, and advanced climate analysis to model a building's energy performance and evaluate different mechanical system options. 3. For one case study of a large shopping center in Russia, energy modeling helped identify the most cost-effective and highest performing mechanical system, saving the client energy costs over the life of the building.

2.
DELIVER THE CLIENT WITH ACCURATE AND WELL ARGUED
INFORMATION THAT IS PROVIDED IN A LANGUAGE HE UNDERSTANDS, RESULT AN
INCREASE IN POTENTIAL TO MAKE A BUILDING GREENER
EACH PROJECT IS UNIQUE. IT IS USUALLY WRONG GRABBING SOLUTIONS FROM
ONE PROJECT TOANOTHER UNLESS YOU’RE NOT SURE THE INPUT DATA AT SOME
EXTENT ARE COMPARABLE, BUT IT IS IMPOSSIBLE
3.
IT IS NECESSARY CAREFULLY INVESTIGATE SITE POTENTIAL PRIOR TO THINK
ABOUT ACTIVE SYSTEMS CONCEPT. TAKE ADVANTAGE OF IT

USE TOOLS THAT ALLOW QUICKLY AND EASILY GET, SHARE AND ANALYZE THE

CASE STUDY (cntd)
1.
THE CLIENT WANTS THE CHEAPEST SYSTEM. INVESTMENTS MAY BE FEASIBLE ONLY
WITH PAYBACK NO MORE THAN 10 Y.
2.
REC WAS INVOLVED BETWEEN THE DESIGN DEV AND CONSTRUCTION DEV PHASES.
THAT GIVES HUGE OPPOSITION FROM THE GENERAL DESIGNER (GD) AND SECOND
CONSULTANT (SC)
3.
GD AND SC FORCINGLY PERSUADE THE CLIENT TO TURN TO THE CENTRAL
SYSTEM (CH+FCU) GENERATING A LOT OF ADVANTAGES WHICH WERE NOT METRICS
MOSTLY
4.
WE’VE DONE ENERGY MODELLING USING ENERGYPLUS (BY US DOE) WITH
SKETCHUP
5.
INITIAL DATA PEER REVIEW WAS CONDUCTED AND SHOW HUGE SAVINGS
6.
ADVANCED CLIMATE ANALYZE ALLOW CLIENT MORE FEASIBLY FIX THE OA
DESIGN CONDITIONS (ASHRAE WEATHER DATA FROM 2013)
POTENTIAL JUST BECAUSE OF WITHDRAWING SAFETY-TO-SAFETY FACTORS AND
REVISING IAQ CRITERIAS

BUILDING PERFORMANCE (PASSIVE OPTIMISATION)

RESTRAINTS FOR INSTALLATIONS BETWEEN TENANT AND LANDLORD

CONSIDERING VERY TIGHT TIME FRAMES WE WERE ABLE TO ANALYZE ONLY TWO
BASIC CONCEPTS: CENTRAL WITH CH+FCU AND DECENTRAL WITH RTU+VAV

JUST INTERESTING FACT 1: TO PROPERLY MODEL ANNUAL ENERGY
CONSUMPTION FOR THE COOLING PLANT WE’VE GENERATED
- COOLING CAPACITY FUNCTION OF TEMPERATURE CURVE
- ELECTRIC INPUT TO COOLING OUTPUT RATIO FUNCTION OF TEMPERATURE
CURVE
THIS CURVES HAS CORRELATION COEFFICIENT NEAR 0.99. THIS ALLOW US TO
SEE REAL SEER FOR THE GIVEN OUT AND IN CONDITIONS

JUST INTERESTING FACT 2: IF DRIVE FOR ROTATING THE ROTARY WHEEL
(AHU) OPERATE 24/7 ANNUALLY IT CONSUMES NEAR 30% OF WHOLE COOLING
ENERGY OF THE BUILDING

JUST INTERESTING FACT 3: ANNUAL BILLS FOR THIS PROJECT

16. SUMMARY:
1.
APPROACH DESCRIBED ABOVE IS ESSENTIAL IF WE WANT TO KNOW AND
CONTROL WHAT WE’RE EXACTLY DESIGNING
2.
THE ONLY WAY TO UNDERSTAND THE BUILDING AND ITS PERFORMANCE IS
ENERGY MODELLING
WHAT ABOUT OUR EQUIPMENT:
1.
OUR AIM IS CREATED MORE SUSTAINABLE AND RELIABLE EQUIPMENT AND
REC SERVES HERE AS EXCELENT ASSISTANT IN THIS CHALLENGE. NOW WE MAY
PREDICT PERFORMANCE OF OUR EQUIPMENT IN THE GIVEN CONDITIONS PRIOR
TO THE DELIVERY IT ON SITE. IN THIS WAY WE MAY ADAPT AND OPTIMIZE ITS
CONFIGURATION CONSIDERING THE VERY CONDITIONS OF THE TASK.
THAT’S COOL

17. THE SYSTEMS CREATED IN E+ IS COMPLETELY
CUSTOMIZABLE

18. E+ DETALIZATION DEEP

19. GOOD NEWS:
1.
BUILDING CERTIFICATION.
BREEAM. OUR SERVICE GRADUALLY INCREASE POTENTIAL TO REACH RATING
“OUTSTANDING” IN MORE FEASIBLE WAY. THE MAIN DRIVE FOR THAT IS ENE1, OPTION 1
(15 SCORES AVAILABLE). WITH REC YOU HAVE HERE POTENTIAL IN 1.5 TIMES BIGGER.
LEED. OUR SERVICE GRADUALLY INCREASE POTENTIAL TO REACH RATING “PLATINUM” IN
MORE FEASIBLE WAY. THE MAIN DRIVE FOR THAT IS EAC2, OPTION 1 (18 SCORES
AVAILABLE). WITH REC YOU HAVE HERE POTENTIAL IN 3 TIMES BIGGER.
2.
WE MAY HELP YOU TO FIND BETTER SOLUTION. BE SURE,
WE’RE ON THE GREEN
SIDE
