En nergy An nalysis using u Co onceptua al Masse es - Besst Practices Whe en perform ming energy y analysis u using conce eptual massses, use th he following g guideliness. Kee ep it simple
Start with a sim mple mode el to study massing m an nd orientatio on on the project p site. Use e conceptua al energy analysis a during the early design phase p to en nsure that energy e use e and naturral reso ources are considered d during the e design se election pro ocess. Grea ater geome etric comple exity does not nec cessarily ressult in grea ater accuraccy during analysis. a Mod del only ma ajor spacess, and comb bine smalle er spaces th hat represe ent key requirements of the proje ect. You u do not need to define minor spaces like re est rooms, closets, or stairwells. By partitioning the sp pace into o more partss than nece essary, you u may intro oduce errorss and slow the simula ation withou ut significan ntly imp proving the accuracy of o the resultts. Use e a simple m mass with larg ge forms to represent major m partts of the dessign.
A com mplex masss consisting of many small forms ma ay resullt in errors and will not necessarily n p produce a more m accurate simulattion.
Ana alyze 3D vie ews
Perrform Energ gy Analysis s for Autode esk® Revit® ® using a 3 3D view in the drawing g area. Rev vit simulate es only the masses tha at display in n the 3D view. When the simulattion is complete, the Mas ss section o of the Resu ults and Co ompare dialog shows the mass th hat was sim mulated.
Use e meaningfu ul names fo or analyses
Whe en you starrt an simula ation, assig gn a concisse, meaning gful name so s you can differentiatte among simulations tha at use diffe erent forms and buildin ng parametters. Alig gn surfaces s
Durring simulattion, the typ pe of surfacce affects automatic a m modeling (s such as the e presence of glazing and skylighting) an nd impacts simulation results, inc cluding hea at loss or ga ain. Misalig gned surfacces can lea ad to simulation erro ors, such as interior wall w surface es analyzed d as exterio or wall surfa aces or floo or surfaces ana alyzed as ro oofs. To avoid a these e simulation n errors, model masse es accurate ely so that coincident surfaces a align properrly. Use e zoning
Typ pical therma al zoning co onsists of groups g of perimeter p ro ooms with exterior e exp posure, and d groups off core e zones witth little or no n exterior exposure. e For F concep ptual energyy analysis, you can usse automattic zones or custo om zones. Automatic zon nes
Use e automaticc zones when you wan nt to zone a building quickly. you are more conc cerned with the overall form of the building than t custom mizing the zoning layo out. you do n not yet know w how the building will be zoned d. Auto omatic zon ning provide es a basic idea i of zon nes and mo ore accurate e energy an nalysis at this concep ptual stag ge. Automa atic zones will w also update with any a change es you make to the overall mass form. To perform p a simulation s using u autom matic zones, use the Core C Offse et and Divid de Perimete er Zones optiions of the Energy Se ettings dialo og.
A mass m model w with perimetter zones
A masss model with h a core offse et and perim meter zones
Cus stom zones
Use e custom zo ones when you have h the buiilding might be zoned. e an idea how you are more intere ested in customizing the t zoning layout than n the overa all form of th he building. you are building an n energy model to exp port to gbXM ML, and yo ou want the e zones to be b correctlyy d. modeled To enable e cusstom zoning g at the pro oject level or o the masss level, turn n off the Div vide Perime eter Zones optiion, and sp pecify 0 (zero) for Core e Offset. Cre eate zones by modelin ng separate e forms insiide a masss, cutting on ne mass forrm from an nother. Whe erever a fo orm is inters sected by a mass floo or, the simu ulation interrprets a sep parate masss zone. Usin ng one masss for the main building with w automattic zone es gives thiss result.
Defin ning a mass form in the main buildin ng gives a differrent zoning result. r
To create c an a atrium, crea ate a smalle er atrium mass m form that has a different d ma ass floor co onfiguration n from m the larger mass mod del. Place the t atrium mass inside the large er mass mo odel.
Sim mplify a com mplex mode el
Sim mulation ma ay fail on models with curved surrfaces or co omplex sha apes becau use these surfaces are e face eted by the e system. Automatic A zo oning (defined using a core offse et and divid ded perime eters) furthe er incrreases the complexityy of the mod del. If simulation fa ails, modify the model by simplify ying or rem moving curves. Curv ved surfaces or complex shapes may cause the simu ulation to faiil.
Chan nge curves into facets fo or a successsful simulatio on.
In a complex m model, replace the use e of automatic zones with custom m zones to o simplify th he core. Durring concep ptual energy analysis, Revit can simulate th he following g maximum m numbers o of surfacess, ope enings, and spaces: Exterior su urfaces: 819 92 92 Interior surrfaces: 819 und surface es: 8192 Undergrou 4 Shade surffaces: 1024 Openings: 8192 096 Spaces: 40 Exp periment
Try using diffe erent simple e forms to determine d w which chan nges have the t largest impact on energy consumption o or allow the e most enerrgy generation potential. Certain n building parameters influence ene ergy consum mption morre (or less) than you might m expecct due to th he building type t and lo ocation. For example, e experimentt by running g an analyssis on a mo odel that usses a large amount off high perfforming gla ass. Then run a secon nd analysis on a mode el that usess low perforrming glasss. Compare e the results to ssee whethe er modifying g the glasss has a sign nificant imp pact on energy consum mption for the t a location n. building type and The e energy co onsumption n of building gs with high h occupanccy rates or equipment densities (such ( as assembly build dings, data a centers, convention centers, c an nd theatres) often dep pends on asssumed hours o an nd intensity y of operation. For the ese building g types, it is s importantt to determine the of operation simulation parrameters that are the primary p drivvers of ene ergy consum mption.

