In this event we get together to host four different presentations were we explored interesting questions regarding some of the most current topics in the building performance simulation world such as Net Zero designs and some public initiatives to facilitate the effective implementation of energy modeling tools.
1. Development of a Unified Tool for Analysis of Room Loads and Conditions
Presenter: Peter Simmonds, Managing Director/Principal at Building and Systems Analytics LLC
ABSTRACT: The objective of this work is to produce a unified space analysis application that calculates and displays room conditions, heating and cooling loads (delivered by air-based and/or radiant systems), mean radiant temperature (MRT)and PPD/PMV comfort conditions. This application is named RPEHB, since it is an integration of RPE with the HB (heat balance) load calculation method. The inputs for RPEHB calculations are room shape, construction, operational requirements (e.g. control set points), and design-day weather conditions. Preparation of geometric input data will be supported by import from 3D tools (SketchUp). While these objectives were ambitious, it must be emphasized that the work required integration of existing software, not original research or development. The goal is to combine the product of years of ASHRAE research to yield capabilities that can be conveniently applied in actual design work.
2. Simulation for Optimizing Building Controls Systems
Presenter: Jeff Landreth, Director Energy and Sustainability at Tk1sc
ABSTRACT: This presentation summarizes strategies for utilizing simulation as a tool for optimizing building HVAC controls systems. The presentation covers various workflows and simulation approaches for identifying and quantifying building performance improvements for building HVAC control systems. It also covers several case studies where simulation was used to identify building specific control strategies.
3. Architecture at Zero Design Competition
Presenters: Jed Donaldson, Associate Principal at Johnson Fain & Greg Collins, Principal at Zero Envy
ABSTRACT: NZ@Block15 is a collaborative project between an Architect and a Sustainability Engineer. NZ@Block15 is 463 residential units over 36,000 sf of retail/ community space. The project is a Net Zero Building for the University of California San Francisco Mission Bay Campus. The process of design included the study of building site placement, building massing, selection of building systems, passive building strategies and the generation of innovative technologies used to bring the project towards Net Zero energy performance. The competition entry, NZ@Block15, will be presented from the perspective of an architect and may outline the trials and tribulations of learning of engineering technologies that are traditionally within the wheelhouse of the engineer. The entire project was designed using advanced computer technologies and the team leveraged the parametric data to explore iterative square footage analysis as well as energy modeling scenarios. The design solution for NZ@Block15 was successful and submitted in 2015 and now the team has turned their attention to the 2016 competition but refocused their goals towards a Net Positive agenda.
4. Taming the BEAST (Building Energy Analysis & Simulation Tools): A Public Vision for Leveraging Simulation to Accomplish Statewide Goals
Presenter: Will Vicent, CEM, LEED AP, Owner at Between Built & Natural Environments
ABSTRACT: California is leading a country-wide charge to move newly constructed buildings to Zero Energy. The unsung hero for making all this happen is building energy modeling (BEM). Considering the increasingly pivotal role of BEM, Southern California Edison (SCE) – one of the nation’s largest electric utilities – has embarked on a long-term BEM planning effort: the SCE Building Energy Analysis & Simulation Tools (BEAST) Roadmap. This work, hot off the press, aims to guide long term advancements in BEM and can serve as a template for similar economies to participate in a shared public vision for BEM.
