Protect our earth today for our children’s tomorrow

VISUALIZATION OF THE DESIGN PHASES AND ITS INFLUENCE ON EFFORT/EFFECT CAPABILITIES

1. STAY ON PD, AND SD2. VARIANT DESIGN

PRELIMINARY APPROACH TO OBTAIN RIGHT PASSIVE TECHNIQUES

CHOOSING THE RIGHT DECISION FOR THE VERY GIVEN TASK

1. 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

2. 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

4. ANALYZE THE OPTIONS. DO THE PARAMETRIC STUDY

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

6. BE UPDATED

THAT’S HOW REMAK ENERGY CONSULTING FEELS

REMAK ENERGY CONSULTING INVOLVED

ASTRAPARK SHOPPING CENTER (RUSSIA). 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 POTENTIAL JUST BECAUSE OF WITHDRAWING SAFETY-TO-SAFETY FACTORS AND REVISING IAQ CRITERIAS

6. ADVANCED CLIMATE ANALYZE ALLOW CLIENT MORE FEASIBLY FIX THE OA DESIGN CONDITIONS (ASHRAE WEATHER DATA FROM 2013)

ASTRAPARK SHOPPING CENTER (RUSSIA). CASE STUDY (cntd)6. ENERGY MODELING ALLOW US FIND PARAMETERS WHICH DRIVE

THE BUILDING PERFORMANCE (PASSIVE OPTIMISATION)

7. THE RESPONSIBILITY DESIGN FRAMES WAS DEVELOPED TO SPECIFY RESTRAINTS FOR INSTALLATIONS BETWEEN TENANT AND LANDLORD

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

DECENTRAL WITH RTU+VAV

BOILER AND CHILLER HEATING RATES

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

THE SYSTEMS CREATED IN E+ IS COMPLETELY CUSTOMIZABLE

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.