Create masses s to define shading s ob bjects
If nearby buildings or structures will shade your building, you can model them to ensure that the conceptual energy analysis incorporates their effects on your building. For the energy analysis, you can hide or omit any buildings that do not directly shade the model. 1. Create a simple mass form that approximates the size and position of the other building. Note: Do not apply mass floors to this form. If you apply mass floors to shading objects, Revit performs energy analysis on them as well, which will slow the analysis and may exceed analysis limits. 2. Create a mass model for your building design, add mass floors, define energy settings, and analyze the mass model as described in the Energy Analysis using Conceptual Masses - Quick Start. When a mass does not have mass floors, Revit considers it to be a shading object for the purpose of energy analysis.

The e building tyype include es assumpttions about the typicall schedule of the build ding based on usage. For insttance, a rettail store is assumed to t be open more hourrs per year than an offfice building g, and so itt use es more ene ergy. Whe en preparin ng for an en nergy analyysis, you ca an use the Building Operating O Schedule op ption to ove erride the de efault sche edule for the e specified building tyype. You ca an also override the sp pace assignments fo or specific zones. Gro ound Plane
Spe ecify the levvel to use as a the ground plane re eference fo or the building. Durring analysiis, spaces below this level are co onsidered to t be underrground. Th hey do not include glaz zing, and th he undergro ound walls can use a different co onstruction n than abovve-ground walls. w Ground Plane = Level 1. Th he mass mo odel includes s zing on all le evels. glaz
Grou und Plane = Level 2. The e mass mod del removes glazing from Levvel 1.
For a building where the ground floo or is partiallly undergro ound (for example, bu uilt into a slope), use the t el with the m most expossure as the e ground pla ane. The diifferences in i the resullting energyy analysis are a leve typically fairly minor. Loc cation

Mass Shade
Select Basic Shade. Mass shades are assumed to be opaque. Use shades and overhangs to reduce cooling loads, minimize solar heat gains, and increase comfort. For projects with smaller internal loads, such as residential buildings, overhangs can potentially increase heating loads. This issue is typically not a concern with large non-residential projects due to their higher internal heat gains.
Mass Opening
Select Air. Openings are modeled as voids in surfaces that are exposed to climatic conditions. In the Energy Settings dialog, click Edit to open the Conceptual Constructions dialog, where you can specify the constructions to use for different types of mass surfaces. For walls, roofs, floors, and slabs, the tables in the following sections show Imperial (IP) values, which are calculated as follows:
