[Bldg-sim] Bldg-sim Digest, Vol 77, Issue 17

[Asif Raza]

I am simulating an existing building in Revit 2014, can anybody guide me
what thermal properties i should use for building envelope? Should i use
typical values or should i have to measure physically? Walls are made up of
concrete blocks with plaster on both sides and slab is RCC.

>  *Features that will be covered: *
>
>  *1) Support for modeling refrigeration systems:  *
>
>  OpenStudio 1.3.0 introduces drag, drop and configuration capabilities to
> model the energy use of common commercial refrigeration systems (e.g.
> display cases and walk in coolers), including cascading systems. While this
> is not unique, the ability to integrate the energy impacts of refrigeration
> systems into a building’s heat balance at an adjustable sub-hourly time
> step provides tightly coupled feedback for estimating the interactions
> between energy systems.
>
>  *2) Support for modeling VRF HVAC systems  *
>
>  OpenStudio provides drag, drop and configure capabilities for modeling
> VRF (Variable Flow Refrigerant) HVAC systems and controls of varying
> complexity. VRF systems can be configured to operate in either a ‘heat
> pump’ mode, (where the system operates in either heating or cooling mode)
> or in a heat recovery mode (where indoor units can recover and exchange
> heat with other indoor units operating in the opposite mode). In addition,
> the outdoor units can be configured to be air, water or evaporative cooled.
> User defined performance curves (generated from manufacturers published
> performance data) can now be used to describe equipment performance.
>
>  *3) Support for modeling supply and return plenum configurations  *
>
>  Forced Air HVAC systems commonly use plenums for supplying and/or
> returning the conditioned air. This release of OpenStudio allows users to
> define and configure supply and return plenums that serve multiple
> conditioned zones. Plenums are considered unconditioned thermal zones and
> are composed of children OpenStudio spaces.  The plenum zones can leverage
> OpenStudio’s space type definitions for rapid object and property
> assignments.
>
>  *4) Support for incorporating ASHRAE Advanced Energy Design Guides
> (AEDG) 50% measures*
>
>  Thirty seven new OpenStudio measures from the ASHRAE K-2 and Small to
> Medium Office 50% AEDG have been added to the NREL BCL public measures
> library. These measures represent performance descriptions matching the
> published documents.  As such, these measures contain the logic needed to *easily
> & consistently* transform OpenStudio models to evaluate potential savings
> from incorporating high performance building and system components.  Easy
> application (drag and drop) of these measure to YOUR models will be
> demonstrated.

> Subject: [Bldg-sim] Updated Standard 90.1 Prototype Building Models
> Available
>
> Funded through DOE's Building Energy Codes Program, Pacific Northwest
> National Laboratory (PNNL) developed a suite of prototype building models
> to support the development of ASHRAE Standard 90.1. These prototype
> buildings–derived from DOE's Commercial Reference Building Models–cover 80%
> of the commercial building floor area in the United States for new
> construction, including both commercial buildings and mid- to high-rise
> residential buildings, across all U.S. climate zones.
>
>  As Standard 90.1 evolves and EnergyPlus is updated, PNNL makes
> modifications to the commercial prototype building models, with extensive
> input from ASHRAE 90.1 Standing Standards Project Committee members and
> other building industry experts. Updated models have recently been posted
> including the following major updates:
>
> 1. Standard 90.1-2013 models
>
> 2. EnergyPlus Version 8.0
>
> 3. TMY3 weather data.
>
>  The prototype models include 16 commercial building types in 17 climate
> locations for the four most recent editions of Standard 90.1 (2004, 2007,
> 2010, and 2013). The current combination results in an overall set of 1,088
> total building models. The building models and accompanying documentation
> can be downloaded at
